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 - Add HTTPS inspection support using OpenSSL 3.0.7
123 - Add OpenSSL to the list of libraries that may be licensed under the
124 Apache 2.0 license in which case the linked Privoxy binary has to be
125 distributed under the GPLv3 or later.
126 - config: Fix the documented ca-directory default value
128 - Rebuild developer-manual and tidy with 'HTML Tidy for FreeBSD version 5.8.0'
129 - Update developer manual with new macOS packaging instructions.
131 *** Version 3.0.33 stable ***
132 - Security/Reliability:
133 - cgi_error_no_template(): Encode the template name to prevent
134 XSS (cross-site scripting) when Privoxy is configured to servce
135 the user-manual itself.
136 Commit 0e668e9409c. OVE-20211102-0001. CVE-2021-44543.
137 Reported by: Artem Ivanov
138 - get_url_spec_param(): Free memory of compiled pattern spec
140 Reported by Joshua Rogers (Opera) who also provided the fix.
141 Commit 652b4b7cb0. OVE-20211201-0003. CVE-2021-44540.
142 - process_encrypted_request_headers(): Free header memory when
143 failing to get the request destination.
144 Reported by Joshua Rogers (Opera) who also provided the fix.
145 Commit 0509c58045. OVE-20211201-0002. CVE-2021-44541.
146 - send_http_request(): Prevent memory leaks when handling errors
147 Reported by Joshua Rogers (Opera) who also provided the fix.
148 Commit c48d1d6d08. OVE-20211201-0001. CVE-2021-44542.
151 - handle_established_connection(): Skip the poll()/select() calls
152 if TLS data is pending on the server socket. The TLS library may
153 have already consumed all the data from the server response in
154 which case poll() and select() will not detect that data is
155 available to be read.
156 Fixes SF bug #926 reported by Wen Yue.
157 - continue_https_chat(): Update csp->server_connection.request_sent
158 after sending the request to make sure the latency is calculated
159 correctly. Previously https connections were not reused after
160 timeout seconds after the first request made on the connection.
161 - free_pattern_spec(): Don't try to free an invalid pointer
162 when unloading an action file with a TAG pattern while
163 Privoxy has been compiled without FEATURE_PCRE_HOST_PATTERNS.
164 Closes: SF patch request #147. Patch by Maxim Antonov.
165 - Adjust build_request_line() to create a CONNECT request line when
166 https-inspecting and forwarding to a HTTP proxy.
167 Fixes SF bug #925 reported by Wen Yue.
168 - load_config(): Add a space that was missing in a log message.
169 - read_http_request_body(): Fix two error messages that used an
171 - If the the response is chunk-encoded, ignore the Content-Length
172 header sent by the server.
173 Allows to load https://redmine.lighttpd.net/ with filtering enabled.
175 - General improvements:
176 - Allow to edit the add-header action through the CGI editor by
177 generalizing the code that got added with the suppress-tag action.
178 Closes SF patch request #146. Patch by Maxim Antonov.
179 - Add a CGI handler for /wpad.dat that returns a
180 Proxy Auto-Configuration (PAC) file.
181 Among other things, it can be used to instruct clients
182 through DHCP to use Privoxy as proxy.
183 For example with the dnsmasq option:
184 dhcp-option=252,http://config.privoxy.org/wpad.dat
185 Initial patch by Richard Schneidt.
186 - Don't log the applied actions in process_encrypted_request()
187 Log them in continue_https_chat() instead to mirror chat().
188 Prevents the applied actions from getting logged twice
189 for the first request on an https-inspected connection.
190 - OpenSSL generate_host_certificate(): Use config.privoxy.org as Common Name
191 Org and Org Unit if the real host name is too long to get accepted by OpenSSL.
192 Clients should only care about the Subject Alternative Name
193 anyway and we can continue to use the real host name for it.
194 Reported by Miles Wen on privoxy-users@.
195 - Establish the TLS connection with the client earlier and decide
196 how to route the request afterwards. This allows to change the
197 forwarding settings based on information from the https-inspected
198 request, for example the path.
199 - listen_loop(): When shutting down gracefully, close listening ports
200 before waiting for the threads to exit. Allows to start a second
201 Privoxy with the same config file while the first Privoxy is still
203 - serve(): Close the client socket as well if the server socket
204 for an inspected connection has been closed. Privoxy currently
205 can't establish a new server connection when the client socket
206 is reused and would drop the connection in continue_https_chat()
208 - Don't disable redirect checkers in redirect_url().
209 Disable them in handle_established_connection() instead.
210 Doing it in redirect_url() prevented the +redirect{} and
211 +fast-redirects{} actions from being logged with LOG_LEVEL_ACTIONS.
212 - handle_established_connection(): Slightly improve a comment.
213 - handle_established_connection(): Fix a comment.
214 - socks5_connect(): Fix indentation.
215 - handle_established_connection(): Improve an error message.
216 - create_pattern_spec(): Fix ifdef indentation.
218 - process_encrypted_request(): Improve a log message.
219 The function only processes request headers and there
220 may still be unread request body data left to process.
221 - chat(): Log the applied actions before deciding how to forward the request.
222 - parse_time_header(): Silence a coverity complaint when building without assertions.
223 - receive_encrypted_request_headers(): Improve a log message.
224 - mbedTLS get_ciphersuites_from_string(): Use strlcpy() instead of strncpy().
225 Previously the terminating NUL wasn't copied which resulted
226 in a compiler warning. This didn't cause actual problems as
227 the target buffer was initialized by zalloc_or_die() so the
228 last byte of the target buffer was NUL already.
229 Actually copying the terminating NUL seems clearer, though.
230 - Remove compiler warnings. "log_error(LOG_LEVEL_FATAL, ..."
231 doesn't return but apparently the compiler doesn't know that.
232 Get rid of several "this statement may fall through
233 [-Wimplicit-fallthrough=]" warnings.
234 - Store the PEM certificate in a dynamically allocated buffer
235 when https-inspecting. Should prevent errors like:
236 2021-03-16 22:36:19.148 7f47bbfff700 Error: X509 PEM cert len 16694 is larger than buffer len 16383
237 As a bonus it should slightly reduce the memory usage as most
238 certificates are smaller than the previously used fixed buffer.
240 - OpenSSL generate_host_certificate(): Fix two error messsages.
241 - Improve description of handle_established_connection()
242 - OpenSSL ssl_store_cert(): Translate EVP_PKEY_EC to a string.
243 - OpenSSL ssl_store_cert(): Remove pointless variable initialization.
244 - OpenSSL ssl_store_cert(): Initialize pointer with NULL instead of 0.
246 - Action file improvements:
247 - Disable fast-redirects for .microsoftonline.com/.
248 - Disable fast-redirects for idp.springer.com/.
249 - Disable fast-redirects for .zeit.de/zustimmung.
250 - Unblock adv-archiv.dfn-cert.de/.
251 - Block requests to eu-tlp01.kameleoon.eu/.
252 - Block requests to fpa-events.arstechnica.com/.
254 - Unblock adguard.com/.
256 - Privoxy-Log-Parser:
257 - Highlight 'Socket timeout 3 reached: http://127.0.0.1:20000/no-filter/chunked-content/36'.
258 - Improve documentation for inactivity-detection mode.
259 - Detect date changes when looking for inactivity.
260 - Add a --passed-request-statistics-threshold option
261 that can be set to get statistics for requests that
263 - Add a "inactivity detection" mode which can be useful
264 for debugging purposes.
265 - Bump version to 0.9.4.
266 - Only run print_intro() and print_outro() when syntax highlighting.
267 - Rephrase a sentence in the documentation.
268 - Highlight 'Client socket 7 is no longer usable. The server socket has been closed.'.
269 - Clarify --statistics output by explicitly mentioning that
270 the status codes sent by the server may differ from the ones
271 in "debug 512" messages.
272 - Fix typo in the --statistics output.
273 - Remove an unused variable.
274 - Highlight 'The peer notified us that the connection on socket 11 is going to be closed'.
276 - Privoxy-Regression-Test:
277 - Remove duplicated word in a comment.
279 - regression-tests.action:
280 - Add fetch test for http://p.p/wpad.dat.
281 - Bump for-privoxy-version to 3.0.33 which introduced the wpad.dat support.
282 - Add more tests for the '/send-banner' code.
283 - Add test for OVE-20210203-0001.
284 - Add a test for CVE-2021-20217.
287 - Bump generated Firefox version to 91 (ESR).
288 - Bump version to 1.2.3.
292 - configure: Bump SOURCE_DATE_EPOCH.
293 - GNUmakefile.in: Fix typo.
294 - configure: Add another warning in case --disable-pthread
295 is used while POSIX threads are available.
296 Various features don't even compile when not using threads.
297 - Add configure option to enable MemorySanitizer.
298 - Add configure option to enable UndefinedBehaviorSanitizer.
299 - Add configure option to enable AddressSanitizer.
301 - Add a configure option to disable pcre JIT compilation.
302 While JIT compilation makes filtering faster it can
303 cause false-positive valgrind complaints.
304 As reported by Gwyn Ciesla in SF bug 924 it also can
305 cause problems when the SELinux policy does not grant
306 Privoxy "execmem" privileges.
307 - configure: Remove obsolete RPM_BASE check.
309 - Windows build system:
310 - Update the build script to use mbed tls version 2.6.11.
311 - Update build script to use the final 8.45 pcre library.
312 - Put all the '--enable-xxx' options in the configure call together.
314 - macOS build system:
315 - The OSXPackageBuilder repository has been updated and
316 can be used to create macOS packages again.
319 - contacting: Remove obsolete reference to announce.sgml.
320 - contacting: Request that the browser cache is cleared before
321 producing a log file for submission.
322 - Sponsor FAQ: Note that Privoxy users may follow sponsor links
323 without Referer header set.
324 - newfeatures: Clarify that https inspection also allows to
325 filter https responses.
326 - developer-manual: Mention that announce.txt should be updated
327 when doing a release.
328 - config: Explicitly mention that the CGI pages disclosing the
329 ca-password can be blocked and upgrade the disclosure paragraphs
331 - Put all the requested debug options in the config file.
332 Section 11.1 of the Privoxy user manual lists all the debug
333 options that should be enabled when reporting problems or requesting support.
334 Make it easier for users to do the right thing by having all those
335 options present in the config.
336 - Update TODO list item #184 to note that WolfSSL support will
337 (hopefully) appear after the 3.0.34 release.
338 - Update max-client-connections's description.
339 On modern systems other than Windows Privoxy should
340 use poll() in which case the FD_SETSIZE value isn't
342 - Add a warning that the socket-timeout does not apply
343 to operations done by TLS libraries.
344 - Make documentation slightly less "offensive" for some people
345 by avoiding the word "hell".
347 *** Version 3.0.32 stable ***
349 - Security/Reliability:
350 - ssplit(): Remove an assertion that could be triggered with a

353 Reported by: Joshua Rogers (Opera)
354 - cgi_send_banner(): Overrule invalid image types. Prevents a
355 crash with a crafted CGI request if Privoxy is toggled off.
356 Commit e711c505c48. OVE-20210206-0001. CVE-2021-20273.
357 Reported by: Joshua Rogers (Opera)
358 - socks5_connect(): Don't try to send credentials when none are
359 configured. Fixes a crash due to a NULL-pointer dereference
360 when the socks server misbehaves.
361 Commit 85817cc55b9. OVE-20210207-0001. CVE-2021-20274.
362 Reported by: Joshua Rogers (Opera)
363 - chunked_body_is_complete(): Prevent an invalid read of size two.
364 Commit a912ba7bc9c. OVE-20210205-0001. CVE-2021-20275.
365 Reported by: Joshua Rogers (Opera)
366 - Obsolete pcre: Prevent invalid memory accesses with an invalid
367 pattern passed to pcre_compile(). Note that the obsolete pcre code
368 is scheduled to be removed before the 3.0.33 release. There has been
369 a warning since 2008 already.
370 Commit 28512e5b624. OVE-20210222-0001. CVE-2021-20276.
371 Reported by: Joshua Rogers (Opera)
374 - Properly parse the client-tag-lifetime directive. Previously it was
375 not accepted as an obsolete hash value was being used.
376 Reported by: Joshua Rogers (Opera)
377 - decompress_iob(): Prevent reading of uninitialized data.
378 Reported by: Joshua Rogers (Opera).
379 - decompress_iob(): Don't advance cur past eod when looking
380 for the end of the file name and comment.
381 - decompress_iob(): Cast value to unsigned char before shifting.
382 Prevents a left-shift of a negative value which is undefined behaviour.
383 Reported by: Joshua Rogers (Opera)
384 - gif_deanimate(): Confirm that that we have enough data before doing
385 any work. Fixes a crash when fuzzing with an empty document.
386 Reported by: Joshua Rogers (Opera).
387 - buf_copy(): Fail if there's no data to write or nothing to do.
388 Prevents undefined behaviour "applying zero offset to null pointer".
389 Reported by: Joshua Rogers (Opera)
390 - log_error(): Treat LOG_LEVEL_FATAL as fatal even when --stfu is
391 being used while fuzzing.
392 Reported by: Joshua Rogers (Opera).
393 - Respect DESTDIR when considering whether or not to install
394 config files with ".new" extension.
395 - OpenSSL ssl_store_cert(): Fix two error messages.
396 - Fix a couple of format specifiers.
397 - Silence compiler warnings when compiling with NDEBUG.
398 - fuzz_server_header(): Fix compiler warning.
399 - fuzz_client_header(): Fix compiler warning.
400 - cgi_send_user_manual(): Also reject requests if the user-manual
401 directive specifies a https:// URL. Previously Privoxy would try and
402 fail to open a local file.
404 - General improvements:
405 - Log the TLS version and the the cipher when debug 2 is enabled.
406 - ssl_send_certificate_error(): Respect HEAD requests by not sending a body.
407 - ssl_send_certificate_error(): End the body with a single new line.
408 - serve(): Increase the chances that the host is logged when closing
410 - handle_established_connection(): Add parentheses to clarify an expression
411 Suggested by: David Binderman
412 - continue_https_chat(): Explicitly unset CSP_FLAG_CLIENT_CONNECTION_KEEP_ALIVE
413 if process_encrypted_request() fails. This makes it more obvious that the
414 connection will not be reused. Previously serve() relied on
415 CSP_FLAG_SERVER_CONTENT_LENGTH_SET and CSP_FLAG_CHUNKED being unset.
416 Inspired by a patch from Joshua Rogers (Opera).
417 - decompress_iob(): Add periods to a couple of log messages
418 - Terminate the body of the HTTP snipplets with a single new line
420 - configure: Add --with-assertions option and only enable assertions
422 - windows build: Use --with-brotli and --with-mbedtls by default and
423 enable dynamic error checking.
424 - gif_deanimate(): Confirm we've got an image before trying to write it
425 Saves a pointless buf_copy() call.
426 - OpenSSL ssl_store_cert(): Remove a superfluous space before the serial number.
428 - Action file improvements:
429 - Disable fast-redirects for .golem.de/
430 - Unblock requests to adri*.
431 - Block requests for trc*.taboola.com/
432 - Disable fast-redirects for .linkedin.com/
434 - Filter file improvements:
435 - Make the second pcrs job of the img-reorder filter greedy again.
436 The ungreedy version broke the img tags on:
437 https://bulk.fefe.de/scalability/.
439 - Privoxy-Log-Parser:
440 - Highlight a few more messages.
441 - Clarify the --statistics output. The shown "Reused connections"
442 are server connections so name them appropriately.
443 - Bump version to 0.9.3.
445 - Privoxy-Regression-Test:
446 - Add the --check-bad-ssl option to the --help output.
447 - Bump version to 0.7.3.
450 - Add pushing the created tag to the release steps in the developer manual.
451 - Clarify that 'debug 32768' should be used in addition to the other debug
452 directives when reporting problems.
453 - Add a 'Third-party licenses and copyrights' section to the user manual.
455 *** Version 3.0.31 stable ***
457 - Security/Reliability:
458 - Prevent an assertion from getting triggered by a crafted CGI request.
459 Commit 5bba5b89193fa. OVE-20210130-0001. CVE-2021-20217.
460 Reported by: Joshua Rogers (Opera)
461 - Fixed a memory leak when decompression fails "unexpectedly".
462 Commit f431d61740cc0. OVE-20210128-0001. CVE-2021-20216.
465 - Fixed detection of insufficient data for decompression.
466 Previously Privoxy could try to decompress a partly
467 uninitialized buffer.
469 *** Version 3.0.30 stable ***
472 - Check the actual URL for redirects when https inspecting requests.
473 Previously Privoxy would only check the path which resulted in
474 rewrite results being rejected as invalid URLs.
475 Reported by withoutname in #1736.
476 - Let the hide-referrer code tolerate Referer headers with https:// URLs.
477 Previously they would always be treated like a changed host.
478 - Use the https headers if the show-request handler is reached through
479 https://. Previously Privoxy would use the http headers which
480 may be empty on a reused connection.
481 - Make CGI_PREFIX protocol-relative when building with FEATURE_HTTPS_INSPECTION.
482 This unbreaks (at least) https://config.privoxy.org/client-tags whose
483 buttons would previously use a http:// URL resulting in browser warnings.
484 - Support using https-inspection and client-header-order at the same time.
485 Previously Privoxy would crash.
486 Reported by: Kai Raven
487 - Properly reject rewrites from http to https as they currently
488 aren't supported. Previously Privoxy would wait for the client
489 to establish an encrypted connection which obviously would not happen.
490 - When https inspection is enabled and Privoxy has been compiled with
491 FEATURE_GRACEFUL_TERMINATION (not recommended for production builds),
492 the TLS backend resources are free'd later on and only if no active
493 connections are left. Prevents crashes when exiting "gracefully" at the
495 - Let the uninstall target remove the config file even if DESTDIR
496 is set and properly announce the deletion of the configuration files.
498 - General improvements:
499 - Allow to rewrite the request destination for https-inspected
500 requests behind the client's back. The documentation already sort
501 of claimed that it was supported by not especially mentioning that
502 it didn't work for https-inspected requests.
503 Fixes SF bug #923 reported by withoutname.
504 - Add support for filtering client request bodies by using
505 CLIENT-BODY-FILTER filters which can be enabled with the
506 client-body-filter action.
507 Patch submitted by Maxim Antonov.

