4 *** Version 3.0.33 UNRELEASED ***
7 - handle_established_connection(): Skip the poll()/select() calls
8 if TLS data is pending on the server socket. The TLS library may
9 have already consumed all the data from the server response in
10 which case poll() and select() will not detect that data is
12 Fixes SF bug #926 reported by Wen Yue.
13 - continue_https_chat(): Update csp->server_connection.request_sent
14 after sending the request to make sure the latency is calculated
15 correctly. Previously https connections were not reused after
16 timeout seconds after the first request made on the connection.
17 - free_pattern_spec(): Don't try to free an invalid pointer
18 when unloading an action file with a TAG pattern while
19 Privoxy has been compiled without FEATURE_PCRE_HOST_PATTERNS.
20 Closes: SF patch request #147. Patch by Maxim Antonov.
21 - Establish the TLS connection with the client earlier and decide
22 how to route the request afterwards. This allows to change the
23 forwarding settings based on information from the https-inspected
24 request, for example the path.
25 Adjust build_request_line() to create a CONNECT request line when
26 https-inspecting and forwarding to a HTTP proxy.
27 Fixes SF bug #925 reported by Wen Yue.
28 - load_config(): Add a space that was missing in a log message.
30 - General improvements:
31 - serve(): Close the client socket as well if the server socket
32 for an inspected connection has been closed. Privoxy currently
33 can't establish a new server connection when the client socket
34 is reused and would drop the connection in continue_https_chat()
36 - Don't disable redirect checkers in redirect_url()
37 Disable them in handle_established_connection() instead.
38 Doing it in redirect_url() prevented the +redirect{} and
39 +fast-redirects{} actions from being logged with LOG_LEVEL_ACTIONS.
40 - handle_established_connection(): Slightly improve a comment
41 - handle_established_connection(): Fix a comment
42 - socks5_connect(): Fix indentation.
43 - handle_established_connection(): Improve an error message
44 - create_pattern_spec(): Fix ifdef indentation
47 - Action file improvements:
48 - Disable fast-redirects for .microsoftonline.com/.
49 - Disable fast-redirects for idp.springer.com/.
51 - Privoxy-Regression-Test:
52 - Remove duplicated word in a comment.
55 - contacting: Remove obsolete reference to announce.sgml.
56 - contacting: Request that the browser cache is cleared before
57 producing a log file for submission.
58 - Sponsor FAQ: Note that Privoxy users may follow sponsor links
59 without Referer header set.
60 - newfeatures: Clarify that https inspection also allows to
61 filter https responses.
62 - developer-manual: Mention that announce.txt should be updated
65 *** Version 3.0.32 stable ***
67 - Security/Reliability:
68 - ssplit(): Remove an assertion that could be triggered with a
70 Commit 2256d7b4d67. OVE-20210203-0001. CVE-2021-20272.
71 Reported by: Joshua Rogers (Opera)
72 - cgi_send_banner(): Overrule invalid image types. Prevents a
73 crash with a crafted CGI request if Privoxy is toggled off.
74 Commit e711c505c48. OVE-20210206-0001. CVE-2021-20273.
75 Reported by: Joshua Rogers (Opera)
76 - socks5_connect(): Don't try to send credentials when none are
77 configured. Fixes a crash due to a NULL-pointer dereference
78 when the socks server misbehaves.
79 Commit 85817cc55b9. OVE-20210207-0001. CVE-2021-20274.
80 Reported by: Joshua Rogers (Opera)
81 - chunked_body_is_complete(): Prevent an invalid read of size two.
82 Commit a912ba7bc9c. OVE-20210205-0001. CVE-2021-20275.
83 Reported by: Joshua Rogers (Opera)
84 - Obsolete pcre: Prevent invalid memory accesses with an invalid
85 pattern passed to pcre_compile(). Note that the obsolete pcre code
86 is scheduled to be removed before the 3.0.33 release. There has been
87 a warning since 2008 already.
88 Commit 28512e5b624. OVE-20210222-0001. CVE-2021-20276.
89 Reported by: Joshua Rogers (Opera)
92 - Properly parse the client-tag-lifetime directive. Previously it was
93 not accepted as an obsolete hash value was being used.
94 Reported by: Joshua Rogers (Opera)
95 - decompress_iob(): Prevent reading of uninitialized data.
96 Reported by: Joshua Rogers (Opera).
97 - decompress_iob(): Don't advance cur past eod when looking
98 for the end of the file name and comment.
99 - decompress_iob(): Cast value to unsigned char before shifting.
100 Prevents a left-shift of a negative value which is undefined behaviour.
101 Reported by: Joshua Rogers (Opera)
102 - gif_deanimate(): Confirm that that we have enough data before doing
103 any work. Fixes a crash when fuzzing with an empty document.
104 Reported by: Joshua Rogers (Opera).
105 - buf_copy(): Fail if there's no data to write or nothing to do.
106 Prevents undefined behaviour "applying zero offset to null pointer".
107 Reported by: Joshua Rogers (Opera)
108 - log_error(): Treat LOG_LEVEL_FATAL as fatal even when --stfu is
109 being used while fuzzing.
110 Reported by: Joshua Rogers (Opera).
111 - Respect DESTDIR when considering whether or not to install
112 config files with ".new" extension.
113 - OpenSSL ssl_store_cert(): Fix two error messages.
114 - Fix a couple of format specifiers.
115 - Silence compiler warnings when compiling with NDEBUG.
116 - fuzz_server_header(): Fix compiler warning.
117 - fuzz_client_header(): Fix compiler warning.
118 - cgi_send_user_manual(): Also reject requests if the user-manual
119 directive specifies a https:// URL. Previously Privoxy would try and
120 fail to open a local file.
122 - General improvements:
123 - Log the TLS version and the the cipher when debug 2 is enabled.
124 - ssl_send_certificate_error(): Respect HEAD requests by not sending a body.
125 - ssl_send_certificate_error(): End the body with a single new line.
126 - serve(): Increase the chances that the host is logged when closing
128 - handle_established_connection(): Add parentheses to clarify an expression
129 Suggested by: David Binderman
130 - continue_https_chat(): Explicitly unset CSP_FLAG_CLIENT_CONNECTION_KEEP_ALIVE
131 if process_encrypted_request() fails. This makes it more obvious that the
132 connection will not be reused. Previously serve() relied on
133 CSP_FLAG_SERVER_CONTENT_LENGTH_SET and CSP_FLAG_CHUNKED being unset.
134 Inspired by a patch from Joshua Rogers (Opera).
135 - decompress_iob(): Add periods to a couple of log messages
136 - Terminate the body of the HTTP snipplets with a single new line
138 - configure: Add --with-assertions option and only enable assertions
140 - windows build: Use --with-brotli and --with-mbedtls by default and
141 enable dynamic error checking.
142 - gif_deanimate(): Confirm we've got an image before trying to write it
143 Saves a pointless buf_copy() call.
144 - OpenSSL ssl_store_cert(): Remove a superfluous space before the serial number.
146 - Action file improvements:
147 - Disable fast-redirects for .golem.de/
148 - Unblock requests to adri*.
149 - Block requests for trc*.taboola.com/
150 - Disable fast-redirects for .linkedin.com/
152 - Filter file improvements:
153 - Make the second pcrs job of the img-reorder filter greedy again.
154 The ungreedy version broke the img tags on:
155 https://bulk.fefe.de/scalability/.
157 - Privoxy-Log-Parser:
158 - Highlight a few more messages.
159 - Clarify the --statistics output. The shown "Reused connections"
160 are server connections so name them appropriately.
161 - Bump version to 0.9.3.
163 - Privoxy-Regression-Test:
164 - Add the --check-bad-ssl option to the --help output.
165 - Bump version to 0.7.3.
168 - Add pushing the created tag to the release steps in the developer manual.
169 - Clarify that 'debug 32768' should be used in addition to the other debug
170 directives when reporting problems.
171 - Add a 'Third-party licenses and copyrights' section to the user manual.
173 *** Version 3.0.31 stable ***
175 - Security/Reliability:
176 - Prevent an assertion from getting triggered by a crafted CGI request.
177 Commit 5bba5b89193fa. OVE-20210130-0001. CVE-2021-20217.
178 Reported by: Joshua Rogers (Opera)
179 - Fixed a memory leak when decompression fails "unexpectedly".
180 Commit f431d61740cc0. OVE-20210128-0001. CVE-2021-20216.
183 - Fixed detection of insufficient data for decompression.
184 Previously Privoxy could try to decompress a partly
185 uninitialized buffer.
187 *** Version 3.0.30 stable ***
190 - Check the actual URL for redirects when https inspecting requests.
191 Previously Privoxy would only check the path which resulted in
192 rewrite results being rejected as invalid URLs.
193 Reported by withoutname in #1736.
194 - Let the hide-referrer code tolerate Referer headers with https:// URLs.
195 Previously they would always be treated like a changed host.
196 - Use the https headers if the show-request handler is reached through
197 https://. Previously Privoxy would use the http headers which
198 may be empty on a reused connection.
199 - Make CGI_PREFIX protocol-relative when building with FEATURE_HTTPS_INSPECTION.
200 This unbreaks (at least) https://config.privoxy.org/client-tags whose
201 buttons would previously use a http:// URL resulting in browser warnings.
202 - Support using https-inspection and client-header-order at the same time.
203 Previously Privoxy would crash.
204 Reported by: Kai Raven
205 - Properly reject rewrites from http to https as they currently
206 aren't supported. Previously Privoxy would wait for the client
207 to establish an encrypted connection which obviously would not happen.
208 - When https inspection is enabled and Privoxy has been compiled with
209 FEATURE_GRACEFUL_TERMINATION (not recommended for production builds),
210 the TLS backend resources are free'd later on and only if no active
211 connections are left. Prevents crashes when exiting "gracefully" at the
213 - Let the uninstall target remove the config file even if DESTDIR
214 is set and properly announce the deletion of the configuration files.
216 - General improvements:
217 - Allow to rewrite the request destination for https-inspected
218 requests behind the client's back. The documentation already sort
219 of claimed that it was supported by not especially mentioning that
220 it didn't work for https-inspected requests.
221 Fixes SF bug #923 reported by withoutname.
222 - Add support for filtering client request bodies by using
223 CLIENT-BODY-FILTER filters which can be enabled with the
224 client-body-filter action.
225 Patch submitted by Maxim Antonov.
226 Sponsored by: Robert Klemme
227 - Add the new action suppress-tag{} which can be used to prevent
228 a tagger from adding a tag. Patch submitted by Maxim Antonov.
229 Sponsored by: Robert Klemme
230 - Gracefully handle existing website keys without matching certificates.
231 This can happen if Privoxy was previously running with an invalid
232 TLS configuration that didn't allow it to create a certificate.
233 - Recycle debug bit 4 for Tagging-related messages.
234 - Improve the message shown when the client-tags CGI page
235 is requested with no tags configured.
236 - Shorten the 'donate' and 'participate' links used by templates
237 using redirects. Currently the redirects lead to the FAQ entries
238 but in the future we may want to relocate the content and using
239 redirects makes this more convenient.
240 - Log an error when a PCRE-HOST-PATTERN is used with
241 FEATURE_PCRE_HOST_PATTERNS disabled. Don't treat this a
242 fatal error so the regression tests can be used with and
243 without FEATURE_PCRE_HOST_PATTERNS.
244 - The code compiles with older C compilers again.
245 - The chdir() return code is checked to fix a compiler warning.
246 - The packages feed has been removed from the source tarball.
247 It's usually out of date when the source tarball is generated
249 - Fixed harmless compiler warnings from GCC9 with -D_FORTIFY_SOURCE=2.
250 - windows: Remove obsolete '$(DEST)/doc/images' target.
251 - windows: Install the images referenced in the user manual.
252 - Remove obsolete 'gnu_regex.@OBJEXT@' target.
253 - When installing from the GNUMAkefile, don't create an 'images'
254 directory which is no longer used. The images were relocated to
255 the user-manual directory years ago.
256 - Add new FEATURES to the show-status page and resort list.
257 - Remove unused variable in the OpenSSL-specific code.
258 - Update bug tracker URL in cgi_error_unknown().
259 - Saved a couple of memory allocations when sorting client headers.
260 - Improved a couple of error messages.
261 - Saved memory allocations when using OpenSSL and checking if a
263 - The configure script will bail out if OpenSSL and mbedTLS are
264 enabled at the same time.
265 - Log a message right before exiting gracefully.
266 - A couple of structures have been rearranged to require slightly
268 - When https inspection is enabled and the certificate is invalid
269 the error message is now sent with status code 403 instead of 200.
270 - The Slackware rc script template has been renamed to
271 slackware/rc.privoxy.in to silence complaints when building
273 - When building with MbedTLS support, mbedtls_md5_ret() is used
274 instead of mbedtls_md5() which is deprecated and causes a warning
277 - Action file improvements:
278 - Block requests to eu-tlp03.kameleoon.com/.
279 - Unblock metrics.sr.ht/.
280 - Disable fast-redirects for .fsf.org/.
281 - Disable fast-redirects for .gravater.com/.
282 - Disable fast-redirects for .ksta.de/.
283 - Block requests to tag.crsspxl.com/.
284 - Block requests to analytics.slashdotmedia.com/.
285 - Block requests to ml314.com/.
286 - Block requests to .adroll.com/.
287 - Block requests to fastlane.rubiconproject.com/.
288 - Block requests to api.theadex.com/.
289 - Block requests to ih.adscale.de/.
290 - Block requests to .s400.meetrics.net/.
291 - Block requests for pp.lp4.io/.
292 - Block requests for trc-events.taboola.com/.
294 - Filter file improvements:
295 - A allow-autocompletion filter has been added which changes
296 autocomplete="off" to "on" on input fields to allow autocompletion.
297 Requested by Jamie Zawinski in #370.
298 Filter based on a submission by Aaron Linville.
299 - Added an imdb filter.
300 - Added a sourceforge filter that reduces the amount of ads
301 for proprietary software.
302 - Added a github filter that removes the annoying "Sign-Up"
303 banner and the Cookie disclaimer.
304 - Removed a duplicated pcrs command from the js-annoyances filter.
305 - The crude-parental filter now provides a short reason when blocking,
306 inserts a link to Privoxy's webinterface and adds a new line at
307 the end of the generated page.
309 - Privoxy-Log-Parser:
310 - Highlight a few more messages.
311 - Add a handler for tagging messages.
312 - Properly deal with 'Certificate error' crunches
313 Previously the error description was highlighted as 'host'.
314 - Log truncated LOG_LEVEL_CLF messages more gracefully
315 and note that the statistics will be imprecise.
316 - Fixed perldoc typo.
317 - Bump version to 0.9.2.
319 - Privoxy-Regression-Test:
320 - Use http://127.0.0.1:8118/ as default Privoxy address
321 unless http_proxy is set through the environment.
322 - Add a --privoxy-cgi-prefix option that specifies the prefix
323 to use when building URLs that are supposed to reach Privoxy's
324 CGI interface. If it's not set, http://p.p/ is used, which is
325 supposed to work with the default Privoxy configuration.
326 If Privoxy has been built with FEATURE_HTTPS_INSPECTION enabled,
327 and if https inspection is activated with the +https-inspection
328 action, this option can be used with "https://p.p/" provided the
329 system running Privoxy-Regression-Test has been configured to
330 trust the certificate used by Privoxy.
331 Note that there are currently two tests in the official
332 regression-tests.action file that are expected to fail
333 when using "https://p.p/" as privoxy-cgi-prefix.
334 - Skip the connection-established response in get_status_code()
335 when looking for the status code with a CGI prefix
336 that starts with https://. We care about the status code
337 sent by the impersonated web server.
338 - Use --proxy-header when using a CGI prefix with https://
339 and a "Host:" header.
340 - Allow '|' in tokens and values to allow tag patterns like
341 "TAG:^(application|text)/(x-)?javascript$".
342 - When get_cgi_page_or_else() fails, include the URL of the
343 requested page in the log message.
344 - Added a --check-bad-ssl option that can be used to verify that
345 Privoxy detects certificate problems when accessing the test
346 sites from badssl.com.
347 - Bumped version to 0.7.2
350 - Update example output.
351 - Recommend the use of the https-inspection action in the documentation.
352 - Upgrade a couple of URLs to https://.
353 - Add ElectroBSD to the list of operating systems.
354 - Bumped generated Firefox version to 78 (ESR).
355 - Bumped version to 1.2.2.
357 - User documentation:
358 - Remove reference to 'How to Report Bugs Effectively'.
359 It was only rendered as text without URL in the README anyway
360 and there's no indication that users read it ...
361 - Let the dok-readme target fix the location embedded into the
362 README file. This used to be done by CVS but since the git migration
363 it has to be done through other means.
364 - Remove 'experimental' warning for client-specific-tag-related directives.
365 They seem to work reliably and there is no obvious reason
366 why we would change the syntax in the near future.
367 - Describe how to check if Privoxy has been built with
368 FEATURE_HTTPS_INSPECTION.
369 - Add a link to the trusted-cas-file documentation
370 that explains how the user can create the file herself.
371 - Don't explicitly mention the license for the code coming from
372 'Anonymous Coders' and Junkbusters. It's obviously licensed under
373 the GNU GPL like the rest of Privoxy or we wouldn't be allowed to
375 - Update the +hide-user-agent example with uagen output.
376 - Slightly improve the wording of the ca-key-file documentation.
377 - Explicitly mention Windows 10 as supported so search engines and
378 users looking for it can find it.
379 - Import a bunch of contributors from the ChangeLog.
380 - Remove obsolete doc/gpl.html.
381 - Upgrade a couple of links to https://.
382 - Don't prefer the SourceForge patch tracker over the
383 privoxy-devel mailing list. While at it, link to the
384 SourceForge patch tracker.
385 - Mention http-inspection in the 'my browser warns me about
386 unauthenticated content' FAQ entry.
387 - Simplify the 'Is there is a license or fee?' FAQ entry.
388 - Add another +redirect{} example.
389 - Explicitly mention that interested sponsors should include
390 the link target in their first mail.
391 - Clarify that only Privoxy team members can object to new sponsors
392 and link to the list of current team members.
393 - Note that sponsor URLs may not contain keyword spam.
394 - Garbage collect doc/webserver/images which isn't referenced anymore.
395 - Update the method to reach the proxy settings in Firefox.
396 - Update proxy_setup.jpg description to refer to Firefox.
397 - Regenerate proxy_setup.jpg with a more recent Firefox (78.0).
398 - Regenerate files-in-use.jpg without obsolete standard.action
399 with modern colors and a slightly better quality.
400 - Update URL to the actionsfile tracker.
401 - Update a support request URL.
402 - Rephrase the 'Can Privoxy run as service' FAQ entry and
403 remove an obsolete paragraph.
404 - Let the 'Where can I get updated Actions Files?' entry link to
405 the gitweb version of default.action.master.
406 - Update a link to the default.action file.
407 - Update URLs for trackers and mailing lists.
408 - Replace CVS reference with git.
409 - Mention regression-tests.action in the config file.
410 - Explicitly mention in the config file that access to the
411 CA key should be limited to Privoxy.
412 - List more client-specific-tag examples for inspiration.
413 - Add additional headers to the client-header-order example.
414 - Note that actions aren't updated after rewrites.
415 - Explicitly mention that upgrading from http to https with
416 a client-header filter is not supported
417 - Note that protocol and host have to be added when rewriting
418 the destination host for https-inspected requests.
419 - Explicitly mention that the CA key is used to sign certificates.
420 - Put openssl command in 'command' tags.
421 - The man page has been moved from section 1 to man section 8.
424 - Flesh out the build instructions for Debian.
425 - Remove the packaging instructions for RPM-based systems.
426 They don't work and we don't release RPM packages anymore anyway.
427 - Remove the packaging instructions for Solaris.
428 They don't work and we don't release Solaris packages anymore anyway.
429 - Update the suggested subject for the announce mails.
430 - Update upload instructions.
431 ftp://upload.sourceforge.net is no longer functional.
432 - Remove a couple of package-dependent upload instructions
433 that don't actually work.
434 - Remove 'cd current' that no longer works.
435 - Add regression-tests.action to the list of files that should be installed.
436 - Stop claiming that there are text versions of the manuals.
437 We stopped building them in 2008 (9ed36a3c5e6f12).
438 - Note that the 'webserver' target creates the link needed for the user-manual.
439 - Suggest to use the master branch as reference when creating
440 the ChangeLog so the steps work when the current branch differs
441 from master which is likely as the developer manual
442 suggests to use a local branch for development.
443 - Add the -s flag to the suggested 'git tag' command. We prefer signed tags.
444 - Mention that merges into 'master' should be avoided.
445 - Add git commands that should result in a merge-free history.
446 - Mention Privoxy-Regression-Test.
447 - Add a section id to reduce link churn.
448 - Recommend the dok-tidy target when building docs for the webserver.
449 - Add another plug for the privoxy-devel mailing list.
450 - Let the intro link the copyright section in the user manual instead
451 of giving an incomplete summary of the license status.
452 - Clarify that the webserver target uploads to the SourceForge webserver.
453 - Mark the documentation for the Mac OS X installers as out of date and
454 change the SCM name back to CVS.
455 - Fix the location of the installer modules for Mac OS X.
456 They are not actually available through git (yet).
457 - Don't speak of Privoxy version 3 in the past tense.
458 - Update the list of programs required for the release process.
459 - Update description of the webserver target which uses ssh, not scp.
460 - Remove obsolete reference to config.new.
463 - Add another hide-referrer{conditional-block} test.
464 - Add another hide-referrer{conditional-forge} test.
465 - Fix a hide-referrer{conditional-forge} test
466 that expected an acceptable header to be forged.
467 - Fix a hide-referrer{conditional-block} test
468 that expected an acceptable Referer to be removed.
469 - Explain why the "Set Header = Host: whatever.example.org" test is
470 expected to fail when using a CGI prefix that starts with "https://".
471 - Explain why a connection-sharing test is known to fail
472 when using "https://p.p/" as CGI prefix.
473 - Add a link to Privoxy-Regression-Test to regression-tests.action
474 in case it isn't packaged.
475 - Add regression tests for pcre host patterns.
476 - Fixed a regression test that is executed when
477 FEATURE_GRACEFUL_TERMINATION is enabled.
479 - Privoxy infrastructure:
480 - Import a Privoxy logo for the website.
481 - Update Tor onion service to HiddenServiceVersion 3.
482 - Display the "model" photos in a single row and remove placeholder images.
483 - Regenerate homepage with updated sponsor list.
484 - Use the '/sponsor' redirect for the link to the sponsor page.
485 - Git commit messages are sent to the Privoxy-commits mailing list.

