3 --------------------------------------------------------------------
4 *** Version 3.0.16 Stable ***
6 - Added the config file option handle-as-empty-doc-returns-ok to
7 work around Firefox bug #492459, which causes Firefox to hang
8 if JavaScripts are blocked in certain situations. The option is
9 enabled in the default config file.
10 - Added the config option default-server-timeout to control the
11 assumed default server timeout. Since Privoxy no longer returns
12 an error message for connection resets on reused client connections,
13 assuming larger server timeout values appears to actually work
14 pretty well as long as connections aren't shared.
15 - Added optional support for FreeBSD's accf_http(9). Use the
16 configure option --enable-accept-filter to enable it.
17 - Added fancier Privoxy icons for win32. Contributed by Jeff H.
18 - In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
19 - Resolve localhost using whatever address family the operating
20 system feels like. Previous betas would try to use IPv4 as this
21 is what most users expect, but this didn't work reliable on
23 - In the action lists on CGI pages, actions and their parameters are
24 no longer separated with a space. The action file parser doesn't
25 actually allow this and will throw an invalid syntax error if actions
26 and parameters in the action files are separated. Not adding the
27 spaces means copy and pasting CGI output into the action files works.
28 - The default keep-alive timeout has been reduced to 5 seconds to work
29 around hangs in clients that treat the proxy like any other host and
30 stop allowing any new connections if the "maximum number of
31 connections per host" is reached.
32 - Several webbug URLs that look like they are leading to images are now
33 blocked as image instead of empty documents. Doing the latter causes
34 WebKit-based clients to show a "missing image" icon which may mess up
36 - The no-such-domain template if used if for DNS resolution
37 problems with FEATURE_IPV6_SUPPORT enabled. Previously the
38 connect-failed template was used. Reported by 'zebul666'.
39 - Accepts quoted expiration dates even though RFC 2109 10.1.2
40 doesn't seem to allow them. Reported anonymously.
41 - Don't try to forget connections if connection sharing is disabled.
42 This wasn't a real problem but caused an unnecessary log message.
43 - The still undocumented --enable-extended-host-patterns configure
44 option has a better description.
45 - Fixed an error message that would claim a write to the server
46 failed when actually writing to the client failed.
47 - Log the crunch reason before trying to write to the client.
48 The log is easier to read that way.
49 - Several log messages about client connections also mention
51 - handle-as-empty-document no longer depends on the image blocking
53 - Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
54 - uagen, a Firefox User-Agent generator for Privoxy and Mozilla
55 browsers has been imported and is available in the tarballs
57 - The scripts in the tools directory treat unknown parameters
60 *** Version 3.0.15 Beta ***
62 - In case of missing server data, no error message is send to the
63 client if the request arrived on a reused connection. The client
64 is then supposed to silently retry the request without bothering
65 the user. This should significantly reduce the frequency of the
66 "No server or forwarder data received" error message many users
68 - More reliable detection of prematurely closed client sockets
69 with keep-alive enabled.
70 - FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
71 FEATURE_CONNECTION_SHARING and now available on
73 - Improved handling of POST requests on reused connections.
74 Should fix problems with stalled connections after submitting
75 form data with some browser configurations.
76 - Fixed various latency calculation issues.
77 - Allows the client to pass NTLM authentication requests to a
78 forwarding proxy. This was already assumed and hinted to work
79 in 3.0.13 beta but actually didn't. Now it's confirmed to work
80 with IE, Firefox and Chrome.
81 Thanks to Francois Botha and Wan-Teh Chang
82 - Fixed a calculation problem if receiving the server headers
83 takes more than two reads, that could cause Privoxy to terminate
84 the connection prematurely. Reported by Oliver.
85 - Compiles again on platforms such as OpenBSD and systems
86 using earlier glibc version that don't support AI_ADDRCONFIG.
