4 *** Version 3.0.34 stable ***
7 - Improve the handling of chunk-encoded responses by buffering the data
8 even if filters are disabled and properly keeping track of where the
9 various chunks are supposed to start and end. Previously Privoxy would
10 merely check the last bytes received to see if they looked like the
11 last-chunk. This failed to work if the last-chunk wasn't received in one
12 read and could also result in actual data being misdetected
14 Should fix: SF support request #1739
15 Reported by: withoutname
16 - remove_chunked_transfer_coding(): Refuse to de-chunk invalid data
17 Previously the data could get corrupted even further.
18 Now we simply pass the unmodified data to the client.
19 - gif_deanimate(): Tolerate multiple image extensions in a row.
20 This allows to deanimate all the gifs on:
21 https://commons.wikimedia.org/wiki/Category:Animated_smilies
22 Fixes SF bug #795 reported by Celejar.
23 - OpenSSL generate_host_certificate(): Use X509_get_subject_name()
24 instead of X509_get_issuer_name() to get the issuer for generated
25 website certificates so there are no warnings in the browser when using
26 an intermediate CA certificate instead of a self-signed root certificate.
27 Problem reported and patch submitted by Chakib Benziane.
28 - can_filter_request_body(): Fix a log message that contained a spurious u.
29 - handle_established_connection(): Check for pending TLS data from the client
30 before checking if data is available on the connection.
31 The TLS library may have already consumed all the data from the client
32 response in which case poll() and select() will not detect that data is
34 Sponsored by: Robert Klemme
35 - ssl_send_certificate_error(): Don't crash if there's no certificate
36 information available. This is only relevant when Privoxy is built with
37 wolfSSL 5.0.0 or later (code not yet published). Earlier wolfSSL versions
38 or the other TLS backends don't seem to trigger the crash.
39 - socks5_connect(): Add support for target hosts specified as IPv4 address
40 Previously the IP address was sent as domain.
42 - General improvements:
43 - Add a client-body-tagger action which creates tags based on
44 the content of the request body.
45 Sponsored by: Robert Klemme
46 - When client-body filters are enabled, buffer the whole request
47 before opening a connection to the server.
48 Makes it less likely that the server connection times out
49 and we don't open a connection if the buffering fails anyway.
50 Sponsored by: Robert Klemme
51 - Add periods to a couple of log messages.
52 - accept_connection(): Add missing space to a log message.
53 - Initialize ca-related defaults with strdup_or_die() so errors
54 aren't silently ignored.
55 - make_path: Use malloc_or_die() in cases where allocation errors
56 were already fatal anyway.
57 - handle_established_connection(): Improve an error message slightly.
58 - receive_client_request(): Reject https URLs without CONNECT request.
59 - Include all requests in the statistics if mutexes are available.
60 Previously in case of reused connections only the last request got
61 counted. The statistics still aren't perfect but it's an improvement.
62 - Add read_socks_reply() and start using it in socks5_connect()
63 to apply the socket timeout more consistently.
64 - socks5_connect(): Deal with domain names in the socks reply
65 - Add a filter for bundeswehr.de
67 - Action file improvements:
68 - Disable filter{banners-by-size} for .freiheitsfoo.de/
69 - Disable filter{banners-by-size} for freebsdfoundation.org/
70 - Disable fast-redirects for consent.youtube.com/
71 - Block requests to ups.xplosion.de/
72 - Block requests for elsa.memoinsights.com/t
73 - Fix a typo in a test.
74 - Disable fast-redirects for launchpad.net/
76 - Stop unblocking .org/.*(image|banner) which appears to be too generous
78 https://stats.noblogs.org/piwik.php?action_name=anti%20gentrifizierungs%20fest&idsite=10175&rec=1&r=220192&h=17&m=7&s=44&url=https%3A%2F%2Fmuellemcalling.noblogs.org%2F&urlref=https%3A%2F%2Fmuellemcalling.noblogs.org%2Finfostande%2F&_id=&_idn=1&_refts=0&send_image=0&cookie=1&res=1366x768&pv_id=eqr7jX&pf_net=7&pf_srv=3&pf_tfr=2281&pf_dm1=156
80 The example URL http://www.gnu.org/graphics/gnu-head-banner.png is
81 already unblocked due to .gnu.org being unblocked.
83 - Disable filter{banners-by-link} for .eff.org/
84 - Block requests to odb.outbrain.com/
85 - Disable fast-redirects for .gandi.net/
86 - Disable fast-redirects{} for .onion/.*/status/
87 - Disable fast-redirects{} for twitter.com/.*/status/
88 - Unblock pinkstinks.de/
89 - Disable fast-redirects for .hagalil.com/
92 - Bump version to 0.9.5.
93 - Highlight more log messages.
94 - Highlight the Crunch reason only once. Previously the "crunch reason"
95 could also be highlighted when the URL contained a matching string.
96 The real crunch reason only occurs once per line, so there's no need
97 to continue looking for it after it has been found once.
98 While at it, add a comment with an example log line.
101 - Update BROWSER_VERSION and BROWSER_REVISION to 102.0
102 to match the User-Agent of the current Firefox ESR.
103 - Explicitly document that changing the 'Gecko token' is suspicious.
104 - Consistently use a lower-case 'c' as copyright symbol.
106 - Add 'aarch64' as Linux architecture.
107 - Add OpenBSD architecture 'arm64'.
108 - Stop using sparc64 as FreeBSD architecture.
109 It hasn't been supported for a while now.
113 - Makefile: Add a 'dok' target that depends on the 'error' target
114 to show the "You are not using GNU make or did nor run configure"
116 - configure: Fix --with-msan option.
117 Also (probably) reported by Andrew Savchenko.
119 - macOS build system:
120 - HTTPS inspection is enabled when building the macOS binary
121 using OpenSSL as TLS library.
124 - Add OpenSSL to the list of libraries that may be licensed under the
125 Apache 2.0 license in which case the linked Privoxy binary has to be
126 distributed under the GPLv3 or later.
127 - config: Fix the documented ca-directory default value
129 - Rebuild developer-manual and tidy with 'HTML Tidy for FreeBSD version 5.8.0'
130 - Update developer manual with new macOS packaging instructions.
132 *** Version 3.0.33 stable ***
133 - Security/Reliability:
134 - cgi_error_no_template(): Encode the template name to prevent
135 XSS (cross-site scripting) when Privoxy is configured to servce
136 the user-manual itself.
137 Commit 0e668e9409c. OVE-20211102-0001. CVE-2021-44543.
138 Reported by: Artem Ivanov
139 - get_url_spec_param(): Free memory of compiled pattern spec
141 Reported by Joshua Rogers (Opera) who also provided the fix.
142 Commit 652b4b7cb0. OVE-20211201-0003. CVE-2021-44540.
143 - process_encrypted_request_headers(): Free header memory when
144 failing to get the request destination.
145 Reported by Joshua Rogers (Opera) who also provided the fix.
146 Commit 0509c58045. OVE-20211201-0002. CVE-2021-44541.
147 - send_http_request(): Prevent memory leaks when handling errors
148 Reported by Joshua Rogers (Opera) who also provided the fix.
149 Commit c48d1d6d08. OVE-20211201-0001. CVE-2021-44542.
152 - handle_established_connection(): Skip the poll()/select() calls
153 if TLS data is pending on the server socket. The TLS library may
154 have already consumed all the data from the server response in
155 which case poll() and select() will not detect that data is
156 available to be read.
157 Fixes SF bug #926 reported by Wen Yue.
158 - continue_https_chat(): Update csp->server_connection.request_sent
159 after sending the request to make sure the latency is calculated
160 correctly. Previously https connections were not reused after
161 timeout seconds after the first request made on the connection.
162 - free_pattern_spec(): Don't try to free an invalid pointer
163 when unloading an action file with a TAG pattern while
164 Privoxy has been compiled without FEATURE_PCRE_HOST_PATTERNS.
165 Closes: SF patch request #147. Patch by Maxim Antonov.
166 - Adjust build_request_line() to create a CONNECT request line when
167 https-inspecting and forwarding to a HTTP proxy.
168 Fixes SF bug #925 reported by Wen Yue.
169 - load_config(): Add a space that was missing in a log message.
170 - read_http_request_body(): Fix two error messages that used an
172 - If the the response is chunk-encoded, ignore the Content-Length
173 header sent by the server.
174 Allows to load https://redmine.lighttpd.net/ with filtering enabled.
176 - General improvements:
177 - Allow to edit the add-header action through the CGI editor by
178 generalizing the code that got added with the suppress-tag action.
179 Closes SF patch request #146. Patch by Maxim Antonov.
180 - Add a CGI handler for /wpad.dat that returns a
181 Proxy Auto-Configuration (PAC) file.
182 Among other things, it can be used to instruct clients
183 through DHCP to use Privoxy as proxy.
184 For example with the dnsmasq option:
185 dhcp-option=252,http://config.privoxy.org/wpad.dat
186 Initial patch by Richard Schneidt.
187 - Don't log the applied actions in process_encrypted_request()
188 Log them in continue_https_chat() instead to mirror chat().
189 Prevents the applied actions from getting logged twice
190 for the first request on an https-inspected connection.
191 - OpenSSL generate_host_certificate(): Use config.privoxy.org as Common Name
192 Org and Org Unit if the real host name is too long to get accepted by OpenSSL.
193 Clients should only care about the Subject Alternative Name
194 anyway and we can continue to use the real host name for it.
195 Reported by Miles Wen on privoxy-users@.
196 - Establish the TLS connection with the client earlier and decide
197 how to route the request afterwards. This allows to change the
198 forwarding settings based on information from the https-inspected
199 request, for example the path.
200 - listen_loop(): When shutting down gracefully, close listening ports
201 before waiting for the threads to exit. Allows to start a second
202 Privoxy with the same config file while the first Privoxy is still
204 - serve(): Close the client socket as well if the server socket
205 for an inspected connection has been closed. Privoxy currently
206 can't establish a new server connection when the client socket
207 is reused and would drop the connection in continue_https_chat()
209 - Don't disable redirect checkers in redirect_url().
210 Disable them in handle_established_connection() instead.
211 Doing it in redirect_url() prevented the +redirect{} and
212 +fast-redirects{} actions from being logged with LOG_LEVEL_ACTIONS.
213 - handle_established_connection(): Slightly improve a comment.
214 - handle_established_connection(): Fix a comment.
215 - socks5_connect(): Fix indentation.
216 - handle_established_connection(): Improve an error message.
217 - create_pattern_spec(): Fix ifdef indentation.
219 - process_encrypted_request(): Improve a log message.
220 The function only processes request headers and there
221 may still be unread request body data left to process.
222 - chat(): Log the applied actions before deciding how to forward the request.
223 - parse_time_header(): Silence a coverity complaint when building without assertions.
224 - receive_encrypted_request_headers(): Improve a log message.
225 - mbedTLS get_ciphersuites_from_string(): Use strlcpy() instead of strncpy().
226 Previously the terminating NUL wasn't copied which resulted
227 in a compiler warning. This didn't cause actual problems as
228 the target buffer was initialized by zalloc_or_die() so the
229 last byte of the target buffer was NUL already.
230 Actually copying the terminating NUL seems clearer, though.
231 - Remove compiler warnings. "log_error(LOG_LEVEL_FATAL, ..."
232 doesn't return but apparently the compiler doesn't know that.
233 Get rid of several "this statement may fall through
234 [-Wimplicit-fallthrough=]" warnings.
235 - Store the PEM certificate in a dynamically allocated buffer
236 when https-inspecting. Should prevent errors like:
237 2021-03-16 22:36:19.148 7f47bbfff700 Error: X509 PEM cert len 16694 is larger than buffer len 16383
238 As a bonus it should slightly reduce the memory usage as most
239 certificates are smaller than the previously used fixed buffer.
241 - OpenSSL generate_host_certificate(): Fix two error messsages.
242 - Improve description of handle_established_connection()
243 - OpenSSL ssl_store_cert(): Translate EVP_PKEY_EC to a string.
244 - OpenSSL ssl_store_cert(): Remove pointless variable initialization.
245 - OpenSSL ssl_store_cert(): Initialize pointer with NULL instead of 0.
247 - Action file improvements:
248 - Disable fast-redirects for .microsoftonline.com/.
249 - Disable fast-redirects for idp.springer.com/.
250 - Disable fast-redirects for .zeit.de/zustimmung.
251 - Unblock adv-archiv.dfn-cert.de/.
252 - Block requests to eu-tlp01.kameleoon.eu/.
253 - Block requests to fpa-events.arstechnica.com/.
255 - Unblock adguard.com/.
257 - Privoxy-Log-Parser:
258 - Highlight 'Socket timeout 3 reached: http://127.0.0.1:20000/no-filter/chunked-content/36'.
259 - Improve documentation for inactivity-detection mode.
260 - Detect date changes when looking for inactivity.
261 - Add a --passed-request-statistics-threshold option
262 that can be set to get statistics for requests that
264 - Add a "inactivity detection" mode which can be useful
265 for debugging purposes.
266 - Bump version to 0.9.4.
267 - Only run print_intro() and print_outro() when syntax highlighting.
268 - Rephrase a sentence in the documentation.
269 - Highlight 'Client socket 7 is no longer usable. The server socket has been closed.'.
270 - Clarify --statistics output by explicitly mentioning that
271 the status codes sent by the server may differ from the ones
272 in "debug 512" messages.
273 - Fix typo in the --statistics output.
274 - Remove an unused variable.
275 - Highlight 'The peer notified us that the connection on socket 11 is going to be closed'.
277 - Privoxy-Regression-Test:
278 - Remove duplicated word in a comment.
280 - regression-tests.action:
281 - Add fetch test for http://p.p/wpad.dat.
282 - Bump for-privoxy-version to 3.0.33 which introduced the wpad.dat support.
283 - Add more tests for the '/send-banner' code.
284 - Add test for OVE-20210203-0001.
285 - Add a test for CVE-2021-20217.
288 - Bump generated Firefox version to 91 (ESR).
289 - Bump version to 1.2.3.
293 - configure: Bump SOURCE_DATE_EPOCH.
294 - GNUmakefile.in: Fix typo.
295 - configure: Add another warning in case --disable-pthread
296 is used while POSIX threads are available.
297 Various features don't even compile when not using threads.
298 - Add configure option to enable MemorySanitizer.
299 - Add configure option to enable UndefinedBehaviorSanitizer.
300 - Add configure option to enable AddressSanitizer.
302 - Add a configure option to disable pcre JIT compilation.
303 While JIT compilation makes filtering faster it can
304 cause false-positive valgrind complaints.
305 As reported by Gwyn Ciesla in SF bug 924 it also can
306 cause problems when the SELinux policy does not grant
307 Privoxy "execmem" privileges.
308 - configure: Remove obsolete RPM_BASE check.
310 - Windows build system:
311 - Update the build script to use mbed tls version 2.6.11.
312 - Update build script to use the final 8.45 pcre library.
313 - Put all the '--enable-xxx' options in the configure call together.
315 - macOS build system:
316 - The OSXPackageBuilder repository has been updated and
317 can be used to create macOS packages again.
320 - contacting: Remove obsolete reference to announce.sgml.
321 - contacting: Request that the browser cache is cleared before
322 producing a log file for submission.
323 - Sponsor FAQ: Note that Privoxy users may follow sponsor links
324 without Referer header set.
325 - newfeatures: Clarify that https inspection also allows to
326 filter https responses.
327 - developer-manual: Mention that announce.txt should be updated
328 when doing a release.
329 - config: Explicitly mention that the CGI pages disclosing the
330 ca-password can be blocked and upgrade the disclosure paragraphs
332 - Put all the requested debug options in the config file.
333 Section 11.1 of the Privoxy user manual lists all the debug
334 options that should be enabled when reporting problems or requesting support.
335 Make it easier for users to do the right thing by having all those
336 options present in the config.
337 - Update TODO list item #184 to note that WolfSSL support will
338 (hopefully) appear after the 3.0.34 release.
339 - Update max-client-connections's description.
340 On modern systems other than Windows Privoxy should
341 use poll() in which case the FD_SETSIZE value isn't
343 - Add a warning that the socket-timeout does not apply
344 to operations done by TLS libraries.
345 - Make documentation slightly less "offensive" for some people
346 by avoiding the word "hell".
348 *** Version 3.0.32 stable ***
350 - Security/Reliability:
351 - ssplit(): Remove an assertion that could be triggered with a
353 Commit 2256d7b4d67. OVE-20210203-0001. CVE-2021-20272.
354 Reported by: Joshua Rogers (Opera)
355 - cgi_send_banner(): Overrule invalid image types. Prevents a
356 crash with a crafted CGI request if Privoxy is toggled off.
357 Commit e711c505c48. OVE-20210206-0001. CVE-2021-20273.
358 Reported by: Joshua Rogers (Opera)
359 - socks5_connect(): Don't try to send credentials when none are
360 configured. Fixes a crash due to a NULL-pointer dereference
361 when the socks server misbehaves.
362 Commit 85817cc55b9. OVE-20210207-0001. CVE-2021-20274.
363 Reported by: Joshua Rogers (Opera)
364 - chunked_body_is_complete(): Prevent an invalid read of size two.
365 Commit a912ba7bc9c. OVE-20210205-0001. CVE-2021-20275.
366 Reported by: Joshua Rogers (Opera)
367 - Obsolete pcre: Prevent invalid memory accesses with an invalid
368 pattern passed to pcre_compile(). Note that the obsolete pcre code
369 is scheduled to be removed before the 3.0.33 release. There has been
370 a warning since 2008 already.
371 Commit 28512e5b624. OVE-20210222-0001. CVE-2021-20276.
372 Reported by: Joshua Rogers (Opera)
375 - Properly parse the client-tag-lifetime directive. Previously it was
376 not accepted as an obsolete hash value was being used.
377 Reported by: Joshua Rogers (Opera)
378 - decompress_iob(): Prevent reading of uninitialized data.
379 Reported by: Joshua Rogers (Opera).
380 - decompress_iob(): Don't advance cur past eod when looking
381 for the end of the file name and comment.
382 - decompress_iob(): Cast value to unsigned char before shifting.
383 Prevents a left-shift of a negative value which is undefined behaviour.
384 Reported by: Joshua Rogers (Opera)
385 - gif_deanimate(): Confirm that that we have enough data before doing
386 any work. Fixes a crash when fuzzing with an empty document.
387 Reported by: Joshua Rogers (Opera).
388 - buf_copy(): Fail if there's no data to write or nothing to do.
389 Prevents undefined behaviour "applying zero offset to null pointer".
390 Reported by: Joshua Rogers (Opera)
391 - log_error(): Treat LOG_LEVEL_FATAL as fatal even when --stfu is
392 being used while fuzzing.
393 Reported by: Joshua Rogers (Opera).
394 - Respect DESTDIR when considering whether or not to install
395 config files with ".new" extension.
396 - OpenSSL ssl_store_cert(): Fix two error messages.
397 - Fix a couple of format specifiers.
398 - Silence compiler warnings when compiling with NDEBUG.
399 - fuzz_server_header(): Fix compiler warning.
400 - fuzz_client_header(): Fix compiler warning.
401 - cgi_send_user_manual(): Also reject requests if the user-manual
402 directive specifies a https:// URL. Previously Privoxy would try and
403 fail to open a local file.
405 - General improvements:
406 - Log the TLS version and the the cipher when debug 2 is enabled.
407 - ssl_send_certificate_error(): Respect HEAD requests by not sending a body.
408 - ssl_send_certificate_error(): End the body with a single new line.
409 - serve(): Increase the chances that the host is logged when closing
411 - handle_established_connection(): Add parentheses to clarify an expression
412 Suggested by: David Binderman
413 - continue_https_chat(): Explicitly unset CSP_FLAG_CLIENT_CONNECTION_KEEP_ALIVE
414 if process_encrypted_request() fails. This makes it more obvious that the
415 connection will not be reused. Previously serve() relied on
416 CSP_FLAG_SERVER_CONTENT_LENGTH_SET and CSP_FLAG_CHUNKED being unset.
417 Inspired by a patch from Joshua Rogers (Opera).
418 - decompress_iob(): Add periods to a couple of log messages
419 - Terminate the body of the HTTP snipplets with a single new line
421 - configure: Add --with-assertions option and only enable assertions
423 - windows build: Use --with-brotli and --with-mbedtls by default and
424 enable dynamic error checking.
425 - gif_deanimate(): Confirm we've got an image before trying to write it
426 Saves a pointless buf_copy() call.
427 - OpenSSL ssl_store_cert(): Remove a superfluous space before the serial number.
429 - Action file improvements:
430 - Disable fast-redirects for .golem.de/
431 - Unblock requests to adri*.
432 - Block requests for trc*.taboola.com/
433 - Disable fast-redirects for .linkedin.com/
435 - Filter file improvements:
436 - Make the second pcrs job of the img-reorder filter greedy again.
437 The ungreedy version broke the img tags on:
438 https://bulk.fefe.de/scalability/.
440 - Privoxy-Log-Parser:
441 - Highlight a few more messages.
442 - Clarify the --statistics output. The shown "Reused connections"
443 are server connections so name them appropriately.
444 - Bump version to 0.9.3.
446 - Privoxy-Regression-Test:
447 - Add the --check-bad-ssl option to the --help output.
448 - Bump version to 0.7.3.
451 - Add pushing the created tag to the release steps in the developer manual.
452 - Clarify that 'debug 32768' should be used in addition to the other debug
453 directives when reporting problems.
454 - Add a 'Third-party licenses and copyrights' section to the user manual.
456 *** Version 3.0.31 stable ***
458 - Security/Reliability:
459 - Prevent an assertion from getting triggered by a crafted CGI request.
460 Commit 5bba5b89193fa. OVE-20210130-0001. CVE-2021-20217.
461 Reported by: Joshua Rogers (Opera)
462 - Fixed a memory leak when decompression fails "unexpectedly".
463 Commit f431d61740cc0. OVE-20210128-0001. CVE-2021-20216.
466 - Fixed detection of insufficient data for decompression.
467 Previously Privoxy could try to decompress a partly
468 uninitialized buffer.
470 *** Version 3.0.30 stable ***
473 - Check the actual URL for redirects when https inspecting requests.
474 Previously Privoxy would only check the path which resulted in
475 rewrite results being rejected as invalid URLs.
476 Reported by withoutname in #1736.
477 - Let the hide-referrer code tolerate Referer headers with https:// URLs.
478 Previously they would always be treated like a changed host.
479 - Use the https headers if the show-request handler is reached through
480 https://. Previously Privoxy would use the http headers which
481 may be empty on a reused connection.
482 - Make CGI_PREFIX protocol-relative when building with FEATURE_HTTPS_INSPECTION.
483 This unbreaks (at least) https://config.privoxy.org/client-tags whose
484 buttons would previously use a http:// URL resulting in browser warnings.
485 - Support using https-inspection and client-header-order at the same time.
486 Previously Privoxy would crash.
487 Reported by: Kai Raven
488 - Properly reject rewrites from http to https as they currently
489 aren't supported. Previously Privoxy would wait for the client
490 to establish an encrypted connection which obviously would not happen.
491 - When https inspection is enabled and Privoxy has been compiled with
492 FEATURE_GRACEFUL_TERMINATION (not recommended for production builds),
493 the TLS backend resources are free'd later on and only if no active
494 connections are left. Prevents crashes when exiting "gracefully" at the
496 - Let the uninstall target remove the config file even if DESTDIR
497 is set and properly announce the deletion of the configuration files.
499 - General improvements:
500 - Allow to rewrite the request destination for https-inspected
501 requests behind the client's back. The documentation already sort
502 of claimed that it was supported by not especially mentioning that
503 it didn't work for https-inspected requests.
504 Fixes SF bug #923 reported by withoutname.
505 - Add support for filtering client request bodies by using
506 CLIENT-BODY-FILTER filters which can be enabled with the
507 client-body-filter action.
508 Patch submitted by Maxim Antonov.
509 Sponsored by: Robert Klemme
510 - Add the new action suppress-tag{} which can be used to prevent
511 a tagger from adding a tag. Patch submitted by Maxim Antonov.
512 Sponsored by: Robert Klemme
513 - Gracefully handle existing website keys without matching certificates.
514 This can happen if Privoxy was previously running with an invalid
515 TLS configuration that didn't allow it to create a certificate.
516 - Recycle debug bit 4 for Tagging-related messages.
517 - Improve the message shown when the client-tags CGI page
518 is requested with no tags configured.
519 - Shorten the 'donate' and 'participate' links used by templates
520 using redirects. Currently the redirects lead to the FAQ entries
521 but in the future we may want to relocate the content and using
522 redirects makes this more convenient.
523 - Log an error when a PCRE-HOST-PATTERN is used with
524 FEATURE_PCRE_HOST_PATTERNS disabled. Don't treat this a
525 fatal error so the regression tests can be used with and
526 without FEATURE_PCRE_HOST_PATTERNS.
527 - The code compiles with older C compilers again.
528 - The chdir() return code is checked to fix a compiler warning.
529 - The packages feed has been removed from the source tarball.
530 It's usually out of date when the source tarball is generated
532 - Fixed harmless compiler warnings from GCC9 with -D_FORTIFY_SOURCE=2.
533 - windows: Remove obsolete '$(DEST)/doc/images' target.
534 - windows: Install the images referenced in the user manual.
535 - Remove obsolete 'gnu_regex.@OBJEXT@' target.
536 - When installing from the GNUMAkefile, don't create an 'images'
537 directory which is no longer used. The images were relocated to
538 the user-manual directory years ago.
539 - Add new FEATURES to the show-status page and resort list.
540 - Remove unused variable in the OpenSSL-specific code.
541 - Update bug tracker URL in cgi_error_unknown().
542 - Saved a couple of memory allocations when sorting client headers.
543 - Improved a couple of error messages.
544 - Saved memory allocations when using OpenSSL and checking if a
546 - The configure script will bail out if OpenSSL and mbedTLS are
547 enabled at the same time.
548 - Log a message right before exiting gracefully.
549 - A couple of structures have been rearranged to require slightly
551 - When https inspection is enabled and the certificate is invalid
552 the error message is now sent with status code 403 instead of 200.
553 - The Slackware rc script template has been renamed to
554 slackware/rc.privoxy.in to silence complaints when building
556 - When building with MbedTLS support, mbedtls_md5_ret() is used
557 instead of mbedtls_md5() which is deprecated and causes a warning
560 - Action file improvements:
561 - Block requests to eu-tlp03.kameleoon.com/.

