4 *** Version 3.0.18 Stable ***
7 - Fix a logic bug that could cause Privoxy to reuse a server
8 socket after it got tainted by a server-header-tagger-induced
9 block that was triggered before the whole server response had
10 been read. If keep-alive was enabled and the request following
11 the blocked one was to the same host and using the same forwarding
12 settings, Privoxy would send it on the tainted server socket.
13 While the server would simply treat it as a pipelined request,
14 Privoxy would later on fail to properly parse the server's
15 response as it would try to parse the unread data from the
16 first response as server headers for the second one.
17 Regression introduced in 3.0.17.
18 - When implying keep-alive in client_connection(), remember that
19 the client didn't. Fixes a regression introduced in 3.0.13 that
20 would cause Privoxy to wait for additional client requests after
21 receiving a HTTP/1.1 request with "Connection: close" set
22 and connection sharing enabled.
23 With clients which terminates the client connection after detecting
24 that the whole body has been received it doesn't really matter,
25 but with clients that don't the connection would be kept open until
27 - Fix a subtle race condition between prepare_csp_for_next_request()
28 and sweep() A thread preparing itself for the next client request
29 could briefly appear to be inactive.
30 If all other threads were already using more recent files,
31 the thread could get its files swept away under its feet.
32 So far this has only been reproduced while stress testing in
33 valgrind while touching action files in a loop. It's unlikely
34 to have caused any actual problems in the real world.
35 - Disable filters if SDCH compression is used unless filtering is forced.
36 If SDCH was combined with a supported compression algorithm, Privoxy
37 previously could try to decompress it and ditch the Content-Encoding
38 header even though the SDCH compression wasn't dealt with.
39 Reported by zebul666 in #3225863.
40 - Make a copy of the --user value and only mess with that when splitting
41 user and group. On some operating systems modifying the value directly
42 is reflected in the output of ps and friends and can be misleading.
43 Reported by zepard in #3292710.
44 - If forwarded-connect-retries is set, only retry if Privoxy is actually
45 forwarding the request. Previously direct connections would be retried
47 - Fixed a small memory leak when retrying connections with IPv6
49 - Remove an incorrect assertion in compile_dynamic_pcrs_job_list()
50 It could be triggered by a pcrs job with an invalid pcre
51 pattern (for example one that contains a lone quantifier).
52 - If the --user argument user[.group] contains a dot, always bail out
53 if no group has been specified. Previously the intended, but undocumented
54 (and apparently untested), behaviour was to try interpreting the whole
55 argument as user name, but the detection was flawed and checked for '0'
56 instead of '\0', thus merely preventing group names beginning with a zero.
57 - In html_code_map[], use a numeric character reference instead of '
58 which wasn't standardized before XHTML 1.0.
59 - Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION
60 and shut down through http://config.privoxy.org/die
61 - In get_actions(), fix the "temporary" backwards compatibility hack
62 to accept block actions without reason.
63 It also covered other actions that should be rejected as invalid.
64 Reported by Billy Crook.
66 - General improvements:
67 - Privoxy can (re)compress buffered content before delivering
68 it to the client. Disabled by default as most users wouldn't
70 - The +fast-redirects{check-decoded-url} action checks URL
71 segments separately. If there are other parameters behind
72 the redirect URL, this makes it unnecessary to cut them off
73 by additionally using a +redirect{} pcrs command.
74 Initial patch submitted by Jamie Zawinski in #3429848.
75 - When loading action sections, verify that the referenced filters
76 exist. Currently missing filters only result in an error message,
77 but eventually the severity will be upgraded to fatal.
78 - Allow to bind to multiple separate addresses.
79 Patch set submitted by Petr Pisar in #3354485.
80 - Set socket_error to errno if connecting fails in rfc2553_connect_to()
81 Previously rejected direct connections could be incorrectly reported
82 as DNS issues if Privoxy was compiled with IPv6 support.
83 - Adjust url_code_map[] so spaces are replaced with %20 instead of '+'
84 While '+' can be used by client's submitting form data, this is not
85 actually what Privoxy is using the lookups for. This is more of a
86 cosmetic issue and doesn't fix any known problems.
87 - When compiled without FEATURE_FAST_REDIRECTS, do not silently
88 ignore +fast-redirect{} directives
89 - Added a workaround for GNU libc's strptime() reporting negative
90 year values when the parsed year is only specified with two digits.
91 On affected systems cookies with such a date would not be turned
92 into session cookies by the +session-cookies-only action.
93 Reported by Vaeinoe in #3403560
94 - Fixed bind failures with certain GNU libc versions if no non-loopback
95 IP address has been configured on the system. This is mainly an issue
96 if the system is using DHCP and Privoxy is started before the network
97 is completely configured.
98 Reported by Raphael Marichez in #3349356.
99 Additional insight from Petr Pisar.
100 - Privoxy log messages now use the ISO 8601 date format %Y-%m-%d.
101 It's only slightly longer than the old format, but contains
102 the full date including the year and allows sorting by date
103 (when grepping in multiple log files) without hassle.
104 - In get_last_url(), do not bother trying to decode URLs that do
105 not contain at least one '%' sign. It reduces the log noise and
106 a number of unnecessary memory allocations.
107 - In case of SOCKS5 failures, dump the socks response in the log message.
108 - Simplify the signal setup in main()
109 - Streamline socks5_connect() slightly
110 - In socks5_connect(), require a complete socks response from the server
111 Previously Privoxy didn't care how much data the server response
112 contained as long as the first two bytes contained the expected
113 values. While at it, shrink the buffer size so Privoxy can't read
114 more than a whole socks response.
115 - In chat(), do not bother to generate a client request in case of
116 direct CONNECT requests. It will not be used anyway.
117 - Reduce server_last_modified()'s stack size.
118 - Shorten get_http_time() by using strftime().
119 - Constify the known_http_methods pointers in unknown_method().
120 - Constify the time_formats pointers in parse_header_time().
121 - Constify the formerly_valid_actions pointers in action_used_to_be_valid().
122 - Introduce a GNUMakefile MAN_PAGE variable that defaults to privoxy.1.
123 The Debian package uses section 8 for the man page and this
124 should simplify the patch.
125 - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
126 - In block_url(), ditch the obsolete workaround for ancient Netscape versions
127 that supposedly couldn't properly deal with status code 403.
128 - Remove a useless NULL pointer check in load_trustfile().
129 - Remove two useless NULL pointer checks in load_one_re_filterfile().
130 - Change url_code_map[] from an array of pointers to an array of arrays
131 It removes an unnecessary layer of indirection and on 64bit system reduces
132 the size of the binary a bit.
133 - Fix various typos. Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
134 - Add a dok-tidy GNUMakefile target to clean up the messy HTML
135 generated by the other dok targets.
136 - GNUisms in the GNUMakefile have been removed.
137 - Change the HTTP version in static responses to 1.1
138 - Synced config.sub and config.guess with upstream
139 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
140 - Add a dedicated function to parse the values of toggles. Reduces duplicated
141 code in load_config() and provides better error handling. Invalid or missing
142 toggle values are now a fatal error instead of being silently ignored.
143 - Terminate HTML lines in static error messages with \n instead of \r\n.
144 - Simplify cgi_error_unknown() a bit.
145 - In LogPutString(), don't bother looking at pszText when not
146 actually logging anything.
147 - Change ssplit()'s fourth parameter from int to size_t.
148 Fixes a clang complaint.
149 - Add a warning that the statistics currently can't be trusted.
