22 - Fixed a memory leak if multiple filters are executed
23 and the last one is skipped due to a pcre error.
24 Commit 5cfb7bc8fe. OVE-20201118-0005.
25 - Prevent an unlikely dereference of a NULL-pointer that
26 could result in a crash if accept-intercepted-requests
27 was enabled, Privoxy failed to get the request destination
28 from the Host header and a memory allocation failed.
29 Commit 7530132349. CID 267165. OVE-20201118-0006.
30 - Fixed memory leaks in the client-tags CGI handler when
31 client tags are configured and memory allocations fail.
32 Commit cf5640eb2a. CID 267168. OVE-20201118-0007.
33 - Fixed memory leaks in the show-status CGI handler when memory
34 allocations fail. Commit 064eac5fd0 and commit fdee85c0bf3.
35 CID 305233. OVE-20201118-0008.
37 - General improvements:
38 - Added experimental https inspection support which allows to filter
39 https traffic. To enable it, install MbedTLS and configure with
40 --with-mbedtls, or install OpenSSL or LibreSSL and configure
42 Afterwards configure the directives in section 7 of the
43 config file and enable the +https-inspection action.
44 Initial MbedTLS-based code contributed by Vaclav Svec,
45 initial OpenSSL support contributed by Maxim Antonov.
46 With help from Nedzad Hrnjica and Ho+ Ho+ Ho+.
47 Integration and improvements sponsored by Robert Klemme.
48 - pcrs: Request JIT compilation if it's supported and
49 the filter isn't dynamic. This can speed up filtering.
50 - Added support for Brotli decompression.
51 Sponsored by: Robert Klemme
52 - Added FEATURE_EXTENDED_STATISTICS to gather statistics for
53 block reasons and filter executions. To enable it, configure
54 with --enable-extended-statistics and visit
55 http://config.privoxy.org/show-status.
56 Sponsored by: Robert Klemme
57 - Use the IP_FREEBIND socket option, if defined. This allows
58 Privoxy to bind to not-yet assigned IP addresses which is
59 useful in failover environments.
60 Patch by Sam Varshavchik.
61 - Allow to use extended host patterns and vanilla host patterns
62 at the same time by prefixing extended host patterns with
63 "PCRE-HOST-PATTERN:". To enable this, configure with
64 --enable-pcre-host-patterns.
65 Sponsored by: Robert Klemme
66 - Added "Cross-origin resource sharing" (CORS) support.
67 This allows to access Privoxy's CGI interface via JavaScript from
68 another domain (white-listed with the new cors-allowed-origin directive).
69 Based on a patch by Nedzad Hrnjica.
70 Sponsored by: Robert Klemme.
71 - Add SOCKS5 username/password support.
72 Based on a patch by Sam, improved by Ivan Romanov.
73 Closes Patch#141 and solves TODO#105.
74 - Bump the maximum number of action and filter files
76 Sponsored by: Robert Klemme
77 - Fixed handling of filters with "split-large-forms 1"
78 when using the CGI editor.
79 Reported by withoutname in #921.
80 - Better detect a mismatch of connection details when
81 figuring out whether or not a connection can be reused.
82 - Don't send a "Connection failure" message instead of the
83 "DNS failure" message.
84 Sponsored by: Robert Klemme
85 - Let LOG_LEVEL_REQUEST log all requests. Previously unencrypted
86 requests were only logged with LOG_LEVEL_REQUEST when they weren't
87 crunched (in which case they were logged with LOG_LEVEL_CRUNCH).
88 This was documented behaviour, but logging all requests seems more useful.
89 - Fixed locking around localtime() and gmtime().
90 - Removed OS/2 support. We haven't provided OS/2 packages in years,
91 it complicated the code and it depended on a fallback snprintf()
92 implementation which is GPLv2 only.
93 - Remove the fallback snprintf() implementation
94 Now that OS/2 support is gone we no longer need it.
95 - Fixed a bunch of format specifiers log messages.
96 - Added a missing apostrophe in the 'More Privoxy' menu.
97 - Explicitly prevent use of FEATURE_CONNECTION_SHARING
98 without FEATURE_CONNECTION_KEEP_ALIVE. It makes no sense
99 and does not compile anyway.
100 Sponsored by: Robert Klemme
101 - Fix build without FEATURE_CONNECTION_KEEP_ALIVE.

103 - Downgrade the 'Graceful termination requested' message
104 to LOG_LEVEL_INFO as it isn't an error.
105 Sponsored by: Robert Klemme
106 - decompress_iob(): Downgrade the no-content message to LOG_LEVEL_RE_FILTER
107 While at it, fix a typo in a comment.
108 Sponsored by: Robert Klemme
109 - Fixed a couple of cppcheck warnings.
110 - Rename LOG_LEVEL_GPC to LOG_LEVEL_REQUEST.
111 Only the shadow knows what "GPC" is supposed to stand for.
112 - Remove SourceForge references in copyright headers.
113 - Upgrade a bunch of links to the homepage to https://.
114 - Add 'no-brotli-accepted' filter which prevents the
115 use of Brotli compression.
116 - Changed license for pcrs to GPLv2+ after getting the
117 permission from Andreas. This allows to redistribute
118 Privoxy under the GPLv3 which is required when linking
119 to future mbedTLS versions which are expected to be
120 licensed under the Apache 2.0 license only.
121 - Updated a bunch of tests that have to expect status code 403
122 now after r1.168/070e904afa5.
123 - Lowercase the host name in the request line.
124 - Only set SOURCE_DATE_EPOCH if it's not already set so
125 distributions can overwrite it through the environment.
127 - Documentation changes:
128 - Explain that Privoxy has to be distributed under the
129 GPLv3 (or later) when linked with an MbedTLS version
130 that is licensed under the Apache 2.0 license.
131 - Import the GNU GPLv3 and include it the user manual.
132 - Clarify FEATURE_FORCE_LOAD's description. It allows to bypass
133 blocking not filtering and only does it if blocks aren't enforced.
134 Reported by: Robert Klemme
135 - FAQ: Remove Zwiebelfreunde e.V. from the list of fiduciary sponsors
136 As of 2021 they no longer handle donations for foreign organisations
137 due to lack of resources.
138 - FAQ: Remove an obsolete comment with a link to the long-gone PDF manual.
139 - FAQ: Add a link to the TODO list.
140 - FAQ: Change the sponsor amounts to USD slightly rounding the
141 converted amounts up to get simple numbers.
142 Receiving USD is apparently easier for SPI and SPI is
143 preferred by sponsors as they can send invoices.
144 - Advertise the client-tags CGI page in the user manual.
145 - Stop advertising the show-version CGI page which no longer exists.
146 - Add yet another reason why +prevent-compression may cause problems.
147 - Don't claim that contributors need ssh. It's only needed for committers.
148 - Replace obsolete CVS instructions with Git instructions.
149 - Remove an obsolete comment
151 - Config file changes:
152 - Change the suggested default-server-timeout to 5 to match the
153 suggested keep-alive-timeout. Otherwise using the defaults would
154 result in Privoxy reducing the default-server-timeout and logging
156 Sponsored by: Robert Klemme
157 - Update the 'debug 1' description.
158 - Add a missing 'client-specific-tag' directive.
159 - Comment out trusted-cgi-referer pointing to example.org.
161 - Action file improvements:

191 - Added a +delay-response{} test.
192 - Updated the location of the development version
193 of default.action.master.
195 - Privoxy-Log-Parser:
196 - Added a --keep-date option to keep the date in highlighted messages.
197 - Highlight new log messages.
198 - Make gather_loglevel_clf_stats() more tolerant. While at it,
199 count all CLF messages as requests, even if the request is invalid.
200 - Only show HTTP version distribution if at least one version has been detected.
201 - Only show crunch statistics if crunches were detected.
202 - Warn if the request counts differ.
203 - Generate statistics if the log only contains LOG_LEVEL_CLF messages
204 so it can be used with vanilla webserver logs.
205 Previously Privoxy-specific "Request:" messages were required.
206 - Align the client-HTTP-version distribution like other distributions
207 - Bump version to 0.9.1
208 - Include status code distribution in the stats.
209 - Let the statistics include the size of the content Privoxy
210 transferred excluding HTTP headers.
211 - Get with the program and expect all requests to be logged with LOG_LEVEL_REQUEST.
212 It's no longer necessary to count both LOG_LEVEL_REQUEST and
213 LOG_LEVEL_CRUNCH messages to get the total number of requests.
214 - Leverage the LOG_LEVEL_CLF message to gather statistics that where
215 previously taken from LOG_LEVEL_HEADER lines. This results in less
216 confusing results if https inspection is enabled in which case there
217 are two LOG_LEVEL_HEADER lines with request lines.
218 Sponsored by: Robert Klemme
219 - Properly highlight the filter results message. Previously a brace got lost.
220 - Prefer the number of CLF lines to get the total number of requests
221 as it works with older Privoxy versions as well.
223 - Privoxy-Regression-Test:
224 - Turn curl's globbing mode off so we can allow more characters in URLs.
225 - Allow '[' and ']' in URLs.
226 - Include the action file when complaining about missing Sticky Actions.
227 - Fix a sentence in the documentation.
228 - Bump version to 0.7.1
230 - url-pattern-translator:
231 - Detect a couple of pattern prefixes case-insensitively.
232 Sponsored by: Robert Klemme
233 - Skip CLIENT-TAG patterns.

241 *** Version 3.0.28 stable ***
243 - Bug fixes for regressions in 3.0.27:
244 - Fixed misplaced parentheses.
245 Reported by David Binderman.
246 - Changed two regression tests to depend on config directive
247 enable-remote-toggle instead of FEATURE_TOGGLE.
249 *** Version 3.0.27 stable ***
251 - General improvements:
252 - Add a receive-buffer-size directive which can be used to
253 set the size of the previously statically allocated buffer
254 in handle_established_connection().
255 Increasing the buffer size increases Privoxy's memory usage but
256 can lower the number of context switches and thereby reduce the
257 CPU usage and potentially increase the throughput.
258 This is mostly relevant for fast network connections and
259 large downloads that don't require filtering.
260 Sponsored by: Robert Klemme
261 - Add a listen-backlog directive which specifies the backlog
262 value passed to listen().
263 Sponsored by: Robert Klemme
264 - Add an enable-accept-filter directive which allows to
265 toggle accept filter support at run time when compiled
266 with FEATURE_ACCEPT_FILTER support.
267 It makes testing more convenient and now that it's
268 optional we can emit an error message if enabling
269 the accept filter fails.
270 Sponsored by: Robert Klemme
271 - Add a delay-response{} action.
272 This is useful to tar pit JavaScript requests that
273 are endlessly retried in case of blocks. It can also
274 be used to simulate a slow Internet connection.
275 Sponsored by: Robert Klemme
276 - Add a 'trusted-cgi-referrer' directive.
277 It allows to configure another page or site that can be used
278 to reach sensitive CGI resources.
279 Sponsored by: Robert Klemme
280 - Add a --fuzz mode which exposes Privoxy internals to input
281 from files or stdout.
282 Mainly tested with American Fuzzy Lop. For details see:
283 https://www.fabiankeil.de/talks/fuzzing-on-freebsd/
284 This work was partially funded with donations and done
285 as part of the Privoxy month in 2015.
286 - Consistently use the U(ngreedy) flag in the 'img-reorder' filter.
287 - listen_loop(): Reuse a single thread attribute object
288 The object doesn't change and creating a new one for
289 every thread is a waste of (CPU) time.
290 Sponsored by: Robert Klemme
291 - Free csp resources in the thread that belongs to the csp instead
292 of the main thread which has enough on its plate already.
293 Sponsored by: Robert Klemme
294 - Improve 'socket timeout reached' message.
295 Log the timeout that was triggered and downgrade the
296 log level to LOG_LEVEL_CONNECT to reduce the log noise
297 with common debug settings.
298 The timeout isn't necessary the result of an error and
299 usually merely indicates that Privoxy's socket timeout
300 is lower than the relevant timeouts used by client and
302 Sponsored by: Robert Klemme
303 - Explicitly taint the server socket in case of CONNECT requests.
304 This doesn't fix any known problems, but makes
305 some log messages less confusing.
306 - Let write_pid_file() terminate if the pid file can't be opened.
307 Logging the issue at info level is unlikely to help.
308 - log_error(): Reduce the mutex-protected area by not using a
309 heap-allocated buffer that is shared between all threads.
310 This increases performance and reduces the latency with
311 verbose debug settings and multiple concurrent connections.
312 Sponsored by: Robert Klemme
313 - Let zalloc() use calloc() if it's available.
314 In some situations using calloc() can be faster than
315 malloc() + memset() and it should never be slower.
316 In the real world the impact of this change is not
317 expected to be noticeable.
318 Sponsored by: Robert Klemme
319 - Never use select() when poll() is available.
320 On most platforms select() is limited by FD_SETSIZE while
321 poll() is not. This was a scaling issue for multi-user setups.
322 Using poll() has no downside other than the usual risk
323 that code modifications may introduce new bugs that have
324 yet to be found and fixed.
325 At least in theory this commit could also reduce the latency
326 when there are lots of connections and select() would use
327 "bit fields in arrays of integers" to store file descriptors.
328 Another side effect is that Privoxy no longer has to stop
329 monitoring the client sockets when pipelined requests are
330 waiting but can't be read yet.
331 This code keeps the select()-based code behind ifdefs for
332 now but hopefully it can be removed soonish to make the

335 - Add a 'reproducible-tarball-dist' target.
336 It's currently separate from the "tarball-dist" target
337 because it requires a tar implementation with mtree spec
339 It's far from being perfect and does not enforce a
340 reproducible mode, but it's better than nothing.
341 - Use arc4random() if it's available.
342 While Privoxy doesn't need high quality pseudo-random numbers
343 there's no reason not to use them when we can and this silences
344 a warning emitted by code checkers that can't tell whether or not
346 - Show the FEATURE_EXTERNAL_FILTERS status on the status page.
347 Better late than never. Previously a couple of tests weren't
348 executed as Privoxy-Regression-Test couldn't detect that the
349 FEATURE_EXTERNAL_FILTERS dependency was satisfied.
350 - Ditch FEATURE_IMAGE_DETECT_MSIE.
351 It's an obsolete workaround we inherited from Junkbuster
352 and was already disabled by default.
353 Users that feel the urge to work around issues with
354 image requests coming from an Internet Explorer version
355 from more than 15 years ago can still do this using tags.
356 - Consistently use strdup_or_die() instead of strdup() in
357 cases where allocation failures aren't expected.
358 Using strdup_or_die() allows to remove a couple of explicit
359 error checks which slightly reduces the size of the binary.
360 - Insert a refresh tag into the /client-tags CGI page when
361 serving it while a client-specific tag is temporarily enabled.
362 This makes it less likely that the user ends up
363 looking at tag state that is out of date.
364 - Use absolute URLs in the client-tag forms.
365 It's more consistent with the rest of the CGI page
366 URLs and makes it more convenient to copy the forms
368 - cgi_error_disabled(): Use status code 403 and an appropriate response line
369 - Use a dedicated CGI handler to deal with tag-toggle requests
370 As a result the /client-tags page is now safe to reach without
371 trusted Referer header which makes bookmarking or linking to
373 Finally, refreshing the /client-tags page to show the
374 current state can no longer unintentionally repeat the
375 previous toggle request.