577 - Filter file improvements:
578 - A allow-autocompletion filter has been added which changes
579 autocomplete="off" to "on" on input fields to allow autocompletion.
580 Requested by Jamie Zawinski in #370.
581 Filter based on a submission by Aaron Linville.
582 - Added an imdb filter.
583 - Added a sourceforge filter that reduces the amount of ads
584 for proprietary software.
585 - Added a github filter that removes the annoying "Sign-Up"
586 banner and the Cookie disclaimer.
587 - Removed a duplicated pcrs command from the js-annoyances filter.
588 - The crude-parental filter now provides a short reason when blocking,
589 inserts a link to Privoxy's webinterface and adds a new line at
590 the end of the generated page.
592 - Privoxy-Log-Parser:
593 - Highlight a few more messages.
594 - Add a handler for tagging messages.
595 - Properly deal with 'Certificate error' crunches
596 Previously the error description was highlighted as 'host'.
597 - Log truncated LOG_LEVEL_CLF messages more gracefully
598 and note that the statistics will be imprecise.
599 - Fixed perldoc typo.
600 - Bump version to 0.9.2.
602 - Privoxy-Regression-Test:
603 - Use http://127.0.0.1:8118/ as default Privoxy address
604 unless http_proxy is set through the environment.
605 - Add a --privoxy-cgi-prefix option that specifies the prefix
606 to use when building URLs that are supposed to reach Privoxy's
607 CGI interface. If it's not set, http://p.p/ is used, which is
608 supposed to work with the default Privoxy configuration.
609 If Privoxy has been built with FEATURE_HTTPS_INSPECTION enabled,
610 and if https inspection is activated with the +https-inspection
611 action, this option can be used with "https://p.p/" provided the
612 system running Privoxy-Regression-Test has been configured to
613 trust the certificate used by Privoxy.
614 Note that there are currently two tests in the official
615 regression-tests.action file that are expected to fail
616 when using "https://p.p/" as privoxy-cgi-prefix.
617 - Skip the connection-established response in get_status_code()
618 when looking for the status code with a CGI prefix
619 that starts with https://. We care about the status code
620 sent by the impersonated web server.
621 - Use --proxy-header when using a CGI prefix with https://
622 and a "Host:" header.
623 - Allow '|' in tokens and values to allow tag patterns like
624 "TAG:^(application|text)/(x-)?javascript$".
625 - When get_cgi_page_or_else() fails, include the URL of the
626 requested page in the log message.
627 - Added a --check-bad-ssl option that can be used to verify that
628 Privoxy detects certificate problems when accessing the test
629 sites from badssl.com.
630 - Bumped version to 0.7.2
633 - Update example output.
634 - Recommend the use of the https-inspection action in the documentation.
635 - Upgrade a couple of URLs to https://.
636 - Add ElectroBSD to the list of operating systems.
637 - Bumped generated Firefox version to 78 (ESR).
638 - Bumped version to 1.2.2.
640 - User documentation:
641 - Remove reference to 'How to Report Bugs Effectively'.
642 It was only rendered as text without URL in the README anyway
643 and there's no indication that users read it ...
644 - Let the dok-readme target fix the location embedded into the
645 README file. This used to be done by CVS but since the git migration
646 it has to be done through other means.
647 - Remove 'experimental' warning for client-specific-tag-related directives.
648 They seem to work reliably and there is no obvious reason
649 why we would change the syntax in the near future.
650 - Describe how to check if Privoxy has been built with
651 FEATURE_HTTPS_INSPECTION.
652 - Add a link to the trusted-cas-file documentation
653 that explains how the user can create the file herself.
654 - Don't explicitly mention the license for the code coming from
655 'Anonymous Coders' and Junkbusters. It's obviously licensed under
656 the GNU GPL like the rest of Privoxy or we wouldn't be allowed to
658 - Update the +hide-user-agent example with uagen output.
659 - Slightly improve the wording of the ca-key-file documentation.
660 - Explicitly mention Windows 10 as supported so search engines and
661 users looking for it can find it.
662 - Import a bunch of contributors from the ChangeLog.
663 - Remove obsolete doc/gpl.html.
664 - Upgrade a couple of links to https://.
665 - Don't prefer the SourceForge patch tracker over the
666 privoxy-devel mailing list. While at it, link to the
667 SourceForge patch tracker.
668 - Mention http-inspection in the 'my browser warns me about
669 unauthenticated content' FAQ entry.
670 - Simplify the 'Is there is a license or fee?' FAQ entry.
671 - Add another +redirect{} example.
672 - Explicitly mention that interested sponsors should include
673 the link target in their first mail.
674 - Clarify that only Privoxy team members can object to new sponsors
675 and link to the list of current team members.
676 - Note that sponsor URLs may not contain keyword spam.
677 - Garbage collect doc/webserver/images which isn't referenced anymore.
678 - Update the method to reach the proxy settings in Firefox.
679 - Update proxy_setup.jpg description to refer to Firefox.
680 - Regenerate proxy_setup.jpg with a more recent Firefox (78.0).
681 - Regenerate files-in-use.jpg without obsolete standard.action
682 with modern colors and a slightly better quality.
683 - Update URL to the actionsfile tracker.
684 - Update a support request URL.
685 - Rephrase the 'Can Privoxy run as service' FAQ entry and
686 remove an obsolete paragraph.
687 - Let the 'Where can I get updated Actions Files?' entry link to
688 the gitweb version of default.action.master.
689 - Update a link to the default.action file.
690 - Update URLs for trackers and mailing lists.
691 - Replace CVS reference with git.
692 - Mention regression-tests.action in the config file.
693 - Explicitly mention in the config file that access to the
694 CA key should be limited to Privoxy.
695 - List more client-specific-tag examples for inspiration.
696 - Add additional headers to the client-header-order example.
697 - Note that actions aren't updated after rewrites.
698 - Explicitly mention that upgrading from http to https with
699 a client-header filter is not supported
700 - Note that protocol and host have to be added when rewriting
701 the destination host for https-inspected requests.
702 - Explicitly mention that the CA key is used to sign certificates.
703 - Put openssl command in 'command' tags.
704 - The man page has been moved from section 1 to man section 8.
707 - Flesh out the build instructions for Debian.
708 - Remove the packaging instructions for RPM-based systems.
709 They don't work and we don't release RPM packages anymore anyway.
710 - Remove the packaging instructions for Solaris.
711 They don't work and we don't release Solaris packages anymore anyway.
712 - Update the suggested subject for the announce mails.
713 - Update upload instructions.
714 ftp://upload.sourceforge.net is no longer functional.
715 - Remove a couple of package-dependent upload instructions
716 that don't actually work.
717 - Remove 'cd current' that no longer works.
718 - Add regression-tests.action to the list of files that should be installed.
719 - Stop claiming that there are text versions of the manuals.
720 We stopped building them in 2008 (9ed36a3c5e6f12).
721 - Note that the 'webserver' target creates the link needed for the user-manual.
722 - Suggest to use the master branch as reference when creating
723 the ChangeLog so the steps work when the current branch differs
724 from master which is likely as the developer manual
725 suggests to use a local branch for development.
726 - Add the -s flag to the suggested 'git tag' command. We prefer signed tags.
727 - Mention that merges into 'master' should be avoided.
728 - Add git commands that should result in a merge-free history.
729 - Mention Privoxy-Regression-Test.
730 - Add a section id to reduce link churn.
731 - Recommend the dok-tidy target when building docs for the webserver.
732 - Add another plug for the privoxy-devel mailing list.
733 - Let the intro link the copyright section in the user manual instead
734 of giving an incomplete summary of the license status.
735 - Clarify that the webserver target uploads to the SourceForge webserver.
736 - Mark the documentation for the Mac OS X installers as out of date and
737 change the SCM name back to CVS.
738 - Fix the location of the installer modules for Mac OS X.
739 They are not actually available through git (yet).
740 - Don't speak of Privoxy version 3 in the past tense.
741 - Update the list of programs required for the release process.
742 - Update description of the webserver target which uses ssh, not scp.
743 - Remove obsolete reference to config.new.
746 - Add another hide-referrer{conditional-block} test.
747 - Add another hide-referrer{conditional-forge} test.
748 - Fix a hide-referrer{conditional-forge} test
749 that expected an acceptable header to be forged.
750 - Fix a hide-referrer{conditional-block} test
751 that expected an acceptable Referer to be removed.
752 - Explain why the "Set Header = Host: whatever.example.org" test is
753 expected to fail when using a CGI prefix that starts with "https://".
754 - Explain why a connection-sharing test is known to fail
755 when using "https://p.p/" as CGI prefix.
756 - Add a link to Privoxy-Regression-Test to regression-tests.action
757 in case it isn't packaged.
758 - Add regression tests for pcre host patterns.
759 - Fixed a regression test that is executed when
760 FEATURE_GRACEFUL_TERMINATION is enabled.
762 - Privoxy infrastructure:
763 - Import a Privoxy logo for the website.
764 - Update Tor onion service to HiddenServiceVersion 3.

804 - General improvements:
805 - Added experimental https inspection support which allows to filter
806 https traffic. To enable it, install MbedTLS and configure with
807 --with-mbedtls, or install OpenSSL or LibreSSL and configure
809 Afterwards configure the directives in section 7 of the
810 config file and enable the +https-inspection action.
811 Initial MbedTLS-based code contributed by Vaclav Svec,
812 initial OpenSSL support contributed by Maxim Antonov.
813 With help from Nedzad Hrnjica and Ho+ Ho+ Ho+.
814 Integration and improvements sponsored by Robert Klemme.
815 - pcrs: Request JIT compilation if it's supported and
816 the filter isn't dynamic. This can speed up filtering.
817 - Added support for Brotli decompression.
818 Sponsored by: Robert Klemme
819 - Added FEATURE_EXTENDED_STATISTICS to gather statistics for
820 block reasons and filter executions. To enable it, configure
821 with --enable-extended-statistics and visit
822 http://config.privoxy.org/show-status.

824 - Use the IP_FREEBIND socket option, if defined. This allows
825 Privoxy to bind to not-yet assigned IP addresses which is
826 useful in failover environments.
827 Patch by Sam Varshavchik.
828 - Allow to use extended host patterns and vanilla host patterns
829 at the same time by prefixing extended host patterns with
830 "PCRE-HOST-PATTERN:". To enable this, configure with
831 --enable-pcre-host-patterns.

833 - Added "Cross-origin resource sharing" (CORS) support.
834 This allows to access Privoxy's CGI interface via JavaScript from
835 another domain (white-listed with the new cors-allowed-origin directive).
836 Based on a patch by Nedzad Hrnjica.