506 - Fixed a memory leak if multiple filters are executed
507 and the last one is skipped due to a pcre error.
508 Commit 5cfb7bc8fe. OVE-20201118-0005. CVE-2021-20212.
509 - Prevent an unlikely dereference of a NULL-pointer that
510 could result in a crash if accept-intercepted-requests
511 was enabled, Privoxy failed to get the request destination
512 from the Host header and a memory allocation failed.

519 CID 305233. OVE-20201118-0008. CVE-2021-20215.
521 - General improvements:
522 - Added experimental https inspection support which allows to filter
523 https traffic. To enable it, install MbedTLS and configure with
524 --with-mbedtls, or install OpenSSL or LibreSSL and configure
526 Afterwards configure the directives in section 7 of the
527 config file and enable the +https-inspection action.
528 Initial MbedTLS-based code contributed by Vaclav Svec,
529 initial OpenSSL support contributed by Maxim Antonov.
530 With help from Nedzad Hrnjica and Ho+ Ho+ Ho+.
531 Integration and improvements sponsored by Robert Klemme.
532 - pcrs: Request JIT compilation if it's supported and
533 the filter isn't dynamic. This can speed up filtering.
534 - Added support for Brotli decompression.

536 - Added FEATURE_EXTENDED_STATISTICS to gather statistics for
537 block reasons and filter executions. To enable it, configure
538 with --enable-extended-statistics and visit
539 http://config.privoxy.org/show-status.

541 - Use the IP_FREEBIND socket option, if defined. This allows
542 Privoxy to bind to not-yet assigned IP addresses which is
543 useful in failover environments.
544 Patch by Sam Varshavchik.
545 - Allow to use extended host patterns and vanilla host patterns
546 at the same time by prefixing extended host patterns with
547 "PCRE-HOST-PATTERN:". To enable this, configure with
548 --enable-pcre-host-patterns.

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

561 - Fixed handling of filters with "split-large-forms 1"
562 when using the CGI editor.
563 Reported by withoutname in #921.
564 - Better detect a mismatch of connection details when
565 figuring out whether or not a connection can be reused.
566 - Don't send a "Connection failure" message instead of the
567 "DNS failure" message.

569 - Let LOG_LEVEL_REQUEST log all requests. Previously unencrypted
570 requests were only logged with LOG_LEVEL_REQUEST when they weren't
571 crunched (in which case they were logged with LOG_LEVEL_CRUNCH).
572 This was documented behaviour, but logging all requests seems more useful.
573 - Fixed locking around localtime() and gmtime().
574 - Removed OS/2 support. We haven't provided OS/2 packages in years,
575 it complicated the code and it depended on a fallback snprintf()
576 implementation which is GPLv2 only.
577 - Remove the fallback snprintf() implementation
578 Now that OS/2 support is gone we no longer need it.
579 - Fixed a bunch of format specifiers log messages.
580 - Added a missing apostrophe in the 'More Privoxy' menu.
581 - Explicitly prevent use of FEATURE_CONNECTION_SHARING
582 without FEATURE_CONNECTION_KEEP_ALIVE. It makes no sense
583 and does not compile anyway.

595 Only the shadow knows what "GPC" is supposed to stand for.
596 - Remove SourceForge references in copyright headers.
597 - Upgrade a bunch of links to the homepage to https://.
598 - Add 'no-brotli-accepted' filter which prevents the
599 use of Brotli compression.
600 - Changed license for pcrs to GPLv2+ after getting the
601 permission from Andreas. This allows to redistribute
602 Privoxy under the GPLv3 which is required when linking
603 to future mbedTLS versions which are expected to be
604 licensed under the Apache 2.0 license only.
605 - Updated a bunch of tests that have to expect status code 403
606 now after r1.168/070e904afa5.
607 - Lowercase the host name in the request line.
608 - Only set SOURCE_DATE_EPOCH if it's not already set so
609 distributions can overwrite it through the environment.
611 - Documentation changes:
612 - Explain that Privoxy has to be distributed under the
613 GPLv3 (or later) when linked with an MbedTLS version
614 that is licensed under the Apache 2.0 license.
615 - Import the GNU GPLv3 and include it the user manual.
616 - Clarify FEATURE_FORCE_LOAD's description. It allows to bypass
617 blocking not filtering and only does it if blocks aren't enforced.

619 - FAQ: Remove Zwiebelfreunde e.V. from the list of fiduciary sponsors
620 As of 2021 they no longer handle donations for foreign organisations
621 due to lack of resources.
622 - FAQ: Remove an obsolete comment with a link to the long-gone PDF manual.
623 - FAQ: Add a link to the TODO list.

625 converted amounts up to get simple numbers.
626 Receiving USD is apparently easier for SPI and SPI is
627 preferred by sponsors as they can send invoices.

680 - Added a --keep-date option to keep the date in highlighted messages.
681 - Highlight new log messages.
682 - Make gather_loglevel_clf_stats() more tolerant. While at it,
683 count all CLF messages as requests, even if the request is invalid.
684 - Only show HTTP version distribution if at least one version has been detected.
685 - Only show crunch statistics if crunches were detected.
686 - Warn if the request counts differ.
687 - Generate statistics if the log only contains LOG_LEVEL_CLF messages
688 so it can be used with vanilla webserver logs.
689 Previously Privoxy-specific "Request:" messages were required.
690 - Align the client-HTTP-version distribution like other distributions
691 - Bump version to 0.9.1
692 - Include status code distribution in the stats.
693 - Let the statistics include the size of the content Privoxy
694 transferred excluding HTTP headers.
695 - Get with the program and expect all requests to be logged with LOG_LEVEL_REQUEST.
696 It's no longer necessary to count both LOG_LEVEL_REQUEST and
697 LOG_LEVEL_CRUNCH messages to get the total number of requests.
698 - Leverage the LOG_LEVEL_CLF message to gather statistics that where
699 previously taken from LOG_LEVEL_HEADER lines. This results in less
700 confusing results if https inspection is enabled in which case there
701 are two LOG_LEVEL_HEADER lines with request lines.

730 - Changed two regression tests to depend on config directive
731 enable-remote-toggle instead of FEATURE_TOGGLE.
733 *** Version 3.0.27 stable ***
735 - General improvements:
736 - Add a receive-buffer-size directive which can be used to
737 set the size of the previously statically allocated buffer
738 in handle_established_connection().
739 Increasing the buffer size increases Privoxy's memory usage but
740 can lower the number of context switches and thereby reduce the
741 CPU usage and potentially increase the throughput.
742 This is mostly relevant for fast network connections and
743 large downloads that don't require filtering.

745 - Add a listen-backlog directive which specifies the backlog
746 value passed to listen().
747 Sponsored by: Robert Klemme
748 - Add an enable-accept-filter directive which allows to
749 toggle accept filter support at run time when compiled
750 with FEATURE_ACCEPT_FILTER support.
751 It makes testing more convenient and now that it's
752 optional we can emit an error message if enabling
753 the accept filter fails.

755 - Add a delay-response{} action.
756 This is useful to tar pit JavaScript requests that
757 are endlessly retried in case of blocks. It can also
758 be used to simulate a slow Internet connection.

762 to reach sensitive CGI resources.

765 from files or stdout.
766 Mainly tested with American Fuzzy Lop. For details see:

768 This work was partially funded with donations and done
769 as part of the Privoxy month in 2015.
770 - Consistently use the U(ngreedy) flag in the 'img-reorder' filter.

772 The object doesn't change and creating a new one for
773 every thread is a waste of (CPU) time.

778 - Improve 'socket timeout reached' message.
779 Log the timeout that was triggered and downgrade the
780 log level to LOG_LEVEL_CONNECT to reduce the log noise
781 with common debug settings.
782 The timeout isn't necessary the result of an error and
783 usually merely indicates that Privoxy's socket timeout
784 is lower than the relevant timeouts used by client and
786 Sponsored by: Robert Klemme
787 - Explicitly taint the server socket in case of CONNECT requests.
788 This doesn't fix any known problems, but makes
789 some log messages less confusing.
790 - Let write_pid_file() terminate if the pid file can't be opened.
791 Logging the issue at info level is unlikely to help.
792 - log_error(): Reduce the mutex-protected area by not using a
793 heap-allocated buffer that is shared between all threads.
794 This increases performance and reduces the latency with
795 verbose debug settings and multiple concurrent connections.
796 Sponsored by: Robert Klemme
797 - Let zalloc() use calloc() if it's available.
798 In some situations using calloc() can be faster than
799 malloc() + memset() and it should never be slower.

801 expected to be noticeable.

803 - Never use select() when poll() is available.
804 On most platforms select() is limited by FD_SETSIZE while
805 poll() is not. This was a scaling issue for multi-user setups.
806 Using poll() has no downside other than the usual risk
807 that code modifications may introduce new bugs that have
808 yet to be found and fixed.
809 At least in theory this commit could also reduce the latency
810 when there are lots of connections and select() would use
811 "bit fields in arrays of integers" to store file descriptors.
812 Another side effect is that Privoxy no longer has to stop
813 monitoring the client sockets when pipelined requests are
814 waiting but can't be read yet.
815 This code keeps the select()-based code behind ifdefs for
816 now but hopefully it can be removed soonish to make the

819 - Add a 'reproducible-tarball-dist' target.
820 It's currently separate from the "tarball-dist" target
821 because it requires a tar implementation with mtree spec
823 It's far from being perfect and does not enforce a
824 reproducible mode, but it's better than nothing.
825 - Use arc4random() if it's available.
826 While Privoxy doesn't need high quality pseudo-random numbers
827 there's no reason not to use them when we can and this silences
828 a warning emitted by code checkers that can't tell whether or not
830 - Show the FEATURE_EXTERNAL_FILTERS status on the status page.
831 Better late than never. Previously a couple of tests weren't
832 executed as Privoxy-Regression-Test couldn't detect that the
833 FEATURE_EXTERNAL_FILTERS dependency was satisfied.
834 - Ditch FEATURE_IMAGE_DETECT_MSIE.
835 It's an obsolete workaround we inherited from Junkbuster
836 and was already disabled by default.
837 Users that feel the urge to work around issues with
838 image requests coming from an Internet Explorer version
839 from more than 15 years ago can still do this using tags.
840 - Consistently use strdup_or_die() instead of strdup() in
841 cases where allocation failures aren't expected.
842 Using strdup_or_die() allows to remove a couple of explicit
843 error checks which slightly reduces the size of the binary.
844 - Insert a refresh tag into the /client-tags CGI page when
845 serving it while a client-specific tag is temporarily enabled.
846 This makes it less likely that the user ends up
847 looking at tag state that is out of date.
848 - Use absolute URLs in the client-tag forms.
849 It's more consistent with the rest of the CGI page
850 URLs and makes it more convenient to copy the forms
852 - cgi_error_disabled(): Use status code 403 and an appropriate response line
853 - Use a dedicated CGI handler to deal with tag-toggle requests
854 As a result the /client-tags page is now safe to reach without
855 trusted Referer header which makes bookmarking or linking to
857 Finally, refreshing the /client-tags page to show the
858 current state can no longer unintentionally repeat the
859 previous toggle request.
860 - Don't add a "Connection" header for CONNECT requests.
861 Explicitly sending "Connection: close" is not necessary and
862 apparently it causes problems with some forwarding proxies
863 that will close the connection prematurely.
864 Reported by Marc Thomas.
865 - Fix compiler warnings.
868 - rfc2553_connect_to(): Properly detect and log when poll()
869 reached the time out. Previously this was logged as:
870 Could not connect to [...]: No error: 0.
871 which isn't very helpful.