509 - Add the new action suppress-tag{} which can be used to prevent
510 a tagger from adding a tag. Patch submitted by Maxim Antonov.
511 Sponsored by: Robert Klemme
512 - Gracefully handle existing website keys without matching certificates.
513 This can happen if Privoxy was previously running with an invalid
514 TLS configuration that didn't allow it to create a certificate.
515 - Recycle debug bit 4 for Tagging-related messages.
516 - Improve the message shown when the client-tags CGI page
517 is requested with no tags configured.
518 - Shorten the 'donate' and 'participate' links used by templates
519 using redirects. Currently the redirects lead to the FAQ entries
520 but in the future we may want to relocate the content and using
521 redirects makes this more convenient.
522 - Log an error when a PCRE-HOST-PATTERN is used with
523 FEATURE_PCRE_HOST_PATTERNS disabled. Don't treat this a
524 fatal error so the regression tests can be used with and
525 without FEATURE_PCRE_HOST_PATTERNS.
526 - The code compiles with older C compilers again.
527 - The chdir() return code is checked to fix a compiler warning.
528 - The packages feed has been removed from the source tarball.
529 It's usually out of date when the source tarball is generated
531 - Fixed harmless compiler warnings from GCC9 with -D_FORTIFY_SOURCE=2.
532 - windows: Remove obsolete '$(DEST)/doc/images' target.
533 - windows: Install the images referenced in the user manual.
534 - Remove obsolete 'gnu_regex.@OBJEXT@' target.
535 - When installing from the GNUMAkefile, don't create an 'images'
536 directory which is no longer used. The images were relocated to
537 the user-manual directory years ago.
538 - Add new FEATURES to the show-status page and resort list.
539 - Remove unused variable in the OpenSSL-specific code.
540 - Update bug tracker URL in cgi_error_unknown().
541 - Saved a couple of memory allocations when sorting client headers.
542 - Improved a couple of error messages.
543 - Saved memory allocations when using OpenSSL and checking if a
545 - The configure script will bail out if OpenSSL and mbedTLS are
546 enabled at the same time.
547 - Log a message right before exiting gracefully.
548 - A couple of structures have been rearranged to require slightly
550 - When https inspection is enabled and the certificate is invalid
551 the error message is now sent with status code 403 instead of 200.
552 - The Slackware rc script template has been renamed to
553 slackware/rc.privoxy.in to silence complaints when building
555 - When building with MbedTLS support, mbedtls_md5_ret() is used
556 instead of mbedtls_md5() which is deprecated and causes a warning
559 - Action file improvements:
560 - Block requests to eu-tlp03.kameleoon.com/.
561 - Unblock metrics.sr.ht/.
562 - Disable fast-redirects for .fsf.org/.

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

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

823 - Use the IP_FREEBIND socket option, if defined. This allows
824 Privoxy to bind to not-yet assigned IP addresses which is
825 useful in failover environments.
826 Patch by Sam Varshavchik.
827 - Allow to use extended host patterns and vanilla host patterns
828 at the same time by prefixing extended host patterns with
829 "PCRE-HOST-PATTERN:". To enable this, configure with
830 --enable-pcre-host-patterns.
831 Sponsored by: Robert Klemme
832 - Added "Cross-origin resource sharing" (CORS) support.
833 This allows to access Privoxy's CGI interface via JavaScript from
834 another domain (white-listed with the new cors-allowed-origin directive).
835 Based on a patch by Nedzad Hrnjica.

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

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

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

1007 *** Version 3.0.28 stable ***
1009 - Bug fixes for regressions in 3.0.27:
1010 - Fixed misplaced parentheses.
1011 Reported by David Binderman.
1012 - Changed two regression tests to depend on config directive
1013 enable-remote-toggle instead of FEATURE_TOGGLE.
1015 *** Version 3.0.27 stable ***
1017 - General improvements:
1018 - Add a receive-buffer-size directive which can be used to
1019 set the size of the previously statically allocated buffer
1020 in handle_established_connection().
1021 Increasing the buffer size increases Privoxy's memory usage but
1022 can lower the number of context switches and thereby reduce the
1023 CPU usage and potentially increase the throughput.
1024 This is mostly relevant for fast network connections and
1025 large downloads that don't require filtering.
1026 Sponsored by: Robert Klemme
1027 - Add a listen-backlog directive which specifies the backlog
1028 value passed to listen().
1029 Sponsored by: Robert Klemme
1030 - Add an enable-accept-filter directive which allows to
1031 toggle accept filter support at run time when compiled
1032 with FEATURE_ACCEPT_FILTER support.
1033 It makes testing more convenient and now that it's
1034 optional we can emit an error message if enabling
1035 the accept filter fails.
1036 Sponsored by: Robert Klemme
1037 - Add a delay-response{} action.
1038 This is useful to tar pit JavaScript requests that
1039 are endlessly retried in case of blocks. It can also
1040 be used to simulate a slow Internet connection.
1041 Sponsored by: Robert Klemme
1042 - Add a 'trusted-cgi-referrer' directive.
1043 It allows to configure another page or site that can be used
1044 to reach sensitive CGI resources.
1045 Sponsored by: Robert Klemme
1046 - Add a --fuzz mode which exposes Privoxy internals to input
1047 from files or stdout.
1048 Mainly tested with American Fuzzy Lop. For details see:
1049 https://www.fabiankeil.de/talks/fuzzing-on-freebsd/
1050 This work was partially funded with donations and done
1051 as part of the Privoxy month in 2015.
1052 - Consistently use the U(ngreedy) flag in the 'img-reorder' filter.
1053 - listen_loop(): Reuse a single thread attribute object
1054 The object doesn't change and creating a new one for
1055 every thread is a waste of (CPU) time.
1056 Sponsored by: Robert Klemme
1057 - Free csp resources in the thread that belongs to the csp instead
1058 of the main thread which has enough on its plate already.

1060 - Improve 'socket timeout reached' message.
1061 Log the timeout that was triggered and downgrade the
1062 log level to LOG_LEVEL_CONNECT to reduce the log noise
1063 with common debug settings.
1064 The timeout isn't necessary the result of an error and
1065 usually merely indicates that Privoxy's socket timeout
1066 is lower than the relevant timeouts used by client and
1068 Sponsored by: Robert Klemme
1069 - Explicitly taint the server socket in case of CONNECT requests.
1070 This doesn't fix any known problems, but makes
1071 some log messages less confusing.
1072 - Let write_pid_file() terminate if the pid file can't be opened.
1073 Logging the issue at info level is unlikely to help.
1074 - log_error(): Reduce the mutex-protected area by not using a
1075 heap-allocated buffer that is shared between all threads.
1076 This increases performance and reduces the latency with
1077 verbose debug settings and multiple concurrent connections.
1078 Sponsored by: Robert Klemme
1079 - Let zalloc() use calloc() if it's available.
1080 In some situations using calloc() can be faster than
1081 malloc() + memset() and it should never be slower.
1082 In the real world the impact of this change is not
1083 expected to be noticeable.
1084 Sponsored by: Robert Klemme
1085 - Never use select() when poll() is available.
1086 On most platforms select() is limited by FD_SETSIZE while
1087 poll() is not. This was a scaling issue for multi-user setups.
1088 Using poll() has no downside other than the usual risk
1089 that code modifications may introduce new bugs that have
1090 yet to be found and fixed.
1091 At least in theory this commit could also reduce the latency
1092 when there are lots of connections and select() would use
1093 "bit fields in arrays of integers" to store file descriptors.
1094 Another side effect is that Privoxy no longer has to stop
1095 monitoring the client sockets when pipelined requests are
1096 waiting but can't be read yet.
1097 This code keeps the select()-based code behind ifdefs for
1098 now but hopefully it can be removed soonish to make the

1101 - Add a 'reproducible-tarball-dist' target.
1102 It's currently separate from the "tarball-dist" target
1103 because it requires a tar implementation with mtree spec
1105 It's far from being perfect and does not enforce a
1106 reproducible mode, but it's better than nothing.
1107 - Use arc4random() if it's available.
1108 While Privoxy doesn't need high quality pseudo-random numbers
1109 there's no reason not to use them when we can and this silences
1110 a warning emitted by code checkers that can't tell whether or not
1111 the quality matters.
1112 - Show the FEATURE_EXTERNAL_FILTERS status on the status page.
1113 Better late than never. Previously a couple of tests weren't
1114 executed as Privoxy-Regression-Test couldn't detect that the
1115 FEATURE_EXTERNAL_FILTERS dependency was satisfied.
1116 - Ditch FEATURE_IMAGE_DETECT_MSIE.
1117 It's an obsolete workaround we inherited from Junkbuster
1118 and was already disabled by default.
1119 Users that feel the urge to work around issues with
1120 image requests coming from an Internet Explorer version
1121 from more than 15 years ago can still do this using tags.
1122 - Consistently use strdup_or_die() instead of strdup() in
1123 cases where allocation failures aren't expected.
1124 Using strdup_or_die() allows to remove a couple of explicit
1125 error checks which slightly reduces the size of the binary.
1126 - Insert a refresh tag into the /client-tags CGI page when
1127 serving it while a client-specific tag is temporarily enabled.
1128 This makes it less likely that the user ends up
1129 looking at tag state that is out of date.
1130 - Use absolute URLs in the client-tag forms.
1131 It's more consistent with the rest of the CGI page
1132 URLs and makes it more convenient to copy the forms
1134 - cgi_error_disabled(): Use status code 403 and an appropriate response line
1135 - Use a dedicated CGI handler to deal with tag-toggle requests
1136 As a result the /client-tags page is now safe to reach without
1137 trusted Referer header which makes bookmarking or linking to
1139 Finally, refreshing the /client-tags page to show the
1140 current state can no longer unintentionally repeat the
1141 previous toggle request.
1142 - Don't add a "Connection" header for CONNECT requests.
1143 Explicitly sending "Connection: close" is not necessary and
1144 apparently it causes problems with some forwarding proxies
1145 that will close the connection prematurely.
1146 Reported by Marc Thomas.
1147 - Fix compiler warnings.
1150 - rfc2553_connect_to(): Properly detect and log when poll()
1151 reached the time out. Previously this was logged as:
1152 Could not connect to [...]: No error: 0.
1153 which isn't very helpful.
1154 Sponsored by: Robert Klemme
1155 - add_tag_for_client(): Set time_to_live properly.
1156 Previously the time_to_live was always set for the first tag.
1157 Attempts to temporarily enable a tag would result in enabling
1158 it permanently unless no tag was enabled already.
1159 - Revert r1.165 which didn't perform as advertised.
1160 While the idea was to use "https:// when creating links
1161 for the user manual on the website", the actual effect
1162 was to use "https://" when Privoxy was supposed to serve
1163 the user manual itself.
1164 Reported by Yossi Zahn on Privoxy-devel@.
1165 - socks5_connect(): Fail in case of unsupported address types.
1166 Previously they would not be detected right away and
1167 Privoxy would fail later on with an error message that
1168 didn't make it obvious that the problem was socks-related.
1169 So far, no such problems have actually been reported.
1170 - socks5_connect(): Properly deal with socks replies that
1171 contain IPv6 addresses.
1172 Previously parts of the reply were left unread and
1173 later on treated as invalid HTTP response data.
1174 Fixes #904 reported by Danny Goossen who also provided
1175 the initial version of this patch.
1177 - Action file improvements:
1178 - Unblock 'msdn.microsoft.com/'.
1179 It (presumably) isn't used to serve the kind of ads Privoxy should
1180 block by default but happens to serve lots of pages with URLs that
1181 are likely to result in false positives.
1182 Reported by bugreporter1694 in AF#939.
1183 - Disable gif deanimation for requests tagged with CSS-REQUEST.
1184 The action will ignore content that isn't considered text
1185 anyway and explicitly disabling it makes this more obvious
1186 if "action" debugging (debug 65536) is enabled while
1187 "gif deanimation" debugging (debug 256) isn't.
1188 - Explicitly disable HTML filters for requests with CSS-REQUEST tag.
1189 The filters are unlikely to break CSS files but executing
1190 them without (intentionally) getting any hits is a waste of
1191 cpu time and makes the log more noisy when running with
1193 - Unblock 'adventofcode.com/'.

1201 - Privoxy-Log-Parser:
1202 - Don't gather host and resource statistics if they aren't requested.
1203 While the performance impact seems negligible this significantly
1204 reduces the memory usage if there are lots of requests.

1212 While privoxy-log-parser was supposed to detect this already,

1214 somewhat confusing anyway.