150 Mention Privoxy-Log-Parser's --statistics option as
151 an alternative for the time being.
152 - In rfc2553_connect_to(), start setting cgi->error_message on error
153 - Change the expected status code returned for http://p.p/die depending
154 on whether or not FEATURE_GRACEFUL_TERMINATION is available.
155 - In cgi_die(), mark the client connection for closing.
156 If the client will fetch the style sheet through another connection
157 it gets the main thread out of the accept() state and should thus
158 trigger the actual shutdown.
159 - Add a proper CGI message for cgi_die().
160 - Don't enforce a logical line length limit in read_config_line()
161 - Slightly refactor server_last_modified() to remove useless gmtime*() calls
162 - In get_content_type(), also recognize '.jpeg' as JPEG extension
163 - Add '.png' to the list of recognized file extenstions in get_content_type()
164 - In block_url(), consistently use the block reason "Request blocked by Privoxy"
165 In two places the reason was "Request for blocked URL" which hides the
166 fact that the request got blocked by Privoxy and isn't necessarily
167 correct as the block may be due to tags.
168 - In listen_loop(), reload the configuration files after accepting
169 a new connection instead of before.
170 Previously the first connection that arrived after a configuration
171 change would still be handled with the old configuration.
172 - In chat()'s receive-data loop, skip a client socket check if
173 the socket will be written to right away anyway. This can
174 increase the transfer speed for unfiltered content on fast
176 - The socket timeout is used for SOCKS negotiations as well which
177 previously couldn't timeout.
178 - Don't keep the client connection alive if any configuration file
179 changed since the time the connection came in. This is closer to
180 Privoxy's behaviour before keep-alive support for client connection
181 has been added and also less confusing in general.
182 - Treat all Content-Type header values containing the pattern
183 'script' as a sign of text. Reported by pribog in #3134970.
186 - Action file improvements:
187 - Moved the site-specific block pattern section below the one for the
188 generic patterns so for requests that are matched in both, the block
189 reason for the domain is shown which is usually more useful than showing
190 the one for the generic pattern.
191 - Remove -prevent-compression from the fragile alias It's no longer
192 used anywhere by default and isn't known to break stuff anyway.
193 - Add a (disabled) section to block various Facebook tracking URLs
194 Reported by Dan Stahlke in #3421764.
195 - Add a (disabled) section to rewrite and redirect click-tracking
196 URLs used on news.google.com
197 Reported by Dan Stahlke in #3421755.
198 - Unblock linuxcounter.net/
199 Reported by Dan Stahlke in #3422612.
200 - Block 'www91.intel.com/' which is used by Omniture.
201 Reported by Adam Piggott in #3167370.
202 - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
203 Reminded by tceverling in #2790091.
204 - Add ".ivwbox.de/" to the "Cross-site user tracking" section.
205 Reported by Nettozahler in #3172525.
206 - Unblock and fast-redirect ".awin1.com/.*=http://"
207 Reported by Adam Piggott in #3170921.
208 - Block "b.collective-media.net/".
209 - Widen the Debian popcon exception to "qa.debian.org/popcon".
210 Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
211 - Block ".gemius.pl/" which only seems to be used for user tracking.
212 Reported by johnd16 in #3002731. Additional input from Lee and movax.
213 - Disable banners-by-size filters for '.thinkgeek.com/'
214 The filter only seems to catch pictures of the inventory.
215 - Block requests for 'go.idmnet.bbelements.com/please/showit/'
216 Reported by kacperdominik in #3372959.
217 - Unblock adainitiative.org/
218 - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'
219 - Add a fast-redirects exception for webcache.googleusercontent.com/
220 - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/
222 - Filter file improvements:
223 - Let the yahoo filter hide '.ads'
224 - Let the msn filter hide overlay ads for Facebook 'likes' in search
225 results and elements with the id 's_notf_div'. They only seem to be
226 used to advertise site 'enhancements'.
227 - Let the js-events filter additionally disarm setInterval()
228 Suggested by dg1727 in #3423775.
230 - Documentation improvements:
231 - Clarify the effect of compiling Privoxy with zlib support
232 Suggested by dg1727 in #3423782.
233 - Point out that the SourceForge messaging system works like a black
234 hole and should thus not be used to contact individual developers.
235 - Mention some of the problems one can experience when not explicitly
236 configuring an IP addresses as listen address.
237 - Explicitly mention that hostnames can be used instead of IP addresses
238 for the listen-address, that only the first address returned will be
239 used and what happens if the address is invalid.
240 Requested by Calestyo in #3302213.
242 - Log message improvements:
243 - If only the server connection is kept alive, do not pretent to
244 wait for a new client request.
245 - Remove a superfluos log message in forget_connection()
246 - In chat(), properly report missing server responses as such
247 instead of calling them empty
248 - In forwarded_connect(), fix a log message nobody should ever see
249 - Fix a log message in socks5_connect(), a failed write operation
250 was logged as failed read operation
251 - Let load_one_actions_file() properly complain about a missing
252 '{' at the beginning of the file
253 Simply stating that a line is invalid isn't particularly helpful.
254 - Do not claim to listen on a socket until Privoxy actually does.
255 Patch submitted by Petr Pisar #3354485
256 - Prevent a duplicated LOG_LEVEL_CLF message when sending out
257 the "no-server-data" response
258 - Also log the client socket when dropping a connection.
259 - Include the destination host in the 'Request ... marked for
260 blocking. limit-connect{...} doesn't allow CONNECT ...' message
261 Patch submitted by Saperski in #3296250.
262 - Prevent a duplicated log message if none of the resolved IP
263 addresses were reachable
264 - In connect_to(), do not pretend to retry if forwarded-connect-retries
266 - When a specified user or group can't be found, put the name in
267 single-quotes when logging it.
268 - In rfc2553_connect_to(), explain getnameinfo() errors better.
269 - Remove a useless log message in chat()
270 - When retrying to connect, also log the maximum number of connection
272 - Rephrase a log message in compile_dynamic_pcrs_job_list().
273 Divide the error code and its meaning with a colon. Call the pcrs
274 job dynamic and not the filter. Filters may contain dynamic and
275 non-dynamic pcrs jobs at the same time. Only mention the name of
276 the filter or tagger, but don't claim it's a filter when it could
278 - In a fatal error message in load_one_actions_file(), cover both
279 URL and TAG patterns.
280 - In pcrs_strerror(), properly report unknown positive error code
281 values as such. Previously they were handled like 0 (no error).
282 - In compile_dynamic_pcrs_job_list(), also log the actual error code as
283 pcrs_strerror() doesn't handle all errors reported by pcre
284 - Don't bother trying to continue chatting if the client didn't ask for it.
285 Reduces log noise a bit.
286 - Make two fatal error message in load_one_actions_file() more descriptive
287 - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'
288 - In load_file(), log a message if opening a file failed
289 The CGI error message alone isn't too helpful.
290 - In connection_destination_matches(), improve two log messages
291 to help understand why the destinations don't match.
292 - Rephrase a log message in serve(). Client request arrival
293 should be differentiated from closed client connections now.
294 - In serve(), log if a client connection isn't reused due to a
295 configuration file change.
296 - Let mark_server_socket_tainted() always mark the server socket tainted,
297 just don't talk about it in cases where it has no effect. It doesn't change
298 Privoxy's behaviour, but makes understanding the log file easier.
301 - Added a --disable-ipv6-support switch for platforms where support
302 is detected but doesn't actually work.