844 - Fixed handling of filters with "split-large-forms 1"
845 when using the CGI editor.
846 Reported by withoutname in #921.
847 - Better detect a mismatch of connection details when
848 figuring out whether or not a connection can be reused.
849 - Don't send a "Connection failure" message instead of the
850 "DNS failure" message.
851 Sponsored by: Robert Klemme
852 - Let LOG_LEVEL_REQUEST log all requests. Previously unencrypted
853 requests were only logged with LOG_LEVEL_REQUEST when they weren't
854 crunched (in which case they were logged with LOG_LEVEL_CRUNCH).
855 This was documented behaviour, but logging all requests seems more useful.
856 - Fixed locking around localtime() and gmtime().
857 - Removed OS/2 support. We haven't provided OS/2 packages in years,
858 it complicated the code and it depended on a fallback snprintf()
859 implementation which is GPLv2 only.
860 - Remove the fallback snprintf() implementation
861 Now that OS/2 support is gone we no longer need it.
862 - Fixed a bunch of format specifiers log messages.
863 - Added a missing apostrophe in the 'More Privoxy' menu.
864 - Explicitly prevent use of FEATURE_CONNECTION_SHARING
865 without FEATURE_CONNECTION_KEEP_ALIVE. It makes no sense
866 and does not compile anyway.

879 - Remove SourceForge references in copyright headers.
880 - Upgrade a bunch of links to the homepage to https://.
881 - Add 'no-brotli-accepted' filter which prevents the
882 use of Brotli compression.
883 - Changed license for pcrs to GPLv2+ after getting the
884 permission from Andreas. This allows to redistribute
885 Privoxy under the GPLv3 which is required when linking
886 to future mbedTLS versions which are expected to be
887 licensed under the Apache 2.0 license only.
888 - Updated a bunch of tests that have to expect status code 403
889 now after r1.168/070e904afa5.
890 - Lowercase the host name in the request line.
891 - Only set SOURCE_DATE_EPOCH if it's not already set so
892 distributions can overwrite it through the environment.
894 - Documentation changes:
895 - Explain that Privoxy has to be distributed under the
896 GPLv3 (or later) when linked with an MbedTLS version
897 that is licensed under the Apache 2.0 license.
898 - Import the GNU GPLv3 and include it the user manual.
899 - Clarify FEATURE_FORCE_LOAD's description. It allows to bypass
900 blocking not filtering and only does it if blocks aren't enforced.

906 - FAQ: Add a link to the TODO list.
907 - FAQ: Change the sponsor amounts to USD slightly rounding the
908 converted amounts up to get simple numbers.
909 Receiving USD is apparently easier for SPI and SPI is
910 preferred by sponsors as they can send invoices.

916 - Remove an obsolete comment
918 - Config file changes:
919 - Change the suggested default-server-timeout to 5 to match the
920 suggested keep-alive-timeout. Otherwise using the defaults would
921 result in Privoxy reducing the default-server-timeout and logging

977 transferred excluding HTTP headers.
978 - Get with the program and expect all requests to be logged with LOG_LEVEL_REQUEST.
979 It's no longer necessary to count both LOG_LEVEL_REQUEST and
980 LOG_LEVEL_CRUNCH messages to get the total number of requests.
981 - Leverage the LOG_LEVEL_CLF message to gather statistics that where
982 previously taken from LOG_LEVEL_HEADER lines. This results in less
983 confusing results if https inspection is enabled in which case there
984 are two LOG_LEVEL_HEADER lines with request lines.
985 Sponsored by: Robert Klemme
986 - Properly highlight the filter results message. Previously a brace got lost.
987 - Prefer the number of CLF lines to get the total number of requests
988 as it works with older Privoxy versions as well.
990 - Privoxy-Regression-Test:
991 - Turn curl's globbing mode off so we can allow more characters in URLs.
992 - Allow '[' and ']' in URLs.
993 - Include the action file when complaining about missing Sticky Actions.
994 - Fix a sentence in the documentation.
995 - Bump version to 0.7.1

1008 *** Version 3.0.28 stable ***
1010 - Bug fixes for regressions in 3.0.27:
1011 - Fixed misplaced parentheses.
1012 Reported by David Binderman.
1013 - Changed two regression tests to depend on config directive
1014 enable-remote-toggle instead of FEATURE_TOGGLE.
1016 *** Version 3.0.27 stable ***
1018 - General improvements:
1019 - Add a receive-buffer-size directive which can be used to
1020 set the size of the previously statically allocated buffer
1021 in handle_established_connection().
1022 Increasing the buffer size increases Privoxy's memory usage but
1023 can lower the number of context switches and thereby reduce the
1024 CPU usage and potentially increase the throughput.
1025 This is mostly relevant for fast network connections and
1026 large downloads that don't require filtering.
1027 Sponsored by: Robert Klemme
1028 - Add a listen-backlog directive which specifies the backlog
1029 value passed to listen().
1030 Sponsored by: Robert Klemme
1031 - Add an enable-accept-filter directive which allows to
1032 toggle accept filter support at run time when compiled
1033 with FEATURE_ACCEPT_FILTER support.
1034 It makes testing more convenient and now that it's
1035 optional we can emit an error message if enabling
1036 the accept filter fails.
1037 Sponsored by: Robert Klemme
1038 - Add a delay-response{} action.
1039 This is useful to tar pit JavaScript requests that
1040 are endlessly retried in case of blocks. It can also
1041 be used to simulate a slow Internet connection.
1042 Sponsored by: Robert Klemme
1043 - Add a 'trusted-cgi-referrer' directive.
1044 It allows to configure another page or site that can be used
1045 to reach sensitive CGI resources.
1046 Sponsored by: Robert Klemme
1047 - Add a --fuzz mode which exposes Privoxy internals to input
1048 from files or stdout.
1049 Mainly tested with American Fuzzy Lop. For details see:
1050 https://www.fabiankeil.de/talks/fuzzing-on-freebsd/
1051 This work was partially funded with donations and done
1052 as part of the Privoxy month in 2015.
1053 - Consistently use the U(ngreedy) flag in the 'img-reorder' filter.
1054 - listen_loop(): Reuse a single thread attribute object
1055 The object doesn't change and creating a new one for
1056 every thread is a waste of (CPU) time.
1057 Sponsored by: Robert Klemme
1058 - Free csp resources in the thread that belongs to the csp instead
1059 of the main thread which has enough on its plate already.

1061 - Improve 'socket timeout reached' message.
1062 Log the timeout that was triggered and downgrade the
1063 log level to LOG_LEVEL_CONNECT to reduce the log noise
1064 with common debug settings.
1065 The timeout isn't necessary the result of an error and
1066 usually merely indicates that Privoxy's socket timeout
1067 is lower than the relevant timeouts used by client and
1069 Sponsored by: Robert Klemme
1070 - Explicitly taint the server socket in case of CONNECT requests.
1071 This doesn't fix any known problems, but makes
1072 some log messages less confusing.
1073 - Let write_pid_file() terminate if the pid file can't be opened.
1074 Logging the issue at info level is unlikely to help.
1075 - log_error(): Reduce the mutex-protected area by not using a
1076 heap-allocated buffer that is shared between all threads.
1077 This increases performance and reduces the latency with
1078 verbose debug settings and multiple concurrent connections.
1079 Sponsored by: Robert Klemme
1080 - Let zalloc() use calloc() if it's available.
1081 In some situations using calloc() can be faster than
1082 malloc() + memset() and it should never be slower.
1083 In the real world the impact of this change is not
1084 expected to be noticeable.
1085 Sponsored by: Robert Klemme
1086 - Never use select() when poll() is available.
1087 On most platforms select() is limited by FD_SETSIZE while
1088 poll() is not. This was a scaling issue for multi-user setups.
1089 Using poll() has no downside other than the usual risk
1090 that code modifications may introduce new bugs that have
1091 yet to be found and fixed.
1092 At least in theory this commit could also reduce the latency
1093 when there are lots of connections and select() would use
1094 "bit fields in arrays of integers" to store file descriptors.
1095 Another side effect is that Privoxy no longer has to stop
1096 monitoring the client sockets when pipelined requests are
1097 waiting but can't be read yet.
1098 This code keeps the select()-based code behind ifdefs for
1099 now but hopefully it can be removed soonish to make the

1102 - Add a 'reproducible-tarball-dist' target.
1103 It's currently separate from the "tarball-dist" target
1104 because it requires a tar implementation with mtree spec
1106 It's far from being perfect and does not enforce a
1107 reproducible mode, but it's better than nothing.
1108 - Use arc4random() if it's available.
1109 While Privoxy doesn't need high quality pseudo-random numbers
1110 there's no reason not to use them when we can and this silences
1111 a warning emitted by code checkers that can't tell whether or not
1112 the quality matters.
1113 - Show the FEATURE_EXTERNAL_FILTERS status on the status page.
1114 Better late than never. Previously a couple of tests weren't
1115 executed as Privoxy-Regression-Test couldn't detect that the
1116 FEATURE_EXTERNAL_FILTERS dependency was satisfied.
1117 - Ditch FEATURE_IMAGE_DETECT_MSIE.
1118 It's an obsolete workaround we inherited from Junkbuster
1119 and was already disabled by default.
1120 Users that feel the urge to work around issues with
1121 image requests coming from an Internet Explorer version
1122 from more than 15 years ago can still do this using tags.
1123 - Consistently use strdup_or_die() instead of strdup() in
1124 cases where allocation failures aren't expected.
1125 Using strdup_or_die() allows to remove a couple of explicit
1126 error checks which slightly reduces the size of the binary.
1127 - Insert a refresh tag into the /client-tags CGI page when
1128 serving it while a client-specific tag is temporarily enabled.
1129 This makes it less likely that the user ends up
1130 looking at tag state that is out of date.
1131 - Use absolute URLs in the client-tag forms.
1132 It's more consistent with the rest of the CGI page
1133 URLs and makes it more convenient to copy the forms
1135 - cgi_error_disabled(): Use status code 403 and an appropriate response line
1136 - Use a dedicated CGI handler to deal with tag-toggle requests
1137 As a result the /client-tags page is now safe to reach without
1138 trusted Referer header which makes bookmarking or linking to
1140 Finally, refreshing the /client-tags page to show the
1141 current state can no longer unintentionally repeat the
1142 previous toggle request.
1143 - Don't add a "Connection" header for CONNECT requests.
1144 Explicitly sending "Connection: close" is not necessary and
1145 apparently it causes problems with some forwarding proxies
1146 that will close the connection prematurely.
1147 Reported by Marc Thomas.
1148 - Fix compiler warnings.
1151 - rfc2553_connect_to(): Properly detect and log when poll()
1152 reached the time out. Previously this was logged as:
1153 Could not connect to [...]: No error: 0.
1154 which isn't very helpful.
1155 Sponsored by: Robert Klemme
1156 - add_tag_for_client(): Set time_to_live properly.
1157 Previously the time_to_live was always set for the first tag.
1158 Attempts to temporarily enable a tag would result in enabling
1159 it permanently unless no tag was enabled already.
1160 - Revert r1.165 which didn't perform as advertised.
1161 While the idea was to use "https:// when creating links
1162 for the user manual on the website", the actual effect
1163 was to use "https://" when Privoxy was supposed to serve
1164 the user manual itself.
1165 Reported by Yossi Zahn on Privoxy-devel@.
1166 - socks5_connect(): Fail in case of unsupported address types.
1167 Previously they would not be detected right away and
1168 Privoxy would fail later on with an error message that
1169 didn't make it obvious that the problem was socks-related.
1170 So far, no such problems have actually been reported.
1171 - socks5_connect(): Properly deal with socks replies that
1172 contain IPv6 addresses.
1173 Previously parts of the reply were left unread and
1174 later on treated as invalid HTTP response data.
1175 Fixes #904 reported by Danny Goossen who also provided
1176 the initial version of this patch.
1178 - Action file improvements:
1179 - Unblock 'msdn.microsoft.com/'.
1180 It (presumably) isn't used to serve the kind of ads Privoxy should
1181 block by default but happens to serve lots of pages with URLs that
1182 are likely to result in false positives.
1183 Reported by bugreporter1694 in AF#939.
1184 - Disable gif deanimation for requests tagged with CSS-REQUEST.
1185 The action will ignore content that isn't considered text
1186 anyway and explicitly disabling it makes this more obvious
1187 if "action" debugging (debug 65536) is enabled while
1188 "gif deanimation" debugging (debug 256) isn't.
1189 - Explicitly disable HTML filters for requests with CSS-REQUEST tag.
1190 The filters are unlikely to break CSS files but executing
1191 them without (intentionally) getting any hits is a waste of
1192 cpu time and makes the log more noisy when running with
1194 - Unblock 'adventofcode.com/'.

1202 - Privoxy-Log-Parser:
1203 - Don't gather host and resource statistics if they aren't requested.
1204 While the performance impact seems negligible this significantly
1205 reduces the memory usage if there are lots of requests.

1213 While privoxy-log-parser was supposed to detect this already,

1215 somewhat confusing anyway.

1219 - Documentation improvements:
1220 - Refer to the git sources instead of CVS.
1221 - Use GNU/Linux when referring to the OS instead of the kernel.
1222 - Add FAQ entry for what to do if editing the config file is access denied.
1223 - Add brief HTTP/2 FAQ.
1224 - Add a small fuzzing section to the developer documentation.
1225 - Add a client-header-tagger{client-ip-address} example.
1226 - Stop suggesting that Privoxy is an anonymizing proxy.
1227 The term could lead to Privoxy users overestimating
1228 what it can do on its own (without Tor).
1229 - Make it more obvious that SPI accepts Paypal, too.
1230 Currently most donations are made through the Paypal account
1231 managed by Zwiebelfreunde e.V. and a more even distribution
1233 - Suggest to log applying actions as well when reproducing problems.
1234 - Explicitly mention that Privoxy binaries are built by individuals
1235 on their own systems. Buyer beware!
1236 - Mention the release feed on the homepage.
1237 - Remove a mysterious comment with a GNU FDL link as it isn't
1238 useful and could confuse license scanners.
1239 In May 2002 it was briefly claimed that "this document" was covered
1240 by the GNU FDL. The commit message (r1.5) doesn't explain the motivation
1241 or whether all copyright holders were actually asked and agreed to the
1242 declared license change.
1243 It's thus hard to tell whether or not the license change was legit,
1244 but luckily two days later the "doc license" was "put" "back to GPL"
1246 At the same time the offending comment with a link to the FDL
1247 (not the GPL) was added for no obvious reason.
1248 Now it's gone again.
1251 - Bump for-privoxy-version to 3.0.27 as we now rely on untrusted
1252 CGI request being rejected with status code 403 (instead of 200).
1253 - Update test for /send-stylesheet and add another one
1256 - Consistently use https:// when linking to the Privoxy website.
1257 - Remove SourceForge references in Copyright header.
1258 - Remove a couple of SourceForge references in a comment.
1259 While at it, fix the grammar.
1260 - Move the site-specific documentation block before the generic one.
1261 While most Privoxy installations don't have a site-specific
1262 documentation block, in cases were it exists it's likely to
1263 be more relevant than the generic one.
1264 Showing it first makes it less likely that users stop reading
1265 before they reach it, especially on pages that don't fit on
1268 - Build system improvements:
1269 - Prefer openjade to jade. On some systems Jade produces
1270 HTML with unescaped ampersands in URLs.
1271 - Prefer OpenSP to SP to be consistent.
1272 - Have Docbook generated HTML files be straight ASCII.
1273 Dealing with a mixture of ISO-8859 and UTF-8 files is problematic.
1274 - Echo the filename to stderr for 'make dok-tidy'.
1275 Make it a bit easier to find errors in docbook generated HTML.
1276 - Warn when still using select().
1277 - Warn when compiling without calloc().
1278 - Make it more obvious that the --with-fdsetsize configure switch
1279 is pointless if poll() is available.
1280 - Remove support for AmigaOS.
1281 - Update windows build system to use supported software.
1282 The cygwin gcc -mno-cygwin option is no longer supported, so
1283 convert the windows build system to use the cygwin cross-compiler
1284 to build "native" code.
1285 - Add --enable-static-linking option for configure
1286 does the same thing as LDFLAGS=-static; ./configure
1287 but nicer than mixing evars and configure options.
1289 *** Version 3.0.26 stable ***
1292 - Fixed crashes with "listen-addr :8118" (SF Bug #902).
1293 The regression was introduced in 3.0.25 beta and reported
1294 by Marvin Renich in Debian bug #834941.
1296 - General improvements:
1297 - Log when privoxy is toggled on or off via cgi interface.
1298 - Highlight the "Info: Now toggled " on/off log message
1299 in the Windows log viewer.
1300 - Highlight the loading actions/filter file log message
1301 in the Windows log viewer.
1302 - Mention client-specific tags on the toggle page as a
1303 potentionally more appropriate alternative.
1305 - Documentation improvements:

1307 The downloads are available from the website now.
1309 - Remove obsolete reference to mailing lists hosted at SourceForge.
1310 - Update the "Before the Release" section of the developer manual.
1312 - Infrastructure improvements:
1313 - Add perl script to generate an RSS feed for the packages
1314 Submitted by "Unknown".
1316 - Build system improvements:
1317 - strptime.h: fix a compiler warning about ambiguous else.
1318 - configure.in: Check for Docbook goo on the BSDs as well.
1319 - GNUMakefile.in: Let the dok-user target remove temporary files.
1321 *** Version 3.0.25 beta ***
1324 - Always use the current toggle state for new requests.
1325 Previously new requests on reused connections inherited
1326 the toggle state from the previous request even though
1327 the toggle state could have changed.
1328 Reported by Robert Klemme.
1329 - Fixed two buffer-overflows in the (deprecated) static
1330 pcre code. These bugs are not considered security issues
1331 as the input is trusted.
1332 Found with afl-fuzz and ASAN.
1334 - General improvements:
1335 - Added support for client-specific tags which allow Privoxy
1336 admins to pre-define tags that are set for all requests from
1337 clients that previously opted in through the CGI interface.
1338 They are useful in multi-user setups where admins may
1339 want to allow users to disable certain actions and filters
1340 for themselves without affecting others.
1341 In single-user setups they are useful to allow more fine-grained
1342 toggling. For example to disable request blocking while still
1343 crunching cookies, or to disable experimental filters only.
1344 This is an experimental feature, the syntax and behaviour may
1345 change in future versions.

1356 and after 2038 are expected to be handled properly.
1357 This is mainly useful for Privoxy-Regression-Test but could
1358 also come handy when dealing with time-related support requests.

1366 - Action file improvements:
1367 - Filtering is disabled for Range requests to let download resumption
1368 and Windows updates work with the default configuration.