873 - add_tag_for_client(): Set time_to_live properly.
874 Previously the time_to_live was always set for the first tag.
875 Attempts to temporarily enable a tag would result in enabling
876 it permanently unless no tag was enabled already.
877 - Revert r1.165 which didn't perform as advertised.
878 While the idea was to use "https:// when creating links
879 for the user manual on the website", the actual effect
880 was to use "https://" when Privoxy was supposed to serve
881 the user manual itself.
882 Reported by Yossi Zahn on Privoxy-devel@.
883 - socks5_connect(): Fail in case of unsupported address types.
884 Previously they would not be detected right away and
885 Privoxy would fail later on with an error message that
886 didn't make it obvious that the problem was socks-related.
887 So far, no such problems have actually been reported.
888 - socks5_connect(): Properly deal with socks replies that
889 contain IPv6 addresses.
890 Previously parts of the reply were left unread and
891 later on treated as invalid HTTP response data.
892 Fixes #904 reported by Danny Goossen who also provided
893 the initial version of this patch.
895 - Action file improvements:
896 - Unblock 'msdn.microsoft.com/'.
897 It (presumably) isn't used to serve the kind of ads Privoxy should
898 block by default but happens to serve lots of pages with URLs that
899 are likely to result in false positives.
900 Reported by bugreporter1694 in AF#939.
901 - Disable gif deanimation for requests tagged with CSS-REQUEST.
902 The action will ignore content that isn't considered text
903 anyway and explicitly disabling it makes this more obvious
904 if "action" debugging (debug 65536) is enabled while
905 "gif deanimation" debugging (debug 256) isn't.
906 - Explicitly disable HTML filters for requests with CSS-REQUEST tag.
907 The filters are unlikely to break CSS files but executing
908 them without (intentionally) getting any hits is a waste of
909 cpu time and makes the log more noisy when running with

942 - Add a client-header-tagger{client-ip-address} example.
943 - Stop suggesting that Privoxy is an anonymizing proxy.
944 The term could lead to Privoxy users overestimating
945 what it can do on its own (without Tor).

947 Currently most donations are made through the Paypal account
948 managed by Zwiebelfreunde e.V. and a more even distribution

951 - Explicitly mention that Privoxy binaries are built by individuals
952 on their own systems. Buyer beware!
953 - Mention the release feed on the homepage.
954 - Remove a mysterious comment with a GNU FDL link as it isn't
955 useful and could confuse license scanners.
956 In May 2002 it was briefly claimed that "this document" was covered
957 by the GNU FDL. The commit message (r1.5) doesn't explain the motivation
958 or whether all copyright holders were actually asked and agreed to the
959 declared license change.
960 It's thus hard to tell whether or not the license change was legit,
961 but luckily two days later the "doc license" was "put" "back to GPL"
963 At the same time the offending comment with a link to the FDL
964 (not the GPL) was added for no obvious reason.
968 - Bump for-privoxy-version to 3.0.27 as we now rely on untrusted
969 CGI request being rejected with status code 403 (instead of 200).
970 - Update test for /send-stylesheet and add another one