1219 - Refer to the git sources instead of CVS.
1220 - Use GNU/Linux when referring to the OS instead of the kernel.
1221 - Add FAQ entry for what to do if editing the config file is access denied.
1222 - Add brief HTTP/2 FAQ.
1223 - Add a small fuzzing section to the developer documentation.
1224 - Add a client-header-tagger{client-ip-address} example.
1225 - Stop suggesting that Privoxy is an anonymizing proxy.
1226 The term could lead to Privoxy users overestimating
1227 what it can do on its own (without Tor).
1228 - Make it more obvious that SPI accepts Paypal, too.
1229 Currently most donations are made through the Paypal account
1230 managed by Zwiebelfreunde e.V. and a more even distribution
1232 - Suggest to log applying actions as well when reproducing problems.
1233 - Explicitly mention that Privoxy binaries are built by individuals
1234 on their own systems. Buyer beware!
1235 - Mention the release feed on the homepage.
1236 - Remove a mysterious comment with a GNU FDL link as it isn't
1237 useful and could confuse license scanners.
1238 In May 2002 it was briefly claimed that "this document" was covered
1239 by the GNU FDL. The commit message (r1.5) doesn't explain the motivation
1240 or whether all copyright holders were actually asked and agreed to the
1241 declared license change.
1242 It's thus hard to tell whether or not the license change was legit,
1243 but luckily two days later the "doc license" was "put" "back to GPL"
1245 At the same time the offending comment with a link to the FDL
1246 (not the GPL) was added for no obvious reason.
1247 Now it's gone again.
1250 - Bump for-privoxy-version to 3.0.27 as we now rely on untrusted
1251 CGI request being rejected with status code 403 (instead of 200).
1252 - Update test for /send-stylesheet and add another one
1255 - Consistently use https:// when linking to the Privoxy website.
1256 - Remove SourceForge references in Copyright header.
1257 - Remove a couple of SourceForge references in a comment.
1258 While at it, fix the grammar.
1259 - Move the site-specific documentation block before the generic one.
1260 While most Privoxy installations don't have a site-specific
1261 documentation block, in cases were it exists it's likely to
1262 be more relevant than the generic one.
1263 Showing it first makes it less likely that users stop reading
1264 before they reach it, especially on pages that don't fit on
1267 - Build system improvements:
1268 - Prefer openjade to jade. On some systems Jade produces
1269 HTML with unescaped ampersands in URLs.
1270 - Prefer OpenSP to SP to be consistent.
1271 - Have Docbook generated HTML files be straight ASCII.
1272 Dealing with a mixture of ISO-8859 and UTF-8 files is problematic.
1273 - Echo the filename to stderr for 'make dok-tidy'.
1274 Make it a bit easier to find errors in docbook generated HTML.
1275 - Warn when still using select().
1276 - Warn when compiling without calloc().
1277 - Make it more obvious that the --with-fdsetsize configure switch
1278 is pointless if poll() is available.
1279 - Remove support for AmigaOS.
1280 - Update windows build system to use supported software.
1281 The cygwin gcc -mno-cygwin option is no longer supported, so
1282 convert the windows build system to use the cygwin cross-compiler
1283 to build "native" code.
1284 - Add --enable-static-linking option for configure
1285 does the same thing as LDFLAGS=-static; ./configure
1286 but nicer than mixing evars and configure options.
1288 *** Version 3.0.26 stable ***
1291 - Fixed crashes with "listen-addr :8118" (SF Bug #902).
1292 The regression was introduced in 3.0.25 beta and reported
1293 by Marvin Renich in Debian bug #834941.
1295 - General improvements:
1296 - Log when privoxy is toggled on or off via cgi interface.
1297 - Highlight the "Info: Now toggled " on/off log message
1298 in the Windows log viewer.
1299 - Highlight the loading actions/filter file log message
1300 in the Windows log viewer.
1301 - Mention client-specific tags on the toggle page as a
1302 potentionally more appropriate alternative.
1304 - Documentation improvements:
1305 - Update download section on the homepage.
1306 The downloads are available from the website now.
1308 - Remove obsolete reference to mailing lists hosted at SourceForge.
1309 - Update the "Before the Release" section of the developer manual.
1311 - Infrastructure improvements:
1312 - Add perl script to generate an RSS feed for the packages
1313 Submitted by "Unknown".
1315 - Build system improvements:
1316 - strptime.h: fix a compiler warning about ambiguous else.
1317 - configure.in: Check for Docbook goo on the BSDs as well.
1318 - GNUMakefile.in: Let the dok-user target remove temporary files.
1320 *** Version 3.0.25 beta ***
1323 - Always use the current toggle state for new requests.
1324 Previously new requests on reused connections inherited
1325 the toggle state from the previous request even though
1326 the toggle state could have changed.
1327 Reported by Robert Klemme.
1328 - Fixed two buffer-overflows in the (deprecated) static
1329 pcre code. These bugs are not considered security issues
1330 as the input is trusted.
1331 Found with afl-fuzz and ASAN.
1333 - General improvements:
1334 - Added support for client-specific tags which allow Privoxy
1335 admins to pre-define tags that are set for all requests from
1336 clients that previously opted in through the CGI interface.
1337 They are useful in multi-user setups where admins may
1338 want to allow users to disable certain actions and filters
1339 for themselves without affecting others.
1340 In single-user setups they are useful to allow more fine-grained
1341 toggling. For example to disable request blocking while still
1342 crunching cookies, or to disable experimental filters only.
1343 This is an experimental feature, the syntax and behaviour may
1344 change in future versions.

1347 which contains the address the request came in on.
1348 For external filters the variable is called $PRIVOXY_LISTEN_ADDRESS.

1355 and after 2038 are expected to be handled properly.
1356 This is mainly useful for Privoxy-Regression-Test but could
1357 also come handy when dealing with time-related support requests.

1365 - Action file improvements:
1366 - Filtering is disabled for Range requests to let download resumption
1367 and Windows updates work with the default configuration.
1368 - Unblock ".ardmediathek.de/".

1375 As the archives have not been migrated, continue to
1376 mention the archives at SF in the contacting section
1378 - Note that the templates should be adjusted if Privoxy is
1379 running as intercepting proxy without getting all requests.
1380 - A bunch of links were converted to https://.
1381 - Rephrase onion service paragraph to make it more obvious
1382 that Tor is involved and that the whole website (and not
1383 just the homepage) is available as onion service.
1384 - Streamline the "More information" section on the homepage further
1385 by additionally ditching the link to the 'See also' section
1386 of the user manual. The section contains mostly links that are
1387 directly reachable from the homepage already and the rest is
1388 not significant enough to get a link from the homepage.
1389 - Change the add-header{} example to set the DNT header
1390 and use a complete section to make copy and pasting
1392 Add a comment to make it obvious that adding the
1393 header is not recommended for obvious reasons.
1394 Using the DNT header as example was suggested by
1396 - Streamline the support-and-service template
1397 Instead of linking to the various support trackers
1398 (whose URLs hopefully change soon), link to the

1400 chances that users actually read it.
1401 - Add a FAQ entry for tainted sockets.
1402 - More sections in the documentation have stable URLs now.
1403 - FAQ: Explain why 'ping config.privoxy.org' is not expected
1404 to reach a local Privoxy installation.
1405 - Note that donations done through Zwiebelfreunde e.V. currently
1406 can't be checked automatically.
1407 - Updated section regarding starting Privoxy under OS X.
1408 - Use dedicated start instructions for FreeBSD and ElectroBSD.
1409 - Removed release instructions for AIX. They haven't been working
1410 for years and unsurprisingly nobody seems to care.
1411 - Removed obsolete reference to the solaris-dist target.
1412 - Updated the release instructions for FreeBSD.
1413 - Removed unfinished release instructions for Amiga OS and HP-UX 11.
1414 - Added a pointer to the Cygwin Time Machine for getting the last release of
1415 Cygwin version 1.5 to use for building Privoxy on Windows.
1416 - Various typos have been fixed.
1418 - Infrastructure improvements:
1419 - The website is no longer hosted at SourceForge and
1420 can be reached through https now.
1421 - The mailing lists at SourceForge have been deprecated,
1422 you can subscribe to the new ones at: https://lists.privoxy.org/
1423 - Migrating the remaining services from SourceForge is
1424 work in progress (TODO list item #53).
1426 - Build system improvements:

1428 with the intent to change the maximum number of client
1429 connections Privoxy can handle. Only works with some libcs.

1434 - Include tools in the generic distribution.
1435 - Let the gen-dist target work in cwds other than current.
1436 - Sort find output that is used for distribution tarballs
1437 to get reproducible results.
1438 - Don't add '-src' to the name of the tar ball generated by the
1439 gen-dist target. The package isn't a source distribution but a
1441 While at it, use a variable for the name to reduce the chances
1442 that the various references get out of sync and fix the gen-upload
1443 target which was looking in the wrong directory.

1453 change the default level by a given value.
1454 This directive affects all tests located after it until the end
1455 of the file or a another "Default level offset" directive is reached.
1456 The purpose of this directive is to make it more convenient to skip
1457 similar tests in a given file without having to remove or disable
1458 the tests completely.