87 Anonymously submitted in #2872591.
88 - A bunch of MS VC project files and Suse and Redhat RPM spec
89 files have been removed as they were no longer maintained for
91 - Overly long action lines are properly rejected with a proper
92 error message. Previously they would be either rejected as
93 invalid or cause a core dump through abort().
94 - Already timed-out connections are no longer temporarily remembered.
95 They weren't reused anyway, but wasted a socket slot.
96 - len refers to the number of bytes actually read which might
97 differ from the ones received. Adjust log messages accordingly.
98 - The optional JavaScript on the CGI page uses encodeURIComponent()
99 instead of escape() which doesn't encode all characters that matter.
100 Anonymously reported in #2832722.
101 - Fix gcc45 warnings in decompress_iob().
102 - Various log message improvements.
103 - Privoxy-Regression-Test supports redirect tests.
104 - Privoxy-Log-Parser can gather some connection statistics.
106 *** Version 3.0.14 Beta ***
108 - The latency is taken into account when evaluating whether or not to
109 reuse a connection. This should significantly reduce the number of
110 connections problems several users reported.
111 - If the server doesn't specify how long the connection stays alive,
112 Privoxy errs on the safe side of caution and assumes it's only a second.
113 - The error pages for connection timeouts or missing server data use a
114 Last-Modified date in the past. Retry attempts are detected and Privoxy
115 removes the If-Modified-Since header to prevent the server from responding
116 with status code 304 in which case the client would reuse the error message.
117 - Setting keep-alive-timeout to 0 disables keep-alive support. Previously
118 Privoxy would claim to allow persistence but not reuse the connection.
119 - Pipelined requests are less likely to be mistaken for the request
120 body of the previous request. Note that Privoxy still has no real
121 pipeline support and will either serialize pipelined requests or
122 drop them in which case the client has to resent them.
123 - Fixed a crash on some Windows versions when header randomization
124 is enabled and the date couldn't be parsed.
125 - Privoxy's keep-alive timeout for the current connection is reduced
126 to the one specified in the client's Keep-Alive header.
127 - For HTTP/1.1 requests, Privoxy implies keep-alive support by not
128 setting any Connection header instead of using 'Connection: keep-alive'.
129 - If the socket isn't reusable, Privoxy doesn't temporarily waste
130 a socket slot to remember the connection.
131 - If keep-alive support is disabled but compiled in, the client's
132 Keep-Alive header is removed.
133 - Fixed a bug on mingw32 where downloading large files failed if
134 keep-alive support was enabled.
135 - Fixed a bug that (at least theoretically) could cause log
136 timestamps to be occasionally off by about a second.
137 - No Proxy-Connection header if added if there already is one.
138 - The configure script respects the $PATH variable when searching
141 *** Version 3.0.13 Beta ***
143 - Added IPv6 support. Thanks to Petr Pisar who not only provided
144 the initial patch but also helped a lot with the integration.
145 - Added client-side keep-alive support.
146 - The connection sharing code is only used if the connection-sharing
148 - The max-client-connections option has been added to restrict
149 the number of client connections below a value enforced by
150 the operating system.
151 - Fixed a regression reintroduced in 3.0.12 that could cause
152 crashes on mingw32 if header date randomization was enabled.
153 - Compressed content with extra fields couldn't be decompressed
154 and would get passed to the client unfiltered. This problem
155 has only be detected through statical analysis with clang as
156 nobody seems to be using extra fields anyway.
157 - If the server resets the Connection after sending only the headers
158 Privoxy forwards what it got to the client. Previously Privoxy
159 would deliver an error message instead.
160 - Error messages in case of connection timeouts use the right
162 - If spawning a child to handle a request fails, the client
163 gets an error message and Privoxy continues to listen for
164 new requests right away.
165 - The error messages in case of server-connection timeouts or
166 prematurely closed server connections are now template-based.
167 - If zlib support isn't compiled in, Privoxy no longer tries to
168 filter compressed content unless explicitly asked to do so.
169 - In case of connections that are denied based on ACL directives,
170 the memory used for the client IP is no longer leaked.
