4 *** Version 3.0.21 stable ***
7 - On POSIX-like platforms, network sockets with file descriptor
8 values above FD_SETSIZE are properly rejected. Previously they
9 could cause memory corruption in configurations that allowed
10 the limit to be reached.
11 - Proxy authentication headers are removed unless the new directive
12 enable-proxy-authentication-forwarding is used. Forwarding the
13 headers potentionally allows malicious sites to trick the user
14 into providing it with login information.
15 Reported by Chris John Riley.
16 - Compiles on OS/2 again now that unistd.h is only included
17 on platforms that have it.
19 - General improvements:
20 - The show-status page shows the FEATURE_STRPTIME_SANITY_CHECKS status.
21 - A couple of assert()s that could theoretically dereference
22 NULL pointers in debug builds have been relocated.
23 - Added an LSB info block to the generic start script.
24 Based on a patch from Natxo Asenjo.
25 - The max-client-connections default has been changed to 128
26 which should be more than enough for most setups.
28 - Action file improvements:
29 - Block rover.ebay./ar.*\&adtype= instead of "/.*\&adtype=" which
30 caused too man false positives.
31 Reported by u302320 in #360284, additional feedback from Adam Piggott.
32 - Unblock '.advrider.com/' and '/.*ADVrider'.
33 Anonymously reported in #3603636.
34 - Stop blocking '/js/slider\.js'.
35 Reported by Adam Piggott in #3606635 and _lvm in #2791160.
37 - Filter file improvements:
38 - Added an iframes filter.
40 - Documentation improvements:
41 - The whole GPLv2 text is included in the user manual now,
42 so Privoxy can serve it itself and the user can read it
43 without having to wade through GPLv3 ads first.
44 - Properly numbered and underlined a couple of section titles
45 in the config that where previously overlooked due to a flaw
46 in the conversion script. Reported by Ralf Jungblut.
47 - Improved the support instruction to hopefully make it harder to
48 unintentionally provide insufficient information when requesting
49 support. Previously it wasn't obvious that the information we need
50 in bug reports is usually also required in support requests.
51 - Removed documentation about packages that haven't been provided
54 - Privoxy-Regression-Test:
55 - Only log the test number when not running in verbose mode
56 The position of the test is rarely relevant and it previously
57 wasn't exactly obvious which one of the numbers was useful to
58 repeat the test with --test-number.
60 - GNUmakefile improvements:
61 - Factor generate-config-file out of config-file to make testing
63 - The clean target now also takes care of patch leftovers.
65 *** Version 3.0.20 beta ***
68 - Client sockets are now properly shutdown and drained before being
69 closed. This fixes page truncation issues with clients that aggressively
70 pipeline data on platforms that otherwise discard already written data.
71 The issue mainly affected Opera users and was initially reported
72 by Kevin in #3464439, szotsaki provided additional information to track
74 - Fix latency calculation for shared connections (disabled by default).
75 It was broken since their introduction in 2009. The calculated latency
76 for most connections would be 0 in which case the timeout detection
77 failed to account for the real latency.
78 - Reject URLs with invalid port. Previously they were parsed incorrectly and
79 characters between the port number and the first slash were silently
80 dropped as shown by curl test 187.
81 - The default-server-timeout and socket-timeout directives accept 0 as
83 - Fix a race condition on Windows that could cause Privoxy to become
84 unresponsive after toggling it on or off through the taskbar icon.
85 Reported by Tim H. in #3525694.
86 - Fix the compilation on Windows when configured without IPv6 support.
87 - Fix an assertion that could cause debug builds to abort() in case of
88 socks5 connection failures with "debug 2" enabled.
89 - Fix an assertion that could cause debug builds to abort() if a filter
90 contained nul bytes in the replacement text.
92 - General improvements:
93 - Significantly improved keep-alive support for both client and server
95 - New debug log level 65536 which logs all actions that were applied to
97 - New directive client-header-order to forward client headers in a
98 different order than the one in which they arrived.
99 - New directive tolerate-pipelining to allow client-side pipelining.
100 If enabled (3.0.20 beta enables it by default), Privoxy will keep
101 pipelined client requests around to deal with them once the current
102 request has been served.
103 - New --config-test option to let Privoxy exit after checking whether or not
104 the configuration seems valid. The limitations noted in TODO #22 and #23
105 still apply. Based on a patch by Ramkumar Chinchani.
106 - New limit-cookie-lifetime{} action to let cookies expire before the end
107 of the session. Suggested by Rick Sykes in #1049575.
108 - Increase the hard-coded maximum number of actions and filter files from
109 10 to 30 (each). It doesn't significantly affect Privoxy's memory usage
110 and recompiling wasn't an option for all Privoxy users that reached the
112 - Add support for chunk-encoded client request bodies. Previously
113 chunk-encoded request bodies weren't guaranteed to be forwarded correctly,
114 so this can also be considered a bug fix although chunk-encoded request
115 bodies aren't commonly used in the real world.
116 - Add support for Tor's optimistic-data SOCKS extension, which can reduce the
117 latency for requests on newly created connections. Currently only the
118 headers are sent optimistically and only if the client request has already
119 been read completely which rules out requests with large bodies.
120 - After preventing the client from pipelining, don't signal keep-alive
121 intentions. When looking at the response headers alone, it previously
122 wasn't obvious from the client's perspective that no additional responses
124 - Stop considering client sockets tainted after receiving a request with body.
125 It hasn't been necessary for a while now and unnecessarily causes test
126 failures when using curl's test suite.
127 - Allow HTTP/1.0 clients to signal interest in keep-alive through the
128 Proxy-Connection header. While such client are rare in the real world, it
129 doesn't hurt and couple of curl tests rely on it.
130 - Only remove duplicated Content-Type headers when filters are enabled.
131 If they are not it doesn't cause ill effects and the user might not want it.
132 Downgrade the removal message to LOG_LEVEL_HEADER to clarify that it's not
133 an error in Privoxy and is unlikely to cause any problems in general.
134 Anonymously reported in #3599335.
135 - Set the socket option SO_LINGER for the client socket.
136 - Move several variable declarations to the beginning of their code block.
137 It's required when compiling with gcc 2.95 which is still used on some
138 platforms. Initial patch submitted by Simon South in #3564815.
139 - Optionally try to sanity-check strptime() results before trusting them.
140 Broken strptime() implementations have caused problems in the past and
141 the most recent offender seems to be FreeBSD's libc (standards/173421).
142 - When filtering is enabled, let Range headers pass if the range starts at
143 the beginning. This should work around (or at least reduce) the video
144 playback issues with various Apple clients as reported by Duc in #3426305.
145 - Do not confuse a client hanging up with a connection time out. If a client
146 closes its side of the connection without sending a request line, do not
147 send the CLIENT_CONNECTION_TIMEOUT_RESPONSE, but report the condition
149 - Allow closing curly braces as part of action values as long as they are
151 - On Windows, the logfile is now written before showing the GUI error
152 message which blocks until the user acknowledges it.
153 Reported by Adriaan in #3593603.
154 - Remove an unreasonable parameter limit in the CGI interface. The new
155 parameter limit depends on the memory available and is currently unlikely
156 to be reachable, due to other limits in both Privoxy and common clients.
157 Reported by Andrew on ijbswa-users@.
158 - Decrease the chances of parse failures after requests with unsupported
159 methods were sent to the CGI interface.
161 - Action file improvements:
162 - Remove the comment that indicated that updated default.action versions
163 are released on their own.
164 - Block 'optimize.indieclick.com/' and 'optimized-by.rubiconproject.com/'
165 - Unblock 'adjamblog.wordpress.com/' and 'adjamblog.files.wordpress.com/'.
166 Reported by Ryan Farmer in #3496116.

177 - Disable fast-redirects for '.googleapis.com/'.
178 - Block 'imp.double.net/'. Reported by David Bo in #3070411.
179 - Block 'gm-link.com/' which is used for email tracking.
180 Reported by David Bo in #1812733.
181 - Verify that requests to "bwp." are blocked. URL taken from #1736879
182 submitted by Francois Marier.
183 - Block '/.*bannerid='. Reported by Adam Piggott in #2975779.
184 - Block 'cltomedia.info/delivery/' and '.adexprt.com/'.
185 Anonymously reported in #2965254.

190 - Update path pattern for Coremetrics and add tests.
191 Pattern and URLs submitted by Adam Piggott #3168443.
192 - Enable +fast-redirects{check-decoded-url} for 'tr.anp.se/'.
193 Reported by David Bo in #3268832.

198 Reported by johnd16 in #3118401 (with a previous URL).
199 - Disable fast-redirects for Google's "let's pretend your computer is
201 - Unblock '/.*download' to resolve actionsfile feedback #3498129.
202 Submitted by Steven Kolins (soundcloud.com not working).
203 - Unblock '.wlxrs.com/' which is required by hotmail.com.
204 Fixes #3413827 submitted by David Bo.
205 - Add two unblock patterns for popup radio and TV players.
206 Submitted by Adam Piggott in #3596089.
208 - Filter file improvements & bug fixes:
209 - Add a referer tagger.
210 - Reduce the likelihood that the google filter messes up HTML-generating
211 JavaScript. Reported by Zeno Kugy in #3520260.
213 - Documentation improvements:
214 - Revised all OS X sections due to new packaging module (OSXPackageBuilder).
215 - Update the list of supported operating systems to clarify that all Windows
216 versions after 95 are expected to work and note that the platform-specific
217 code for AmigaOS and QNX currently isn't maintained.