303 - Do not check for the existence of strerror() and memmove() twice
304 - Remove a useless test for setpgrp(2). Privoxy doesn't need it and
305 it can cause problems when cross-compiling.
306 - Rename the --disable-acl-files switch to --disable-acl-support.
307 Since about 2001, ACL directives are specified in the standard
309 - Update the URL of the 'Removing outdated PCRE version after the
310 next stable release' posting. The old URL stopped working after
311 one of SF's recent site "optimizations". Reported by Han Liu.
313 - Privoxy-Regression-Test:
314 - Added --shuffle-tests option to increase the chances of detection race conditions.
315 - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy
316 - Added tests for missing socks4 and socks4a forwarders
317 - The --privoxy-address option now works with IPv6 addresses containing brackets, too
318 - Perform limited sanity checks for parameters that are supposed to have numerical values.
319 - Added a --sleep-time option to specify a number of seconds to
320 sleep between tests, defaults to 0.
321 - Disable the range-requests tagger for tests that break if it's enabled
322 - Log messages use the ISO 8601 date format %Y-%m-%d.
323 - Fix spelling in two error messages.
324 - In the --help output, include a list of supported tests and their default levels.
325 - Adjust the tests to properly deal with FEATURE_TOGGLE being disabled.
327 - Privoxy-Log-Parser:
328 - Perform limited sanity checks for command line parameters that
329 are supposed to have numerical values.
330 - Implement a --unbreak-lines-only option to try to revert MUA breakage.
331 - Accept and highlight: Added header: Content-Encoding: deflate
332 - Accept and highlight: Compressed content from 29258 to 8630 bytes.
333 - Accept and highlight: Client request arrived in time on socket 21.
334 - Highlight: Didn't receive data in time: a.fsdn.com:443
335 - Accept log messages with ISO 8601 time stamps, too
338 - Bump generated Firefox version to 8.0
339 - Only randomize the release date if the new --randomize-release-date
340 option is enabled. Firefox versions after 4 use a fixed date string
344 *** Version 3.0.17 Stable ***
346 - Fixed last-chunk-detection for responses where the body was small
347 enough to be read with the headers, causing Privoxy to wait for the
348 end of the content until the server closed the connection or the
349 request timed out. Reported by "Karsten" in #3028326.
350 - Responses with status code 204 weren't properly detected as body-less
351 like RFC2616 mandates. Like the previous bug, this caused Privoxy to
352 wait for the end of the content until the server closed the connection
353 or the request timed out. Fixes #3022042 and #3025553, reported by a
354 user with no visible name. Most likely also fixes a bunch of other
355 AJAX-related problem reports that got closed in the past due to
356 insufficient information and lack of feedback.
357 - Fixed an ACL bug that made it impossible to build a blacklist.
358 Usually the ACL directives are used in a whitelist, which worked
359 as expected, but blacklisting is still useful for public proxies
360 where one only needs to deny known abusers access.
361 - Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
362 network. This should make debugging various parsing issues a lot easier.
363 - The IPv6 code is enabled by default on Windows versions that support it.
364 Patch submitted by oCameLo in #2942729.
365 - In mingw32 versions, the user.filter file is reachable through the
366 GUI, just like default.filter is. Feature request 3040263.
367 - Added the configure option --enable-large-file-support to set a few
368 defines that are required by platforms like GNU/Linux to support files
369 larger then 2GB. Mainly interesting for users without proper logfile
371 - Logging with "debug 16" no longer stops at the first nul byte which is
372 pretty useless. Non-printable characters are replaced with their hex value
373 so the result can't span multiple lines making parsing them harder then
375 - Privoxy logs when reading an action, filter or trust file.
376 - Fixed incorrect regression test markup which caused a test in
377 3.0.16 to fail while Privoxy itself was working correctly.
378 While Privoxy accepts hide-referer, too, the action name is actually
379 hide-referrer which is also the name used one the final results page,
380 where the test expected the alias.
382 - CGI interface improvements:
383 - In finish_http_response(), continue to add the 'Connection: close'
384 header if the client connection will not be kept alive.
385 Anonymously pointed out in #2987454.
386 - Apostrophes in block messages no longer cause parse errors
387 when the blocked page is viewed with JavaScript enabled.
388 Reported by dg1727 in #3062296.
389 - Fix a bunch of anchors that used underscores instead of dashes.
390 - Allow to keep the client connection alive after crunching the previous request.
391 Already opened server connections can be kept alive, too.
392 - In cgi_show_url_info(), don't forget to prefix URLs that only contain
393 http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott.
394 - Show the 404 CGI page if cgi_send_user_manual() is called while
395 local user manual delivery is disabled.
397 - Action file improvements:
398 - Enable user.filter by default. Suggested by David White in #3001830.
399 - Block .sitestat.com/. Reported by johnd16 in #3002725.
400 - Block .atemda.com/. Reported by johnd16 in #3002723.
401 - Block js.adlink.net/. Reported by johnd16 in #3002720.
402 - Block .analytics.yahoo.com/. Reported by johnd16 in #3002713.
403 - Block sb.scorecardresearch.com, too. Reported by dg1727 in #2992652.
404 - Fix problems noticed on Yahoo mail and news pages.
405 - Remove the too broad yahoo section, only keeping the
406 fast-redirects exception as discussed on ijbswa-devel@.
407 - Don't block adesklets.sourceforge.net. Reported in #2974204.
408 - Block chartbeat ping tracking. Reported in #2975895.
409 - Tag CSS and image requests with cautious and medium settings, too.
410 - Don't handle view.atdmt.com as image. It's used for click-throughs
411 so users should be able to "go there anyway".
412 Reported by Adam Piggott in #2975927.
413 - Also let the refresh-tags filter remove invalid refresh tags where
414 the 'url=' part is missing. Anonymously reported in #2986382.
415 While at it, update the description to mention the fact that only
416 refresh tags with refresh times above 9 seconds are covered.
417 - javascript needs to be blocked with +handle-as-empty-document to
418 work around Firefox bug 492459. So move .js blockers from
419 +block{Might be a web-bug.} -handle-as-empty-document to
420 +block{Might be a web-bug.} +handle-as-empty-document.
421 - ijbswa-Feature Requests-3006719 - Block 160x578 Banners.
422 - Block another omniture tracking domain.
423 - Added a range-requests tagger.
424 - Added two sections to get Flickr's Ajax interface working with
425 default pre-settings. If you change the configuration to block
426 cookies by default, you'll need additional exceptions.
427 Reported by Mathias Homann in #3101419 and by Patrick on ijbswa-users@.
429 - Documentation improvements:
430 - Explicitly mention how to match all URLs.
431 - Consistently recommend socks5 in the Tor FAQ entry and mention
432 its advantage compared to socks4a. Reported by David in #2960129.
433 - Slightly improve the explanation of why filtering may appear
435 - Grammar fixes for the ACL section.
436 - Fixed a link to the 'intercepting' entry and add another one.
437 - Rename the 'Other' section to 'Mailing Lists' and reword it
438 to make it clear that nobody is forced to use the trackers
439 - Note that 'anonymously' posting on the trackers may not always
441 - Suggest to enable debug 32768 when suspecting parsing problems.
443 - Privoxy-Log-Parser improvements:
444 - Gather statistics for ressources, methods, and HTTP versions
446 - Also gather statistics for blocked and redirected requests.
447 - Provide the percentage of keep-alive offers the client accepted.
448 - Add a --url-statistics-threshold option.
449 - Add a --host-statistics-threshold option to also gather
450 statistics about how many request where made per host.