171 - Fixed another small memory leak if the client request times out
172 while waiting for client headers other than the request line.
173 - The client socket is kept open until the server socket has
174 been marked as unused. This should increase the chances that
175 the still-open connection will be reused for the client's next
176 request to the same destination. Note that this only matters
177 if connection-sharing is enabled.
178 - A TODO list has been added to the source tarballs to give potential
179 volunteers a better idea of what the current goals are. Donations
180 are still welcome too: http://www.privoxy.org/faq/general.html#DONATE
182 *** Version 3.0.12 ***
184 - The socket-timeout option now also works on platforms whose
185 select() implementation modifies the timeout structure.
186 Previously the timeout was triggered even if the connection
187 didn't stall. Reported by cyberpatrol.
188 - The Connection: keep-alive code properly deals with files
189 larger than 2GB. Previously the connection was closed too
191 - The content length for files above 2GB is logged correctly.
192 - The user-manual directive on the show-status page links to
193 the documentation location specified with the directive,
194 not to the Privoxy website.
195 - When running in daemon mode, Privoxy doesn't log anything
196 to the console unless there are errors before the logfile
198 - The show-status page prints warnings about invalid directives
199 on the same line as the directives themselves.
200 - Fixed several justified (but harmless) compiler warnings,
201 mostly on 64 bit platforms.
202 - The mingw32 version explicitly requests the default charset
203 to prevent display problems with some fonts available on more
204 recent Windows versions. Patch by Burberry.
205 - The mingw32 version uses the Privoxy icon in the alt-tab
206 windows. Patch by Burberry.
207 - The timestamp and the thread id is omitted in the "Fatal error"
208 message box on mingw32.
209 - Fixed two related mingw32-only buffer overflows. Triggering
210 them required control over the configuration file, therefore
211 this isn't seen as a security issue.
212 - In verbose mode, or if the new option --show-skipped-tests
213 is used, Privoxy-Regression-Test logs skipped tests and the
216 *** Version 3.0.11 ***
218 - On most platforms, outgoing connections can be kept alive and
219 reused if the server supports it. Whether or not this improves
220 things depends on the connection.
221 - When dropping privileges, membership in supplementary groups
222 is given up as well. Not doing that can lead to Privoxy running
223 with more rights than necessary and violates the principle of
224 least privilege. Users of the --user option are advised to update.
225 Thanks to Matthias Drochner for reporting the problem,
226 providing the initial patch and testing the final version.
227 - Passing invalid users or groups with the --user option
228 didn't lead to program exit. Regression introduced in 3.0.7.
229 - The match all section has been moved from default.action
230 to a new file called match-all.action. As a result the
231 default.action no longer needs to be touched by the user
232 and can be safely overwritten by updates.
233 - The standard.action file has been removed. Its content
234 is now part of the default.action file.
235 - In some situations the logged content length was slightly too low.
236 - Crunched requests are logged with their own log level.
237 If you used "debug 1" in the past, you'll probably want
238 to additionally enable "debug 1024", otherwise only passed
239 requests will be logged. If you only care about crunched
240 requests, simply replace "debug 1" with "debug 1024".
241 - The crunch reason has been moved to the beginning of the
242 crunch message. For HTTP URLs, the protocol is logged as well.
243 - Log messages are shortened by printing the thread id on its
244 own (as opposed to putting it inside the string "Privoxy()").
245 - The config option socket-timeout has been added to control
246 the time Privoxy waits for data to arrive on a socket.
247 - Support for remote toggling is controlled by the configure
248 option --disable-toggle only. In previous versions it also
249 depended on the action editor and thus configuring with the
250 --disable-editor option would disable remote toggling support
252 - Requests with invalid HTTP versions are rejected.
253 - The template symbol @date@ can be used to include a date(1)-like
254 time string. Initial patch submitted by Endre Szabo.
255 - Responses from shoutcast servers are accepted again.