218 - Update 'Signals' section, the only explicitly handled signals are SIGINT,
220 - Add Haiku to the list of operating systems on which Privoxy is known to
222 - Add DragonFly to the list of BSDs on which Privoxy is known to run.
223 - Removed references to redhat-specific documentation set since it no longer
225 - Removed references to building PDFs since we no longer do so.
226 - Multiple listen-address directives are supported since 3.0.18, correct the
227 documentation to say so.
228 - Remove bogus section about long and short being preferable to int.
229 - Corrected some Internet JunkBuster references to Privoxy.
230 - Removed references to www.junkbusters.com since it is no longer
231 maintained. Reported by Angelina Matson.
232 - Various grammar and spelling corrections
233 - Add a client-header-tagger{} example for disabling filtering for range
235 - Correct a URL in the "Privoxy with Tor" FAQ.
236 - Spell 'refresh-tags' correctly. Reported by Don in #3571927.
237 - Sort manpage options alphabetically.
238 - Remove an incorrect sentence in the toggle section. The toggle state
239 doesn't affect whether or not the Windows version uses the tray icon.
240 Reported by Zeno Kugy in #3596395.
241 - Add new contributors since 3.0.19.
243 - Log message improvements:
244 - When stopping to watch a client socket due to pipelining, additionally log
246 - Log the client socket and its condition before closing it. This makes it
247 more obvious that the socket actually gets closed and should help when
248 diagnosing problems like #3464439.
249 - In case of SOCKS5 failures, do not explicitly log the server's response.
250 It hasn't helped so far and the response can already be logged by enabling
251 "debug 32768" anyway. This reverts v1.81 and the follow-up bug fix v1.84.
252 - Relocate the connection-accepted message from listen_loop() to serve().
253 This way it's printed by the thread that is actually serving the
254 connection which is nice when grepping for thread ids in log files.
257 - Remove compatibility layer for versions prior to 3.0 since it has been
258 obsolete for more than 10 years now.
259 - Remove the ijb_isupper() and ijb_tolower() macros from parsers.c since
260 they aren't used in this file.
261 - Removed the 'Functions declared include:' comment sections since they tend
262 to be incomplete, incorrect and out of date and the benefit seems
264 - Various comment grammar and comprehensibility improvements.
265 - Remove a pointless fflush() call in chat(). Flushing all streams pretty
266 much all the time for no obvious reason is ridiculous.
267 - Relocate ijb_isupper()'s definition to project.h and get the ijb_tolower()
268 definition from there, too.
269 - Relocate ijb_isdigit()'s definition to project.h.
270 - Rename ijb_foo macros to privoxy_foo.
271 - Add malloc_or_die() which will allow to simplify code paths where malloc()
272 failures don't need to be handled gracefully.
273 - Add strdup_or_die() which will allow to simplify code paths where strdup()
274 failures don't need to be handled gracefully.
275 - Replace strdup() calls with strdup_or_die() calls where it's safe and
277 - Fix white-space around parentheses.
278 - Add missing white-space behind if's and the following parentheses.
279 - Unwrap a memcpy() call in resolve_hostname_to_ip().
280 - Declare pcrs_get_delimiter()'s delimiters[] static const.
281 - Various optimisations to remove dead code and merge inefficient code
282 structures for improved clarity, performance or code compactness.
283 - Various data type corrections.
284 - Change visibility of several code segments when compiling without
285 FEATURE_CONNECTION_KEEP_ALIVE enabled for clarity.
286 - In pcrs_get_delimiter(), do not use delimiters outside the ASCII range.
287 Fixes a clang complaint.
288 - Fix an error message in get_last_url() nobody is supposed to see.
289 Reported by Matthew Fischer in #3507301.
290 - Fix a typo in the no-zlib-support complaint. Patch submitted by Matthew
292 - Shorten ssplit()'s prototype by removing the last two arguments. We always
293 want to skip empty fields and ignore leading delimiters, so having
294 parameters for this only complicates the API.
295 - Use an enum for the type of the action value.
296 - Rename action_name's member takes_value to value_type as it isn't used as
298 - Turn family mismatches in match_sockaddr() into fatal errors.
299 - Let enlist_unique_header() verify that the caller didn't pass a header
300 containing either \r or \n.
301 - Change the hashes used in load_config() to unsigned int. That's what
302 hash_string() actually returns and using a potentially larger type
304 - Use privoxy_tolower() instead of vanilla tolower() with manual casting of
306 - Catch ssplit() failures in parse_cgi_parameters().
308 - Privoxy-Regression-Test:
309 - Add an 'Overwrite condition' directive to skip any matching tests before
310 it. As it has a global scope, using it is more convenient than clowning
311 around with the Ignore directive.
312 - Log to STDOUT instead of STDERR.
313 - Include the Privoxy version in the output.
314 - Various grammar and spelling corrections in documentation and code.
315 - Additional tests for range requests with filtering enabled.
316 - Tests with mostly invalid range request.
317 - Add a couple of hide-if-modified-since{} tests with different date formats.
318 - Cleaned up the format of the regression-tests.action file to match the
319 format of default.action.
320 - Remove the "Copyright" line from print_version(). When using --help, every
321 line of screen space matters and thus shouldn't be wasted on things the
322 user doesn't care about.
324 - Privoxy-Log-Parser:
325 - Improve the --statistics performance by skipping sanity checks for input
326 that shouldn't affect the results anyway. Add a --strict-checks option
327 that enables some of the checks again, just in case anybody cares.
328 - The distribution of client requests per connection is included in
329 the --statistic output.
330 - The --accept-unknown-messages option has been removed and the behavior
332 - Accept and (mostly) highlight new log messages introduced with
336 - Bump generated Firefox version to 17.
338 - GNUmakefile improvements:
339 - The dok-tidy target no longer taints documents with a tidy-mark
340 - Change RA_MODE from 0664 to 0644. Suggested by Markus Dittrich in
342 - Remove tidy's clean flag as it changes the scope of attributes.
343 Link-specific colors end up being applied to all text. Reported by Adam
345 - Leave it up to the user whether or not smart tags are inserted.
346 - Let w3m itself do the line wrapping for the config file. It works better
347 than fmt as it can honour pre tags causing less unintentional line breaks.
348 - Ditch a pointless '-r' passed to rm to delete files.
349 - The config-file target now requires less manual intervention and updates
351 - Change WDUMP to generate ASCII. Add WDUMP_UTF8 to allow UTF-8 in the
352 AUTHORS file so the names are right.
353 - Stop pretending that lynx and links are supported for the documentation.
355 - configure improvements:
356 - On Haiku, do not pass -lpthread to the compiler. Haiku's pthreads
357 implementation is contained in its system library, libroot, so no
358 additional library needs to be searched.
359 Patch submitted by Simon South in #3564815.
360 - Additional Haiku-specific improvements. Disable checks intended for
361 multi-user systems as Haiku is presently single-user. Group Haiku-specific
362 settings in their own section, following the pattern for Solaris, OS/2 and
363 AmigaOS. Add additional library-related settings to remove the need for
364 providing configure with custom LDFLAGS.
365 Submitted by Simon South in #3574538.
367 *** Version 3.0.19 Stable ***
370 - Prevent a segmentation fault when de-chunking buffered content.
371 It could be triggered by malicious web servers if Privoxy was
372 configured to filter the content and running on a platform
373 where SIZE_T_MAX isn't larger than UINT_MAX, which probably
374 includes most 32-bit systems. On those platforms, all Privoxy
375 versions before 3.0.19 appear to be affected.
376 To be on the safe side, this bug should be presumed to allow
377 code execution as proving that it doesn't seems unrealistic.
378 - Do not expect a response from the SOCKS4/4A server until it
379 got something to respond to. This regression was introduced
380 in 3.0.18 and prevented the SOCKS4/4A negotiation from working.
381 Reported by qqqqqw in #3459781.
383 - General improvements:
384 - Fix an off-by-one in an error message about connect failures.
385 - Use a GNUMakefile variable for the webserver root directory and
386 update the path. Sourceforge changed it which broke various
388 - Update the CODE_STATUS description.
390 *** Version 3.0.18 Stable ***
393 - If a generated redirect URL contains characters RFC 3986 doesn't
394 permit, they are (re)encoded. Not doing this makes Privoxy versions
395 from 3.0.5 to 3.0.17 susceptible to HTTP response splitting (CWE-113)
396 attacks if the +fast-redirects{check-decoded-url} action is used.
397 - Fix a logic bug that could cause Privoxy to reuse a server
398 socket after it got tainted by a server-header-tagger-induced
399 block that was triggered before the whole server response had
400 been read. If keep-alive was enabled and the request following
401 the blocked one was to the same host and using the same forwarding
402 settings, Privoxy would send it on the tainted server socket.
403 While the server would simply treat it as a pipelined request,
404 Privoxy would later on fail to properly parse the server's
405 response as it would try to parse the unread data from the
406 first response as server headers for the second one.
407 Regression introduced in 3.0.17.
408 - When implying keep-alive in client_connection(), remember that
409 the client didn't. Fixes a regression introduced in 3.0.13 that
410 would cause Privoxy to wait for additional client requests after
411 receiving a HTTP/1.1 request with "Connection: close" set
412 and connection sharing enabled.
413 With clients which terminates the client connection after detecting
414 that the whole body has been received it doesn't really matter,
415 but with clients that don't the connection would be kept open until
417 - Fix a subtle race condition between prepare_csp_for_next_request()
418 and sweep(). A thread preparing itself for the next client request
419 could briefly appear to be inactive.