376 - Don't add a "Connection" header for CONNECT requests.
377 Explicitly sending "Connection: close" is not necessary and
378 apparently it causes problems with some forwarding proxies
379 that will close the connection prematurely.
380 Reported by Marc Thomas.
381 - Fix compiler warnings.
384 - rfc2553_connect_to(): Properly detect and log when poll()
385 reached the time out. Previously this was logged as:
386 Could not connect to [...]: No error: 0.
387 which isn't very helpful.
388 Sponsored by: Robert Klemme
389 - add_tag_for_client(): Set time_to_live properly.
390 Previously the time_to_live was always set for the first tag.
391 Attempts to temporarily enable a tag would result in enabling
392 it permanently unless no tag was enabled already.
393 - Revert r1.165 which didn't perform as advertised.
394 While the idea was to use "https:// when creating links
395 for the user manual on the website", the actual effect
396 was to use "https://" when Privoxy was supposed to serve
397 the user manual itself.
398 Reported by Yossi Zahn on Privoxy-devel@.
399 - socks5_connect(): Fail in case of unsupported address types.
400 Previously they would not be detected right away and
401 Privoxy would fail later on with an error message that
402 didn't make it obvious that the problem was socks-related.
403 So far, no such problems have actually been reported.
404 - socks5_connect(): Properly deal with socks replies that
405 contain IPv6 addresses.
406 Previously parts of the reply were left unread and
407 later on treated as invalid HTTP response data.
408 Fixes #904 reported by Danny Goossen who also provided
409 the initial version of this patch.
411 - Action file improvements:
412 - Unblock 'msdn.microsoft.com/'.
413 It (presumably) isn't used to serve the kind of ads Privoxy should
414 block by default but happens to serve lots of pages with URLs that
415 are likely to result in false positives.
416 Reported by bugreporter1694 in AF#939.
417 - Disable gif deanimation for requests tagged with CSS-REQUEST.
418 The action will ignore content that isn't considered text
419 anyway and explicitly disabling it makes this more obvious
420 if "action" debugging (debug 65536) is enabled while
421 "gif deanimation" debugging (debug 256) isn't.
422 - Explicitly disable HTML filters for requests with CSS-REQUEST tag.
423 The filters are unlikely to break CSS files but executing
424 them without (intentionally) getting any hits is a waste of
425 cpu time and makes the log more noisy when running with
427 - Unblock 'adventofcode.com/'.
428 Reported by Clint Adams in Debian bug #848211.
429 Fixes Roland's AF#937.
430 - Unblock 'adlibris.com'.

432 - Unblock .golang.org/
433 - Add fast-redirects exception for '.youtube.com/.*origin=http'
435 - Privoxy-Log-Parser:
436 - Don't gather host and resource statistics if they aren't requested.
437 While the performance impact seems negligible this significantly
438 reduces the memory usage if there are lots of requests.
439 - Bump version as the behaviour (slightly) changed.

445 statistics for a log file without response headers.
446 While privoxy-log-parser was supposed to detect this already,
447 the check was flawed and the message the user didn't see was
448 somewhat confusing anyway.
449 Now the message is less confusing, more helpful and actually printed.

452 - Documentation improvements:
453 - Refer to the git sources instead of CVS.
454 - Use GNU/Linux when referring to the OS instead of the kernel.
455 - Add FAQ entry for what to do if editing the config file is access denied.
456 - Add brief HTTP/2 FAQ.
457 - Add a small fuzzing section to the developer documentation.
458 - Add a client-header-tagger{client-ip-address} example.
459 - Stop suggesting that Privoxy is an anonymizing proxy.
460 The term could lead to Privoxy users overestimating
461 what it can do on its own (without Tor).
462 - Make it more obvious that SPI accepts Paypal, too.
463 Currently most donations are made through the Paypal account
464 managed by Zwiebelfreunde e.V. and a more even distribution
466 - Suggest to log applying actions as well when reproducing problems.
467 - Explicitly mention that Privoxy binaries are built by individuals
468 on their own systems. Buyer beware!
469 - Mention the release feed on the homepage.
470 - Remove a mysterious comment with a GNU FDL link as it isn't
471 useful and could confuse license scanners.
472 In May 2002 it was briefly claimed that "this document" was covered
473 by the GNU FDL. The commit message (r1.5) doesn't explain the motivation
474 or whether all copyright holders were actually asked and agreed to the
475 declared license change.
476 It's thus hard to tell whether or not the license change was legit,
477 but luckily two days later the "doc license" was "put" "back to GPL"
479 At the same time the offending comment with a link to the FDL
480 (not the GPL) was added for no obvious reason.
484 - Bump for-privoxy-version to 3.0.27 as we now rely on untrusted
485 CGI request being rejected with status code 403 (instead of 200).
486 - Update test for /send-stylesheet and add another one
489 - Consistently use https:// when linking to the Privoxy website.
490 - Remove SourceForge references in Copyright header.
491 - Remove a couple of SourceForge references in a comment.
492 While at it, fix the grammar.
493 - Move the site-specific documentation block before the generic one.
494 While most Privoxy installations don't have a site-specific
495 documentation block, in cases were it exists it's likely to
496 be more relevant than the generic one.
497 Showing it first makes it less likely that users stop reading
498 before they reach it, especially on pages that don't fit on
501 - Build system improvements:
502 - Prefer openjade to jade. On some systems Jade produces
503 HTML with unescaped ampersands in URLs.
504 - Prefer OpenSP to SP to be consistent.
505 - Have Docbook generated HTML files be straight ASCII.
506 Dealing with a mixture of ISO-8859 and UTF-8 files is problematic.
507 - Echo the filename to stderr for 'make dok-tidy'.
508 Make it a bit easier to find errors in docbook generated HTML.
509 - Warn when still using select().
510 - Warn when compiling without calloc().
511 - Make it more obvious that the --with-fdsetsize configure switch
512 is pointless if poll() is available.
513 - Remove support for AmigaOS.
514 - Update windows build system to use supported software.
515 The cygwin gcc -mno-cygwin option is no longer supported, so
516 convert the windows build system to use the cygwin cross-compiler
517 to build "native" code.
518 - Add --enable-static-linking option for configure
519 does the same thing as LDFLAGS=-static; ./configure
520 but nicer than mixing evars and configure options.
522 *** Version 3.0.26 stable ***
525 - Fixed crashes with "listen-addr :8118" (SF Bug #902).
526 The regression was introduced in 3.0.25 beta and reported
527 by Marvin Renich in Debian bug #834941.
529 - General improvements:
530 - Log when privoxy is toggled on or off via cgi interface.
531 - Highlight the "Info: Now toggled " on/off log message
532 in the Windows log viewer.
533 - Highlight the loading actions/filter file log message
534 in the Windows log viewer.
535 - Mention client-specific tags on the toggle page as a
536 potentionally more appropriate alternative.
538 - Documentation improvements:
539 - Update download section on the homepage.
540 The downloads are available from the website now.
542 - Remove obsolete reference to mailing lists hosted at SourceForge.
543 - Update the "Before the Release" section of the developer manual.
545 - Infrastructure improvements:
546 - Add perl script to generate an RSS feed for the packages
547 Submitted by "Unknown".
549 - Build system improvements:
550 - strptime.h: fix a compiler warning about ambiguous else.
551 - configure.in: Check for Docbook goo on the BSDs as well.
552 - GNUMakefile.in: Let the dok-user target remove temporary files.
554 *** Version 3.0.25 beta ***
557 - Always use the current toggle state for new requests.
558 Previously new requests on reused connections inherited
559 the toggle state from the previous request even though
560 the toggle state could have changed.
561 Reported by Robert Klemme.
562 - Fixed two buffer-overflows in the (deprecated) static
563 pcre code. These bugs are not considered security issues
564 as the input is trusted.
565 Found with afl-fuzz and ASAN.
567 - General improvements:
568 - Added support for client-specific tags which allow Privoxy
569 admins to pre-define tags that are set for all requests from
570 clients that previously opted in through the CGI interface.
571 They are useful in multi-user setups where admins may
572 want to allow users to disable certain actions and filters
573 for themselves without affecting others.
574 In single-user setups they are useful to allow more fine-grained
575 toggling. For example to disable request blocking while still
576 crunching cookies, or to disable experimental filters only.
577 This is an experimental feature, the syntax and behaviour may
578 change in future versions.
579 Sponsored by Robert Klemme.
580 - Dynamic filters and taggers now support a $listen-address variable
581 which contains the address the request came in on.
582 For external filters the variable is called $PRIVOXY_LISTEN_ADDRESS.
583 Original patch contributed by pursievro.
584 - Add client-header-tagger 'listen-address'.
585 - Include the listen-address in the log message when logging new requests.
586 Patch contributed by pursievro.
587 - Turn invalid max-client-connections values into fatal errors.
588 - The show-status page now shows whether or not dates before 1970
589 and after 2038 are expected to be handled properly.
590 This is mainly useful for Privoxy-Regression-Test but could
591 also come handy when dealing with time-related support requests.
592 - On Mac OS X the thread id in log messages are more likely to
594 - When complaining about missing filters, the filter type is logged
596 - A couple of harmless coverity warnings were silenced
597 (CID #161202, CID #161203, CID #161211).
599 - Action file improvements:
600 - Filtering is disabled for Range requests to let download resumption
601 and Windows updates work with the default configuration.
602 - Unblock ".ardmediathek.de/".
603 Reported by ThTomate in #932.
605 - Documentation improvements:
606 - Add FAQ entry for crashes caused by memory limits.
607 - Remove obsolete FAQ entry about a bug in PHP 4.2.3.
608 - Mention the new mailing lists were appropriate.
609 As the archives have not been migrated, continue to
610 mention the archives at SF in the contacting section
612 - Note that the templates should be adjusted if Privoxy is
613 running as intercepting proxy without getting all requests.
614 - A bunch of links were converted to https://.
615 - Rephrase onion service paragraph to make it more obvious
616 that Tor is involved and that the whole website (and not
617 just the homepage) is available as onion service.
618 - Streamline the "More information" section on the homepage further
619 by additionally ditching the link to the 'See also' section
620 of the user manual. The section contains mostly links that are
621 directly reachable from the homepage already and the rest is
622 not significant enough to get a link from the homepage.
623 - Change the add-header{} example to set the DNT header
624 and use a complete section to make copy and pasting
626 Add a comment to make it obvious that adding the
627 header is not recommended for obvious reasons.
628 Using the DNT header as example was suggested by
630 - Streamline the support-and-service template
631 Instead of linking to the various support trackers
632 (whose URLs hopefully change soon), link to the
633 contact section of the user manual to increase the
634 chances that users actually read it.
635 - Add a FAQ entry for tainted sockets.
636 - More sections in the documentation have stable URLs now.
637 - FAQ: Explain why 'ping config.privoxy.org' is not expected
638 to reach a local Privoxy installation.
639 - Note that donations done through Zwiebelfreunde e.V. currently
640 can't be checked automatically.
641 - Updated section regarding starting Privoxy under OS X.
642 - Use dedicated start instructions for FreeBSD and ElectroBSD.
643 - Removed release instructions for AIX. They haven't been working
644 for years and unsurprisingly nobody seems to care.
645 - Removed obsolete reference to the solaris-dist target.
646 - Updated the release instructions for FreeBSD.
647 - Removed unfinished release instructions for Amiga OS and HP-UX 11.
648 - Added a pointer to the Cygwin Time Machine for getting the last release of
649 Cygwin version 1.5 to use for building Privoxy on Windows.
650 - Various typos have been fixed.
652 - Infrastructure improvements:
653 - The website is no longer hosted at SourceForge and
654 can be reached through https now.
655 - The mailing lists at SourceForge have been deprecated,
656 you can subscribe to the new ones at: https://lists.privoxy.org/
657 - Migrating the remaining services from SourceForge is
658 work in progress (TODO list item #53).
660 - Build system improvements:
661 - Add configure argument to optimistically redefine FD_SETSIZE
662 with the intent to change the maximum number of client
663 connections Privoxy can handle. Only works with some libcs.
664 Sponsored by Robert Klemme.
665 - Let the tarball-dist target skip files in ".git".
666 - Let the tarball-dist target work in cwds other than current.
667 - Make the 'clean' target faster when run from a git repository.
668 - Include tools in the generic distribution.
669 - Let the gen-dist target work in cwds other than current.
670 - Sort find output that is used for distribution tarballs
671 to get reproducible results.
672 - Don't add '-src' to the name of the tar ball generated by the
673 gen-dist target. The package isn't a source distribution but a
675 While at it, use a variable for the name to reduce the chances
676 that the various references get out of sync and fix the gen-upload
677 target which was looking in the wrong directory.
678 - Add regression-tests.action to the files that are distributed.
679 - The gen-dist target which was broken since 2002 (r1.92) has been fixed.
680 - Remove genclspec.sh which has been obsolete since 2009.
681 - Remove obsolete reference to Redhat spec file.
682 - Remove the obsolete announce target which has been commented out years ago.
683 - Let rsync skip files if the checksums match.
685 - Privoxy-Regression-Test:
686 - Add a "Default level offset" directive which can be used to
687 change the default level by a given value.
688 This directive affects all tests located after it until the end
689 of the file or a another "Default level offset" directive is reached.
690 The purpose of this directive is to make it more convenient to skip
691 similar tests in a given file without having to remove or disable
692 the tests completely.
693 - Let test level 17 depend on FEATURE_64_BIT_TIME_T
694 instead of FEATURE_PTHREAD which has no direct connection
696 - Fix indentation in perldoc examples.
697 - Don't overlook directives in the first line of the action file.
698 - Bump version to 0.7.
699 - Fix detection of the Privoxy version now that https://
700 is used for the website.
702 *** Version 3.0.24 stable ***
704 - Security fixes (denial of service):
705 - Prevent invalid reads in case of corrupt chunk-encoded content.
706 CVE-2016-1982. Bug discovered with afl-fuzz and AddressSanitizer.
707 - Remove empty Host headers in client requests.
708 Previously they would result in invalid reads. CVE-2016-1983.
709 Bug discovered with afl-fuzz and AddressSanitizer.
712 - When using socks5t, send the request body optimistically as well.
713 Previously the request body wasn't guaranteed to be sent at all
714 and the error message incorrectly blamed the server.
715 Fixes #1686 reported by Peter Müller and G4JC.
716 - Fixed buffer scaling in execute_external_filter() that could lead
717 to crashes. Submitted by Yang Xia in #892.
718 - Fixed crashes when executing external filters on platforms like
719 Mac OS X. Reported by Jonathan McKenzie on ijbswa-users@.
720 - Properly parse ACL directives with ports when compiled with HAVE_RFC2553.
721 Previously the port wasn't removed from the host and in case of
722 'permit-access 127.0.0.1 example.org:80' Privoxy would try (and fail)
723 to resolve "example.org:80" instead of example.org.
724 Reported by Pak Chan on ijbswa-users@.
725 - Check requests more carefully before serving them forcefully
726 when blocks aren't enforced. Privoxy always adds the force token
727 at the beginning of the path, but would previously accept it anywhere
728 in the request line. This could result in requests being served that
729 should be blocked. For example in case of pages that were loaded with
730 force and contained JavaScript to create additionally requests that
731 embed the origin URL (thus inheriting the force prefix).