256 Problem reported and fix suggested by Stefan.
257 - The hide-forwarded-for-headers action has been replaced with
258 the change-x-forwarded-for{} action which can also be used to
259 add X-Forwarded-For headers. The latter functionality already
260 existed in Privoxy versions prior to 3.0.7 but has been removed
261 as it was often used unintentionally (by not using the
262 hide-forwarded-for-headers action).
263 - A "clear log" view option was added to the mingw32 version
264 to clear out all of the lines in the Privoxy log window.
265 Based on a patch submitted by T Ford.
266 - The mingw32 version uses "critical sections" now, which prevents
267 log message corruption under load. As a side effect, the
268 "no thread-safe PRNG" warning could be removed as well.
269 - The mingw32 version's task bar icon is crossed out and
270 the color changed to gray if Privoxy is toggled off.
272 *** Version 3.0.10 ***
274 - Ordinary configuration file changes no longer cause program
275 termination on OS/2 if the name of the logfile hasn't been
276 changed as well. This regression probably crept in with the
277 logging improvements in 3.0.7. Reported by Maynard.
278 - The img-reorder filter is less likely to mess up JavaScript code in
279 img tags. Problem and solution reported by Glenn Washburn in #2014552.
280 - The source tar ball now includes Privoxy-Log-Parser,
281 a syntax-highlighter for Privoxy logs. For fancy screenshots see:
282 http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
283 Documentation is available through perldoc(1).
285 *** Version 3.0.9 Beta ***
287 - Added SOCKS5 support (with address resolution done by
288 the SOCKS5 server). Patch provided by Eric M. Hopper.
289 - The "blocked" CGI pages include a block reason that was
290 provided as argument to the last-applying block action.
291 - If enable-edit-actions is disabled (the default since 3.0.7 beta)
292 the show-status page hides the edit buttons and explains why.
293 Previously the user would get the "this feature has been disabled"
294 message after using the edit button.
295 - Forbidden CONNECT requests are treated like blocks by default.
296 The now-pointless treat-forbidden-connects-like-blocks action
298 - Not enabling limit-connect now allows CONNECT requests to all ports.
299 In previous versions it would only allow CONNECT requests to port 443.
300 Use +limit-connect{443} if you think you need the old default behaviour.
301 - The CGI editor gets turned off after three edit requests with invalid
302 file modification timestamps. This makes life harder for attackers
303 who can leverage browser bugs to send fake Referers and intend to
304 brute-force edit URLs.
305 - Action settings for multiple patterns in the same section are
306 shared in memory. As a result these sections take up less space
307 (and are loaded slightly faster). Problem reported by Franz Schwartau.
308 - Linear white space in HTTP headers will be normalized to single
309 spaces before parsing the header's content, headers split across
310 multiple lines get merged first. This should prevent problems like:
311 * letting the session-cookies-only action slip
312 some Cookies through unmodified,
313 * only suppressing the first line of a header,
314 thus creating an invalid one, and
315 * to incorrectly block headers with valid timestamps
316 that weren't properly recognized.
317 Headers that could trigger these problems are unlikely to appear
318 in "normal" web traffic, but could be intentionally generated to
319 fool some of Privoxy's header parsers.
320 - Host information is gathered outside the main thread so it's less
321 likely to delay other incoming connections if the host is misconfigured.
322 - New config option "hostname" to use a hostname other than
323 the one returned by the operating system. Useful to speed-up responses
324 for CGI requests on misconfigured systems. Requested by Max Khon.
325 - The CGI editor supports the "disable all filters of this type"
326 directives "-client-header-filter", "-server-header-filter",
327 "-client-header-tagger" and "-server-header-tagger".
328 - Fixed false-positives with the link-by-url filter and URLs that
329 contain the pattern "/jump/".
330 - The less-download-windows filter no longer messes
331 "Content-Type: application/x-shockwave-flash" headers up.