1481 Fixes #1686 reported by Peter Müller and G4JC.
1482 - Fixed buffer scaling in execute_external_filter() that could lead
1483 to crashes. Submitted by Yang Xia in #892.
1484 - Fixed crashes when executing external filters on platforms like
1485 Mac OS X. Reported by Jonathan McKenzie on ijbswa-users@.
1486 - Properly parse ACL directives with ports when compiled with HAVE_RFC2553.
1487 Previously the port wasn't removed from the host and in case of
1488 'permit-access 127.0.0.1 example.org:80' Privoxy would try (and fail)
1489 to resolve "example.org:80" instead of example.org.
1490 Reported by Pak Chan on ijbswa-users@.
1491 - Check requests more carefully before serving them forcefully
1492 when blocks aren't enforced. Privoxy always adds the force token
1493 at the beginning of the path, but would previously accept it anywhere
1494 in the request line. This could result in requests being served that
1495 should be blocked. For example in case of pages that were loaded with
1496 force and contained JavaScript to create additionally requests that
1497 embed the origin URL (thus inheriting the force prefix).
1498 The bug is not considered a security issue and the fix does not make
1499 it harder for remote sites to intentionally circumvent blocks if
1500 Privoxy isn't configured to enforce them.
1501 Fixes #1695 reported by Korda.
1502 - Normalize the request line in intercepted requests to make rewriting
1503 the destination more convenient. Previously rewrites for intercepted
1504 requests were expected to fail unless $hostport was being used, but
1505 they failed "the wrong way" and would result in an out-of-memory
1506 message (vanilla host patterns) or a crash (extended host patterns).
1507 Reported by "Guybrush Threepwood" in #1694.
1508 - Enable socket lingering for the correct socket.
1509 Previously it was repeatedly enabled for the listen socket
1510 instead of for the accepted socket. The bug was found by
1511 code inspection and did not cause any (reported) issues.
1512 - Detect and reject parameters for parameter-less actions.
1513 Previously they were silently ignored.
1514 - Fixed invalid reads in internal and outdated pcre code.
1515 Found with afl-fuzz and AddressSanitizer.
1516 - Prevent invalid read when loading invalid action files.
1517 Found with afl-fuzz and AddressSanitizer.
1518 - Windows build: Use the correct function to close the event handle.
1519 It's unclear if this bug had a negative impact on Privoxy's behaviour.
1520 Reported by Jarry Xu in #891.
1521 - In case of invalid forward-socks5(t) directives, use the
1522 correct directive name in the error messages. Previously they
1523 referred to forward-socks4t failures.
1524 Reported by Joel Verhagen in #889.
1526 - General improvements:
1527 - Set NO_DELAY flag for the accepting socket. This significantly reduces
1528 the latency if the operating system is not configured to set the flag
1529 by default. Reported by Johan Sintorn in #894.
1530 - Allow to build with mingw x86_64. Submitted by Rustam Abdullaev in #135.
1531 - Introduce the new forwarding type 'forward-webserver'.
1532 Currently it is only supported by the forward-override{} action and
1533 there's no config directive with the same name. The forwarding type
1534 is similar to 'forward', but the request line only contains the path
1535 instead of the complete URL.
1536 - The CGI editor no longer treats 'standard.action' special.
1537 Nowadays the official "standards" are part of default.action
1538 and there's no obvious reason to disallow editing them through
1539 the cgi editor anyway (if the user decided that the lack of
1540 authentication isn't an issue in her environment).
1541 - Improved error messages when rejecting intercepted requests
1542 with unknown destination.
1543 - A couple of log messages now include the number of active threads.
1544 - Removed non-standard Proxy-Agent headers in HTTP snipplets
1545 to make testing more convenient.
1546 - Include the error code for pcre errors Privoxy does not recognize.
1547 - Config directives with numerical arguments are checked more carefully.
1548 - Privoxy's malloc() wrapper has been changed to prevent zero-size
1549 allocations which should only occur as the result of bugs.
1550 - Various cosmetic changes.
1552 - Action file improvements:
1553 - Unblock ".deutschlandradiokultur.de/".
1554 Reported by u302320 in #924.
1555 - Add two fast-redirect exceptions for "yandex.ru".
1556 - Disable filter{banners-by-size} for ".plasmaservice.de/".
1557 - Unblock "klikki.fi/adv/".
1558 - Block requests for "resources.infolinks.com/".
1559 Reported by "Black Rider" on ijbswa-users@.
1560 - Block a bunch of criteo domains.
1561 Reported by Black Rider.
1562 - Block "abs.proxistore.com/abe/".
1563 Reported by Black Rider.
1564 - Disable filter{banners-by-size} for ".black-mosquito.org/".
1565 - Disable fast-redirects for "disqus.com/".
1567 - Documentation improvements:
1568 - FAQ: Explicitly point fingers at ASUS as an example of a
1569 company that has been reported to force malware based on
1570 Privoxy upon its customers.
1571 - Correctly document the action type for a bunch of "multi-value"
1572 actions that were incorrectly documented to be "parameterized".
1573 Reported by Gregory Seidman on ijbswa-users@.
1574 - Fixed the documented type of the forward-override{} action
1575 which is obviously 'parameterized'.
1577 - Website improvements:
1578 - Users who don't trust binaries served by SourceForge
1579 can get them from a mirror. Migrating away from SourceForge
1580 is planned for 2016 (TODO list item #53).
1581 - The website is now available as onion service
1582 (http://jvauzb4sb3bwlsnc.onion/).
1584 *** Version 3.0.23 stable ***
1587 - Fixed a DoS issue in case of client requests with incorrect
1588 chunk-encoded body. When compiled with assertions enabled
1589 (the default) they could previously cause Privoxy to abort().
1590 Reported by Matthew Daley. CVE-2015-1380.
1591 - Fixed multiple segmentation faults and memory leaks in the
1592 pcrs code. This fix also increases the chances that an invalid
1593 pcrs command is rejected as such. Previously some invalid commands
1594 would be loaded without error. Note that Privoxy's pcrs sources
1595 (action and filter files) are considered trustworthy input and
1596 should not be writable by untrusted third-parties. CVE-2015-1381.
1597 - Fixed an 'invalid read' bug which could at least theoretically
1598 cause Privoxy to crash. So far, no crashes have been observed.
1600 - Compiles with --disable-force again. Reported by Kai Raven.
1601 - Client requests with body that can't be delivered no longer
1602 cause pipelined requests behind them to be rejected as invalid.
1603 Reported by Basil Hussain.
1605 - General improvements:
1606 - If a pcrs command is rejected as invalid, Privoxy now logs
1607 the cause of the problem as text. Previously the pcrs error
1609 - The tests are less likely to cause false positives.
1611 - Action file improvements:
1612 - '.sify.com/' is no longer blocked. Apparently it is not actually
1613 a pure tracking site (anymore?). Reported by Andrew on ijbswa-users@.
1614 - Unblock banners on .amnesty.de/ which aren't ads.
1616 - Documentation improvements:
1617 - The 'Would you like to donate?' section now also contains
1619 - The list of supported operating systems has been updated.
1620 - The existence of the SF support and feature trackers has been
1621 deemphasized because they have been broken for months.
1622 Most of the time the mailing lists still work.
1623 - The claim that default.action updates are sometimes released
1624 on their own has been removed. It hasn't happened in years.
1625 - Explicitly mention that Tor's port may deviate from the default
1626 when using a bundle. Requested by Andrew on ijbswa-users@.
1628 *** Version 3.0.22 stable ***
1631 - Fixed a memory leak when rejecting client connections due to
1632 the socket limit being reached (CID 66382). This affected
1633 Privoxy 3.0.21 when compiled with IPv6 support (on most
1634 platforms this is the default). CVE-2015-1030.
1635 - Fixed an immediate-use-after-free bug (CID 66394) and two
1636 additional unconfirmed use-after-free complaints made by
1637 Coverity scan (CID 66391, CID 66376). CVE-2015-1031.
1638 - Actually show the FORCE_PREFIX value on the show-status page.
1639 - Properly deal with Keep-Alive headers with timeout= parameters
1640 If the timeout still can't be parsed, use the configured
1641 timeout instead of preventing the client from keeping the
1642 connection alive. Fixes #3615312/#870 reported by Bernard Guillot.
1643 - Not using any filter files no longer results in warning messages
1644 unless an action file is referencing header taggers or filters.
1645 Reported by Stefan Kurtz in #3614835.
1646 - Fixed a bug that prevented Privoxy from reusing some reusable
1647 connections. Two bit masks with different purpose unintentionally
1648 shared the same bit.
1649 - A couple of additional bugs were discovered by Coverity Scan.
1650 The fixes that are not expected to affect users are not explicitly
1651 mentioned here, for details please have a look at the CVS logs.
1653 - General improvements:
1654 - Introduced negative tag patterns NO-REQUEST-TAG and NO-RESPONSE-TAG.
1655 They apply if no matching tag is found after parsing client or
1657 - Add support for external filters which allow to process the
1658 response body with a script or program written in any language
1659 the platform supports. External filters are enabled with
1660 +external-filter{} after they have been defined in one of the
1661 filter files with a header line starting with "EXTERNAL-FILTER:".
1662 External filter support is experimental, not compiled by default
1663 and known not to work on all platforms.
1664 - Add support for the 'PATCH' method as defined in RFC5789.
1665 - Reject requests with unsupported Expect header values.
1666 Fixes a couple of Co-Advisor tests.
1667 - Normalize the HTTP-version in forwarded requests and responses.
1668 This is an explicit RFC 2616 MUST and RFC 7230 mandates that
1669 intermediaries send their own HTTP-version in forwarded
1671 - Server 'Keep-Alive' headers are no longer forwarded. From a user's
1672 point of view it doesn't really matter, but RFC 2616 (obsolete)
1673 mandates that the header is removed and this fixes a Co-Advisor
1675 - Change declared template file encoding to UTF-8. The templates
1676 already used a subset of UTF-8 anyway and changing the declaration
1677 allows to properly display UTF-8 characters used in the action files.
1678 This change may require existing action files with ISO-8859-1
1679 characters that aren't valid UTF-8 to be converted to UTF-8.
1680 Requested by Sam Chen in #582.
1681 - Do not pass rejected keep-alive timeouts to the server. It might
1682 not have caused any problems (we know of), but doing the right
1683 thing shouldn't hurt either.
1684 - Let log_error() use its own buffer size #define to make changing
1685 the log buffer size slightly less inconvenient.
1686 - Turned single-threaded into a "proper" toggle directive with arguments.
1687 - CGI templates no longer enforce new windows for some links.
1688 - Remove an undocumented workaround ('HOST' header removal) for
1689 an Apple iTunes bug that according to #729900 got fixed in 2003.
1691 - Action file improvements:
1692 - The pattern 'promotions.' is no longer being blocked.
1693 Reported by rakista in #3608540.
1694 - Disable fast-redirects for .microsofttranslator.com/.
1695 - Disable filter{banners-by-size} for .dgb-tagungszentren.de/.
1696 - Add adn.speedtest.net as a site-specific unblocker.
1697 Support request #3612908.
1698 - Disable filter{banners-by-size} for creativecommons.org/.
1699 - Block requests to data.gosquared.com/. Reported by cbug in #3613653.
1700 - Unblock .conrad./newsletter/. Reported by David Bo in #3614238.
1701 - Unblock .bundestag.de/.
1702 - Unblock .rote-hilfe.de/.
1703 - Disable fast-redirects for .facebook.com/plugins/like.php.
1704 - Unblock Stackexchange popup URLs that aren't used to serve ads.
1705 Reported by David Wagner in #3615179.
1706 - Disable fast-redirects for creativecommons.org/.
1707 - Unblock .stopwatchingus.info/.
1708 - Block requests for .adcash.com/script/.
1709 Reported by Tyrexionibus in #3615289.
1710 - Disable HTML filters if the response was tagged as JavaScript.
1711 Filtering JavaScript code with filters intended to deal with HTML
1712 is usually a waste of time and, more importantly, may break stuff.
1713 - Use a custom redirect{} for .washingtonpost.com/wp-apps/imrs\.php\?src=
1714 Previously enabling the 'Advanced' settings (or manually enabling
1715 +fast-redirects{}) prevented some images from being loaded properly.
1716 - Unblock "adina*." Fixes #919 reported by Morton A. Goldberg.
1717 - Block '/.*DigiAd'.
1718 - Unblock 'adele*.'. Reported by Adele Lime in #1663.
1719 - Disable banners-by-size for kggp.de/.
1721 - Filter file improvements & bug fixes:
1722 - Decrease the chances that js-annoyances creates invalid JavaScript.
1723 Submitted by John McGowan on ijbswa-users@.
1724 - Let the msn filter hide 'related' ads again.
1725 - Remove a stray '1' in the 'html-annoyances' filter.
1726 - Prevent img-reorder from messing up img tags with empty src
1727 attributes. Fixes #880 reported by Duncan.
1729 - Documentation improvements:
1730 - Updated the 'Would you like to donate?' section.
1731 - Note that invalid forward-override{} parameter syntax isn't
1732 detected until the parameter is used.
1733 - Add another +redirect{} example: a shortcut for illumos bugs.
1734 - Make it more obvious that many operating systems support log
1735 rotation out of the box.
1736 - Fixed dead links. Reported by Mark Nelson in #3614557.
1737 - Rephrased the 'Why is the configuration so complicated?' answer
1738 to be slightly less condescending. Anonymously suggested in #3615122.
1739 - Be more explicit about accept-intercepted-requests's lack of MITM support.
1740 - Make 'demoronizer' FAQ entries more generic.
1741 - Add an example hostname to the --pre-chroot-nslookup description.
1742 - Add an example for a host pattern that matches an IP address.
1743 - Rename the 'domain pattern' to 'host pattern' as it may
1744 contain IP addresses as well.
1745 - Recommend forward-socks5t when using Tor. It seems to work fine and
1746 modifying the Tor configuration to profit from it hasn't been necessary
1748 - Add another redirect{} example to stress that redirect loops can
1749 and should be avoided.
1750 - The usual spelling and grammar fixes. Parts of them were
1751 reported by Reuben Thomas in #3615276.
1752 - Mention the PCRS option letters T and D in the filter section.
1753 - Clarify that handle-as-empty-doc-returns-ok is still useful
1754 and will not be removed without replacement.
1755 - Note that security issues shouldn't be reported using the bug tracker.
1756 - Clarify what Privoxy does if both +block{} and +redirect{} apply.
1757 - Removed the obsolete bookmarklets section.
1759 - Build system improvements:
1760 - Let --with-group properly deal with secondary groups.
1761 Patch submitted by Anatoly Arzhnikov in #3615187.
1762 - Fix web-actions target.
1763 - Add a web-faq target that only updates the FAQ on the webserver.
1764 - Remove already-commented-out non-portable DOSFILTER alternatives.
1765 - Remove the obsolete targets dok-put and dok-get.
1766 - Add a sf-shell target.
1768 *** Version 3.0.21 stable ***
1771 - On POSIX-like platforms, network sockets with file descriptor
1772 values above FD_SETSIZE are properly rejected. Previously they
1773 could cause memory corruption in configurations that allowed
1774 the limit to be reached.
1775 - Proxy authentication headers are removed unless the new directive
1776 enable-proxy-authentication-forwarding is used. Forwarding the
1777 headers potentially allows malicious sites to trick the user
1778 into providing them with login information.
1779 Reported by Chris John Riley.
1780 - Compiles on OS/2 again now that unistd.h is only included
1781 on platforms that have it.
1783 - General improvements:
1784 - The show-status page shows the FEATURE_STRPTIME_SANITY_CHECKS status.
1785 - A couple of assert()s that could theoretically dereference
1786 NULL pointers in debug builds have been relocated.
1787 - Added an LSB info block to the generic start script.
1788 Based on a patch from Natxo Asenjo.
1789 - The max-client-connections default has been changed to 128
1790 which should be more than enough for most setups.
1792 - Action file improvements:
1793 - Block rover.ebay./ar.*\&adtype= instead of "/.*\&adtype=" which
1794 caused too man false positives.
1795 Reported by u302320 in #360284, additional feedback from Adam Piggott.
1796 - Unblock '.advrider.com/' and '/.*ADVrider'.
1797 Anonymously reported in #3603636.
1798 - Stop blocking '/js/slider\.js'.
1799 Reported by Adam Piggott in #3606635 and _lvm in #2791160.
1801 - Filter file improvements:
1802 - Added an iframes filter.
1804 - Documentation improvements:
1805 - The whole GPLv2 text is included in the user manual now,
1806 so Privoxy can serve it itself and the user can read it
1807 without having to wade through GPLv3 ads first.
1808 - Properly numbered and underlined a couple of section titles
1809 in the config that where previously overlooked due to a flaw
1810 in the conversion script. Reported by Ralf Jungblut.
1811 - Improved the support instruction to hopefully make it harder to
1812 unintentionally provide insufficient information when requesting
1813 support. Previously it wasn't obvious that the information we need
1814 in bug reports is usually also required in support requests.
1815 - Removed documentation about packages that haven't been provided
1818 - Privoxy-Regression-Test:
1819 - Only log the test number when not running in verbose mode
1820 The position of the test is rarely relevant and it previously
1821 wasn't exactly obvious which one of the numbers was useful to
1822 repeat the test with --test-number.
1824 - GNUmakefile improvements:
1825 - Factor generate-config-file out of config-file to make testing
1827 - The clean target now also takes care of patch leftovers.
1829 *** Version 3.0.20 beta ***
1832 - Client sockets are now properly shutdown and drained before being
1833 closed. This fixes page truncation issues with clients that aggressively
1834 pipeline data on platforms that otherwise discard already written data.
1835 The issue mainly affected Opera users and was initially reported
1836 by Kevin in #3464439, szotsaki provided additional information to track
1838 - Fix latency calculation for shared connections (disabled by default).
1839 It was broken since their introduction in 2009. The calculated latency
1840 for most connections would be 0 in which case the timeout detection
1841 failed to account for the real latency.
1842 - Reject URLs with invalid port. Previously they were parsed incorrectly and
1843 characters between the port number and the first slash were silently
1844 dropped as shown by curl test 187.
1845 - The default-server-timeout and socket-timeout directives accept 0 as
1847 - Fix a race condition on Windows that could cause Privoxy to become
1848 unresponsive after toggling it on or off through the taskbar icon.
1849 Reported by Tim H. in #3525694.
1850 - Fix the compilation on Windows when configured without IPv6 support.
1851 - Fix an assertion that could cause debug builds to abort() in case of
1852 socks5 connection failures with "debug 2" enabled.
1853 - Fix an assertion that could cause debug builds to abort() if a filter
1854 contained nul bytes in the replacement text.
1856 - General improvements:
1857 - Significantly improved keep-alive support for both client and server
1859 - New debug log level 65536 which logs all actions that were applied to
1861 - New directive client-header-order to forward client headers in a
1862 different order than the one in which they arrived.
1863 - New directive tolerate-pipelining to allow client-side pipelining.
1864 If enabled (3.0.20 beta enables it by default), Privoxy will keep
1865 pipelined client requests around to deal with them once the current
1866 request has been served.
1867 - New --config-test option to let Privoxy exit after checking whether or not
1868 the configuration seems valid. The limitations noted in TODO #22 and #23
1869 still apply. Based on a patch by Ramkumar Chinchani.
1870 - New limit-cookie-lifetime{} action to let cookies expire before the end
1871 of the session. Suggested by Rick Sykes in #1049575.
1872 - Increase the hard-coded maximum number of actions and filter files from
1873 10 to 30 (each). It doesn't significantly affect Privoxy's memory usage
1874 and recompiling wasn't an option for all Privoxy users that reached the
1876 - Add support for chunk-encoded client request bodies. Previously
1877 chunk-encoded request bodies weren't guaranteed to be forwarded correctly,
1878 so this can also be considered a bug fix although chunk-encoded request
1879 bodies aren't commonly used in the real world.
1880 - Add support for Tor's optimistic-data SOCKS extension, which can reduce the
1881 latency for requests on newly created connections. Currently only the
1882 headers are sent optimistically and only if the client request has already
1883 been read completely which rules out requests with large bodies.
1884 - After preventing the client from pipelining, don't signal keep-alive
1885 intentions. When looking at the response headers alone, it previously
1886 wasn't obvious from the client's perspective that no additional responses
1888 - Stop considering client sockets tainted after receiving a request with body.
1889 It hasn't been necessary for a while now and unnecessarily causes test
1890 failures when using curl's test suite.
1891 - Allow HTTP/1.0 clients to signal interest in keep-alive through the
1892 Proxy-Connection header. While such client are rare in the real world, it
1893 doesn't hurt and couple of curl tests rely on it.
1894 - Only remove duplicated Content-Type headers when filters are enabled.
1895 If they are not it doesn't cause ill effects and the user might not want it.
1896 Downgrade the removal message to LOG_LEVEL_HEADER to clarify that it's not
1897 an error in Privoxy and is unlikely to cause any problems in general.
1898 Anonymously reported in #3599335.
1899 - Set the socket option SO_LINGER for the client socket.
1900 - Move several variable declarations to the beginning of their code block.
1901 It's required when compiling with gcc 2.95 which is still used on some
1902 platforms. Initial patch submitted by Simon South in #3564815.
1903 - Optionally try to sanity-check strptime() results before trusting them.
1904 Broken strptime() implementations have caused problems in the past and
1905 the most recent offender seems to be FreeBSD's libc (standards/173421).
1906 - When filtering is enabled, let Range headers pass if the range starts at
1907 the beginning. This should work around (or at least reduce) the video
1908 playback issues with various Apple clients as reported by Duc in #3426305.
1909 - Do not confuse a client hanging up with a connection time out. If a client
1910 closes its side of the connection without sending a request line, do not
1911 send the CLIENT_CONNECTION_TIMEOUT_RESPONSE, but report the condition
1913 - Allow closing curly braces as part of action values as long as they are
1915 - On Windows, the logfile is now written before showing the GUI error
1916 message which blocks until the user acknowledges it.
1917 Reported by Adriaan in #3593603.
1918 - Remove an unreasonable parameter limit in the CGI interface. The new
1919 parameter limit depends on the memory available and is currently unlikely
1920 to be reachable, due to other limits in both Privoxy and common clients.
1921 Reported by Andrew on ijbswa-users@.
1922 - Decrease the chances of parse failures after requests with unsupported
1923 methods were sent to the CGI interface.
1925 - Action file improvements:
1926 - Remove the comment that indicated that updated default.action versions
1927 are released on their own.
1928 - Block 'optimize.indieclick.com/' and 'optimized-by.rubiconproject.com/'
1929 - Unblock 'adjamblog.wordpress.com/' and 'adjamblog.files.wordpress.com/'.
1930 Reported by Ryan Farmer in #3496116.
1931 - Unblock '/.*Bugtracker'. Reported by pwhk in #3522341.
1932 - Add test URLs for '.freebsd.org' and '.watson.org'.
1933 - Unblock '.urbandictionary.com/popular'.
1934 - Block '.adnxs.com/'.

