3 --------------------------------------------------------------------
6 - Added SOCKS5 support. Patch provided by Eric M. Hopper.
7 - The "blocked" CGI pages include a block reason that was
8 provided as argument to the last-applying block action.
9 - If enable-edit-actions is disabled (the default since 3.0.7 beta)
10 the show-status page hides the edit buttons and explains why.
11 Previously the user would get the "this feature has been disabled"
12 message after using the edit button.
13 - Forbidden CONNECT requests are treated like blocks by default.
14 The now-pointless treat-forbidden-connects-like-blocks action
16 - Not enabling limit-connect now allows CONNECT requests to all ports.
17 In previous versions it would only allow CONNECT requests to port 443.
18 Use +limit-connect{443} if you think you need the old default behaviour.
19 - The CGI editor gets turned off after three edit requests with invalid
20 file modification timestamps. This makes life harder for attackers
21 who can leverage browser bugs to send fake Referers and intend to
22 brute-force edit URLs.
23 - Host information is gathered outside the main thread so it's less
24 likely to delay other incoming connections if the host is misconfigured.
25 - The CGI editor supports the "disable all filters of this type"
26 directives "-client-header-filter", "-server-header-filter",
27 "-client-header-tagger" and "-server-header-tagger".
28 - Fixed false-positives with the link-by-url filter and URLs that
29 contain the pattern "/jump/".
30 - The less-download-windows filter no longer messes
31 "Content-Type: application/x-shockwave-flash" headers up.
32 - In the show-url-info page's "Final results" section active and
33 inactive actions are listed separately. Patch provided by Lee.
37 - Fixed a small memory leak when listen-address only specifies the port.
38 - The source tar balls now include Privoxy-Regression-Test which
39 (upon other things) can be used to automatically detect some
40 packaging problems. Packagers are welcome to give it a try.
41 - Reverted a change in 3.0.7 that caused path patterns to be checked
42 even if the host pattern match already failed. While this doesn't
43 noticeable affect the performance, it makes it less likely to run
44 out of stack space with overly-complex path patterns the user might
46 - Updated the msn, yahoo and google filters to work as advertised again.
47 - The warning message shown by the show-status CGI page is easier to
48 understand. Previously it wasn't clear that the error message
49 is shown below the invalid directive. (Reported by Lee)
50 - When regenerating Content-Disposition headers the more common
51 spelling is used for the name. Previously it was written without caps.
52 - Less confusing log message if the content type isn't overwritten
53 because force-text-type wasn't used but the old type doesn't look
54 like content that would be filtered normally.
55 - Better log messages if the user tries to execute filters that
57 - Treat the non-standard Request-Range headers like standard range
58 headers and suppress them if content filtering is enabled.
59 - Prevent the log messages for CONNECT requests to unacceptable
60 ports from printing the limit-connect argument as [null] if
61 limit-connect hasn't been explicitly enabled.
62 - Don't disable the mingw32 log window if the logfile directive
63 isn't used. While it was an intentional change in 3.0.7 at least
64 one user perceived it as a regression and the same effect can
65 be achieved by disabling all debug directives.
66 - Fixed two minor problems related to the win32 build process: a css
67 file was not being in the installer and the trustfile comment in the
68 config.txt referenced a nonexisting file
69 - Minor documentation fixes.
71 *** Version 3.0.7 Beta ***
73 - Added zlib support to filter content with gzip and deflate
74 encoding. (Patch provided by Wil Mahan)
75 - Dedicated filters and actions are used for header filtering.
76 "filter-client-headers" and "filter-client-headers" are no longer