420 If all other threads were already using more recent files,
421 the thread could get its files swept away under its feet.
422 So far this has only been reproduced while stress testing in
423 valgrind while touching action files in a loop. It's unlikely
424 to have caused any actual problems in the real world.
425 - Disable filters if SDCH compression is used unless filtering is forced.
426 If SDCH was combined with a supported compression algorithm, Privoxy
427 previously could try to decompress it and ditch the Content-Encoding
428 header even though the SDCH compression wasn't dealt with.
429 Reported by zebul666 in #3225863.
430 - Make a copy of the --user value and only mess with that when splitting
431 user and group. On some operating systems modifying the value directly
432 is reflected in the output of ps and friends and can be misleading.
433 Reported by zepard in #3292710.
434 - If forwarded-connect-retries is set, only retry if Privoxy is actually
435 forwarding the request. Previously direct connections would be retried
437 - Fixed a small memory leak when retrying connections with IPv6
439 - Remove an incorrect assertion in compile_dynamic_pcrs_job_list()
440 It could be triggered by a pcrs job with an invalid pcre
441 pattern (for example one that contains a lone quantifier).
442 - If the --user argument user[.group] contains a dot, always bail out
443 if no group has been specified. Previously the intended, but undocumented
444 (and apparently untested), behaviour was to try interpreting the whole
445 argument as user name, but the detection was flawed and checked for '0'
446 instead of '\0', thus merely preventing group names beginning with a zero.
447 - In html_code_map[], use a numeric character reference instead of '
448 which wasn't standardized before XHTML 1.0.
449 - Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION
450 and shut down through http://config.privoxy.org/die
451 - In get_actions(), fix the "temporary" backwards compatibility hack
452 to accept block actions without reason.
453 It also covered other actions that should be rejected as invalid.
454 Reported by Billy Crook.
456 - General improvements:
457 - Privoxy can (re)compress buffered content before delivering
458 it to the client. Disabled by default as most users wouldn't
460 - The +fast-redirects{check-decoded-url} action checks URL
461 segments separately. If there are other parameters behind
462 the redirect URL, this makes it unnecessary to cut them off
463 by additionally using a +redirect{} pcrs command.
464 Initial patch submitted by Jamie Zawinski in #3429848.
465 - When loading action sections, verify that the referenced filters
466 exist. Currently missing filters only result in an error message,
467 but eventually the severity will be upgraded to fatal.
468 - Allow to bind to multiple separate addresses.
469 Patch set submitted by Petr Pisar in #3354485.
470 - Set socket_error to errno if connecting fails in rfc2553_connect_to().
471 Previously rejected direct connections could be incorrectly reported
472 as DNS issues if Privoxy was compiled with IPv6 support.
473 - Adjust url_code_map[] so spaces are replaced with %20 instead of '+'
474 While '+' can be used by client's submitting form data, this is not
475 actually what Privoxy is using the lookups for. This is more of a
476 cosmetic issue and doesn't fix any known problems.
477 - When compiled without FEATURE_FAST_REDIRECTS, do not silently
478 ignore +fast-redirect{} directives
479 - Added a workaround for GNU libc's strptime() reporting negative
480 year values when the parsed year is only specified with two digits.
481 On affected systems cookies with such a date would not be turned
482 into session cookies by the +session-cookies-only action.
483 Reported by Vaeinoe in #3403560
484 - Fixed bind failures with certain GNU libc versions if no non-loopback
485 IP address has been configured on the system. This is mainly an issue
486 if the system is using DHCP and Privoxy is started before the network
487 is completely configured.
488 Reported by Raphael Marichez in #3349356.
489 Additional insight from Petr Pisar.
490 - Privoxy log messages now use the ISO 8601 date format %Y-%m-%d.
491 It's only slightly longer than the old format, but contains
492 the full date including the year and allows sorting by date
493 (when grepping in multiple log files) without hassle.
494 - In get_last_url(), do not bother trying to decode URLs that do
495 not contain at least one '%' sign. It reduces the log noise and
496 a number of unnecessary memory allocations.
497 - In case of SOCKS5 failures, dump the socks response in the log message.
498 - Simplify the signal setup in main().
499 - Streamline socks5_connect() slightly.
500 - In socks5_connect(), require a complete socks response from the server.
501 Previously Privoxy didn't care how much data the server response
502 contained as long as the first two bytes contained the expected
503 values. While at it, shrink the buffer size so Privoxy can't read
504 more than a whole socks response.
505 - In chat(), do not bother to generate a client request in case of
506 direct CONNECT requests. It will not be used anyway.
507 - Reduce server_last_modified()'s stack size.
508 - Shorten get_http_time() by using strftime().
509 - Constify the known_http_methods pointers in unknown_method().
510 - Constify the time_formats pointers in parse_header_time().
511 - Constify the formerly_valid_actions pointers in action_used_to_be_valid().
512 - Introduce a GNUMakefile MAN_PAGE variable that defaults to privoxy.1.
513 The Debian package uses section 8 for the man page and this
514 should simplify the patch.
515 - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
516 - In block_url(), ditch the obsolete workaround for ancient Netscape versions
517 that supposedly couldn't properly deal with status code 403.
518 - Remove a useless NULL pointer check in load_trustfile().
519 - Remove two useless NULL pointer checks in load_one_re_filterfile().
520 - Change url_code_map[] from an array of pointers to an array of arrays
521 It removes an unnecessary layer of indirection and on 64bit system reduces
522 the size of the binary a bit.
523 - Fix various typos. Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
524 - Add a dok-tidy GNUMakefile target to clean up the messy HTML
525 generated by the other dok targets.
526 - GNUisms in the GNUMakefile have been removed.
527 - Change the HTTP version in static responses to 1.1
528 - Synced config.sub and config.guess with upstream
529 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
530 - Add a dedicated function to parse the values of toggles. Reduces duplicated
531 code in load_config() and provides better error handling. Invalid or missing
532 toggle values are now a fatal error instead of being silently ignored.
533 - Terminate HTML lines in static error messages with \n instead of \r\n.
534 - Simplify cgi_error_unknown() a bit.
535 - In LogPutString(), don't bother looking at pszText when not
536 actually logging anything.
537 - Change ssplit()'s fourth parameter from int to size_t.
538 Fixes a clang complaint.
539 - Add a warning that the statistics currently can't be trusted.
540 Mention Privoxy-Log-Parser's --statistics option as
541 an alternative for the time being.
542 - In rfc2553_connect_to(), start setting cgi->error_message on error.
543 - Change the expected status code returned for http://p.p/die depending
544 on whether or not FEATURE_GRACEFUL_TERMINATION is available.
545 - In cgi_die(), mark the client connection for closing.
546 If the client will fetch the style sheet through another connection
547 it gets the main thread out of the accept() state and should thus
548 trigger the actual shutdown.
549 - Add a proper CGI message for cgi_die().
550 - Don't enforce a logical line length limit in read_config_line().
551 - Slightly refactor server_last_modified() to remove useless gmtime*() calls.
552 - In get_content_type(), also recognize '.jpeg' as JPEG extension.
553 - Add '.png' to the list of recognized file extensions in get_content_type().
554 - In block_url(), consistently use the block reason "Request blocked by Privoxy"
555 In two places the reason was "Request for blocked URL" which hides the
556 fact that the request got blocked by Privoxy and isn't necessarily
557 correct as the block may be due to tags.
558 - In listen_loop(), reload the configuration files after accepting
559 a new connection instead of before.
560 Previously the first connection that arrived after a configuration
561 change would still be handled with the old configuration.
562 - In chat()'s receive-data loop, skip a client socket check if
563 the socket will be written to right away anyway. This can
564 increase the transfer speed for unfiltered content on fast
566 - The socket timeout is used for SOCKS negotiations as well which
567 previously couldn't timeout.
568 - Don't keep the client connection alive if any configuration file
569 changed since the time the connection came in. This is closer to
570 Privoxy's behaviour before keep-alive support for client connection
571 has been added and also less confusing in general.
572 - Treat all Content-Type header values containing the pattern
573 'script' as a sign of text. Reported by pribog in #3134970.
575 - Action file improvements:
576 - Moved the site-specific block pattern section below the one for the
577 generic patterns so for requests that are matched in both, the block
578 reason for the domain is shown which is usually more useful than showing
579 the one for the generic pattern.
580 - Remove -prevent-compression from the fragile alias. It's no longer
581 used anywhere by default and isn't known to break stuff anyway.
582 - Add a (disabled) section to block various Facebook tracking URLs.
583 Reported by Dan Stahlke in #3421764.
584 - Add a (disabled) section to rewrite and redirect click-tracking
585 URLs used on news.google.com.
586 Reported by Dan Stahlke in #3421755.
587 - Unblock linuxcounter.net/.
588 Reported by Dan Stahlke in #3422612.
589 - Block 'www91.intel.com/' which is used by Omniture.
590 Reported by Adam Piggott in #3167370.
591 - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
592 Reminded by tceverling in #2790091.
593 - Add ".ivwbox.de/" to the "Cross-site user tracking" section.
594 Reported by Nettozahler in #3172525.
595 - Unblock and fast-redirect ".awin1.com/.*=http://".
596 Reported by Adam Piggott in #3170921.
597 - Block "b.collective-media.net/".
598 - Widen the Debian popcon exception to "qa.debian.org/popcon".
599 Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
600 - Block ".gemius.pl/" which only seems to be used for user tracking.