1972 - Filter file improvements & bug fixes:
1973 - Add a referer tagger.
1974 - Reduce the likelihood that the google filter messes up HTML-generating
1975 JavaScript. Reported by Zeno Kugy in #3520260.
1977 - Documentation improvements:
1978 - Revised all OS X sections due to new packaging module (OSXPackageBuilder).
1979 - Update the list of supported operating systems to clarify that all Windows
1980 versions after 95 are expected to work and note that the platform-specific
1981 code for AmigaOS and QNX currently isn't maintained.
1982 - Update 'Signals' section, the only explicitly handled signals are SIGINT,
1984 - Add Haiku to the list of operating systems on which Privoxy is known to
1986 - Add DragonFly to the list of BSDs on which Privoxy is known to run.
1987 - Removed references to redhat-specific documentation set since it no longer
1989 - Removed references to building PDFs since we no longer do so.
1990 - Multiple listen-address directives are supported since 3.0.18, correct the
1991 documentation to say so.
1992 - Remove bogus section about long and short being preferable to int.
1993 - Corrected some Internet JunkBuster references to Privoxy.
1994 - Removed references to www.junkbusters.com since it is no longer
1995 maintained. Reported by Angelina Matson.
1996 - Various grammar and spelling corrections
1997 - Add a client-header-tagger{} example for disabling filtering for range
1999 - Correct a URL in the "Privoxy with Tor" FAQ.
2000 - Spell 'refresh-tags' correctly. Reported by Don in #3571927.
2001 - Sort manpage options alphabetically.
2002 - Remove an incorrect sentence in the toggle section. The toggle state
2003 doesn't affect whether or not the Windows version uses the tray icon.
2004 Reported by Zeno Kugy in #3596395.
2005 - Add new contributors since 3.0.19.
2007 - Log message improvements:
2008 - When stopping to watch a client socket due to pipelining, additionally log
2010 - Log the client socket and its condition before closing it. This makes it
2011 more obvious that the socket actually gets closed and should help when
2012 diagnosing problems like #3464439.
2013 - In case of SOCKS5 failures, do not explicitly log the server's response.
2014 It hasn't helped so far and the response can already be logged by enabling
2015 "debug 32768" anyway. This reverts v1.81 and the follow-up bug fix v1.84.
2016 - Relocate the connection-accepted message from listen_loop() to serve().
2017 This way it's printed by the thread that is actually serving the
2018 connection which is nice when grepping for thread ids in log files.
2021 - Remove compatibility layer for versions prior to 3.0 since it has been
2022 obsolete for more than 10 years now.
2023 - Remove the ijb_isupper() and ijb_tolower() macros from parsers.c since
2024 they aren't used in this file.
2025 - Removed the 'Functions declared include:' comment sections since they tend
2026 to be incomplete, incorrect and out of date and the benefit seems
2028 - Various comment grammar and comprehensibility improvements.
2029 - Remove a pointless fflush() call in chat(). Flushing all streams pretty
2030 much all the time for no obvious reason is ridiculous.
2031 - Relocate ijb_isupper()'s definition to project.h and get the ijb_tolower()
2032 definition from there, too.
2033 - Relocate ijb_isdigit()'s definition to project.h.
2034 - Rename ijb_foo macros to privoxy_foo.
2035 - Add malloc_or_die() which will allow to simplify code paths where malloc()
2036 failures don't need to be handled gracefully.
2037 - Add strdup_or_die() which will allow to simplify code paths where strdup()
2038 failures don't need to be handled gracefully.
2039 - Replace strdup() calls with strdup_or_die() calls where it's safe and
2040 simplifies the code.
2041 - Fix white-space around parentheses.
2042 - Add missing white-space behind if's and the following parentheses.
2043 - Unwrap a memcpy() call in resolve_hostname_to_ip().
2044 - Declare pcrs_get_delimiter()'s delimiters[] static const.
2045 - Various optimisations to remove dead code and merge inefficient code
2046 structures for improved clarity, performance or code compactness.
2047 - Various data type corrections.
2048 - Change visibility of several code segments when compiling without
2049 FEATURE_CONNECTION_KEEP_ALIVE enabled for clarity.
2050 - In pcrs_get_delimiter(), do not use delimiters outside the ASCII range.
2051 Fixes a clang complaint.
2052 - Fix an error message in get_last_url() nobody is supposed to see.
2053 Reported by Matthew Fischer in #3507301.
2054 - Fix a typo in the no-zlib-support complaint. Patch submitted by Matthew
2055 Fischer in #3507304.
2056 - Shorten ssplit()'s prototype by removing the last two arguments. We always
2057 want to skip empty fields and ignore leading delimiters, so having
2058 parameters for this only complicates the API.
2059 - Use an enum for the type of the action value.
2060 - Rename action_name's member takes_value to value_type as it isn't used as
2062 - Turn family mismatches in match_sockaddr() into fatal errors.
2063 - Let enlist_unique_header() verify that the caller didn't pass a header
2064 containing either \r or \n.
2065 - Change the hashes used in load_config() to unsigned int. That's what
2066 hash_string() actually returns and using a potentially larger type
2068 - Use privoxy_tolower() instead of vanilla tolower() with manual casting of
2070 - Catch ssplit() failures in parse_cgi_parameters().
2072 - Privoxy-Regression-Test:
2073 - Add an 'Overwrite condition' directive to skip any matching tests before
2074 it. As it has a global scope, using it is more convenient than clowning
2075 around with the Ignore directive.
2076 - Log to STDOUT instead of STDERR.
2077 - Include the Privoxy version in the output.
2078 - Various grammar and spelling corrections in documentation and code.
2079 - Additional tests for range requests with filtering enabled.
2080 - Tests with mostly invalid range request.
2081 - Add a couple of hide-if-modified-since{} tests with different date formats.
2082 - Cleaned up the format of the regression-tests.action file to match the
2083 format of default.action.
2084 - Remove the "Copyright" line from print_version(). When using --help, every
2085 line of screen space matters and thus shouldn't be wasted on things the
2086 user doesn't care about.
2088 - Privoxy-Log-Parser:
2089 - Improve the --statistics performance by skipping sanity checks for input
2090 that shouldn't affect the results anyway. Add a --strict-checks option
2091 that enables some of the checks again, just in case anybody cares.
2092 - The distribution of client requests per connection is included in
2093 the --statistic output.
2094 - The --accept-unknown-messages option has been removed and the behavior
2096 - Accept and (mostly) highlight new log messages introduced with
2100 - Bump generated Firefox version to 17.
2102 - GNUmakefile improvements:
2103 - The dok-tidy target no longer taints documents with a tidy-mark
2104 - Change RA_MODE from 0664 to 0644. Suggested by Markus Dittrich in
2106 - Remove tidy's clean flag as it changes the scope of attributes.
2107 Link-specific colors end up being applied to all text. Reported by Adam
2108 Piggott in #3569551.
2109 - Leave it up to the user whether or not smart tags are inserted.
2110 - Let w3m itself do the line wrapping for the config file. It works better
2111 than fmt as it can honour pre tags causing less unintentional line breaks.
2112 - Ditch a pointless '-r' passed to rm to delete files.
2113 - The config-file target now requires less manual intervention and updates
2114 the original config.
2115 - Change WDUMP to generate ASCII. Add WDUMP_UTF8 to allow UTF-8 in the
2116 AUTHORS file so the names are right.
2117 - Stop pretending that lynx and links are supported for the documentation.
2119 - configure improvements:
2120 - On Haiku, do not pass -lpthread to the compiler. Haiku's pthreads
2121 implementation is contained in its system library, libroot, so no
2122 additional library needs to be searched.
2123 Patch submitted by Simon South in #3564815.
2124 - Additional Haiku-specific improvements. Disable checks intended for
2125 multi-user systems as Haiku is presently single-user. Group Haiku-specific
2126 settings in their own section, following the pattern for Solaris, OS/2 and
2127 AmigaOS. Add additional library-related settings to remove the need for
2128 providing configure with custom LDFLAGS.
2129 Submitted by Simon South in #3574538.
2131 *** Version 3.0.19 Stable ***
2134 - Prevent a segmentation fault when de-chunking buffered content.
2135 It could be triggered by malicious web servers if Privoxy was
2136 configured to filter the content and running on a platform
2137 where SIZE_T_MAX isn't larger than UINT_MAX, which probably
2138 includes most 32-bit systems. On those platforms, all Privoxy
2139 versions before 3.0.19 appear to be affected.
2140 To be on the safe side, this bug should be presumed to allow
2141 code execution as proving that it doesn't seems unrealistic.
2142 - Do not expect a response from the SOCKS4/4A server until it
2143 got something to respond to. This regression was introduced
2144 in 3.0.18 and prevented the SOCKS4/4A negotiation from working.
2145 Reported by qqqqqw in #3459781.
2147 - General improvements:
2148 - Fix an off-by-one in an error message about connect failures.
2149 - Use a GNUMakefile variable for the webserver root directory and
2150 update the path. Sourceforge changed it which broke various
2151 web-related targets.
2152 - Update the CODE_STATUS description.
2154 *** Version 3.0.18 Stable ***
2157 - If a generated redirect URL contains characters RFC 3986 doesn't
2158 permit, they are (re)encoded. Not doing this makes Privoxy versions
2159 from 3.0.5 to 3.0.17 susceptible to HTTP response splitting (CWE-113)
2160 attacks if the +fast-redirects{check-decoded-url} action is used.
2161 - Fix a logic bug that could cause Privoxy to reuse a server
2162 socket after it got tainted by a server-header-tagger-induced
2163 block that was triggered before the whole server response had
2164 been read. If keep-alive was enabled and the request following
2165 the blocked one was to the same host and using the same forwarding
2166 settings, Privoxy would send it on the tainted server socket.
2167 While the server would simply treat it as a pipelined request,
2168 Privoxy would later on fail to properly parse the server's
2169 response as it would try to parse the unread data from the
2170 first response as server headers for the second one.
2171 Regression introduced in 3.0.17.
2172 - When implying keep-alive in client_connection(), remember that
2173 the client didn't. Fixes a regression introduced in 3.0.13 that
2174 would cause Privoxy to wait for additional client requests after
2175 receiving a HTTP/1.1 request with "Connection: close" set
2176 and connection sharing enabled.
2177 With clients which terminates the client connection after detecting
2178 that the whole body has been received it doesn't really matter,
2179 but with clients that don't the connection would be kept open until
2181 - Fix a subtle race condition between prepare_csp_for_next_request()
2182 and sweep(). A thread preparing itself for the next client request
2183 could briefly appear to be inactive.
2184 If all other threads were already using more recent files,
2185 the thread could get its files swept away under its feet.
2186 So far this has only been reproduced while stress testing in
2187 valgrind while touching action files in a loop. It's unlikely
2188 to have caused any actual problems in the real world.
2189 - Disable filters if SDCH compression is used unless filtering is forced.
2190 If SDCH was combined with a supported compression algorithm, Privoxy
2191 previously could try to decompress it and ditch the Content-Encoding
2192 header even though the SDCH compression wasn't dealt with.
2193 Reported by zebul666 in #3225863.
2194 - Make a copy of the --user value and only mess with that when splitting
2195 user and group. On some operating systems modifying the value directly
2196 is reflected in the output of ps and friends and can be misleading.
2197 Reported by zepard in #3292710.
2198 - If forwarded-connect-retries is set, only retry if Privoxy is actually
2199 forwarding the request. Previously direct connections would be retried
2201 - Fixed a small memory leak when retrying connections with IPv6
2203 - Remove an incorrect assertion in compile_dynamic_pcrs_job_list()
2204 It could be triggered by a pcrs job with an invalid pcre
2205 pattern (for example one that contains a lone quantifier).
2206 - If the --user argument user[.group] contains a dot, always bail out
2207 if no group has been specified. Previously the intended, but undocumented
2208 (and apparently untested), behaviour was to try interpreting the whole
2209 argument as user name, but the detection was flawed and checked for '0'
2210 instead of '\0', thus merely preventing group names beginning with a zero.
2211 - In html_code_map[], use a numeric character reference instead of '
2212 which wasn't standardized before XHTML 1.0.
2213 - Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION
2214 and shut down through http://config.privoxy.org/die
2215 - In get_actions(), fix the "temporary" backwards compatibility hack
2216 to accept block actions without reason.
2217 It also covered other actions that should be rejected as invalid.
2218 Reported by Billy Crook.
2220 - General improvements:
2221 - Privoxy can (re)compress buffered content before delivering
2222 it to the client. Disabled by default as most users wouldn't
2224 - The +fast-redirects{check-decoded-url} action checks URL
2225 segments separately. If there are other parameters behind
2226 the redirect URL, this makes it unnecessary to cut them off
2227 by additionally using a +redirect{} pcrs command.
2228 Initial patch submitted by Jamie Zawinski in #3429848.
2229 - When loading action sections, verify that the referenced filters
2230 exist. Currently missing filters only result in an error message,
2231 but eventually the severity will be upgraded to fatal.
2232 - Allow to bind to multiple separate addresses.
2233 Patch set submitted by Petr Pisar in #3354485.
2234 - Set socket_error to errno if connecting fails in rfc2553_connect_to().
2235 Previously rejected direct connections could be incorrectly reported
2236 as DNS issues if Privoxy was compiled with IPv6 support.
2237 - Adjust url_code_map[] so spaces are replaced with %20 instead of '+'
2238 While '+' can be used by client's submitting form data, this is not
2239 actually what Privoxy is using the lookups for. This is more of a
2240 cosmetic issue and doesn't fix any known problems.
2241 - When compiled without FEATURE_FAST_REDIRECTS, do not silently
2242 ignore +fast-redirect{} directives
2243 - Added a workaround for GNU libc's strptime() reporting negative
2244 year values when the parsed year is only specified with two digits.
2245 On affected systems cookies with such a date would not be turned
2246 into session cookies by the +session-cookies-only action.
2247 Reported by Vaeinoe in #3403560
2248 - Fixed bind failures with certain GNU libc versions if no non-loopback
2249 IP address has been configured on the system. This is mainly an issue
2250 if the system is using DHCP and Privoxy is started before the network
2251 is completely configured.
2252 Reported by Raphael Marichez in #3349356.
2253 Additional insight from Petr Pisar.
2254 - Privoxy log messages now use the ISO 8601 date format %Y-%m-%d.
2255 It's only slightly longer than the old format, but contains
2256 the full date including the year and allows sorting by date
2257 (when grepping in multiple log files) without hassle.
2258 - In get_last_url(), do not bother trying to decode URLs that do
2259 not contain at least one '%' sign. It reduces the log noise and
2260 a number of unnecessary memory allocations.
2261 - In case of SOCKS5 failures, dump the socks response in the log message.
2262 - Simplify the signal setup in main().
2263 - Streamline socks5_connect() slightly.
2264 - In socks5_connect(), require a complete socks response from the server.
2265 Previously Privoxy didn't care how much data the server response
2266 contained as long as the first two bytes contained the expected
2267 values. While at it, shrink the buffer size so Privoxy can't read
2268 more than a whole socks response.
2269 - In chat(), do not bother to generate a client request in case of
2270 direct CONNECT requests. It will not be used anyway.
2271 - Reduce server_last_modified()'s stack size.
2272 - Shorten get_http_time() by using strftime().
2273 - Constify the known_http_methods pointers in unknown_method().
2274 - Constify the time_formats pointers in parse_header_time().
2275 - Constify the formerly_valid_actions pointers in action_used_to_be_valid().
2276 - Introduce a GNUMakefile MAN_PAGE variable that defaults to privoxy.1.
2277 The Debian package uses section 8 for the man page and this
2278 should simplify the patch.
2279 - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
2280 - In block_url(), ditch the obsolete workaround for ancient Netscape versions
2281 that supposedly couldn't properly deal with status code 403.
2282 - Remove a useless NULL pointer check in load_trustfile().
2283 - Remove two useless NULL pointer checks in load_one_re_filterfile().
2284 - Change url_code_map[] from an array of pointers to an array of arrays
2285 It removes an unnecessary layer of indirection and on 64bit system reduces
2286 the size of the binary a bit.
2287 - Fix various typos. Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
2288 - Add a dok-tidy GNUMakefile target to clean up the messy HTML
2289 generated by the other dok targets.
2290 - GNUisms in the GNUMakefile have been removed.
2291 - Change the HTTP version in static responses to 1.1
2292 - Synced config.sub and config.guess with upstream
2293 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
2294 - Add a dedicated function to parse the values of toggles. Reduces duplicated
2295 code in load_config() and provides better error handling. Invalid or missing
2296 toggle values are now a fatal error instead of being silently ignored.
2297 - Terminate HTML lines in static error messages with \n instead of \r\n.
2298 - Simplify cgi_error_unknown() a bit.
2299 - In LogPutString(), don't bother looking at pszText when not
2300 actually logging anything.
2301 - Change ssplit()'s fourth parameter from int to size_t.
2302 Fixes a clang complaint.
2303 - Add a warning that the statistics currently can't be trusted.
2304 Mention Privoxy-Log-Parser's --statistics option as
2305 an alternative for the time being.
2306 - In rfc2553_connect_to(), start setting cgi->error_message on error.
2307 - Change the expected status code returned for http://p.p/die depending
2308 on whether or not FEATURE_GRACEFUL_TERMINATION is available.
2309 - In cgi_die(), mark the client connection for closing.
2310 If the client will fetch the style sheet through another connection
2311 it gets the main thread out of the accept() state and should thus
2312 trigger the actual shutdown.
2313 - Add a proper CGI message for cgi_die().
2314 - Don't enforce a logical line length limit in read_config_line().
2315 - Slightly refactor server_last_modified() to remove useless gmtime*() calls.
2316 - In get_content_type(), also recognize '.jpeg' as JPEG extension.
2317 - Add '.png' to the list of recognized file extensions in get_content_type().
2318 - In block_url(), consistently use the block reason "Request blocked by Privoxy"
2319 In two places the reason was "Request for blocked URL" which hides the
2320 fact that the request got blocked by Privoxy and isn't necessarily
2321 correct as the block may be due to tags.
2322 - In listen_loop(), reload the configuration files after accepting
2323 a new connection instead of before.
2324 Previously the first connection that arrived after a configuration
2325 change would still be handled with the old configuration.
2326 - In chat()'s receive-data loop, skip a client socket check if
2327 the socket will be written to right away anyway. This can
2328 increase the transfer speed for unfiltered content on fast
2329 network connections.
2330 - The socket timeout is used for SOCKS negotiations as well which
2331 previously couldn't timeout.
2332 - Don't keep the client connection alive if any configuration file
2333 changed since the time the connection came in. This is closer to
2334 Privoxy's behaviour before keep-alive support for client connection
2335 has been added and also less confusing in general.
2336 - Treat all Content-Type header values containing the pattern
2337 'script' as a sign of text. Reported by pribog in #3134970.
2339 - Action file improvements:
2340 - Moved the site-specific block pattern section below the one for the
2341 generic patterns so for requests that are matched in both, the block
2342 reason for the domain is shown which is usually more useful than showing
2343 the one for the generic pattern.
2344 - Remove -prevent-compression from the fragile alias. It's no longer
2345 used anywhere by default and isn't known to break stuff anyway.
2346 - Add a (disabled) section to block various Facebook tracking URLs.
2347 Reported by Dan Stahlke in #3421764.
2348 - Add a (disabled) section to rewrite and redirect click-tracking
2349 URLs used on news.google.com.
2350 Reported by Dan Stahlke in #3421755.
2351 - Unblock linuxcounter.net/.
2352 Reported by Dan Stahlke in #3422612.
2353 - Block 'www91.intel.com/' which is used by Omniture.
2354 Reported by Adam Piggott in #3167370.
2355 - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
2356 Reminded by tceverling in #2790091.
2357 - Add ".ivwbox.de/" to the "Cross-site user tracking" section.
2358 Reported by Nettozahler in #3172525.
2359 - Unblock and fast-redirect ".awin1.com/.*=http://".
2360 Reported by Adam Piggott in #3170921.
2361 - Block "b.collective-media.net/".
2362 - Widen the Debian popcon exception to "qa.debian.org/popcon".
2363 Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
2364 - Block ".gemius.pl/" which only seems to be used for user tracking.
2365 Reported by johnd16 in #3002731. Additional input from Lee and movax.
2366 - Disable banners-by-size filters for '.thinkgeek.com/'.
2367 The filter only seems to catch pictures of the inventory.
2368 - Block requests for 'go.idmnet.bbelements.com/please/showit/'.
2369 Reported by kacperdominik in #3372959.
2370 - Unblock adainitiative.org/.
2371 - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'.
2372 - Add a fast-redirects exception for webcache.googleusercontent.com/.
2373 - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/.
2375 - Filter file improvements:
2376 - Let the yahoo filter hide '.ads'.
2377 - Let the msn filter hide overlay ads for Facebook 'likes' in search
2378 results and elements with the id 's_notf_div'. They only seem to be
2379 used to advertise site 'enhancements'.
2380 - Let the js-events filter additionally disarm setInterval().
2381 Suggested by dg1727 in #3423775.
2383 - Documentation improvements:
2384 - Clarify the effect of compiling Privoxy with zlib support.
2385 Suggested by dg1727 in #3423782.
2386 - Point out that the SourceForge messaging system works like a black
2387 hole and should thus not be used to contact individual developers.
2388 - Mention some of the problems one can experience when not explicitly
2389 configuring an IP addresses as listen address.
2390 - Explicitly mention that hostnames can be used instead of IP addresses
2391 for the listen-address, that only the first address returned will be
2392 used and what happens if the address is invalid.
2393 Requested by Calestyo in #3302213.
2395 - Log message improvements:
2396 - If only the server connection is kept alive, do not pretend to