77 supported, use server-header-filter{} and client-header-filter{}
79 - Tags can be used to change actions based on HTTP headers.
80 - New server-header filter: less-download-windows.
81 - New client-header taggers: css-requests, image-requests,
82 client-ip-address, http-method, allow-post, complete-url,
83 user-agent and privoxy-control.
84 - New server-header taggers: content-type and privoxy-control.
85 - The forward-override{} action allows to change the forwarding
86 settings through the action files, for example based on client
87 headers like the User-Agent, or the request origin.
88 - Socks errors are no longer handled by the CGI page for
89 DNS resolution failures.
90 - CGI pages use favicons to signal whether they are error
91 or control pages. This is useful if you rely heavily on
93 - The show-url-info CGI page shows the forwarding settings.
94 - "Crunch!" log messages (used when Privoxy answers requests
95 by itself) now also contain the reason.
96 - Allow to rewrite the request destination behind the client's back.
97 - Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
98 - Fixes possible deadlocks and crashes on OpenBSD.
99 Patch provided by Ralf Horstmann.
100 - The CGI action editor allows to edit actionfiles with previously
101 forbidden characters like dots.
102 - New trust entries are saved with a comment that contains the
103 trusted referring URL (Suggested by Daniel Griscom).
104 - Filter descriptions are HTML encoded automatically.
105 - New config option "split-large-forms" to work
106 around a browser bug that caused IE6 and IE7 to ignore
107 the Submit button on the edit-actions-for-url CGI page.
108 - New config option "allow-cgi-request-crunching" to allow
109 requests for Privoxy's CGI pages to be blocked, redirected
110 or (un)trusted like ordinary requests.
111 - Empty filter files no longer interrupt the filtering process
112 prematurely and are correctly listed on the show-status CGI page.
113 - New config option "accept-intercepted-requests" to combine
114 Privoxy with any packet filter to build an intercepting proxy
115 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
116 - fast-redirects{} catch redirects to https URLs as well.
117 - redirect{s@foo@bar@} can be used to redirect to a rewritten
118 version of the original URL.
119 - Trap unsupported gopher proxy requests.
120 - Fixed a bug in the User Manual delivery on Windows
121 (mingw32 only). Images now show up correctly and HTML
122 pages are no longer padded with garbage data.
123 - Fixed several minor memory leaks, most of them discovered with Valgrind.
124 - Only unlink the pidfile if it's actually used.
125 - Retries after connection problems with forced requests
126 aren't blocked again.
127 - On Unix SIGABRT causes a core dump as expected and is no
128 longer treated as normal shutdown signal.
129 - The "access denied" CGI page is more descriptive and
130 allows retries to circumvent the referrer check.
131 - Updated PCRS to handle unexpected PCRE errors properly.
132 Fixed crashes that could occur if Privoxy was build
133 with external PCRE versions newer than Privoxy's internal
134 one. (Reported by Chung-chieh Shan)
135 - Fixed crashes with null bytes in PCRS replacement strings
136 (Patch provided by Felix Gröbert).
137 - Fixed crashes with header time randomization on mingw32.
138 - The CGI style sheet is no longer delivered if the referring
139 page isn't a Privoxy CGI page. This prevents a JavaScript-based
140 Privoxy detection "attack". Note that detecting Privoxy is
141 still possible through other ways and Privoxy was never intended
142 to be invisible anyway.
143 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
144 - The show-url-info CGI page displays a warning if Privoxy
145 is currently toggled off.
146 - The show-status CGI page suppresses the edit button
147 for action files if Privoxy has no write access.
148 - Most CGI error pages react properly to HEAD requests.
149 - Requests with RFC 3253 HTTP methods (used by Subversion)
150 are accepted. (Patch provided by Petr Kadlec)
151 - New config option "templdir" to change the location