974 - Remove SourceForge references in Copyright header.
975 - Remove a couple of SourceForge references in a comment.
976 While at it, fix the grammar.
977 - Move the site-specific documentation block before the generic one.
978 While most Privoxy installations don't have a site-specific
979 documentation block, in cases were it exists it's likely to
980 be more relevant than the generic one.
981 Showing it first makes it less likely that users stop reading
982 before they reach it, especially on pages that don't fit on
985 - Build system improvements:
986 - Prefer openjade to jade. On some systems Jade produces
987 HTML with unescaped ampersands in URLs.
988 - Prefer OpenSP to SP to be consistent.
989 - Have Docbook generated HTML files be straight ASCII.
990 Dealing with a mixture of ISO-8859 and UTF-8 files is problematic.
991 - Echo the filename to stderr for 'make dok-tidy'.
992 Make it a bit easier to find errors in docbook generated HTML.
993 - Warn when still using select().
994 - Warn when compiling without calloc().
995 - Make it more obvious that the --with-fdsetsize configure switch
996 is pointless if poll() is available.
997 - Remove support for AmigaOS.
998 - Update windows build system to use supported software.
999 The cygwin gcc -mno-cygwin option is no longer supported, so
1000 convert the windows build system to use the cygwin cross-compiler
1001 to build "native" code.
1002 - Add --enable-static-linking option for configure
1003 does the same thing as LDFLAGS=-static; ./configure
1004 but nicer than mixing evars and configure options.
1006 *** Version 3.0.26 stable ***
1009 - Fixed crashes with "listen-addr :8118" (SF Bug #902).
1010 The regression was introduced in 3.0.25 beta and reported
1011 by Marvin Renich in Debian bug #834941.
1013 - General improvements:
1014 - Log when privoxy is toggled on or off via cgi interface.
1015 - Highlight the "Info: Now toggled " on/off log message
1016 in the Windows log viewer.
1017 - Highlight the loading actions/filter file log message
1018 in the Windows log viewer.
1019 - Mention client-specific tags on the toggle page as a
1020 potentionally more appropriate alternative.
1022 - Documentation improvements:
1023 - Update download section on the homepage.
1024 The downloads are available from the website now.
1026 - Remove obsolete reference to mailing lists hosted at SourceForge.
1027 - Update the "Before the Release" section of the developer manual.
1029 - Infrastructure improvements:
1030 - Add perl script to generate an RSS feed for the packages
1031 Submitted by "Unknown".
1033 - Build system improvements:
1034 - strptime.h: fix a compiler warning about ambiguous else.
1035 - configure.in: Check for Docbook goo on the BSDs as well.
1036 - GNUMakefile.in: Let the dok-user target remove temporary files.
1038 *** Version 3.0.25 beta ***
1041 - Always use the current toggle state for new requests.
1042 Previously new requests on reused connections inherited
1043 the toggle state from the previous request even though
1044 the toggle state could have changed.
1045 Reported by Robert Klemme.
1046 - Fixed two buffer-overflows in the (deprecated) static
1047 pcre code. These bugs are not considered security issues
1048 as the input is trusted.
1049 Found with afl-fuzz and ASAN.
1051 - General improvements:
1052 - Added support for client-specific tags which allow Privoxy
1053 admins to pre-define tags that are set for all requests from
1054 clients that previously opted in through the CGI interface.
1055 They are useful in multi-user setups where admins may
1056 want to allow users to disable certain actions and filters
1057 for themselves without affecting others.
1058 In single-user setups they are useful to allow more fine-grained
1059 toggling. For example to disable request blocking while still
1060 crunching cookies, or to disable experimental filters only.
1061 This is an experimental feature, the syntax and behaviour may
1062 change in future versions.
1063 Sponsored by Robert Klemme.
1064 - Dynamic filters and taggers now support a $listen-address variable
1065 which contains the address the request came in on.
1066 For external filters the variable is called $PRIVOXY_LISTEN_ADDRESS.
1067 Original patch contributed by pursievro.
1068 - Add client-header-tagger 'listen-address'.
1069 - Include the listen-address in the log message when logging new requests.
1070 Patch contributed by pursievro.
1071 - Turn invalid max-client-connections values into fatal errors.
1072 - The show-status page now shows whether or not dates before 1970
1073 and after 2038 are expected to be handled properly.
1074 This is mainly useful for Privoxy-Regression-Test but could
1075 also come handy when dealing with time-related support requests.
1076 - On Mac OS X the thread id in log messages are more likely to
1078 - When complaining about missing filters, the filter type is logged
1080 - A couple of harmless coverity warnings were silenced
1081 (CID #161202, CID #161203, CID #161211).
1083 - Action file improvements:
1084 - Filtering is disabled for Range requests to let download resumption
1085 and Windows updates work with the default configuration.
1086 - Unblock ".ardmediathek.de/".
1087 Reported by ThTomate in #932.
1089 - Documentation improvements:
1090 - Add FAQ entry for crashes caused by memory limits.
1091 - Remove obsolete FAQ entry about a bug in PHP 4.2.3.
1092 - Mention the new mailing lists were appropriate.
1093 As the archives have not been migrated, continue to
1094 mention the archives at SF in the contacting section
1096 - Note that the templates should be adjusted if Privoxy is
1097 running as intercepting proxy without getting all requests.
1098 - A bunch of links were converted to https://.
1099 - Rephrase onion service paragraph to make it more obvious
1100 that Tor is involved and that the whole website (and not
1101 just the homepage) is available as onion service.
1102 - Streamline the "More information" section on the homepage further
1103 by additionally ditching the link to the 'See also' section
1104 of the user manual. The section contains mostly links that are
1105 directly reachable from the homepage already and the rest is
1106 not significant enough to get a link from the homepage.
1107 - Change the add-header{} example to set the DNT header
1108 and use a complete section to make copy and pasting
1110 Add a comment to make it obvious that adding the
1111 header is not recommended for obvious reasons.
1112 Using the DNT header as example was suggested by
1114 - Streamline the support-and-service template
1115 Instead of linking to the various support trackers
1116 (whose URLs hopefully change soon), link to the
1117 contact section of the user manual to increase the
1118 chances that users actually read it.
1119 - Add a FAQ entry for tainted sockets.
1120 - More sections in the documentation have stable URLs now.
1121 - FAQ: Explain why 'ping config.privoxy.org' is not expected
1122 to reach a local Privoxy installation.
1123 - Note that donations done through Zwiebelfreunde e.V. currently
1124 can't be checked automatically.
1125 - Updated section regarding starting Privoxy under OS X.
1126 - Use dedicated start instructions for FreeBSD and ElectroBSD.
1127 - Removed release instructions for AIX. They haven't been working
1128 for years and unsurprisingly nobody seems to care.
1129 - Removed obsolete reference to the solaris-dist target.
1130 - Updated the release instructions for FreeBSD.
1131 - Removed unfinished release instructions for Amiga OS and HP-UX 11.
1132 - Added a pointer to the Cygwin Time Machine for getting the last release of
1133 Cygwin version 1.5 to use for building Privoxy on Windows.
1134 - Various typos have been fixed.
1136 - Infrastructure improvements:
1137 - The website is no longer hosted at SourceForge and
1138 can be reached through https now.
1139 - The mailing lists at SourceForge have been deprecated,
1140 you can subscribe to the new ones at: https://lists.privoxy.org/
1141 - Migrating the remaining services from SourceForge is
1142 work in progress (TODO list item #53).
1144 - Build system improvements:
1145 - Add configure argument to optimistically redefine FD_SETSIZE
1146 with the intent to change the maximum number of client
1147 connections Privoxy can handle. Only works with some libcs.
1148 Sponsored by Robert Klemme.
1149 - Let the tarball-dist target skip files in ".git".
1150 - Let the tarball-dist target work in cwds other than current.
1151 - Make the 'clean' target faster when run from a git repository.
1152 - Include tools in the generic distribution.
1153 - Let the gen-dist target work in cwds other than current.
1154 - Sort find output that is used for distribution tarballs
1155 to get reproducible results.
1156 - Don't add '-src' to the name of the tar ball generated by the
1157 gen-dist target. The package isn't a source distribution but a
1159 While at it, use a variable for the name to reduce the chances
1160 that the various references get out of sync and fix the gen-upload
1161 target which was looking in the wrong directory.
1162 - Add regression-tests.action to the files that are distributed.
1163 - The gen-dist target which was broken since 2002 (r1.92) has been fixed.
1164 - Remove genclspec.sh which has been obsolete since 2009.
1165 - Remove obsolete reference to Redhat spec file.
1166 - Remove the obsolete announce target which has been commented out years ago.
1167 - Let rsync skip files if the checksums match.
1169 - Privoxy-Regression-Test:
1170 - Add a "Default level offset" directive which can be used to
1171 change the default level by a given value.
1172 This directive affects all tests located after it until the end
1173 of the file or a another "Default level offset" directive is reached.
1174 The purpose of this directive is to make it more convenient to skip
1175 similar tests in a given file without having to remove or disable
1176 the tests completely.
1177 - Let test level 17 depend on FEATURE_64_BIT_TIME_T
1178 instead of FEATURE_PTHREAD which has no direct connection
1180 - Fix indentation in perldoc examples.
1181 - Don't overlook directives in the first line of the action file.
1182 - Bump version to 0.7.
1183 - Fix detection of the Privoxy version now that https://
1184 is used for the website.
1186 *** Version 3.0.24 stable ***
1188 - Security fixes (denial of service):
1189 - Prevent invalid reads in case of corrupt chunk-encoded content.
1190 CVE-2016-1982. Bug discovered with afl-fuzz and AddressSanitizer.
1191 - Remove empty Host headers in client requests.
1192 Previously they would result in invalid reads. CVE-2016-1983.
1193 Bug discovered with afl-fuzz and AddressSanitizer.
1196 - When using socks5t, send the request body optimistically as well.
1197 Previously the request body wasn't guaranteed to be sent at all
1198 and the error message incorrectly blamed the server.
1199 Fixes #1686 reported by Peter Müller and G4JC.
1200 - Fixed buffer scaling in execute_external_filter() that could lead
1201 to crashes. Submitted by Yang Xia in #892.
1202 - Fixed crashes when executing external filters on platforms like
1203 Mac OS X. Reported by Jonathan McKenzie on ijbswa-users@.
1204 - Properly parse ACL directives with ports when compiled with HAVE_RFC2553.
1205 Previously the port wasn't removed from the host and in case of
1206 'permit-access 127.0.0.1 example.org:80' Privoxy would try (and fail)
1207 to resolve "example.org:80" instead of example.org.
1208 Reported by Pak Chan on ijbswa-users@.
1209 - Check requests more carefully before serving them forcefully
1210 when blocks aren't enforced. Privoxy always adds the force token
1211 at the beginning of the path, but would previously accept it anywhere
1212 in the request line. This could result in requests being served that
1213 should be blocked. For example in case of pages that were loaded with
1214 force and contained JavaScript to create additionally requests that
1215 embed the origin URL (thus inheriting the force prefix).
1216 The bug is not considered a security issue and the fix does not make
1217 it harder for remote sites to intentionally circumvent blocks if
1218 Privoxy isn't configured to enforce them.
1219 Fixes #1695 reported by Korda.
1220 - Normalize the request line in intercepted requests to make rewriting
1221 the destination more convenient. Previously rewrites for intercepted
1222 requests were expected to fail unless $hostport was being used, but
1223 they failed "the wrong way" and would result in an out-of-memory
1224 message (vanilla host patterns) or a crash (extended host patterns).
1225 Reported by "Guybrush Threepwood" in #1694.
1226 - Enable socket lingering for the correct socket.
1227 Previously it was repeatedly enabled for the listen socket
1228 instead of for the accepted socket. The bug was found by
1229 code inspection and did not cause any (reported) issues.
1230 - Detect and reject parameters for parameter-less actions.
1231 Previously they were silently ignored.
1232 - Fixed invalid reads in internal and outdated pcre code.
1233 Found with afl-fuzz and AddressSanitizer.
1234 - Prevent invalid read when loading invalid action files.
1235 Found with afl-fuzz and AddressSanitizer.
1236 - Windows build: Use the correct function to close the event handle.
1237 It's unclear if this bug had a negative impact on Privoxy's behaviour.
1238 Reported by Jarry Xu in #891.
1239 - In case of invalid forward-socks5(t) directives, use the
1240 correct directive name in the error messages. Previously they
1241 referred to forward-socks4t failures.
1242 Reported by Joel Verhagen in #889.
1244 - General improvements:
1245 - Set NO_DELAY flag for the accepting socket. This significantly reduces
1246 the latency if the operating system is not configured to set the flag
1247 by default. Reported by Johan Sintorn in #894.
1248 - Allow to build with mingw x86_64. Submitted by Rustam Abdullaev in #135.
1249 - Introduce the new forwarding type 'forward-webserver'.
1250 Currently it is only supported by the forward-override{} action and
1251 there's no config directive with the same name. The forwarding type
1252 is similar to 'forward', but the request line only contains the path
1253 instead of the complete URL.
1254 - The CGI editor no longer treats 'standard.action' special.
1255 Nowadays the official "standards" are part of default.action
1256 and there's no obvious reason to disallow editing them through
1257 the cgi editor anyway (if the user decided that the lack of
1258 authentication isn't an issue in her environment).
1259 - Improved error messages when rejecting intercepted requests
1260 with unknown destination.
1261 - A couple of log messages now include the number of active threads.
1262 - Removed non-standard Proxy-Agent headers in HTTP snipplets
1263 to make testing more convenient.
1264 - Include the error code for pcre errors Privoxy does not recognize.
1265 - Config directives with numerical arguments are checked more carefully.
1266 - Privoxy's malloc() wrapper has been changed to prevent zero-size
1267 allocations which should only occur as the result of bugs.
1268 - Various cosmetic changes.
1270 - Action file improvements:
1271 - Unblock ".deutschlandradiokultur.de/".
1272 Reported by u302320 in #924.
1273 - Add two fast-redirect exceptions for "yandex.ru".
1274 - Disable filter{banners-by-size} for ".plasmaservice.de/".
1275 - Unblock "klikki.fi/adv/".
1276 - Block requests for "resources.infolinks.com/".
1277 Reported by "Black Rider" on ijbswa-users@.
1278 - Block a bunch of criteo domains.
1279 Reported by Black Rider.
1280 - Block "abs.proxistore.com/abe/".
1281 Reported by Black Rider.
1282 - Disable filter{banners-by-size} for ".black-mosquito.org/".
1283 - Disable fast-redirects for "disqus.com/".
1285 - Documentation improvements:
1286 - FAQ: Explicitly point fingers at ASUS as an example of a
1287 company that has been reported to force malware based on
1288 Privoxy upon its customers.
1289 - Correctly document the action type for a bunch of "multi-value"
1290 actions that were incorrectly documented to be "parameterized".
1291 Reported by Gregory Seidman on ijbswa-users@.
1292 - Fixed the documented type of the forward-override{} action
1293 which is obviously 'parameterized'.
1295 - Website improvements:
1296 - Users who don't trust binaries served by SourceForge
1297 can get them from a mirror. Migrating away from SourceForge
1298 is planned for 2016 (TODO list item #53).
1299 - The website is now available as onion service
1300 (http://jvauzb4sb3bwlsnc.onion/).
1302 *** Version 3.0.23 stable ***
1305 - Fixed a DoS issue in case of client requests with incorrect
1306 chunk-encoded body. When compiled with assertions enabled
1307 (the default) they could previously cause Privoxy to abort().
1308 Reported by Matthew Daley. CVE-2015-1380.
1309 - Fixed multiple segmentation faults and memory leaks in the
1310 pcrs code. This fix also increases the chances that an invalid
1311 pcrs command is rejected as such. Previously some invalid commands
1312 would be loaded without error. Note that Privoxy's pcrs sources
1313 (action and filter files) are considered trustworthy input and
1314 should not be writable by untrusted third-parties. CVE-2015-1381.
1315 - Fixed an 'invalid read' bug which could at least theoretically
1316 cause Privoxy to crash. So far, no crashes have been observed.
1318 - Compiles with --disable-force again. Reported by Kai Raven.
1319 - Client requests with body that can't be delivered no longer
1320 cause pipelined requests behind them to be rejected as invalid.
1321 Reported by Basil Hussain.
1323 - General improvements:
1324 - If a pcrs command is rejected as invalid, Privoxy now logs
1325 the cause of the problem as text. Previously the pcrs error
1327 - The tests are less likely to cause false positives.
1329 - Action file improvements:
1330 - '.sify.com/' is no longer blocked. Apparently it is not actually
1331 a pure tracking site (anymore?). Reported by Andrew on ijbswa-users@.
1332 - Unblock banners on .amnesty.de/ which aren't ads.
1334 - Documentation improvements:
1335 - The 'Would you like to donate?' section now also contains
1337 - The list of supported operating systems has been updated.
1338 - The existence of the SF support and feature trackers has been
1339 deemphasized because they have been broken for months.
1340 Most of the time the mailing lists still work.
1341 - The claim that default.action updates are sometimes released
1342 on their own has been removed. It hasn't happened in years.
1343 - Explicitly mention that Tor's port may deviate from the default
1344 when using a bundle. Requested by Andrew on ijbswa-users@.
1346 *** Version 3.0.22 stable ***
1349 - Fixed a memory leak when rejecting client connections due to
1350 the socket limit being reached (CID 66382). This affected
1351 Privoxy 3.0.21 when compiled with IPv6 support (on most
1352 platforms this is the default). CVE-2015-1030.
1353 - Fixed an immediate-use-after-free bug (CID 66394) and two
1354 additional unconfirmed use-after-free complaints made by
1355 Coverity scan (CID 66391, CID 66376). CVE-2015-1031.
1356 - Actually show the FORCE_PREFIX value on the show-status page.
1357 - Properly deal with Keep-Alive headers with timeout= parameters
1358 If the timeout still can't be parsed, use the configured
1359 timeout instead of preventing the client from keeping the
1360 connection alive. Fixes #3615312/#870 reported by Bernard Guillot.
1361 - Not using any filter files no longer results in warning messages
1362 unless an action file is referencing header taggers or filters.
1363 Reported by Stefan Kurtz in #3614835.
1364 - Fixed a bug that prevented Privoxy from reusing some reusable
1365 connections. Two bit masks with different purpose unintentionally
1366 shared the same bit.
1367 - A couple of additional bugs were discovered by Coverity Scan.
1368 The fixes that are not expected to affect users are not explicitly
1369 mentioned here, for details please have a look at the CVS logs.
1371 - General improvements:
1372 - Introduced negative tag patterns NO-REQUEST-TAG and NO-RESPONSE-TAG.
1373 They apply if no matching tag is found after parsing client or
1375 - Add support for external filters which allow to process the
1376 response body with a script or program written in any language
1377 the platform supports. External filters are enabled with
1378 +external-filter{} after they have been defined in one of the
1379 filter files with a header line starting with "EXTERNAL-FILTER:".
1380 External filter support is experimental, not compiled by default
1381 and known not to work on all platforms.
1382 - Add support for the 'PATCH' method as defined in RFC5789.
1383 - Reject requests with unsupported Expect header values.
1384 Fixes a couple of Co-Advisor tests.
1385 - Normalize the HTTP-version in forwarded requests and responses.
1386 This is an explicit RFC 2616 MUST and RFC 7230 mandates that
1387 intermediaries send their own HTTP-version in forwarded
1389 - Server 'Keep-Alive' headers are no longer forwarded. From a user's
1390 point of view it doesn't really matter, but RFC 2616 (obsolete)
1391 mandates that the header is removed and this fixes a Co-Advisor
1393 - Change declared template file encoding to UTF-8. The templates
1394 already used a subset of UTF-8 anyway and changing the declaration
1395 allows to properly display UTF-8 characters used in the action files.
1396 This change may require existing action files with ISO-8859-1
1397 characters that aren't valid UTF-8 to be converted to UTF-8.
1398 Requested by Sam Chen in #582.
1399 - Do not pass rejected keep-alive timeouts to the server. It might
1400 not have caused any problems (we know of), but doing the right
1401 thing shouldn't hurt either.
1402 - Let log_error() use its own buffer size #define to make changing
1403 the log buffer size slightly less inconvenient.
1404 - Turned single-threaded into a "proper" toggle directive with arguments.
1405 - CGI templates no longer enforce new windows for some links.
1406 - Remove an undocumented workaround ('HOST' header removal) for
1407 an Apple iTunes bug that according to #729900 got fixed in 2003.
1409 - Action file improvements:
1410 - The pattern 'promotions.' is no longer being blocked.
1411 Reported by rakista in #3608540.
1412 - Disable fast-redirects for .microsofttranslator.com/.
1413 - Disable filter{banners-by-size} for .dgb-tagungszentren.de/.
1414 - Add adn.speedtest.net as a site-specific unblocker.
1415 Support request #3612908.
1416 - Disable filter{banners-by-size} for creativecommons.org/.
1417 - Block requests to data.gosquared.com/. Reported by cbug in #3613653.
1418 - Unblock .conrad./newsletter/. Reported by David Bo in #3614238.
1419 - Unblock .bundestag.de/.
1420 - Unblock .rote-hilfe.de/.
1421 - Disable fast-redirects for .facebook.com/plugins/like.php.
1422 - Unblock Stackexchange popup URLs that aren't used to serve ads.
1423 Reported by David Wagner in #3615179.
1424 - Disable fast-redirects for creativecommons.org/.
1425 - Unblock .stopwatchingus.info/.
1426 - Block requests for .adcash.com/script/.
1427 Reported by Tyrexionibus in #3615289.
1428 - Disable HTML filters if the response was tagged as JavaScript.
1429 Filtering JavaScript code with filters intended to deal with HTML
1430 is usually a waste of time and, more importantly, may break stuff.
1431 - Use a custom redirect{} for .washingtonpost.com/wp-apps/imrs\.php\?src=
1432 Previously enabling the 'Advanced' settings (or manually enabling
1433 +fast-redirects{}) prevented some images from being loaded properly.
1434 - Unblock "adina*." Fixes #919 reported by Morton A. Goldberg.
1435 - Block '/.*DigiAd'.
1436 - Unblock 'adele*.'. Reported by Adele Lime in #1663.
1437 - Disable banners-by-size for kggp.de/.
1439 - Filter file improvements & bug fixes:
1440 - Decrease the chances that js-annoyances creates invalid JavaScript.
1441 Submitted by John McGowan on ijbswa-users@.
1442 - Let the msn filter hide 'related' ads again.
1443 - Remove a stray '1' in the 'html-annoyances' filter.
1444 - Prevent img-reorder from messing up img tags with empty src
1445 attributes. Fixes #880 reported by Duncan.
1447 - Documentation improvements:
1448 - Updated the 'Would you like to donate?' section.
1449 - Note that invalid forward-override{} parameter syntax isn't
1450 detected until the parameter is used.
1451 - Add another +redirect{} example: a shortcut for illumos bugs.
1452 - Make it more obvious that many operating systems support log
1453 rotation out of the box.
1454 - Fixed dead links. Reported by Mark Nelson in #3614557.
1455 - Rephrased the 'Why is the configuration so complicated?' answer
1456 to be slightly less condescending. Anonymously suggested in #3615122.
1457 - Be more explicit about accept-intercepted-requests's lack of MITM support.
1458 - Make 'demoronizer' FAQ entries more generic.
1459 - Add an example hostname to the --pre-chroot-nslookup description.
1460 - Add an example for a host pattern that matches an IP address.
1461 - Rename the 'domain pattern' to 'host pattern' as it may
1462 contain IP addresses as well.
1463 - Recommend forward-socks5t when using Tor. It seems to work fine and
1464 modifying the Tor configuration to profit from it hasn't been necessary
1466 - Add another redirect{} example to stress that redirect loops can
1467 and should be avoided.
1468 - The usual spelling and grammar fixes. Parts of them were
1469 reported by Reuben Thomas in #3615276.
1470 - Mention the PCRS option letters T and D in the filter section.
1471 - Clarify that handle-as-empty-doc-returns-ok is still useful
1472 and will not be removed without replacement.
1473 - Note that security issues shouldn't be reported using the bug tracker.
1474 - Clarify what Privoxy does if both +block{} and +redirect{} apply.
1475 - Removed the obsolete bookmarklets section.
1477 - Build system improvements:
1478 - Let --with-group properly deal with secondary groups.
1479 Patch submitted by Anatoly Arzhnikov in #3615187.
1480 - Fix web-actions target.
1481 - Add a web-faq target that only updates the FAQ on the webserver.
1482 - Remove already-commented-out non-portable DOSFILTER alternatives.
1483 - Remove the obsolete targets dok-put and dok-get.
1484 - Add a sf-shell target.
1486 *** Version 3.0.21 stable ***
1489 - On POSIX-like platforms, network sockets with file descriptor
1490 values above FD_SETSIZE are properly rejected. Previously they
1491 could cause memory corruption in configurations that allowed
1492 the limit to be reached.
1493 - Proxy authentication headers are removed unless the new directive
1494 enable-proxy-authentication-forwarding is used. Forwarding the
1495 headers potentially allows malicious sites to trick the user
1496 into providing them with login information.
1497 Reported by Chris John Riley.
1498 - Compiles on OS/2 again now that unistd.h is only included
1499 on platforms that have it.
1501 - General improvements:
1502 - The show-status page shows the FEATURE_STRPTIME_SANITY_CHECKS status.
1503 - A couple of assert()s that could theoretically dereference
1504 NULL pointers in debug builds have been relocated.
1505 - Added an LSB info block to the generic start script.
1506 Based on a patch from Natxo Asenjo.
1507 - The max-client-connections default has been changed to 128
1508 which should be more than enough for most setups.
1510 - Action file improvements:
1511 - Block rover.ebay./ar.*\&adtype= instead of "/.*\&adtype=" which
1512 caused too man false positives.
1513 Reported by u302320 in #360284, additional feedback from Adam Piggott.
1514 - Unblock '.advrider.com/' and '/.*ADVrider'.
1515 Anonymously reported in #3603636.
1516 - Stop blocking '/js/slider\.js'.
1517 Reported by Adam Piggott in #3606635 and _lvm in #2791160.
1519 - Filter file improvements:
1520 - Added an iframes filter.
1522 - Documentation improvements:
1523 - The whole GPLv2 text is included in the user manual now,
1524 so Privoxy can serve it itself and the user can read it
1525 without having to wade through GPLv3 ads first.
1526 - Properly numbered and underlined a couple of section titles
1527 in the config that where previously overlooked due to a flaw
1528 in the conversion script. Reported by Ralf Jungblut.
1529 - Improved the support instruction to hopefully make it harder to
1530 unintentionally provide insufficient information when requesting
1531 support. Previously it wasn't obvious that the information we need
1532 in bug reports is usually also required in support requests.
1533 - Removed documentation about packages that haven't been provided
1536 - Privoxy-Regression-Test:
1537 - Only log the test number when not running in verbose mode
1538 The position of the test is rarely relevant and it previously
1539 wasn't exactly obvious which one of the numbers was useful to
1540 repeat the test with --test-number.
1542 - GNUmakefile improvements:
1543 - Factor generate-config-file out of config-file to make testing
1545 - The clean target now also takes care of patch leftovers.
1547 *** Version 3.0.20 beta ***
1550 - Client sockets are now properly shutdown and drained before being
1551 closed. This fixes page truncation issues with clients that aggressively
1552 pipeline data on platforms that otherwise discard already written data.
1553 The issue mainly affected Opera users and was initially reported
1554 by Kevin in #3464439, szotsaki provided additional information to track
1556 - Fix latency calculation for shared connections (disabled by default).
1557 It was broken since their introduction in 2009. The calculated latency
1558 for most connections would be 0 in which case the timeout detection
1559 failed to account for the real latency.
1560 - Reject URLs with invalid port. Previously they were parsed incorrectly and
1561 characters between the port number and the first slash were silently
1562 dropped as shown by curl test 187.
1563 - The default-server-timeout and socket-timeout directives accept 0 as
1565 - Fix a race condition on Windows that could cause Privoxy to become
1566 unresponsive after toggling it on or off through the taskbar icon.
1567 Reported by Tim H. in #3525694.
1568 - Fix the compilation on Windows when configured without IPv6 support.
1569 - Fix an assertion that could cause debug builds to abort() in case of
1570 socks5 connection failures with "debug 2" enabled.
1571 - Fix an assertion that could cause debug builds to abort() if a filter
1572 contained nul bytes in the replacement text.
1574 - General improvements:
1575 - Significantly improved keep-alive support for both client and server
1577 - New debug log level 65536 which logs all actions that were applied to
1579 - New directive client-header-order to forward client headers in a
1580 different order than the one in which they arrived.
1581 - New directive tolerate-pipelining to allow client-side pipelining.
1582 If enabled (3.0.20 beta enables it by default), Privoxy will keep
1583 pipelined client requests around to deal with them once the current
1584 request has been served.
1585 - New --config-test option to let Privoxy exit after checking whether or not
1586 the configuration seems valid. The limitations noted in TODO #22 and #23
1587 still apply. Based on a patch by Ramkumar Chinchani.
1588 - New limit-cookie-lifetime{} action to let cookies expire before the end
1589 of the session. Suggested by Rick Sykes in #1049575.
1590 - Increase the hard-coded maximum number of actions and filter files from
1591 10 to 30 (each). It doesn't significantly affect Privoxy's memory usage
1592 and recompiling wasn't an option for all Privoxy users that reached the
1594 - Add support for chunk-encoded client request bodies. Previously
1595 chunk-encoded request bodies weren't guaranteed to be forwarded correctly,
1596 so this can also be considered a bug fix although chunk-encoded request
1597 bodies aren't commonly used in the real world.
1598 - Add support for Tor's optimistic-data SOCKS extension, which can reduce the
1599 latency for requests on newly created connections. Currently only the
1600 headers are sent optimistically and only if the client request has already
1601 been read completely which rules out requests with large bodies.
1602 - After preventing the client from pipelining, don't signal keep-alive
1603 intentions. When looking at the response headers alone, it previously
1604 wasn't obvious from the client's perspective that no additional responses
1606 - Stop considering client sockets tainted after receiving a request with body.
1607 It hasn't been necessary for a while now and unnecessarily causes test
1608 failures when using curl's test suite.
1609 - Allow HTTP/1.0 clients to signal interest in keep-alive through the
1610 Proxy-Connection header. While such client are rare in the real world, it
1611 doesn't hurt and couple of curl tests rely on it.
1612 - Only remove duplicated Content-Type headers when filters are enabled.
1613 If they are not it doesn't cause ill effects and the user might not want it.
1614 Downgrade the removal message to LOG_LEVEL_HEADER to clarify that it's not
1615 an error in Privoxy and is unlikely to cause any problems in general.
1616 Anonymously reported in #3599335.
1617 - Set the socket option SO_LINGER for the client socket.
1618 - Move several variable declarations to the beginning of their code block.
1619 It's required when compiling with gcc 2.95 which is still used on some
1620 platforms. Initial patch submitted by Simon South in #3564815.
1621 - Optionally try to sanity-check strptime() results before trusting them.
1622 Broken strptime() implementations have caused problems in the past and
1623 the most recent offender seems to be FreeBSD's libc (standards/173421).
1624 - When filtering is enabled, let Range headers pass if the range starts at
1625 the beginning. This should work around (or at least reduce) the video
1626 playback issues with various Apple clients as reported by Duc in #3426305.
1627 - Do not confuse a client hanging up with a connection time out. If a client
1628 closes its side of the connection without sending a request line, do not
1629 send the CLIENT_CONNECTION_TIMEOUT_RESPONSE, but report the condition
1631 - Allow closing curly braces as part of action values as long as they are
1633 - On Windows, the logfile is now written before showing the GUI error
1634 message which blocks until the user acknowledges it.
1635 Reported by Adriaan in #3593603.
1636 - Remove an unreasonable parameter limit in the CGI interface. The new
1637 parameter limit depends on the memory available and is currently unlikely
1638 to be reachable, due to other limits in both Privoxy and common clients.
1639 Reported by Andrew on ijbswa-users@.
1640 - Decrease the chances of parse failures after requests with unsupported
1641 methods were sent to the CGI interface.
1643 - Action file improvements:
1644 - Remove the comment that indicated that updated default.action versions
1645 are released on their own.
1646 - Block 'optimize.indieclick.com/' and 'optimized-by.rubiconproject.com/'
1647 - Unblock 'adjamblog.wordpress.com/' and 'adjamblog.files.wordpress.com/'.