732 The bug is not considered a security issue and the fix does not make
733 it harder for remote sites to intentionally circumvent blocks if
734 Privoxy isn't configured to enforce them.
735 Fixes #1695 reported by Korda.
736 - Normalize the request line in intercepted requests to make rewriting
737 the destination more convenient. Previously rewrites for intercepted
738 requests were expected to fail unless $hostport was being used, but
739 they failed "the wrong way" and would result in an out-of-memory
740 message (vanilla host patterns) or a crash (extended host patterns).
741 Reported by "Guybrush Threepwood" in #1694.
742 - Enable socket lingering for the correct socket.
743 Previously it was repeatedly enabled for the listen socket
744 instead of for the accepted socket. The bug was found by
745 code inspection and did not cause any (reported) issues.
746 - Detect and reject parameters for parameter-less actions.
747 Previously they were silently ignored.
748 - Fixed invalid reads in internal and outdated pcre code.
749 Found with afl-fuzz and AddressSanitizer.
750 - Prevent invalid read when loading invalid action files.
751 Found with afl-fuzz and AddressSanitizer.
752 - Windows build: Use the correct function to close the event handle.
753 It's unclear if this bug had a negative impact on Privoxy's behaviour.
754 Reported by Jarry Xu in #891.
755 - In case of invalid forward-socks5(t) directives, use the
756 correct directive name in the error messages. Previously they
757 referred to forward-socks4t failures.
758 Reported by Joel Verhagen in #889.
760 - General improvements:
761 - Set NO_DELAY flag for the accepting socket. This significantly reduces
762 the latency if the operating system is not configured to set the flag
763 by default. Reported by Johan Sintorn in #894.
764 - Allow to build with mingw x86_64. Submitted by Rustam Abdullaev in #135.
765 - Introduce the new forwarding type 'forward-webserver'.
766 Currently it is only supported by the forward-override{} action and
767 there's no config directive with the same name. The forwarding type
768 is similar to 'forward', but the request line only contains the path
769 instead of the complete URL.
770 - The CGI editor no longer treats 'standard.action' special.
771 Nowadays the official "standards" are part of default.action
772 and there's no obvious reason to disallow editing them through
773 the cgi editor anyway (if the user decided that the lack of
774 authentication isn't an issue in her environment).
775 - Improved error messages when rejecting intercepted requests
776 with unknown destination.
777 - A couple of log messages now include the number of active threads.
778 - Removed non-standard Proxy-Agent headers in HTTP snipplets
779 to make testing more convenient.
780 - Include the error code for pcre errors Privoxy does not recognize.
781 - Config directives with numerical arguments are checked more carefully.
782 - Privoxy's malloc() wrapper has been changed to prevent zero-size
783 allocations which should only occur as the result of bugs.
784 - Various cosmetic changes.
786 - Action file improvements:
787 - Unblock ".deutschlandradiokultur.de/".
788 Reported by u302320 in #924.
789 - Add two fast-redirect exceptions for "yandex.ru".
790 - Disable filter{banners-by-size} for ".plasmaservice.de/".
791 - Unblock "klikki.fi/adv/".
792 - Block requests for "resources.infolinks.com/".
793 Reported by "Black Rider" on ijbswa-users@.
794 - Block a bunch of criteo domains.
795 Reported by Black Rider.
796 - Block "abs.proxistore.com/abe/".
797 Reported by Black Rider.
798 - Disable filter{banners-by-size} for ".black-mosquito.org/".
799 - Disable fast-redirects for "disqus.com/".
801 - Documentation improvements:
802 - FAQ: Explicitly point fingers at ASUS as an example of a
803 company that has been reported to force malware based on
804 Privoxy upon its customers.
805 - Correctly document the action type for a bunch of "multi-value"
806 actions that were incorrectly documented to be "parameterized".
807 Reported by Gregory Seidman on ijbswa-users@.
808 - Fixed the documented type of the forward-override{} action
809 which is obviously 'parameterized'.
811 - Website improvements:
812 - Users who don't trust binaries served by SourceForge
813 can get them from a mirror. Migrating away from SourceForge
814 is planned for 2016 (TODO list item #53).
815 - The website is now available as onion service
816 (http://jvauzb4sb3bwlsnc.onion/).
818 *** Version 3.0.23 stable ***
821 - Fixed a DoS issue in case of client requests with incorrect
822 chunk-encoded body. When compiled with assertions enabled
823 (the default) they could previously cause Privoxy to abort().
824 Reported by Matthew Daley. CVE-2015-1380.
825 - Fixed multiple segmentation faults and memory leaks in the
826 pcrs code. This fix also increases the chances that an invalid
827 pcrs command is rejected as such. Previously some invalid commands
828 would be loaded without error. Note that Privoxy's pcrs sources
829 (action and filter files) are considered trustworthy input and
830 should not be writable by untrusted third-parties. CVE-2015-1381.
831 - Fixed an 'invalid read' bug which could at least theoretically
832 cause Privoxy to crash. So far, no crashes have been observed.
834 - Compiles with --disable-force again. Reported by Kai Raven.
835 - Client requests with body that can't be delivered no longer
836 cause pipelined requests behind them to be rejected as invalid.
837 Reported by Basil Hussain.
839 - General improvements:
840 - If a pcrs command is rejected as invalid, Privoxy now logs
841 the cause of the problem as text. Previously the pcrs error
843 - The tests are less likely to cause false positives.
845 - Action file improvements:
846 - '.sify.com/' is no longer blocked. Apparently it is not actually
847 a pure tracking site (anymore?). Reported by Andrew on ijbswa-users@.
848 - Unblock banners on .amnesty.de/ which aren't ads.
850 - Documentation improvements:
851 - The 'Would you like to donate?' section now also contains
853 - The list of supported operating systems has been updated.
854 - The existence of the SF support and feature trackers has been
855 deemphasized because they have been broken for months.
856 Most of the time the mailing lists still work.
857 - The claim that default.action updates are sometimes released
858 on their own has been removed. It hasn't happened in years.
859 - Explicitly mention that Tor's port may deviate from the default
860 when using a bundle. Requested by Andrew on ijbswa-users@.
862 *** Version 3.0.22 stable ***
865 - Fixed a memory leak when rejecting client connections due to
866 the socket limit being reached (CID 66382). This affected
867 Privoxy 3.0.21 when compiled with IPv6 support (on most
868 platforms this is the default). CVE-2015-1030.
869 - Fixed an immediate-use-after-free bug (CID 66394) and two
870 additional unconfirmed use-after-free complaints made by
871 Coverity scan (CID 66391, CID 66376). CVE-2015-1031.
872 - Actually show the FORCE_PREFIX value on the show-status page.
873 - Properly deal with Keep-Alive headers with timeout= parameters
874 If the timeout still can't be parsed, use the configured
875 timeout instead of preventing the client from keeping the
876 connection alive. Fixes #3615312/#870 reported by Bernard Guillot.
877 - Not using any filter files no longer results in warning messages
878 unless an action file is referencing header taggers or filters.
879 Reported by Stefan Kurtz in #3614835.
880 - Fixed a bug that prevented Privoxy from reusing some reusable
881 connections. Two bit masks with different purpose unintentionally
883 - A couple of additional bugs were discovered by Coverity Scan.
884 The fixes that are not expected to affect users are not explicitly
885 mentioned here, for details please have a look at the CVS logs.
887 - General improvements:
888 - Introduced negative tag patterns NO-REQUEST-TAG and NO-RESPONSE-TAG.
889 They apply if no matching tag is found after parsing client or
891 - Add support for external filters which allow to process the
892 response body with a script or program written in any language
893 the platform supports. External filters are enabled with
894 +external-filter{} after they have been defined in one of the
895 filter files with a header line starting with "EXTERNAL-FILTER:".
896 External filter support is experimental, not compiled by default
897 and known not to work on all platforms.
898 - Add support for the 'PATCH' method as defined in RFC5789.
899 - Reject requests with unsupported Expect header values.
900 Fixes a couple of Co-Advisor tests.
901 - Normalize the HTTP-version in forwarded requests and responses.
902 This is an explicit RFC 2616 MUST and RFC 7230 mandates that
903 intermediaries send their own HTTP-version in forwarded
905 - Server 'Keep-Alive' headers are no longer forwarded. From a user's
906 point of view it doesn't really matter, but RFC 2616 (obsolete)
907 mandates that the header is removed and this fixes a Co-Advisor
909 - Change declared template file encoding to UTF-8. The templates
910 already used a subset of UTF-8 anyway and changing the declaration
911 allows to properly display UTF-8 characters used in the action files.
912 This change may require existing action files with ISO-8859-1
913 characters that aren't valid UTF-8 to be converted to UTF-8.
914 Requested by Sam Chen in #582.
915 - Do not pass rejected keep-alive timeouts to the server. It might
916 not have caused any problems (we know of), but doing the right
917 thing shouldn't hurt either.
918 - Let log_error() use its own buffer size #define to make changing
919 the log buffer size slightly less inconvenient.
920 - Turned single-threaded into a "proper" toggle directive with arguments.
921 - CGI templates no longer enforce new windows for some links.
922 - Remove an undocumented workaround ('HOST' header removal) for
923 an Apple iTunes bug that according to #729900 got fixed in 2003.
925 - Action file improvements:
926 - The pattern 'promotions.' is no longer being blocked.
927 Reported by rakista in #3608540.
928 - Disable fast-redirects for .microsofttranslator.com/.
929 - Disable filter{banners-by-size} for .dgb-tagungszentren.de/.
930 - Add adn.speedtest.net as a site-specific unblocker.
931 Support request #3612908.
932 - Disable filter{banners-by-size} for creativecommons.org/.
933 - Block requests to data.gosquared.com/. Reported by cbug in #3613653.
934 - Unblock .conrad./newsletter/. Reported by David Bo in #3614238.
935 - Unblock .bundestag.de/.
936 - Unblock .rote-hilfe.de/.
937 - Disable fast-redirects for .facebook.com/plugins/like.php.
938 - Unblock Stackexchange popup URLs that aren't used to serve ads.
939 Reported by David Wagner in #3615179.
940 - Disable fast-redirects for creativecommons.org/.
941 - Unblock .stopwatchingus.info/.
942 - Block requests for .adcash.com/script/.
943 Reported by Tyrexionibus in #3615289.
944 - Disable HTML filters if the response was tagged as JavaScript.
945 Filtering JavaScript code with filters intended to deal with HTML
946 is usually a waste of time and, more importantly, may break stuff.
947 - Use a custom redirect{} for .washingtonpost.com/wp-apps/imrs\.php\?src=
948 Previously enabling the 'Advanced' settings (or manually enabling
949 +fast-redirects{}) prevented some images from being loaded properly.
950 - Unblock "adina*." Fixes #919 reported by Morton A. Goldberg.
952 - Unblock 'adele*.'. Reported by Adele Lime in #1663.
953 - Disable banners-by-size for kggp.de/.
955 - Filter file improvements & bug fixes:
956 - Decrease the chances that js-annoyances creates invalid JavaScript.
957 Submitted by John McGowan on ijbswa-users@.
958 - Let the msn filter hide 'related' ads again.
959 - Remove a stray '1' in the 'html-annoyances' filter.
960 - Prevent img-reorder from messing up img tags with empty src
961 attributes. Fixes #880 reported by Duncan.
963 - Documentation improvements:
964 - Updated the 'Would you like to donate?' section.
965 - Note that invalid forward-override{} parameter syntax isn't
966 detected until the parameter is used.
967 - Add another +redirect{} example: a shortcut for illumos bugs.
968 - Make it more obvious that many operating systems support log
969 rotation out of the box.
970 - Fixed dead links. Reported by Mark Nelson in #3614557.
971 - Rephrased the 'Why is the configuration so complicated?' answer
972 to be slightly less condescending. Anonymously suggested in #3615122.
973 - Be more explicit about accept-intercepted-requests's lack of MITM support.
974 - Make 'demoronizer' FAQ entries more generic.
975 - Add an example hostname to the --pre-chroot-nslookup description.
976 - Add an example for a host pattern that matches an IP address.
977 - Rename the 'domain pattern' to 'host pattern' as it may
978 contain IP addresses as well.
979 - Recommend forward-socks5t when using Tor. It seems to work fine and
980 modifying the Tor configuration to profit from it hasn't been necessary
982 - Add another redirect{} example to stress that redirect loops can
983 and should be avoided.
984 - The usual spelling and grammar fixes. Parts of them were
985 reported by Reuben Thomas in #3615276.
986 - Mention the PCRS option letters T and D in the filter section.
987 - Clarify that handle-as-empty-doc-returns-ok is still useful
988 and will not be removed without replacement.
989 - Note that security issues shouldn't be reported using the bug tracker.
990 - Clarify what Privoxy does if both +block{} and +redirect{} apply.
991 - Removed the obsolete bookmarklets section.
993 - Build system improvements:
994 - Let --with-group properly deal with secondary groups.
995 Patch submitted by Anatoly Arzhnikov in #3615187.
996 - Fix web-actions target.
997 - Add a web-faq target that only updates the FAQ on the webserver.
998 - Remove already-commented-out non-portable DOSFILTER alternatives.
999 - Remove the obsolete targets dok-put and dok-get.
1000 - Add a sf-shell target.
1002 *** Version 3.0.21 stable ***
1005 - On POSIX-like platforms, network sockets with file descriptor
1006 values above FD_SETSIZE are properly rejected. Previously they
1007 could cause memory corruption in configurations that allowed
1008 the limit to be reached.
1009 - Proxy authentication headers are removed unless the new directive
1010 enable-proxy-authentication-forwarding is used. Forwarding the
1011 headers potentially allows malicious sites to trick the user
1012 into providing them with login information.
1013 Reported by Chris John Riley.
1014 - Compiles on OS/2 again now that unistd.h is only included
1015 on platforms that have it.
1017 - General improvements:
1018 - The show-status page shows the FEATURE_STRPTIME_SANITY_CHECKS status.
1019 - A couple of assert()s that could theoretically dereference
1020 NULL pointers in debug builds have been relocated.
1021 - Added an LSB info block to the generic start script.
1022 Based on a patch from Natxo Asenjo.
1023 - The max-client-connections default has been changed to 128
1024 which should be more than enough for most setups.
1026 - Action file improvements:
1027 - Block rover.ebay./ar.*\&adtype= instead of "/.*\&adtype=" which
1028 caused too man false positives.
1029 Reported by u302320 in #360284, additional feedback from Adam Piggott.
1030 - Unblock '.advrider.com/' and '/.*ADVrider'.
1031 Anonymously reported in #3603636.
1032 - Stop blocking '/js/slider\.js'.
1033 Reported by Adam Piggott in #3606635 and _lvm in #2791160.
1035 - Filter file improvements:
1036 - Added an iframes filter.
1038 - Documentation improvements:
1039 - The whole GPLv2 text is included in the user manual now,
1040 so Privoxy can serve it itself and the user can read it
1041 without having to wade through GPLv3 ads first.
1042 - Properly numbered and underlined a couple of section titles
1043 in the config that where previously overlooked due to a flaw
1044 in the conversion script. Reported by Ralf Jungblut.