601 Reported by johnd16 in #3002731. Additional input from Lee and movax.
602 - Disable banners-by-size filters for '.thinkgeek.com/'.
603 The filter only seems to catch pictures of the inventory.
604 - Block requests for 'go.idmnet.bbelements.com/please/showit/'.
605 Reported by kacperdominik in #3372959.
606 - Unblock adainitiative.org/.
607 - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'.
608 - Add a fast-redirects exception for webcache.googleusercontent.com/.
609 - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/.
611 - Filter file improvements:
612 - Let the yahoo filter hide '.ads'.
613 - Let the msn filter hide overlay ads for Facebook 'likes' in search
614 results and elements with the id 's_notf_div'. They only seem to be
615 used to advertise site 'enhancements'.
616 - Let the js-events filter additionally disarm setInterval().
617 Suggested by dg1727 in #3423775.
619 - Documentation improvements:
620 - Clarify the effect of compiling Privoxy with zlib support.
621 Suggested by dg1727 in #3423782.
622 - Point out that the SourceForge messaging system works like a black
623 hole and should thus not be used to contact individual developers.
624 - Mention some of the problems one can experience when not explicitly
625 configuring an IP addresses as listen address.
626 - Explicitly mention that hostnames can be used instead of IP addresses
627 for the listen-address, that only the first address returned will be
628 used and what happens if the address is invalid.
629 Requested by Calestyo in #3302213.
631 - Log message improvements:
632 - If only the server connection is kept alive, do not pretend to
633 wait for a new client request.
634 - Remove a superfluous log message in forget_connection().
635 - In chat(), properly report missing server responses as such
636 instead of calling them empty.
637 - In forwarded_connect(), fix a log message nobody should ever see.
638 - Fix a log message in socks5_connect(), a failed write operation
639 was logged as failed read operation.
640 - Let load_one_actions_file() properly complain about a missing
641 '{' at the beginning of the file.
642 Simply stating that a line is invalid isn't particularly helpful.
643 - Do not claim to listen on a socket until Privoxy actually does.
644 Patch submitted by Petr Pisar #3354485
645 - Prevent a duplicated LOG_LEVEL_CLF message when sending out
646 the "no-server-data" response.
647 - Also log the client socket when dropping a connection.
648 - Include the destination host in the 'Request ... marked for
649 blocking. limit-connect{...} doesn't allow CONNECT ...' message
650 Patch submitted by Saperski in #3296250.
651 - Prevent a duplicated log message if none of the resolved IP
652 addresses were reachable.
653 - In connect_to(), do not pretend to retry if forwarded-connect-retries
655 - When a specified user or group can't be found, put the name in
656 single-quotes when logging it.
657 - In rfc2553_connect_to(), explain getnameinfo() errors better.
658 - Remove a useless log message in chat().
659 - When retrying to connect, also log the maximum number of connection
661 - Rephrase a log message in compile_dynamic_pcrs_job_list().
662 Divide the error code and its meaning with a colon. Call the pcrs
663 job dynamic and not the filter. Filters may contain dynamic and
664 non-dynamic pcrs jobs at the same time. Only mention the name of
665 the filter or tagger, but don't claim it's a filter when it could
667 - In a fatal error message in load_one_actions_file(), cover both
668 URL and TAG patterns.
669 - In pcrs_strerror(), properly report unknown positive error code
670 values as such. Previously they were handled like 0 (no error).
671 - In compile_dynamic_pcrs_job_list(), also log the actual error code as
672 pcrs_strerror() doesn't handle all errors reported by pcre.
673 - Don't bother trying to continue chatting if the client didn't ask for it.
674 Reduces log noise a bit.
675 - Make two fatal error message in load_one_actions_file() more descriptive.
676 - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'.
677 - In load_file(), log a message if opening a file failed.
678 The CGI error message alone isn't too helpful.
679 - In connection_destination_matches(), improve two log messages
680 to help understand why the destinations don't match.
681 - Rephrase a log message in serve(). Client request arrival
682 should be differentiated from closed client connections now.
683 - In serve(), log if a client connection isn't reused due to a
684 configuration file change.
685 - Let mark_server_socket_tainted() always mark the server socket tainted,
686 just don't talk about it in cases where it has no effect. It doesn't change
687 Privoxy's behaviour, but makes understanding the log file easier.
690 - Added a --disable-ipv6-support switch for platforms where support
691 is detected but doesn't actually work.
692 - Do not check for the existence of strerror() and memmove() twice
693 - Remove a useless test for setpgrp(2). Privoxy doesn't need it and
694 it can cause problems when cross-compiling.
695 - Rename the --disable-acl-files switch to --disable-acl-support.
696 Since about 2001, ACL directives are specified in the standard
698 - Update the URL of the 'Removing outdated PCRE version after the
699 next stable release' posting. The old URL stopped working after
700 one of SF's recent site "optimizations". Reported by Han Liu.
702 - Privoxy-Regression-Test:
703 - Added --shuffle-tests option to increase the chances of detection race conditions.
704 - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy.
705 - Added tests for missing socks4 and socks4a forwarders.
706 - The --privoxy-address option now works with IPv6 addresses containing brackets, too.
707 - Perform limited sanity checks for parameters that are supposed to have numerical values.
708 - Added a --sleep-time option to specify a number of seconds to
709 sleep between tests, defaults to 0.
710 - Disable the range-requests tagger for tests that break if it's enabled.
711 - Log messages use the ISO 8601 date format %Y-%m-%d.
712 - Fix spelling in two error messages.
713 - In the --help output, include a list of supported tests and their default levels.
714 - Adjust the tests to properly deal with FEATURE_TOGGLE being disabled.
716 - Privoxy-Log-Parser:
717 - Perform limited sanity checks for command line parameters that
718 are supposed to have numerical values.
719 - Implement a --unbreak-lines-only option to try to revert MUA breakage.
720 - Accept and highlight: Added header: Content-Encoding: deflate
721 - Accept and highlight: Compressed content from 29258 to 8630 bytes.
722 - Accept and highlight: Client request arrived in time on socket 21.
723 - Highlight: Didn't receive data in time: a.fsdn.com:443
724 - Accept log messages with ISO 8601 time stamps, too.
727 - Bump generated Firefox version to 8.0.
728 - Only randomize the release date if the new --randomize-release-date
729 option is enabled. Firefox versions after 4 use a fixed date string
732 *** Version 3.0.17 Stable ***
734 - Fixed last-chunk-detection for responses where the body was small
735 enough to be read with the headers, causing Privoxy to wait for the
736 end of the content until the server closed the connection or the
737 request timed out. Reported by "Karsten" in #3028326.
738 - Responses with status code 204 weren't properly detected as body-less
739 like RFC2616 mandates. Like the previous bug, this caused Privoxy to
740 wait for the end of the content until the server closed the connection
741 or the request timed out. Fixes #3022042 and #3025553, reported by a
742 user with no visible name. Most likely also fixes a bunch of other
743 AJAX-related problem reports that got closed in the past due to
744 insufficient information and lack of feedback.
745 - Fixed an ACL bug that made it impossible to build a blacklist.
746 Usually the ACL directives are used in a whitelist, which worked
747 as expected, but blacklisting is still useful for public proxies
748 where one only needs to deny known abusers access.
749 - Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
750 network. This should make debugging various parsing issues a lot easier.
751 - The IPv6 code is enabled by default on Windows versions that support it.
752 Patch submitted by oCameLo in #2942729.
753 - In mingw32 versions, the user.filter file is reachable through the
754 GUI, just like default.filter is. Feature request 3040263.
755 - Added the configure option --enable-large-file-support to set a few
756 defines that are required by platforms like GNU/Linux to support files
757 larger then 2GB. Mainly interesting for users without proper logfile
759 - Logging with "debug 16" no longer stops at the first nul byte which is
760 pretty useless. Non-printable characters are replaced with their hex value
761 so the result can't span multiple lines making parsing them harder then
763 - Privoxy logs when reading an action, filter or trust file.
764 - Fixed incorrect regression test markup which caused a test in
765 3.0.16 to fail while Privoxy itself was working correctly.
766 While Privoxy accepts hide-referer, too, the action name is actually
767 hide-referrer which is also the name used one the final results page,
768 where the test expected the alias.
770 - CGI interface improvements:
771 - In finish_http_response(), continue to add the 'Connection: close'
772 header if the client connection will not be kept alive.
773 Anonymously pointed out in #2987454.
774 - Apostrophes in block messages no longer cause parse errors
775 when the blocked page is viewed with JavaScript enabled.
776 Reported by dg1727 in #3062296.
777 - Fix a bunch of anchors that used underscores instead of dashes.
778 - Allow to keep the client connection alive after crunching the previous request.
779 Already opened server connections can be kept alive, too.
780 - In cgi_show_url_info(), don't forget to prefix URLs that only contain
781 http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott.
782 - Show the 404 CGI page if cgi_send_user_manual() is called while
783 local user manual delivery is disabled.
785 - Action file improvements:
786 - Enable user.filter by default. Suggested by David White in #3001830.
787 - Block .sitestat.com/. Reported by johnd16 in #3002725.
788 - Block .atemda.com/. Reported by johnd16 in #3002723.
789 - Block js.adlink.net/. Reported by johnd16 in #3002720.
790 - Block .analytics.yahoo.com/. Reported by johnd16 in #3002713.
791 - Block sb.scorecardresearch.com, too. Reported by dg1727 in #2992652.
792 - Fix problems noticed on Yahoo mail and news pages.