1377 mention the archives at SF in the contacting section
1379 - Note that the templates should be adjusted if Privoxy is
1380 running as intercepting proxy without getting all requests.
1381 - A bunch of links were converted to https://.
1382 - Rephrase onion service paragraph to make it more obvious
1383 that Tor is involved and that the whole website (and not
1384 just the homepage) is available as onion service.
1385 - Streamline the "More information" section on the homepage further
1386 by additionally ditching the link to the 'See also' section
1387 of the user manual. The section contains mostly links that are
1388 directly reachable from the homepage already and the rest is
1389 not significant enough to get a link from the homepage.
1390 - Change the add-header{} example to set the DNT header
1391 and use a complete section to make copy and pasting
1393 Add a comment to make it obvious that adding the
1394 header is not recommended for obvious reasons.
1395 Using the DNT header as example was suggested by
1397 - Streamline the support-and-service template
1398 Instead of linking to the various support trackers
1399 (whose URLs hopefully change soon), link to the

1404 - FAQ: Explain why 'ping config.privoxy.org' is not expected
1405 to reach a local Privoxy installation.
1406 - Note that donations done through Zwiebelfreunde e.V. currently
1407 can't be checked automatically.
1408 - Updated section regarding starting Privoxy under OS X.
1409 - Use dedicated start instructions for FreeBSD and ElectroBSD.
1410 - Removed release instructions for AIX. They haven't been working
1411 for years and unsurprisingly nobody seems to care.
1412 - Removed obsolete reference to the solaris-dist target.
1413 - Updated the release instructions for FreeBSD.
1414 - Removed unfinished release instructions for Amiga OS and HP-UX 11.
1415 - Added a pointer to the Cygwin Time Machine for getting the last release of
1416 Cygwin version 1.5 to use for building Privoxy on Windows.
1417 - Various typos have been fixed.
1419 - Infrastructure improvements:
1420 - The website is no longer hosted at SourceForge and
1421 can be reached through https now.
1422 - The mailing lists at SourceForge have been deprecated,
1423 you can subscribe to the new ones at: https://lists.privoxy.org/
1424 - Migrating the remaining services from SourceForge is
1425 work in progress (TODO list item #53).
1427 - Build system improvements:

1429 with the intent to change the maximum number of client
1430 connections Privoxy can handle. Only works with some libcs.

1435 - Include tools in the generic distribution.
1436 - Let the gen-dist target work in cwds other than current.
1437 - Sort find output that is used for distribution tarballs
1438 to get reproducible results.
1439 - Don't add '-src' to the name of the tar ball generated by the
1440 gen-dist target. The package isn't a source distribution but a
1442 While at it, use a variable for the name to reduce the chances
1443 that the various references get out of sync and fix the gen-upload
1444 target which was looking in the wrong directory.

1454 change the default level by a given value.
1455 This directive affects all tests located after it until the end
1456 of the file or a another "Default level offset" directive is reached.

1481 and the error message incorrectly blamed the server.
1482 Fixes #1686 reported by Peter Müller and G4JC.
1483 - Fixed buffer scaling in execute_external_filter() that could lead
1484 to crashes. Submitted by Yang Xia in #892.
1485 - Fixed crashes when executing external filters on platforms like
1486 Mac OS X. Reported by Jonathan McKenzie on ijbswa-users@.
1487 - Properly parse ACL directives with ports when compiled with HAVE_RFC2553.
1488 Previously the port wasn't removed from the host and in case of
1489 'permit-access 127.0.0.1 example.org:80' Privoxy would try (and fail)
1490 to resolve "example.org:80" instead of example.org.
1491 Reported by Pak Chan on ijbswa-users@.
1492 - Check requests more carefully before serving them forcefully
1493 when blocks aren't enforced. Privoxy always adds the force token
1494 at the beginning of the path, but would previously accept it anywhere
1495 in the request line. This could result in requests being served that
1496 should be blocked. For example in case of pages that were loaded with
1497 force and contained JavaScript to create additionally requests that
1498 embed the origin URL (thus inheriting the force prefix).
1499 The bug is not considered a security issue and the fix does not make
1500 it harder for remote sites to intentionally circumvent blocks if
1501 Privoxy isn't configured to enforce them.
1502 Fixes #1695 reported by Korda.
1503 - Normalize the request line in intercepted requests to make rewriting
1504 the destination more convenient. Previously rewrites for intercepted
1505 requests were expected to fail unless $hostport was being used, but
1506 they failed "the wrong way" and would result in an out-of-memory
1507 message (vanilla host patterns) or a crash (extended host patterns).
1508 Reported by "Guybrush Threepwood" in #1694.
1509 - Enable socket lingering for the correct socket.
1510 Previously it was repeatedly enabled for the listen socket
1511 instead of for the accepted socket. The bug was found by
1512 code inspection and did not cause any (reported) issues.
1513 - Detect and reject parameters for parameter-less actions.
1514 Previously they were silently ignored.
1515 - Fixed invalid reads in internal and outdated pcre code.
1516 Found with afl-fuzz and AddressSanitizer.
1517 - Prevent invalid read when loading invalid action files.
1518 Found with afl-fuzz and AddressSanitizer.
1519 - Windows build: Use the correct function to close the event handle.
1520 It's unclear if this bug had a negative impact on Privoxy's behaviour.
1521 Reported by Jarry Xu in #891.
1522 - In case of invalid forward-socks5(t) directives, use the
1523 correct directive name in the error messages. Previously they
1524 referred to forward-socks4t failures.
1525 Reported by Joel Verhagen in #889.
1527 - General improvements:
1528 - Set NO_DELAY flag for the accepting socket. This significantly reduces
1529 the latency if the operating system is not configured to set the flag
1530 by default. Reported by Johan Sintorn in #894.
1531 - Allow to build with mingw x86_64. Submitted by Rustam Abdullaev in #135.
1532 - Introduce the new forwarding type 'forward-webserver'.
1533 Currently it is only supported by the forward-override{} action and
1534 there's no config directive with the same name. The forwarding type
1535 is similar to 'forward', but the request line only contains the path
1536 instead of the complete URL.
1537 - The CGI editor no longer treats 'standard.action' special.
1538 Nowadays the official "standards" are part of default.action
1539 and there's no obvious reason to disallow editing them through
1540 the cgi editor anyway (if the user decided that the lack of
1541 authentication isn't an issue in her environment).
1542 - Improved error messages when rejecting intercepted requests
1543 with unknown destination.
1544 - A couple of log messages now include the number of active threads.
1545 - Removed non-standard Proxy-Agent headers in HTTP snipplets
1546 to make testing more convenient.
1547 - Include the error code for pcre errors Privoxy does not recognize.
1548 - Config directives with numerical arguments are checked more carefully.
1549 - Privoxy's malloc() wrapper has been changed to prevent zero-size
1550 allocations which should only occur as the result of bugs.
1551 - Various cosmetic changes.
1553 - Action file improvements:
1554 - Unblock ".deutschlandradiokultur.de/".
1555 Reported by u302320 in #924.
1556 - Add two fast-redirect exceptions for "yandex.ru".
1557 - Disable filter{banners-by-size} for ".plasmaservice.de/".
1558 - Unblock "klikki.fi/adv/".
1559 - Block requests for "resources.infolinks.com/".
1560 Reported by "Black Rider" on ijbswa-users@.
1561 - Block a bunch of criteo domains.
1562 Reported by Black Rider.
1563 - Block "abs.proxistore.com/abe/".
1564 Reported by Black Rider.
1565 - Disable filter{banners-by-size} for ".black-mosquito.org/".
1566 - Disable fast-redirects for "disqus.com/".
1568 - Documentation improvements:
1569 - FAQ: Explicitly point fingers at ASUS as an example of a
1570 company that has been reported to force malware based on
1571 Privoxy upon its customers.
1572 - Correctly document the action type for a bunch of "multi-value"
1573 actions that were incorrectly documented to be "parameterized".
1574 Reported by Gregory Seidman on ijbswa-users@.
1575 - Fixed the documented type of the forward-override{} action
1576 which is obviously 'parameterized'.
1578 - Website improvements:
1579 - Users who don't trust binaries served by SourceForge
1580 can get them from a mirror. Migrating away from SourceForge
1581 is planned for 2016 (TODO list item #53).
1582 - The website is now available as onion service
1583 (http://jvauzb4sb3bwlsnc.onion/).
1585 *** Version 3.0.23 stable ***
1588 - Fixed a DoS issue in case of client requests with incorrect
1589 chunk-encoded body. When compiled with assertions enabled
1590 (the default) they could previously cause Privoxy to abort().
1591 Reported by Matthew Daley. CVE-2015-1380.
1592 - Fixed multiple segmentation faults and memory leaks in the
1593 pcrs code. This fix also increases the chances that an invalid
1594 pcrs command is rejected as such. Previously some invalid commands
1595 would be loaded without error. Note that Privoxy's pcrs sources
1596 (action and filter files) are considered trustworthy input and
1597 should not be writable by untrusted third-parties. CVE-2015-1381.
1598 - Fixed an 'invalid read' bug which could at least theoretically
1599 cause Privoxy to crash. So far, no crashes have been observed.
1601 - Compiles with --disable-force again. Reported by Kai Raven.
1602 - Client requests with body that can't be delivered no longer
1603 cause pipelined requests behind them to be rejected as invalid.
1604 Reported by Basil Hussain.
1606 - General improvements:
1607 - If a pcrs command is rejected as invalid, Privoxy now logs
1608 the cause of the problem as text. Previously the pcrs error
1610 - The tests are less likely to cause false positives.
1612 - Action file improvements:
1613 - '.sify.com/' is no longer blocked. Apparently it is not actually
1614 a pure tracking site (anymore?). Reported by Andrew on ijbswa-users@.
1615 - Unblock banners on .amnesty.de/ which aren't ads.
1617 - Documentation improvements:
1618 - The 'Would you like to donate?' section now also contains
1620 - The list of supported operating systems has been updated.
1621 - The existence of the SF support and feature trackers has been
1622 deemphasized because they have been broken for months.
1623 Most of the time the mailing lists still work.
1624 - The claim that default.action updates are sometimes released
1625 on their own has been removed. It hasn't happened in years.
1626 - Explicitly mention that Tor's port may deviate from the default
1627 when using a bundle. Requested by Andrew on ijbswa-users@.
1629 *** Version 3.0.22 stable ***
1632 - Fixed a memory leak when rejecting client connections due to
1633 the socket limit being reached (CID 66382). This affected
1634 Privoxy 3.0.21 when compiled with IPv6 support (on most
1635 platforms this is the default). CVE-2015-1030.
1636 - Fixed an immediate-use-after-free bug (CID 66394) and two
1637 additional unconfirmed use-after-free complaints made by
1638 Coverity scan (CID 66391, CID 66376). CVE-2015-1031.
1639 - Actually show the FORCE_PREFIX value on the show-status page.
1640 - Properly deal with Keep-Alive headers with timeout= parameters
1641 If the timeout still can't be parsed, use the configured
1642 timeout instead of preventing the client from keeping the
1643 connection alive. Fixes #3615312/#870 reported by Bernard Guillot.
1644 - Not using any filter files no longer results in warning messages
1645 unless an action file is referencing header taggers or filters.
1646 Reported by Stefan Kurtz in #3614835.
1647 - Fixed a bug that prevented Privoxy from reusing some reusable
1648 connections. Two bit masks with different purpose unintentionally
1649 shared the same bit.
1650 - A couple of additional bugs were discovered by Coverity Scan.
1651 The fixes that are not expected to affect users are not explicitly
1652 mentioned here, for details please have a look at the CVS logs.
1654 - General improvements:
1655 - Introduced negative tag patterns NO-REQUEST-TAG and NO-RESPONSE-TAG.
1656 They apply if no matching tag is found after parsing client or
1658 - Add support for external filters which allow to process the
1659 response body with a script or program written in any language
1660 the platform supports. External filters are enabled with
1661 +external-filter{} after they have been defined in one of the
1662 filter files with a header line starting with "EXTERNAL-FILTER:".
1663 External filter support is experimental, not compiled by default
1664 and known not to work on all platforms.
1665 - Add support for the 'PATCH' method as defined in RFC5789.
1666 - Reject requests with unsupported Expect header values.
1667 Fixes a couple of Co-Advisor tests.
1668 - Normalize the HTTP-version in forwarded requests and responses.
1669 This is an explicit RFC 2616 MUST and RFC 7230 mandates that
1670 intermediaries send their own HTTP-version in forwarded
1672 - Server 'Keep-Alive' headers are no longer forwarded. From a user's
1673 point of view it doesn't really matter, but RFC 2616 (obsolete)
1674 mandates that the header is removed and this fixes a Co-Advisor
1676 - Change declared template file encoding to UTF-8. The templates
1677 already used a subset of UTF-8 anyway and changing the declaration
1678 allows to properly display UTF-8 characters used in the action files.
1679 This change may require existing action files with ISO-8859-1
1680 characters that aren't valid UTF-8 to be converted to UTF-8.
1681 Requested by Sam Chen in #582.
1682 - Do not pass rejected keep-alive timeouts to the server. It might
1683 not have caused any problems (we know of), but doing the right
1684 thing shouldn't hurt either.
1685 - Let log_error() use its own buffer size #define to make changing
1686 the log buffer size slightly less inconvenient.
1687 - Turned single-threaded into a "proper" toggle directive with arguments.
1688 - CGI templates no longer enforce new windows for some links.
1689 - Remove an undocumented workaround ('HOST' header removal) for
1690 an Apple iTunes bug that according to #729900 got fixed in 2003.
1692 - Action file improvements:
1693 - The pattern 'promotions.' is no longer being blocked.
1694 Reported by rakista in #3608540.
1695 - Disable fast-redirects for .microsofttranslator.com/.
1696 - Disable filter{banners-by-size} for .dgb-tagungszentren.de/.
1697 - Add adn.speedtest.net as a site-specific unblocker.
1698 Support request #3612908.
1699 - Disable filter{banners-by-size} for creativecommons.org/.
1700 - Block requests to data.gosquared.com/. Reported by cbug in #3613653.
1701 - Unblock .conrad./newsletter/. Reported by David Bo in #3614238.
1702 - Unblock .bundestag.de/.
1703 - Unblock .rote-hilfe.de/.
1704 - Disable fast-redirects for .facebook.com/plugins/like.php.
1705 - Unblock Stackexchange popup URLs that aren't used to serve ads.
1706 Reported by David Wagner in #3615179.
1707 - Disable fast-redirects for creativecommons.org/.
1708 - Unblock .stopwatchingus.info/.
1709 - Block requests for .adcash.com/script/.
1710 Reported by Tyrexionibus in #3615289.
1711 - Disable HTML filters if the response was tagged as JavaScript.
1712 Filtering JavaScript code with filters intended to deal with HTML
1713 is usually a waste of time and, more importantly, may break stuff.
1714 - Use a custom redirect{} for .washingtonpost.com/wp-apps/imrs\.php\?src=
1715 Previously enabling the 'Advanced' settings (or manually enabling
1716 +fast-redirects{}) prevented some images from being loaded properly.
1717 - Unblock "adina*." Fixes #919 reported by Morton A. Goldberg.
1718 - Block '/.*DigiAd'.
1719 - Unblock 'adele*.'. Reported by Adele Lime in #1663.
1720 - Disable banners-by-size for kggp.de/.
1722 - Filter file improvements & bug fixes:
1723 - Decrease the chances that js-annoyances creates invalid JavaScript.
1724 Submitted by John McGowan on ijbswa-users@.
1725 - Let the msn filter hide 'related' ads again.
1726 - Remove a stray '1' in the 'html-annoyances' filter.
1727 - Prevent img-reorder from messing up img tags with empty src
1728 attributes. Fixes #880 reported by Duncan.
1730 - Documentation improvements:
1731 - Updated the 'Would you like to donate?' section.
1732 - Note that invalid forward-override{} parameter syntax isn't
1733 detected until the parameter is used.
1734 - Add another +redirect{} example: a shortcut for illumos bugs.
1735 - Make it more obvious that many operating systems support log
1736 rotation out of the box.
1737 - Fixed dead links. Reported by Mark Nelson in #3614557.
1738 - Rephrased the 'Why is the configuration so complicated?' answer
1739 to be slightly less condescending. Anonymously suggested in #3615122.
1740 - Be more explicit about accept-intercepted-requests's lack of MITM support.
1741 - Make 'demoronizer' FAQ entries more generic.
1742 - Add an example hostname to the --pre-chroot-nslookup description.
1743 - Add an example for a host pattern that matches an IP address.
1744 - Rename the 'domain pattern' to 'host pattern' as it may
1745 contain IP addresses as well.
1746 - Recommend forward-socks5t when using Tor. It seems to work fine and
1747 modifying the Tor configuration to profit from it hasn't been necessary
1749 - Add another redirect{} example to stress that redirect loops can
1750 and should be avoided.
1751 - The usual spelling and grammar fixes. Parts of them were
1752 reported by Reuben Thomas in #3615276.
1753 - Mention the PCRS option letters T and D in the filter section.
1754 - Clarify that handle-as-empty-doc-returns-ok is still useful
1755 and will not be removed without replacement.
1756 - Note that security issues shouldn't be reported using the bug tracker.
1757 - Clarify what Privoxy does if both +block{} and +redirect{} apply.
1758 - Removed the obsolete bookmarklets section.
1760 - Build system improvements:
1761 - Let --with-group properly deal with secondary groups.
1762 Patch submitted by Anatoly Arzhnikov in #3615187.
1763 - Fix web-actions target.
1764 - Add a web-faq target that only updates the FAQ on the webserver.
1765 - Remove already-commented-out non-portable DOSFILTER alternatives.
1766 - Remove the obsolete targets dok-put and dok-get.
1767 - Add a sf-shell target.
1769 *** Version 3.0.21 stable ***
1772 - On POSIX-like platforms, network sockets with file descriptor
1773 values above FD_SETSIZE are properly rejected. Previously they
1774 could cause memory corruption in configurations that allowed
1775 the limit to be reached.
1776 - Proxy authentication headers are removed unless the new directive
1777 enable-proxy-authentication-forwarding is used. Forwarding the
1778 headers potentially allows malicious sites to trick the user
1779 into providing them with login information.
1780 Reported by Chris John Riley.
1781 - Compiles on OS/2 again now that unistd.h is only included
1782 on platforms that have it.
1784 - General improvements:
1785 - The show-status page shows the FEATURE_STRPTIME_SANITY_CHECKS status.
1786 - A couple of assert()s that could theoretically dereference
1787 NULL pointers in debug builds have been relocated.
1788 - Added an LSB info block to the generic start script.
1789 Based on a patch from Natxo Asenjo.
1790 - The max-client-connections default has been changed to 128
1791 which should be more than enough for most setups.
1793 - Action file improvements:
1794 - Block rover.ebay./ar.*\&adtype= instead of "/.*\&adtype=" which
1795 caused too man false positives.
1796 Reported by u302320 in #360284, additional feedback from Adam Piggott.
1797 - Unblock '.advrider.com/' and '/.*ADVrider'.
1798 Anonymously reported in #3603636.
1799 - Stop blocking '/js/slider\.js'.
1800 Reported by Adam Piggott in #3606635 and _lvm in #2791160.
1802 - Filter file improvements:
1803 - Added an iframes filter.
1805 - Documentation improvements:
1806 - The whole GPLv2 text is included in the user manual now,
1807 so Privoxy can serve it itself and the user can read it
1808 without having to wade through GPLv3 ads first.
1809 - Properly numbered and underlined a couple of section titles
1810 in the config that where previously overlooked due to a flaw
1811 in the conversion script. Reported by Ralf Jungblut.
1812 - Improved the support instruction to hopefully make it harder to
1813 unintentionally provide insufficient information when requesting
1814 support. Previously it wasn't obvious that the information we need
1815 in bug reports is usually also required in support requests.
1816 - Removed documentation about packages that haven't been provided
1819 - Privoxy-Regression-Test:
1820 - Only log the test number when not running in verbose mode
1821 The position of the test is rarely relevant and it previously
1822 wasn't exactly obvious which one of the numbers was useful to
1823 repeat the test with --test-number.
1825 - GNUmakefile improvements:
1826 - Factor generate-config-file out of config-file to make testing
1828 - The clean target now also takes care of patch leftovers.
1830 *** Version 3.0.20 beta ***
1833 - Client sockets are now properly shutdown and drained before being
1834 closed. This fixes page truncation issues with clients that aggressively
1835 pipeline data on platforms that otherwise discard already written data.
1836 The issue mainly affected Opera users and was initially reported
1837 by Kevin in #3464439, szotsaki provided additional information to track
1839 - Fix latency calculation for shared connections (disabled by default).
1840 It was broken since their introduction in 2009. The calculated latency
1841 for most connections would be 0 in which case the timeout detection
1842 failed to account for the real latency.
1843 - Reject URLs with invalid port. Previously they were parsed incorrectly and
1844 characters between the port number and the first slash were silently
1845 dropped as shown by curl test 187.
1846 - The default-server-timeout and socket-timeout directives accept 0 as
1848 - Fix a race condition on Windows that could cause Privoxy to become
1849 unresponsive after toggling it on or off through the taskbar icon.
1850 Reported by Tim H. in #3525694.
1851 - Fix the compilation on Windows when configured without IPv6 support.
1852 - Fix an assertion that could cause debug builds to abort() in case of
1853 socks5 connection failures with "debug 2" enabled.
1854 - Fix an assertion that could cause debug builds to abort() if a filter
1855 contained nul bytes in the replacement text.
1857 - General improvements:
1858 - Significantly improved keep-alive support for both client and server
1860 - New debug log level 65536 which logs all actions that were applied to
1862 - New directive client-header-order to forward client headers in a
1863 different order than the one in which they arrived.
1864 - New directive tolerate-pipelining to allow client-side pipelining.
1865 If enabled (3.0.20 beta enables it by default), Privoxy will keep
1866 pipelined client requests around to deal with them once the current
1867 request has been served.
1868 - New --config-test option to let Privoxy exit after checking whether or not
1869 the configuration seems valid. The limitations noted in TODO #22 and #23
1870 still apply. Based on a patch by Ramkumar Chinchani.
1871 - New limit-cookie-lifetime{} action to let cookies expire before the end
1872 of the session. Suggested by Rick Sykes in #1049575.
1873 - Increase the hard-coded maximum number of actions and filter files from
1874 10 to 30 (each). It doesn't significantly affect Privoxy's memory usage
1875 and recompiling wasn't an option for all Privoxy users that reached the
1877 - Add support for chunk-encoded client request bodies. Previously
1878 chunk-encoded request bodies weren't guaranteed to be forwarded correctly,
1879 so this can also be considered a bug fix although chunk-encoded request
1880 bodies aren't commonly used in the real world.
1881 - Add support for Tor's optimistic-data SOCKS extension, which can reduce the
1882 latency for requests on newly created connections. Currently only the
1883 headers are sent optimistically and only if the client request has already
1884 been read completely which rules out requests with large bodies.
1885 - After preventing the client from pipelining, don't signal keep-alive
1886 intentions. When looking at the response headers alone, it previously
1887 wasn't obvious from the client's perspective that no additional responses
1889 - Stop considering client sockets tainted after receiving a request with body.
1890 It hasn't been necessary for a while now and unnecessarily causes test
1891 failures when using curl's test suite.
1892 - Allow HTTP/1.0 clients to signal interest in keep-alive through the
1893 Proxy-Connection header. While such client are rare in the real world, it
1894 doesn't hurt and couple of curl tests rely on it.
1895 - Only remove duplicated Content-Type headers when filters are enabled.
1896 If they are not it doesn't cause ill effects and the user might not want it.
1897 Downgrade the removal message to LOG_LEVEL_HEADER to clarify that it's not
1898 an error in Privoxy and is unlikely to cause any problems in general.
1899 Anonymously reported in #3599335.
1900 - Set the socket option SO_LINGER for the client socket.
1901 - Move several variable declarations to the beginning of their code block.
1902 It's required when compiling with gcc 2.95 which is still used on some
1903 platforms. Initial patch submitted by Simon South in #3564815.
1904 - Optionally try to sanity-check strptime() results before trusting them.
1905 Broken strptime() implementations have caused problems in the past and
1906 the most recent offender seems to be FreeBSD's libc (standards/173421).
1907 - When filtering is enabled, let Range headers pass if the range starts at
1908 the beginning. This should work around (or at least reduce) the video
1909 playback issues with various Apple clients as reported by Duc in #3426305.
1910 - Do not confuse a client hanging up with a connection time out. If a client
1911 closes its side of the connection without sending a request line, do not
1912 send the CLIENT_CONNECTION_TIMEOUT_RESPONSE, but report the condition
1914 - Allow closing curly braces as part of action values as long as they are
1916 - On Windows, the logfile is now written before showing the GUI error
1917 message which blocks until the user acknowledges it.
1918 Reported by Adriaan in #3593603.
1919 - Remove an unreasonable parameter limit in the CGI interface. The new
1920 parameter limit depends on the memory available and is currently unlikely
1921 to be reachable, due to other limits in both Privoxy and common clients.
1922 Reported by Andrew on ijbswa-users@.
1923 - Decrease the chances of parse failures after requests with unsupported
1924 methods were sent to the CGI interface.
1926 - Action file improvements:
1927 - Remove the comment that indicated that updated default.action versions
1928 are released on their own.
1929 - Block 'optimize.indieclick.com/' and 'optimized-by.rubiconproject.com/'
1930 - Unblock 'adjamblog.wordpress.com/' and 'adjamblog.files.wordpress.com/'.
1931 Reported by Ryan Farmer in #3496116.
1932 - Unblock '/.*Bugtracker'. Reported by pwhk in #3522341.
1933 - Add test URLs for '.freebsd.org' and '.watson.org'.
1934 - Unblock '.urbandictionary.com/popular'.
1935 - Block '.adnxs.com/'.