1045 - Improved the support instruction to hopefully make it harder to
1046 unintentionally provide insufficient information when requesting
1047 support. Previously it wasn't obvious that the information we need
1048 in bug reports is usually also required in support requests.
1049 - Removed documentation about packages that haven't been provided
1052 - Privoxy-Regression-Test:
1053 - Only log the test number when not running in verbose mode
1054 The position of the test is rarely relevant and it previously
1055 wasn't exactly obvious which one of the numbers was useful to
1056 repeat the test with --test-number.
1058 - GNUmakefile improvements:
1059 - Factor generate-config-file out of config-file to make testing
1061 - The clean target now also takes care of patch leftovers.
1063 *** Version 3.0.20 beta ***
1066 - Client sockets are now properly shutdown and drained before being
1067 closed. This fixes page truncation issues with clients that aggressively
1068 pipeline data on platforms that otherwise discard already written data.
1069 The issue mainly affected Opera users and was initially reported
1070 by Kevin in #3464439, szotsaki provided additional information to track
1072 - Fix latency calculation for shared connections (disabled by default).
1073 It was broken since their introduction in 2009. The calculated latency
1074 for most connections would be 0 in which case the timeout detection
1075 failed to account for the real latency.
1076 - Reject URLs with invalid port. Previously they were parsed incorrectly and
1077 characters between the port number and the first slash were silently
1078 dropped as shown by curl test 187.
1079 - The default-server-timeout and socket-timeout directives accept 0 as
1081 - Fix a race condition on Windows that could cause Privoxy to become
1082 unresponsive after toggling it on or off through the taskbar icon.
1083 Reported by Tim H. in #3525694.
1084 - Fix the compilation on Windows when configured without IPv6 support.
1085 - Fix an assertion that could cause debug builds to abort() in case of
1086 socks5 connection failures with "debug 2" enabled.
1087 - Fix an assertion that could cause debug builds to abort() if a filter
1088 contained nul bytes in the replacement text.
1090 - General improvements:
1091 - Significantly improved keep-alive support for both client and server
1093 - New debug log level 65536 which logs all actions that were applied to
1095 - New directive client-header-order to forward client headers in a
1096 different order than the one in which they arrived.
1097 - New directive tolerate-pipelining to allow client-side pipelining.
1098 If enabled (3.0.20 beta enables it by default), Privoxy will keep
1099 pipelined client requests around to deal with them once the current
1100 request has been served.
1101 - New --config-test option to let Privoxy exit after checking whether or not
1102 the configuration seems valid. The limitations noted in TODO #22 and #23
1103 still apply. Based on a patch by Ramkumar Chinchani.
1104 - New limit-cookie-lifetime{} action to let cookies expire before the end
1105 of the session. Suggested by Rick Sykes in #1049575.
1106 - Increase the hard-coded maximum number of actions and filter files from
1107 10 to 30 (each). It doesn't significantly affect Privoxy's memory usage
1108 and recompiling wasn't an option for all Privoxy users that reached the
1110 - Add support for chunk-encoded client request bodies. Previously
1111 chunk-encoded request bodies weren't guaranteed to be forwarded correctly,
1112 so this can also be considered a bug fix although chunk-encoded request
1113 bodies aren't commonly used in the real world.
1114 - Add support for Tor's optimistic-data SOCKS extension, which can reduce the
1115 latency for requests on newly created connections. Currently only the
1116 headers are sent optimistically and only if the client request has already
1117 been read completely which rules out requests with large bodies.
1118 - After preventing the client from pipelining, don't signal keep-alive
1119 intentions. When looking at the response headers alone, it previously
1120 wasn't obvious from the client's perspective that no additional responses
1122 - Stop considering client sockets tainted after receiving a request with body.
1123 It hasn't been necessary for a while now and unnecessarily causes test
1124 failures when using curl's test suite.
1125 - Allow HTTP/1.0 clients to signal interest in keep-alive through the
1126 Proxy-Connection header. While such client are rare in the real world, it
1127 doesn't hurt and couple of curl tests rely on it.
1128 - Only remove duplicated Content-Type headers when filters are enabled.
1129 If they are not it doesn't cause ill effects and the user might not want it.
1130 Downgrade the removal message to LOG_LEVEL_HEADER to clarify that it's not
1131 an error in Privoxy and is unlikely to cause any problems in general.
1132 Anonymously reported in #3599335.
1133 - Set the socket option SO_LINGER for the client socket.
1134 - Move several variable declarations to the beginning of their code block.
1135 It's required when compiling with gcc 2.95 which is still used on some
1136 platforms. Initial patch submitted by Simon South in #3564815.
1137 - Optionally try to sanity-check strptime() results before trusting them.
1138 Broken strptime() implementations have caused problems in the past and
1139 the most recent offender seems to be FreeBSD's libc (standards/173421).
1140 - When filtering is enabled, let Range headers pass if the range starts at
1141 the beginning. This should work around (or at least reduce) the video
1142 playback issues with various Apple clients as reported by Duc in #3426305.
1143 - Do not confuse a client hanging up with a connection time out. If a client
1144 closes its side of the connection without sending a request line, do not
1145 send the CLIENT_CONNECTION_TIMEOUT_RESPONSE, but report the condition
1147 - Allow closing curly braces as part of action values as long as they are
1149 - On Windows, the logfile is now written before showing the GUI error
1150 message which blocks until the user acknowledges it.
1151 Reported by Adriaan in #3593603.
1152 - Remove an unreasonable parameter limit in the CGI interface. The new
1153 parameter limit depends on the memory available and is currently unlikely
1154 to be reachable, due to other limits in both Privoxy and common clients.
1155 Reported by Andrew on ijbswa-users@.
1156 - Decrease the chances of parse failures after requests with unsupported
1157 methods were sent to the CGI interface.
1159 - Action file improvements:
1160 - Remove the comment that indicated that updated default.action versions
1161 are released on their own.
1162 - Block 'optimize.indieclick.com/' and 'optimized-by.rubiconproject.com/'
1163 - Unblock 'adjamblog.wordpress.com/' and 'adjamblog.files.wordpress.com/'.

1202 Fixes #3413827 submitted by David Bo.
1203 - Add two unblock patterns for popup radio and TV players.
1204 Submitted by Adam Piggott in #3596089.
1206 - Filter file improvements & bug fixes:
1207 - Add a referer tagger.
1208 - Reduce the likelihood that the google filter messes up HTML-generating
1209 JavaScript. Reported by Zeno Kugy in #3520260.
1211 - Documentation improvements:
1212 - Revised all OS X sections due to new packaging module (OSXPackageBuilder).
1213 - Update the list of supported operating systems to clarify that all Windows
1214 versions after 95 are expected to work and note that the platform-specific
1215 code for AmigaOS and QNX currently isn't maintained.
1216 - Update 'Signals' section, the only explicitly handled signals are SIGINT,
1218 - Add Haiku to the list of operating systems on which Privoxy is known to
1220 - Add DragonFly to the list of BSDs on which Privoxy is known to run.
1221 - Removed references to redhat-specific documentation set since it no longer
1223 - Removed references to building PDFs since we no longer do so.
1224 - Multiple listen-address directives are supported since 3.0.18, correct the
1225 documentation to say so.
1226 - Remove bogus section about long and short being preferable to int.
1227 - Corrected some Internet JunkBuster references to Privoxy.
1228 - Removed references to www.junkbusters.com since it is no longer
1229 maintained. Reported by Angelina Matson.
1230 - Various grammar and spelling corrections
1231 - Add a client-header-tagger{} example for disabling filtering for range
1233 - Correct a URL in the "Privoxy with Tor" FAQ.
1234 - Spell 'refresh-tags' correctly. Reported by Don in #3571927.
1235 - Sort manpage options alphabetically.
1236 - Remove an incorrect sentence in the toggle section. The toggle state
1237 doesn't affect whether or not the Windows version uses the tray icon.
1238 Reported by Zeno Kugy in #3596395.
1239 - Add new contributors since 3.0.19.
1241 - Log message improvements:
1242 - When stopping to watch a client socket due to pipelining, additionally log
1244 - Log the client socket and its condition before closing it. This makes it
1245 more obvious that the socket actually gets closed and should help when
1246 diagnosing problems like #3464439.
1247 - In case of SOCKS5 failures, do not explicitly log the server's response.
1248 It hasn't helped so far and the response can already be logged by enabling
1249 "debug 32768" anyway. This reverts v1.81 and the follow-up bug fix v1.84.
1250 - Relocate the connection-accepted message from listen_loop() to serve().
1251 This way it's printed by the thread that is actually serving the
1252 connection which is nice when grepping for thread ids in log files.
1255 - Remove compatibility layer for versions prior to 3.0 since it has been
1256 obsolete for more than 10 years now.
1257 - Remove the ijb_isupper() and ijb_tolower() macros from parsers.c since
1258 they aren't used in this file.
1259 - Removed the 'Functions declared include:' comment sections since they tend
1260 to be incomplete, incorrect and out of date and the benefit seems
1262 - Various comment grammar and comprehensibility improvements.
1263 - Remove a pointless fflush() call in chat(). Flushing all streams pretty
1264 much all the time for no obvious reason is ridiculous.
1265 - Relocate ijb_isupper()'s definition to project.h and get the ijb_tolower()
1266 definition from there, too.
1267 - Relocate ijb_isdigit()'s definition to project.h.
1268 - Rename ijb_foo macros to privoxy_foo.
1269 - Add malloc_or_die() which will allow to simplify code paths where malloc()
1270 failures don't need to be handled gracefully.
1271 - Add strdup_or_die() which will allow to simplify code paths where strdup()
1272 failures don't need to be handled gracefully.
1273 - Replace strdup() calls with strdup_or_die() calls where it's safe and
1274 simplifies the code.
1275 - Fix white-space around parentheses.
1276 - Add missing white-space behind if's and the following parentheses.
1277 - Unwrap a memcpy() call in resolve_hostname_to_ip().
1278 - Declare pcrs_get_delimiter()'s delimiters[] static const.
1279 - Various optimisations to remove dead code and merge inefficient code
1280 structures for improved clarity, performance or code compactness.
1281 - Various data type corrections.
1282 - Change visibility of several code segments when compiling without
1283 FEATURE_CONNECTION_KEEP_ALIVE enabled for clarity.
1284 - In pcrs_get_delimiter(), do not use delimiters outside the ASCII range.
1285 Fixes a clang complaint.
1286 - Fix an error message in get_last_url() nobody is supposed to see.
1287 Reported by Matthew Fischer in #3507301.
1288 - Fix a typo in the no-zlib-support complaint. Patch submitted by Matthew
1289 Fischer in #3507304.
1290 - Shorten ssplit()'s prototype by removing the last two arguments. We always
1291 want to skip empty fields and ignore leading delimiters, so having
1292 parameters for this only complicates the API.
1293 - Use an enum for the type of the action value.
1294 - Rename action_name's member takes_value to value_type as it isn't used as
1296 - Turn family mismatches in match_sockaddr() into fatal errors.
1297 - Let enlist_unique_header() verify that the caller didn't pass a header
1298 containing either \r or \n.
1299 - Change the hashes used in load_config() to unsigned int. That's what
1300 hash_string() actually returns and using a potentially larger type
1302 - Use privoxy_tolower() instead of vanilla tolower() with manual casting of
1304 - Catch ssplit() failures in parse_cgi_parameters().
1306 - Privoxy-Regression-Test:
1307 - Add an 'Overwrite condition' directive to skip any matching tests before
1308 it. As it has a global scope, using it is more convenient than clowning
1309 around with the Ignore directive.
1310 - Log to STDOUT instead of STDERR.
1311 - Include the Privoxy version in the output.
1312 - Various grammar and spelling corrections in documentation and code.
1313 - Additional tests for range requests with filtering enabled.
1314 - Tests with mostly invalid range request.
1315 - Add a couple of hide-if-modified-since{} tests with different date formats.
1316 - Cleaned up the format of the regression-tests.action file to match the
1317 format of default.action.
1318 - Remove the "Copyright" line from print_version(). When using --help, every
1319 line of screen space matters and thus shouldn't be wasted on things the
1320 user doesn't care about.
1322 - Privoxy-Log-Parser:
1323 - Improve the --statistics performance by skipping sanity checks for input
1324 that shouldn't affect the results anyway. Add a --strict-checks option
1325 that enables some of the checks again, just in case anybody cares.
1326 - The distribution of client requests per connection is included in
1327 the --statistic output.
1328 - The --accept-unknown-messages option has been removed and the behavior
1330 - Accept and (mostly) highlight new log messages introduced with
1334 - Bump generated Firefox version to 17.
1336 - GNUmakefile improvements:
1337 - The dok-tidy target no longer taints documents with a tidy-mark
1338 - Change RA_MODE from 0664 to 0644. Suggested by Markus Dittrich in
1340 - Remove tidy's clean flag as it changes the scope of attributes.
1341 Link-specific colors end up being applied to all text. Reported by Adam
1342 Piggott in #3569551.
1343 - Leave it up to the user whether or not smart tags are inserted.
1344 - Let w3m itself do the line wrapping for the config file. It works better
1345 than fmt as it can honour pre tags causing less unintentional line breaks.
1346 - Ditch a pointless '-r' passed to rm to delete files.
1347 - The config-file target now requires less manual intervention and updates
1348 the original config.
1349 - Change WDUMP to generate ASCII. Add WDUMP_UTF8 to allow UTF-8 in the
1350 AUTHORS file so the names are right.
1351 - Stop pretending that lynx and links are supported for the documentation.
1353 - configure improvements:
1354 - On Haiku, do not pass -lpthread to the compiler. Haiku's pthreads
1355 implementation is contained in its system library, libroot, so no
1356 additional library needs to be searched.
1357 Patch submitted by Simon South in #3564815.
1358 - Additional Haiku-specific improvements. Disable checks intended for
1359 multi-user systems as Haiku is presently single-user. Group Haiku-specific
1360 settings in their own section, following the pattern for Solaris, OS/2 and
1361 AmigaOS. Add additional library-related settings to remove the need for
1362 providing configure with custom LDFLAGS.
1363 Submitted by Simon South in #3574538.
1365 *** Version 3.0.19 Stable ***
1368 - Prevent a segmentation fault when de-chunking buffered content.
1369 It could be triggered by malicious web servers if Privoxy was
1370 configured to filter the content and running on a platform
1371 where SIZE_T_MAX isn't larger than UINT_MAX, which probably
1372 includes most 32-bit systems. On those platforms, all Privoxy
1373 versions before 3.0.19 appear to be affected.
1374 To be on the safe side, this bug should be presumed to allow
1375 code execution as proving that it doesn't seems unrealistic.
1376 - Do not expect a response from the SOCKS4/4A server until it
1377 got something to respond to. This regression was introduced
1378 in 3.0.18 and prevented the SOCKS4/4A negotiation from working.
1379 Reported by qqqqqw in #3459781.
1381 - General improvements:
1382 - Fix an off-by-one in an error message about connect failures.
1383 - Use a GNUMakefile variable for the webserver root directory and
1384 update the path. Sourceforge changed it which broke various
1385 web-related targets.
1386 - Update the CODE_STATUS description.