2397 wait for a new client request.
2398 - Remove a superfluous log message in forget_connection().
2399 - In chat(), properly report missing server responses as such
2400 instead of calling them empty.
2401 - In forwarded_connect(), fix a log message nobody should ever see.
2402 - Fix a log message in socks5_connect(), a failed write operation
2403 was logged as failed read operation.
2404 - Let load_one_actions_file() properly complain about a missing
2405 '{' at the beginning of the file.
2406 Simply stating that a line is invalid isn't particularly helpful.
2407 - Do not claim to listen on a socket until Privoxy actually does.
2408 Patch submitted by Petr Pisar #3354485
2409 - Prevent a duplicated LOG_LEVEL_CLF message when sending out
2410 the "no-server-data" response.
2411 - Also log the client socket when dropping a connection.
2412 - Include the destination host in the 'Request ... marked for
2413 blocking. limit-connect{...} doesn't allow CONNECT ...' message
2414 Patch submitted by Saperski in #3296250.
2415 - Prevent a duplicated log message if none of the resolved IP
2416 addresses were reachable.
2417 - In connect_to(), do not pretend to retry if forwarded-connect-retries
2419 - When a specified user or group can't be found, put the name in
2420 single-quotes when logging it.
2421 - In rfc2553_connect_to(), explain getnameinfo() errors better.
2422 - Remove a useless log message in chat().
2423 - When retrying to connect, also log the maximum number of connection
2425 - Rephrase a log message in compile_dynamic_pcrs_job_list().
2426 Divide the error code and its meaning with a colon. Call the pcrs
2427 job dynamic and not the filter. Filters may contain dynamic and
2428 non-dynamic pcrs jobs at the same time. Only mention the name of
2429 the filter or tagger, but don't claim it's a filter when it could
2431 - In a fatal error message in load_one_actions_file(), cover both
2432 URL and TAG patterns.
2433 - In pcrs_strerror(), properly report unknown positive error code
2434 values as such. Previously they were handled like 0 (no error).
2435 - In compile_dynamic_pcrs_job_list(), also log the actual error code as
2436 pcrs_strerror() doesn't handle all errors reported by pcre.
2437 - Don't bother trying to continue chatting if the client didn't ask for it.
2438 Reduces log noise a bit.
2439 - Make two fatal error message in load_one_actions_file() more descriptive.
2440 - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'.
2441 - In load_file(), log a message if opening a file failed.
2442 The CGI error message alone isn't too helpful.
2443 - In connection_destination_matches(), improve two log messages
2444 to help understand why the destinations don't match.
2445 - Rephrase a log message in serve(). Client request arrival
2446 should be differentiated from closed client connections now.
2447 - In serve(), log if a client connection isn't reused due to a
2448 configuration file change.
2449 - Let mark_server_socket_tainted() always mark the server socket tainted,
2450 just don't talk about it in cases where it has no effect. It doesn't change
2451 Privoxy's behaviour, but makes understanding the log file easier.
2454 - Added a --disable-ipv6-support switch for platforms where support
2455 is detected but doesn't actually work.
2456 - Do not check for the existence of strerror() and memmove() twice
2457 - Remove a useless test for setpgrp(2). Privoxy doesn't need it and
2458 it can cause problems when cross-compiling.
2459 - Rename the --disable-acl-files switch to --disable-acl-support.
2460 Since about 2001, ACL directives are specified in the standard
2462 - Update the URL of the 'Removing outdated PCRE version after the
2463 next stable release' posting. The old URL stopped working after
2464 one of SF's recent site "optimizations". Reported by Han Liu.
2466 - Privoxy-Regression-Test:
2467 - Added --shuffle-tests option to increase the chances of detection race conditions.
2468 - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy.
2469 - Added tests for missing socks4 and socks4a forwarders.
2470 - The --privoxy-address option now works with IPv6 addresses containing brackets, too.
2471 - Perform limited sanity checks for parameters that are supposed to have numerical values.
2472 - Added a --sleep-time option to specify a number of seconds to
2473 sleep between tests, defaults to 0.
2474 - Disable the range-requests tagger for tests that break if it's enabled.
2475 - Log messages use the ISO 8601 date format %Y-%m-%d.
2476 - Fix spelling in two error messages.
2477 - In the --help output, include a list of supported tests and their default levels.
2478 - Adjust the tests to properly deal with FEATURE_TOGGLE being disabled.
2480 - Privoxy-Log-Parser:
2481 - Perform limited sanity checks for command line parameters that
2482 are supposed to have numerical values.
2483 - Implement a --unbreak-lines-only option to try to revert MUA breakage.
2484 - Accept and highlight: Added header: Content-Encoding: deflate
2485 - Accept and highlight: Compressed content from 29258 to 8630 bytes.
2486 - Accept and highlight: Client request arrived in time on socket 21.
2487 - Highlight: Didn't receive data in time: a.fsdn.com:443
2488 - Accept log messages with ISO 8601 time stamps, too.
2491 - Bump generated Firefox version to 8.0.
2492 - Only randomize the release date if the new --randomize-release-date
2493 option is enabled. Firefox versions after 4 use a fixed date string
2496 *** Version 3.0.17 Stable ***
2498 - Fixed last-chunk-detection for responses where the body was small
2499 enough to be read with the headers, causing Privoxy to wait for the
2500 end of the content until the server closed the connection or the
2501 request timed out. Reported by "Karsten" in #3028326.
2502 - Responses with status code 204 weren't properly detected as body-less
2503 like RFC2616 mandates. Like the previous bug, this caused Privoxy to
2504 wait for the end of the content until the server closed the connection
2505 or the request timed out. Fixes #3022042 and #3025553, reported by a
2506 user with no visible name. Most likely also fixes a bunch of other
2507 AJAX-related problem reports that got closed in the past due to
2508 insufficient information and lack of feedback.
2509 - Fixed an ACL bug that made it impossible to build a blacklist.
2510 Usually the ACL directives are used in a whitelist, which worked
2511 as expected, but blacklisting is still useful for public proxies
2512 where one only needs to deny known abusers access.
2513 - Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
2514 network. This should make debugging various parsing issues a lot easier.
2515 - The IPv6 code is enabled by default on Windows versions that support it.
2516 Patch submitted by oCameLo in #2942729.
2517 - In mingw32 versions, the user.filter file is reachable through the
2518 GUI, just like default.filter is. Feature request 3040263.
2519 - Added the configure option --enable-large-file-support to set a few
2520 defines that are required by platforms like GNU/Linux to support files
2521 larger then 2GB. Mainly interesting for users without proper logfile
2523 - Logging with "debug 16" no longer stops at the first nul byte which is
2524 pretty useless. Non-printable characters are replaced with their hex value
2525 so the result can't span multiple lines making parsing them harder then
2527 - Privoxy logs when reading an action, filter or trust file.
2528 - Fixed incorrect regression test markup which caused a test in
2529 3.0.16 to fail while Privoxy itself was working correctly.
2530 While Privoxy accepts hide-referer, too, the action name is actually
2531 hide-referrer which is also the name used one the final results page,
2532 where the test expected the alias.
2534 - CGI interface improvements:
2535 - In finish_http_response(), continue to add the 'Connection: close'
2536 header if the client connection will not be kept alive.
2537 Anonymously pointed out in #2987454.
2538 - Apostrophes in block messages no longer cause parse errors
2539 when the blocked page is viewed with JavaScript enabled.
2540 Reported by dg1727 in #3062296.
2541 - Fix a bunch of anchors that used underscores instead of dashes.
2542 - Allow to keep the client connection alive after crunching the previous request.
2543 Already opened server connections can be kept alive, too.
2544 - In cgi_show_url_info(), don't forget to prefix URLs that only contain
2545 http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott.
2546 - Show the 404 CGI page if cgi_send_user_manual() is called while
2547 local user manual delivery is disabled.
2549 - Action file improvements:
2550 - Enable user.filter by default. Suggested by David White in #3001830.
2551 - Block .sitestat.com/. Reported by johnd16 in #3002725.
2552 - Block .atemda.com/. Reported by johnd16 in #3002723.
2553 - Block js.adlink.net/. Reported by johnd16 in #3002720.
2554 - Block .analytics.yahoo.com/. Reported by johnd16 in #3002713.
2555 - Block sb.scorecardresearch.com, too. Reported by dg1727 in #2992652.
2556 - Fix problems noticed on Yahoo mail and news pages.
2557 - Remove the too broad yahoo section, only keeping the
2558 fast-redirects exception as discussed on ijbswa-devel@.
2559 - Don't block adesklets.sourceforge.net. Reported in #2974204.
2560 - Block chartbeat ping tracking. Reported in #2975895.
2561 - Tag CSS and image requests with cautious and medium settings, too.
2562 - Don't handle view.atdmt.com as image. It's used for click-throughs
2563 so users should be able to "go there anyway".
2564 Reported by Adam Piggott in #2975927.
2565 - Also let the refresh-tags filter remove invalid refresh tags where
2566 the 'url=' part is missing. Anonymously reported in #2986382.
2567 While at it, update the description to mention the fact that only
2568 refresh tags with refresh times above 9 seconds are covered.
2569 - javascript needs to be blocked with +handle-as-empty-document to
2570 work around Firefox bug 492459. So move .js blockers from
2571 +block{Might be a web-bug.} -handle-as-empty-document to
2572 +block{Might be a web-bug.} +handle-as-empty-document.
2573 - ijbswa-Feature Requests-3006719 - Block 160x578 Banners.
2574 - Block another omniture tracking domain.
2575 - Added a range-requests tagger.
2576 - Added two sections to get Flickr's Ajax interface working with
2577 default pre-settings. If you change the configuration to block
2578 cookies by default, you'll need additional exceptions.
2579 Reported by Mathias Homann in #3101419 and by Patrick on ijbswa-users@.
2581 - Documentation improvements:
2582 - Explicitly mention how to match all URLs.
2583 - Consistently recommend socks5 in the Tor FAQ entry and mention
2584 its advantage compared to socks4a. Reported by David in #2960129.
2585 - Slightly improve the explanation of why filtering may appear
2587 - Grammar fixes for the ACL section.
2588 - Fixed a link to the 'intercepting' entry and add another one.
2589 - Rename the 'Other' section to 'Mailing Lists' and reword it
2590 to make it clear that nobody is forced to use the trackers
2591 - Note that 'anonymously' posting on the trackers may not always
2593 - Suggest to enable debug 32768 when suspecting parsing problems.
2595 - Privoxy-Log-Parser improvements:
2596 - Gather statistics for ressources, methods, and HTTP versions
2598 - Also gather statistics for blocked and redirected requests.
2599 - Provide the percentage of keep-alive offers the client accepted.
2600 - Add a --url-statistics-threshold option.
2601 - Add a --host-statistics-threshold option to also gather
2602 statistics about how many request where made per host.
2603 - Fix a bug in handle_loglevel_header() where a 'scan: ' got lost.
2604 - Add a --shorten-thread-ids option to replace the thread id with
2606 - Accept and ignore: Looks like we got the last chunk together
2607 with the server headers. We better stop reading.
2608 - Accept and ignore: Continue hack in da house.
2609 - Accept and higlight: Rejecting connection from 10.0.0.2.
2610 Maximum number of connections reached.
2611 - Accept and highlight: Loading actions file: /usr/local/etc/privoxy/default.action
2612 - Accept and highlight: Loading filter file: /usr/local/etc/privoxy/default.filter
2613 - Accept and highlight: Killed all-caps Host header line: HOST: bestproxydb.com
2614 - Accept and highlight: Reducing expected bytes to 0. Marking
2615 the server socket tainted after throwing 4 bytes away.
2616 - Accept: Merged multiple header lines to: 'X-FORWARDED-PROTO: http X-HOST: 127.0.0.1'
2619 - Remove the next member from the client_state struct. Only the main
2620 thread needs access to all client states so give it its own struct.
2621 - Garbage-collect request_contains_null_bytes().
2622 - Ditch redundant code in unload_configfile().
2623 - Ditch LogGetURLUnderCursor() which doesn't seem to be used anywhere.
2624 - In write_socket(), remove the write-only variable write_len in
2625 an ifdef __OS2__ block. Spotted by cppcheck.
2626 - In connect_to(), don't declare the variable 'flags' on OS/2 where
2627 it isn't used. Spotted by cppcheck.
2628 - Limit the scope of various variables. Spotted by cppcheck.
2629 - In add_to_iob(), turn an interestingly looking for loop into a
2631 - Code cleanup in preparation for external filters.
2632 - In listen_loop(), mention the socket on which we accepted the
2633 connection, not just the source IP address.
2634 - In write_socket(), also log the socket we're writing to.
2635 - In log_error(), assert that escaped characters get logged
2636 completely or not at all.
2637 - In log_error(), assert that ival and sval have reasonable values.
2638 There's no reason not to abort() if they don't.
2639 - Remove an incorrect cgi_error_unknown() call in a
2640 cannot-happen-situation in send_crunch_response().
2641 - Clean up white-space in http_response definition and
2642 move the crunch_reason to the beginning.
2643 - Turn http_response.reason into an enum and rename it
2644 to http_response.crunch_reason.
2645 - Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686 GNU/Linux.
2646 - Fix white-space in a log message in remove_chunked_transfer_coding().
2647 While at it, add a note that the message doesn't seem to
2648 be entirely correct and should be improved later on.
2650 - GNUmakefile improvements:
2651 - Use $(SSH) instead of ssh, so one only needs to specify a username once.
2652 - Removed references to the action feedback thingy that hasn't been
2654 - Consistently use shell.sourceforge.net instead of shell.sf.net so
2655 one doesn't need to check server fingerprints twice.
2656 - Removed GNUisms in the webserver and webactions targets so they
2657 work with standard tar.
2659 *** Version 3.0.16 Stable ***
2661 - Added the config file option handle-as-empty-doc-returns-ok to
2662 work around Firefox bug #492459, which causes Firefox to hang
2663 if JavaScripts are blocked in certain situations. The option is
2664 enabled in the default config file.
2665 - Added the config file option default-server-timeout to control the
2666 assumed default server timeout. Since Privoxy no longer returns
2667 an error message for connection resets on reused client connections,
2668 assuming larger server timeout values appears to actually work
2669 pretty well as long as connections aren't shared.
2670 - Added optional support for FreeBSD's accf_http(9). Use the
2671 configure option --enable-accept-filter to enable it.
2672 - Added fancier Privoxy icons for win32. Contributed by Jeff H.
2673 - In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
2674 - Resolve localhost using whatever address family the operating
2675 system feels like. Previous betas would try to use IPv4 as this
2676 is what most users expect, but this didn't work reliably on
2678 - In the action lists on CGI pages, actions and their parameters are
2679 no longer separated with a space. The action file parser doesn't
2680 actually allow this and will throw an invalid syntax error if actions
2681 and parameters in the action files are separated. Not adding the
2682 spaces means copy and pasting CGI output into the action files works.
2683 - The default keep-alive timeout has been reduced to 5 seconds to work
2684 around hangs in clients that treat the proxy like any other host and
2685 stop allowing any new connections if the "maximum number of
2686 connections per host" is reached.
2687 - Several webbug URLs that look like they are leading to images are now
2688 blocked as image instead of empty documents. Doing the latter causes
2689 WebKit-based clients to show a "missing image" icon which may mess up
2691 - The no-such-domain template is used for DNS resolution
2692 problems with FEATURE_IPV6_SUPPORT enabled. Previously the
2693 connect-failed template was used. Reported by 'zebul666'.
2694 - Accepts quoted expiration dates even though RFC 2109 10.1.2
2695 doesn't seem to allow them. Reported anonymously.
2696 - Don't try to forget connections if connection sharing is disabled.
2697 This wasn't a real problem but caused an unnecessary log message.
2698 - The still undocumented --enable-extended-host-patterns configure
2699 option has a better description.
2700 - Fixed an error message that would claim a write to the server
2701 failed when actually writing to the client failed.
2702 - Log the crunch reason before trying to write to the client.
2703 The log is easier to read that way.
2704 - Several log messages about client connections also mention
2706 - handle-as-empty-document no longer depends on the image blocking
2708 - Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
2709 - uagen, a Firefox User-Agent generator for Privoxy and Mozilla
2710 browsers has been imported and is available in the tarball's
2712 - The scripts in the tools directory treat unknown parameters
2715 *** Version 3.0.15 beta ***
2717 - In case of missing server data, no error message is send to the
2718 client if the request arrived on a reused connection. The client
2719 is then supposed to silently retry the request without bothering
2720 the user. This should significantly reduce the frequency of the
2721 "No server or forwarder data received" error message many users
2723 - More reliable detection of prematurely closed client sockets
2724 with keep-alive enabled.
2725 - FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
2726 FEATURE_CONNECTION_SHARING and now available on
2728 - Improved handling of POST requests on reused connections.
2729 Should fix problems with stalled connections after submitting
2730 form data with some browser configurations.
2731 - Fixed various latency calculation issues.
2732 - Allows the client to pass NTLM authentication requests to a
2733 forwarding proxy. This was already assumed and hinted to work
2734 in 3.0.13 beta but actually didn't. Now it's confirmed to work
2735 with IE, Firefox and Chrome.
2736 Thanks to Francois Botha and Wan-Teh Chang
2737 - Fixed a calculation problem if receiving the server headers
2738 takes more than two reads, that could cause Privoxy to terminate
2739 the connection prematurely. Reported by Oliver.
2740 - Compiles again on platforms such as OpenBSD and systems
2741 using earlier glibc version that don't support AI_ADDRCONFIG.
2742 Anonymously submitted in #2872591.
2743 - A bunch of MS VC project files and Suse and Redhat RPM spec
2744 files have been removed as they were no longer maintained for
2746 - Overly long action lines are properly rejected with a proper
2747 error message. Previously they would be either rejected as
2748 invalid or cause a core dump through abort().
2749 - Already timed-out connections are no longer temporarily remembered.
2750 They weren't reused anyway, but wasted a socket slot.
2751 - len refers to the number of bytes actually read which might
2752 differ from the ones received. Adjust log messages accordingly.
2753 - The optional JavaScript on the CGI page uses encodeURIComponent()
2754 instead of escape() which doesn't encode all characters that matter.
2755 Anonymously reported in #2832722.
2756 - Fix gcc45 warnings in decompress_iob().
2757 - Various log message improvements.
2758 - Privoxy-Regression-Test supports redirect tests.
2759 - Privoxy-Log-Parser can gather some connection statistics.
2761 *** Version 3.0.14 beta ***
2763 - The latency is taken into account when evaluating whether or not to
2764 reuse a connection. This should significantly reduce the number of
2765 connections problems several users reported.
2766 - If the server doesn't specify how long the connection stays alive,
2767 Privoxy errs on the safe side of caution and assumes it's only a second.
2768 - The error pages for connection timeouts or missing server data use a
2769 Last-Modified date in the past. Retry attempts are detected and Privoxy
2770 removes the If-Modified-Since header to prevent the server from responding
2771 with status code 304 in which case the client would reuse the error message.
2772 - Setting keep-alive-timeout to 0 disables keep-alive support. Previously
2773 Privoxy would claim to allow persistence but not reuse the connection.
2774 - Pipelined requests are less likely to be mistaken for the request
2775 body of the previous request. Note that Privoxy still has no real
2776 pipeline support and will either serialize pipelined requests or
2777 drop them in which case the client has to resent them.
2778 - Fixed a crash on some Windows versions when header randomization
2779 is enabled and the date couldn't be parsed.
2780 - Privoxy's keep-alive timeout for the current connection is reduced
2781 to the one specified in the client's Keep-Alive header.
2782 - For HTTP/1.1 requests, Privoxy implies keep-alive support by not
2783 setting any Connection header instead of using 'Connection: keep-alive'.
2784 - If the socket isn't reusable, Privoxy doesn't temporarily waste
2785 a socket slot to remember the connection.
2786 - If keep-alive support is disabled but compiled in, the client's
2787 Keep-Alive header is removed.
2788 - Fixed a bug on mingw32 where downloading large files failed if
2789 keep-alive support was enabled.
2790 - Fixed a bug that (at least theoretically) could cause log
2791 timestamps to be occasionally off by about a second.
2792 - No Proxy-Connection header if added if there already is one.
2793 - The configure script respects the $PATH variable when searching
2796 *** Version 3.0.13 beta ***
2798 - Added IPv6 support. Thanks to Petr Pisar who not only provided
2799 the initial patch but also helped a lot with the integration.
2800 - Added client-side keep-alive support.
2801 - The connection sharing code is only used if the connection-sharing
2803 - The max-client-connections option has been added to restrict
2804 the number of client connections below a value enforced by
2805 the operating system.
2806 - Fixed a regression reintroduced in 3.0.12 that could cause
2807 crashes on mingw32 if header date randomization was enabled.
2808 - Compressed content with extra fields couldn't be decompressed
2809 and would get passed to the client unfiltered. This problem
2810 has only be detected through statical analysis with clang as
2811 nobody seems to be using extra fields anyway.
2812 - If the server resets the Connection after sending only the headers
2813 Privoxy forwards what it got to the client. Previously Privoxy
2814 would deliver an error message instead.
2815 - Error messages in case of connection timeouts use the right
2817 - If spawning a child to handle a request fails, the client
2818 gets an error message and Privoxy continues to listen for
2819 new requests right away.
2820 - The error messages in case of server-connection timeouts or
2821 prematurely closed server connections are now template-based.
2822 - If zlib support isn't compiled in, Privoxy no longer tries to
2823 filter compressed content unless explicitly asked to do so.
