6 - New trust entries are saved with a comment that contains the
7 trusted referring URL (Suggested by Daniel Griscom).
8 - Filter descriptions are HTML encoded automatically.
9 - New config option "split-large-forms" to work
10 around a browser bug that caused IE6 and IE7 to ignore
11 the Submit button on the edit-actions-for-url CGI page.
12 - New config option "allow-cgi-request-crunching" to allow
13 requests for Privoxy's CGI pages to be blocked, redirected
14 or (un)trusted like ordinary requests.
15 - Empty filter files no longer interrupt the filtering process
16 prematurely and are correctly listed on the show-status CGI page.
17 - New config option "accept-intercepted-requests" to combine
18 Privoxy with any packet filter to build an intercepting proxy
19 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
20 - fast-redirects{} catch redirects to https URLs as well.
21 - redirect{s@foo@bar@} can be used to redirect to a rewritten
22 version of the original URL.
23 - Trap unsupported gopher proxy requests.
24 - Fixed a bug in the User Manual delivery on Windows
25 (mingw32 only). Images now show up correctly and HTML
26 pages are no longer padded with garbage data.
27 - Fixed small memory leak in case of config file reloads.
28 - Only unlink the pidfile if it's actually used.
29 - Retries after connection problems with forced requests
31 - On Unix SIGABRT causes a core dump as expected and is no
32 longer treated as normal shutdown signal.
33 - The "access denied" CGI page is more descriptive and
34 allows to circumvent the referrer check.
35 - Updated PCRS to handle unexpected PCRE errors properly.
36 Fixed crashes that could occur if Privoxy was build
37 with external PCRE versions newer than Privoxy's internal
38 one. (Reported by Chung-chieh Shan)
39 - Fixed crashes with null bytes in PCRS replacement strings
40 (Patch provided by Felix Gröbert).
41 - Fixed crashes with header time randomization on mingw32.
42 - Added zlib support to filter content with gzip and deflate
43 encoding. (Patch provided by Wil Mahan)
44 - The CGI style sheet is no longer delivered if the referring
45 page isn't a Privoxy CGI page. This prevents a JavaScript-based
46 Privoxy detection "attack". Note that detecting Privoxy is
47 still possible through other ways and Privoxy was never intended
48 to be invisible anyway.
49 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
50 - The show-url-info CGI page displays a warning if Privoxy
51 is currently toggled off.
52 - The show-status CGI page suppresses the edit button
53 for action files if Privoxy has no write access.
54 - Socks errors are no longer handled by the CGI page for
55 DNS resolution failures.
56 - CGI pages use favicons to signal whether they are error
57 or control pages. This is useful if you rely heavily on
59 - Most CGI error pages react properly to HEAD requests.
60 - Requests with RFC 3253 HTTP methods (used by Subversion)
61 are accepted. (Patch provided by Petr Kadlec)
62 - New config option "templdir" to change the location
63 of the CGI templates to make sure customized templates
65 - Better handling of "HTTP/1.1 100 Continue" responses.
66 - "Crunch!" log messages (used when Privoxy answers requests
67 by itself) now also contain the reason.
68 - The show-url-info CGI page shows the forwarding settings.
69 - The background of the PNG pattern is transparent.
70 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
71 - Fixed crashes and possible action file corruptions
72 when lines containing hashes are written through the CGI editor.
73 - Fixes possible deadlocks and crashes on OpenBSD.
74 Patch provided by Ralf Horstmann.
75 - Supports dynamic filters which can contain variables.
76 - Supports tags to change the actions based on client or server headers.
77 - Incorrect actions are logged before program termination.
78 - The "actionsfile" syntax in the configuration file is consistent
79 with the rest of the configuration options and requires the
80 whole file name. This is an incompatible change, if you use
81 an old configuration file you might have to append ".action"
82 to your "actionsfile" directives.
83 - Dedicated filters and actions are used for header filtering.
84 "filter-client-headers" and "filter-client-headers" are no longer
85 supported, use server-header-filter{} and client-header-filter{}
87 - The CGI action editor allows to edit actionfiles with previously
88 forbidden characters like dots.
89 - New server-header filter: less-download-windows.
90 - New client-header taggers: text-requests and image-requests.
91 - The forward-override{} action allows to change the forwarding
92 settings based on client headers like the User-Agent, or the
94 - With the configuration file option "enforce-blocks" the
95 "go there anyway" mechanism can be disabled without recompiling
97 - On Unix-like systems nothing is logged to the console unless
98 an error occurs or Privoxy isn't running as daemon.
99 - More precise error messages in case of incorrect acl syntax.
100 - Logs a warning if filtering is enabled but impossible due
101 to lack of zlib support or use of the prevent-compression action.
102 - Less noisy handling of Cookie:" and "Connection:" headers.
103 - Don't ignore filter files if an previous filter file was empty.
104 - Improved error messages in case of connection problems.
105 - Fix a command-line-parsing bug that was introduced before 3.0.5
106 beta and caused Privoxy to treat the last argument as configuration
107 file if no configuration file was specified.
108 - Treat unknown command line options as fatal errors instead
109 of silently ignoring them.
110 - Use string functions with length checks more often.
111 - Don't log CONNECT requests twice.
112 - Log the source address for ACL-related connection drops.
113 - Log the reason why a request was crunched.
114 - Don't ignore applying filters if the server didn't
115 specify a Content-Type. Bug reported by Amuro Namie.
116 - Allow to rewrite the request destination behind the client's back.
117 - Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
118 - Rejected CONNECT requests are logged with log level info
119 (enabled by default) and the reason for the block.
120 - New command line option "--pre-chroot-nslookup hostname" to
121 intialize the resolver library before chroot'ing. On some systems this
122 reduces the number of files that must be copied into the chroot tree.
123 (Patch provided by Stephen Gildea)
124 - Minor code clean-ups, filter and action file updates.
125 (Some of them reported by Davide Alberani, Markus Elfring,
126 Stefan Huehner and Adam Piggott)
128 *** Version 3.0.6 ***
130 - New content filters: no-ping, google, msn, yahoo and blogspot.
131 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
132 and hide-tor-exit-notation.
133 - The special header "X-Filter: No" now disables header filtering as well.
134 - Improved the filters img-reorder, js-annoyances, webbugs,
135 banners-by-size, banners-by-link and ie-exploits to make them
136 less likely to break anything.
137 - Removed outdated URL patterns in default.action and added new ones.
138 - Added redirection from http://p.p/user-manual to http://p.p/user-manual/