1388 *** Version 3.0.18 Stable ***
1391 - If a generated redirect URL contains characters RFC 3986 doesn't
1392 permit, they are (re)encoded. Not doing this makes Privoxy versions
1393 from 3.0.5 to 3.0.17 susceptible to HTTP response splitting (CWE-113)
1394 attacks if the +fast-redirects{check-decoded-url} action is used.
1395 - Fix a logic bug that could cause Privoxy to reuse a server
1396 socket after it got tainted by a server-header-tagger-induced
1397 block that was triggered before the whole server response had
1398 been read. If keep-alive was enabled and the request following
1399 the blocked one was to the same host and using the same forwarding
1400 settings, Privoxy would send it on the tainted server socket.
1401 While the server would simply treat it as a pipelined request,
1402 Privoxy would later on fail to properly parse the server's
1403 response as it would try to parse the unread data from the
1404 first response as server headers for the second one.
1405 Regression introduced in 3.0.17.
1406 - When implying keep-alive in client_connection(), remember that
1407 the client didn't. Fixes a regression introduced in 3.0.13 that
1408 would cause Privoxy to wait for additional client requests after
1409 receiving a HTTP/1.1 request with "Connection: close" set
1410 and connection sharing enabled.
1411 With clients which terminates the client connection after detecting
1412 that the whole body has been received it doesn't really matter,
1413 but with clients that don't the connection would be kept open until
1415 - Fix a subtle race condition between prepare_csp_for_next_request()
1416 and sweep(). A thread preparing itself for the next client request
1417 could briefly appear to be inactive.
1418 If all other threads were already using more recent files,
1419 the thread could get its files swept away under its feet.
1420 So far this has only been reproduced while stress testing in
1421 valgrind while touching action files in a loop. It's unlikely
1422 to have caused any actual problems in the real world.
1423 - Disable filters if SDCH compression is used unless filtering is forced.
1424 If SDCH was combined with a supported compression algorithm, Privoxy
1425 previously could try to decompress it and ditch the Content-Encoding
1426 header even though the SDCH compression wasn't dealt with.
1427 Reported by zebul666 in #3225863.
1428 - Make a copy of the --user value and only mess with that when splitting
1429 user and group. On some operating systems modifying the value directly
1430 is reflected in the output of ps and friends and can be misleading.
1431 Reported by zepard in #3292710.
1432 - If forwarded-connect-retries is set, only retry if Privoxy is actually
1433 forwarding the request. Previously direct connections would be retried
1435 - Fixed a small memory leak when retrying connections with IPv6
1437 - Remove an incorrect assertion in compile_dynamic_pcrs_job_list()
1438 It could be triggered by a pcrs job with an invalid pcre
1439 pattern (for example one that contains a lone quantifier).
1440 - If the --user argument user[.group] contains a dot, always bail out
1441 if no group has been specified. Previously the intended, but undocumented
1442 (and apparently untested), behaviour was to try interpreting the whole
1443 argument as user name, but the detection was flawed and checked for '0'
1444 instead of '\0', thus merely preventing group names beginning with a zero.
1445 - In html_code_map[], use a numeric character reference instead of '
1446 which wasn't standardized before XHTML 1.0.
1447 - Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION
1448 and shut down through http://config.privoxy.org/die
1449 - In get_actions(), fix the "temporary" backwards compatibility hack
1450 to accept block actions without reason.
1451 It also covered other actions that should be rejected as invalid.
1452 Reported by Billy Crook.
1454 - General improvements:
1455 - Privoxy can (re)compress buffered content before delivering
1456 it to the client. Disabled by default as most users wouldn't
1458 - The +fast-redirects{check-decoded-url} action checks URL
1459 segments separately. If there are other parameters behind
1460 the redirect URL, this makes it unnecessary to cut them off
1461 by additionally using a +redirect{} pcrs command.
1462 Initial patch submitted by Jamie Zawinski in #3429848.
1463 - When loading action sections, verify that the referenced filters
1464 exist. Currently missing filters only result in an error message,
1465 but eventually the severity will be upgraded to fatal.
1466 - Allow to bind to multiple separate addresses.
1467 Patch set submitted by Petr Pisar in #3354485.
1468 - Set socket_error to errno if connecting fails in rfc2553_connect_to().
1469 Previously rejected direct connections could be incorrectly reported
1470 as DNS issues if Privoxy was compiled with IPv6 support.
1471 - Adjust url_code_map[] so spaces are replaced with %20 instead of '+'
1472 While '+' can be used by client's submitting form data, this is not
1473 actually what Privoxy is using the lookups for. This is more of a
1474 cosmetic issue and doesn't fix any known problems.
1475 - When compiled without FEATURE_FAST_REDIRECTS, do not silently
1476 ignore +fast-redirect{} directives
1477 - Added a workaround for GNU libc's strptime() reporting negative
1478 year values when the parsed year is only specified with two digits.
1479 On affected systems cookies with such a date would not be turned
1480 into session cookies by the +session-cookies-only action.
1481 Reported by Vaeinoe in #3403560
1482 - Fixed bind failures with certain GNU libc versions if no non-loopback
1483 IP address has been configured on the system. This is mainly an issue
1484 if the system is using DHCP and Privoxy is started before the network
1485 is completely configured.
1486 Reported by Raphael Marichez in #3349356.
1487 Additional insight from Petr Pisar.
1488 - Privoxy log messages now use the ISO 8601 date format %Y-%m-%d.
1489 It's only slightly longer than the old format, but contains
1490 the full date including the year and allows sorting by date
1491 (when grepping in multiple log files) without hassle.
1492 - In get_last_url(), do not bother trying to decode URLs that do
1493 not contain at least one '%' sign. It reduces the log noise and
1494 a number of unnecessary memory allocations.
1495 - In case of SOCKS5 failures, dump the socks response in the log message.
1496 - Simplify the signal setup in main().
1497 - Streamline socks5_connect() slightly.
1498 - In socks5_connect(), require a complete socks response from the server.
1499 Previously Privoxy didn't care how much data the server response
1500 contained as long as the first two bytes contained the expected
1501 values. While at it, shrink the buffer size so Privoxy can't read
1502 more than a whole socks response.
1503 - In chat(), do not bother to generate a client request in case of
1504 direct CONNECT requests. It will not be used anyway.
1505 - Reduce server_last_modified()'s stack size.
1506 - Shorten get_http_time() by using strftime().
1507 - Constify the known_http_methods pointers in unknown_method().
1508 - Constify the time_formats pointers in parse_header_time().
1509 - Constify the formerly_valid_actions pointers in action_used_to_be_valid().
1510 - Introduce a GNUMakefile MAN_PAGE variable that defaults to privoxy.1.
1511 The Debian package uses section 8 for the man page and this
1512 should simplify the patch.
1513 - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
1514 - In block_url(), ditch the obsolete workaround for ancient Netscape versions
1515 that supposedly couldn't properly deal with status code 403.
1516 - Remove a useless NULL pointer check in load_trustfile().
1517 - Remove two useless NULL pointer checks in load_one_re_filterfile().
1518 - Change url_code_map[] from an array of pointers to an array of arrays
1519 It removes an unnecessary layer of indirection and on 64bit system reduces
1520 the size of the binary a bit.
1521 - Fix various typos. Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
1522 - Add a dok-tidy GNUMakefile target to clean up the messy HTML
1523 generated by the other dok targets.
1524 - GNUisms in the GNUMakefile have been removed.
1525 - Change the HTTP version in static responses to 1.1
1526 - Synced config.sub and config.guess with upstream
1527 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
1528 - Add a dedicated function to parse the values of toggles. Reduces duplicated
1529 code in load_config() and provides better error handling. Invalid or missing
1530 toggle values are now a fatal error instead of being silently ignored.
1531 - Terminate HTML lines in static error messages with \n instead of \r\n.
1532 - Simplify cgi_error_unknown() a bit.
1533 - In LogPutString(), don't bother looking at pszText when not
1534 actually logging anything.
1535 - Change ssplit()'s fourth parameter from int to size_t.
1536 Fixes a clang complaint.
1537 - Add a warning that the statistics currently can't be trusted.
1538 Mention Privoxy-Log-Parser's --statistics option as
1539 an alternative for the time being.
1540 - In rfc2553_connect_to(), start setting cgi->error_message on error.
1541 - Change the expected status code returned for http://p.p/die depending
1542 on whether or not FEATURE_GRACEFUL_TERMINATION is available.
1543 - In cgi_die(), mark the client connection for closing.
1544 If the client will fetch the style sheet through another connection
1545 it gets the main thread out of the accept() state and should thus
1546 trigger the actual shutdown.
1547 - Add a proper CGI message for cgi_die().
1548 - Don't enforce a logical line length limit in read_config_line().
1549 - Slightly refactor server_last_modified() to remove useless gmtime*() calls.
1550 - In get_content_type(), also recognize '.jpeg' as JPEG extension.
1551 - Add '.png' to the list of recognized file extensions in get_content_type().
1552 - In block_url(), consistently use the block reason "Request blocked by Privoxy"
1553 In two places the reason was "Request for blocked URL" which hides the
1554 fact that the request got blocked by Privoxy and isn't necessarily
1555 correct as the block may be due to tags.
1556 - In listen_loop(), reload the configuration files after accepting
1557 a new connection instead of before.
1558 Previously the first connection that arrived after a configuration
1559 change would still be handled with the old configuration.
1560 - In chat()'s receive-data loop, skip a client socket check if
1561 the socket will be written to right away anyway. This can
1562 increase the transfer speed for unfiltered content on fast
1563 network connections.
1564 - The socket timeout is used for SOCKS negotiations as well which
1565 previously couldn't timeout.
1566 - Don't keep the client connection alive if any configuration file
1567 changed since the time the connection came in. This is closer to
1568 Privoxy's behaviour before keep-alive support for client connection
1569 has been added and also less confusing in general.
1570 - Treat all Content-Type header values containing the pattern
1571 'script' as a sign of text. Reported by pribog in #3134970.
1573 - Action file improvements:
1574 - Moved the site-specific block pattern section below the one for the
1575 generic patterns so for requests that are matched in both, the block
1576 reason for the domain is shown which is usually more useful than showing
1577 the one for the generic pattern.
1578 - Remove -prevent-compression from the fragile alias. It's no longer
1579 used anywhere by default and isn't known to break stuff anyway.
1580 - Add a (disabled) section to block various Facebook tracking URLs.
1581 Reported by Dan Stahlke in #3421764.
1582 - Add a (disabled) section to rewrite and redirect click-tracking
1583 URLs used on news.google.com.
1584 Reported by Dan Stahlke in #3421755.
1585 - Unblock linuxcounter.net/.
1586 Reported by Dan Stahlke in #3422612.
1587 - Block 'www91.intel.com/' which is used by Omniture.
1588 Reported by Adam Piggott in #3167370.
1589 - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
1590 Reminded by tceverling in #2790091.
1591 - Add ".ivwbox.de/" to the "Cross-site user tracking" section.
1592 Reported by Nettozahler in #3172525.
1593 - Unblock and fast-redirect ".awin1.com/.*=http://".
1594 Reported by Adam Piggott in #3170921.
1595 - Block "b.collective-media.net/".
1596 - Widen the Debian popcon exception to "qa.debian.org/popcon".
1597 Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
1598 - Block ".gemius.pl/" which only seems to be used for user tracking.
1599 Reported by johnd16 in #3002731. Additional input from Lee and movax.
1600 - Disable banners-by-size filters for '.thinkgeek.com/'.
1601 The filter only seems to catch pictures of the inventory.
1602 - Block requests for 'go.idmnet.bbelements.com/please/showit/'.
1603 Reported by kacperdominik in #3372959.
1604 - Unblock adainitiative.org/.
1605 - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'.
1606 - Add a fast-redirects exception for webcache.googleusercontent.com/.
1607 - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/.
1609 - Filter file improvements:
1610 - Let the yahoo filter hide '.ads'.
1611 - Let the msn filter hide overlay ads for Facebook 'likes' in search
1612 results and elements with the id 's_notf_div'. They only seem to be
1613 used to advertise site 'enhancements'.
1614 - Let the js-events filter additionally disarm setInterval().
1615 Suggested by dg1727 in #3423775.
1617 - Documentation improvements:
1618 - Clarify the effect of compiling Privoxy with zlib support.
1619 Suggested by dg1727 in #3423782.
1620 - Point out that the SourceForge messaging system works like a black
1621 hole and should thus not be used to contact individual developers.
1622 - Mention some of the problems one can experience when not explicitly
1623 configuring an IP addresses as listen address.
1624 - Explicitly mention that hostnames can be used instead of IP addresses
1625 for the listen-address, that only the first address returned will be
1626 used and what happens if the address is invalid.
1627 Requested by Calestyo in #3302213.
1629 - Log message improvements:
1630 - If only the server connection is kept alive, do not pretend to
1631 wait for a new client request.
1632 - Remove a superfluous log message in forget_connection().
1633 - In chat(), properly report missing server responses as such
1634 instead of calling them empty.
1635 - In forwarded_connect(), fix a log message nobody should ever see.
1636 - Fix a log message in socks5_connect(), a failed write operation
1637 was logged as failed read operation.
1638 - Let load_one_actions_file() properly complain about a missing
1639 '{' at the beginning of the file.
1640 Simply stating that a line is invalid isn't particularly helpful.
1641 - Do not claim to listen on a socket until Privoxy actually does.
1642 Patch submitted by Petr Pisar #3354485
1643 - Prevent a duplicated LOG_LEVEL_CLF message when sending out
1644 the "no-server-data" response.
1645 - Also log the client socket when dropping a connection.
1646 - Include the destination host in the 'Request ... marked for
1647 blocking. limit-connect{...} doesn't allow CONNECT ...' message
1648 Patch submitted by Saperski in #3296250.
1649 - Prevent a duplicated log message if none of the resolved IP
1650 addresses were reachable.
1651 - In connect_to(), do not pretend to retry if forwarded-connect-retries
1653 - When a specified user or group can't be found, put the name in
1654 single-quotes when logging it.
1655 - In rfc2553_connect_to(), explain getnameinfo() errors better.
1656 - Remove a useless log message in chat().
1657 - When retrying to connect, also log the maximum number of connection
1659 - Rephrase a log message in compile_dynamic_pcrs_job_list().
1660 Divide the error code and its meaning with a colon. Call the pcrs
1661 job dynamic and not the filter. Filters may contain dynamic and
1662 non-dynamic pcrs jobs at the same time. Only mention the name of
1663 the filter or tagger, but don't claim it's a filter when it could
1665 - In a fatal error message in load_one_actions_file(), cover both
1666 URL and TAG patterns.
1667 - In pcrs_strerror(), properly report unknown positive error code
1668 values as such. Previously they were handled like 0 (no error).
1669 - In compile_dynamic_pcrs_job_list(), also log the actual error code as
1670 pcrs_strerror() doesn't handle all errors reported by pcre.
1671 - Don't bother trying to continue chatting if the client didn't ask for it.
1672 Reduces log noise a bit.
1673 - Make two fatal error message in load_one_actions_file() more descriptive.
1674 - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'.
1675 - In load_file(), log a message if opening a file failed.
1676 The CGI error message alone isn't too helpful.
1677 - In connection_destination_matches(), improve two log messages
1678 to help understand why the destinations don't match.