152 of the CGI templates to make sure customized templates
154 - Better handling of "HTTP/1.1 100 Continue" responses.
155 - The background of the PNG pattern is transparent.
156 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
157 - Fixed crashes and possible action file corruptions
158 when lines containing hashes are written through the CGI editor.
159 - Supports dynamic filters which can contain variables.
160 - Supports tags to change the actions based on client or server headers.
161 - Incorrect actions are logged before program termination.
162 - The "actionsfile" syntax in the configuration file is consistent
163 with the rest of the configuration options and requires the
164 whole file name. This is an incompatible change, if you use
165 an old configuration file you might have to append ".action"
166 to your "actionsfile" directives.
167 - With the configuration file option "enforce-blocks" the
168 "go there anyway" mechanism can be disabled without recompiling
170 - More precise error messages in case of incorrect acl syntax.
171 - Logs a warning if filtering is enabled but impossible due
172 to lack of zlib support or use of the prevent-compression action.
173 - Less noisy handling of Cookie:" and "Connection:" headers.
174 - Improved error messages in case of connection problems.
175 - Fix a command-line-parsing bug that was introduced before 3.0.5
176 beta and caused Privoxy to treat the last argument as configuration
177 file if no configuration file was specified.
178 - Treat unknown command line options as fatal errors instead
179 of silently ignoring them.
180 - Use string functions with length checks more often.
181 - Don't log CONNECT requests twice.
182 - Allow to log the source address for ACL-related connection drops.
183 - Don't ignore applying filters if the server didn't
184 specify a Content-Type. Bug reported by Amuro Namie.
185 - Rejected CONNECT requests are logged with log level info
186 (enabled by default) and the reason for the block.
187 - New command line option "--pre-chroot-nslookup hostname" to
188 intialize the resolver library before chroot'ing. On some systems this
189 reduces the number of files that must be copied into the chroot tree.
190 (Patch provided by Stephen Gildea)
191 - Fix a long-standing memory corruption bug that could cause
192 Privoxy to overwrite a single byte in memory it didn't explicitly
193 allocate (but that probably was allocated anyway due to bucket size).
194 - Send template-based CGI pages as HTTP/1.1 unless the client
196 - Let the first line in connection established responses
197 end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
198 - If no log file has been specified, disable logging instead of logging
200 - Don't block stderr when in daemon mode.
201 - Ignore missing zero-chunks when filtering chunk-encoded content.
202 Earlier Privoxy versions would buffer and then forward the content
203 unmodified which caused some browsers to simply show empty pages.
204 - Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
205 - The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
206 action isn't being used has been removed.
207 - Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
209 - Minor code clean-ups, filter and action file updates.
210 (Some of them reported by Davide Alberani, Markus Elfring,
211 Stefan Huehner and Adam Piggott)
213 *** Version 3.0.6 ***
215 - New content filters: no-ping, google, msn, yahoo and blogspot.
216 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
217 and hide-tor-exit-notation.
218 - The special header "X-Filter: No" now disables header filtering as well.
219 - Improved the filters img-reorder, js-annoyances, webbugs,
220 banners-by-size, banners-by-link and ie-exploits to make them
221 less likely to break anything.
222 - Removed outdated URL patterns in default.action and added new ones.
223 - Added redirection from http://p.p/user-manual to http://p.p/user-manual/
224 - Changed webinterface default values for hide-user-agent, hide-referrer
225 and set-image-blocker.