2824 - In case of connections that are denied based on ACL directives,
2825 the memory used for the client IP is no longer leaked.
2826 - Fixed another small memory leak if the client request times out
2827 while waiting for client headers other than the request line.
2828 - The client socket is kept open until the server socket has
2829 been marked as unused. This should increase the chances that
2830 the still-open connection will be reused for the client's next
2831 request to the same destination. Note that this only matters
2832 if connection-sharing is enabled.
2833 - A TODO list has been added to the source tarball to give potential
2834 volunteers a better idea of what the current goals are. Donations
2835 are still welcome too: https://www.privoxy.org/faq/general.html#DONATE
2837 *** Version 3.0.12 ***
2839 - The socket-timeout option now also works on platforms whose
2840 select() implementation modifies the timeout structure.
2841 Previously the timeout was triggered even if the connection
2842 didn't stall. Reported by cyberpatrol.
2843 - The Connection: keep-alive code properly deals with files
2844 larger than 2GB. Previously the connection was closed too
2846 - The content length for files above 2GB is logged correctly.
2847 - The user-manual directive on the show-status page links to
2848 the documentation location specified with the directive,
2849 not to the Privoxy website.
2850 - When running in daemon mode, Privoxy doesn't log anything
2851 to the console unless there are errors before the logfile
2853 - The show-status page prints warnings about invalid directives
2854 on the same line as the directives themselves.
2855 - Fixed several justified (but harmless) compiler warnings,
2856 mostly on 64 bit platforms.
2857 - The mingw32 version explicitly requests the default charset
2858 to prevent display problems with some fonts available on more
2859 recent Windows versions. Patch by Burberry.
2860 - The mingw32 version uses the Privoxy icon in the alt-tab
2861 windows. Patch by Burberry.
2862 - The timestamp and the thread id is omitted in the "Fatal error"
2863 message box on mingw32.
2864 - Fixed two related mingw32-only buffer overflows. Triggering
2865 them required control over the configuration file, therefore
2866 this isn't seen as a security issue.
2867 - In verbose mode, or if the new option --show-skipped-tests
2868 is used, Privoxy-Regression-Test logs skipped tests and the
2871 *** Version 3.0.11 ***
2873 - On most platforms, outgoing connections can be kept alive and
2874 reused if the server supports it. Whether or not this improves
2875 things depends on the connection.
2876 - When dropping privileges, membership in supplementary groups
2877 is given up as well. Not doing that can lead to Privoxy running
2878 with more rights than necessary and violates the principle of
2879 least privilege. Users of the --user option are advised to update.
2880 Thanks to Matthias Drochner for reporting the problem,
2881 providing the initial patch and testing the final version.
2882 - Passing invalid users or groups with the --user option
2883 didn't lead to program exit. Regression introduced in 3.0.7.
2884 - The match all section has been moved from default.action
2885 to a new file called match-all.action. As a result the
2886 default.action no longer needs to be touched by the user
2887 and can be safely overwritten by updates.
2888 - The standard.action file has been removed. Its content
2889 is now part of the default.action file.
2890 - In some situations the logged content length was slightly too low.
2891 - Crunched requests are logged with their own log level.
2892 If you used "debug 1" in the past, you'll probably want
2893 to additionally enable "debug 1024", otherwise only passed
2894 requests will be logged. If you only care about crunched
2895 requests, simply replace "debug 1" with "debug 1024".
2896 - The crunch reason has been moved to the beginning of the
2897 crunch message. For HTTP URLs, the protocol is logged as well.
2898 - Log messages are shortened by printing the thread id on its
2899 own (as opposed to putting it inside the string "Privoxy()").
2900 - The config option socket-timeout has been added to control
2901 the time Privoxy waits for data to arrive on a socket.
2902 - Support for remote toggling is controlled by the configure
2903 option --disable-toggle only. In previous versions it also
2904 depended on the action editor and thus configuring with the
2905 --disable-editor option would disable remote toggling support
2907 - Requests with invalid HTTP versions are rejected.
2908 - The template symbol @date@ can be used to include a date(1)-like
2909 time string. Initial patch submitted by Endre Szabo.
2910 - Responses from shoutcast servers are accepted again.
2911 Problem reported and fix suggested by Stefan.
2912 - The hide-forwarded-for-headers action has been replaced with
2913 the change-x-forwarded-for{} action which can also be used to
2914 add X-Forwarded-For headers. The latter functionality already
2915 existed in Privoxy versions prior to 3.0.7 but has been removed
2916 as it was often used unintentionally (by not using the
2917 hide-forwarded-for-headers action).
2918 - A "clear log" view option was added to the mingw32 version
2919 to clear out all of the lines in the Privoxy log window.
2920 Based on a patch submitted by T Ford.
2921 - The mingw32 version uses "critical sections" now, which prevents
2922 log message corruption under load. As a side effect, the
2923 "no thread-safe PRNG" warning could be removed as well.
2924 - The mingw32 version's task bar icon is crossed out and
2925 the color changed to gray if Privoxy is toggled off.
2927 *** Version 3.0.10 ***
2929 - Ordinary configuration file changes no longer cause program
2930 termination on OS/2 if the name of the logfile hasn't been
2931 changed as well. This regression probably crept in with the
2932 logging improvements in 3.0.7. Reported by Maynard.
2933 - The img-reorder filter is less likely to mess up JavaScript code in
2934 img tags. Problem and solution reported by Glenn Washburn in #2014552.
2935 - The source tar ball now includes Privoxy-Log-Parser,
2936 a syntax-highlighter for Privoxy logs. For fancy screenshots see:
2937 http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
2938 Documentation is available through perldoc(1).
2940 *** Version 3.0.9 beta ***
2942 - Added SOCKS5 support (with address resolution done by
2943 the SOCKS5 server). Patch provided by Eric M. Hopper.
2944 - The "blocked" CGI pages include a block reason that was
2945 provided as argument to the last-applying block action.
2946 - If enable-edit-actions is disabled (the default since 3.0.7 beta)
2947 the show-status page hides the edit buttons and explains why.
2948 Previously the user would get the "this feature has been disabled"
2949 message after using the edit button.
2950 - Forbidden CONNECT requests are treated like blocks by default.
2951 The now-pointless treat-forbidden-connects-like-blocks action
2953 - Not enabling limit-connect now allows CONNECT requests to all ports.
2954 In previous versions it would only allow CONNECT requests to port 443.
2955 Use +limit-connect{443} if you think you need the old default behaviour.
2956 - The CGI editor gets turned off after three edit requests with invalid
2957 file modification timestamps. This makes life harder for attackers
2958 who can leverage browser bugs to send fake Referers and intend to
2959 brute-force edit URLs.
2960 - Action settings for multiple patterns in the same section are
2961 shared in memory. As a result these sections take up less space
2962 (and are loaded slightly faster). Problem reported by Franz Schwartau.
2963 - Linear white space in HTTP headers will be normalized to single
2964 spaces before parsing the header's content, headers split across
2965 multiple lines get merged first. This should prevent problems like:
2966 * letting the session-cookies-only action slip
2967 some Cookies through unmodified,
2968 * only suppressing the first line of a header,
2969 thus creating an invalid one, and
2970 * to incorrectly block headers with valid timestamps
2971 that weren't properly recognized.
2972 Headers that could trigger these problems are unlikely to appear
2973 in "normal" web traffic, but could be intentionally generated to
2974 fool some of Privoxy's header parsers.
2975 - Host information is gathered outside the main thread so it's less
2976 likely to delay other incoming connections if the host is misconfigured.
2977 - New config option "hostname" to use a hostname other than
2978 the one returned by the operating system. Useful to speed-up responses
2979 for CGI requests on misconfigured systems. Requested by Max Khon.
2980 - The CGI editor supports the "disable all filters of this type"
2981 directives "-client-header-filter", "-server-header-filter",
2982 "-client-header-tagger" and "-server-header-tagger".
2983 - Fixed false-positives with the link-by-url filter and URLs that
2984 contain the pattern "/jump/".
2985 - The less-download-windows filter no longer messes
2986 "Content-Type: application/x-shockwave-flash" headers up.
2987 - In the show-url-info page's "Final results" section active and
2988 inactive actions are listed separately. Patch provided by Lee.
2989 - The GNUmakefile supports the DESTDIR variable. Patch for
2990 the install target submitted by Radoslaw Zielinski.
2991 - Embedding the content of configuration files in the show-status
2992 page is significantly faster now. For a largish action file (1 MB)
2993 a speedup of about 2450 times has been measured. This is mostly
2994 interesting if you are using large action files or regularly use
2995 Privoxy-Regression-Test while running Privoxy through Valgrind,
2996 for stock configuration files it doesn't really matter.
2997 - If zlib support is unavailable and there are content
2998 filters active but the prevent-compression action is disabled,
2999 the show-url-info page includes a warning that compression
3000 might prevent filtering.
3001 - The show-url-info page provides an OpenSearch Description that
3002 allows to access the page through browser search plugins.
3003 - Custom client-header filters that rewrite the request line
3004 incorrectly no longer cause Privoxy to crash. Reported by din_a4.
3005 - The obsolete kill-popups action has been removed as the
3006 PCRS-based popup filters can do the same and are slightly
3008 - The inspect-jpegs action has been removed.
3009 - The send-wafer and send-vanilla-wafer actions have been removed.
3010 They weren't particular useful and their behaviour could be emulated
3011 with add-header anyway.
3012 - Privoxy-Regression-Test has been significantly improved.
3013 - Most sections in the default.action file contain tests for
3014 Privoxy-Regression-Test to verify that they are working as intended.
3015 - Parts of Privoxy have been refactored to increase maintainability.
3016 - Building with zlib (if available) is done by default.
3018 *** Version 3.0.8 ***
3020 - Fixed a small memory leak when listen-address only specifies the port.
3021 - The source tar balls now include Privoxy-Regression-Test which
3022 (upon other things) can be used to automatically detect some
3023 packaging problems. Packagers are welcome to give it a try.
3024 - Reverted a change in 3.0.7 that caused path patterns to be checked
3025 even if the host pattern match already failed. While this doesn't
3026 noticeable affect the performance, it makes it less likely to run
3027 out of stack space with overly-complex path patterns the user might
3029 - Updated the msn, yahoo and google filters to work as advertised again.
3030 - The warning message shown by the show-status CGI page is easier to
3031 understand. Previously it wasn't clear that the error message
3032 is shown below the invalid directive. (Reported by Lee)
3033 - When regenerating Content-Disposition headers the more common
3034 spelling is used for the name. Previously it was written without caps.
3035 - Less confusing log message if the content type isn't overwritten
3036 because force-text-type wasn't used but the old type doesn't look
3037 like content that would be filtered normally.
3038 - Better log messages if the user tries to execute filters that
3040 - Treat the non-standard Request-Range headers like standard range
3041 headers and suppress them if content filtering is enabled.
3042 - Prevent the log messages for CONNECT requests to unacceptable
3043 ports from printing the limit-connect argument as [null] if
3044 limit-connect hasn't been explicitly enabled.
3045 - Don't disable the mingw32 log window if the logfile directive
3046 isn't used. While it was an intentional change in 3.0.7 at least
3047 one user perceived it as a regression and the same effect can
3048 be achieved by disabling all debug directives.
3049 - Fixed two minor problems related to the win32 build process: a css
3050 file was not being in the installer and the trustfile comment in the
3051 config.txt referenced a nonexisting file
3052 - Minor documentation fixes.
3054 *** Version 3.0.7 beta ***
3056 - Added zlib support to filter content with gzip and deflate
3057 encoding. (Patch provided by Wil Mahan)
3058 - Dedicated filters and actions are used for header filtering.
3059 "filter-client-headers" and "filter-client-headers" are no longer
3060 supported, use server-header-filter{} and client-header-filter{}
3062 - Tags can be used to change actions based on HTTP headers.
3063 - New server-header filter: less-download-windows.
3064 - New client-header taggers: css-requests, image-requests,
3065 client-ip-address, http-method, allow-post, complete-url,
3066 user-agent and privoxy-control.
3067 - New server-header taggers: content-type and privoxy-control.
3068 - The forward-override{} action allows to change the forwarding
3069 settings through the action files, for example based on client
3070 headers like the User-Agent, or the request origin.
3071 - Socks errors are no longer handled by the CGI page for
3072 DNS resolution failures.
3073 - CGI pages use favicons to signal whether they are error
3074 or control pages. This is useful if you rely heavily on
3076 - The show-url-info CGI page shows the forwarding settings.
3077 - "Crunch!" log messages (used when Privoxy answers requests
3078 by itself) now also contain the reason.
3079 - Allow to rewrite the request destination behind the client's back.
3080 - Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
3081 - Fixes possible deadlocks and crashes on OpenBSD.
3082 Patch provided by Ralf Horstmann.
3083 - The CGI action editor allows to edit actionfiles with previously
3084 forbidden characters like dots.
3085 - New trust entries are saved with a comment that contains the
3086 trusted referring URL (Suggested by Daniel Griscom).
3087 - Filter descriptions are HTML encoded automatically.
3088 - New config option "split-large-forms" to work
3089 around a browser bug that caused IE6 and IE7 to ignore
3090 the Submit button on the edit-actions-for-url CGI page.
3091 - New config option "allow-cgi-request-crunching" to allow
3092 requests for Privoxy's CGI pages to be blocked, redirected
3093 or (un)trusted like ordinary requests.
3094 - Empty filter files no longer interrupt the filtering process
3095 prematurely and are correctly listed on the show-status CGI page.
3096 - New config option "accept-intercepted-requests" to combine
3097 Privoxy with any packet filter to build an intercepting proxy
3098 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
3099 - fast-redirects{} catch redirects to https URLs as well.
3100 - redirect{s@foo@bar@} can be used to redirect to a rewritten
3101 version of the original URL.
3102 - Trap unsupported gopher proxy requests.
3103 - Fixed a bug in the User Manual delivery on Windows
3104 (mingw32 only). Images now show up correctly and HTML
3105 pages are no longer padded with garbage data.
3106 - Fixed several minor memory leaks, most of them discovered with Valgrind.
3107 - Only unlink the pidfile if it's actually used.
3108 - Retries after connection problems with forced requests
3109 aren't blocked again.
3110 - On Unix SIGABRT causes a core dump as expected and is no
3111 longer treated as normal shutdown signal.
3112 - The "access denied" CGI page is more descriptive and
3113 allows retries to circumvent the referrer check.
3114 - Updated PCRS to handle unexpected PCRE errors properly.
3115 Fixed crashes that could occur if Privoxy was build
3116 with external PCRE versions newer than Privoxy's internal
3117 one. (Reported by Chung-chieh Shan)
3118 - Fixed crashes with null bytes in PCRS replacement strings
3119 (Patch provided by Felix Gröbert).
3120 - Fixed crashes with header time randomization on mingw32.
3121 - The CGI style sheet is no longer delivered if the referring
3122 page isn't a Privoxy CGI page. This prevents a JavaScript-based
3123 Privoxy detection "attack". Note that detecting Privoxy is
3124 still possible through other ways and Privoxy was never intended
3125 to be invisible anyway.
3126 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
3127 - The show-url-info CGI page displays a warning if Privoxy
3128 is currently toggled off.
3129 - The show-status CGI page suppresses the edit button
3130 for action files if Privoxy has no write access.
3131 - Most CGI error pages react properly to HEAD requests.
3132 - Requests with RFC 3253 HTTP methods (used by Subversion)
3133 are accepted. (Patch provided by Petr Kadlec)
3134 - New config option "templdir" to change the location
3135 of the CGI templates to make sure customized templates
3137 - Better handling of "HTTP/1.1 100 Continue" responses.
3138 - The background of the PNG pattern is transparent.
3139 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
3140 - Fixed crashes and possible action file corruptions
3141 when lines containing hashes are written through the CGI editor.
3142 - Supports dynamic filters which can contain variables.
3143 - Supports tags to change the actions based on client or server headers.
3144 - Incorrect actions are logged before program termination.
3145 - The "actionsfile" syntax in the configuration file is consistent
3146 with the rest of the configuration options and requires the
3147 whole file name. This is an incompatible change, if you use
3148 an old configuration file you might have to append ".action"
3149 to your "actionsfile" directives.
3150 - With the configuration file option "enforce-blocks" the
3151 "go there anyway" mechanism can be disabled without recompiling
3153 - More precise error messages in case of incorrect acl syntax.
3154 - Logs a warning if filtering is enabled but impossible due
3155 to lack of zlib support or use of the prevent-compression action.
3156 - Less noisy handling of Cookie:" and "Connection:" headers.
3157 - Improved error messages in case of connection problems.
3158 - Fix a command-line-parsing bug that was introduced before 3.0.5
3159 beta and caused Privoxy to treat the last argument as configuration
3160 file if no configuration file was specified.
3161 - Treat unknown command line options as fatal errors instead
3162 of silently ignoring them.
3163 - Use string functions with length checks more often.
3164 - Don't log CONNECT requests twice.
3165 - Allow to log the source address for ACL-related connection drops.
3166 - Don't ignore applying filters if the server didn't
3167 specify a Content-Type. Bug reported by Amuro Namie.
3168 - Rejected CONNECT requests are logged with log level info
3169 (enabled by default) and the reason for the block.
3170 - New command line option "--pre-chroot-nslookup hostname" to
3171 intialize the resolver library before chroot'ing. On some systems this
3172 reduces the number of files that must be copied into the chroot tree.
3173 (Patch provided by Stephen Gildea)
3174 - Fix a long-standing memory corruption bug that could cause
3175 Privoxy to overwrite a single byte in memory it didn't explicitly
3176 allocate (but that probably was allocated anyway due to bucket size).
3177 - Send template-based CGI pages as HTTP/1.1 unless the client
3179 - Let the first line in connection established responses
3180 end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
3181 - If no log file has been specified, disable logging instead of logging
3183 - Don't block stderr when in daemon mode.
3184 - Ignore missing zero-chunks when filtering chunk-encoded content.
3185 Earlier Privoxy versions would buffer and then forward the content
3186 unmodified which caused some browsers to simply show empty pages.
3187 - Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
3188 - The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
3189 action isn't being used has been removed.
3190 - Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
3192 - Minor code clean-ups, filter and action file updates.
3193 (Some of them reported by Davide Alberani, Markus Elfring,
3194 Stefan Huehner and Adam Piggott)
3196 *** Version 3.0.6 ***
3198 - New content filters: no-ping, google, msn, yahoo and blogspot.
3199 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
3200 and hide-tor-exit-notation.
3201 - The special header "X-Filter: No" now disables header filtering as well.
3202 - Improved the filters img-reorder, js-annoyances, webbugs,
3203 banners-by-size, banners-by-link and ie-exploits to make them
3204 less likely to break anything.
3205 - Removed outdated URL patterns in default.action and added new ones.
3206 - Added redirection from http://p.p/user-manual to http://p.p/user-manual/
3207 - Changed webinterface default values for hide-user-agent, hide-referrer
3208 and set-image-blocker.
3210 *** Version 3.0.5 beta ***
3212 - Windows version can be installed/started as a service.
3213 - Windows icon stays blue when Privoxy is idle, green when busy.
3214 - Integrated Fabian Keil's extensive patch. See:
3215 http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
3216 following new or significantly improved actions (among many
3217 other improvements):
3219 content-type-overwrite{}
3220 crunch-client-header{string}
3221 crunch-if-none-match
3222 crunch-server-header{string}
3223 fast-redirects{check-decoded-url}
3224 filter-client-headers
3225 filter-server-headers
3227 handle-as-empty-document
3228 hide-accept-language{}
3229 hide-content-disposition{}
3230 hide-if-modified-since
3231 hide-referrer{conditional-block}
3232 overwrite-last-modified{}
3234 treat-forbidden-connects-like-blocks
3236 - Standard-compliant clients are prevented from displaying cached
3237 copies of Privoxy's error messages after the cause of the problem
3239 - Improved DNS error handling.
3240 - Multiple filter files can now be specified in config.
3241 - Added jpeg filtering to defend against MS jpeg vulnerability MS04-028
3242 with the new inspect-jpegs action.
3243 - Removed the "arbitrary" 1000 filter limit - addresses tracker #911950
3244 - Thanks to Jindrich Makovicka for a race condition fix for the log
3245 file. The race condition remains for non-pthread implementations.
3246 Reference patch #1175720. Various other logging enhancements.
3247 - A pile of assorted bug fixes, memory leaks, enhancements, etc.
3248 - Moved Actions file reporting mechanism to SF tracker.
3249 - Two new options for config: enable-remote-http-toggle and
3250 forwarded-connect-retries.
3251 - Trap unsupported FTP requests.
3252 - Let text/xml be filtered.
3253 - Numerous updates to default.action
3254 - Increase the compiled in limit of trusted referrers from 64 to 512
3255 (for trustfile users).
3257 *** Version 3.0.3 ***
3259 - Fixed yet another two memory leaks. Process growth seems stopped now.
3260 - Further tightened security against malicious toggle-off links.
3261 - Excluded text/plain MIME types from filtering. This fixes a