1679 - Rephrase a log message in serve(). Client request arrival
1680 should be differentiated from closed client connections now.
1681 - In serve(), log if a client connection isn't reused due to a
1682 configuration file change.
1683 - Let mark_server_socket_tainted() always mark the server socket tainted,
1684 just don't talk about it in cases where it has no effect. It doesn't change
1685 Privoxy's behaviour, but makes understanding the log file easier.
1688 - Added a --disable-ipv6-support switch for platforms where support
1689 is detected but doesn't actually work.
1690 - Do not check for the existence of strerror() and memmove() twice
1691 - Remove a useless test for setpgrp(2). Privoxy doesn't need it and
1692 it can cause problems when cross-compiling.
1693 - Rename the --disable-acl-files switch to --disable-acl-support.
1694 Since about 2001, ACL directives are specified in the standard
1696 - Update the URL of the 'Removing outdated PCRE version after the
1697 next stable release' posting. The old URL stopped working after
1698 one of SF's recent site "optimizations". Reported by Han Liu.
1700 - Privoxy-Regression-Test:
1701 - Added --shuffle-tests option to increase the chances of detection race conditions.
1702 - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy.
1703 - Added tests for missing socks4 and socks4a forwarders.
1704 - The --privoxy-address option now works with IPv6 addresses containing brackets, too.
1705 - Perform limited sanity checks for parameters that are supposed to have numerical values.
1706 - Added a --sleep-time option to specify a number of seconds to
1707 sleep between tests, defaults to 0.
1708 - Disable the range-requests tagger for tests that break if it's enabled.
1709 - Log messages use the ISO 8601 date format %Y-%m-%d.
1710 - Fix spelling in two error messages.
1711 - In the --help output, include a list of supported tests and their default levels.
1712 - Adjust the tests to properly deal with FEATURE_TOGGLE being disabled.
1714 - Privoxy-Log-Parser:
1715 - Perform limited sanity checks for command line parameters that
1716 are supposed to have numerical values.
1717 - Implement a --unbreak-lines-only option to try to revert MUA breakage.
1718 - Accept and highlight: Added header: Content-Encoding: deflate
1719 - Accept and highlight: Compressed content from 29258 to 8630 bytes.
1720 - Accept and highlight: Client request arrived in time on socket 21.
1721 - Highlight: Didn't receive data in time: a.fsdn.com:443
1722 - Accept log messages with ISO 8601 time stamps, too.
1725 - Bump generated Firefox version to 8.0.
1726 - Only randomize the release date if the new --randomize-release-date
1727 option is enabled. Firefox versions after 4 use a fixed date string
1730 *** Version 3.0.17 Stable ***
1732 - Fixed last-chunk-detection for responses where the body was small
1733 enough to be read with the headers, causing Privoxy to wait for the
1734 end of the content until the server closed the connection or the
1735 request timed out. Reported by "Karsten" in #3028326.
1736 - Responses with status code 204 weren't properly detected as body-less
1737 like RFC2616 mandates. Like the previous bug, this caused Privoxy to
1738 wait for the end of the content until the server closed the connection
1739 or the request timed out. Fixes #3022042 and #3025553, reported by a
1740 user with no visible name. Most likely also fixes a bunch of other
1741 AJAX-related problem reports that got closed in the past due to
1742 insufficient information and lack of feedback.
1743 - Fixed an ACL bug that made it impossible to build a blacklist.
1744 Usually the ACL directives are used in a whitelist, which worked
1745 as expected, but blacklisting is still useful for public proxies
1746 where one only needs to deny known abusers access.
1747 - Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
1748 network. This should make debugging various parsing issues a lot easier.
1749 - The IPv6 code is enabled by default on Windows versions that support it.
1750 Patch submitted by oCameLo in #2942729.
1751 - In mingw32 versions, the user.filter file is reachable through the
1752 GUI, just like default.filter is. Feature request 3040263.
1753 - Added the configure option --enable-large-file-support to set a few
1754 defines that are required by platforms like GNU/Linux to support files
1755 larger then 2GB. Mainly interesting for users without proper logfile
1757 - Logging with "debug 16" no longer stops at the first nul byte which is
1758 pretty useless. Non-printable characters are replaced with their hex value
1759 so the result can't span multiple lines making parsing them harder then
1761 - Privoxy logs when reading an action, filter or trust file.
1762 - Fixed incorrect regression test markup which caused a test in
1763 3.0.16 to fail while Privoxy itself was working correctly.
1764 While Privoxy accepts hide-referer, too, the action name is actually
1765 hide-referrer which is also the name used one the final results page,
1766 where the test expected the alias.
1768 - CGI interface improvements:
1769 - In finish_http_response(), continue to add the 'Connection: close'
1770 header if the client connection will not be kept alive.
1771 Anonymously pointed out in #2987454.
1772 - Apostrophes in block messages no longer cause parse errors
1773 when the blocked page is viewed with JavaScript enabled.
1774 Reported by dg1727 in #3062296.
1775 - Fix a bunch of anchors that used underscores instead of dashes.
1776 - Allow to keep the client connection alive after crunching the previous request.
1777 Already opened server connections can be kept alive, too.
1778 - In cgi_show_url_info(), don't forget to prefix URLs that only contain
1779 http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott.
1780 - Show the 404 CGI page if cgi_send_user_manual() is called while
1781 local user manual delivery is disabled.
1783 - Action file improvements:
1784 - Enable user.filter by default. Suggested by David White in #3001830.
1785 - Block .sitestat.com/. Reported by johnd16 in #3002725.
1786 - Block .atemda.com/. Reported by johnd16 in #3002723.
1787 - Block js.adlink.net/. Reported by johnd16 in #3002720.
1788 - Block .analytics.yahoo.com/. Reported by johnd16 in #3002713.
1789 - Block sb.scorecardresearch.com, too. Reported by dg1727 in #2992652.
1790 - Fix problems noticed on Yahoo mail and news pages.
1791 - Remove the too broad yahoo section, only keeping the
1792 fast-redirects exception as discussed on ijbswa-devel@.
1793 - Don't block adesklets.sourceforge.net. Reported in #2974204.
1794 - Block chartbeat ping tracking. Reported in #2975895.
1795 - Tag CSS and image requests with cautious and medium settings, too.
1796 - Don't handle view.atdmt.com as image. It's used for click-throughs
1797 so users should be able to "go there anyway".
1798 Reported by Adam Piggott in #2975927.
1799 - Also let the refresh-tags filter remove invalid refresh tags where
1800 the 'url=' part is missing. Anonymously reported in #2986382.
1801 While at it, update the description to mention the fact that only
1802 refresh tags with refresh times above 9 seconds are covered.
1803 - javascript needs to be blocked with +handle-as-empty-document to
1804 work around Firefox bug 492459. So move .js blockers from
1805 +block{Might be a web-bug.} -handle-as-empty-document to
1806 +block{Might be a web-bug.} +handle-as-empty-document.
1807 - ijbswa-Feature Requests-3006719 - Block 160x578 Banners.
1808 - Block another omniture tracking domain.
1809 - Added a range-requests tagger.
1810 - Added two sections to get Flickr's Ajax interface working with
1811 default pre-settings. If you change the configuration to block
1812 cookies by default, you'll need additional exceptions.
1813 Reported by Mathias Homann in #3101419 and by Patrick on ijbswa-users@.
1815 - Documentation improvements:
1816 - Explicitly mention how to match all URLs.
1817 - Consistently recommend socks5 in the Tor FAQ entry and mention
1818 its advantage compared to socks4a. Reported by David in #2960129.
1819 - Slightly improve the explanation of why filtering may appear
1821 - Grammar fixes for the ACL section.
1822 - Fixed a link to the 'intercepting' entry and add another one.
1823 - Rename the 'Other' section to 'Mailing Lists' and reword it
1824 to make it clear that nobody is forced to use the trackers
1825 - Note that 'anonymously' posting on the trackers may not always
1827 - Suggest to enable debug 32768 when suspecting parsing problems.
1829 - Privoxy-Log-Parser improvements:
1830 - Gather statistics for ressources, methods, and HTTP versions
1832 - Also gather statistics for blocked and redirected requests.
1833 - Provide the percentage of keep-alive offers the client accepted.
1834 - Add a --url-statistics-threshold option.
1835 - Add a --host-statistics-threshold option to also gather
1836 statistics about how many request where made per host.
1837 - Fix a bug in handle_loglevel_header() where a 'scan: ' got lost.
1838 - Add a --shorten-thread-ids option to replace the thread id with
1840 - Accept and ignore: Looks like we got the last chunk together
1841 with the server headers. We better stop reading.
1842 - Accept and ignore: Continue hack in da house.
1843 - Accept and higlight: Rejecting connection from 10.0.0.2.
1844 Maximum number of connections reached.
1845 - Accept and highlight: Loading actions file: /usr/local/etc/privoxy/default.action
1846 - Accept and highlight: Loading filter file: /usr/local/etc/privoxy/default.filter
1847 - Accept and highlight: Killed all-caps Host header line: HOST: bestproxydb.com
1848 - Accept and highlight: Reducing expected bytes to 0. Marking
1849 the server socket tainted after throwing 4 bytes away.
1850 - Accept: Merged multiple header lines to: 'X-FORWARDED-PROTO: http X-HOST: 127.0.0.1'
1853 - Remove the next member from the client_state struct. Only the main
1854 thread needs access to all client states so give it its own struct.
1855 - Garbage-collect request_contains_null_bytes().
1856 - Ditch redundant code in unload_configfile().
1857 - Ditch LogGetURLUnderCursor() which doesn't seem to be used anywhere.
1858 - In write_socket(), remove the write-only variable write_len in
1859 an ifdef __OS2__ block. Spotted by cppcheck.
1860 - In connect_to(), don't declare the variable 'flags' on OS/2 where
1861 it isn't used. Spotted by cppcheck.
1862 - Limit the scope of various variables. Spotted by cppcheck.
1863 - In add_to_iob(), turn an interestingly looking for loop into a
1865 - Code cleanup in preparation for external filters.
1866 - In listen_loop(), mention the socket on which we accepted the
1867 connection, not just the source IP address.
1868 - In write_socket(), also log the socket we're writing to.
1869 - In log_error(), assert that escaped characters get logged
1870 completely or not at all.
1871 - In log_error(), assert that ival and sval have reasonable values.
1872 There's no reason not to abort() if they don't.
1873 - Remove an incorrect cgi_error_unknown() call in a
1874 cannot-happen-situation in send_crunch_response().
1875 - Clean up white-space in http_response definition and
1876 move the crunch_reason to the beginning.
1877 - Turn http_response.reason into an enum and rename it
1878 to http_response.crunch_reason.
1879 - Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686 GNU/Linux.
1880 - Fix white-space in a log message in remove_chunked_transfer_coding().
1881 While at it, add a note that the message doesn't seem to
1882 be entirely correct and should be improved later on.
1884 - GNUmakefile improvements:
1885 - Use $(SSH) instead of ssh, so one only needs to specify a username once.
1886 - Removed references to the action feedback thingy that hasn't been
1888 - Consistently use shell.sourceforge.net instead of shell.sf.net so
1889 one doesn't need to check server fingerprints twice.
1890 - Removed GNUisms in the webserver and webactions targets so they
1891 work with standard tar.
1893 *** Version 3.0.16 Stable ***
1895 - Added the config file option handle-as-empty-doc-returns-ok to
1896 work around Firefox bug #492459, which causes Firefox to hang
1897 if JavaScripts are blocked in certain situations. The option is
1898 enabled in the default config file.
1899 - Added the config file option default-server-timeout to control the
1900 assumed default server timeout. Since Privoxy no longer returns
1901 an error message for connection resets on reused client connections,
1902 assuming larger server timeout values appears to actually work
1903 pretty well as long as connections aren't shared.
1904 - Added optional support for FreeBSD's accf_http(9). Use the
1905 configure option --enable-accept-filter to enable it.
1906 - Added fancier Privoxy icons for win32. Contributed by Jeff H.
1907 - In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
1908 - Resolve localhost using whatever address family the operating
1909 system feels like. Previous betas would try to use IPv4 as this
1910 is what most users expect, but this didn't work reliably on
1912 - In the action lists on CGI pages, actions and their parameters are
1913 no longer separated with a space. The action file parser doesn't
1914 actually allow this and will throw an invalid syntax error if actions
1915 and parameters in the action files are separated. Not adding the
1916 spaces means copy and pasting CGI output into the action files works.
1917 - The default keep-alive timeout has been reduced to 5 seconds to work
1918 around hangs in clients that treat the proxy like any other host and
1919 stop allowing any new connections if the "maximum number of
1920 connections per host" is reached.
1921 - Several webbug URLs that look like they are leading to images are now
1922 blocked as image instead of empty documents. Doing the latter causes
1923 WebKit-based clients to show a "missing image" icon which may mess up
1925 - The no-such-domain template is used for DNS resolution
1926 problems with FEATURE_IPV6_SUPPORT enabled. Previously the
1927 connect-failed template was used. Reported by 'zebul666'.
1928 - Accepts quoted expiration dates even though RFC 2109 10.1.2
1929 doesn't seem to allow them. Reported anonymously.
1930 - Don't try to forget connections if connection sharing is disabled.
1931 This wasn't a real problem but caused an unnecessary log message.
1932 - The still undocumented --enable-extended-host-patterns configure
1933 option has a better description.
1934 - Fixed an error message that would claim a write to the server
1935 failed when actually writing to the client failed.
1936 - Log the crunch reason before trying to write to the client.
1937 The log is easier to read that way.
1938 - Several log messages about client connections also mention
1940 - handle-as-empty-document no longer depends on the image blocking
1942 - Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
1943 - uagen, a Firefox User-Agent generator for Privoxy and Mozilla
1944 browsers has been imported and is available in the tarball's
1946 - The scripts in the tools directory treat unknown parameters
1949 *** Version 3.0.15 beta ***
1951 - In case of missing server data, no error message is send to the
1952 client if the request arrived on a reused connection. The client
1953 is then supposed to silently retry the request without bothering
1954 the user. This should significantly reduce the frequency of the
1955 "No server or forwarder data received" error message many users
1957 - More reliable detection of prematurely closed client sockets
1958 with keep-alive enabled.
1959 - FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
1960 FEATURE_CONNECTION_SHARING and now available on
1962 - Improved handling of POST requests on reused connections.
1963 Should fix problems with stalled connections after submitting
1964 form data with some browser configurations.
1965 - Fixed various latency calculation issues.
1966 - Allows the client to pass NTLM authentication requests to a
1967 forwarding proxy. This was already assumed and hinted to work
1968 in 3.0.13 beta but actually didn't. Now it's confirmed to work
1969 with IE, Firefox and Chrome.
1970 Thanks to Francois Botha and Wan-Teh Chang
1971 - Fixed a calculation problem if receiving the server headers
1972 takes more than two reads, that could cause Privoxy to terminate
1973 the connection prematurely. Reported by Oliver.
1974 - Compiles again on platforms such as OpenBSD and systems
1975 using earlier glibc version that don't support AI_ADDRCONFIG.
1976 Anonymously submitted in #2872591.
1977 - A bunch of MS VC project files and Suse and Redhat RPM spec
1978 files have been removed as they were no longer maintained for
1980 - Overly long action lines are properly rejected with a proper
1981 error message. Previously they would be either rejected as
1982 invalid or cause a core dump through abort().
