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

216 - Integrated Fabian Keil's extensive patch. See:
217 http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
218 following new or significantly improved actions (among many
221 content-type-overwrite{}
222 crunch-client-header{string}
224 crunch-server-header{string}
225 fast-redirects{check-decoded-url}
226 filter-client-headers
227 filter-server-headers
229 handle-as-empty-document
230 hide-accept-language{}
231 hide-content-disposition{}
232 hide-if-modified-since
233 hide-referrer{conditional-block}
234 overwrite-last-modified{}
236 treat-forbidden-connects-like-blocks
238 - Standard-compliant clients are prevented from displaying cached
239 copies of Privoxy's error messages after the cause of the problem
241 - Improved DNS error handling.
242 - Multiple filter files can now be specified in config.
243 - Added jpeg filtering to defend against MS jpeg vulnerability MS04-028

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

278 - Fixed two memory leaks, one serious
279 - Fixed bug in pcrs which could cause crashes with user-defined filters

284 - Refined the default action file through >400 items of user feedback
286 - Assorted refinements, optimizations and fixes in the js-annoyances,
287 img-reorder, banners-by-size, banners-by-link, webbugs, refresh-tags,
288 html-annoyances, content-cookies and fun filters
289 - Replaced filter "popups" by choice between two modes:
290 - "unsolicited-popups" tries to catch only the unsolicited ones
291 - "all-popups" tries to kill them all (as before)
292 - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
293 - New filter "jumping-windows" that prevents windows from resizing
294 and moving themselves
295 - New filter "demoronizer" which fixes MS's abuse of std charsets
296 (common cases anyway).
297 - Replaced "nimda" with more general "ie-exploits" filter in which
298 all filters for exploits shall be collected
299 - Improved cookie logging
300 - Rewrote make install target. Added uninstall and install-strip
302 - Fixed a potential (application-level, NOT OS-level!) security
303 problem involving remote toggling and action file manipulation
304 by mailicious websites.
305 - Added ability to chroot (thanks to Sviatoslav Sviridov)
306 - Added more action aliases for prehistoric action names
307 - Add Slackware support to Makefile.

321 - Added workaround for IE bug that broke CGI interface
322 - Bugfix: String actions now reliably editable through CGI interface
323 - Three filters fixed (again!)
324 - Assorted small fixes and doc enhancements
326 *** Version 2.9.16 ***
328 - Major revamp of default.action to get rid of years of cruft.

338 - Actions files are changed to: default.action, standard.action, and
339 user.action. user.action is for personal/local configuration.

373 - More CGI actions editor fixes and improvements.
374 - Win32 command line fix ups.
375 - re_filterfile now has modular sections that can be activated on a
376 per site basis. Some new goodies there too.
377 - +filter now takes arguments to match FILTER sections in re_filterfile
378 for even more flexibility.
379 - Added a new image blocker option: +image-blocker{pattern}, which
380 displays a checkerboard patthern and scales better than the logo.
381 - PNG images will be used in place of GIF for JB built-in images
382 if configured with --enable-no-gif.

395 to the specified user.
396 - Signal handling cleanups (*nix).
397 - CGI actions editor improvements and fixes.
398 - Error handling improvements, especially out of memory.
399 - Default re_filterfile fix that caused spurious IJB logos

402 - Various other minor fixes.
405 *** Version 2.9.11 Beta Changes ***
407 - Add "session" cookie concept where cookies exist for the life
408 of that browser session only (ie never goes to disk).
409 - Checks for correct header length.
410 - Fix user:pass@host.domain.com auth bug.
411 - Better signal handling on *nix.
412 - Fix CFLAGS hard-coded in configure.in

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