793 - Remove the too broad yahoo section, only keeping the
794 fast-redirects exception as discussed on ijbswa-devel@.
795 - Don't block adesklets.sourceforge.net. Reported in #2974204.
796 - Block chartbeat ping tracking. Reported in #2975895.
797 - Tag CSS and image requests with cautious and medium settings, too.
798 - Don't handle view.atdmt.com as image. It's used for click-throughs
799 so users should be able to "go there anyway".
800 Reported by Adam Piggott in #2975927.
801 - Also let the refresh-tags filter remove invalid refresh tags where
802 the 'url=' part is missing. Anonymously reported in #2986382.
803 While at it, update the description to mention the fact that only
804 refresh tags with refresh times above 9 seconds are covered.
805 - javascript needs to be blocked with +handle-as-empty-document to
806 work around Firefox bug 492459. So move .js blockers from
807 +block{Might be a web-bug.} -handle-as-empty-document to
808 +block{Might be a web-bug.} +handle-as-empty-document.
809 - ijbswa-Feature Requests-3006719 - Block 160x578 Banners.
810 - Block another omniture tracking domain.
811 - Added a range-requests tagger.
812 - Added two sections to get Flickr's Ajax interface working with
813 default pre-settings. If you change the configuration to block
814 cookies by default, you'll need additional exceptions.
815 Reported by Mathias Homann in #3101419 and by Patrick on ijbswa-users@.
817 - Documentation improvements:
818 - Explicitly mention how to match all URLs.
819 - Consistently recommend socks5 in the Tor FAQ entry and mention
820 its advantage compared to socks4a. Reported by David in #2960129.
821 - Slightly improve the explanation of why filtering may appear
823 - Grammar fixes for the ACL section.
824 - Fixed a link to the 'intercepting' entry and add another one.
825 - Rename the 'Other' section to 'Mailing Lists' and reword it
826 to make it clear that nobody is forced to use the trackers
827 - Note that 'anonymously' posting on the trackers may not always
829 - Suggest to enable debug 32768 when suspecting parsing problems.
831 - Privoxy-Log-Parser improvements:
832 - Gather statistics for ressources, methods, and HTTP versions
834 - Also gather statistics for blocked and redirected requests.
835 - Provide the percentage of keep-alive offers the client accepted.
836 - Add a --url-statistics-threshold option.
837 - Add a --host-statistics-threshold option to also gather
838 statistics about how many request where made per host.
839 - Fix a bug in handle_loglevel_header() where a 'scan: ' got lost.
840 - Add a --shorten-thread-ids option to replace the thread id with
842 - Accept and ignore: Looks like we got the last chunk together
843 with the server headers. We better stop reading.
844 - Accept and ignore: Continue hack in da house.
845 - Accept and higlight: Rejecting connection from 10.0.0.2.
846 Maximum number of connections reached.
847 - Accept and highlight: Loading actions file: /usr/local/etc/privoxy/default.action
848 - Accept and highlight: Loading filter file: /usr/local/etc/privoxy/default.filter
849 - Accept and highlight: Killed all-caps Host header line: HOST: bestproxydb.com
850 - Accept and highlight: Reducing expected bytes to 0. Marking
851 the server socket tainted after throwing 4 bytes away.
852 - Accept: Merged multiple header lines to: 'X-FORWARDED-PROTO: http X-HOST: 127.0.0.1'
855 - Remove the next member from the client_state struct. Only the main
856 thread needs access to all client states so give it its own struct.
857 - Garbage-collect request_contains_null_bytes().
858 - Ditch redundant code in unload_configfile().
859 - Ditch LogGetURLUnderCursor() which doesn't seem to be used anywhere.
860 - In write_socket(), remove the write-only variable write_len in
861 an ifdef __OS2__ block. Spotted by cppcheck.
862 - In connect_to(), don't declare the variable 'flags' on OS/2 where
863 it isn't used. Spotted by cppcheck.
864 - Limit the scope of various variables. Spotted by cppcheck.
865 - In add_to_iob(), turn an interestingly looking for loop into a
867 - Code cleanup in preparation for external filters.
868 - In listen_loop(), mention the socket on which we accepted the
869 connection, not just the source IP address.
870 - In write_socket(), also log the socket we're writing to.
871 - In log_error(), assert that escaped characters get logged
872 completely or not at all.
873 - In log_error(), assert that ival and sval have reasonable values.
874 There's no reason not to abort() if they don't.
875 - Remove an incorrect cgi_error_unknown() call in a
876 cannot-happen-situation in send_crunch_response().
877 - Clean up white-space in http_response definition and
878 move the crunch_reason to the beginning.
879 - Turn http_response.reason into an enum and rename it
880 to http_response.crunch_reason.
881 - Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686 GNU/Linux.
882 - Fix white-space in a log message in remove_chunked_transfer_coding().
883 While at it, add a note that the message doesn't seem to
884 be entirely correct and should be improved later on.
886 - GNUmakefile improvements:
887 - Use $(SSH) instead of ssh, so one only needs to specify a username once.
888 - Removed references to the action feedback thingy that hasn't been
890 - Consistently use shell.sourceforge.net instead of shell.sf.net so
891 one doesn't need to check server fingerprints twice.
892 - Removed GNUisms in the webserver and webactions targets so they
893 work with standard tar.
895 *** Version 3.0.16 Stable ***
897 - Added the config file option handle-as-empty-doc-returns-ok to
898 work around Firefox bug #492459, which causes Firefox to hang
899 if JavaScripts are blocked in certain situations. The option is
900 enabled in the default config file.
901 - Added the config file option default-server-timeout to control the
902 assumed default server timeout. Since Privoxy no longer returns
903 an error message for connection resets on reused client connections,
904 assuming larger server timeout values appears to actually work
905 pretty well as long as connections aren't shared.
906 - Added optional support for FreeBSD's accf_http(9). Use the
907 configure option --enable-accept-filter to enable it.
908 - Added fancier Privoxy icons for win32. Contributed by Jeff H.
909 - In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
910 - Resolve localhost using whatever address family the operating
911 system feels like. Previous betas would try to use IPv4 as this
912 is what most users expect, but this didn't work reliably on
914 - In the action lists on CGI pages, actions and their parameters are
915 no longer separated with a space. The action file parser doesn't
916 actually allow this and will throw an invalid syntax error if actions
917 and parameters in the action files are separated. Not adding the
918 spaces means copy and pasting CGI output into the action files works.
919 - The default keep-alive timeout has been reduced to 5 seconds to work
920 around hangs in clients that treat the proxy like any other host and
921 stop allowing any new connections if the "maximum number of
922 connections per host" is reached.
923 - Several webbug URLs that look like they are leading to images are now
924 blocked as image instead of empty documents. Doing the latter causes
925 WebKit-based clients to show a "missing image" icon which may mess up
927 - The no-such-domain template is used for DNS resolution
928 problems with FEATURE_IPV6_SUPPORT enabled. Previously the
929 connect-failed template was used. Reported by 'zebul666'.
930 - Accepts quoted expiration dates even though RFC 2109 10.1.2
931 doesn't seem to allow them. Reported anonymously.
932 - Don't try to forget connections if connection sharing is disabled.
933 This wasn't a real problem but caused an unnecessary log message.
934 - The still undocumented --enable-extended-host-patterns configure
935 option has a better description.
936 - Fixed an error message that would claim a write to the server
937 failed when actually writing to the client failed.
938 - Log the crunch reason before trying to write to the client.
939 The log is easier to read that way.
940 - Several log messages about client connections also mention
942 - handle-as-empty-document no longer depends on the image blocking
944 - Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
945 - uagen, a Firefox User-Agent generator for Privoxy and Mozilla
946 browsers has been imported and is available in the tarball's
948 - The scripts in the tools directory treat unknown parameters
951 *** Version 3.0.15 beta ***
953 - In case of missing server data, no error message is send to the
954 client if the request arrived on a reused connection. The client
955 is then supposed to silently retry the request without bothering
956 the user. This should significantly reduce the frequency of the
957 "No server or forwarder data received" error message many users
959 - More reliable detection of prematurely closed client sockets
960 with keep-alive enabled.
961 - FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
962 FEATURE_CONNECTION_SHARING and now available on
964 - Improved handling of POST requests on reused connections.
965 Should fix problems with stalled connections after submitting
966 form data with some browser configurations.
967 - Fixed various latency calculation issues.
968 - Allows the client to pass NTLM authentication requests to a
969 forwarding proxy. This was already assumed and hinted to work
970 in 3.0.13 beta but actually didn't. Now it's confirmed to work
971 with IE, Firefox and Chrome.
972 Thanks to Francois Botha and Wan-Teh Chang
973 - Fixed a calculation problem if receiving the server headers
974 takes more than two reads, that could cause Privoxy to terminate
975 the connection prematurely. Reported by Oliver.
976 - Compiles again on platforms such as OpenBSD and systems
977 using earlier glibc version that don't support AI_ADDRCONFIG.
978 Anonymously submitted in #2872591.
979 - A bunch of MS VC project files and Suse and Redhat RPM spec
980 files have been removed as they were no longer maintained for
982 - Overly long action lines are properly rejected with a proper
983 error message. Previously they would be either rejected as
984 invalid or cause a core dump through abort().
985 - Already timed-out connections are no longer temporarily remembered.
986 They weren't reused anyway, but wasted a socket slot.
987 - len refers to the number of bytes actually read which might
988 differ from the ones received. Adjust log messages accordingly.