1983 - Already timed-out connections are no longer temporarily remembered.
1984 They weren't reused anyway, but wasted a socket slot.
1985 - len refers to the number of bytes actually read which might
1986 differ from the ones received. Adjust log messages accordingly.
1987 - The optional JavaScript on the CGI page uses encodeURIComponent()
1988 instead of escape() which doesn't encode all characters that matter.
1989 Anonymously reported in #2832722.
1990 - Fix gcc45 warnings in decompress_iob().
1991 - Various log message improvements.
1992 - Privoxy-Regression-Test supports redirect tests.
1993 - Privoxy-Log-Parser can gather some connection statistics.
1995 *** Version 3.0.14 beta ***
1997 - The latency is taken into account when evaluating whether or not to
1998 reuse a connection. This should significantly reduce the number of
1999 connections problems several users reported.
2000 - If the server doesn't specify how long the connection stays alive,
2001 Privoxy errs on the safe side of caution and assumes it's only a second.
2002 - The error pages for connection timeouts or missing server data use a
2003 Last-Modified date in the past. Retry attempts are detected and Privoxy
2004 removes the If-Modified-Since header to prevent the server from responding
2005 with status code 304 in which case the client would reuse the error message.
2006 - Setting keep-alive-timeout to 0 disables keep-alive support. Previously
2007 Privoxy would claim to allow persistence but not reuse the connection.
2008 - Pipelined requests are less likely to be mistaken for the request
2009 body of the previous request. Note that Privoxy still has no real
2010 pipeline support and will either serialize pipelined requests or
2011 drop them in which case the client has to resent them.
2012 - Fixed a crash on some Windows versions when header randomization
2013 is enabled and the date couldn't be parsed.
2014 - Privoxy's keep-alive timeout for the current connection is reduced
2015 to the one specified in the client's Keep-Alive header.
2016 - For HTTP/1.1 requests, Privoxy implies keep-alive support by not
2017 setting any Connection header instead of using 'Connection: keep-alive'.
2018 - If the socket isn't reusable, Privoxy doesn't temporarily waste
2019 a socket slot to remember the connection.
2020 - If keep-alive support is disabled but compiled in, the client's
2021 Keep-Alive header is removed.
2022 - Fixed a bug on mingw32 where downloading large files failed if
2023 keep-alive support was enabled.
2024 - Fixed a bug that (at least theoretically) could cause log
2025 timestamps to be occasionally off by about a second.
2026 - No Proxy-Connection header if added if there already is one.
2027 - The configure script respects the $PATH variable when searching
2030 *** Version 3.0.13 beta ***
2032 - Added IPv6 support. Thanks to Petr Pisar who not only provided
2033 the initial patch but also helped a lot with the integration.
2034 - Added client-side keep-alive support.
2035 - The connection sharing code is only used if the connection-sharing
2037 - The max-client-connections option has been added to restrict
2038 the number of client connections below a value enforced by
2039 the operating system.
2040 - Fixed a regression reintroduced in 3.0.12 that could cause
2041 crashes on mingw32 if header date randomization was enabled.
2042 - Compressed content with extra fields couldn't be decompressed
2043 and would get passed to the client unfiltered. This problem
2044 has only be detected through statical analysis with clang as
2045 nobody seems to be using extra fields anyway.
2046 - If the server resets the Connection after sending only the headers
2047 Privoxy forwards what it got to the client. Previously Privoxy
2048 would deliver an error message instead.
2049 - Error messages in case of connection timeouts use the right
2051 - If spawning a child to handle a request fails, the client
2052 gets an error message and Privoxy continues to listen for
2053 new requests right away.
2054 - The error messages in case of server-connection timeouts or
2055 prematurely closed server connections are now template-based.
2056 - If zlib support isn't compiled in, Privoxy no longer tries to
2057 filter compressed content unless explicitly asked to do so.
2058 - In case of connections that are denied based on ACL directives,
2059 the memory used for the client IP is no longer leaked.
2060 - Fixed another small memory leak if the client request times out
2061 while waiting for client headers other than the request line.
2062 - The client socket is kept open until the server socket has
2063 been marked as unused. This should increase the chances that
2064 the still-open connection will be reused for the client's next
2065 request to the same destination. Note that this only matters
2066 if connection-sharing is enabled.
2067 - A TODO list has been added to the source tarball to give potential
2068 volunteers a better idea of what the current goals are. Donations
2069 are still welcome too: https://www.privoxy.org/faq/general.html#DONATE
2071 *** Version 3.0.12 ***
2073 - The socket-timeout option now also works on platforms whose
2074 select() implementation modifies the timeout structure.
2075 Previously the timeout was triggered even if the connection
2076 didn't stall. Reported by cyberpatrol.
2077 - The Connection: keep-alive code properly deals with files
2078 larger than 2GB. Previously the connection was closed too
2080 - The content length for files above 2GB is logged correctly.
2081 - The user-manual directive on the show-status page links to
2082 the documentation location specified with the directive,
2083 not to the Privoxy website.
2084 - When running in daemon mode, Privoxy doesn't log anything
2085 to the console unless there are errors before the logfile
2087 - The show-status page prints warnings about invalid directives
2088 on the same line as the directives themselves.
2089 - Fixed several justified (but harmless) compiler warnings,
2090 mostly on 64 bit platforms.
2091 - The mingw32 version explicitly requests the default charset
2092 to prevent display problems with some fonts available on more
2093 recent Windows versions. Patch by Burberry.
2094 - The mingw32 version uses the Privoxy icon in the alt-tab
2095 windows. Patch by Burberry.
2096 - The timestamp and the thread id is omitted in the "Fatal error"
2097 message box on mingw32.
2098 - Fixed two related mingw32-only buffer overflows. Triggering
2099 them required control over the configuration file, therefore
2100 this isn't seen as a security issue.
2101 - In verbose mode, or if the new option --show-skipped-tests
2102 is used, Privoxy-Regression-Test logs skipped tests and the
2105 *** Version 3.0.11 ***
2107 - On most platforms, outgoing connections can be kept alive and
2108 reused if the server supports it. Whether or not this improves
2109 things depends on the connection.
2110 - When dropping privileges, membership in supplementary groups
2111 is given up as well. Not doing that can lead to Privoxy running
2112 with more rights than necessary and violates the principle of
2113 least privilege. Users of the --user option are advised to update.
2114 Thanks to Matthias Drochner for reporting the problem,
2115 providing the initial patch and testing the final version.
2116 - Passing invalid users or groups with the --user option
2117 didn't lead to program exit. Regression introduced in 3.0.7.
2118 - The match all section has been moved from default.action
2119 to a new file called match-all.action. As a result the
2120 default.action no longer needs to be touched by the user
2121 and can be safely overwritten by updates.
2122 - The standard.action file has been removed. Its content
2123 is now part of the default.action file.
2124 - In some situations the logged content length was slightly too low.
2125 - Crunched requests are logged with their own log level.
2126 If you used "debug 1" in the past, you'll probably want
2127 to additionally enable "debug 1024", otherwise only passed
2128 requests will be logged. If you only care about crunched
2129 requests, simply replace "debug 1" with "debug 1024".
2130 - The crunch reason has been moved to the beginning of the
2131 crunch message. For HTTP URLs, the protocol is logged as well.
2132 - Log messages are shortened by printing the thread id on its
2133 own (as opposed to putting it inside the string "Privoxy()").
2134 - The config option socket-timeout has been added to control
2135 the time Privoxy waits for data to arrive on a socket.
2136 - Support for remote toggling is controlled by the configure
2137 option --disable-toggle only. In previous versions it also
2138 depended on the action editor and thus configuring with the
2139 --disable-editor option would disable remote toggling support
2141 - Requests with invalid HTTP versions are rejected.
2142 - The template symbol @date@ can be used to include a date(1)-like
2143 time string. Initial patch submitted by Endre Szabo.
2144 - Responses from shoutcast servers are accepted again.
2145 Problem reported and fix suggested by Stefan.
2146 - The hide-forwarded-for-headers action has been replaced with
2147 the change-x-forwarded-for{} action which can also be used to
2148 add X-Forwarded-For headers. The latter functionality already
2149 existed in Privoxy versions prior to 3.0.7 but has been removed
2150 as it was often used unintentionally (by not using the
2151 hide-forwarded-for-headers action).
2152 - A "clear log" view option was added to the mingw32 version
2153 to clear out all of the lines in the Privoxy log window.
2154 Based on a patch submitted by T Ford.
2155 - The mingw32 version uses "critical sections" now, which prevents
2156 log message corruption under load. As a side effect, the
2157 "no thread-safe PRNG" warning could be removed as well.
2158 - The mingw32 version's task bar icon is crossed out and
2159 the color changed to gray if Privoxy is toggled off.
2161 *** Version 3.0.10 ***
2163 - Ordinary configuration file changes no longer cause program
2164 termination on OS/2 if the name of the logfile hasn't been
2165 changed as well. This regression probably crept in with the
2166 logging improvements in 3.0.7. Reported by Maynard.
2167 - The img-reorder filter is less likely to mess up JavaScript code in
2168 img tags. Problem and solution reported by Glenn Washburn in #2014552.
2169 - The source tar ball now includes Privoxy-Log-Parser,
2170 a syntax-highlighter for Privoxy logs. For fancy screenshots see:
2171 http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
2172 Documentation is available through perldoc(1).
2174 *** Version 3.0.9 beta ***
2176 - Added SOCKS5 support (with address resolution done by
2177 the SOCKS5 server). Patch provided by Eric M. Hopper.
2178 - The "blocked" CGI pages include a block reason that was
2179 provided as argument to the last-applying block action.
2180 - If enable-edit-actions is disabled (the default since 3.0.7 beta)
2181 the show-status page hides the edit buttons and explains why.
2182 Previously the user would get the "this feature has been disabled"
2183 message after using the edit button.
2184 - Forbidden CONNECT requests are treated like blocks by default.
2185 The now-pointless treat-forbidden-connects-like-blocks action
2187 - Not enabling limit-connect now allows CONNECT requests to all ports.
2188 In previous versions it would only allow CONNECT requests to port 443.
2189 Use +limit-connect{443} if you think you need the old default behaviour.
2190 - The CGI editor gets turned off after three edit requests with invalid
2191 file modification timestamps. This makes life harder for attackers
2192 who can leverage browser bugs to send fake Referers and intend to
2193 brute-force edit URLs.
2194 - Action settings for multiple patterns in the same section are
2195 shared in memory. As a result these sections take up less space
2196 (and are loaded slightly faster). Problem reported by Franz Schwartau.
2197 - Linear white space in HTTP headers will be normalized to single
2198 spaces before parsing the header's content, headers split across
2199 multiple lines get merged first. This should prevent problems like:
2200 * letting the session-cookies-only action slip
2201 some Cookies through unmodified,
2202 * only suppressing the first line of a header,
2203 thus creating an invalid one, and
2204 * to incorrectly block headers with valid timestamps
2205 that weren't properly recognized.
2206 Headers that could trigger these problems are unlikely to appear
2207 in "normal" web traffic, but could be intentionally generated to
2208 fool some of Privoxy's header parsers.
2209 - Host information is gathered outside the main thread so it's less
2210 likely to delay other incoming connections if the host is misconfigured.
2211 - New config option "hostname" to use a hostname other than
2212 the one returned by the operating system. Useful to speed-up responses
2213 for CGI requests on misconfigured systems. Requested by Max Khon.
2214 - The CGI editor supports the "disable all filters of this type"
2215 directives "-client-header-filter", "-server-header-filter",
2216 "-client-header-tagger" and "-server-header-tagger".
2217 - Fixed false-positives with the link-by-url filter and URLs that
2218 contain the pattern "/jump/".
2219 - The less-download-windows filter no longer messes
2220 "Content-Type: application/x-shockwave-flash" headers up.
2221 - In the show-url-info page's "Final results" section active and
2222 inactive actions are listed separately. Patch provided by Lee.
2223 - The GNUmakefile supports the DESTDIR variable. Patch for
2224 the install target submitted by Radoslaw Zielinski.
2225 - Embedding the content of configuration files in the show-status
2226 page is significantly faster now. For a largish action file (1 MB)
2227 a speedup of about 2450 times has been measured. This is mostly
2228 interesting if you are using large action files or regularly use
2229 Privoxy-Regression-Test while running Privoxy through Valgrind,
2230 for stock configuration files it doesn't really matter.
2231 - If zlib support is unavailable and there are content
2232 filters active but the prevent-compression action is disabled,
2233 the show-url-info page includes a warning that compression
2234 might prevent filtering.
2235 - The show-url-info page provides an OpenSearch Description that
2236 allows to access the page through browser search plugins.
2237 - Custom client-header filters that rewrite the request line
2238 incorrectly no longer cause Privoxy to crash. Reported by din_a4.
2239 - The obsolete kill-popups action has been removed as the
2240 PCRS-based popup filters can do the same and are slightly
2242 - The inspect-jpegs action has been removed.
2243 - The send-wafer and send-vanilla-wafer actions have been removed.
2244 They weren't particular useful and their behaviour could be emulated
2245 with add-header anyway.
2246 - Privoxy-Regression-Test has been significantly improved.
2247 - Most sections in the default.action file contain tests for
2248 Privoxy-Regression-Test to verify that they are working as intended.
2249 - Parts of Privoxy have been refactored to increase maintainability.
2250 - Building with zlib (if available) is done by default.
2252 *** Version 3.0.8 ***
2254 - Fixed a small memory leak when listen-address only specifies the port.
2255 - The source tar balls now include Privoxy-Regression-Test which
2256 (upon other things) can be used to automatically detect some
2257 packaging problems. Packagers are welcome to give it a try.
2258 - Reverted a change in 3.0.7 that caused path patterns to be checked
2259 even if the host pattern match already failed. While this doesn't
2260 noticeable affect the performance, it makes it less likely to run
2261 out of stack space with overly-complex path patterns the user might
2263 - Updated the msn, yahoo and google filters to work as advertised again.
2264 - The warning message shown by the show-status CGI page is easier to
2265 understand. Previously it wasn't clear that the error message
2266 is shown below the invalid directive. (Reported by Lee)
2267 - When regenerating Content-Disposition headers the more common
2268 spelling is used for the name. Previously it was written without caps.
2269 - Less confusing log message if the content type isn't overwritten
2270 because force-text-type wasn't used but the old type doesn't look
2271 like content that would be filtered normally.
2272 - Better log messages if the user tries to execute filters that
2274 - Treat the non-standard Request-Range headers like standard range
2275 headers and suppress them if content filtering is enabled.
2276 - Prevent the log messages for CONNECT requests to unacceptable
2277 ports from printing the limit-connect argument as [null] if
2278 limit-connect hasn't been explicitly enabled.
2279 - Don't disable the mingw32 log window if the logfile directive
2280 isn't used. While it was an intentional change in 3.0.7 at least
2281 one user perceived it as a regression and the same effect can
2282 be achieved by disabling all debug directives.
2283 - Fixed two minor problems related to the win32 build process: a css
2284 file was not being in the installer and the trustfile comment in the
2285 config.txt referenced a nonexisting file
2286 - Minor documentation fixes.