147 http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
148 following new or significantly improved actions (among many
151 content-type-overwrite{}
152 crunch-client-header{string}

162 hide-if-modified-since
163 hide-referrer{conditional-block}
164 overwrite-last-modified{}

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

187 (for trustfile users).
189 *** Version 3.0.3 ***
191 - Fixed yet another two memory leaks. Process growth seems stopped now.
192 - Further tightened security against malicious toggle-off links.
193 - Excluded text/plain MIME types from filtering. This fixes a
194 couple of client-crashing, download corruption and
195 Privoxy performance issues, whose root cause lies in
196 web servers labelling content of unknown type as text/plain.
197 - Assorted fixes for POSIX compliance, signal handling, graceful
198 termination, compiler warnings, OSX support, Win32 systray,
199 error logging, hostname wildcards, correct detection of NetBSD.
200 - Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs
201 including the notorious "blank page" problem.

217 img-reorder, banners-by-size, banners-by-link, webbugs, refresh-tags,
218 html-annoyances, content-cookies and fun filters
219 - Replaced filter "popups" by choice between two modes:
220 - "unsolicited-popups" tries to catch only the unsolicited ones
221 - "all-popups" tries to kill them all (as before)
222 - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
223 - New filter "jumping-windows" that prevents windows from resizing
224 and moving themselves

228 all filters for exploits shall be collected
229 - Improved cookie logging
230 - Rewrote make install target. Added uninstall and install-strip
232 - Fixed a potential (application-level, NOT OS-level!) security
233 problem involving remote toggling and action file manipulation
234 by mailicious websites.
235 - Added ability to chroot (thanks to Sviatoslav Sviridov)