1973 - Filter file improvements & bug fixes:
1974 - Add a referer tagger.
1975 - Reduce the likelihood that the google filter messes up HTML-generating
1976 JavaScript. Reported by Zeno Kugy in #3520260.
1978 - Documentation improvements:
1979 - Revised all OS X sections due to new packaging module (OSXPackageBuilder).
1980 - Update the list of supported operating systems to clarify that all Windows
1981 versions after 95 are expected to work and note that the platform-specific
1982 code for AmigaOS and QNX currently isn't maintained.
1983 - Update 'Signals' section, the only explicitly handled signals are SIGINT,
1985 - Add Haiku to the list of operating systems on which Privoxy is known to
1987 - Add DragonFly to the list of BSDs on which Privoxy is known to run.
1988 - Removed references to redhat-specific documentation set since it no longer
1990 - Removed references to building PDFs since we no longer do so.
1991 - Multiple listen-address directives are supported since 3.0.18, correct the
1992 documentation to say so.
1993 - Remove bogus section about long and short being preferable to int.
1994 - Corrected some Internet JunkBuster references to Privoxy.
1995 - Removed references to www.junkbusters.com since it is no longer
1996 maintained. Reported by Angelina Matson.
1997 - Various grammar and spelling corrections
1998 - Add a client-header-tagger{} example for disabling filtering for range
2000 - Correct a URL in the "Privoxy with Tor" FAQ.
2001 - Spell 'refresh-tags' correctly. Reported by Don in #3571927.
2002 - Sort manpage options alphabetically.
2003 - Remove an incorrect sentence in the toggle section. The toggle state
2004 doesn't affect whether or not the Windows version uses the tray icon.
2005 Reported by Zeno Kugy in #3596395.
2006 - Add new contributors since 3.0.19.
2008 - Log message improvements:
2009 - When stopping to watch a client socket due to pipelining, additionally log
2011 - Log the client socket and its condition before closing it. This makes it
2012 more obvious that the socket actually gets closed and should help when
2013 diagnosing problems like #3464439.
2014 - In case of SOCKS5 failures, do not explicitly log the server's response.
2015 It hasn't helped so far and the response can already be logged by enabling
2016 "debug 32768" anyway. This reverts v1.81 and the follow-up bug fix v1.84.
2017 - Relocate the connection-accepted message from listen_loop() to serve().
2018 This way it's printed by the thread that is actually serving the
2019 connection which is nice when grepping for thread ids in log files.
2022 - Remove compatibility layer for versions prior to 3.0 since it has been
2023 obsolete for more than 10 years now.
2024 - Remove the ijb_isupper() and ijb_tolower() macros from parsers.c since
2025 they aren't used in this file.
2026 - Removed the 'Functions declared include:' comment sections since they tend
2027 to be incomplete, incorrect and out of date and the benefit seems
2029 - Various comment grammar and comprehensibility improvements.
2030 - Remove a pointless fflush() call in chat(). Flushing all streams pretty
2031 much all the time for no obvious reason is ridiculous.
2032 - Relocate ijb_isupper()'s definition to project.h and get the ijb_tolower()
2033 definition from there, too.
2034 - Relocate ijb_isdigit()'s definition to project.h.
2035 - Rename ijb_foo macros to privoxy_foo.
2036 - Add malloc_or_die() which will allow to simplify code paths where malloc()
2037 failures don't need to be handled gracefully.
2038 - Add strdup_or_die() which will allow to simplify code paths where strdup()
2039 failures don't need to be handled gracefully.
2040 - Replace strdup() calls with strdup_or_die() calls where it's safe and
2041 simplifies the code.
2042 - Fix white-space around parentheses.
2043 - Add missing white-space behind if's and the following parentheses.
2044 - Unwrap a memcpy() call in resolve_hostname_to_ip().
2045 - Declare pcrs_get_delimiter()'s delimiters[] static const.
2046 - Various optimisations to remove dead code and merge inefficient code
2047 structures for improved clarity, performance or code compactness.
2048 - Various data type corrections.
2049 - Change visibility of several code segments when compiling without
2050 FEATURE_CONNECTION_KEEP_ALIVE enabled for clarity.
2051 - In pcrs_get_delimiter(), do not use delimiters outside the ASCII range.
2052 Fixes a clang complaint.
2053 - Fix an error message in get_last_url() nobody is supposed to see.
2054 Reported by Matthew Fischer in #3507301.
2055 - Fix a typo in the no-zlib-support complaint. Patch submitted by Matthew
2056 Fischer in #3507304.
2057 - Shorten ssplit()'s prototype by removing the last two arguments. We always
2058 want to skip empty fields and ignore leading delimiters, so having
2059 parameters for this only complicates the API.
2060 - Use an enum for the type of the action value.
2061 - Rename action_name's member takes_value to value_type as it isn't used as
2063 - Turn family mismatches in match_sockaddr() into fatal errors.
2064 - Let enlist_unique_header() verify that the caller didn't pass a header
2065 containing either \r or \n.
2066 - Change the hashes used in load_config() to unsigned int. That's what
2067 hash_string() actually returns and using a potentially larger type
2069 - Use privoxy_tolower() instead of vanilla tolower() with manual casting of
2071 - Catch ssplit() failures in parse_cgi_parameters().
2073 - Privoxy-Regression-Test:
2074 - Add an 'Overwrite condition' directive to skip any matching tests before
2075 it. As it has a global scope, using it is more convenient than clowning
2076 around with the Ignore directive.
2077 - Log to STDOUT instead of STDERR.
2078 - Include the Privoxy version in the output.
2079 - Various grammar and spelling corrections in documentation and code.
2080 - Additional tests for range requests with filtering enabled.
2081 - Tests with mostly invalid range request.
2082 - Add a couple of hide-if-modified-since{} tests with different date formats.
2083 - Cleaned up the format of the regression-tests.action file to match the
2084 format of default.action.
2085 - Remove the "Copyright" line from print_version(). When using --help, every
2086 line of screen space matters and thus shouldn't be wasted on things the
2087 user doesn't care about.
2089 - Privoxy-Log-Parser:
2090 - Improve the --statistics performance by skipping sanity checks for input
2091 that shouldn't affect the results anyway. Add a --strict-checks option
2092 that enables some of the checks again, just in case anybody cares.
2093 - The distribution of client requests per connection is included in
2094 the --statistic output.
2095 - The --accept-unknown-messages option has been removed and the behavior
2097 - Accept and (mostly) highlight new log messages introduced with
2101 - Bump generated Firefox version to 17.
2103 - GNUmakefile improvements:
2104 - The dok-tidy target no longer taints documents with a tidy-mark
2105 - Change RA_MODE from 0664 to 0644. Suggested by Markus Dittrich in
2107 - Remove tidy's clean flag as it changes the scope of attributes.
2108 Link-specific colors end up being applied to all text. Reported by Adam
2109 Piggott in #3569551.
2110 - Leave it up to the user whether or not smart tags are inserted.
2111 - Let w3m itself do the line wrapping for the config file. It works better
2112 than fmt as it can honour pre tags causing less unintentional line breaks.
2113 - Ditch a pointless '-r' passed to rm to delete files.
2114 - The config-file target now requires less manual intervention and updates
2115 the original config.
2116 - Change WDUMP to generate ASCII. Add WDUMP_UTF8 to allow UTF-8 in the
2117 AUTHORS file so the names are right.
2118 - Stop pretending that lynx and links are supported for the documentation.
2120 - configure improvements:
2121 - On Haiku, do not pass -lpthread to the compiler. Haiku's pthreads
2122 implementation is contained in its system library, libroot, so no
2123 additional library needs to be searched.
2124 Patch submitted by Simon South in #3564815.
2125 - Additional Haiku-specific improvements. Disable checks intended for
2126 multi-user systems as Haiku is presently single-user. Group Haiku-specific
2127 settings in their own section, following the pattern for Solaris, OS/2 and
2128 AmigaOS. Add additional library-related settings to remove the need for
2129 providing configure with custom LDFLAGS.
2130 Submitted by Simon South in #3574538.
2132 *** Version 3.0.19 Stable ***
2135 - Prevent a segmentation fault when de-chunking buffered content.
2136 It could be triggered by malicious web servers if Privoxy was
2137 configured to filter the content and running on a platform
2138 where SIZE_T_MAX isn't larger than UINT_MAX, which probably
2139 includes most 32-bit systems. On those platforms, all Privoxy
2140 versions before 3.0.19 appear to be affected.
2141 To be on the safe side, this bug should be presumed to allow
2142 code execution as proving that it doesn't seems unrealistic.
2143 - Do not expect a response from the SOCKS4/4A server until it
2144 got something to respond to. This regression was introduced
2145 in 3.0.18 and prevented the SOCKS4/4A negotiation from working.
2146 Reported by qqqqqw in #3459781.
2148 - General improvements:
2149 - Fix an off-by-one in an error message about connect failures.
2150 - Use a GNUMakefile variable for the webserver root directory and
2151 update the path. Sourceforge changed it which broke various
2152 web-related targets.
2153 - Update the CODE_STATUS description.
2155 *** Version 3.0.18 Stable ***
2158 - If a generated redirect URL contains characters RFC 3986 doesn't
2159 permit, they are (re)encoded. Not doing this makes Privoxy versions
2160 from 3.0.5 to 3.0.17 susceptible to HTTP response splitting (CWE-113)
2161 attacks if the +fast-redirects{check-decoded-url} action is used.
2162 - Fix a logic bug that could cause Privoxy to reuse a server
2163 socket after it got tainted by a server-header-tagger-induced
2164 block that was triggered before the whole server response had
2165 been read. If keep-alive was enabled and the request following
2166 the blocked one was to the same host and using the same forwarding
2167 settings, Privoxy would send it on the tainted server socket.
2168 While the server would simply treat it as a pipelined request,
2169 Privoxy would later on fail to properly parse the server's
2170 response as it would try to parse the unread data from the
2171 first response as server headers for the second one.
2172 Regression introduced in 3.0.17.
2173 - When implying keep-alive in client_connection(), remember that
2174 the client didn't. Fixes a regression introduced in 3.0.13 that
2175 would cause Privoxy to wait for additional client requests after
2176 receiving a HTTP/1.1 request with "Connection: close" set
2177 and connection sharing enabled.
2178 With clients which terminates the client connection after detecting
2179 that the whole body has been received it doesn't really matter,
2180 but with clients that don't the connection would be kept open until
2182 - Fix a subtle race condition between prepare_csp_for_next_request()
2183 and sweep(). A thread preparing itself for the next client request
2184 could briefly appear to be inactive.
2185 If all other threads were already using more recent files,
2186 the thread could get its files swept away under its feet.
2187 So far this has only been reproduced while stress testing in
2188 valgrind while touching action files in a loop. It's unlikely
2189 to have caused any actual problems in the real world.
2190 - Disable filters if SDCH compression is used unless filtering is forced.
2191 If SDCH was combined with a supported compression algorithm, Privoxy
2192 previously could try to decompress it and ditch the Content-Encoding
2193 header even though the SDCH compression wasn't dealt with.
2194 Reported by zebul666 in #3225863.
2195 - Make a copy of the --user value and only mess with that when splitting
2196 user and group. On some operating systems modifying the value directly
2197 is reflected in the output of ps and friends and can be misleading.
2198 Reported by zepard in #3292710.
2199 - If forwarded-connect-retries is set, only retry if Privoxy is actually
2200 forwarding the request. Previously direct connections would be retried
2202 - Fixed a small memory leak when retrying connections with IPv6
2204 - Remove an incorrect assertion in compile_dynamic_pcrs_job_list()
2205 It could be triggered by a pcrs job with an invalid pcre
2206 pattern (for example one that contains a lone quantifier).
2207 - If the --user argument user[.group] contains a dot, always bail out
2208 if no group has been specified. Previously the intended, but undocumented
2209 (and apparently untested), behaviour was to try interpreting the whole
2210 argument as user name, but the detection was flawed and checked for '0'
2211 instead of '\0', thus merely preventing group names beginning with a zero.
2212 - In html_code_map[], use a numeric character reference instead of '
2213 which wasn't standardized before XHTML 1.0.
2214 - Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION
2215 and shut down through http://config.privoxy.org/die
2216 - In get_actions(), fix the "temporary" backwards compatibility hack
2217 to accept block actions without reason.
2218 It also covered other actions that should be rejected as invalid.
2219 Reported by Billy Crook.
2221 - General improvements:
2222 - Privoxy can (re)compress buffered content before delivering
2223 it to the client. Disabled by default as most users wouldn't
2225 - The +fast-redirects{check-decoded-url} action checks URL
2226 segments separately. If there are other parameters behind
2227 the redirect URL, this makes it unnecessary to cut them off
2228 by additionally using a +redirect{} pcrs command.
2229 Initial patch submitted by Jamie Zawinski in #3429848.
2230 - When loading action sections, verify that the referenced filters
2231 exist. Currently missing filters only result in an error message,
2232 but eventually the severity will be upgraded to fatal.
2233 - Allow to bind to multiple separate addresses.
2234 Patch set submitted by Petr Pisar in #3354485.
2235 - Set socket_error to errno if connecting fails in rfc2553_connect_to().
2236 Previously rejected direct connections could be incorrectly reported
2237 as DNS issues if Privoxy was compiled with IPv6 support.
2238 - Adjust url_code_map[] so spaces are replaced with %20 instead of '+'
2239 While '+' can be used by client's submitting form data, this is not
2240 actually what Privoxy is using the lookups for. This is more of a
2241 cosmetic issue and doesn't fix any known problems.
2242 - When compiled without FEATURE_FAST_REDIRECTS, do not silently
2243 ignore +fast-redirect{} directives
2244 - Added a workaround for GNU libc's strptime() reporting negative
2245 year values when the parsed year is only specified with two digits.
2246 On affected systems cookies with such a date would not be turned
2247 into session cookies by the +session-cookies-only action.
2248 Reported by Vaeinoe in #3403560
2249 - Fixed bind failures with certain GNU libc versions if no non-loopback
2250 IP address has been configured on the system. This is mainly an issue
2251 if the system is using DHCP and Privoxy is started before the network
2252 is completely configured.
2253 Reported by Raphael Marichez in #3349356.
2254 Additional insight from Petr Pisar.
2255 - Privoxy log messages now use the ISO 8601 date format %Y-%m-%d.
2256 It's only slightly longer than the old format, but contains
2257 the full date including the year and allows sorting by date
2258 (when grepping in multiple log files) without hassle.
2259 - In get_last_url(), do not bother trying to decode URLs that do
2260 not contain at least one '%' sign. It reduces the log noise and
2261 a number of unnecessary memory allocations.
2262 - In case of SOCKS5 failures, dump the socks response in the log message.
2263 - Simplify the signal setup in main().
2264 - Streamline socks5_connect() slightly.
2265 - In socks5_connect(), require a complete socks response from the server.
2266 Previously Privoxy didn't care how much data the server response
2267 contained as long as the first two bytes contained the expected
2268 values. While at it, shrink the buffer size so Privoxy can't read
2269 more than a whole socks response.
2270 - In chat(), do not bother to generate a client request in case of
2271 direct CONNECT requests. It will not be used anyway.
2272 - Reduce server_last_modified()'s stack size.
2273 - Shorten get_http_time() by using strftime().
2274 - Constify the known_http_methods pointers in unknown_method().
2275 - Constify the time_formats pointers in parse_header_time().
2276 - Constify the formerly_valid_actions pointers in action_used_to_be_valid().
2277 - Introduce a GNUMakefile MAN_PAGE variable that defaults to privoxy.1.
2278 The Debian package uses section 8 for the man page and this
2279 should simplify the patch.
2280 - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
2281 - In block_url(), ditch the obsolete workaround for ancient Netscape versions
2282 that supposedly couldn't properly deal with status code 403.
2283 - Remove a useless NULL pointer check in load_trustfile().
2284 - Remove two useless NULL pointer checks in load_one_re_filterfile().
2285 - Change url_code_map[] from an array of pointers to an array of arrays
2286 It removes an unnecessary layer of indirection and on 64bit system reduces
2287 the size of the binary a bit.
2288 - Fix various typos. Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
2289 - Add a dok-tidy GNUMakefile target to clean up the messy HTML
2290 generated by the other dok targets.
2291 - GNUisms in the GNUMakefile have been removed.
2292 - Change the HTTP version in static responses to 1.1
2293 - Synced config.sub and config.guess with upstream
2294 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
2295 - Add a dedicated function to parse the values of toggles. Reduces duplicated
2296 code in load_config() and provides better error handling. Invalid or missing
2297 toggle values are now a fatal error instead of being silently ignored.
2298 - Terminate HTML lines in static error messages with \n instead of \r\n.
2299 - Simplify cgi_error_unknown() a bit.
2300 - In LogPutString(), don't bother looking at pszText when not
2301 actually logging anything.
2302 - Change ssplit()'s fourth parameter from int to size_t.
2303 Fixes a clang complaint.
2304 - Add a warning that the statistics currently can't be trusted.
2305 Mention Privoxy-Log-Parser's --statistics option as
2306 an alternative for the time being.
2307 - In rfc2553_connect_to(), start setting cgi->error_message on error.
2308 - Change the expected status code returned for http://p.p/die depending
2309 on whether or not FEATURE_GRACEFUL_TERMINATION is available.
2310 - In cgi_die(), mark the client connection for closing.
2311 If the client will fetch the style sheet through another connection
2312 it gets the main thread out of the accept() state and should thus
2313 trigger the actual shutdown.
2314 - Add a proper CGI message for cgi_die().
2315 - Don't enforce a logical line length limit in read_config_line().
2316 - Slightly refactor server_last_modified() to remove useless gmtime*() calls.
2317 - In get_content_type(), also recognize '.jpeg' as JPEG extension.
2318 - Add '.png' to the list of recognized file extensions in get_content_type().
2319 - In block_url(), consistently use the block reason "Request blocked by Privoxy"
2320 In two places the reason was "Request for blocked URL" which hides the
2321 fact that the request got blocked by Privoxy and isn't necessarily
2322 correct as the block may be due to tags.
2323 - In listen_loop(), reload the configuration files after accepting
2324 a new connection instead of before.
2325 Previously the first connection that arrived after a configuration
2326 change would still be handled with the old configuration.
2327 - In chat()'s receive-data loop, skip a client socket check if
2328 the socket will be written to right away anyway. This can
2329 increase the transfer speed for unfiltered content on fast
2330 network connections.
2331 - The socket timeout is used for SOCKS negotiations as well which
2332 previously couldn't timeout.
2333 - Don't keep the client connection alive if any configuration file
2334 changed since the time the connection came in. This is closer to
2335 Privoxy's behaviour before keep-alive support for client connection
2336 has been added and also less confusing in general.
2337 - Treat all Content-Type header values containing the pattern
2338 'script' as a sign of text. Reported by pribog in #3134970.
2340 - Action file improvements:
2341 - Moved the site-specific block pattern section below the one for the
2342 generic patterns so for requests that are matched in both, the block
2343 reason for the domain is shown which is usually more useful than showing
2344 the one for the generic pattern.
2345 - Remove -prevent-compression from the fragile alias. It's no longer
2346 used anywhere by default and isn't known to break stuff anyway.
2347 - Add a (disabled) section to block various Facebook tracking URLs.
2348 Reported by Dan Stahlke in #3421764.
2349 - Add a (disabled) section to rewrite and redirect click-tracking
2350 URLs used on news.google.com.
2351 Reported by Dan Stahlke in #3421755.
2352 - Unblock linuxcounter.net/.
2353 Reported by Dan Stahlke in #3422612.
2354 - Block 'www91.intel.com/' which is used by Omniture.
2355 Reported by Adam Piggott in #3167370.
2356 - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
2357 Reminded by tceverling in #2790091.
2358 - Add ".ivwbox.de/" to the "Cross-site user tracking" section.
2359 Reported by Nettozahler in #3172525.
2360 - Unblock and fast-redirect ".awin1.com/.*=http://".
2361 Reported by Adam Piggott in #3170921.
2362 - Block "b.collective-media.net/".
2363 - Widen the Debian popcon exception to "qa.debian.org/popcon".
2364 Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
2365 - Block ".gemius.pl/" which only seems to be used for user tracking.
2366 Reported by johnd16 in #3002731. Additional input from Lee and movax.
2367 - Disable banners-by-size filters for '.thinkgeek.com/'.
2368 The filter only seems to catch pictures of the inventory.
2369 - Block requests for 'go.idmnet.bbelements.com/please/showit/'.
2370 Reported by kacperdominik in #3372959.
2371 - Unblock adainitiative.org/.
2372 - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'.
2373 - Add a fast-redirects exception for webcache.googleusercontent.com/.
2374 - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/.
2376 - Filter file improvements:
2377 - Let the yahoo filter hide '.ads'.
2378 - Let the msn filter hide overlay ads for Facebook 'likes' in search
2379 results and elements with the id 's_notf_div'. They only seem to be
2380 used to advertise site 'enhancements'.
2381 - Let the js-events filter additionally disarm setInterval().
2382 Suggested by dg1727 in #3423775.
2384 - Documentation improvements:
2385 - Clarify the effect of compiling Privoxy with zlib support.
2386 Suggested by dg1727 in #3423782.
2387 - Point out that the SourceForge messaging system works like a black
2388 hole and should thus not be used to contact individual developers.
2389 - Mention some of the problems one can experience when not explicitly
2390 configuring an IP addresses as listen address.
2391 - Explicitly mention that hostnames can be used instead of IP addresses
2392 for the listen-address, that only the first address returned will be
2393 used and what happens if the address is invalid.
2394 Requested by Calestyo in #3302213.
2396 - Log message improvements:
2397 - If only the server connection is kept alive, do not pretend to
