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

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

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

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

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

324 - Added workaround for IE bug that broke CGI interface
325 - Bugfix: String actions now reliably editable through CGI interface
326 - Three filters fixed (again!)
327 - Assorted small fixes and doc enhancements
329 *** Version 2.9.16 ***

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

356 - #include mechansim for common text in templates
357 - Various other minor fixes.

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

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

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