332 - In the show-url-info page's "Final results" section active and
333 inactive actions are listed separately. Patch provided by Lee.
334 - The GNUmakefile supports the DESTDIR variable. Patch for
335 the install target submitted by Radoslaw Zielinski.
336 - Embedding the content of configuration files in the show-status
337 page is significantly faster now. For a largish action file (1 MB)
338 a speedup of about 2450 times has been measured. This is mostly
339 interesting if you are using large action files or regularly use
340 Privoxy-Regression-Test while running Privoxy through Valgrind,
341 for stock configuration files it doesn't really matter.
342 - If zlib support is unavailable and there are content
343 filters active but the prevent-compression action is disabled,
344 the show-url-info page includes a warning that compression
345 might prevent filtering.
346 - The show-url-info page provides an OpenSearch Description that
347 allows to access the page through browser search plugins.
348 - Custom client-header filters that rewrite the request line
349 incorrectly no longer cause Privoxy to crash. Reported by din_a4.
350 - The obsolete kill-popups action has been removed as the
351 PCRS-based popup filters can do the same and are slightly
353 - The inspect-jpegs action has been removed.
354 - The send-wafer and send-vanilla-wafer actions have been removed.
355 They weren't particular useful and their behaviour could be emulated
356 with add-header anyway.
357 - Privoxy-Regression-Test has been significantly improved.
358 - Most sections in the default.action file contain tests for
359 Privoxy-Regression-Test to verify that they are working as intended.
360 - Parts of Privoxy have been refactored to increase maintainability.
361 - Building with zlib (if available) is done by default.
363 *** Version 3.0.8 ***
365 - Fixed a small memory leak when listen-address only specifies the port.
366 - The source tar balls now include Privoxy-Regression-Test which
367 (upon other things) can be used to automatically detect some
368 packaging problems. Packagers are welcome to give it a try.
369 - Reverted a change in 3.0.7 that caused path patterns to be checked
370 even if the host pattern match already failed. While this doesn't
371 noticeable affect the performance, it makes it less likely to run
372 out of stack space with overly-complex path patterns the user might
374 - Updated the msn, yahoo and google filters to work as advertised again.
375 - The warning message shown by the show-status CGI page is easier to
376 understand. Previously it wasn't clear that the error message
377 is shown below the invalid directive. (Reported by Lee)
378 - When regenerating Content-Disposition headers the more common
379 spelling is used for the name. Previously it was written without caps.
380 - Less confusing log message if the content type isn't overwritten
381 because force-text-type wasn't used but the old type doesn't look
382 like content that would be filtered normally.
383 - Better log messages if the user tries to execute filters that
385 - Treat the non-standard Request-Range headers like standard range
386 headers and suppress them if content filtering is enabled.
387 - Prevent the log messages for CONNECT requests to unacceptable
388 ports from printing the limit-connect argument as [null] if
389 limit-connect hasn't been explicitly enabled.
390 - Don't disable the mingw32 log window if the logfile directive
391 isn't used. While it was an intentional change in 3.0.7 at least
392 one user perceived it as a regression and the same effect can
393 be achieved by disabling all debug directives.
394 - Fixed two minor problems related to the win32 build process: a css
395 file was not being in the installer and the trustfile comment in the
396 config.txt referenced a nonexisting file
397 - Minor documentation fixes.
399 *** Version 3.0.7 Beta ***
401 - Added zlib support to filter content with gzip and deflate
402 encoding. (Patch provided by Wil Mahan)
403 - Dedicated filters and actions are used for header filtering.
404 "filter-client-headers" and "filter-client-headers" are no longer
405 supported, use server-header-filter{} and client-header-filter{}
407 - Tags can be used to change actions based on HTTP headers.
408 - New server-header filter: less-download-windows.
409 - New client-header taggers: css-requests, image-requests,
410 client-ip-address, http-method, allow-post, complete-url,
411 user-agent and privoxy-control.
412 - New server-header taggers: content-type and privoxy-control.