2398 wait for a new client request.
2399 - Remove a superfluous log message in forget_connection().
2400 - In chat(), properly report missing server responses as such
2401 instead of calling them empty.
2402 - In forwarded_connect(), fix a log message nobody should ever see.
2403 - Fix a log message in socks5_connect(), a failed write operation
2404 was logged as failed read operation.
2405 - Let load_one_actions_file() properly complain about a missing
2406 '{' at the beginning of the file.
2407 Simply stating that a line is invalid isn't particularly helpful.
2408 - Do not claim to listen on a socket until Privoxy actually does.
2409 Patch submitted by Petr Pisar #3354485
2410 - Prevent a duplicated LOG_LEVEL_CLF message when sending out
2411 the "no-server-data" response.
2412 - Also log the client socket when dropping a connection.
2413 - Include the destination host in the 'Request ... marked for
2414 blocking. limit-connect{...} doesn't allow CONNECT ...' message
2415 Patch submitted by Saperski in #3296250.
2416 - Prevent a duplicated log message if none of the resolved IP
2417 addresses were reachable.
2418 - In connect_to(), do not pretend to retry if forwarded-connect-retries
2420 - When a specified user or group can't be found, put the name in
2421 single-quotes when logging it.
2422 - In rfc2553_connect_to(), explain getnameinfo() errors better.
2423 - Remove a useless log message in chat().
2424 - When retrying to connect, also log the maximum number of connection
2426 - Rephrase a log message in compile_dynamic_pcrs_job_list().
2427 Divide the error code and its meaning with a colon. Call the pcrs
2428 job dynamic and not the filter. Filters may contain dynamic and
2429 non-dynamic pcrs jobs at the same time. Only mention the name of
2430 the filter or tagger, but don't claim it's a filter when it could
2432 - In a fatal error message in load_one_actions_file(), cover both
2433 URL and TAG patterns.
2434 - In pcrs_strerror(), properly report unknown positive error code
2435 values as such. Previously they were handled like 0 (no error).
2436 - In compile_dynamic_pcrs_job_list(), also log the actual error code as
2437 pcrs_strerror() doesn't handle all errors reported by pcre.
2438 - Don't bother trying to continue chatting if the client didn't ask for it.
2439 Reduces log noise a bit.
2440 - Make two fatal error message in load_one_actions_file() more descriptive.
2441 - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'.
2442 - In load_file(), log a message if opening a file failed.
2443 The CGI error message alone isn't too helpful.
2444 - In connection_destination_matches(), improve two log messages
2445 to help understand why the destinations don't match.
2446 - Rephrase a log message in serve(). Client request arrival
2447 should be differentiated from closed client connections now.
2448 - In serve(), log if a client connection isn't reused due to a
2449 configuration file change.
2450 - Let mark_server_socket_tainted() always mark the server socket tainted,
2451 just don't talk about it in cases where it has no effect. It doesn't change
2452 Privoxy's behaviour, but makes understanding the log file easier.
2455 - Added a --disable-ipv6-support switch for platforms where support
2456 is detected but doesn't actually work.
2457 - Do not check for the existence of strerror() and memmove() twice
2458 - Remove a useless test for setpgrp(2). Privoxy doesn't need it and
2459 it can cause problems when cross-compiling.
2460 - Rename the --disable-acl-files switch to --disable-acl-support.
2461 Since about 2001, ACL directives are specified in the standard
2463 - Update the URL of the 'Removing outdated PCRE version after the
2464 next stable release' posting. The old URL stopped working after
2465 one of SF's recent site "optimizations". Reported by Han Liu.
2467 - Privoxy-Regression-Test:
2468 - Added --shuffle-tests option to increase the chances of detection race conditions.
2469 - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy.
2470 - Added tests for missing socks4 and socks4a forwarders.
2471 - The --privoxy-address option now works with IPv6 addresses containing brackets, too.
2472 - Perform limited sanity checks for parameters that are supposed to have numerical values.
2473 - Added a --sleep-time option to specify a number of seconds to
2474 sleep between tests, defaults to 0.
2475 - Disable the range-requests tagger for tests that break if it's enabled.
2476 - Log messages use the ISO 8601 date format %Y-%m-%d.
2477 - Fix spelling in two error messages.
2478 - In the --help output, include a list of supported tests and their default levels.
2479 - Adjust the tests to properly deal with FEATURE_TOGGLE being disabled.
2481 - Privoxy-Log-Parser:
2482 - Perform limited sanity checks for command line parameters that
2483 are supposed to have numerical values.
2484 - Implement a --unbreak-lines-only option to try to revert MUA breakage.
2485 - Accept and highlight: Added header: Content-Encoding: deflate
2486 - Accept and highlight: Compressed content from 29258 to 8630 bytes.
2487 - Accept and highlight: Client request arrived in time on socket 21.
2488 - Highlight: Didn't receive data in time: a.fsdn.com:443
2489 - Accept log messages with ISO 8601 time stamps, too.
2492 - Bump generated Firefox version to 8.0.
2493 - Only randomize the release date if the new --randomize-release-date
2494 option is enabled. Firefox versions after 4 use a fixed date string
2497 *** Version 3.0.17 Stable ***
2499 - Fixed last-chunk-detection for responses where the body was small
2500 enough to be read with the headers, causing Privoxy to wait for the
2501 end of the content until the server closed the connection or the
2502 request timed out. Reported by "Karsten" in #3028326.
2503 - Responses with status code 204 weren't properly detected as body-less
2504 like RFC2616 mandates. Like the previous bug, this caused Privoxy to
2505 wait for the end of the content until the server closed the connection
2506 or the request timed out. Fixes #3022042 and #3025553, reported by a
2507 user with no visible name. Most likely also fixes a bunch of other
2508 AJAX-related problem reports that got closed in the past due to
2509 insufficient information and lack of feedback.
2510 - Fixed an ACL bug that made it impossible to build a blacklist.
2511 Usually the ACL directives are used in a whitelist, which worked
2512 as expected, but blacklisting is still useful for public proxies
2513 where one only needs to deny known abusers access.
2514 - Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
2515 network. This should make debugging various parsing issues a lot easier.
2516 - The IPv6 code is enabled by default on Windows versions that support it.
2517 Patch submitted by oCameLo in #2942729.
2518 - In mingw32 versions, the user.filter file is reachable through the
2519 GUI, just like default.filter is. Feature request 3040263.
2520 - Added the configure option --enable-large-file-support to set a few
2521 defines that are required by platforms like GNU/Linux to support files
2522 larger then 2GB. Mainly interesting for users without proper logfile
2524 - Logging with "debug 16" no longer stops at the first nul byte which is
2525 pretty useless. Non-printable characters are replaced with their hex value
2526 so the result can't span multiple lines making parsing them harder then
2528 - Privoxy logs when reading an action, filter or trust file.
2529 - Fixed incorrect regression test markup which caused a test in
2530 3.0.16 to fail while Privoxy itself was working correctly.
2531 While Privoxy accepts hide-referer, too, the action name is actually
2532 hide-referrer which is also the name used one the final results page,
2533 where the test expected the alias.
2535 - CGI interface improvements:
2536 - In finish_http_response(), continue to add the 'Connection: close'
2537 header if the client connection will not be kept alive.
2538 Anonymously pointed out in #2987454.
2539 - Apostrophes in block messages no longer cause parse errors
2540 when the blocked page is viewed with JavaScript enabled.
2541 Reported by dg1727 in #3062296.
2542 - Fix a bunch of anchors that used underscores instead of dashes.
2543 - Allow to keep the client connection alive after crunching the previous request.
2544 Already opened server connections can be kept alive, too.
2545 - In cgi_show_url_info(), don't forget to prefix URLs that only contain
2546 http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott.
2547 - Show the 404 CGI page if cgi_send_user_manual() is called while
2548 local user manual delivery is disabled.
2550 - Action file improvements:
2551 - Enable user.filter by default. Suggested by David White in #3001830.
2552 - Block .sitestat.com/. Reported by johnd16 in #3002725.
2553 - Block .atemda.com/. Reported by johnd16 in #3002723.
2554 - Block js.adlink.net/. Reported by johnd16 in #3002720.
2555 - Block .analytics.yahoo.com/. Reported by johnd16 in #3002713.
2556 - Block sb.scorecardresearch.com, too. Reported by dg1727 in #2992652.
2557 - Fix problems noticed on Yahoo mail and news pages.
2558 - Remove the too broad yahoo section, only keeping the
2559 fast-redirects exception as discussed on ijbswa-devel@.
2560 - Don't block adesklets.sourceforge.net. Reported in #2974204.
2561 - Block chartbeat ping tracking. Reported in #2975895.
2562 - Tag CSS and image requests with cautious and medium settings, too.
2563 - Don't handle view.atdmt.com as image. It's used for click-throughs
2564 so users should be able to "go there anyway".
2565 Reported by Adam Piggott in #2975927.
2566 - Also let the refresh-tags filter remove invalid refresh tags where
2567 the 'url=' part is missing. Anonymously reported in #2986382.
2568 While at it, update the description to mention the fact that only
2569 refresh tags with refresh times above 9 seconds are covered.
2570 - javascript needs to be blocked with +handle-as-empty-document to
2571 work around Firefox bug 492459. So move .js blockers from
2572 +block{Might be a web-bug.} -handle-as-empty-document to
2573 +block{Might be a web-bug.} +handle-as-empty-document.
2574 - ijbswa-Feature Requests-3006719 - Block 160x578 Banners.
2575 - Block another omniture tracking domain.
2576 - Added a range-requests tagger.
2577 - Added two sections to get Flickr's Ajax interface working with
2578 default pre-settings. If you change the configuration to block
2579 cookies by default, you'll need additional exceptions.
2580 Reported by Mathias Homann in #3101419 and by Patrick on ijbswa-users@.
2582 - Documentation improvements:
2583 - Explicitly mention how to match all URLs.
2584 - Consistently recommend socks5 in the Tor FAQ entry and mention
2585 its advantage compared to socks4a. Reported by David in #2960129.
2586 - Slightly improve the explanation of why filtering may appear
2588 - Grammar fixes for the ACL section.
2589 - Fixed a link to the 'intercepting' entry and add another one.
2590 - Rename the 'Other' section to 'Mailing Lists' and reword it
2591 to make it clear that nobody is forced to use the trackers
2592 - Note that 'anonymously' posting on the trackers may not always
2594 - Suggest to enable debug 32768 when suspecting parsing problems.
2596 - Privoxy-Log-Parser improvements:
2597 - Gather statistics for ressources, methods, and HTTP versions
2599 - Also gather statistics for blocked and redirected requests.
2600 - Provide the percentage of keep-alive offers the client accepted.
2601 - Add a --url-statistics-threshold option.
2602 - Add a --host-statistics-threshold option to also gather
2603 statistics about how many request where made per host.
2604 - Fix a bug in handle_loglevel_header() where a 'scan: ' got lost.
2605 - Add a --shorten-thread-ids option to replace the thread id with
2607 - Accept and ignore: Looks like we got the last chunk together
2608 with the server headers. We better stop reading.
2609 - Accept and ignore: Continue hack in da house.
2610 - Accept and higlight: Rejecting connection from 10.0.0.2.
2611 Maximum number of connections reached.
2612 - Accept and highlight: Loading actions file: /usr/local/etc/privoxy/default.action
2613 - Accept and highlight: Loading filter file: /usr/local/etc/privoxy/default.filter
2614 - Accept and highlight: Killed all-caps Host header line: HOST: bestproxydb.com
2615 - Accept and highlight: Reducing expected bytes to 0. Marking
2616 the server socket tainted after throwing 4 bytes away.
2617 - Accept: Merged multiple header lines to: 'X-FORWARDED-PROTO: http X-HOST: 127.0.0.1'
2620 - Remove the next member from the client_state struct. Only the main
2621 thread needs access to all client states so give it its own struct.
2622 - Garbage-collect request_contains_null_bytes().
2623 - Ditch redundant code in unload_configfile().
2624 - Ditch LogGetURLUnderCursor() which doesn't seem to be used anywhere.
2625 - In write_socket(), remove the write-only variable write_len in
2626 an ifdef __OS2__ block. Spotted by cppcheck.
2627 - In connect_to(), don't declare the variable 'flags' on OS/2 where
2628 it isn't used. Spotted by cppcheck.
2629 - Limit the scope of various variables. Spotted by cppcheck.
2630 - In add_to_iob(), turn an interestingly looking for loop into a
2632 - Code cleanup in preparation for external filters.
2633 - In listen_loop(), mention the socket on which we accepted the
2634 connection, not just the source IP address.
2635 - In write_socket(), also log the socket we're writing to.
2636 - In log_error(), assert that escaped characters get logged
2637 completely or not at all.
2638 - In log_error(), assert that ival and sval have reasonable values.
2639 There's no reason not to abort() if they don't.
2640 - Remove an incorrect cgi_error_unknown() call in a
2641 cannot-happen-situation in send_crunch_response().
2642 - Clean up white-space in http_response definition and
2643 move the crunch_reason to the beginning.
2644 - Turn http_response.reason into an enum and rename it
2645 to http_response.crunch_reason.
2646 - Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686 GNU/Linux.
2647 - Fix white-space in a log message in remove_chunked_transfer_coding().
2648 While at it, add a note that the message doesn't seem to
2649 be entirely correct and should be improved later on.
2651 - GNUmakefile improvements:
2652 - Use $(SSH) instead of ssh, so one only needs to specify a username once.
2653 - Removed references to the action feedback thingy that hasn't been
2655 - Consistently use shell.sourceforge.net instead of shell.sf.net so
2656 one doesn't need to check server fingerprints twice.
2657 - Removed GNUisms in the webserver and webactions targets so they
2658 work with standard tar.
2660 *** Version 3.0.16 Stable ***
2662 - Added the config file option handle-as-empty-doc-returns-ok to
2663 work around Firefox bug #492459, which causes Firefox to hang
2664 if JavaScripts are blocked in certain situations. The option is
2665 enabled in the default config file.
2666 - Added the config file option default-server-timeout to control the
2667 assumed default server timeout. Since Privoxy no longer returns
2668 an error message for connection resets on reused client connections,
2669 assuming larger server timeout values appears to actually work
2670 pretty well as long as connections aren't shared.
2671 - Added optional support for FreeBSD's accf_http(9). Use the
2672 configure option --enable-accept-filter to enable it.
2673 - Added fancier Privoxy icons for win32. Contributed by Jeff H.
2674 - In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
2675 - Resolve localhost using whatever address family the operating
2676 system feels like. Previous betas would try to use IPv4 as this
2677 is what most users expect, but this didn't work reliably on
2679 - In the action lists on CGI pages, actions and their parameters are
2680 no longer separated with a space. The action file parser doesn't
2681 actually allow this and will throw an invalid syntax error if actions
2682 and parameters in the action files are separated. Not adding the
2683 spaces means copy and pasting CGI output into the action files works.
2684 - The default keep-alive timeout has been reduced to 5 seconds to work
2685 around hangs in clients that treat the proxy like any other host and
2686 stop allowing any new connections if the "maximum number of
2687 connections per host" is reached.
2688 - Several webbug URLs that look like they are leading to images are now
2689 blocked as image instead of empty documents. Doing the latter causes
2690 WebKit-based clients to show a "missing image" icon which may mess up
2692 - The no-such-domain template is used for DNS resolution
2693 problems with FEATURE_IPV6_SUPPORT enabled. Previously the
2694 connect-failed template was used. Reported by 'zebul666'.
2695 - Accepts quoted expiration dates even though RFC 2109 10.1.2
2696 doesn't seem to allow them. Reported anonymously.
2697 - Don't try to forget connections if connection sharing is disabled.
2698 This wasn't a real problem but caused an unnecessary log message.
2699 - The still undocumented --enable-extended-host-patterns configure
2700 option has a better description.
2701 - Fixed an error message that would claim a write to the server
2702 failed when actually writing to the client failed.
2703 - Log the crunch reason before trying to write to the client.
2704 The log is easier to read that way.
2705 - Several log messages about client connections also mention
2707 - handle-as-empty-document no longer depends on the image blocking
2709 - Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
2710 - uagen, a Firefox User-Agent generator for Privoxy and Mozilla
2711 browsers has been imported and is available in the tarball's
2713 - The scripts in the tools directory treat unknown parameters
2716 *** Version 3.0.15 beta ***
2718 - In case of missing server data, no error message is send to the
2719 client if the request arrived on a reused connection. The client
2720 is then supposed to silently retry the request without bothering
2721 the user. This should significantly reduce the frequency of the
2722 "No server or forwarder data received" error message many users
2724 - More reliable detection of prematurely closed client sockets
2725 with keep-alive enabled.
2726 - FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
2727 FEATURE_CONNECTION_SHARING and now available on
2729 - Improved handling of POST requests on reused connections.
2730 Should fix problems with stalled connections after submitting
2731 form data with some browser configurations.
2732 - Fixed various latency calculation issues.
2733 - Allows the client to pass NTLM authentication requests to a
2734 forwarding proxy. This was already assumed and hinted to work
2735 in 3.0.13 beta but actually didn't. Now it's confirmed to work
2736 with IE, Firefox and Chrome.
2737 Thanks to Francois Botha and Wan-Teh Chang
2738 - Fixed a calculation problem if receiving the server headers
2739 takes more than two reads, that could cause Privoxy to terminate
2740 the connection prematurely. Reported by Oliver.
2741 - Compiles again on platforms such as OpenBSD and systems
2742 using earlier glibc version that don't support AI_ADDRCONFIG.
2743 Anonymously submitted in #2872591.
2744 - A bunch of MS VC project files and Suse and Redhat RPM spec
2745 files have been removed as they were no longer maintained for
2747 - Overly long action lines are properly rejected with a proper
2748 error message. Previously they would be either rejected as
2749 invalid or cause a core dump through abort().
2750 - Already timed-out connections are no longer temporarily remembered.
2751 They weren't reused anyway, but wasted a socket slot.
2752 - len refers to the number of bytes actually read which might
2753 differ from the ones received. Adjust log messages accordingly.
2754 - The optional JavaScript on the CGI page uses encodeURIComponent()
2755 instead of escape() which doesn't encode all characters that matter.
2756 Anonymously reported in #2832722.
2757 - Fix gcc45 warnings in decompress_iob().
2758 - Various log message improvements.
2759 - Privoxy-Regression-Test supports redirect tests.
2760 - Privoxy-Log-Parser can gather some connection statistics.
2762 *** Version 3.0.14 beta ***
2764 - The latency is taken into account when evaluating whether or not to
2765 reuse a connection. This should significantly reduce the number of
2766 connections problems several users reported.
2767 - If the server doesn't specify how long the connection stays alive,
2768 Privoxy errs on the safe side of caution and assumes it's only a second.
2769 - The error pages for connection timeouts or missing server data use a
2770 Last-Modified date in the past. Retry attempts are detected and Privoxy
2771 removes the If-Modified-Since header to prevent the server from responding
2772 with status code 304 in which case the client would reuse the error message.
2773 - Setting keep-alive-timeout to 0 disables keep-alive support. Previously
2774 Privoxy would claim to allow persistence but not reuse the connection.
2775 - Pipelined requests are less likely to be mistaken for the request
2776 body of the previous request. Note that Privoxy still has no real
2777 pipeline support and will either serialize pipelined requests or
2778 drop them in which case the client has to resent them.
2779 - Fixed a crash on some Windows versions when header randomization
2780 is enabled and the date couldn't be parsed.
2781 - Privoxy's keep-alive timeout for the current connection is reduced
2782 to the one specified in the client's Keep-Alive header.
2783 - For HTTP/1.1 requests, Privoxy implies keep-alive support by not
2784 setting any Connection header instead of using 'Connection: keep-alive'.
2785 - If the socket isn't reusable, Privoxy doesn't temporarily waste
2786 a socket slot to remember the connection.
2787 - If keep-alive support is disabled but compiled in, the client's
2788 Keep-Alive header is removed.
2789 - Fixed a bug on mingw32 where downloading large files failed if
2790 keep-alive support was enabled.
2791 - Fixed a bug that (at least theoretically) could cause log
2792 timestamps to be occasionally off by about a second.
2793 - No Proxy-Connection header if added if there already is one.
2794 - The configure script respects the $PATH variable when searching
2797 *** Version 3.0.13 beta ***
2799 - Added IPv6 support. Thanks to Petr Pisar who not only provided
2800 the initial patch but also helped a lot with the integration.
2801 - Added client-side keep-alive support.
2802 - The connection sharing code is only used if the connection-sharing
2804 - The max-client-connections option has been added to restrict
2805 the number of client connections below a value enforced by
2806 the operating system.
2807 - Fixed a regression reintroduced in 3.0.12 that could cause
2808 crashes on mingw32 if header date randomization was enabled.
2809 - Compressed content with extra fields couldn't be decompressed
2810 and would get passed to the client unfiltered. This problem
2811 has only be detected through statical analysis with clang as
2812 nobody seems to be using extra fields anyway.
2813 - If the server resets the Connection after sending only the headers
2814 Privoxy forwards what it got to the client. Previously Privoxy
2815 would deliver an error message instead.
2816 - Error messages in case of connection timeouts use the right
2818 - If spawning a child to handle a request fails, the client
2819 gets an error message and Privoxy continues to listen for
2820 new requests right away.
2821 - The error messages in case of server-connection timeouts or
2822 prematurely closed server connections are now template-based.
2823 - If zlib support isn't compiled in, Privoxy no longer tries to
2824 filter compressed content unless explicitly asked to do so.