451 - Fix a bug in handle_loglevel_header() where a 'scan: ' got lost.
452 - Add a --shorten-thread-ids option to replace the thread id with
454 - Accept and ignore: Looks like we got the last chunk together
455 with the server headers. We better stop reading.
456 - Accept and ignore: Continue hack in da house.
457 - Accept and higlight: Rejecting connection from 10.0.0.2.
458 Maximum number of connections reached.
459 - Accept and highlight: Loading actions file: /usr/local/etc/privoxy/default.action
460 - Accept and highlight: Loading filter file: /usr/local/etc/privoxy/default.filter
461 - Accept and highlight: Killed all-caps Host header line: HOST: bestproxydb.com
462 - Accept and highlight: Reducing expected bytes to 0. Marking
463 the server socket tainted after throwing 4 bytes away.
464 - Accept: Merged multiple header lines to: 'X-FORWARDED-PROTO: http X-HOST: 127.0.0.1'
467 - Remove the next member from the client_state struct. Only the main
468 thread needs access to all client states so give it its own struct.
469 - Garbage-collect request_contains_null_bytes().
470 - Ditch redundant code in unload_configfile().
471 - Ditch LogGetURLUnderCursor() which doesn't seem to be used anywhere.
472 - In write_socket(), remove the write-only variable write_len in
473 an ifdef __OS2__ block. Spotted by cppcheck.
474 - In connect_to(), don't declare the variable 'flags' on OS/2 where
475 it isn't used. Spotted by cppcheck.
476 - Limit the scope of various variables. Spotted by cppcheck.
477 - In add_to_iob(), turn an interestingly looking for loop into a
479 - Code cleanup in preparation for external filters.
480 - In listen_loop(), mention the socket on which we accepted the
481 connection, not just the source IP address.
482 - In write_socket(), also log the socket we're writing to.
483 - In log_error(), assert that escaped characters get logged
484 completely or not at all.
485 - In log_error(), assert that ival and sval have reasonable values.
486 There's no reason not to abort() if they don't.
487 - Remove an incorrect cgi_error_unknown() call in a
488 cannot-happen-situation in send_crunch_response().
489 - Clean up white-space in http_response definition and
490 move the crunch_reason to the beginning.
491 - Turn http_response.reason into an enum and rename it
492 to http_response.crunch_reason.
493 - Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686 GNU/Linux.
494 - Fix white-space in a log message in remove_chunked_transfer_coding().
495 While at it, add a note that the message doesn't seem to
496 be entirely correct and should be improved later on.
498 - GNUmakefile improvements:
499 - Use $(SSH) instead of ssh, so one only needs to specify a username once.
500 - Removed references to the action feedback thingy that hasn't been
502 - Consistently use shell.sourceforge.net instead of shell.sf.net so
503 one doesn't need to check server fingerprints twice.
504 - Removed GNUisms in the webserver and webactions targets so they
505 work with standard tar.
507 *** Version 3.0.16 Stable ***
509 - Added the config file option handle-as-empty-doc-returns-ok to
510 work around Firefox bug #492459, which causes Firefox to hang
511 if JavaScripts are blocked in certain situations. The option is
512 enabled in the default config file.
513 - Added the config file option default-server-timeout to control the
514 assumed default server timeout. Since Privoxy no longer returns
515 an error message for connection resets on reused client connections,
516 assuming larger server timeout values appears to actually work
517 pretty well as long as connections aren't shared.
518 - Added optional support for FreeBSD's accf_http(9). Use the
519 configure option --enable-accept-filter to enable it.
520 - Added fancier Privoxy icons for win32. Contributed by Jeff H.
521 - In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
522 - Resolve localhost using whatever address family the operating
523 system feels like. Previous betas would try to use IPv4 as this
524 is what most users expect, but this didn't work reliably on
526 - In the action lists on CGI pages, actions and their parameters are
527 no longer separated with a space. The action file parser doesn't
528 actually allow this and will throw an invalid syntax error if actions
529 and parameters in the action files are separated. Not adding the
530 spaces means copy and pasting CGI output into the action files works.
531 - The default keep-alive timeout has been reduced to 5 seconds to work
532 around hangs in clients that treat the proxy like any other host and
533 stop allowing any new connections if the "maximum number of
534 connections per host" is reached.
535 - Several webbug URLs that look like they are leading to images are now
536 blocked as image instead of empty documents. Doing the latter causes
537 WebKit-based clients to show a "missing image" icon which may mess up
539 - The no-such-domain template is used for DNS resolution
540 problems with FEATURE_IPV6_SUPPORT enabled. Previously the
541 connect-failed template was used. Reported by 'zebul666'.
542 - Accepts quoted expiration dates even though RFC 2109 10.1.2
543 doesn't seem to allow them. Reported anonymously.
544 - Don't try to forget connections if connection sharing is disabled.
545 This wasn't a real problem but caused an unnecessary log message.
546 - The still undocumented --enable-extended-host-patterns configure
547 option has a better description.
548 - Fixed an error message that would claim a write to the server
549 failed when actually writing to the client failed.
550 - Log the crunch reason before trying to write to the client.
551 The log is easier to read that way.
552 - Several log messages about client connections also mention
554 - handle-as-empty-document no longer depends on the image blocking
556 - Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
557 - uagen, a Firefox User-Agent generator for Privoxy and Mozilla
558 browsers has been imported and is available in the tarball's
560 - The scripts in the tools directory treat unknown parameters
563 *** Version 3.0.15 Beta ***
565 - In case of missing server data, no error message is send to the
566 client if the request arrived on a reused connection. The client
567 is then supposed to silently retry the request without bothering
568 the user. This should significantly reduce the frequency of the
569 "No server or forwarder data received" error message many users
571 - More reliable detection of prematurely closed client sockets
572 with keep-alive enabled.
573 - FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
574 FEATURE_CONNECTION_SHARING and now available on
576 - Improved handling of POST requests on reused connections.
577 Should fix problems with stalled connections after submitting
578 form data with some browser configurations.
579 - Fixed various latency calculation issues.
580 - Allows the client to pass NTLM authentication requests to a
581 forwarding proxy. This was already assumed and hinted to work
582 in 3.0.13 beta but actually didn't. Now it's confirmed to work
583 with IE, Firefox and Chrome.
584 Thanks to Francois Botha and Wan-Teh Chang
585 - Fixed a calculation problem if receiving the server headers
586 takes more than two reads, that could cause Privoxy to terminate
587 the connection prematurely. Reported by Oliver.
588 - Compiles again on platforms such as OpenBSD and systems
589 using earlier glibc version that don't support AI_ADDRCONFIG.
590 Anonymously submitted in #2872591.
591 - A bunch of MS VC project files and Suse and Redhat RPM spec
592 files have been removed as they were no longer maintained for
594 - Overly long action lines are properly rejected with a proper
595 error message. Previously they would be either rejected as
596 invalid or cause a core dump through abort().
597 - Already timed-out connections are no longer temporarily remembered.
598 They weren't reused anyway, but wasted a socket slot.
599 - len refers to the number of bytes actually read which might
600 differ from the ones received. Adjust log messages accordingly.
601 - The optional JavaScript on the CGI page uses encodeURIComponent()
602 instead of escape() which doesn't encode all characters that matter.
603 Anonymously reported in #2832722.
604 - Fix gcc45 warnings in decompress_iob().
605 - Various log message improvements.
606 - Privoxy-Regression-Test supports redirect tests.