989 - The optional JavaScript on the CGI page uses encodeURIComponent()
990 instead of escape() which doesn't encode all characters that matter.
991 Anonymously reported in #2832722.
992 - Fix gcc45 warnings in decompress_iob().
993 - Various log message improvements.
994 - Privoxy-Regression-Test supports redirect tests.
995 - Privoxy-Log-Parser can gather some connection statistics.
997 *** Version 3.0.14 beta ***
999 - The latency is taken into account when evaluating whether or not to
1000 reuse a connection. This should significantly reduce the number of
1001 connections problems several users reported.
1002 - If the server doesn't specify how long the connection stays alive,
1003 Privoxy errs on the safe side of caution and assumes it's only a second.
1004 - The error pages for connection timeouts or missing server data use a
1005 Last-Modified date in the past. Retry attempts are detected and Privoxy
1006 removes the If-Modified-Since header to prevent the server from responding
1007 with status code 304 in which case the client would reuse the error message.
1008 - Setting keep-alive-timeout to 0 disables keep-alive support. Previously
1009 Privoxy would claim to allow persistence but not reuse the connection.
1010 - Pipelined requests are less likely to be mistaken for the request
1011 body of the previous request. Note that Privoxy still has no real
1012 pipeline support and will either serialize pipelined requests or
1013 drop them in which case the client has to resent them.
1014 - Fixed a crash on some Windows versions when header randomization
1015 is enabled and the date couldn't be parsed.
1016 - Privoxy's keep-alive timeout for the current connection is reduced
1017 to the one specified in the client's Keep-Alive header.
1018 - For HTTP/1.1 requests, Privoxy implies keep-alive support by not
1019 setting any Connection header instead of using 'Connection: keep-alive'.
1020 - If the socket isn't reusable, Privoxy doesn't temporarily waste
1021 a socket slot to remember the connection.
1022 - If keep-alive support is disabled but compiled in, the client's
1023 Keep-Alive header is removed.
1024 - Fixed a bug on mingw32 where downloading large files failed if
1025 keep-alive support was enabled.
1026 - Fixed a bug that (at least theoretically) could cause log
1027 timestamps to be occasionally off by about a second.
1028 - No Proxy-Connection header if added if there already is one.
1029 - The configure script respects the $PATH variable when searching
1032 *** Version 3.0.13 beta ***
1034 - Added IPv6 support. Thanks to Petr Pisar who not only provided
1035 the initial patch but also helped a lot with the integration.
1036 - Added client-side keep-alive support.
1037 - The connection sharing code is only used if the connection-sharing
1039 - The max-client-connections option has been added to restrict
1040 the number of client connections below a value enforced by
1041 the operating system.
1042 - Fixed a regression reintroduced in 3.0.12 that could cause
1043 crashes on mingw32 if header date randomization was enabled.
1044 - Compressed content with extra fields couldn't be decompressed
1045 and would get passed to the client unfiltered. This problem
1046 has only be detected through statical analysis with clang as
1047 nobody seems to be using extra fields anyway.
1048 - If the server resets the Connection after sending only the headers
1049 Privoxy forwards what it got to the client. Previously Privoxy
1050 would deliver an error message instead.
1051 - Error messages in case of connection timeouts use the right
1053 - If spawning a child to handle a request fails, the client
1054 gets an error message and Privoxy continues to listen for
1055 new requests right away.
1056 - The error messages in case of server-connection timeouts or
1057 prematurely closed server connections are now template-based.
1058 - If zlib support isn't compiled in, Privoxy no longer tries to
1059 filter compressed content unless explicitly asked to do so.
1060 - In case of connections that are denied based on ACL directives,
1061 the memory used for the client IP is no longer leaked.
1062 - Fixed another small memory leak if the client request times out
1063 while waiting for client headers other than the request line.
1064 - The client socket is kept open until the server socket has
1065 been marked as unused. This should increase the chances that
1066 the still-open connection will be reused for the client's next
1067 request to the same destination. Note that this only matters
1068 if connection-sharing is enabled.
1069 - A TODO list has been added to the source tarball to give potential
1070 volunteers a better idea of what the current goals are. Donations
1071 are still welcome too: http://www.privoxy.org/faq/general.html#DONATE
1073 *** Version 3.0.12 ***
1075 - The socket-timeout option now also works on platforms whose
1076 select() implementation modifies the timeout structure.
1077 Previously the timeout was triggered even if the connection
1078 didn't stall. Reported by cyberpatrol.
1079 - The Connection: keep-alive code properly deals with files
1080 larger than 2GB. Previously the connection was closed too
1082 - The content length for files above 2GB is logged correctly.
1083 - The user-manual directive on the show-status page links to
1084 the documentation location specified with the directive,
1085 not to the Privoxy website.
1086 - When running in daemon mode, Privoxy doesn't log anything
1087 to the console unless there are errors before the logfile
1089 - The show-status page prints warnings about invalid directives
1090 on the same line as the directives themselves.
1091 - Fixed several justified (but harmless) compiler warnings,
1092 mostly on 64 bit platforms.
1093 - The mingw32 version explicitly requests the default charset
1094 to prevent display problems with some fonts available on more
1095 recent Windows versions. Patch by Burberry.
1096 - The mingw32 version uses the Privoxy icon in the alt-tab
1097 windows. Patch by Burberry.
1098 - The timestamp and the thread id is omitted in the "Fatal error"
1099 message box on mingw32.
1100 - Fixed two related mingw32-only buffer overflows. Triggering
1101 them required control over the configuration file, therefore
1102 this isn't seen as a security issue.
1103 - In verbose mode, or if the new option --show-skipped-tests
1104 is used, Privoxy-Regression-Test logs skipped tests and the
1107 *** Version 3.0.11 ***
1109 - On most platforms, outgoing connections can be kept alive and
1110 reused if the server supports it. Whether or not this improves
1111 things depends on the connection.
1112 - When dropping privileges, membership in supplementary groups
1113 is given up as well. Not doing that can lead to Privoxy running
1114 with more rights than necessary and violates the principle of
1115 least privilege. Users of the --user option are advised to update.
1116 Thanks to Matthias Drochner for reporting the problem,
1117 providing the initial patch and testing the final version.
1118 - Passing invalid users or groups with the --user option
1119 didn't lead to program exit. Regression introduced in 3.0.7.
1120 - The match all section has been moved from default.action
1121 to a new file called match-all.action. As a result the
1122 default.action no longer needs to be touched by the user
1123 and can be safely overwritten by updates.
1124 - The standard.action file has been removed. Its content
1125 is now part of the default.action file.
1126 - In some situations the logged content length was slightly too low.
1127 - Crunched requests are logged with their own log level.
1128 If you used "debug 1" in the past, you'll probably want
1129 to additionally enable "debug 1024", otherwise only passed
1130 requests will be logged. If you only care about crunched
1131 requests, simply replace "debug 1" with "debug 1024".
1132 - The crunch reason has been moved to the beginning of the
1133 crunch message. For HTTP URLs, the protocol is logged as well.
1134 - Log messages are shortened by printing the thread id on its
1135 own (as opposed to putting it inside the string "Privoxy()").
1136 - The config option socket-timeout has been added to control
1137 the time Privoxy waits for data to arrive on a socket.
1138 - Support for remote toggling is controlled by the configure
1139 option --disable-toggle only. In previous versions it also
1140 depended on the action editor and thus configuring with the
1141 --disable-editor option would disable remote toggling support
1143 - Requests with invalid HTTP versions are rejected.
1144 - The template symbol @date@ can be used to include a date(1)-like
1145 time string. Initial patch submitted by Endre Szabo.
1146 - Responses from shoutcast servers are accepted again.
1147 Problem reported and fix suggested by Stefan.
1148 - The hide-forwarded-for-headers action has been replaced with
1149 the change-x-forwarded-for{} action which can also be used to
1150 add X-Forwarded-For headers. The latter functionality already
1151 existed in Privoxy versions prior to 3.0.7 but has been removed
1152 as it was often used unintentionally (by not using the
1153 hide-forwarded-for-headers action).
1154 - A "clear log" view option was added to the mingw32 version
1155 to clear out all of the lines in the Privoxy log window.
1156 Based on a patch submitted by T Ford.
1157 - The mingw32 version uses "critical sections" now, which prevents
1158 log message corruption under load. As a side effect, the
1159 "no thread-safe PRNG" warning could be removed as well.
1160 - The mingw32 version's task bar icon is crossed out and
1161 the color changed to gray if Privoxy is toggled off.
1163 *** Version 3.0.10 ***
1165 - Ordinary configuration file changes no longer cause program
1166 termination on OS/2 if the name of the logfile hasn't been
1167 changed as well. This regression probably crept in with the
1168 logging improvements in 3.0.7. Reported by Maynard.
1169 - The img-reorder filter is less likely to mess up JavaScript code in
1170 img tags. Problem and solution reported by Glenn Washburn in #2014552.
1171 - The source tar ball now includes Privoxy-Log-Parser,
1172 a syntax-highlighter for Privoxy logs. For fancy screenshots see:
1173 http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
1174 Documentation is available through perldoc(1).
1176 *** Version 3.0.9 beta ***
1178 - Added SOCKS5 support (with address resolution done by
1179 the SOCKS5 server). Patch provided by Eric M. Hopper.
1180 - The "blocked" CGI pages include a block reason that was
1181 provided as argument to the last-applying block action.
1182 - If enable-edit-actions is disabled (the default since 3.0.7 beta)
1183 the show-status page hides the edit buttons and explains why.