2288 *** Version 3.0.7 beta ***
2290 - Added zlib support to filter content with gzip and deflate
2291 encoding. (Patch provided by Wil Mahan)
2292 - Dedicated filters and actions are used for header filtering.
2293 "filter-client-headers" and "filter-client-headers" are no longer
2294 supported, use server-header-filter{} and client-header-filter{}
2296 - Tags can be used to change actions based on HTTP headers.
2297 - New server-header filter: less-download-windows.
2298 - New client-header taggers: css-requests, image-requests,
2299 client-ip-address, http-method, allow-post, complete-url,
2300 user-agent and privoxy-control.
2301 - New server-header taggers: content-type and privoxy-control.
2302 - The forward-override{} action allows to change the forwarding
2303 settings through the action files, for example based on client
2304 headers like the User-Agent, or the request origin.
2305 - Socks errors are no longer handled by the CGI page for
2306 DNS resolution failures.
2307 - CGI pages use favicons to signal whether they are error
2308 or control pages. This is useful if you rely heavily on
2310 - The show-url-info CGI page shows the forwarding settings.
2311 - "Crunch!" log messages (used when Privoxy answers requests
2312 by itself) now also contain the reason.
2313 - Allow to rewrite the request destination behind the client's back.
2314 - Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
2315 - Fixes possible deadlocks and crashes on OpenBSD.
2316 Patch provided by Ralf Horstmann.
2317 - The CGI action editor allows to edit actionfiles with previously
2318 forbidden characters like dots.
2319 - New trust entries are saved with a comment that contains the
2320 trusted referring URL (Suggested by Daniel Griscom).
2321 - Filter descriptions are HTML encoded automatically.
2322 - New config option "split-large-forms" to work
2323 around a browser bug that caused IE6 and IE7 to ignore
2324 the Submit button on the edit-actions-for-url CGI page.
2325 - New config option "allow-cgi-request-crunching" to allow
2326 requests for Privoxy's CGI pages to be blocked, redirected
2327 or (un)trusted like ordinary requests.
2328 - Empty filter files no longer interrupt the filtering process
2329 prematurely and are correctly listed on the show-status CGI page.
2330 - New config option "accept-intercepted-requests" to combine
2331 Privoxy with any packet filter to build an intercepting proxy
2332 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
2333 - fast-redirects{} catch redirects to https URLs as well.
2334 - redirect{s@foo@bar@} can be used to redirect to a rewritten
2335 version of the original URL.
2336 - Trap unsupported gopher proxy requests.
2337 - Fixed a bug in the User Manual delivery on Windows
2338 (mingw32 only). Images now show up correctly and HTML
2339 pages are no longer padded with garbage data.
2340 - Fixed several minor memory leaks, most of them discovered with Valgrind.
2341 - Only unlink the pidfile if it's actually used.
2342 - Retries after connection problems with forced requests
2343 aren't blocked again.
2344 - On Unix SIGABRT causes a core dump as expected and is no
2345 longer treated as normal shutdown signal.
2346 - The "access denied" CGI page is more descriptive and
2347 allows retries to circumvent the referrer check.
2348 - Updated PCRS to handle unexpected PCRE errors properly.
2349 Fixed crashes that could occur if Privoxy was build
2350 with external PCRE versions newer than Privoxy's internal
2351 one. (Reported by Chung-chieh Shan)
2352 - Fixed crashes with null bytes in PCRS replacement strings
2353 (Patch provided by Felix Gröbert).
2354 - Fixed crashes with header time randomization on mingw32.
2355 - The CGI style sheet is no longer delivered if the referring
2356 page isn't a Privoxy CGI page. This prevents a JavaScript-based
2357 Privoxy detection "attack". Note that detecting Privoxy is
2358 still possible through other ways and Privoxy was never intended
2359 to be invisible anyway.
2360 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
2361 - The show-url-info CGI page displays a warning if Privoxy
2362 is currently toggled off.
2363 - The show-status CGI page suppresses the edit button
2364 for action files if Privoxy has no write access.
2365 - Most CGI error pages react properly to HEAD requests.
2366 - Requests with RFC 3253 HTTP methods (used by Subversion)
2367 are accepted. (Patch provided by Petr Kadlec)
2368 - New config option "templdir" to change the location
2369 of the CGI templates to make sure customized templates
2371 - Better handling of "HTTP/1.1 100 Continue" responses.
2372 - The background of the PNG pattern is transparent.
2373 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
2374 - Fixed crashes and possible action file corruptions
2375 when lines containing hashes are written through the CGI editor.
2376 - Supports dynamic filters which can contain variables.
2377 - Supports tags to change the actions based on client or server headers.
2378 - Incorrect actions are logged before program termination.
2379 - The "actionsfile" syntax in the configuration file is consistent
2380 with the rest of the configuration options and requires the
2381 whole file name. This is an incompatible change, if you use
2382 an old configuration file you might have to append ".action"
2383 to your "actionsfile" directives.
2384 - With the configuration file option "enforce-blocks" the
2385 "go there anyway" mechanism can be disabled without recompiling
2387 - More precise error messages in case of incorrect acl syntax.
2388 - Logs a warning if filtering is enabled but impossible due
2389 to lack of zlib support or use of the prevent-compression action.
2390 - Less noisy handling of Cookie:" and "Connection:" headers.
2391 - Improved error messages in case of connection problems.
2392 - Fix a command-line-parsing bug that was introduced before 3.0.5
2393 beta and caused Privoxy to treat the last argument as configuration
2394 file if no configuration file was specified.
2395 - Treat unknown command line options as fatal errors instead
2396 of silently ignoring them.
2397 - Use string functions with length checks more often.
2398 - Don't log CONNECT requests twice.
2399 - Allow to log the source address for ACL-related connection drops.
2400 - Don't ignore applying filters if the server didn't
2401 specify a Content-Type. Bug reported by Amuro Namie.
2402 - Rejected CONNECT requests are logged with log level info
2403 (enabled by default) and the reason for the block.
2404 - New command line option "--pre-chroot-nslookup hostname" to
2405 intialize the resolver library before chroot'ing. On some systems this
2406 reduces the number of files that must be copied into the chroot tree.
2407 (Patch provided by Stephen Gildea)
2408 - Fix a long-standing memory corruption bug that could cause
2409 Privoxy to overwrite a single byte in memory it didn't explicitly
2410 allocate (but that probably was allocated anyway due to bucket size).
2411 - Send template-based CGI pages as HTTP/1.1 unless the client
2413 - Let the first line in connection established responses
2414 end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
2415 - If no log file has been specified, disable logging instead of logging
2417 - Don't block stderr when in daemon mode.
2418 - Ignore missing zero-chunks when filtering chunk-encoded content.
2419 Earlier Privoxy versions would buffer and then forward the content
2420 unmodified which caused some browsers to simply show empty pages.
2421 - Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
2422 - The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
2423 action isn't being used has been removed.
2424 - Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
2426 - Minor code clean-ups, filter and action file updates.
2427 (Some of them reported by Davide Alberani, Markus Elfring,
2428 Stefan Huehner and Adam Piggott)
2430 *** Version 3.0.6 ***
2432 - New content filters: no-ping, google, msn, yahoo and blogspot.
2433 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
2434 and hide-tor-exit-notation.
2435 - The special header "X-Filter: No" now disables header filtering as well.
2436 - Improved the filters img-reorder, js-annoyances, webbugs,
2437 banners-by-size, banners-by-link and ie-exploits to make them
2438 less likely to break anything.
2439 - Removed outdated URL patterns in default.action and added new ones.
2440 - Added redirection from http://p.p/user-manual to http://p.p/user-manual/
2441 - Changed webinterface default values for hide-user-agent, hide-referrer
2442 and set-image-blocker.
2444 *** Version 3.0.5 beta ***
2446 - Windows version can be installed/started as a service.
2447 - Windows icon stays blue when Privoxy is idle, green when busy.
2448 - Integrated Fabian Keil's extensive patch. See:
2449 http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
2450 following new or significantly improved actions (among many
2451 other improvements):
2453 content-type-overwrite{}
2454 crunch-client-header{string}
2455 crunch-if-none-match
2456 crunch-server-header{string}
2457 fast-redirects{check-decoded-url}
2458 filter-client-headers
2459 filter-server-headers
2461 handle-as-empty-document
2462 hide-accept-language{}
2463 hide-content-disposition{}
2464 hide-if-modified-since
2465 hide-referrer{conditional-block}
2466 overwrite-last-modified{}
2468 treat-forbidden-connects-like-blocks
2470 - Standard-compliant clients are prevented from displaying cached
2471 copies of Privoxy's error messages after the cause of the problem
2473 - Improved DNS error handling.
2474 - Multiple filter files can now be specified in config.
2475 - Added jpeg filtering to defend against MS jpeg vulnerability MS04-028
2476 with the new inspect-jpegs action.
2477 - Removed the "arbitrary" 1000 filter limit - addresses tracker #911950

2491 *** Version 3.0.3 ***
2493 - Fixed yet another two memory leaks. Process growth seems stopped now.
2494 - Further tightened security against malicious toggle-off links.
2495 - Excluded text/plain MIME types from filtering. This fixes a
2496 couple of client-crashing, download corruption and
2497 Privoxy performance issues, whose root cause lies in
2498 web servers labelling content of unknown type as text/plain.
2499 - Assorted fixes for POSIX compliance, signal handling, graceful
2500 termination, compiler warnings, OSX support, Win32 systray,
2501 error logging, hostname wildcards, correct detection of NetBSD.
2502 - Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs
2503 including the notorious "blank page" problem.

2520 html-annoyances, content-cookies and fun filters
2521 - Replaced filter "popups" by choice between two modes:
2522 - "unsolicited-popups" tries to catch only the unsolicited ones
2523 - "all-popups" tries to kill them all (as before)
2524 - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
2525 - New filter "jumping-windows" that prevents windows from resizing
2526 and moving themselves
2527 - New filter "demoronizer" which fixes MS's abuse of std charsets
2528 (common cases anyway).
2529 - Replaced "nimda" with more general "ie-exploits" filter in which
2530 all filters for exploits shall be collected
2531 - Improved cookie logging
2532 - Rewrote make install target. Added uninstall and install-strip
2534 - Fixed a potential (application-level, NOT OS-level!) security
2535 problem involving remote toggling and action file manipulation
2536 by mailicious websites.
2537 - Added ability to chroot (thanks to Sviatoslav Sviridov)

2585 - #include mechansim for common text in templates
2586 - Various other minor fixes.
2588 *** Version 2.9.13 beta ***
2590 - *NEWS*: The project has been renamed to Privoxy! The new name is
2591 reflected throughout (file locations, etc).
2592 - ijb.action is now default.action. re_filterfile is now
2594 - http://i.j.b/ is now http://p.p/

2623 - Fixes for actions cgi editor, make sure we have right file.
2624 - A --pidfile command line option now, in addition to --help,
2625 --version, --no-daemon, --user and configfile. --no-daemon replaces

2662 - Many other minor bugfixes
2663 - Start a ChangeLog :)
2667 *** Version 2.9.3 pre-Alpha Changes ***
2669 - Amiga support (completely untested by me - I don't have an Amiga)
2670 - "tinygif 3" support (redirects blocked images to a specified URL, so
2671 the browser doesn't have to load and cache many copies of the same
2673 - one case where there were both local and global "referrer" variables
2674 (yuck!) clarified by renaming the local one to "refer".
2675 - Fixed some places where close() was used instead of close_socket().
2676 Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
2677 - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
2678 FORCE_LOAD_PREFIX. Needs fixing properly.
2679 - Most URLs hardcoded into Junkbuster were changed to go through a script
2680 e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
2681 The only other URLs left are the GNU GPL:
2682 http://www.fsf.org/copyleft/gpl.html
2684 http://ijbswa.sourceforge.net/
2685 ... and various URLs which will be intercepted by Junkbuster anyway.
2686 TODO: Still need to do something with the URLs in Junkbuster Corp's
2687 copyright/trademark notice on the bottom of the show-proxy-args page.
2688 - PCRE or GNU Regex is now a #define option.
2691 *** Version 2.9.2 pre-Alpha Changes ***
2693 - Andreas applied the latest version of the FORCE patch.
2696 *** Version 2.9.1 pre-Alpha Changes ***
2698 - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
2699 (BTW: I think FORCE is precise enough, since loading remote
2700 data is the whole purpose of a proxy..)
2701 - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
2702 is more elegant and looks like a hostname in the URL, it doesn't
2703 make clear to the inexperienced user that the proxy is bypassed. It
2704 also has a higher name collision risk.
2705 - Filled in the function header templates for my functions in
2706 parsers.c (again). They obviously got lost in our current
2708 - Cut the credit for the §-referrer-option from the config file,
2709 that Stefan had placed there.
2710 - Improved the re_filterfile
2713 *** Version 2.9.0 pre-Alpha Changes ***
2715 - Now use PCRE, not GNU REGEX. I have not yet had chance to check the
2716 syntax of the block/image/cookie file to ensure that they match what
2717 is expected - however they seem to work.
2718 - Replaced "configure" script with one generated by "autoconf". Also
2719 use a header "config.h" (was ijbconfig.h in my previous release) for
2720 the #defines. "config.h" is now generated with "autoheader" from
2721 "acconfig.h" and "configure.in". (Note that to install you do not
2722 need autoconf or autoheader - just run "./configure".)
2723 To see command-line options, run "./configure --help".
2724 This is my first ever autoconf script, so it has some rough edges
2725 (how PCRE is handled is the roughest).
2726 - Error logging code replaced with new module errlog.c, based on the
2727 one from JunkbusterMT (but with the threading code removed).
2728 - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
2729 apply all of these, since I had already independently done conditional
2730 popup file, conditional image file, and integration of popup code.
2731 - ACL, Jar and trust files conditionally compiled.
2732 - New source file headers.
2733 - Various cosmetic changes. (But I have not consistently ordered the
2734 config files - I think that's worthwhile, but it's 1am and I want to
2736 - RCS tags on .h files.
2737 - RCS tags are const char[] rather than const char *. (Saves 4 bytes
2739 - VC++ project files renamed to vc_junkbuster.*.
2740 - show-proxy-args now shows status of all conditionals, not just REGEX
2741 - Various functions moved around. Most notably all the system-specific
2742 sockets code which was spread between jcc.c, bind.c, and connect.c,
2743 has been moved to "jbsockets.c". The non-system-specific code from
2744 connect.c and socks4.c has been movet to "gateway.c". Also, the
2745 config file loader and the global variables it writes to have been
2746 moved to "loadcfg.c". (Maybe this should go into loaders.c?)
2747 And candidate for the "worst filename ever" award is "miscutil.c",
2748 which contains, well, miscellaneous utility functions like zalloc.
2749 (Suggestions for a better name for this file are welcome!)
2750 - Loaders now use a common function to read a line and skip comments,
2751 and this function also stores the proxy_args.
2752 - Added ./junkbuster --help (Not for Win32 GUI)
2753 - Added ./junkbuster --version (Not for Win32 GUI)
2754 - Win32 resources are now all marked as "U.S. English", rather than
2755 being a mix of "U.S. English", "U.K. English" and "Irish English".
2756 - Version number changes to 2.9.0