1686 Fixes #3413827 submitted by David Bo.
1687 - Add two unblock patterns for popup radio and TV players.
1688 Submitted by Adam Piggott in #3596089.
1690 - Filter file improvements & bug fixes:
1691 - Add a referer tagger.
1692 - Reduce the likelihood that the google filter messes up HTML-generating
1693 JavaScript. Reported by Zeno Kugy in #3520260.
1695 - Documentation improvements:
1696 - Revised all OS X sections due to new packaging module (OSXPackageBuilder).
1697 - Update the list of supported operating systems to clarify that all Windows
1698 versions after 95 are expected to work and note that the platform-specific
1699 code for AmigaOS and QNX currently isn't maintained.
1700 - Update 'Signals' section, the only explicitly handled signals are SIGINT,
1702 - Add Haiku to the list of operating systems on which Privoxy is known to
1704 - Add DragonFly to the list of BSDs on which Privoxy is known to run.
1705 - Removed references to redhat-specific documentation set since it no longer
1707 - Removed references to building PDFs since we no longer do so.
1708 - Multiple listen-address directives are supported since 3.0.18, correct the
1709 documentation to say so.
1710 - Remove bogus section about long and short being preferable to int.
1711 - Corrected some Internet JunkBuster references to Privoxy.
1712 - Removed references to www.junkbusters.com since it is no longer
1713 maintained. Reported by Angelina Matson.
1714 - Various grammar and spelling corrections
1715 - Add a client-header-tagger{} example for disabling filtering for range
1717 - Correct a URL in the "Privoxy with Tor" FAQ.
1718 - Spell 'refresh-tags' correctly. Reported by Don in #3571927.
1719 - Sort manpage options alphabetically.
1720 - Remove an incorrect sentence in the toggle section. The toggle state
1721 doesn't affect whether or not the Windows version uses the tray icon.
1722 Reported by Zeno Kugy in #3596395.
1723 - Add new contributors since 3.0.19.
1725 - Log message improvements:
1726 - When stopping to watch a client socket due to pipelining, additionally log
1728 - Log the client socket and its condition before closing it. This makes it
1729 more obvious that the socket actually gets closed and should help when
1730 diagnosing problems like #3464439.
1731 - In case of SOCKS5 failures, do not explicitly log the server's response.
1732 It hasn't helped so far and the response can already be logged by enabling
1733 "debug 32768" anyway. This reverts v1.81 and the follow-up bug fix v1.84.
1734 - Relocate the connection-accepted message from listen_loop() to serve().
1735 This way it's printed by the thread that is actually serving the
1736 connection which is nice when grepping for thread ids in log files.
1739 - Remove compatibility layer for versions prior to 3.0 since it has been
1740 obsolete for more than 10 years now.
1741 - Remove the ijb_isupper() and ijb_tolower() macros from parsers.c since
1742 they aren't used in this file.
1743 - Removed the 'Functions declared include:' comment sections since they tend
1744 to be incomplete, incorrect and out of date and the benefit seems
1746 - Various comment grammar and comprehensibility improvements.
1747 - Remove a pointless fflush() call in chat(). Flushing all streams pretty
1748 much all the time for no obvious reason is ridiculous.
1749 - Relocate ijb_isupper()'s definition to project.h and get the ijb_tolower()
1750 definition from there, too.
1751 - Relocate ijb_isdigit()'s definition to project.h.
1752 - Rename ijb_foo macros to privoxy_foo.
1753 - Add malloc_or_die() which will allow to simplify code paths where malloc()
1754 failures don't need to be handled gracefully.
1755 - Add strdup_or_die() which will allow to simplify code paths where strdup()
1756 failures don't need to be handled gracefully.
1757 - Replace strdup() calls with strdup_or_die() calls where it's safe and
1758 simplifies the code.
1759 - Fix white-space around parentheses.
1760 - Add missing white-space behind if's and the following parentheses.
1761 - Unwrap a memcpy() call in resolve_hostname_to_ip().
1762 - Declare pcrs_get_delimiter()'s delimiters[] static const.
1763 - Various optimisations to remove dead code and merge inefficient code
1764 structures for improved clarity, performance or code compactness.
1765 - Various data type corrections.
1766 - Change visibility of several code segments when compiling without
1767 FEATURE_CONNECTION_KEEP_ALIVE enabled for clarity.
1768 - In pcrs_get_delimiter(), do not use delimiters outside the ASCII range.
1769 Fixes a clang complaint.
1770 - Fix an error message in get_last_url() nobody is supposed to see.
1771 Reported by Matthew Fischer in #3507301.
1772 - Fix a typo in the no-zlib-support complaint. Patch submitted by Matthew
1773 Fischer in #3507304.
1774 - Shorten ssplit()'s prototype by removing the last two arguments. We always
1775 want to skip empty fields and ignore leading delimiters, so having
1776 parameters for this only complicates the API.
1777 - Use an enum for the type of the action value.
1778 - Rename action_name's member takes_value to value_type as it isn't used as
1780 - Turn family mismatches in match_sockaddr() into fatal errors.
1781 - Let enlist_unique_header() verify that the caller didn't pass a header
1782 containing either \r or \n.
1783 - Change the hashes used in load_config() to unsigned int. That's what
1784 hash_string() actually returns and using a potentially larger type
1786 - Use privoxy_tolower() instead of vanilla tolower() with manual casting of
1788 - Catch ssplit() failures in parse_cgi_parameters().
1790 - Privoxy-Regression-Test:
1791 - Add an 'Overwrite condition' directive to skip any matching tests before
1792 it. As it has a global scope, using it is more convenient than clowning
1793 around with the Ignore directive.
1794 - Log to STDOUT instead of STDERR.
1795 - Include the Privoxy version in the output.
1796 - Various grammar and spelling corrections in documentation and code.
1797 - Additional tests for range requests with filtering enabled.
1798 - Tests with mostly invalid range request.
1799 - Add a couple of hide-if-modified-since{} tests with different date formats.
1800 - Cleaned up the format of the regression-tests.action file to match the
1801 format of default.action.
1802 - Remove the "Copyright" line from print_version(). When using --help, every
1803 line of screen space matters and thus shouldn't be wasted on things the
1804 user doesn't care about.
1806 - Privoxy-Log-Parser:
1807 - Improve the --statistics performance by skipping sanity checks for input
1808 that shouldn't affect the results anyway. Add a --strict-checks option
1809 that enables some of the checks again, just in case anybody cares.
1810 - The distribution of client requests per connection is included in
1811 the --statistic output.
1812 - The --accept-unknown-messages option has been removed and the behavior
1814 - Accept and (mostly) highlight new log messages introduced with
1818 - Bump generated Firefox version to 17.
1820 - GNUmakefile improvements:
1821 - The dok-tidy target no longer taints documents with a tidy-mark
1822 - Change RA_MODE from 0664 to 0644. Suggested by Markus Dittrich in
1824 - Remove tidy's clean flag as it changes the scope of attributes.
1825 Link-specific colors end up being applied to all text. Reported by Adam
1826 Piggott in #3569551.
1827 - Leave it up to the user whether or not smart tags are inserted.
1828 - Let w3m itself do the line wrapping for the config file. It works better
1829 than fmt as it can honour pre tags causing less unintentional line breaks.
1830 - Ditch a pointless '-r' passed to rm to delete files.
1831 - The config-file target now requires less manual intervention and updates
1832 the original config.
1833 - Change WDUMP to generate ASCII. Add WDUMP_UTF8 to allow UTF-8 in the
1834 AUTHORS file so the names are right.
1835 - Stop pretending that lynx and links are supported for the documentation.
1837 - configure improvements:
1838 - On Haiku, do not pass -lpthread to the compiler. Haiku's pthreads
1839 implementation is contained in its system library, libroot, so no
1840 additional library needs to be searched.
1841 Patch submitted by Simon South in #3564815.
1842 - Additional Haiku-specific improvements. Disable checks intended for
1843 multi-user systems as Haiku is presently single-user. Group Haiku-specific
1844 settings in their own section, following the pattern for Solaris, OS/2 and
1845 AmigaOS. Add additional library-related settings to remove the need for
1846 providing configure with custom LDFLAGS.
1847 Submitted by Simon South in #3574538.
1849 *** Version 3.0.19 Stable ***
1852 - Prevent a segmentation fault when de-chunking buffered content.
1853 It could be triggered by malicious web servers if Privoxy was
1854 configured to filter the content and running on a platform
1855 where SIZE_T_MAX isn't larger than UINT_MAX, which probably
1856 includes most 32-bit systems. On those platforms, all Privoxy
1857 versions before 3.0.19 appear to be affected.
1858 To be on the safe side, this bug should be presumed to allow
1859 code execution as proving that it doesn't seems unrealistic.
1860 - Do not expect a response from the SOCKS4/4A server until it
1861 got something to respond to. This regression was introduced
1862 in 3.0.18 and prevented the SOCKS4/4A negotiation from working.
1863 Reported by qqqqqw in #3459781.
1865 - General improvements:
1866 - Fix an off-by-one in an error message about connect failures.
1867 - Use a GNUMakefile variable for the webserver root directory and
1868 update the path. Sourceforge changed it which broke various
1869 web-related targets.
1870 - Update the CODE_STATUS description.
1872 *** Version 3.0.18 Stable ***
1875 - If a generated redirect URL contains characters RFC 3986 doesn't
1876 permit, they are (re)encoded. Not doing this makes Privoxy versions
1877 from 3.0.5 to 3.0.17 susceptible to HTTP response splitting (CWE-113)
1878 attacks if the +fast-redirects{check-decoded-url} action is used.
1879 - Fix a logic bug that could cause Privoxy to reuse a server
1880 socket after it got tainted by a server-header-tagger-induced
1881 block that was triggered before the whole server response had
1882 been read. If keep-alive was enabled and the request following
1883 the blocked one was to the same host and using the same forwarding
1884 settings, Privoxy would send it on the tainted server socket.
1885 While the server would simply treat it as a pipelined request,
1886 Privoxy would later on fail to properly parse the server's
1887 response as it would try to parse the unread data from the
1888 first response as server headers for the second one.
1889 Regression introduced in 3.0.17.
1890 - When implying keep-alive in client_connection(), remember that
1891 the client didn't. Fixes a regression introduced in 3.0.13 that
1892 would cause Privoxy to wait for additional client requests after
1893 receiving a HTTP/1.1 request with "Connection: close" set
1894 and connection sharing enabled.
1895 With clients which terminates the client connection after detecting
1896 that the whole body has been received it doesn't really matter,
1897 but with clients that don't the connection would be kept open until
1899 - Fix a subtle race condition between prepare_csp_for_next_request()
1900 and sweep(). A thread preparing itself for the next client request
1901 could briefly appear to be inactive.
1902 If all other threads were already using more recent files,
1903 the thread could get its files swept away under its feet.
1904 So far this has only been reproduced while stress testing in
1905 valgrind while touching action files in a loop. It's unlikely
1906 to have caused any actual problems in the real world.
1907 - Disable filters if SDCH compression is used unless filtering is forced.
1908 If SDCH was combined with a supported compression algorithm, Privoxy
1909 previously could try to decompress it and ditch the Content-Encoding
1910 header even though the SDCH compression wasn't dealt with.
1911 Reported by zebul666 in #3225863.
1912 - Make a copy of the --user value and only mess with that when splitting
1913 user and group. On some operating systems modifying the value directly
1914 is reflected in the output of ps and friends and can be misleading.
1915 Reported by zepard in #3292710.
1916 - If forwarded-connect-retries is set, only retry if Privoxy is actually
1917 forwarding the request. Previously direct connections would be retried
1919 - Fixed a small memory leak when retrying connections with IPv6
1921 - Remove an incorrect assertion in compile_dynamic_pcrs_job_list()
1922 It could be triggered by a pcrs job with an invalid pcre
1923 pattern (for example one that contains a lone quantifier).
1924 - If the --user argument user[.group] contains a dot, always bail out
1925 if no group has been specified. Previously the intended, but undocumented
1926 (and apparently untested), behaviour was to try interpreting the whole
1927 argument as user name, but the detection was flawed and checked for '0'
1928 instead of '\0', thus merely preventing group names beginning with a zero.
1929 - In html_code_map[], use a numeric character reference instead of '
1930 which wasn't standardized before XHTML 1.0.
1931 - Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION
1932 and shut down through http://config.privoxy.org/die
1933 - In get_actions(), fix the "temporary" backwards compatibility hack
1934 to accept block actions without reason.
1935 It also covered other actions that should be rejected as invalid.
1936 Reported by Billy Crook.
1938 - General improvements:
1939 - Privoxy can (re)compress buffered content before delivering
1940 it to the client. Disabled by default as most users wouldn't
1942 - The +fast-redirects{check-decoded-url} action checks URL
1943 segments separately. If there are other parameters behind
1944 the redirect URL, this makes it unnecessary to cut them off
1945 by additionally using a +redirect{} pcrs command.
1946 Initial patch submitted by Jamie Zawinski in #3429848.
1947 - When loading action sections, verify that the referenced filters
1948 exist. Currently missing filters only result in an error message,
1949 but eventually the severity will be upgraded to fatal.
1950 - Allow to bind to multiple separate addresses.
1951 Patch set submitted by Petr Pisar in #3354485.
1952 - Set socket_error to errno if connecting fails in rfc2553_connect_to().
1953 Previously rejected direct connections could be incorrectly reported
1954 as DNS issues if Privoxy was compiled with IPv6 support.
1955 - Adjust url_code_map[] so spaces are replaced with %20 instead of '+'
1956 While '+' can be used by client's submitting form data, this is not
1957 actually what Privoxy is using the lookups for. This is more of a
1958 cosmetic issue and doesn't fix any known problems.
1959 - When compiled without FEATURE_FAST_REDIRECTS, do not silently
1960 ignore +fast-redirect{} directives
1961 - Added a workaround for GNU libc's strptime() reporting negative
1962 year values when the parsed year is only specified with two digits.
1963 On affected systems cookies with such a date would not be turned
1964 into session cookies by the +session-cookies-only action.
1965 Reported by Vaeinoe in #3403560
1966 - Fixed bind failures with certain GNU libc versions if no non-loopback
1967 IP address has been configured on the system. This is mainly an issue
1968 if the system is using DHCP and Privoxy is started before the network
1969 is completely configured.
1970 Reported by Raphael Marichez in #3349356.
1971 Additional insight from Petr Pisar.
1972 - Privoxy log messages now use the ISO 8601 date format %Y-%m-%d.
1973 It's only slightly longer than the old format, but contains
1974 the full date including the year and allows sorting by date
1975 (when grepping in multiple log files) without hassle.
1976 - In get_last_url(), do not bother trying to decode URLs that do
1977 not contain at least one '%' sign. It reduces the log noise and
1978 a number of unnecessary memory allocations.
1979 - In case of SOCKS5 failures, dump the socks response in the log message.
1980 - Simplify the signal setup in main().
1981 - Streamline socks5_connect() slightly.
1982 - In socks5_connect(), require a complete socks response from the server.
1983 Previously Privoxy didn't care how much data the server response
1984 contained as long as the first two bytes contained the expected
1985 values. While at it, shrink the buffer size so Privoxy can't read
1986 more than a whole socks response.
1987 - In chat(), do not bother to generate a client request in case of
1988 direct CONNECT requests. It will not be used anyway.
1989 - Reduce server_last_modified()'s stack size.
1990 - Shorten get_http_time() by using strftime().
1991 - Constify the known_http_methods pointers in unknown_method().
1992 - Constify the time_formats pointers in parse_header_time().
1993 - Constify the formerly_valid_actions pointers in action_used_to_be_valid().
1994 - Introduce a GNUMakefile MAN_PAGE variable that defaults to privoxy.1.
1995 The Debian package uses section 8 for the man page and this
1996 should simplify the patch.
1997 - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
1998 - In block_url(), ditch the obsolete workaround for ancient Netscape versions
1999 that supposedly couldn't properly deal with status code 403.
2000 - Remove a useless NULL pointer check in load_trustfile().
2001 - Remove two useless NULL pointer checks in load_one_re_filterfile().
2002 - Change url_code_map[] from an array of pointers to an array of arrays
2003 It removes an unnecessary layer of indirection and on 64bit system reduces
2004 the size of the binary a bit.
2005 - Fix various typos. Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
2006 - Add a dok-tidy GNUMakefile target to clean up the messy HTML
2007 generated by the other dok targets.
2008 - GNUisms in the GNUMakefile have been removed.
2009 - Change the HTTP version in static responses to 1.1
2010 - Synced config.sub and config.guess with upstream
2011 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
2012 - Add a dedicated function to parse the values of toggles. Reduces duplicated
2013 code in load_config() and provides better error handling. Invalid or missing
2014 toggle values are now a fatal error instead of being silently ignored.
2015 - Terminate HTML lines in static error messages with \n instead of \r\n.
2016 - Simplify cgi_error_unknown() a bit.
2017 - In LogPutString(), don't bother looking at pszText when not
2018 actually logging anything.
2019 - Change ssplit()'s fourth parameter from int to size_t.
2020 Fixes a clang complaint.
2021 - Add a warning that the statistics currently can't be trusted.
2022 Mention Privoxy-Log-Parser's --statistics option as
2023 an alternative for the time being.
2024 - In rfc2553_connect_to(), start setting cgi->error_message on error.
2025 - Change the expected status code returned for http://p.p/die depending
2026 on whether or not FEATURE_GRACEFUL_TERMINATION is available.
2027 - In cgi_die(), mark the client connection for closing.
2028 If the client will fetch the style sheet through another connection
2029 it gets the main thread out of the accept() state and should thus
2030 trigger the actual shutdown.
2031 - Add a proper CGI message for cgi_die().
2032 - Don't enforce a logical line length limit in read_config_line().
2033 - Slightly refactor server_last_modified() to remove useless gmtime*() calls.
2034 - In get_content_type(), also recognize '.jpeg' as JPEG extension.
2035 - Add '.png' to the list of recognized file extensions in get_content_type().
2036 - In block_url(), consistently use the block reason "Request blocked by Privoxy"
2037 In two places the reason was "Request for blocked URL" which hides the
2038 fact that the request got blocked by Privoxy and isn't necessarily
2039 correct as the block may be due to tags.
2040 - In listen_loop(), reload the configuration files after accepting
2041 a new connection instead of before.
2042 Previously the first connection that arrived after a configuration
2043 change would still be handled with the old configuration.
2044 - In chat()'s receive-data loop, skip a client socket check if
2045 the socket will be written to right away anyway. This can
2046 increase the transfer speed for unfiltered content on fast
2047 network connections.
2048 - The socket timeout is used for SOCKS negotiations as well which
2049 previously couldn't timeout.
2050 - Don't keep the client connection alive if any configuration file
2051 changed since the time the connection came in. This is closer to
2052 Privoxy's behaviour before keep-alive support for client connection
2053 has been added and also less confusing in general.
2054 - Treat all Content-Type header values containing the pattern
2055 'script' as a sign of text. Reported by pribog in #3134970.
2057 - Action file improvements:
2058 - Moved the site-specific block pattern section below the one for the
2059 generic patterns so for requests that are matched in both, the block
2060 reason for the domain is shown which is usually more useful than showing
2061 the one for the generic pattern.
2062 - Remove -prevent-compression from the fragile alias. It's no longer
2063 used anywhere by default and isn't known to break stuff anyway.
2064 - Add a (disabled) section to block various Facebook tracking URLs.
2065 Reported by Dan Stahlke in #3421764.
2066 - Add a (disabled) section to rewrite and redirect click-tracking
2067 URLs used on news.google.com.
2068 Reported by Dan Stahlke in #3421755.
2069 - Unblock linuxcounter.net/.
2070 Reported by Dan Stahlke in #3422612.
2071 - Block 'www91.intel.com/' which is used by Omniture.
2072 Reported by Adam Piggott in #3167370.
2073 - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
2074 Reminded by tceverling in #2790091.
2075 - Add ".ivwbox.de/" to the "Cross-site user tracking" section.
2076 Reported by Nettozahler in #3172525.
2077 - Unblock and fast-redirect ".awin1.com/.*=http://".
2078 Reported by Adam Piggott in #3170921.
2079 - Block "b.collective-media.net/".
2080 - Widen the Debian popcon exception to "qa.debian.org/popcon".
2081 Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
2082 - Block ".gemius.pl/" which only seems to be used for user tracking.
2083 Reported by johnd16 in #3002731. Additional input from Lee and movax.
2084 - Disable banners-by-size filters for '.thinkgeek.com/'.
2085 The filter only seems to catch pictures of the inventory.
2086 - Block requests for 'go.idmnet.bbelements.com/please/showit/'.
2087 Reported by kacperdominik in #3372959.
2088 - Unblock adainitiative.org/.
2089 - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'.
2090 - Add a fast-redirects exception for webcache.googleusercontent.com/.
2091 - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/.
2093 - Filter file improvements:
2094 - Let the yahoo filter hide '.ads'.
2095 - Let the msn filter hide overlay ads for Facebook 'likes' in search
2096 results and elements with the id 's_notf_div'. They only seem to be
2097 used to advertise site 'enhancements'.
2098 - Let the js-events filter additionally disarm setInterval().
2099 Suggested by dg1727 in #3423775.
2101 - Documentation improvements:
2102 - Clarify the effect of compiling Privoxy with zlib support.
2103 Suggested by dg1727 in #3423782.
2104 - Point out that the SourceForge messaging system works like a black
2105 hole and should thus not be used to contact individual developers.
2106 - Mention some of the problems one can experience when not explicitly
2107 configuring an IP addresses as listen address.
2108 - Explicitly mention that hostnames can be used instead of IP addresses
2109 for the listen-address, that only the first address returned will be
2110 used and what happens if the address is invalid.
2111 Requested by Calestyo in #3302213.
2113 - Log message improvements:
2114 - If only the server connection is kept alive, do not pretend to
2115 wait for a new client request.
2116 - Remove a superfluous log message in forget_connection().
2117 - In chat(), properly report missing server responses as such
2118 instead of calling them empty.
2119 - In forwarded_connect(), fix a log message nobody should ever see.
2120 - Fix a log message in socks5_connect(), a failed write operation
2121 was logged as failed read operation.
2122 - Let load_one_actions_file() properly complain about a missing
2123 '{' at the beginning of the file.
2124 Simply stating that a line is invalid isn't particularly helpful.
2125 - Do not claim to listen on a socket until Privoxy actually does.
2126 Patch submitted by Petr Pisar #3354485
2127 - Prevent a duplicated LOG_LEVEL_CLF message when sending out
2128 the "no-server-data" response.
2129 - Also log the client socket when dropping a connection.
2130 - Include the destination host in the 'Request ... marked for
2131 blocking. limit-connect{...} doesn't allow CONNECT ...' message
2132 Patch submitted by Saperski in #3296250.
2133 - Prevent a duplicated log message if none of the resolved IP
2134 addresses were reachable.
2135 - In connect_to(), do not pretend to retry if forwarded-connect-retries
2137 - When a specified user or group can't be found, put the name in
2138 single-quotes when logging it.
2139 - In rfc2553_connect_to(), explain getnameinfo() errors better.
2140 - Remove a useless log message in chat().
2141 - When retrying to connect, also log the maximum number of connection
2143 - Rephrase a log message in compile_dynamic_pcrs_job_list().
2144 Divide the error code and its meaning with a colon. Call the pcrs
2145 job dynamic and not the filter. Filters may contain dynamic and
2146 non-dynamic pcrs jobs at the same time. Only mention the name of
2147 the filter or tagger, but don't claim it's a filter when it could
2149 - In a fatal error message in load_one_actions_file(), cover both
2150 URL and TAG patterns.
2151 - In pcrs_strerror(), properly report unknown positive error code
2152 values as such. Previously they were handled like 0 (no error).
2153 - In compile_dynamic_pcrs_job_list(), also log the actual error code as
2154 pcrs_strerror() doesn't handle all errors reported by pcre.
2155 - Don't bother trying to continue chatting if the client didn't ask for it.
2156 Reduces log noise a bit.
2157 - Make two fatal error message in load_one_actions_file() more descriptive.
2158 - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'.
2159 - In load_file(), log a message if opening a file failed.
2160 The CGI error message alone isn't too helpful.
2161 - In connection_destination_matches(), improve two log messages
2162 to help understand why the destinations don't match.
2163 - Rephrase a log message in serve(). Client request arrival
2164 should be differentiated from closed client connections now.
2165 - In serve(), log if a client connection isn't reused due to a
2166 configuration file change.
2167 - Let mark_server_socket_tainted() always mark the server socket tainted,
2168 just don't talk about it in cases where it has no effect. It doesn't change
2169 Privoxy's behaviour, but makes understanding the log file easier.
2172 - Added a --disable-ipv6-support switch for platforms where support
2173 is detected but doesn't actually work.
2174 - Do not check for the existence of strerror() and memmove() twice
2175 - Remove a useless test for setpgrp(2). Privoxy doesn't need it and
2176 it can cause problems when cross-compiling.
2177 - Rename the --disable-acl-files switch to --disable-acl-support.
2178 Since about 2001, ACL directives are specified in the standard
2180 - Update the URL of the 'Removing outdated PCRE version after the
2181 next stable release' posting. The old URL stopped working after
2182 one of SF's recent site "optimizations". Reported by Han Liu.
2184 - Privoxy-Regression-Test:
2185 - Added --shuffle-tests option to increase the chances of detection race conditions.
2186 - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy.
2187 - Added tests for missing socks4 and socks4a forwarders.
2188 - The --privoxy-address option now works with IPv6 addresses containing brackets, too.
2189 - Perform limited sanity checks for parameters that are supposed to have numerical values.
2190 - Added a --sleep-time option to specify a number of seconds to
2191 sleep between tests, defaults to 0.
2192 - Disable the range-requests tagger for tests that break if it's enabled.
2193 - Log messages use the ISO 8601 date format %Y-%m-%d.
2194 - Fix spelling in two error messages.
2195 - In the --help output, include a list of supported tests and their default levels.
2196 - Adjust the tests to properly deal with FEATURE_TOGGLE being disabled.
2198 - Privoxy-Log-Parser:
2199 - Perform limited sanity checks for command line parameters that
2200 are supposed to have numerical values.
2201 - Implement a --unbreak-lines-only option to try to revert MUA breakage.
2202 - Accept and highlight: Added header: Content-Encoding: deflate
2203 - Accept and highlight: Compressed content from 29258 to 8630 bytes.
2204 - Accept and highlight: Client request arrived in time on socket 21.
2205 - Highlight: Didn't receive data in time: a.fsdn.com:443
2206 - Accept log messages with ISO 8601 time stamps, too.
2209 - Bump generated Firefox version to 8.0.
2210 - Only randomize the release date if the new --randomize-release-date
2211 option is enabled. Firefox versions after 4 use a fixed date string
2214 *** Version 3.0.17 Stable ***
2216 - Fixed last-chunk-detection for responses where the body was small
2217 enough to be read with the headers, causing Privoxy to wait for the
2218 end of the content until the server closed the connection or the
2219 request timed out. Reported by "Karsten" in #3028326.
2220 - Responses with status code 204 weren't properly detected as body-less
2221 like RFC2616 mandates. Like the previous bug, this caused Privoxy to
2222 wait for the end of the content until the server closed the connection
2223 or the request timed out. Fixes #3022042 and #3025553, reported by a
2224 user with no visible name. Most likely also fixes a bunch of other
2225 AJAX-related problem reports that got closed in the past due to
2226 insufficient information and lack of feedback.
2227 - Fixed an ACL bug that made it impossible to build a blacklist.
2228 Usually the ACL directives are used in a whitelist, which worked
2229 as expected, but blacklisting is still useful for public proxies
2230 where one only needs to deny known abusers access.
2231 - Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
2232 network. This should make debugging various parsing issues a lot easier.
2233 - The IPv6 code is enabled by default on Windows versions that support it.
2234 Patch submitted by oCameLo in #2942729.
2235 - In mingw32 versions, the user.filter file is reachable through the
2236 GUI, just like default.filter is. Feature request 3040263.
2237 - Added the configure option --enable-large-file-support to set a few
2238 defines that are required by platforms like GNU/Linux to support files
2239 larger then 2GB. Mainly interesting for users without proper logfile
2241 - Logging with "debug 16" no longer stops at the first nul byte which is
2242 pretty useless. Non-printable characters are replaced with their hex value
2243 so the result can't span multiple lines making parsing them harder then
2245 - Privoxy logs when reading an action, filter or trust file.
2246 - Fixed incorrect regression test markup which caused a test in
2247 3.0.16 to fail while Privoxy itself was working correctly.
2248 While Privoxy accepts hide-referer, too, the action name is actually
2249 hide-referrer which is also the name used one the final results page,
2250 where the test expected the alias.
2252 - CGI interface improvements:
2253 - In finish_http_response(), continue to add the 'Connection: close'
2254 header if the client connection will not be kept alive.
2255 Anonymously pointed out in #2987454.
2256 - Apostrophes in block messages no longer cause parse errors
2257 when the blocked page is viewed with JavaScript enabled.
2258 Reported by dg1727 in #3062296.
2259 - Fix a bunch of anchors that used underscores instead of dashes.
2260 - Allow to keep the client connection alive after crunching the previous request.
2261 Already opened server connections can be kept alive, too.
2262 - In cgi_show_url_info(), don't forget to prefix URLs that only contain
2263 http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott.
2264 - Show the 404 CGI page if cgi_send_user_manual() is called while
2265 local user manual delivery is disabled.
2267 - Action file improvements:
2268 - Enable user.filter by default. Suggested by David White in #3001830.
2269 - Block .sitestat.com/. Reported by johnd16 in #3002725.
2270 - Block .atemda.com/. Reported by johnd16 in #3002723.
2271 - Block js.adlink.net/. Reported by johnd16 in #3002720.
2272 - Block .analytics.yahoo.com/. Reported by johnd16 in #3002713.
2273 - Block sb.scorecardresearch.com, too. Reported by dg1727 in #2992652.
2274 - Fix problems noticed on Yahoo mail and news pages.
2275 - Remove the too broad yahoo section, only keeping the
2276 fast-redirects exception as discussed on ijbswa-devel@.
2277 - Don't block adesklets.sourceforge.net. Reported in #2974204.
2278 - Block chartbeat ping tracking. Reported in #2975895.
2279 - Tag CSS and image requests with cautious and medium settings, too.
2280 - Don't handle view.atdmt.com as image. It's used for click-throughs
2281 so users should be able to "go there anyway".
2282 Reported by Adam Piggott in #2975927.
2283 - Also let the refresh-tags filter remove invalid refresh tags where
2284 the 'url=' part is missing. Anonymously reported in #2986382.
2285 While at it, update the description to mention the fact that only
2286 refresh tags with refresh times above 9 seconds are covered.
2287 - javascript needs to be blocked with +handle-as-empty-document to
2288 work around Firefox bug 492459. So move .js blockers from
2289 +block{Might be a web-bug.} -handle-as-empty-document to
2290 +block{Might be a web-bug.} +handle-as-empty-document.
2291 - ijbswa-Feature Requests-3006719 - Block 160x578 Banners.
2292 - Block another omniture tracking domain.
2293 - Added a range-requests tagger.
2294 - Added two sections to get Flickr's Ajax interface working with
2295 default pre-settings. If you change the configuration to block
2296 cookies by default, you'll need additional exceptions.
2297 Reported by Mathias Homann in #3101419 and by Patrick on ijbswa-users@.
2299 - Documentation improvements:
2300 - Explicitly mention how to match all URLs.
2301 - Consistently recommend socks5 in the Tor FAQ entry and mention
2302 its advantage compared to socks4a. Reported by David in #2960129.
2303 - Slightly improve the explanation of why filtering may appear
2305 - Grammar fixes for the ACL section.
2306 - Fixed a link to the 'intercepting' entry and add another one.
2307 - Rename the 'Other' section to 'Mailing Lists' and reword it
2308 to make it clear that nobody is forced to use the trackers
2309 - Note that 'anonymously' posting on the trackers may not always
2311 - Suggest to enable debug 32768 when suspecting parsing problems.
2313 - Privoxy-Log-Parser improvements:
2314 - Gather statistics for ressources, methods, and HTTP versions