2825 - In case of connections that are denied based on ACL directives,
2826 the memory used for the client IP is no longer leaked.
2827 - Fixed another small memory leak if the client request times out
2828 while waiting for client headers other than the request line.
2829 - The client socket is kept open until the server socket has
2830 been marked as unused. This should increase the chances that
2831 the still-open connection will be reused for the client's next
2832 request to the same destination. Note that this only matters
2833 if connection-sharing is enabled.
2834 - A TODO list has been added to the source tarball to give potential
2835 volunteers a better idea of what the current goals are. Donations
2836 are still welcome too: https://www.privoxy.org/faq/general.html#DONATE
2838 *** Version 3.0.12 ***
2840 - The socket-timeout option now also works on platforms whose
2841 select() implementation modifies the timeout structure.
2842 Previously the timeout was triggered even if the connection
2843 didn't stall. Reported by cyberpatrol.
2844 - The Connection: keep-alive code properly deals with files
2845 larger than 2GB. Previously the connection was closed too
2847 - The content length for files above 2GB is logged correctly.
2848 - The user-manual directive on the show-status page links to
2849 the documentation location specified with the directive,
2850 not to the Privoxy website.
2851 - When running in daemon mode, Privoxy doesn't log anything
2852 to the console unless there are errors before the logfile
2854 - The show-status page prints warnings about invalid directives
2855 on the same line as the directives themselves.
2856 - Fixed several justified (but harmless) compiler warnings,
2857 mostly on 64 bit platforms.
2858 - The mingw32 version explicitly requests the default charset
2859 to prevent display problems with some fonts available on more
2860 recent Windows versions. Patch by Burberry.
2861 - The mingw32 version uses the Privoxy icon in the alt-tab
2862 windows. Patch by Burberry.
2863 - The timestamp and the thread id is omitted in the "Fatal error"
2864 message box on mingw32.
2865 - Fixed two related mingw32-only buffer overflows. Triggering
2866 them required control over the configuration file, therefore
2867 this isn't seen as a security issue.
2868 - In verbose mode, or if the new option --show-skipped-tests
2869 is used, Privoxy-Regression-Test logs skipped tests and the
2872 *** Version 3.0.11 ***
2874 - On most platforms, outgoing connections can be kept alive and
2875 reused if the server supports it. Whether or not this improves
2876 things depends on the connection.
2877 - When dropping privileges, membership in supplementary groups
2878 is given up as well. Not doing that can lead to Privoxy running
2879 with more rights than necessary and violates the principle of
2880 least privilege. Users of the --user option are advised to update.
2881 Thanks to Matthias Drochner for reporting the problem,
2882 providing the initial patch and testing the final version.
2883 - Passing invalid users or groups with the --user option
2884 didn't lead to program exit. Regression introduced in 3.0.7.
2885 - The match all section has been moved from default.action
2886 to a new file called match-all.action. As a result the
2887 default.action no longer needs to be touched by the user
2888 and can be safely overwritten by updates.
2889 - The standard.action file has been removed. Its content
2890 is now part of the default.action file.
2891 - In some situations the logged content length was slightly too low.
2892 - Crunched requests are logged with their own log level.
2893 If you used "debug 1" in the past, you'll probably want
2894 to additionally enable "debug 1024", otherwise only passed
2895 requests will be logged. If you only care about crunched
2896 requests, simply replace "debug 1" with "debug 1024".
2897 - The crunch reason has been moved to the beginning of the
2898 crunch message. For HTTP URLs, the protocol is logged as well.
2899 - Log messages are shortened by printing the thread id on its
2900 own (as opposed to putting it inside the string "Privoxy()").
2901 - The config option socket-timeout has been added to control
2902 the time Privoxy waits for data to arrive on a socket.
2903 - Support for remote toggling is controlled by the configure
2904 option --disable-toggle only. In previous versions it also
2905 depended on the action editor and thus configuring with the
2906 --disable-editor option would disable remote toggling support
2908 - Requests with invalid HTTP versions are rejected.
2909 - The template symbol @date@ can be used to include a date(1)-like
2910 time string. Initial patch submitted by Endre Szabo.
2911 - Responses from shoutcast servers are accepted again.
2912 Problem reported and fix suggested by Stefan.
2913 - The hide-forwarded-for-headers action has been replaced with
2914 the change-x-forwarded-for{} action which can also be used to
2915 add X-Forwarded-For headers. The latter functionality already
2916 existed in Privoxy versions prior to 3.0.7 but has been removed
2917 as it was often used unintentionally (by not using the
2918 hide-forwarded-for-headers action).
2919 - A "clear log" view option was added to the mingw32 version
2920 to clear out all of the lines in the Privoxy log window.
2921 Based on a patch submitted by T Ford.
2922 - The mingw32 version uses "critical sections" now, which prevents
2923 log message corruption under load. As a side effect, the
2924 "no thread-safe PRNG" warning could be removed as well.
2925 - The mingw32 version's task bar icon is crossed out and
2926 the color changed to gray if Privoxy is toggled off.
2928 *** Version 3.0.10 ***
2930 - Ordinary configuration file changes no longer cause program
2931 termination on OS/2 if the name of the logfile hasn't been
2932 changed as well. This regression probably crept in with the
2933 logging improvements in 3.0.7. Reported by Maynard.
2934 - The img-reorder filter is less likely to mess up JavaScript code in
2935 img tags. Problem and solution reported by Glenn Washburn in #2014552.
2936 - The source tar ball now includes Privoxy-Log-Parser,
2937 a syntax-highlighter for Privoxy logs. For fancy screenshots see:
2938 http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
2939 Documentation is available through perldoc(1).
2941 *** Version 3.0.9 beta ***
2943 - Added SOCKS5 support (with address resolution done by
2944 the SOCKS5 server). Patch provided by Eric M. Hopper.
2945 - The "blocked" CGI pages include a block reason that was
2946 provided as argument to the last-applying block action.
2947 - If enable-edit-actions is disabled (the default since 3.0.7 beta)
2948 the show-status page hides the edit buttons and explains why.
2949 Previously the user would get the "this feature has been disabled"
2950 message after using the edit button.
2951 - Forbidden CONNECT requests are treated like blocks by default.
2952 The now-pointless treat-forbidden-connects-like-blocks action
2954 - Not enabling limit-connect now allows CONNECT requests to all ports.
2955 In previous versions it would only allow CONNECT requests to port 443.
2956 Use +limit-connect{443} if you think you need the old default behaviour.
2957 - The CGI editor gets turned off after three edit requests with invalid
2958 file modification timestamps. This makes life harder for attackers
2959 who can leverage browser bugs to send fake Referers and intend to
2960 brute-force edit URLs.
2961 - Action settings for multiple patterns in the same section are
2962 shared in memory. As a result these sections take up less space
2963 (and are loaded slightly faster). Problem reported by Franz Schwartau.
2964 - Linear white space in HTTP headers will be normalized to single
2965 spaces before parsing the header's content, headers split across
2966 multiple lines get merged first. This should prevent problems like:
2967 * letting the session-cookies-only action slip
2968 some Cookies through unmodified,
2969 * only suppressing the first line of a header,
2970 thus creating an invalid one, and
2971 * to incorrectly block headers with valid timestamps
2972 that weren't properly recognized.
2973 Headers that could trigger these problems are unlikely to appear
2974 in "normal" web traffic, but could be intentionally generated to
2975 fool some of Privoxy's header parsers.
2976 - Host information is gathered outside the main thread so it's less
2977 likely to delay other incoming connections if the host is misconfigured.
2978 - New config option "hostname" to use a hostname other than
2979 the one returned by the operating system. Useful to speed-up responses
2980 for CGI requests on misconfigured systems. Requested by Max Khon.
2981 - The CGI editor supports the "disable all filters of this type"
2982 directives "-client-header-filter", "-server-header-filter",
2983 "-client-header-tagger" and "-server-header-tagger".
2984 - Fixed false-positives with the link-by-url filter and URLs that
2985 contain the pattern "/jump/".
2986 - The less-download-windows filter no longer messes
2987 "Content-Type: application/x-shockwave-flash" headers up.
2988 - In the show-url-info page's "Final results" section active and
2989 inactive actions are listed separately. Patch provided by Lee.
2990 - The GNUmakefile supports the DESTDIR variable. Patch for
2991 the install target submitted by Radoslaw Zielinski.
2992 - Embedding the content of configuration files in the show-status
2993 page is significantly faster now. For a largish action file (1 MB)
2994 a speedup of about 2450 times has been measured. This is mostly
2995 interesting if you are using large action files or regularly use
2996 Privoxy-Regression-Test while running Privoxy through Valgrind,
2997 for stock configuration files it doesn't really matter.
2998 - If zlib support is unavailable and there are content
2999 filters active but the prevent-compression action is disabled,
3000 the show-url-info page includes a warning that compression
3001 might prevent filtering.
3002 - The show-url-info page provides an OpenSearch Description that
3003 allows to access the page through browser search plugins.
3004 - Custom client-header filters that rewrite the request line
3005 incorrectly no longer cause Privoxy to crash. Reported by din_a4.
3006 - The obsolete kill-popups action has been removed as the
3007 PCRS-based popup filters can do the same and are slightly
3009 - The inspect-jpegs action has been removed.
3010 - The send-wafer and send-vanilla-wafer actions have been removed.
3011 They weren't particular useful and their behaviour could be emulated
3012 with add-header anyway.
3013 - Privoxy-Regression-Test has been significantly improved.
3014 - Most sections in the default.action file contain tests for
3015 Privoxy-Regression-Test to verify that they are working as intended.
3016 - Parts of Privoxy have been refactored to increase maintainability.
3017 - Building with zlib (if available) is done by default.
3019 *** Version 3.0.8 ***
3021 - Fixed a small memory leak when listen-address only specifies the port.
3022 - The source tar balls now include Privoxy-Regression-Test which
3023 (upon other things) can be used to automatically detect some
3024 packaging problems. Packagers are welcome to give it a try.
3025 - Reverted a change in 3.0.7 that caused path patterns to be checked
3026 even if the host pattern match already failed. While this doesn't
3027 noticeable affect the performance, it makes it less likely to run
3028 out of stack space with overly-complex path patterns the user might
3030 - Updated the msn, yahoo and google filters to work as advertised again.
3031 - The warning message shown by the show-status CGI page is easier to
3032 understand. Previously it wasn't clear that the error message
3033 is shown below the invalid directive. (Reported by Lee)
3034 - When regenerating Content-Disposition headers the more common
3035 spelling is used for the name. Previously it was written without caps.
3036 - Less confusing log message if the content type isn't overwritten
3037 because force-text-type wasn't used but the old type doesn't look
3038 like content that would be filtered normally.
3039 - Better log messages if the user tries to execute filters that
3041 - Treat the non-standard Request-Range headers like standard range
3042 headers and suppress them if content filtering is enabled.
3043 - Prevent the log messages for CONNECT requests to unacceptable
3044 ports from printing the limit-connect argument as [null] if
3045 limit-connect hasn't been explicitly enabled.
3046 - Don't disable the mingw32 log window if the logfile directive
3047 isn't used. While it was an intentional change in 3.0.7 at least
3048 one user perceived it as a regression and the same effect can
3049 be achieved by disabling all debug directives.
3050 - Fixed two minor problems related to the win32 build process: a css
3051 file was not being in the installer and the trustfile comment in the
3052 config.txt referenced a nonexisting file
3053 - Minor documentation fixes.
3055 *** Version 3.0.7 beta ***
3057 - Added zlib support to filter content with gzip and deflate
3058 encoding. (Patch provided by Wil Mahan)
3059 - Dedicated filters and actions are used for header filtering.
3060 "filter-client-headers" and "filter-client-headers" are no longer
3061 supported, use server-header-filter{} and client-header-filter{}
3063 - Tags can be used to change actions based on HTTP headers.
3064 - New server-header filter: less-download-windows.
3065 - New client-header taggers: css-requests, image-requests,
3066 client-ip-address, http-method, allow-post, complete-url,
3067 user-agent and privoxy-control.
3068 - New server-header taggers: content-type and privoxy-control.
3069 - The forward-override{} action allows to change the forwarding
3070 settings through the action files, for example based on client
3071 headers like the User-Agent, or the request origin.
3072 - Socks errors are no longer handled by the CGI page for
3073 DNS resolution failures.
3074 - CGI pages use favicons to signal whether they are error
3075 or control pages. This is useful if you rely heavily on
3077 - The show-url-info CGI page shows the forwarding settings.
3078 - "Crunch!" log messages (used when Privoxy answers requests
3079 by itself) now also contain the reason.
3080 - Allow to rewrite the request destination behind the client's back.
3081 - Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
3082 - Fixes possible deadlocks and crashes on OpenBSD.
3083 Patch provided by Ralf Horstmann.
3084 - The CGI action editor allows to edit actionfiles with previously
3085 forbidden characters like dots.
3086 - New trust entries are saved with a comment that contains the
3087 trusted referring URL (Suggested by Daniel Griscom).
3088 - Filter descriptions are HTML encoded automatically.
3089 - New config option "split-large-forms" to work
3090 around a browser bug that caused IE6 and IE7 to ignore
3091 the Submit button on the edit-actions-for-url CGI page.
3092 - New config option "allow-cgi-request-crunching" to allow
3093 requests for Privoxy's CGI pages to be blocked, redirected
3094 or (un)trusted like ordinary requests.
3095 - Empty filter files no longer interrupt the filtering process
3096 prematurely and are correctly listed on the show-status CGI page.
3097 - New config option "accept-intercepted-requests" to combine
3098 Privoxy with any packet filter to build an intercepting proxy
3099 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
3100 - fast-redirects{} catch redirects to https URLs as well.
3101 - redirect{s@foo@bar@} can be used to redirect to a rewritten
3102 version of the original URL.
3103 - Trap unsupported gopher proxy requests.
3104 - Fixed a bug in the User Manual delivery on Windows
3105 (mingw32 only). Images now show up correctly and HTML
3106 pages are no longer padded with garbage data.
3107 - Fixed several minor memory leaks, most of them discovered with Valgrind.
3108 - Only unlink the pidfile if it's actually used.
3109 - Retries after connection problems with forced requests
3110 aren't blocked again.
3111 - On Unix SIGABRT causes a core dump as expected and is no
3112 longer treated as normal shutdown signal.
3113 - The "access denied" CGI page is more descriptive and
3114 allows retries to circumvent the referrer check.
3115 - Updated PCRS to handle unexpected PCRE errors properly.
3116 Fixed crashes that could occur if Privoxy was build
3117 with external PCRE versions newer than Privoxy's internal
3118 one. (Reported by Chung-chieh Shan)
3119 - Fixed crashes with null bytes in PCRS replacement strings
3120 (Patch provided by Felix Gröbert).
3121 - Fixed crashes with header time randomization on mingw32.
3122 - The CGI style sheet is no longer delivered if the referring
3123 page isn't a Privoxy CGI page. This prevents a JavaScript-based
3124 Privoxy detection "attack". Note that detecting Privoxy is
3125 still possible through other ways and Privoxy was never intended
3126 to be invisible anyway.
3127 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
3128 - The show-url-info CGI page displays a warning if Privoxy
3129 is currently toggled off.
3130 - The show-status CGI page suppresses the edit button
3131 for action files if Privoxy has no write access.
3132 - Most CGI error pages react properly to HEAD requests.
3133 - Requests with RFC 3253 HTTP methods (used by Subversion)
3134 are accepted. (Patch provided by Petr Kadlec)
3135 - New config option "templdir" to change the location
3136 of the CGI templates to make sure customized templates
3138 - Better handling of "HTTP/1.1 100 Continue" responses.
3139 - The background of the PNG pattern is transparent.
3140 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
3141 - Fixed crashes and possible action file corruptions
3142 when lines containing hashes are written through the CGI editor.
3143 - Supports dynamic filters which can contain variables.
3144 - Supports tags to change the actions based on client or server headers.
3145 - Incorrect actions are logged before program termination.
3146 - The "actionsfile" syntax in the configuration file is consistent
3147 with the rest of the configuration options and requires the
3148 whole file name. This is an incompatible change, if you use
3149 an old configuration file you might have to append ".action"
3150 to your "actionsfile" directives.
3151 - With the configuration file option "enforce-blocks" the
3152 "go there anyway" mechanism can be disabled without recompiling
3154 - More precise error messages in case of incorrect acl syntax.
3155 - Logs a warning if filtering is enabled but impossible due
3156 to lack of zlib support or use of the prevent-compression action.
3157 - Less noisy handling of Cookie:" and "Connection:" headers.
3158 - Improved error messages in case of connection problems.
3159 - Fix a command-line-parsing bug that was introduced before 3.0.5
3160 beta and caused Privoxy to treat the last argument as configuration
3161 file if no configuration file was specified.
3162 - Treat unknown command line options as fatal errors instead
3163 of silently ignoring them.
3164 - Use string functions with length checks more often.
3165 - Don't log CONNECT requests twice.
3166 - Allow to log the source address for ACL-related connection drops.
3167 - Don't ignore applying filters if the server didn't
3168 specify a Content-Type. Bug reported by Amuro Namie.
3169 - Rejected CONNECT requests are logged with log level info
3170 (enabled by default) and the reason for the block.
3171 - New command line option "--pre-chroot-nslookup hostname" to
3172 intialize the resolver library before chroot'ing. On some systems this
3173 reduces the number of files that must be copied into the chroot tree.
3174 (Patch provided by Stephen Gildea)
3175 - Fix a long-standing memory corruption bug that could cause
3176 Privoxy to overwrite a single byte in memory it didn't explicitly
3177 allocate (but that probably was allocated anyway due to bucket size).
3178 - Send template-based CGI pages as HTTP/1.1 unless the client
3180 - Let the first line in connection established responses
3181 end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
3182 - If no log file has been specified, disable logging instead of logging
3184 - Don't block stderr when in daemon mode.
3185 - Ignore missing zero-chunks when filtering chunk-encoded content.
3186 Earlier Privoxy versions would buffer and then forward the content
3187 unmodified which caused some browsers to simply show empty pages.
3188 - Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
3189 - The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
3190 action isn't being used has been removed.
3191 - Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
3193 - Minor code clean-ups, filter and action file updates.
3194 (Some of them reported by Davide Alberani, Markus Elfring,
3195 Stefan Huehner and Adam Piggott)
3197 *** Version 3.0.6 ***
3199 - New content filters: no-ping, google, msn, yahoo and blogspot.
3200 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
3201 and hide-tor-exit-notation.
3202 - The special header "X-Filter: No" now disables header filtering as well.
3203 - Improved the filters img-reorder, js-annoyances, webbugs,
3204 banners-by-size, banners-by-link and ie-exploits to make them
3205 less likely to break anything.
3206 - Removed outdated URL patterns in default.action and added new ones.
3207 - Added redirection from http://p.p/user-manual to http://p.p/user-manual/
3208 - Changed webinterface default values for hide-user-agent, hide-referrer
3209 and set-image-blocker.
3211 *** Version 3.0.5 beta ***
3213 - Windows version can be installed/started as a service.
3214 - Windows icon stays blue when Privoxy is idle, green when busy.
3215 - Integrated Fabian Keil's extensive patch. See:
3216 http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
3217 following new or significantly improved actions (among many
3218 other improvements):
3220 content-type-overwrite{}
3221 crunch-client-header{string}
3222 crunch-if-none-match
3223 crunch-server-header{string}
3224 fast-redirects{check-decoded-url}
3225 filter-client-headers
3226 filter-server-headers
3228 handle-as-empty-document
3229 hide-accept-language{}
3230 hide-content-disposition{}
3231 hide-if-modified-since
3232 hide-referrer{conditional-block}
3233 overwrite-last-modified{}
3235 treat-forbidden-connects-like-blocks
3237 - Standard-compliant clients are prevented from displaying cached
3238 copies of Privoxy's error messages after the cause of the problem
3240 - Improved DNS error handling.
3241 - Multiple filter files can now be specified in config.
3242 - Added jpeg filtering to defend against MS jpeg vulnerability MS04-028
3243 with the new inspect-jpegs action.
3244 - Removed the "arbitrary" 1000 filter limit - addresses tracker #911950
3245 - Thanks to Jindrich Makovicka for a race condition fix for the log
3246 file. The race condition remains for non-pthread implementations.
3247 Reference patch #1175720. Various other logging enhancements.
3248 - A pile of assorted bug fixes, memory leaks, enhancements, etc.
3249 - Moved Actions file reporting mechanism to SF tracker.
3250 - Two new options for config: enable-remote-http-toggle and
3251 forwarded-connect-retries.
3252 - Trap unsupported FTP requests.
3253 - Let text/xml be filtered.
3254 - Numerous updates to default.action
3255 - Increase the compiled in limit of trusted referrers from 64 to 512
3256 (for trustfile users).
3258 *** Version 3.0.3 ***
3260 - Fixed yet another two memory leaks. Process growth seems stopped now.
3261 - Further tightened security against malicious toggle-off links.
3262 - Excluded text/plain MIME types from filtering. This fixes a