413 - The forward-override{} action allows to change the forwarding
414 settings through the action files, for example based on client
415 headers like the User-Agent, or the request origin.
416 - Socks errors are no longer handled by the CGI page for
417 DNS resolution failures.
418 - CGI pages use favicons to signal whether they are error
419 or control pages. This is useful if you rely heavily on
421 - The show-url-info CGI page shows the forwarding settings.
422 - "Crunch!" log messages (used when Privoxy answers requests
423 by itself) now also contain the reason.
424 - Allow to rewrite the request destination behind the client's back.
425 - Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
426 - Fixes possible deadlocks and crashes on OpenBSD.
427 Patch provided by Ralf Horstmann.
428 - The CGI action editor allows to edit actionfiles with previously
429 forbidden characters like dots.
430 - New trust entries are saved with a comment that contains the
431 trusted referring URL (Suggested by Daniel Griscom).
432 - Filter descriptions are HTML encoded automatically.
433 - New config option "split-large-forms" to work
434 around a browser bug that caused IE6 and IE7 to ignore
435 the Submit button on the edit-actions-for-url CGI page.
436 - New config option "allow-cgi-request-crunching" to allow
437 requests for Privoxy's CGI pages to be blocked, redirected
438 or (un)trusted like ordinary requests.
439 - Empty filter files no longer interrupt the filtering process
440 prematurely and are correctly listed on the show-status CGI page.
441 - New config option "accept-intercepted-requests" to combine
442 Privoxy with any packet filter to build an intercepting proxy
443 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
444 - fast-redirects{} catch redirects to https URLs as well.
445 - redirect{s@foo@bar@} can be used to redirect to a rewritten
446 version of the original URL.
447 - Trap unsupported gopher proxy requests.
448 - Fixed a bug in the User Manual delivery on Windows
449 (mingw32 only). Images now show up correctly and HTML
450 pages are no longer padded with garbage data.
451 - Fixed several minor memory leaks, most of them discovered with Valgrind.
452 - Only unlink the pidfile if it's actually used.
453 - Retries after connection problems with forced requests
454 aren't blocked again.
455 - On Unix SIGABRT causes a core dump as expected and is no
456 longer treated as normal shutdown signal.
457 - The "access denied" CGI page is more descriptive and
458 allows retries to circumvent the referrer check.
459 - Updated PCRS to handle unexpected PCRE errors properly.
460 Fixed crashes that could occur if Privoxy was build
461 with external PCRE versions newer than Privoxy's internal
462 one. (Reported by Chung-chieh Shan)
463 - Fixed crashes with null bytes in PCRS replacement strings
464 (Patch provided by Felix Gröbert).
465 - Fixed crashes with header time randomization on mingw32.
466 - The CGI style sheet is no longer delivered if the referring
467 page isn't a Privoxy CGI page. This prevents a JavaScript-based
468 Privoxy detection "attack". Note that detecting Privoxy is
469 still possible through other ways and Privoxy was never intended
470 to be invisible anyway.
471 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
472 - The show-url-info CGI page displays a warning if Privoxy
473 is currently toggled off.
474 - The show-status CGI page suppresses the edit button
475 for action files if Privoxy has no write access.
476 - Most CGI error pages react properly to HEAD requests.
477 - Requests with RFC 3253 HTTP methods (used by Subversion)
478 are accepted. (Patch provided by Petr Kadlec)
479 - New config option "templdir" to change the location
480 of the CGI templates to make sure customized templates
482 - Better handling of "HTTP/1.1 100 Continue" responses.
483 - The background of the PNG pattern is transparent.
484 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
485 - Fixed crashes and possible action file corruptions
486 when lines containing hashes are written through the CGI editor.
487 - Supports dynamic filters which can contain variables.
488 - Supports tags to change the actions based on client or server headers.
489 - Incorrect actions are logged before program termination.