2316 - Also gather statistics for blocked and redirected requests.
2317 - Provide the percentage of keep-alive offers the client accepted.
2318 - Add a --url-statistics-threshold option.
2319 - Add a --host-statistics-threshold option to also gather
2320 statistics about how many request where made per host.
2321 - Fix a bug in handle_loglevel_header() where a 'scan: ' got lost.
2322 - Add a --shorten-thread-ids option to replace the thread id with
2324 - Accept and ignore: Looks like we got the last chunk together
2325 with the server headers. We better stop reading.
2326 - Accept and ignore: Continue hack in da house.
2327 - Accept and higlight: Rejecting connection from 10.0.0.2.
2328 Maximum number of connections reached.
2329 - Accept and highlight: Loading actions file: /usr/local/etc/privoxy/default.action
2330 - Accept and highlight: Loading filter file: /usr/local/etc/privoxy/default.filter
2331 - Accept and highlight: Killed all-caps Host header line: HOST: bestproxydb.com
2332 - Accept and highlight: Reducing expected bytes to 0. Marking
2333 the server socket tainted after throwing 4 bytes away.
2334 - Accept: Merged multiple header lines to: 'X-FORWARDED-PROTO: http X-HOST: 127.0.0.1'
2337 - Remove the next member from the client_state struct. Only the main
2338 thread needs access to all client states so give it its own struct.
2339 - Garbage-collect request_contains_null_bytes().
2340 - Ditch redundant code in unload_configfile().
2341 - Ditch LogGetURLUnderCursor() which doesn't seem to be used anywhere.
2342 - In write_socket(), remove the write-only variable write_len in
2343 an ifdef __OS2__ block. Spotted by cppcheck.
2344 - In connect_to(), don't declare the variable 'flags' on OS/2 where
2345 it isn't used. Spotted by cppcheck.
2346 - Limit the scope of various variables. Spotted by cppcheck.
2347 - In add_to_iob(), turn an interestingly looking for loop into a
2349 - Code cleanup in preparation for external filters.
2350 - In listen_loop(), mention the socket on which we accepted the
2351 connection, not just the source IP address.
2352 - In write_socket(), also log the socket we're writing to.
2353 - In log_error(), assert that escaped characters get logged
2354 completely or not at all.
2355 - In log_error(), assert that ival and sval have reasonable values.
2356 There's no reason not to abort() if they don't.
2357 - Remove an incorrect cgi_error_unknown() call in a
2358 cannot-happen-situation in send_crunch_response().
2359 - Clean up white-space in http_response definition and
2360 move the crunch_reason to the beginning.
2361 - Turn http_response.reason into an enum and rename it
2362 to http_response.crunch_reason.
2363 - Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686 GNU/Linux.
2364 - Fix white-space in a log message in remove_chunked_transfer_coding().
2365 While at it, add a note that the message doesn't seem to
2366 be entirely correct and should be improved later on.
2368 - GNUmakefile improvements:
2369 - Use $(SSH) instead of ssh, so one only needs to specify a username once.
2370 - Removed references to the action feedback thingy that hasn't been
2372 - Consistently use shell.sourceforge.net instead of shell.sf.net so
2373 one doesn't need to check server fingerprints twice.
2374 - Removed GNUisms in the webserver and webactions targets so they
2375 work with standard tar.
2377 *** Version 3.0.16 Stable ***
2379 - Added the config file option handle-as-empty-doc-returns-ok to
2380 work around Firefox bug #492459, which causes Firefox to hang
2381 if JavaScripts are blocked in certain situations. The option is
2382 enabled in the default config file.
2383 - Added the config file option default-server-timeout to control the
2384 assumed default server timeout. Since Privoxy no longer returns
2385 an error message for connection resets on reused client connections,
2386 assuming larger server timeout values appears to actually work
2387 pretty well as long as connections aren't shared.
2388 - Added optional support for FreeBSD's accf_http(9). Use the
2389 configure option --enable-accept-filter to enable it.
2390 - Added fancier Privoxy icons for win32. Contributed by Jeff H.
2391 - In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
2392 - Resolve localhost using whatever address family the operating
2393 system feels like. Previous betas would try to use IPv4 as this
2394 is what most users expect, but this didn't work reliably on
2396 - In the action lists on CGI pages, actions and their parameters are
2397 no longer separated with a space. The action file parser doesn't
2398 actually allow this and will throw an invalid syntax error if actions
2399 and parameters in the action files are separated. Not adding the
2400 spaces means copy and pasting CGI output into the action files works.
2401 - The default keep-alive timeout has been reduced to 5 seconds to work
2402 around hangs in clients that treat the proxy like any other host and
2403 stop allowing any new connections if the "maximum number of
2404 connections per host" is reached.
2405 - Several webbug URLs that look like they are leading to images are now
2406 blocked as image instead of empty documents. Doing the latter causes
2407 WebKit-based clients to show a "missing image" icon which may mess up
2409 - The no-such-domain template is used for DNS resolution
2410 problems with FEATURE_IPV6_SUPPORT enabled. Previously the
2411 connect-failed template was used. Reported by 'zebul666'.
2412 - Accepts quoted expiration dates even though RFC 2109 10.1.2
2413 doesn't seem to allow them. Reported anonymously.
2414 - Don't try to forget connections if connection sharing is disabled.
2415 This wasn't a real problem but caused an unnecessary log message.
2416 - The still undocumented --enable-extended-host-patterns configure
2417 option has a better description.
2418 - Fixed an error message that would claim a write to the server
2419 failed when actually writing to the client failed.
2420 - Log the crunch reason before trying to write to the client.
2421 The log is easier to read that way.
2422 - Several log messages about client connections also mention
2424 - handle-as-empty-document no longer depends on the image blocking
2426 - Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
2427 - uagen, a Firefox User-Agent generator for Privoxy and Mozilla
2428 browsers has been imported and is available in the tarball's
2430 - The scripts in the tools directory treat unknown parameters
2433 *** Version 3.0.15 beta ***
2435 - In case of missing server data, no error message is send to the
2436 client if the request arrived on a reused connection. The client
2437 is then supposed to silently retry the request without bothering
2438 the user. This should significantly reduce the frequency of the
2439 "No server or forwarder data received" error message many users
2441 - More reliable detection of prematurely closed client sockets
2442 with keep-alive enabled.
2443 - FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
2444 FEATURE_CONNECTION_SHARING and now available on
2446 - Improved handling of POST requests on reused connections.
2447 Should fix problems with stalled connections after submitting
2448 form data with some browser configurations.
2449 - Fixed various latency calculation issues.
2450 - Allows the client to pass NTLM authentication requests to a
2451 forwarding proxy. This was already assumed and hinted to work
2452 in 3.0.13 beta but actually didn't. Now it's confirmed to work
2453 with IE, Firefox and Chrome.
2454 Thanks to Francois Botha and Wan-Teh Chang
2455 - Fixed a calculation problem if receiving the server headers
2456 takes more than two reads, that could cause Privoxy to terminate
2457 the connection prematurely. Reported by Oliver.
2458 - Compiles again on platforms such as OpenBSD and systems
2459 using earlier glibc version that don't support AI_ADDRCONFIG.
2460 Anonymously submitted in #2872591.
2461 - A bunch of MS VC project files and Suse and Redhat RPM spec
2462 files have been removed as they were no longer maintained for
2464 - Overly long action lines are properly rejected with a proper
2465 error message. Previously they would be either rejected as
2466 invalid or cause a core dump through abort().
2467 - Already timed-out connections are no longer temporarily remembered.
2468 They weren't reused anyway, but wasted a socket slot.
2469 - len refers to the number of bytes actually read which might
2470 differ from the ones received. Adjust log messages accordingly.
2471 - The optional JavaScript on the CGI page uses encodeURIComponent()
2472 instead of escape() which doesn't encode all characters that matter.
2473 Anonymously reported in #2832722.
2474 - Fix gcc45 warnings in decompress_iob().
2475 - Various log message improvements.
2476 - Privoxy-Regression-Test supports redirect tests.
2477 - Privoxy-Log-Parser can gather some connection statistics.
2479 *** Version 3.0.14 beta ***
2481 - The latency is taken into account when evaluating whether or not to
2482 reuse a connection. This should significantly reduce the number of
2483 connections problems several users reported.
2484 - If the server doesn't specify how long the connection stays alive,
2485 Privoxy errs on the safe side of caution and assumes it's only a second.
2486 - The error pages for connection timeouts or missing server data use a
2487 Last-Modified date in the past. Retry attempts are detected and Privoxy
2488 removes the If-Modified-Since header to prevent the server from responding
2489 with status code 304 in which case the client would reuse the error message.
2490 - Setting keep-alive-timeout to 0 disables keep-alive support. Previously
2491 Privoxy would claim to allow persistence but not reuse the connection.
2492 - Pipelined requests are less likely to be mistaken for the request
2493 body of the previous request. Note that Privoxy still has no real
2494 pipeline support and will either serialize pipelined requests or
2495 drop them in which case the client has to resent them.
2496 - Fixed a crash on some Windows versions when header randomization
2497 is enabled and the date couldn't be parsed.
2498 - Privoxy's keep-alive timeout for the current connection is reduced
2499 to the one specified in the client's Keep-Alive header.
2500 - For HTTP/1.1 requests, Privoxy implies keep-alive support by not
2501 setting any Connection header instead of using 'Connection: keep-alive'.
2502 - If the socket isn't reusable, Privoxy doesn't temporarily waste
2503 a socket slot to remember the connection.
2504 - If keep-alive support is disabled but compiled in, the client's
2505 Keep-Alive header is removed.
2506 - Fixed a bug on mingw32 where downloading large files failed if
2507 keep-alive support was enabled.
2508 - Fixed a bug that (at least theoretically) could cause log
2509 timestamps to be occasionally off by about a second.
2510 - No Proxy-Connection header if added if there already is one.
2511 - The configure script respects the $PATH variable when searching
2514 *** Version 3.0.13 beta ***
2516 - Added IPv6 support. Thanks to Petr Pisar who not only provided
2517 the initial patch but also helped a lot with the integration.
2518 - Added client-side keep-alive support.
2519 - The connection sharing code is only used if the connection-sharing
2521 - The max-client-connections option has been added to restrict
2522 the number of client connections below a value enforced by
2523 the operating system.
2524 - Fixed a regression reintroduced in 3.0.12 that could cause
2525 crashes on mingw32 if header date randomization was enabled.
2526 - Compressed content with extra fields couldn't be decompressed
2527 and would get passed to the client unfiltered. This problem
2528 has only be detected through statical analysis with clang as
2529 nobody seems to be using extra fields anyway.
2530 - If the server resets the Connection after sending only the headers
2531 Privoxy forwards what it got to the client. Previously Privoxy
2532 would deliver an error message instead.
2533 - Error messages in case of connection timeouts use the right
2535 - If spawning a child to handle a request fails, the client
2536 gets an error message and Privoxy continues to listen for
2537 new requests right away.
2538 - The error messages in case of server-connection timeouts or
2539 prematurely closed server connections are now template-based.
2540 - If zlib support isn't compiled in, Privoxy no longer tries to
2541 filter compressed content unless explicitly asked to do so.
2542 - In case of connections that are denied based on ACL directives,
2543 the memory used for the client IP is no longer leaked.
2544 - Fixed another small memory leak if the client request times out
2545 while waiting for client headers other than the request line.
2546 - The client socket is kept open until the server socket has
2547 been marked as unused. This should increase the chances that
2548 the still-open connection will be reused for the client's next
2549 request to the same destination. Note that this only matters
2550 if connection-sharing is enabled.
2551 - A TODO list has been added to the source tarball to give potential
2552 volunteers a better idea of what the current goals are. Donations
2553 are still welcome too: https://www.privoxy.org/faq/general.html#DONATE
2555 *** Version 3.0.12 ***
2557 - The socket-timeout option now also works on platforms whose
2558 select() implementation modifies the timeout structure.
2559 Previously the timeout was triggered even if the connection
2560 didn't stall. Reported by cyberpatrol.
2561 - The Connection: keep-alive code properly deals with files
2562 larger than 2GB. Previously the connection was closed too
2564 - The content length for files above 2GB is logged correctly.
2565 - The user-manual directive on the show-status page links to
2566 the documentation location specified with the directive,
2567 not to the Privoxy website.
2568 - When running in daemon mode, Privoxy doesn't log anything
2569 to the console unless there are errors before the logfile
2571 - The show-status page prints warnings about invalid directives
2572 on the same line as the directives themselves.
2573 - Fixed several justified (but harmless) compiler warnings,
2574 mostly on 64 bit platforms.
2575 - The mingw32 version explicitly requests the default charset
2576 to prevent display problems with some fonts available on more
2577 recent Windows versions. Patch by Burberry.
2578 - The mingw32 version uses the Privoxy icon in the alt-tab
2579 windows. Patch by Burberry.
2580 - The timestamp and the thread id is omitted in the "Fatal error"
2581 message box on mingw32.
2582 - Fixed two related mingw32-only buffer overflows. Triggering
2583 them required control over the configuration file, therefore
2584 this isn't seen as a security issue.
2585 - In verbose mode, or if the new option --show-skipped-tests
2586 is used, Privoxy-Regression-Test logs skipped tests and the
2589 *** Version 3.0.11 ***
2591 - On most platforms, outgoing connections can be kept alive and
2592 reused if the server supports it. Whether or not this improves
2593 things depends on the connection.
2594 - When dropping privileges, membership in supplementary groups
2595 is given up as well. Not doing that can lead to Privoxy running
2596 with more rights than necessary and violates the principle of
2597 least privilege. Users of the --user option are advised to update.
2598 Thanks to Matthias Drochner for reporting the problem,
2599 providing the initial patch and testing the final version.
2600 - Passing invalid users or groups with the --user option
2601 didn't lead to program exit. Regression introduced in 3.0.7.
2602 - The match all section has been moved from default.action
2603 to a new file called match-all.action. As a result the
2604 default.action no longer needs to be touched by the user
2605 and can be safely overwritten by updates.
2606 - The standard.action file has been removed. Its content
2607 is now part of the default.action file.
2608 - In some situations the logged content length was slightly too low.
2609 - Crunched requests are logged with their own log level.
2610 If you used "debug 1" in the past, you'll probably want
2611 to additionally enable "debug 1024", otherwise only passed
2612 requests will be logged. If you only care about crunched
2613 requests, simply replace "debug 1" with "debug 1024".
2614 - The crunch reason has been moved to the beginning of the
2615 crunch message. For HTTP URLs, the protocol is logged as well.
2616 - Log messages are shortened by printing the thread id on its
2617 own (as opposed to putting it inside the string "Privoxy()").
2618 - The config option socket-timeout has been added to control
2619 the time Privoxy waits for data to arrive on a socket.
2620 - Support for remote toggling is controlled by the configure
2621 option --disable-toggle only. In previous versions it also
2622 depended on the action editor and thus configuring with the
2623 --disable-editor option would disable remote toggling support
2625 - Requests with invalid HTTP versions are rejected.
2626 - The template symbol @date@ can be used to include a date(1)-like
2627 time string. Initial patch submitted by Endre Szabo.
2628 - Responses from shoutcast servers are accepted again.
2629 Problem reported and fix suggested by Stefan.
2630 - The hide-forwarded-for-headers action has been replaced with
2631 the change-x-forwarded-for{} action which can also be used to
2632 add X-Forwarded-For headers. The latter functionality already
2633 existed in Privoxy versions prior to 3.0.7 but has been removed
2634 as it was often used unintentionally (by not using the
2635 hide-forwarded-for-headers action).
2636 - A "clear log" view option was added to the mingw32 version
2637 to clear out all of the lines in the Privoxy log window.
2638 Based on a patch submitted by T Ford.
2639 - The mingw32 version uses "critical sections" now, which prevents
2640 log message corruption under load. As a side effect, the
2641 "no thread-safe PRNG" warning could be removed as well.
2642 - The mingw32 version's task bar icon is crossed out and
2643 the color changed to gray if Privoxy is toggled off.
2645 *** Version 3.0.10 ***
2647 - Ordinary configuration file changes no longer cause program
2648 termination on OS/2 if the name of the logfile hasn't been
2649 changed as well. This regression probably crept in with the
2650 logging improvements in 3.0.7. Reported by Maynard.
2651 - The img-reorder filter is less likely to mess up JavaScript code in
2652 img tags. Problem and solution reported by Glenn Washburn in #2014552.
2653 - The source tar ball now includes Privoxy-Log-Parser,
2654 a syntax-highlighter for Privoxy logs. For fancy screenshots see:
2655 http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
2656 Documentation is available through perldoc(1).
2658 *** Version 3.0.9 beta ***
2660 - Added SOCKS5 support (with address resolution done by
2661 the SOCKS5 server). Patch provided by Eric M. Hopper.
2662 - The "blocked" CGI pages include a block reason that was
2663 provided as argument to the last-applying block action.
2664 - If enable-edit-actions is disabled (the default since 3.0.7 beta)
2665 the show-status page hides the edit buttons and explains why.
2666 Previously the user would get the "this feature has been disabled"
2667 message after using the edit button.
2668 - Forbidden CONNECT requests are treated like blocks by default.
2669 The now-pointless treat-forbidden-connects-like-blocks action
2671 - Not enabling limit-connect now allows CONNECT requests to all ports.
2672 In previous versions it would only allow CONNECT requests to port 443.
2673 Use +limit-connect{443} if you think you need the old default behaviour.
2674 - The CGI editor gets turned off after three edit requests with invalid
2675 file modification timestamps. This makes life harder for attackers
2676 who can leverage browser bugs to send fake Referers and intend to
2677 brute-force edit URLs.
2678 - Action settings for multiple patterns in the same section are
2679 shared in memory. As a result these sections take up less space
2680 (and are loaded slightly faster). Problem reported by Franz Schwartau.
2681 - Linear white space in HTTP headers will be normalized to single
2682 spaces before parsing the header's content, headers split across
2683 multiple lines get merged first. This should prevent problems like:
2684 * letting the session-cookies-only action slip
2685 some Cookies through unmodified,
2686 * only suppressing the first line of a header,
2687 thus creating an invalid one, and
2688 * to incorrectly block headers with valid timestamps
2689 that weren't properly recognized.
2690 Headers that could trigger these problems are unlikely to appear
2691 in "normal" web traffic, but could be intentionally generated to
2692 fool some of Privoxy's header parsers.
2693 - Host information is gathered outside the main thread so it's less
2694 likely to delay other incoming connections if the host is misconfigured.
2695 - New config option "hostname" to use a hostname other than
2696 the one returned by the operating system. Useful to speed-up responses
2697 for CGI requests on misconfigured systems. Requested by Max Khon.
2698 - The CGI editor supports the "disable all filters of this type"
2699 directives "-client-header-filter", "-server-header-filter",
2700 "-client-header-tagger" and "-server-header-tagger".
2701 - Fixed false-positives with the link-by-url filter and URLs that
2702 contain the pattern "/jump/".
2703 - The less-download-windows filter no longer messes
2704 "Content-Type: application/x-shockwave-flash" headers up.
2705 - In the show-url-info page's "Final results" section active and
2706 inactive actions are listed separately. Patch provided by Lee.
2707 - The GNUmakefile supports the DESTDIR variable. Patch for
2708 the install target submitted by Radoslaw Zielinski.
2709 - Embedding the content of configuration files in the show-status
2710 page is significantly faster now. For a largish action file (1 MB)
2711 a speedup of about 2450 times has been measured. This is mostly
2712 interesting if you are using large action files or regularly use
2713 Privoxy-Regression-Test while running Privoxy through Valgrind,
2714 for stock configuration files it doesn't really matter.
2715 - If zlib support is unavailable and there are content
2716 filters active but the prevent-compression action is disabled,
2717 the show-url-info page includes a warning that compression
2718 might prevent filtering.
2719 - The show-url-info page provides an OpenSearch Description that
2720 allows to access the page through browser search plugins.
2721 - Custom client-header filters that rewrite the request line
2722 incorrectly no longer cause Privoxy to crash. Reported by din_a4.
2723 - The obsolete kill-popups action has been removed as the
2724 PCRS-based popup filters can do the same and are slightly
2726 - The inspect-jpegs action has been removed.
2727 - The send-wafer and send-vanilla-wafer actions have been removed.
2728 They weren't particular useful and their behaviour could be emulated
2729 with add-header anyway.
2730 - Privoxy-Regression-Test has been significantly improved.
2731 - Most sections in the default.action file contain tests for
2732 Privoxy-Regression-Test to verify that they are working as intended.
2733 - Parts of Privoxy have been refactored to increase maintainability.
2734 - Building with zlib (if available) is done by default.
2736 *** Version 3.0.8 ***
2738 - Fixed a small memory leak when listen-address only specifies the port.
2739 - The source tar balls now include Privoxy-Regression-Test which
2740 (upon other things) can be used to automatically detect some
2741 packaging problems. Packagers are welcome to give it a try.
2742 - Reverted a change in 3.0.7 that caused path patterns to be checked
2743 even if the host pattern match already failed. While this doesn't
2744 noticeable affect the performance, it makes it less likely to run
2745 out of stack space with overly-complex path patterns the user might
2747 - Updated the msn, yahoo and google filters to work as advertised again.
2748 - The warning message shown by the show-status CGI page is easier to
2749 understand. Previously it wasn't clear that the error message
2750 is shown below the invalid directive. (Reported by Lee)
2751 - When regenerating Content-Disposition headers the more common
2752 spelling is used for the name. Previously it was written without caps.
2753 - Less confusing log message if the content type isn't overwritten
2754 because force-text-type wasn't used but the old type doesn't look
2755 like content that would be filtered normally.
2756 - Better log messages if the user tries to execute filters that
2758 - Treat the non-standard Request-Range headers like standard range
2759 headers and suppress them if content filtering is enabled.
2760 - Prevent the log messages for CONNECT requests to unacceptable
2761 ports from printing the limit-connect argument as [null] if
2762 limit-connect hasn't been explicitly enabled.
2763 - Don't disable the mingw32 log window if the logfile directive
2764 isn't used. While it was an intentional change in 3.0.7 at least
2765 one user perceived it as a regression and the same effect can
2766 be achieved by disabling all debug directives.
2767 - Fixed two minor problems related to the win32 build process: a css
2768 file was not being in the installer and the trustfile comment in the
2769 config.txt referenced a nonexisting file
2770 - Minor documentation fixes.
2772 *** Version 3.0.7 beta ***
2774 - Added zlib support to filter content with gzip and deflate
2775 encoding. (Patch provided by Wil Mahan)
2776 - Dedicated filters and actions are used for header filtering.
2777 "filter-client-headers" and "filter-client-headers" are no longer
2778 supported, use server-header-filter{} and client-header-filter{}
2780 - Tags can be used to change actions based on HTTP headers.
2781 - New server-header filter: less-download-windows.
2782 - New client-header taggers: css-requests, image-requests,
2783 client-ip-address, http-method, allow-post, complete-url,
2784 user-agent and privoxy-control.
2785 - New server-header taggers: content-type and privoxy-control.
2786 - The forward-override{} action allows to change the forwarding
2787 settings through the action files, for example based on client
2788 headers like the User-Agent, or the request origin.
2789 - Socks errors are no longer handled by the CGI page for
2790 DNS resolution failures.
2791 - CGI pages use favicons to signal whether they are error
2792 or control pages. This is useful if you rely heavily on
2794 - The show-url-info CGI page shows the forwarding settings.
2795 - "Crunch!" log messages (used when Privoxy answers requests
2796 by itself) now also contain the reason.
2797 - Allow to rewrite the request destination behind the client's back.
2798 - Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
2799 - Fixes possible deadlocks and crashes on OpenBSD.
2800 Patch provided by Ralf Horstmann.
2801 - The CGI action editor allows to edit actionfiles with previously
2802 forbidden characters like dots.
2803 - New trust entries are saved with a comment that contains the
2804 trusted referring URL (Suggested by Daniel Griscom).
2805 - Filter descriptions are HTML encoded automatically.
2806 - New config option "split-large-forms" to work
2807 around a browser bug that caused IE6 and IE7 to ignore
2808 the Submit button on the edit-actions-for-url CGI page.
2809 - New config option "allow-cgi-request-crunching" to allow
2810 requests for Privoxy's CGI pages to be blocked, redirected
2811 or (un)trusted like ordinary requests.
2812 - Empty filter files no longer interrupt the filtering process
2813 prematurely and are correctly listed on the show-status CGI page.
2814 - New config option "accept-intercepted-requests" to combine
2815 Privoxy with any packet filter to build an intercepting proxy
2816 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
2817 - fast-redirects{} catch redirects to https URLs as well.
2818 - redirect{s@foo@bar@} can be used to redirect to a rewritten
2819 version of the original URL.
2820 - Trap unsupported gopher proxy requests.
2821 - Fixed a bug in the User Manual delivery on Windows
2822 (mingw32 only). Images now show up correctly and HTML
2823 pages are no longer padded with garbage data.
2824 - Fixed several minor memory leaks, most of them discovered with Valgrind.
2825 - Only unlink the pidfile if it's actually used.
2826 - Retries after connection problems with forced requests
2827 aren't blocked again.
2828 - On Unix SIGABRT causes a core dump as expected and is no
2829 longer treated as normal shutdown signal.
2830 - The "access denied" CGI page is more descriptive and
2831 allows retries to circumvent the referrer check.
2832 - Updated PCRS to handle unexpected PCRE errors properly.
2833 Fixed crashes that could occur if Privoxy was build
2834 with external PCRE versions newer than Privoxy's internal
2835 one. (Reported by Chung-chieh Shan)
2836 - Fixed crashes with null bytes in PCRS replacement strings
2837 (Patch provided by Felix Gröbert).
2838 - Fixed crashes with header time randomization on mingw32.
2839 - The CGI style sheet is no longer delivered if the referring
2840 page isn't a Privoxy CGI page. This prevents a JavaScript-based
2841 Privoxy detection "attack". Note that detecting Privoxy is
2842 still possible through other ways and Privoxy was never intended
2843 to be invisible anyway.
2844 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
2845 - The show-url-info CGI page displays a warning if Privoxy
2846 is currently toggled off.
2847 - The show-status CGI page suppresses the edit button
2848 for action files if Privoxy has no write access.
2849 - Most CGI error pages react properly to HEAD requests.
2850 - Requests with RFC 3253 HTTP methods (used by Subversion)
2851 are accepted. (Patch provided by Petr Kadlec)
2852 - New config option "templdir" to change the location
2853 of the CGI templates to make sure customized templates
2855 - Better handling of "HTTP/1.1 100 Continue" responses.
2856 - The background of the PNG pattern is transparent.
2857 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
2858 - Fixed crashes and possible action file corruptions
2859 when lines containing hashes are written through the CGI editor.
2860 - Supports dynamic filters which can contain variables.
2861 - Supports tags to change the actions based on client or server headers.
2862 - Incorrect actions are logged before program termination.
2863 - The "actionsfile" syntax in the configuration file is consistent
2864 with the rest of the configuration options and requires the
2865 whole file name. This is an incompatible change, if you use
2866 an old configuration file you might have to append ".action"
2867 to your "actionsfile" directives.
2868 - With the configuration file option "enforce-blocks" the
2869 "go there anyway" mechanism can be disabled without recompiling
2871 - More precise error messages in case of incorrect acl syntax.
2872 - Logs a warning if filtering is enabled but impossible due
2873 to lack of zlib support or use of the prevent-compression action.
2874 - Less noisy handling of Cookie:" and "Connection:" headers.
2875 - Improved error messages in case of connection problems.
2876 - Fix a command-line-parsing bug that was introduced before 3.0.5
2877 beta and caused Privoxy to treat the last argument as configuration
2878 file if no configuration file was specified.
2879 - Treat unknown command line options as fatal errors instead
2880 of silently ignoring them.
2881 - Use string functions with length checks more often.
2882 - Don't log CONNECT requests twice.
2883 - Allow to log the source address for ACL-related connection drops.
2884 - Don't ignore applying filters if the server didn't
2885 specify a Content-Type. Bug reported by Amuro Namie.
2886 - Rejected CONNECT requests are logged with log level info
2887 (enabled by default) and the reason for the block.
2888 - New command line option "--pre-chroot-nslookup hostname" to
2889 intialize the resolver library before chroot'ing. On some systems this
2890 reduces the number of files that must be copied into the chroot tree.
2891 (Patch provided by Stephen Gildea)
2892 - Fix a long-standing memory corruption bug that could cause
2893 Privoxy to overwrite a single byte in memory it didn't explicitly
2894 allocate (but that probably was allocated anyway due to bucket size).
2895 - Send template-based CGI pages as HTTP/1.1 unless the client
2897 - Let the first line in connection established responses
2898 end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
2899 - If no log file has been specified, disable logging instead of logging
2901 - Don't block stderr when in daemon mode.
2902 - Ignore missing zero-chunks when filtering chunk-encoded content.
2903 Earlier Privoxy versions would buffer and then forward the content
2904 unmodified which caused some browsers to simply show empty pages.
2905 - Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
2906 - The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
2907 action isn't being used has been removed.
2908 - Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
2910 - Minor code clean-ups, filter and action file updates.
2911 (Some of them reported by Davide Alberani, Markus Elfring,
2912 Stefan Huehner and Adam Piggott)
2914 *** Version 3.0.6 ***
2916 - New content filters: no-ping, google, msn, yahoo and blogspot.
2917 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
2918 and hide-tor-exit-notation.
2919 - The special header "X-Filter: No" now disables header filtering as well.
2920 - Improved the filters img-reorder, js-annoyances, webbugs,
2921 banners-by-size, banners-by-link and ie-exploits to make them
2922 less likely to break anything.
2923 - Removed outdated URL patterns in default.action and added new ones.
2924 - Added redirection from http://p.p/user-manual to http://p.p/user-manual/
2925 - Changed webinterface default values for hide-user-agent, hide-referrer
2926 and set-image-blocker.
2928 *** Version 3.0.5 beta ***
2930 - Windows version can be installed/started as a service.
2931 - Windows icon stays blue when Privoxy is idle, green when busy.
2932 - Integrated Fabian Keil's extensive patch. See:
2933 http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
2934 following new or significantly improved actions (among many
2935 other improvements):
2937 content-type-overwrite{}
2938 crunch-client-header{string}
2939 crunch-if-none-match
2940 crunch-server-header{string}
2941 fast-redirects{check-decoded-url}
2942 filter-client-headers
2943 filter-server-headers
2945 handle-as-empty-document
2946 hide-accept-language{}
2947 hide-content-disposition{}
2948 hide-if-modified-since
2949 hide-referrer{conditional-block}
2950 overwrite-last-modified{}
2952 treat-forbidden-connects-like-blocks
2954 - Standard-compliant clients are prevented from displaying cached
2955 copies of Privoxy's error messages after the cause of the problem
2957 - Improved DNS error handling.
2958 - Multiple filter files can now be specified in config.
2959 - Added jpeg filtering to defend against MS jpeg vulnerability MS04-028
2960 with the new inspect-jpegs action.