229 - Windows version can be installed/started as a service.
230 - Windows icon stays blue when Privoxy is idle, green when busy.
231 - Integrated Fabian Keil's extensive patch. See:
232 http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
233 following new or significantly improved actions (among many
236 content-type-overwrite{}
237 crunch-client-header{string}
239 crunch-server-header{string}
240 fast-redirects{check-decoded-url}
241 filter-client-headers
242 filter-server-headers
244 handle-as-empty-document
245 hide-accept-language{}
246 hide-content-disposition{}
247 hide-if-modified-since
248 hide-referrer{conditional-block}
249 overwrite-last-modified{}
251 treat-forbidden-connects-like-blocks
253 - Standard-compliant clients are prevented from displaying cached
254 copies of Privoxy's error messages after the cause of the problem
256 - Improved DNS error handling.
257 - Multiple filter files can now be specified in config.
258 - Added jpeg filtering to defend against MS jpeg vulnerability MS04-028

261 - Thanks to Jindrich Makovicka for a race condition fix for the log
262 file. The race condition remains for non-pthread implementations.
263 Reference patch #1175720. Various other logging enhancements.
264 - A pile of assorted bug fixes, memory leaks, enhancements, etc.
265 - Moved Actions file reporting mechanism to SF tracker.

271 - Increase the compiled in limit of trusted referrers from 64 to 512
272 (for trustfile users).
274 *** Version 3.0.3 ***
276 - Fixed yet another two memory leaks. Process growth seems stopped now.
277 - Further tightened security against malicious toggle-off links.
278 - Excluded text/plain MIME types from filtering. This fixes a
279 couple of client-crashing, download corruption and
280 Privoxy performance issues, whose root cause lies in
281 web servers labelling content of unknown type as text/plain.
282 - Assorted fixes for POSIX compliance, signal handling, graceful
283 termination, compiler warnings, OSX support, Win32 systray,
284 error logging, hostname wildcards, correct detection of NetBSD.
285 - Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs
286 including the notorious "blank page" problem.
287 - Various filter improvements; most notably the unsolicited-popups
288 filter became less destructive

293 - Fixed two memory leaks, one serious
294 - Fixed bug in pcrs which could cause crashes with user-defined filters
295 - Fixed bug in domain name matching
296 - Assorted small fixes (Win32 menu, CGI URL editor, ..)
297 - Added basic support for the OPTIONS and TRACE http methods
298 - Added workaround for Bug in Mac OSX that made Privoxy crash occasionally
299 - Refined the default action file through >400 items of user feedback
301 - Assorted refinements, optimizations and fixes in the js-annoyances,
302 img-reorder, banners-by-size, banners-by-link, webbugs, refresh-tags,
303 html-annoyances, content-cookies and fun filters
304 - Replaced filter "popups" by choice between two modes:
305 - "unsolicited-popups" tries to catch only the unsolicited ones
306 - "all-popups" tries to kill them all (as before)
307 - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
308 - New filter "jumping-windows" that prevents windows from resizing
309 and moving themselves
310 - New filter "demoronizer" which fixes MS's abuse of std charsets
311 (common cases anyway).
312 - Replaced "nimda" with more general "ie-exploits" filter in which
313 all filters for exploits shall be collected
314 - Improved cookie logging
315 - Rewrote make install target. Added uninstall and install-strip
317 - Fixed a potential (application-level, NOT OS-level!) security
318 problem involving remote toggling and action file manipulation
319 by mailicious websites.
320 - Added ability to chroot (thanks to Sviatoslav Sviridov)
321 - Added more action aliases for prehistoric action names
322 - Add Slackware support to Makefile.
326 - Fixed Windows startmenu items, log window and tray icon menus.
327 - Added warning for bogus install target
328 - Added quicktime-kioskmode filter and improved frameset-borders
329 - Updated default.action based on latest feedback
330 - New PDF doc build process
331 - Add a user contrib module to cvs:
332 http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/ijbswa/contrib/
334 *** Version 2.9.18 ***
336 - Added workaround for IE bug that broke CGI interface
337 - Bugfix: String actions now reliably editable through CGI interface
338 - Three filters fixed (again!)
339 - Assorted small fixes and doc enhancements
341 *** Version 2.9.16 ***
343 - Major revamp of default.action to get rid of years of cruft.
344 - Same for default.filter
345 - Re-design and major improvements to the CGI editor interface.
346 - Address spurious 'out of memory' error due to incorrect file permissions.

353 - Actions files are changed to: default.action, standard.action, and
354 user.action. user.action is for personal/local configuration.
355 - The usual many small and miscellaneous bug and security fixes.
357 *** Version 2.9.14 Beta ***

362 - 'blocked-compact' template is removed. Various CGI improvements,
363 including an adaptive 'blocked' template.
364 - Various tweaks for actions file to get ready for stable 3.0
365 - Included a 'Bookmarklet' and PHP scripts for reporting actions file
366 problems via web interface at privoxy.org. Accessed via internal CGIs.
367 - Include cgi-style.css for templates.
368 - #include mechansim for common text in templates
369 - Various other minor fixes.

410 to the specified user.
411 - Signal handling cleanups (*nix).
412 - CGI actions editor improvements and fixes.
413 - Error handling improvements, especially out of memory.
414 - Default re_filterfile fix that caused spurious IJB logos

417 - Various other minor fixes.
420 *** Version 2.9.11 Beta Changes ***
422 - Add "session" cookie concept where cookies exist for the life
423 of that browser session only (ie never goes to disk).
424 - Checks for correct header length.
425 - Fix user:pass@host.domain.com auth bug.
426 - Better signal handling on *nix.
427 - Fix CFLAGS hard-coded in configure.in
428 - Fix threading bug re: gethostbyname() that caused random
429 URLs to fail in some cases.