1184 Previously the user would get the "this feature has been disabled"
1185 message after using the edit button.
1186 - Forbidden CONNECT requests are treated like blocks by default.
1187 The now-pointless treat-forbidden-connects-like-blocks action
1189 - Not enabling limit-connect now allows CONNECT requests to all ports.
1190 In previous versions it would only allow CONNECT requests to port 443.
1191 Use +limit-connect{443} if you think you need the old default behaviour.
1192 - The CGI editor gets turned off after three edit requests with invalid
1193 file modification timestamps. This makes life harder for attackers
1194 who can leverage browser bugs to send fake Referers and intend to
1195 brute-force edit URLs.
1196 - Action settings for multiple patterns in the same section are
1197 shared in memory. As a result these sections take up less space
1198 (and are loaded slightly faster). Problem reported by Franz Schwartau.
1199 - Linear white space in HTTP headers will be normalized to single
1200 spaces before parsing the header's content, headers split across
1201 multiple lines get merged first. This should prevent problems like:
1202 * letting the session-cookies-only action slip
1203 some Cookies through unmodified,
1204 * only suppressing the first line of a header,
1205 thus creating an invalid one, and
1206 * to incorrectly block headers with valid timestamps
1207 that weren't properly recognized.
1208 Headers that could trigger these problems are unlikely to appear
1209 in "normal" web traffic, but could be intentionally generated to
1210 fool some of Privoxy's header parsers.
1211 - Host information is gathered outside the main thread so it's less
1212 likely to delay other incoming connections if the host is misconfigured.
1213 - New config option "hostname" to use a hostname other than
1214 the one returned by the operating system. Useful to speed-up responses
1215 for CGI requests on misconfigured systems. Requested by Max Khon.
1216 - The CGI editor supports the "disable all filters of this type"
1217 directives "-client-header-filter", "-server-header-filter",
1218 "-client-header-tagger" and "-server-header-tagger".
1219 - Fixed false-positives with the link-by-url filter and URLs that
1220 contain the pattern "/jump/".
1221 - The less-download-windows filter no longer messes
1222 "Content-Type: application/x-shockwave-flash" headers up.
1223 - In the show-url-info page's "Final results" section active and
1224 inactive actions are listed separately. Patch provided by Lee.
1225 - The GNUmakefile supports the DESTDIR variable. Patch for
1226 the install target submitted by Radoslaw Zielinski.
1227 - Embedding the content of configuration files in the show-status
1228 page is significantly faster now. For a largish action file (1 MB)
1229 a speedup of about 2450 times has been measured. This is mostly
1230 interesting if you are using large action files or regularly use
1231 Privoxy-Regression-Test while running Privoxy through Valgrind,
1232 for stock configuration files it doesn't really matter.
1233 - If zlib support is unavailable and there are content
1234 filters active but the prevent-compression action is disabled,
1235 the show-url-info page includes a warning that compression
1236 might prevent filtering.
1237 - The show-url-info page provides an OpenSearch Description that
1238 allows to access the page through browser search plugins.
1239 - Custom client-header filters that rewrite the request line
1240 incorrectly no longer cause Privoxy to crash. Reported by din_a4.
1241 - The obsolete kill-popups action has been removed as the
1242 PCRS-based popup filters can do the same and are slightly
1244 - The inspect-jpegs action has been removed.
1245 - The send-wafer and send-vanilla-wafer actions have been removed.
1246 They weren't particular useful and their behaviour could be emulated
1247 with add-header anyway.
1248 - Privoxy-Regression-Test has been significantly improved.
1249 - Most sections in the default.action file contain tests for
1250 Privoxy-Regression-Test to verify that they are working as intended.
1251 - Parts of Privoxy have been refactored to increase maintainability.
1252 - Building with zlib (if available) is done by default.
1254 *** Version 3.0.8 ***
1256 - Fixed a small memory leak when listen-address only specifies the port.
1257 - The source tar balls now include Privoxy-Regression-Test which
1258 (upon other things) can be used to automatically detect some
1259 packaging problems. Packagers are welcome to give it a try.
1260 - Reverted a change in 3.0.7 that caused path patterns to be checked
1261 even if the host pattern match already failed. While this doesn't
1262 noticeable affect the performance, it makes it less likely to run
1263 out of stack space with overly-complex path patterns the user might
1265 - Updated the msn, yahoo and google filters to work as advertised again.
1266 - The warning message shown by the show-status CGI page is easier to
1267 understand. Previously it wasn't clear that the error message
1268 is shown below the invalid directive. (Reported by Lee)
1269 - When regenerating Content-Disposition headers the more common
1270 spelling is used for the name. Previously it was written without caps.
1271 - Less confusing log message if the content type isn't overwritten
1272 because force-text-type wasn't used but the old type doesn't look
1273 like content that would be filtered normally.
1274 - Better log messages if the user tries to execute filters that
1276 - Treat the non-standard Request-Range headers like standard range
1277 headers and suppress them if content filtering is enabled.
1278 - Prevent the log messages for CONNECT requests to unacceptable
1279 ports from printing the limit-connect argument as [null] if
1280 limit-connect hasn't been explicitly enabled.
1281 - Don't disable the mingw32 log window if the logfile directive
1282 isn't used. While it was an intentional change in 3.0.7 at least
1283 one user perceived it as a regression and the same effect can
1284 be achieved by disabling all debug directives.
1285 - Fixed two minor problems related to the win32 build process: a css
1286 file was not being in the installer and the trustfile comment in the
1287 config.txt referenced a nonexisting file
1288 - Minor documentation fixes.
1290 *** Version 3.0.7 beta ***
1292 - Added zlib support to filter content with gzip and deflate
1293 encoding. (Patch provided by Wil Mahan)
1294 - Dedicated filters and actions are used for header filtering.
1295 "filter-client-headers" and "filter-client-headers" are no longer
1296 supported, use server-header-filter{} and client-header-filter{}
1298 - Tags can be used to change actions based on HTTP headers.
1299 - New server-header filter: less-download-windows.
1300 - New client-header taggers: css-requests, image-requests,
1301 client-ip-address, http-method, allow-post, complete-url,
1302 user-agent and privoxy-control.
1303 - New server-header taggers: content-type and privoxy-control.
1304 - The forward-override{} action allows to change the forwarding
1305 settings through the action files, for example based on client
1306 headers like the User-Agent, or the request origin.
1307 - Socks errors are no longer handled by the CGI page for
1308 DNS resolution failures.
1309 - CGI pages use favicons to signal whether they are error
1310 or control pages. This is useful if you rely heavily on
1312 - The show-url-info CGI page shows the forwarding settings.
1313 - "Crunch!" log messages (used when Privoxy answers requests
1314 by itself) now also contain the reason.
1315 - Allow to rewrite the request destination behind the client's back.
1316 - Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
1317 - Fixes possible deadlocks and crashes on OpenBSD.
1318 Patch provided by Ralf Horstmann.
1319 - The CGI action editor allows to edit actionfiles with previously
1320 forbidden characters like dots.
1321 - New trust entries are saved with a comment that contains the
1322 trusted referring URL (Suggested by Daniel Griscom).
1323 - Filter descriptions are HTML encoded automatically.
1324 - New config option "split-large-forms" to work
1325 around a browser bug that caused IE6 and IE7 to ignore
1326 the Submit button on the edit-actions-for-url CGI page.
1327 - New config option "allow-cgi-request-crunching" to allow
1328 requests for Privoxy's CGI pages to be blocked, redirected
1329 or (un)trusted like ordinary requests.
1330 - Empty filter files no longer interrupt the filtering process
1331 prematurely and are correctly listed on the show-status CGI page.
1332 - New config option "accept-intercepted-requests" to combine
1333 Privoxy with any packet filter to build an intercepting proxy
1334 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
1335 - fast-redirects{} catch redirects to https URLs as well.
1336 - redirect{s@foo@bar@} can be used to redirect to a rewritten
1337 version of the original URL.
1338 - Trap unsupported gopher proxy requests.
1339 - Fixed a bug in the User Manual delivery on Windows
1340 (mingw32 only). Images now show up correctly and HTML
1341 pages are no longer padded with garbage data.
1342 - Fixed several minor memory leaks, most of them discovered with Valgrind.
1343 - Only unlink the pidfile if it's actually used.
1344 - Retries after connection problems with forced requests
1345 aren't blocked again.
1346 - On Unix SIGABRT causes a core dump as expected and is no
1347 longer treated as normal shutdown signal.
1348 - The "access denied" CGI page is more descriptive and
1349 allows retries to circumvent the referrer check.
1350 - Updated PCRS to handle unexpected PCRE errors properly.
1351 Fixed crashes that could occur if Privoxy was build
1352 with external PCRE versions newer than Privoxy's internal
1353 one. (Reported by Chung-chieh Shan)
1354 - Fixed crashes with null bytes in PCRS replacement strings
1355 (Patch provided by Felix Gröbert).
1356 - Fixed crashes with header time randomization on mingw32.
1357 - The CGI style sheet is no longer delivered if the referring
1358 page isn't a Privoxy CGI page. This prevents a JavaScript-based
1359 Privoxy detection "attack". Note that detecting Privoxy is
1360 still possible through other ways and Privoxy was never intended
1361 to be invisible anyway.
1362 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
1363 - The show-url-info CGI page displays a warning if Privoxy
1364 is currently toggled off.
1365 - The show-status CGI page suppresses the edit button
1366 for action files if Privoxy has no write access.
1367 - Most CGI error pages react properly to HEAD requests.