2975 *** Version 3.0.3 ***
2977 - Fixed yet another two memory leaks. Process growth seems stopped now.
2978 - Further tightened security against malicious toggle-off links.
2979 - Excluded text/plain MIME types from filtering. This fixes a
2980 couple of client-crashing, download corruption and
2981 Privoxy performance issues, whose root cause lies in
2982 web servers labelling content of unknown type as text/plain.
2983 - Assorted fixes for POSIX compliance, signal handling, graceful
2984 termination, compiler warnings, OSX support, Win32 systray,
2985 error logging, hostname wildcards, correct detection of NetBSD.
2986 - Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs
2987 including the notorious "blank page" problem.

2999 - Added workaround for Bug in Mac OSX that made Privoxy crash occasionally
3000 - Refined the default action file through >400 items of user feedback
3002 - Assorted refinements, optimizations and fixes in the js-annoyances,
3003 img-reorder, banners-by-size, banners-by-link, webbugs, refresh-tags,
3004 html-annoyances, content-cookies and fun filters
3005 - Replaced filter "popups" by choice between two modes:
3006 - "unsolicited-popups" tries to catch only the unsolicited ones
3007 - "all-popups" tries to kill them all (as before)
3008 - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
3009 - New filter "jumping-windows" that prevents windows from resizing
3010 and moving themselves
3011 - New filter "demoronizer" which fixes MS's abuse of std charsets
3012 (common cases anyway).
3013 - Replaced "nimda" with more general "ie-exploits" filter in which
3014 all filters for exploits shall be collected
3015 - Improved cookie logging
3016 - Rewrote make install target. Added uninstall and install-strip
3018 - Fixed a potential (application-level, NOT OS-level!) security
3019 problem involving remote toggling and action file manipulation
3020 by mailicious websites.
3021 - Added ability to chroot (thanks to Sviatoslav Sviridov)
3022 - Added more action aliases for prehistoric action names