3433 *** Version 2.9.3 pre-Alpha Changes ***
3435 - Amiga support (completely untested by me - I don't have an Amiga)
3436 - "tinygif 3" support (redirects blocked images to a specified URL, so
3437 the browser doesn't have to load and cache many copies of the same
3439 - one case where there were both local and global "referrer" variables
3440 (yuck!) clarified by renaming the local one to "refer".
3441 - Fixed some places where close() was used instead of close_socket().
3442 Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
3443 - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
3444 FORCE_LOAD_PREFIX. Needs fixing properly.
3445 - Most URLs hardcoded into Junkbuster were changed to go through a script
3446 e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
3447 The only other URLs left are the GNU GPL:
3448 http://www.fsf.org/copyleft/gpl.html
3450 http://ijbswa.sourceforge.net/
3451 ... and various URLs which will be intercepted by Junkbuster anyway.
3452 TODO: Still need to do something with the URLs in Junkbuster Corp's
3453 copyright/trademark notice on the bottom of the show-proxy-args page.
3454 - PCRE or GNU Regex is now a #define option.
3457 *** Version 2.9.2 pre-Alpha Changes ***
3459 - Andreas applied the latest version of the FORCE patch.
3462 *** Version 2.9.1 pre-Alpha Changes ***
3464 - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
3465 (BTW: I think FORCE is precise enough, since loading remote
3466 data is the whole purpose of a proxy..)
3467 - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
3468 is more elegant and looks like a hostname in the URL, it doesn't
3469 make clear to the inexperienced user that the proxy is bypassed. It
3470 also has a higher name collision risk.
3471 - Filled in the function header templates for my functions in
3472 parsers.c (again). They obviously got lost in our current
3474 - Cut the credit for the §-referrer-option from the config file,
3475 that Stefan had placed there.
3476 - Improved the re_filterfile
3479 *** Version 2.9.0 pre-Alpha Changes ***
3481 - Now use PCRE, not GNU REGEX. I have not yet had chance to check the
3482 syntax of the block/image/cookie file to ensure that they match what
3483 is expected - however they seem to work.
3484 - Replaced "configure" script with one generated by "autoconf". Also
3485 use a header "config.h" (was ijbconfig.h in my previous release) for
3486 the #defines. "config.h" is now generated with "autoheader" from
3487 "acconfig.h" and "configure.in". (Note that to install you do not
3488 need autoconf or autoheader - just run "./configure".)
3489 To see command-line options, run "./configure --help".
3490 This is my first ever autoconf script, so it has some rough edges
3491 (how PCRE is handled is the roughest).
3492 - Error logging code replaced with new module errlog.c, based on the
3493 one from JunkbusterMT (but with the threading code removed).
3494 - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
3495 apply all of these, since I had already independently done conditional
3496 popup file, conditional image file, and integration of popup code.
3497 - ACL, Jar and trust files conditionally compiled.
3498 - New source file headers.
3499 - Various cosmetic changes. (But I have not consistently ordered the
3500 config files - I think that's worthwhile, but it's 1am and I want to
3502 - RCS tags on .h files.
3503 - RCS tags are const char[] rather than const char *. (Saves 4 bytes
3505 - VC++ project files renamed to vc_junkbuster.*.
3506 - show-proxy-args now shows status of all conditionals, not just REGEX
3507 - Various functions moved around. Most notably all the system-specific
3508 sockets code which was spread between jcc.c, bind.c, and connect.c,
3509 has been moved to "jbsockets.c". The non-system-specific code from
3510 connect.c and socks4.c has been movet to "gateway.c". Also, the
3511 config file loader and the global variables it writes to have been
3512 moved to "loadcfg.c". (Maybe this should go into loaders.c?)
3513 And candidate for the "worst filename ever" award is "miscutil.c",
3514 which contains, well, miscellaneous utility functions like zalloc.
3515 (Suggestions for a better name for this file are welcome!)
3516 - Loaders now use a common function to read a line and skip comments,
3517 and this function also stores the proxy_args.
3518 - Added ./junkbuster --help (Not for Win32 GUI)
3519 - Added ./junkbuster --version (Not for Win32 GUI)
3520 - Win32 resources are now all marked as "U.S. English", rather than
3521 being a mix of "U.S. English", "U.K. English" and "Irish English".
3522 - Version number changes to 2.9.0