3434 *** Version 2.9.3 pre-Alpha Changes ***
3436 - Amiga support (completely untested by me - I don't have an Amiga)
3437 - "tinygif 3" support (redirects blocked images to a specified URL, so
3438 the browser doesn't have to load and cache many copies of the same
3440 - one case where there were both local and global "referrer" variables
3441 (yuck!) clarified by renaming the local one to "refer".
3442 - Fixed some places where close() was used instead of close_socket().
3443 Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
3444 - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
3445 FORCE_LOAD_PREFIX. Needs fixing properly.
3446 - Most URLs hardcoded into Junkbuster were changed to go through a script
3447 e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
3448 The only other URLs left are the GNU GPL:
3449 http://www.fsf.org/copyleft/gpl.html
3451 http://ijbswa.sourceforge.net/
3452 ... and various URLs which will be intercepted by Junkbuster anyway.
3453 TODO: Still need to do something with the URLs in Junkbuster Corp's
3454 copyright/trademark notice on the bottom of the show-proxy-args page.
3455 - PCRE or GNU Regex is now a #define option.
3458 *** Version 2.9.2 pre-Alpha Changes ***
3460 - Andreas applied the latest version of the FORCE patch.
3463 *** Version 2.9.1 pre-Alpha Changes ***
3465 - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
3466 (BTW: I think FORCE is precise enough, since loading remote
3467 data is the whole purpose of a proxy..)
3468 - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
3469 is more elegant and looks like a hostname in the URL, it doesn't
3470 make clear to the inexperienced user that the proxy is bypassed. It
3471 also has a higher name collision risk.
3472 - Filled in the function header templates for my functions in
3473 parsers.c (again). They obviously got lost in our current
3475 - Cut the credit for the §-referrer-option from the config file,
3476 that Stefan had placed there.
3477 - Improved the re_filterfile
3480 *** Version 2.9.0 pre-Alpha Changes ***
3482 - Now use PCRE, not GNU REGEX. I have not yet had chance to check the
3483 syntax of the block/image/cookie file to ensure that they match what
3484 is expected - however they seem to work.
3485 - Replaced "configure" script with one generated by "autoconf". Also
3486 use a header "config.h" (was ijbconfig.h in my previous release) for
3487 the #defines. "config.h" is now generated with "autoheader" from
3488 "acconfig.h" and "configure.in". (Note that to install you do not
3489 need autoconf or autoheader - just run "./configure".)
3490 To see command-line options, run "./configure --help".
3491 This is my first ever autoconf script, so it has some rough edges
3492 (how PCRE is handled is the roughest).
3493 - Error logging code replaced with new module errlog.c, based on the
3494 one from JunkbusterMT (but with the threading code removed).
3495 - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
3496 apply all of these, since I had already independently done conditional
3497 popup file, conditional image file, and integration of popup code.
3498 - ACL, Jar and trust files conditionally compiled.
3499 - New source file headers.
3500 - Various cosmetic changes. (But I have not consistently ordered the
3501 config files - I think that's worthwhile, but it's 1am and I want to
3503 - RCS tags on .h files.
3504 - RCS tags are const char[] rather than const char *. (Saves 4 bytes
3506 - VC++ project files renamed to vc_junkbuster.*.
3507 - show-proxy-args now shows status of all conditionals, not just REGEX
3508 - Various functions moved around. Most notably all the system-specific
3509 sockets code which was spread between jcc.c, bind.c, and connect.c,
3510 has been moved to "jbsockets.c". The non-system-specific code from
3511 connect.c and socks4.c has been movet to "gateway.c". Also, the
3512 config file loader and the global variables it writes to have been
3513 moved to "loadcfg.c". (Maybe this should go into loaders.c?)
3514 And candidate for the "worst filename ever" award is "miscutil.c",
3515 which contains, well, miscellaneous utility functions like zalloc.
3516 (Suggestions for a better name for this file are welcome!)
3517 - Loaders now use a common function to read a line and skip comments,
3518 and this function also stores the proxy_args.
3519 - Added ./junkbuster --help (Not for Win32 GUI)
3520 - Added ./junkbuster --version (Not for Win32 GUI)
3521 - Win32 resources are now all marked as "U.S. English", rather than
3522 being a mix of "U.S. English", "U.K. English" and "Irish English".
3523 - Version number changes to 2.9.0