1368 - Requests with RFC 3253 HTTP methods (used by Subversion)
1369 are accepted. (Patch provided by Petr Kadlec)
1370 - New config option "templdir" to change the location
1371 of the CGI templates to make sure customized templates
1373 - Better handling of "HTTP/1.1 100 Continue" responses.
1374 - The background of the PNG pattern is transparent.
1375 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
1376 - Fixed crashes and possible action file corruptions
1377 when lines containing hashes are written through the CGI editor.
1378 - Supports dynamic filters which can contain variables.
1379 - Supports tags to change the actions based on client or server headers.
1380 - Incorrect actions are logged before program termination.
1381 - The "actionsfile" syntax in the configuration file is consistent
1382 with the rest of the configuration options and requires the
1383 whole file name. This is an incompatible change, if you use
1384 an old configuration file you might have to append ".action"
1385 to your "actionsfile" directives.
1386 - With the configuration file option "enforce-blocks" the
1387 "go there anyway" mechanism can be disabled without recompiling
1389 - More precise error messages in case of incorrect acl syntax.
1390 - Logs a warning if filtering is enabled but impossible due
1391 to lack of zlib support or use of the prevent-compression action.
1392 - Less noisy handling of Cookie:" and "Connection:" headers.
1393 - Improved error messages in case of connection problems.
1394 - Fix a command-line-parsing bug that was introduced before 3.0.5
1395 beta and caused Privoxy to treat the last argument as configuration
1396 file if no configuration file was specified.
1397 - Treat unknown command line options as fatal errors instead
1398 of silently ignoring them.
1399 - Use string functions with length checks more often.
1400 - Don't log CONNECT requests twice.
1401 - Allow to log the source address for ACL-related connection drops.
1402 - Don't ignore applying filters if the server didn't
1403 specify a Content-Type. Bug reported by Amuro Namie.
1404 - Rejected CONNECT requests are logged with log level info
1405 (enabled by default) and the reason for the block.
1406 - New command line option "--pre-chroot-nslookup hostname" to
1407 intialize the resolver library before chroot'ing. On some systems this
1408 reduces the number of files that must be copied into the chroot tree.
1409 (Patch provided by Stephen Gildea)
1410 - Fix a long-standing memory corruption bug that could cause
1411 Privoxy to overwrite a single byte in memory it didn't explicitly
1412 allocate (but that probably was allocated anyway due to bucket size).
1413 - Send template-based CGI pages as HTTP/1.1 unless the client
1415 - Let the first line in connection established responses
1416 end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
1417 - If no log file has been specified, disable logging instead of logging
1419 - Don't block stderr when in daemon mode.
1420 - Ignore missing zero-chunks when filtering chunk-encoded content.
1421 Earlier Privoxy versions would buffer and then forward the content
1422 unmodified which caused some browsers to simply show empty pages.
1423 - Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
1424 - The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
1425 action isn't being used has been removed.
1426 - Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
1428 - Minor code clean-ups, filter and action file updates.
1429 (Some of them reported by Davide Alberani, Markus Elfring,
1430 Stefan Huehner and Adam Piggott)
1432 *** Version 3.0.6 ***
1434 - New content filters: no-ping, google, msn, yahoo and blogspot.
1435 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
1436 and hide-tor-exit-notation.
1437 - The special header "X-Filter: No" now disables header filtering as well.
1438 - Improved the filters img-reorder, js-annoyances, webbugs,
1439 banners-by-size, banners-by-link and ie-exploits to make them
1440 less likely to break anything.
1441 - Removed outdated URL patterns in default.action and added new ones.
1442 - Added redirection from http://p.p/user-manual to http://p.p/user-manual/

1452 following new or significantly improved actions (among many
1453 other improvements):
1455 content-type-overwrite{}
1456 crunch-client-header{string}
1457 crunch-if-none-match
1458 crunch-server-header{string}
1459 fast-redirects{check-decoded-url}
1460 filter-client-headers
1461 filter-server-headers
1463 handle-as-empty-document
1464 hide-accept-language{}
1465 hide-content-disposition{}

1495 - Fixed yet another two memory leaks. Process growth seems stopped now.
1496 - Further tightened security against malicious toggle-off links.
1497 - Excluded text/plain MIME types from filtering. This fixes a
1498 couple of client-crashing, download corruption and
1499 Privoxy performance issues, whose root cause lies in
1500 web servers labelling content of unknown type as text/plain.
1501 - Assorted fixes for POSIX compliance, signal handling, graceful
1502 termination, compiler warnings, OSX support, Win32 systray,
1503 error logging, hostname wildcards, correct detection of NetBSD.
1504 - Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs

1523 - Replaced filter "popups" by choice between two modes:
1524 - "unsolicited-popups" tries to catch only the unsolicited ones

1526 - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
1527 - New filter "jumping-windows" that prevents windows from resizing
1528 and moving themselves

1532 all filters for exploits shall be collected
1533 - Improved cookie logging
1534 - Rewrote make install target. Added uninstall and install-strip

1588 - Various other minor fixes.
1590 *** Version 2.9.13 beta ***
1592 - *NEWS*: The project has been renamed to Privoxy! The new name is
1593 reflected throughout (file locations, etc).
1594 - ijb.action is now default.action. re_filterfile is now

1669 *** Version 2.9.3 pre-Alpha Changes ***
1671 - Amiga support (completely untested by me - I don't have an Amiga)
1672 - "tinygif 3" support (redirects blocked images to a specified URL, so
1673 the browser doesn't have to load and cache many copies of the same
1675 - one case where there were both local and global "referrer" variables
1676 (yuck!) clarified by renaming the local one to "refer".
1677 - Fixed some places where close() was used instead of close_socket().
1678 Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
1679 - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
1680 FORCE_LOAD_PREFIX. Needs fixing properly.
1681 - Most URLs hardcoded into Junkbuster were changed to go through a script
1682 e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
1683 The only other URLs left are the GNU GPL:
1684 http://www.fsf.org/copyleft/gpl.html
1686 http://ijbswa.sourceforge.net/
1687 ... and various URLs which will be intercepted by Junkbuster anyway.
1688 TODO: Still need to do something with the URLs in Junkbuster Corp's
1689 copyright/trademark notice on the bottom of the show-proxy-args page.
1690 - PCRE or GNU Regex is now a #define option.
1693 *** Version 2.9.2 pre-Alpha Changes ***
1695 - Andreas applied the latest version of the FORCE patch.
1698 *** Version 2.9.1 pre-Alpha Changes ***
1700 - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
1701 (BTW: I think FORCE is precise enough, since loading remote
1702 data is the whole purpose of a proxy..)
1703 - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
1704 is more elegant and looks like a hostname in the URL, it doesn't
1705 make clear to the inexperienced user that the proxy is bypassed. It
1706 also has a higher name collision risk.
1707 - Filled in the function header templates for my functions in
1708 parsers.c (again). They obviously got lost in our current
1710 - Cut the credit for the §-referrer-option from the config file,
1711 that Stefan had placed there.
1712 - Improved the re_filterfile
1715 *** Version 2.9.0 pre-Alpha Changes ***
1717 - Now use PCRE, not GNU REGEX. I have not yet had chance to check the
1718 syntax of the block/image/cookie file to ensure that they match what
1719 is expected - however they seem to work.
1720 - Replaced "configure" script with one generated by "autoconf". Also
1721 use a header "config.h" (was ijbconfig.h in my previous release) for
1722 the #defines. "config.h" is now generated with "autoheader" from
1723 "acconfig.h" and "configure.in". (Note that to install you do not
1724 need autoconf or autoheader - just run "./configure".)
1725 To see command-line options, run "./configure --help".
1726 This is my first ever autoconf script, so it has some rough edges
1727 (how PCRE is handled is the roughest).
1728 - Error logging code replaced with new module errlog.c, based on the
1729 one from JunkbusterMT (but with the threading code removed).
1730 - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
1731 apply all of these, since I had already independently done conditional
1732 popup file, conditional image file, and integration of popup code.
1733 - ACL, Jar and trust files conditionally compiled.
1734 - New source file headers.
1735 - Various cosmetic changes. (But I have not consistently ordered the
1736 config files - I think that's worthwhile, but it's 1am and I want to
1738 - RCS tags on .h files.
1739 - RCS tags are const char[] rather than const char *. (Saves 4 bytes
1741 - VC++ project files renamed to vc_junkbuster.*.
1742 - show-proxy-args now shows status of all conditionals, not just REGEX
1743 - Various functions moved around. Most notably all the system-specific
1744 sockets code which was spread between jcc.c, bind.c, and connect.c,
1745 has been moved to "jbsockets.c". The non-system-specific code from
1746 connect.c and socks4.c has been movet to "gateway.c". Also, the
1747 config file loader and the global variables it writes to have been
1748 moved to "loadcfg.c". (Maybe this should go into loaders.c?)
1749 And candidate for the "worst filename ever" award is "miscutil.c",
1750 which contains, well, miscellaneous utility functions like zalloc.
1751 (Suggestions for a better name for this file are welcome!)
1752 - Loaders now use a common function to read a line and skip comments,
1753 and this function also stores the proxy_args.
1754 - Added ./junkbuster --help (Not for Win32 GUI)
1755 - Added ./junkbuster --version (Not for Win32 GUI)
1756 - Win32 resources are now all marked as "U.S. English", rather than
1757 being a mix of "U.S. English", "U.K. English" and "Irish English".
1758 - Version number changes to 2.9.0
