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

12 - Requests for Privoxy's CGI pages can be blocked, redirected
13 or (un)trusted like ordinary requests.
14 - Empty filter files no longer interrupt the filtering process
15 prematurely and are correctly listed on the show-status CGI page.
16 - New config option "accept-intercepted-requests" to combine
17 Privoxy with any packet filter to build an intercepting proxy
18 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
19 - fast-redirects{} catch redirects to https URLs as well.
20 - redirect{s@foo@bar@} can be used to redirect to a rewritten
21 version of the original URL.
22 - Trap unsupported gopher proxy requests.

27 - Only unlink the pidfile if it's actually used.
28 - Retries after connection problems with forced requests
30 - On Unix SIGABRT causes a coredump as expected and is no
31 longer treated as normal shutdown signal.
32 - The "access denied" CGI page is more descriptive and
33 allows to circumvent the referrer check.
34 - Updated PCRS to handle unexpected PCRE errors properly.
35 Fixed crashes that could occur if Privoxy was build

41 - Added zlib support to filter content with gzip and deflate
42 encoding. (Patch provided by Wil Mahan)
43 - The CGI style sheet is no longer delivered if the referring
44 page isn't a Privoxy CGI page. This prevents a JavaScript-based
45 Privoxy detection "attack".
46 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
47 - The show-url-info CGI page displays a warning if Privoxy
48 is currently toggled off.
49 - The show-status CGI page suppresses the edit button
50 for action files if Privoxy has no write access.
51 - If Privoxy creates new Trustfile entries, a comment
52 with the trusted referrer is added. (Suggested by Daniel Griscom)
53 - Socks errors are no longer handled by the CGI page for
54 DNS resolution failures.
55 - CGI pages use favicons to signal whether they are error
56 or control pages. This is useful if you rely heavily on
58 - Most CGI error pages react properly to HEAD requests.
59 - Requests with RFC 3253 HTTP methods (used by Subversion)
60 are accepted. (Patch provided by Petr Kadlec)

66 by itself) now also contain the reason.
67 - The show-url-info CGI page shows the forwarding settings.
68 - The background of the PNG pattern is transparent.
69 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
70 - Fixed crashes and possible action file corruptions
71 when lines containing hashes are written through the CGI editor.
72 - Minor code clean-ups, filter and action file updates.
73 (Some of them reported by Davide Alberani, Markus Elfring
78 - New content filters: no-ping, google, msn, yahoo and blogspot.
79 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
80 and hide-tor-exit-notation.
81 - The special header "X-Filter: No" now disables header filtering as well.
82 - Improved the filters img-reorder, js-annoyances, webbugs,
83 banners-by-size, banners-by-link and ie-exploits to make them
84 less likely to break anything.

139 - Fixed yet another two memory leaks. Process growth seems stopped now.
140 - Further tightened security against malicious toggle-off links.
141 - Excluded text/plain MIME types from filtering. This fixes a
142 couple of client-crashing, download corruption and
143 Privoxy performance issues, whose root cause lies in
144 web servers labelling content of unknown type as text/plain.
145 - Assorted fixes for POSIX compliance, signal handling, graceful
146 termination, compiler warnings, OSX support, Win32 systray,
147 error logging, hostname wildcards, correct detection of NetBSD.
148 - Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs

171 - New filter "jumping-windows" that prevents windows from resizing
172 and moving themselves

177 - Improved cookie logging
178 - Rewrote make install target. Added uninstall and install-strip

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