490 - The "actionsfile" syntax in the configuration file is consistent
491 with the rest of the configuration options and requires the
492 whole file name. This is an incompatible change, if you use
493 an old configuration file you might have to append ".action"
494 to your "actionsfile" directives.
495 - With the configuration file option "enforce-blocks" the
496 "go there anyway" mechanism can be disabled without recompiling
498 - More precise error messages in case of incorrect acl syntax.
499 - Logs a warning if filtering is enabled but impossible due
500 to lack of zlib support or use of the prevent-compression action.
501 - Less noisy handling of Cookie:" and "Connection:" headers.
502 - Improved error messages in case of connection problems.
503 - Fix a command-line-parsing bug that was introduced before 3.0.5
504 beta and caused Privoxy to treat the last argument as configuration
505 file if no configuration file was specified.
506 - Treat unknown command line options as fatal errors instead
507 of silently ignoring them.
508 - Use string functions with length checks more often.
509 - Don't log CONNECT requests twice.
510 - Allow to log the source address for ACL-related connection drops.
511 - Don't ignore applying filters if the server didn't
512 specify a Content-Type. Bug reported by Amuro Namie.
513 - Rejected CONNECT requests are logged with log level info
514 (enabled by default) and the reason for the block.
515 - New command line option "--pre-chroot-nslookup hostname" to
516 intialize the resolver library before chroot'ing. On some systems this
517 reduces the number of files that must be copied into the chroot tree.
518 (Patch provided by Stephen Gildea)
519 - Fix a long-standing memory corruption bug that could cause
520 Privoxy to overwrite a single byte in memory it didn't explicitly
521 allocate (but that probably was allocated anyway due to bucket size).
522 - Send template-based CGI pages as HTTP/1.1 unless the client
524 - Let the first line in connection established responses
525 end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
526 - If no log file has been specified, disable logging instead of logging
528 - Don't block stderr when in daemon mode.
529 - Ignore missing zero-chunks when filtering chunk-encoded content.
530 Earlier Privoxy versions would buffer and then forward the content
531 unmodified which caused some browsers to simply show empty pages.
532 - Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
533 - The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
534 action isn't being used has been removed.
535 - Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
537 - Minor code clean-ups, filter and action file updates.
538 (Some of them reported by Davide Alberani, Markus Elfring,
539 Stefan Huehner and Adam Piggott)
541 *** Version 3.0.6 ***
543 - New content filters: no-ping, google, msn, yahoo and blogspot.
544 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
545 and hide-tor-exit-notation.
546 - The special header "X-Filter: No" now disables header filtering as well.
547 - Improved the filters img-reorder, js-annoyances, webbugs,
548 banners-by-size, banners-by-link and ie-exploits to make them

560 http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
561 following new or significantly improved actions (among many
564 content-type-overwrite{}
565 crunch-client-header{string}

575 hide-if-modified-since
576 hide-referrer{conditional-block}
577 overwrite-last-modified{}

605 - Further tightened security against malicious toggle-off links.
606 - Excluded text/plain MIME types from filtering. This fixes a
607 couple of client-crashing, download corruption and
608 Privoxy performance issues, whose root cause lies in
609 web servers labelling content of unknown type as text/plain.
610 - Assorted fixes for POSIX compliance, signal handling, graceful
611 termination, compiler warnings, OSX support, Win32 systray,
612 error logging, hostname wildcards, correct detection of NetBSD.
613 - Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs

631 html-annoyances, content-cookies and fun filters
632 - Replaced filter "popups" by choice between two modes:
633 - "unsolicited-popups" tries to catch only the unsolicited ones

635 - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
636 - New filter "jumping-windows" that prevents windows from resizing
637 and moving themselves

642 - Improved cookie logging
643 - Rewrote make install target. Added uninstall and install-strip

778 *** Version 2.9.3 pre-Alpha Changes ***
780 - Amiga support (completely untested by me - I don't have an Amiga)
781 - "tinygif 3" support (redirects blocked images to a specified URL, so
782 the browser doesn't have to load and cache many copies of the same
784 - one case where there were both local and global "referrer" variables
785 (yuck!) clarified by renaming the local one to "refer".