3042 *** Version 2.9.16 ***
3044 - Major revamp of default.action to get rid of years of cruft.
3045 - Same for default.filter
3046 - Re-design and major improvements to the CGI editor interface.

3067 problems via web interface at privoxy.org. Accessed via internal CGIs.
3068 - Include cgi-style.css for templates.
3069 - #include mechansim for common text in templates
3070 - Various other minor fixes.
3072 *** Version 2.9.13 beta ***
3074 - *NEWS*: The project has been renamed to Privoxy! The new name is
3075 reflected throughout (file locations, etc).
3076 - ijb.action is now default.action. re_filterfile is now
3078 - http://i.j.b/ is now http://p.p/

3106 - Fix restart failure where sockets were in TIME_WAIT.
3107 - Fixes for actions cgi editor, make sure we have right file.
3108 - A --pidfile command line option now, in addition to --help,
3109 --version, --no-daemon, --user and configfile. --no-daemon replaces

3146 - Many other minor bugfixes
3147 - Start a ChangeLog :)
3151 *** Version 2.9.3 pre-Alpha Changes ***
3153 - Amiga support (completely untested by me - I don't have an Amiga)
3154 - "tinygif 3" support (redirects blocked images to a specified URL, so
3155 the browser doesn't have to load and cache many copies of the same
3157 - one case where there were both local and global "referrer" variables
3158 (yuck!) clarified by renaming the local one to "refer".
3159 - Fixed some places where close() was used instead of close_socket().
3160 Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
3161 - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
3162 FORCE_LOAD_PREFIX. Needs fixing properly.
3163 - Most URLs hardcoded into Junkbuster were changed to go through a script
3164 e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
3165 The only other URLs left are the GNU GPL:
3166 http://www.fsf.org/copyleft/gpl.html
3168 http://ijbswa.sourceforge.net/
3169 ... and various URLs which will be intercepted by Junkbuster anyway.
3170 TODO: Still need to do something with the URLs in Junkbuster Corp's
3171 copyright/trademark notice on the bottom of the show-proxy-args page.
3172 - PCRE or GNU Regex is now a #define option.
3175 *** Version 2.9.2 pre-Alpha Changes ***
3177 - Andreas applied the latest version of the FORCE patch.
3180 *** Version 2.9.1 pre-Alpha Changes ***
3182 - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
3183 (BTW: I think FORCE is precise enough, since loading remote
3184 data is the whole purpose of a proxy..)
3185 - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
3186 is more elegant and looks like a hostname in the URL, it doesn't
3187 make clear to the inexperienced user that the proxy is bypassed. It
3188 also has a higher name collision risk.
3189 - Filled in the function header templates for my functions in
3190 parsers.c (again). They obviously got lost in our current
3192 - Cut the credit for the §-referrer-option from the config file,
3193 that Stefan had placed there.
3194 - Improved the re_filterfile
3197 *** Version 2.9.0 pre-Alpha Changes ***
3199 - Now use PCRE, not GNU REGEX. I have not yet had chance to check the
3200 syntax of the block/image/cookie file to ensure that they match what
3201 is expected - however they seem to work.
3202 - Replaced "configure" script with one generated by "autoconf". Also
3203 use a header "config.h" (was ijbconfig.h in my previous release) for
3204 the #defines. "config.h" is now generated with "autoheader" from
3205 "acconfig.h" and "configure.in". (Note that to install you do not
3206 need autoconf or autoheader - just run "./configure".)
3207 To see command-line options, run "./configure --help".
3208 This is my first ever autoconf script, so it has some rough edges
3209 (how PCRE is handled is the roughest).
3210 - Error logging code replaced with new module errlog.c, based on the
3211 one from JunkbusterMT (but with the threading code removed).
3212 - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
3213 apply all of these, since I had already independently done conditional
3214 popup file, conditional image file, and integration of popup code.
3215 - ACL, Jar and trust files conditionally compiled.
3216 - New source file headers.
3217 - Various cosmetic changes. (But I have not consistently ordered the
3218 config files - I think that's worthwhile, but it's 1am and I want to
3220 - RCS tags on .h files.
3221 - RCS tags are const char[] rather than const char *. (Saves 4 bytes
3223 - VC++ project files renamed to vc_junkbuster.*.
3224 - show-proxy-args now shows status of all conditionals, not just REGEX
3225 - Various functions moved around. Most notably all the system-specific
3226 sockets code which was spread between jcc.c, bind.c, and connect.c,
3227 has been moved to "jbsockets.c". The non-system-specific code from
3228 connect.c and socks4.c has been movet to "gateway.c". Also, the
3229 config file loader and the global variables it writes to have been
3230 moved to "loadcfg.c". (Maybe this should go into loaders.c?)
3231 And candidate for the "worst filename ever" award is "miscutil.c",
3232 which contains, well, miscellaneous utility functions like zalloc.
3233 (Suggestions for a better name for this file are welcome!)
3234 - Loaders now use a common function to read a line and skip comments,
3235 and this function also stores the proxy_args.
3236 - Added ./junkbuster --help (Not for Win32 GUI)
3237 - Added ./junkbuster --version (Not for Win32 GUI)
3238 - Win32 resources are now all marked as "U.S. English", rather than
3239 being a mix of "U.S. English", "U.K. English" and "Irish English".
3240 - Version number changes to 2.9.0