607 - Privoxy-Log-Parser can gather some connection statistics.
609 *** Version 3.0.14 Beta ***
611 - The latency is taken into account when evaluating whether or not to
612 reuse a connection. This should significantly reduce the number of
613 connections problems several users reported.
614 - If the server doesn't specify how long the connection stays alive,
615 Privoxy errs on the safe side of caution and assumes it's only a second.
616 - The error pages for connection timeouts or missing server data use a
617 Last-Modified date in the past. Retry attempts are detected and Privoxy
618 removes the If-Modified-Since header to prevent the server from responding
619 with status code 304 in which case the client would reuse the error message.
620 - Setting keep-alive-timeout to 0 disables keep-alive support. Previously
621 Privoxy would claim to allow persistence but not reuse the connection.
622 - Pipelined requests are less likely to be mistaken for the request
623 body of the previous request. Note that Privoxy still has no real
624 pipeline support and will either serialize pipelined requests or
625 drop them in which case the client has to resent them.
626 - Fixed a crash on some Windows versions when header randomization
627 is enabled and the date couldn't be parsed.
628 - Privoxy's keep-alive timeout for the current connection is reduced
629 to the one specified in the client's Keep-Alive header.
630 - For HTTP/1.1 requests, Privoxy implies keep-alive support by not
631 setting any Connection header instead of using 'Connection: keep-alive'.
632 - If the socket isn't reusable, Privoxy doesn't temporarily waste
633 a socket slot to remember the connection.
634 - If keep-alive support is disabled but compiled in, the client's
635 Keep-Alive header is removed.
636 - Fixed a bug on mingw32 where downloading large files failed if
637 keep-alive support was enabled.
638 - Fixed a bug that (at least theoretically) could cause log
639 timestamps to be occasionally off by about a second.
640 - No Proxy-Connection header if added if there already is one.
641 - The configure script respects the $PATH variable when searching
644 *** Version 3.0.13 Beta ***
646 - Added IPv6 support. Thanks to Petr Pisar who not only provided
647 the initial patch but also helped a lot with the integration.
648 - Added client-side keep-alive support.
649 - The connection sharing code is only used if the connection-sharing
651 - The max-client-connections option has been added to restrict
652 the number of client connections below a value enforced by
653 the operating system.
654 - Fixed a regression reintroduced in 3.0.12 that could cause
655 crashes on mingw32 if header date randomization was enabled.
656 - Compressed content with extra fields couldn't be decompressed
657 and would get passed to the client unfiltered. This problem
658 has only be detected through statical analysis with clang as
659 nobody seems to be using extra fields anyway.
660 - If the server resets the Connection after sending only the headers
661 Privoxy forwards what it got to the client. Previously Privoxy
662 would deliver an error message instead.
663 - Error messages in case of connection timeouts use the right
665 - If spawning a child to handle a request fails, the client
666 gets an error message and Privoxy continues to listen for
667 new requests right away.
668 - The error messages in case of server-connection timeouts or
669 prematurely closed server connections are now template-based.
670 - If zlib support isn't compiled in, Privoxy no longer tries to
671 filter compressed content unless explicitly asked to do so.
672 - In case of connections that are denied based on ACL directives,
673 the memory used for the client IP is no longer leaked.
674 - Fixed another small memory leak if the client request times out
675 while waiting for client headers other than the request line.
676 - The client socket is kept open until the server socket has
677 been marked as unused. This should increase the chances that
678 the still-open connection will be reused for the client's next
679 request to the same destination. Note that this only matters
680 if connection-sharing is enabled.
681 - A TODO list has been added to the source tarball to give potential
682 volunteers a better idea of what the current goals are. Donations
683 are still welcome too: http://www.privoxy.org/faq/general.html#DONATE
685 *** Version 3.0.12 ***
687 - The socket-timeout option now also works on platforms whose
688 select() implementation modifies the timeout structure.
689 Previously the timeout was triggered even if the connection
690 didn't stall. Reported by cyberpatrol.
691 - The Connection: keep-alive code properly deals with files
692 larger than 2GB. Previously the connection was closed too
694 - The content length for files above 2GB is logged correctly.
695 - The user-manual directive on the show-status page links to
696 the documentation location specified with the directive,
697 not to the Privoxy website.
698 - When running in daemon mode, Privoxy doesn't log anything
699 to the console unless there are errors before the logfile
701 - The show-status page prints warnings about invalid directives
702 on the same line as the directives themselves.
703 - Fixed several justified (but harmless) compiler warnings,
704 mostly on 64 bit platforms.
705 - The mingw32 version explicitly requests the default charset
706 to prevent display problems with some fonts available on more
707 recent Windows versions. Patch by Burberry.
708 - The mingw32 version uses the Privoxy icon in the alt-tab
709 windows. Patch by Burberry.
710 - The timestamp and the thread id is omitted in the "Fatal error"
711 message box on mingw32.
712 - Fixed two related mingw32-only buffer overflows. Triggering
713 them required control over the configuration file, therefore
714 this isn't seen as a security issue.
715 - In verbose mode, or if the new option --show-skipped-tests
716 is used, Privoxy-Regression-Test logs skipped tests and the
719 *** Version 3.0.11 ***
721 - On most platforms, outgoing connections can be kept alive and
722 reused if the server supports it. Whether or not this improves
723 things depends on the connection.
724 - When dropping privileges, membership in supplementary groups
725 is given up as well. Not doing that can lead to Privoxy running
726 with more rights than necessary and violates the principle of
727 least privilege. Users of the --user option are advised to update.
728 Thanks to Matthias Drochner for reporting the problem,
729 providing the initial patch and testing the final version.
730 - Passing invalid users or groups with the --user option
731 didn't lead to program exit. Regression introduced in 3.0.7.
732 - The match all section has been moved from default.action
733 to a new file called match-all.action. As a result the
734 default.action no longer needs to be touched by the user
735 and can be safely overwritten by updates.
736 - The standard.action file has been removed. Its content
737 is now part of the default.action file.
738 - In some situations the logged content length was slightly too low.
739 - Crunched requests are logged with their own log level.
740 If you used "debug 1" in the past, you'll probably want
741 to additionally enable "debug 1024", otherwise only passed
742 requests will be logged. If you only care about crunched
743 requests, simply replace "debug 1" with "debug 1024".
744 - The crunch reason has been moved to the beginning of the
745 crunch message. For HTTP URLs, the protocol is logged as well.
746 - Log messages are shortened by printing the thread id on its
747 own (as opposed to putting it inside the string "Privoxy()").
748 - The config option socket-timeout has been added to control
749 the time Privoxy waits for data to arrive on a socket.
750 - Support for remote toggling is controlled by the configure
751 option --disable-toggle only. In previous versions it also
752 depended on the action editor and thus configuring with the
753 --disable-editor option would disable remote toggling support
755 - Requests with invalid HTTP versions are rejected.
756 - The template symbol @date@ can be used to include a date(1)-like
757 time string. Initial patch submitted by Endre Szabo.
758 - Responses from shoutcast servers are accepted again.
759 Problem reported and fix suggested by Stefan.
760 - The hide-forwarded-for-headers action has been replaced with
761 the change-x-forwarded-for{} action which can also be used to
762 add X-Forwarded-For headers. The latter functionality already
763 existed in Privoxy versions prior to 3.0.7 but has been removed
764 as it was often used unintentionally (by not using the
765 hide-forwarded-for-headers action).
766 - A "clear log" view option was added to the mingw32 version
767 to clear out all of the lines in the Privoxy log window.