786 - Fixed some places where close() was used instead of close_socket().
787 Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
788 - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
789 FORCE_LOAD_PREFIX. Needs fixing properly.
790 - Most URLs hardcoded into Junkbuster were changed to go through a script
791 e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
792 The only other URLs left are the GNU GPL:
793 http://www.fsf.org/copyleft/gpl.html
795 http://ijbswa.sourceforge.net/
796 ... and various URLs which will be intercepted by Junkbuster anyway.
797 TODO: Still need to do something with the URLs in Junkbuster Corp's
798 copyright/trademark notice on the bottom of the show-proxy-args page.
799 - PCRE or GNU Regex is now a #define option.
802 *** Version 2.9.2 pre-Alpha Changes ***
804 - Andreas applied the latest version of the FORCE patch.
807 *** Version 2.9.1 pre-Alpha Changes ***
809 - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
810 (BTW: I think FORCE is precise enough, since loading remote
811 data is the whole purpose of a proxy..)
812 - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
813 is more elegant and looks like a hostname in the URL, it doesn't
814 make clear to the inexperienced user that the proxy is bypassed. It
815 also has a higher name collision risk.
816 - Filled in the function header templates for my functions in
817 parsers.c (again). They obviously got lost in our current
819 - Cut the credit for the §-referrer-option from the config file,
820 that Stefan had placed there.
821 - Improved the re_filterfile
824 *** Version 2.9.0 pre-Alpha Changes ***
826 - Now use PCRE, not GNU REGEX. I have not yet had chance to check the
827 syntax of the block/image/cookie file to ensure that they match what
828 is expected - however they seem to work.
829 - Replaced "configure" script with one generated by "autoconf". Also
830 use a header "config.h" (was ijbconfig.h in my previous release) for
831 the #defines. "config.h" is now generated with "autoheader" from
832 "acconfig.h" and "configure.in". (Note that to install you do not
833 need autoconf or autoheader - just run "./configure".)
834 To see command-line options, run "./configure --help".
835 This is my first ever autoconf script, so it has some rough edges
836 (how PCRE is handled is the roughest).
837 - Error logging code replaced with new module errlog.c, based on the
838 one from JunkbusterMT (but with the threading code removed).
839 - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
840 apply all of these, since I had already independently done conditional
841 popup file, conditional image file, and integration of popup code.
842 - ACL, Jar and trust files conditionally compiled.
843 - New source file headers.
844 - Various cosmetic changes. (But I have not consistently ordered the
845 config files - I think that's worthwhile, but it's 1am and I want to
847 - RCS tags on .h files.
848 - RCS tags are const char[] rather than const char *. (Saves 4 bytes
850 - VC++ project files renamed to vc_junkbuster.*.
851 - show-proxy-args now shows status of all conditionals, not just REGEX
852 - Various functions moved around. Most notably all the system-specific
853 sockets code which was spread between jcc.c, bind.c, and connect.c,
854 has been moved to "jbsockets.c". The non-system-specific code from
855 connect.c and socks4.c has been movet to "gateway.c". Also, the
856 config file loader and the global variables it writes to have been
857 moved to "loadcfg.c". (Maybe this should go into loaders.c?)
858 And candidate for the "worst filename ever" award is "miscutil.c",
859 which contains, well, miscellaneous utility functions like zalloc.
860 (Suggestions for a better name for this file are welcome!)
861 - Loaders now use a common function to read a line and skip comments,
862 and this function also stores the proxy_args.
863 - Added ./junkbuster --help (Not for Win32 GUI)
864 - Added ./junkbuster --version (Not for Win32 GUI)
865 - Win32 resources are now all marked as "U.S. English", rather than
866 being a mix of "U.S. English", "U.K. English" and "Irish English".
867 - Version number changes to 2.9.0