365 *** Version 2.9.3 pre-Alpha Changes ***
367 - Amiga support (completely untested by me - I don't have an Amiga)
368 - "tinygif 3" support (redirects blocked images to a specified URL, so
369 the browser doesn't have to load and cache many copies of the same
371 - one case where there were both local and global "referrer" variables
372 (yuck!) clarified by renaming the local one to "refer".
373 - Fixed some places where close() was used instead of close_socket().
374 Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
375 - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
376 FORCE_LOAD_PREFIX. Needs fixing properly.
377 - Most URLs hardcoded into Junkbuster were changed to go through a script
378 e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
379 The only other URLs left are the GNU GPL:
380 http://www.fsf.org/copyleft/gpl.html
382 http://ijbswa.sourceforge.net/
383 ... and various URLs which will be intercepted by Junkbuster anyway.
384 TODO: Still need to do something with the URLs in Junkbuster Corp's
385 copyright/trademark notice on the bottom of the show-proxy-args page.
386 - PCRE or GNU Regex is now a #define option.
389 *** Version 2.9.2 pre-Alpha Changes ***
391 - Andreas applied the latest version of the FORCE patch.
394 *** Version 2.9.1 pre-Alpha Changes ***
396 - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
397 (BTW: I think FORCE is precise enough, since loading remote
398 data is the whole purpose of a proxy..)
399 - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
400 is more elegant and looks like a hostname in the URL, it doesn't
401 make clear to the inexperienced user that the proxy is bypassed. It
402 also has a higher name collision risk.
403 - Filled in the function header templates for my functions in
404 parsers.c (again). They obviously got lost in our current
406 - Cut the credit for the §-referrer-option from the config file,
407 that Stefan had placed there.
408 - Improved the re_filterfile
411 *** Version 2.9.0 pre-Alpha Changes ***
413 - Now use PCRE, not GNU REGEX. I have not yet had chance to check the
414 syntax of the block/image/cookie file to ensure that they match what
415 is expected - however they seem to work.
416 - Replaced "configure" script with one generated by "autoconf". Also
417 use a header "config.h" (was ijbconfig.h in my previous release) for
418 the #defines. "config.h" is now generated with "autoheader" from
419 "acconfig.h" and "configure.in". (Note that to install you do not
420 need autoconf or autoheader - just run "./configure".)
421 To see command-line options, run "./configure --help".
422 This is my first ever autoconf script, so it has some rough edges
423 (how PCRE is handled is the roughest).
424 - Error logging code replaced with new module errlog.c, based on the
425 one from JunkbusterMT (but with the threading code removed).
426 - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
427 apply all of these, since I had already independently done conditional
428 popup file, conditional image file, and integration of popup code.
429 - ACL, Jar and trust files conditionally compiled.
430 - New source file headers.
431 - Various cosmetic changes. (But I have not consistently ordered the
432 config files - I think that's worthwhile, but it's 1am and I want to
434 - RCS tags on .h files.
435 - RCS tags are const char[] rather than const char *. (Saves 4 bytes
437 - VC++ project files renamed to vc_junkbuster.*.
438 - show-proxy-args now shows status of all conditionals, not just REGEX
439 - Various functions moved around. Most notably all the system-specific
440 sockets code which was spread between jcc.c, bind.c, and connect.c,
441 has been moved to "jbsockets.c". The non-system-specific code from
442 connect.c and socks4.c has been movet to "gateway.c". Also, the
443 config file loader and the global variables it writes to have been
444 moved to "loadcfg.c". (Maybe this should go into loaders.c?)
445 And candidate for the "worst filename ever" award is "miscutil.c",
446 which contains, well, miscellaneous utility functions like zalloc.
447 (Suggestions for a better name for this file are welcome!)
448 - Loaders now use a common function to read a line and skip comments,
449 and this function also stores the proxy_args.
450 - Added ./junkbuster --help (Not for Win32 GUI)
451 - Added ./junkbuster --version (Not for Win32 GUI)
452 - Win32 resources are now all marked as "U.S. English", rather than
453 being a mix of "U.S. English", "U.K. English" and "Irish English".
454 - Version number changes to 2.9.0