768 Based on a patch submitted by T Ford.
769 - The mingw32 version uses "critical sections" now, which prevents
770 log message corruption under load. As a side effect, the
771 "no thread-safe PRNG" warning could be removed as well.
772 - The mingw32 version's task bar icon is crossed out and
773 the color changed to gray if Privoxy is toggled off.
775 *** Version 3.0.10 ***
777 - Ordinary configuration file changes no longer cause program
778 termination on OS/2 if the name of the logfile hasn't been
779 changed as well. This regression probably crept in with the
780 logging improvements in 3.0.7. Reported by Maynard.
781 - The img-reorder filter is less likely to mess up JavaScript code in
782 img tags. Problem and solution reported by Glenn Washburn in #2014552.
783 - The source tar ball now includes Privoxy-Log-Parser,
784 a syntax-highlighter for Privoxy logs. For fancy screenshots see:
785 http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
786 Documentation is available through perldoc(1).
788 *** Version 3.0.9 Beta ***
790 - Added SOCKS5 support (with address resolution done by
791 the SOCKS5 server). Patch provided by Eric M. Hopper.
792 - The "blocked" CGI pages include a block reason that was
793 provided as argument to the last-applying block action.
794 - If enable-edit-actions is disabled (the default since 3.0.7 beta)
795 the show-status page hides the edit buttons and explains why.
796 Previously the user would get the "this feature has been disabled"
797 message after using the edit button.
798 - Forbidden CONNECT requests are treated like blocks by default.
799 The now-pointless treat-forbidden-connects-like-blocks action
801 - Not enabling limit-connect now allows CONNECT requests to all ports.
802 In previous versions it would only allow CONNECT requests to port 443.
803 Use +limit-connect{443} if you think you need the old default behaviour.
804 - The CGI editor gets turned off after three edit requests with invalid
805 file modification timestamps. This makes life harder for attackers
806 who can leverage browser bugs to send fake Referers and intend to
807 brute-force edit URLs.
808 - Action settings for multiple patterns in the same section are
809 shared in memory. As a result these sections take up less space
810 (and are loaded slightly faster). Problem reported by Franz Schwartau.
811 - Linear white space in HTTP headers will be normalized to single
812 spaces before parsing the header's content, headers split across
813 multiple lines get merged first. This should prevent problems like:
814 * letting the session-cookies-only action slip
815 some Cookies through unmodified,
816 * only suppressing the first line of a header,
817 thus creating an invalid one, and
818 * to incorrectly block headers with valid timestamps
819 that weren't properly recognized.
820 Headers that could trigger these problems are unlikely to appear
821 in "normal" web traffic, but could be intentionally generated to
822 fool some of Privoxy's header parsers.
823 - Host information is gathered outside the main thread so it's less
824 likely to delay other incoming connections if the host is misconfigured.
825 - New config option "hostname" to use a hostname other than
826 the one returned by the operating system. Useful to speed-up responses
827 for CGI requests on misconfigured systems. Requested by Max Khon.
828 - The CGI editor supports the "disable all filters of this type"
829 directives "-client-header-filter", "-server-header-filter",
830 "-client-header-tagger" and "-server-header-tagger".
831 - Fixed false-positives with the link-by-url filter and URLs that
832 contain the pattern "/jump/".
833 - The less-download-windows filter no longer messes
834 "Content-Type: application/x-shockwave-flash" headers up.
835 - In the show-url-info page's "Final results" section active and
836 inactive actions are listed separately. Patch provided by Lee.
837 - The GNUmakefile supports the DESTDIR variable. Patch for
838 the install target submitted by Radoslaw Zielinski.
839 - Embedding the content of configuration files in the show-status
840 page is significantly faster now. For a largish action file (1 MB)
841 a speedup of about 2450 times has been measured. This is mostly
842 interesting if you are using large action files or regularly use
843 Privoxy-Regression-Test while running Privoxy through Valgrind,
844 for stock configuration files it doesn't really matter.
845 - If zlib support is unavailable and there are content
846 filters active but the prevent-compression action is disabled,
847 the show-url-info page includes a warning that compression
848 might prevent filtering.
849 - The show-url-info page provides an OpenSearch Description that
850 allows to access the page through browser search plugins.
851 - Custom client-header filters that rewrite the request line
852 incorrectly no longer cause Privoxy to crash. Reported by din_a4.
853 - The obsolete kill-popups action has been removed as the
854 PCRS-based popup filters can do the same and are slightly
856 - The inspect-jpegs action has been removed.
857 - The send-wafer and send-vanilla-wafer actions have been removed.
858 They weren't particular useful and their behaviour could be emulated
859 with add-header anyway.
860 - Privoxy-Regression-Test has been significantly improved.
861 - Most sections in the default.action file contain tests for
862 Privoxy-Regression-Test to verify that they are working as intended.
863 - Parts of Privoxy have been refactored to increase maintainability.
864 - Building with zlib (if available) is done by default.
866 *** Version 3.0.8 ***
868 - Fixed a small memory leak when listen-address only specifies the port.
869 - The source tar balls now include Privoxy-Regression-Test which
870 (upon other things) can be used to automatically detect some
871 packaging problems. Packagers are welcome to give it a try.
872 - Reverted a change in 3.0.7 that caused path patterns to be checked
873 even if the host pattern match already failed. While this doesn't
874 noticeable affect the performance, it makes it less likely to run
875 out of stack space with overly-complex path patterns the user might
877 - Updated the msn, yahoo and google filters to work as advertised again.
878 - The warning message shown by the show-status CGI page is easier to
879 understand. Previously it wasn't clear that the error message
880 is shown below the invalid directive. (Reported by Lee)
881 - When regenerating Content-Disposition headers the more common
882 spelling is used for the name. Previously it was written without caps.
883 - Less confusing log message if the content type isn't overwritten
884 because force-text-type wasn't used but the old type doesn't look
885 like content that would be filtered normally.
886 - Better log messages if the user tries to execute filters that
888 - Treat the non-standard Request-Range headers like standard range
889 headers and suppress them if content filtering is enabled.
890 - Prevent the log messages for CONNECT requests to unacceptable
891 ports from printing the limit-connect argument as [null] if
892 limit-connect hasn't been explicitly enabled.
893 - Don't disable the mingw32 log window if the logfile directive
894 isn't used. While it was an intentional change in 3.0.7 at least
895 one user perceived it as a regression and the same effect can
896 be achieved by disabling all debug directives.
897 - Fixed two minor problems related to the win32 build process: a css
898 file was not being in the installer and the trustfile comment in the
899 config.txt referenced a nonexisting file
900 - Minor documentation fixes.
902 *** Version 3.0.7 Beta ***
904 - Added zlib support to filter content with gzip and deflate
905 encoding. (Patch provided by Wil Mahan)
906 - Dedicated filters and actions are used for header filtering.
907 "filter-client-headers" and "filter-client-headers" are no longer
908 supported, use server-header-filter{} and client-header-filter{}
910 - Tags can be used to change actions based on HTTP headers.
911 - New server-header filter: less-download-windows.
912 - New client-header taggers: css-requests, image-requests,
913 client-ip-address, http-method, allow-post, complete-url,
914 user-agent and privoxy-control.
915 - New server-header taggers: content-type and privoxy-control.
916 - The forward-override{} action allows to change the forwarding
917 settings through the action files, for example based on client
918 headers like the User-Agent, or the request origin.