444 - make should now abort if gmake (GNU make) not present.
445 - Many other minor bugfixes
446 - Start a ChangeLog :)
450 *** Version 2.9.3 pre-Alpha Changes ***
452 - Amiga support (completely untested by me - I don't have an Amiga)
453 - "tinygif 3" support (redirects blocked images to a specified URL, so
454 the browser doesn't have to load and cache many copies of the same
456 - one case where there were both local and global "referrer" variables
457 (yuck!) clarified by renaming the local one to "refer".
458 - Fixed some places where close() was used instead of close_socket().
459 Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
460 - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
461 FORCE_LOAD_PREFIX. Needs fixing properly.
462 - Most URLs hardcoded into Junkbuster were changed to go through a script
463 e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
464 The only other URLs left are the GNU GPL:
465 http://www.fsf.org/copyleft/gpl.html
467 http://ijbswa.sourceforge.net/
468 ... and various URLs which will be intercepted by Junkbuster anyway.
469 TODO: Still need to do something with the URLs in Junkbuster Corp's
470 copyright/trademark notice on the bottom of the show-proxy-args page.
471 - PCRE or GNU Regex is now a #define option.
474 *** Version 2.9.2 pre-Alpha Changes ***
476 - Andreas applied the latest version of the FORCE patch.
479 *** Version 2.9.1 pre-Alpha Changes ***
481 - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
482 (BTW: I think FORCE is precise enough, since loading remote
483 data is the whole purpose of a proxy..)
484 - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
485 is more elegant and looks like a hostname in the URL, it doesn't
486 make clear to the inexperienced user that the proxy is bypassed. It
487 also has a higher name collision risk.
488 - Filled in the function header templates for my functions in
489 parsers.c (again). They obviously got lost in our current
491 - Cut the credit for the §-referrer-option from the config file,
492 that Stefan had placed there.
493 - Improved the re_filterfile
496 *** Version 2.9.0 pre-Alpha Changes ***
498 - Now use PCRE, not GNU REGEX. I have not yet had chance to check the
499 syntax of the block/image/cookie file to ensure that they match what
500 is expected - however they seem to work.
501 - Replaced "configure" script with one generated by "autoconf". Also
502 use a header "config.h" (was ijbconfig.h in my previous release) for
503 the #defines. "config.h" is now generated with "autoheader" from
504 "acconfig.h" and "configure.in". (Note that to install you do not
505 need autoconf or autoheader - just run "./configure".)
506 To see command-line options, run "./configure --help".
507 This is my first ever autoconf script, so it has some rough edges
508 (how PCRE is handled is the roughest).
509 - Error logging code replaced with new module errlog.c, based on the
510 one from JunkbusterMT (but with the threading code removed).
511 - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
512 apply all of these, since I had already independently done conditional
513 popup file, conditional image file, and integration of popup code.
514 - ACL, Jar and trust files conditionally compiled.
515 - New source file headers.
516 - Various cosmetic changes. (But I have not consistently ordered the
517 config files - I think that's worthwhile, but it's 1am and I want to
519 - RCS tags on .h files.
520 - RCS tags are const char[] rather than const char *. (Saves 4 bytes
522 - VC++ project files renamed to vc_junkbuster.*.
523 - show-proxy-args now shows status of all conditionals, not just REGEX
524 - Various functions moved around. Most notably all the system-specific
525 sockets code which was spread between jcc.c, bind.c, and connect.c,
526 has been moved to "jbsockets.c". The non-system-specific code from
527 connect.c and socks4.c has been movet to "gateway.c". Also, the
528 config file loader and the global variables it writes to have been
529 moved to "loadcfg.c". (Maybe this should go into loaders.c?)
530 And candidate for the "worst filename ever" award is "miscutil.c",
531 which contains, well, miscellaneous utility functions like zalloc.
532 (Suggestions for a better name for this file are welcome!)
533 - Loaders now use a common function to read a line and skip comments,
534 and this function also stores the proxy_args.
535 - Added ./junkbuster --help (Not for Win32 GUI)
536 - Added ./junkbuster --version (Not for Win32 GUI)
537 - Win32 resources are now all marked as "U.S. English", rather than
538 being a mix of "U.S. English", "U.K. English" and "Irish English".
539 - Version number changes to 2.9.0