919 - Socks errors are no longer handled by the CGI page for
920 DNS resolution failures.
921 - CGI pages use favicons to signal whether they are error
922 or control pages. This is useful if you rely heavily on
924 - The show-url-info CGI page shows the forwarding settings.
925 - "Crunch!" log messages (used when Privoxy answers requests
926 by itself) now also contain the reason.
927 - Allow to rewrite the request destination behind the client's back.
928 - Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
929 - Fixes possible deadlocks and crashes on OpenBSD.
930 Patch provided by Ralf Horstmann.
931 - The CGI action editor allows to edit actionfiles with previously
932 forbidden characters like dots.
933 - New trust entries are saved with a comment that contains the
934 trusted referring URL (Suggested by Daniel Griscom).
935 - Filter descriptions are HTML encoded automatically.
936 - New config option "split-large-forms" to work
937 around a browser bug that caused IE6 and IE7 to ignore
938 the Submit button on the edit-actions-for-url CGI page.
939 - New config option "allow-cgi-request-crunching" to allow
940 requests for Privoxy's CGI pages to be blocked, redirected
941 or (un)trusted like ordinary requests.
942 - Empty filter files no longer interrupt the filtering process
943 prematurely and are correctly listed on the show-status CGI page.
944 - New config option "accept-intercepted-requests" to combine
945 Privoxy with any packet filter to build an intercepting proxy
946 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
947 - fast-redirects{} catch redirects to https URLs as well.
948 - redirect{s@foo@bar@} can be used to redirect to a rewritten
949 version of the original URL.
950 - Trap unsupported gopher proxy requests.
951 - Fixed a bug in the User Manual delivery on Windows
952 (mingw32 only). Images now show up correctly and HTML
953 pages are no longer padded with garbage data.
954 - Fixed several minor memory leaks, most of them discovered with Valgrind.
955 - Only unlink the pidfile if it's actually used.
956 - Retries after connection problems with forced requests
957 aren't blocked again.
958 - On Unix SIGABRT causes a core dump as expected and is no
959 longer treated as normal shutdown signal.
960 - The "access denied" CGI page is more descriptive and
961 allows retries to circumvent the referrer check.
962 - Updated PCRS to handle unexpected PCRE errors properly.
963 Fixed crashes that could occur if Privoxy was build
964 with external PCRE versions newer than Privoxy's internal
965 one. (Reported by Chung-chieh Shan)
966 - Fixed crashes with null bytes in PCRS replacement strings
967 (Patch provided by Felix Gröbert).
968 - Fixed crashes with header time randomization on mingw32.
969 - The CGI style sheet is no longer delivered if the referring
970 page isn't a Privoxy CGI page. This prevents a JavaScript-based
971 Privoxy detection "attack". Note that detecting Privoxy is
972 still possible through other ways and Privoxy was never intended
973 to be invisible anyway.
974 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
975 - The show-url-info CGI page displays a warning if Privoxy
976 is currently toggled off.
977 - The show-status CGI page suppresses the edit button
978 for action files if Privoxy has no write access.
979 - Most CGI error pages react properly to HEAD requests.
980 - Requests with RFC 3253 HTTP methods (used by Subversion)
981 are accepted. (Patch provided by Petr Kadlec)
982 - New config option "templdir" to change the location
983 of the CGI templates to make sure customized templates
985 - Better handling of "HTTP/1.1 100 Continue" responses.
986 - The background of the PNG pattern is transparent.
987 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
988 - Fixed crashes and possible action file corruptions
989 when lines containing hashes are written through the CGI editor.
990 - Supports dynamic filters which can contain variables.
991 - Supports tags to change the actions based on client or server headers.
992 - Incorrect actions are logged before program termination.
993 - The "actionsfile" syntax in the configuration file is consistent
994 with the rest of the configuration options and requires the
995 whole file name. This is an incompatible change, if you use
996 an old configuration file you might have to append ".action"
997 to your "actionsfile" directives.
998 - With the configuration file option "enforce-blocks" the
999 "go there anyway" mechanism can be disabled without recompiling
1001 - More precise error messages in case of incorrect acl syntax.
1002 - Logs a warning if filtering is enabled but impossible due
1003 to lack of zlib support or use of the prevent-compression action.
1004 - Less noisy handling of Cookie:" and "Connection:" headers.
1005 - Improved error messages in case of connection problems.
1006 - Fix a command-line-parsing bug that was introduced before 3.0.5
1007 beta and caused Privoxy to treat the last argument as configuration
1008 file if no configuration file was specified.
1009 - Treat unknown command line options as fatal errors instead
1010 of silently ignoring them.
1011 - Use string functions with length checks more often.
1012 - Don't log CONNECT requests twice.
1013 - Allow to log the source address for ACL-related connection drops.
1014 - Don't ignore applying filters if the server didn't
1015 specify a Content-Type. Bug reported by Amuro Namie.
1016 - Rejected CONNECT requests are logged with log level info
1017 (enabled by default) and the reason for the block.
1018 - New command line option "--pre-chroot-nslookup hostname" to
1019 intialize the resolver library before chroot'ing. On some systems this
1020 reduces the number of files that must be copied into the chroot tree.
1021 (Patch provided by Stephen Gildea)
1022 - Fix a long-standing memory corruption bug that could cause
1023 Privoxy to overwrite a single byte in memory it didn't explicitly
1024 allocate (but that probably was allocated anyway due to bucket size).
1025 - Send template-based CGI pages as HTTP/1.1 unless the client
1027 - Let the first line in connection established responses
1028 end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
1029 - If no log file has been specified, disable logging instead of logging
1031 - Don't block stderr when in daemon mode.
1032 - Ignore missing zero-chunks when filtering chunk-encoded content.
1033 Earlier Privoxy versions would buffer and then forward the content
1034 unmodified which caused some browsers to simply show empty pages.
1035 - Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
1036 - The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
1037 action isn't being used has been removed.
1038 - Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
1040 - Minor code clean-ups, filter and action file updates.
1041 (Some of them reported by Davide Alberani, Markus Elfring,
1042 Stefan Huehner and Adam Piggott)
1044 *** Version 3.0.6 ***
1046 - New content filters: no-ping, google, msn, yahoo and blogspot.
1047 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
1048 and hide-tor-exit-notation.
1049 - The special header "X-Filter: No" now disables header filtering as well.
1050 - Improved the filters img-reorder, js-annoyances, webbugs,
1051 banners-by-size, banners-by-link and ie-exploits to make them
1052 less likely to break anything.
1053 - Removed outdated URL patterns in default.action and added new ones.
1054 - Added redirection from http://p.p/user-manual to http://p.p/user-manual/
1055 - Changed webinterface default values for hide-user-agent, hide-referrer
1056 and set-image-blocker.
1058 *** Version 3.0.5 Beta ***
1060 - Windows version can be installed/started as a service.
1061 - Windows icon stays blue when Privoxy is idle, green when busy.
1062 - Integrated Fabian Keil's extensive patch. See:
1063 http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
1064 following new or significantly improved actions (among many
1065 other improvements):
1067 content-type-overwrite{}
1068 crunch-client-header{string}
1069 crunch-if-none-match
1070 crunch-server-header{string}
1071 fast-redirects{check-decoded-url}
1072 filter-client-headers
1073 filter-server-headers
1075 handle-as-empty-document
1076 hide-accept-language{}
1077 hide-content-disposition{}
1078 hide-if-modified-since
1079 hide-referrer{conditional-block}
1080 overwrite-last-modified{}
1082 treat-forbidden-connects-like-blocks

1085 copies of Privoxy's error messages after the cause of the problem
1087 - Improved DNS error handling.

1089 - Added jpeg filtering to defend against MS jpeg vulnerability MS04-028
1090 with the new inspect-jpegs action.
1091 - Removed the "arbitrary" 1000 filter limit - addresses tracker #911950

1105 *** Version 3.0.3 ***
1107 - Fixed yet another two memory leaks. Process growth seems stopped now.
1108 - Further tightened security against malicious toggle-off links.
1109 - Excluded text/plain MIME types from filtering. This fixes a
1110 couple of client-crashing, download corruption and
1111 Privoxy performance issues, whose root cause lies in
1112 web servers labelling content of unknown type as text/plain.
1113 - Assorted fixes for POSIX compliance, signal handling, graceful
1114 termination, compiler warnings, OSX support, Win32 systray,
1115 error logging, hostname wildcards, correct detection of NetBSD.
1116 - Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs
1117 including the notorious "blank page" problem.

1130 - Refined the default action file through >400 items of user feedback
1132 - Assorted refinements, optimizations and fixes in the js-annoyances,
1133 img-reorder, banners-by-size, banners-by-link, webbugs, refresh-tags,
1134 html-annoyances, content-cookies and fun filters
1135 - Replaced filter "popups" by choice between two modes:
1136 - "unsolicited-popups" tries to catch only the unsolicited ones
1137 - "all-popups" tries to kill them all (as before)
1138 - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
1139 - New filter "jumping-windows" that prevents windows from resizing
1140 and moving themselves
1141 - New filter "demoronizer" which fixes MS's abuse of std charsets
1142 (common cases anyway).
1143 - Replaced "nimda" with more general "ie-exploits" filter in which
1144 all filters for exploits shall be collected
1145 - Improved cookie logging
1146 - Rewrote make install target. Added uninstall and install-strip
1148 - Fixed a potential (application-level, NOT OS-level!) security
1149 problem involving remote toggling and action file manipulation
1150 by mailicious websites.
1151 - Added ability to chroot (thanks to Sviatoslav Sviridov)
1152 - Added more action aliases for prehistoric action names

1169 - Three filters fixed (again!)
1170 - Assorted small fixes and doc enhancements
1172 *** Version 2.9.16 ***
1174 - Major revamp of default.action to get rid of years of cruft.
1175 - Same for default.filter

1200 - Various other minor fixes.
1202 *** Version 2.9.13 Beta ***
1204 - *NEWS*: The project has been renamed to Privoxy! The new name is
1205 reflected throughout (file locations, etc).
1206 - ijb.action is now default.action. re_filterfile is now
1208 - http://i.j.b/ is now http://p.p/

1236 - Fix restart failure where sockets were in TIME_WAIT.
1237 - Fixes for actions cgi editor, make sure we have right file.
1238 - A --pidfile command line option now, in addition to --help,
1239 --version, --no-daemon, --user and configfile. --no-daemon replaces
1240 the former -d option and _DEBUG define. --user will drop privileges
1241 to the specified user.
1242 - Signal handling cleanups (*nix).
1243 - CGI actions editor improvements and fixes.

1276 - Many other minor bugfixes
1277 - Start a ChangeLog :)
1281 *** Version 2.9.3 pre-Alpha Changes ***
1283 - Amiga support (completely untested by me - I don't have an Amiga)
1284 - "tinygif 3" support (redirects blocked images to a specified URL, so
1285 the browser doesn't have to load and cache many copies of the same
1287 - one case where there were both local and global "referrer" variables
1288 (yuck!) clarified by renaming the local one to "refer".
1289 - Fixed some places where close() was used instead of close_socket().
1290 Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
1291 - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
1292 FORCE_LOAD_PREFIX. Needs fixing properly.
1293 - Most URLs hardcoded into Junkbuster were changed to go through a script
1294 e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
1295 The only other URLs left are the GNU GPL:
1296 http://www.fsf.org/copyleft/gpl.html
1298 http://ijbswa.sourceforge.net/
1299 ... and various URLs which will be intercepted by Junkbuster anyway.
1300 TODO: Still need to do something with the URLs in Junkbuster Corp's
1301 copyright/trademark notice on the bottom of the show-proxy-args page.
1302 - PCRE or GNU Regex is now a #define option.
1305 *** Version 2.9.2 pre-Alpha Changes ***
1307 - Andreas applied the latest version of the FORCE patch.
1310 *** Version 2.9.1 pre-Alpha Changes ***
1312 - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
1313 (BTW: I think FORCE is precise enough, since loading remote
1314 data is the whole purpose of a proxy..)
1315 - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
1316 is more elegant and looks like a hostname in the URL, it doesn't
1317 make clear to the inexperienced user that the proxy is bypassed. It
1318 also has a higher name collision risk.
1319 - Filled in the function header templates for my functions in
1320 parsers.c (again). They obviously got lost in our current
1322 - Cut the credit for the §-referrer-option from the config file,
1323 that Stefan had placed there.
1324 - Improved the re_filterfile
1327 *** Version 2.9.0 pre-Alpha Changes ***
1329 - Now use PCRE, not GNU REGEX. I have not yet had chance to check the
1330 syntax of the block/image/cookie file to ensure that they match what
1331 is expected - however they seem to work.
1332 - Replaced "configure" script with one generated by "autoconf". Also
1333 use a header "config.h" (was ijbconfig.h in my previous release) for
1334 the #defines. "config.h" is now generated with "autoheader" from
1335 "acconfig.h" and "configure.in". (Note that to install you do not
1336 need autoconf or autoheader - just run "./configure".)
1337 To see command-line options, run "./configure --help".
1338 This is my first ever autoconf script, so it has some rough edges
1339 (how PCRE is handled is the roughest).
1340 - Error logging code replaced with new module errlog.c, based on the
1341 one from JunkbusterMT (but with the threading code removed).
1342 - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
1343 apply all of these, since I had already independently done conditional
1344 popup file, conditional image file, and integration of popup code.
1345 - ACL, Jar and trust files conditionally compiled.
1346 - New source file headers.
1347 - Various cosmetic changes. (But I have not consistently ordered the
1348 config files - I think that's worthwhile, but it's 1am and I want to
1350 - RCS tags on .h files.
1351 - RCS tags are const char[] rather than const char *. (Saves 4 bytes
1353 - VC++ project files renamed to vc_junkbuster.*.
1354 - show-proxy-args now shows status of all conditionals, not just REGEX
1355 - Various functions moved around. Most notably all the system-specific
1356 sockets code which was spread between jcc.c, bind.c, and connect.c,
1357 has been moved to "jbsockets.c". The non-system-specific code from
1358 connect.c and socks4.c has been movet to "gateway.c". Also, the
1359 config file loader and the global variables it writes to have been
1360 moved to "loadcfg.c". (Maybe this should go into loaders.c?)
1361 And candidate for the "worst filename ever" award is "miscutil.c",
1362 which contains, well, miscellaneous utility functions like zalloc.
1363 (Suggestions for a better name for this file are welcome!)
1364 - Loaders now use a common function to read a line and skip comments,
1365 and this function also stores the proxy_args.
1366 - Added ./junkbuster --help (Not for Win32 GUI)
1367 - Added ./junkbuster --version (Not for Win32 GUI)
1368 - Win32 resources are now all marked as "U.S. English", rather than
1369 being a mix of "U.S. English", "U.K. English" and "Irish English".
1370 - Version number changes to 2.9.0
