If you only care about crunched + requests, simply replace "debug 1" with "debug 1024". +- A "clear log" view option was added to the mingw32 version + to clear out all of the lines in the Privoxy log window. + Based on a patch submitted by T Ford. +- The mingw32 version uses "critical sections" now which + prevents log message corruption under load. As a side effect, + the "no thread-safe PRNG" warning could be removed as well. +- Support for remote toggling is controlled by the configure + option --disable-toggle only. In previous versions it also + depended on the action editor and thus configuring with the + --disable-editor option would disable remote toggling support + as well. +- The hide-forwarded-for-headers action has been replaced with + the change-x-forwarded-for{} action which can also be used to + add X-Forwarded-For headers. The latter functionality already + existed in Privoxy versions prior to 3.0.7 but has been removed + as it was often used unintentionally (by not using the + hide-forwarded-for-headers action). + +*** Version 3.0.10 *** + +- Ordinary configuration file changes no longer cause program + termination on OS/2 if the name of the logfile hasn't been + changed as well. This regression probably crept in with the + logging improvements in 3.0.7. Reported by Maynard. +- The img-reorder filter is less likely to mess up JavaScript code in + img tags. Problem and solution reported by Glenn Washburn in #2014552. +- The source tar ball now includes Privoxy-Log-Parser, + a syntax-highlighter for Privoxy logs. For fancy screenshots see: + http://www.fabiankeil.de/sourcecode/privoxy-log-parser/ + Documentation is available through perldoc(1). + +*** Version 3.0.9 Beta *** + +- Added SOCKS5 support (with address resolution done by + the SOCKS5 server). Patch provided by Eric M. Hopper. +- The "blocked" CGI pages include a block reason that was + provided as argument to the last-applying block action. +- If enable-edit-actions is disabled (the default since 3.0.7 beta) + the show-status page hides the edit buttons and explains why. + Previously the user would get the "this feature has been disabled" + message after using the edit button. +- Forbidden CONNECT requests are treated like blocks by default. + The now-pointless treat-forbidden-connects-like-blocks action + has been removed. +- Not enabling limit-connect now allows CONNECT requests to all ports. + In previous versions it would only allow CONNECT requests to port 443. + Use +limit-connect{443} if you think you need the old default behaviour. +- The CGI editor gets turned off after three edit requests with invalid + file modification timestamps. This makes life harder for attackers + who can leverage browser bugs to send fake Referers and intend to + brute-force edit URLs. +- Action settings for multiple patterns in the same section are + shared in memory. As a result these sections take up less space + (and are loaded slightly faster). Problem reported by Franz Schwartau. +- Linear white space in HTTP headers will be normalized to single + spaces before parsing the header's content, headers split across + multiple lines get merged first. This should prevent problems like: + * letting the session-cookies-only action slip + some Cookies through unmodified, + * only suppressing the first line of a header, + thus creating an invalid one, and + * to incorrectly block headers with valid timestamps + that weren't properly recognized. + Headers that could trigger these problems are unlikely to appear + in "normal" web traffic, but could be intentionally generated to + fool some of Privoxy's header parsers. +- Host information is gathered outside the main thread so it's less + likely to delay other incoming connections if the host is misconfigured. +- New config option "hostname" to use a hostname other than + the one returned by the operating system. Useful to speed-up responses + for CGI requests on misconfigured systems. Requested by Max Khon. +- The CGI editor supports the "disable all filters of this type" + directives "-client-header-filter", "-server-header-filter", + "-client-header-tagger" and "-server-header-tagger". +- Fixed false-positives with the link-by-url filter and URLs that + contain the pattern "/jump/". +- The less-download-windows filter no longer messes + "Content-Type: application/x-shockwave-flash" headers up. +- In the show-url-info page's "Final results" section active and + inactive actions are listed separately. Patch provided by Lee. +- The GNUmakefile supports the DESTDIR variable. Patch for + the install target submitted by Radoslaw Zielinski. +- Embedding the content of configuration files in the show-status + page is significantly faster now. For a largish action file (1 MB) + a speedup of about 2450 times has been measured. This is mostly + interesting if you are using large action files or regularly use + Privoxy-Regression-Test while running Privoxy through Valgrind, + for stock configuration files it doesn't really matter. +- If zlib support is unavailable and there are content + filters active but the prevent-compression action is disabled, + the show-url-info page includes a warning that compression + might prevent filtering. +- The show-url-info page provides an OpenSearch Description that + allows to access the page through browser search plugins. +- Custom client-header filters that rewrite the request line + incorrectly no longer cause Privoxy to crash. Reported by din_a4. +- The obsolete kill-popups action has been removed as the + PCRS-based popup filters can do the same and are slightly + less unreliable. +- The inspect-jpegs action has been removed. +- The send-wafer and send-vanilla-wafer actions have been removed. + They weren't particular useful and their behaviour could be emulated + with add-header anyway. +- Privoxy-Regression-Test has been significantly improved. +- Most sections in the default.action file contain tests for + Privoxy-Regression-Test to verify that they are working as intended. +- Parts of Privoxy have been refactored to increase maintainability. +- Building with zlib (if available) is done by default. + +*** Version 3.0.8 *** + +- Fixed a small memory leak when listen-address only specifies the port. +- The source tar balls now include Privoxy-Regression-Test which + (upon other things) can be used to automatically detect some + packaging problems. Packagers are welcome to give it a try. +- Reverted a change in 3.0.7 that caused path patterns to be checked + even if the host pattern match already failed. While this doesn't + noticeable affect the performance, it makes it less likely to run + out of stack space with overly-complex path patterns the user might + have added. +- Updated the msn, yahoo and google filters to work as advertised again. +- The warning message shown by the show-status CGI page is easier to + understand. Previously it wasn't clear that the error message + is shown below the invalid directive. (Reported by Lee) +- When regenerating Content-Disposition headers the more common + spelling is used for the name. Previously it was written without caps. +- Less confusing log message if the content type isn't overwritten + because force-text-type wasn't used but the old type doesn't look + like content that would be filtered normally. +- Better log messages if the user tries to execute filters that + don't exist. +- Treat the non-standard Request-Range headers like standard range + headers and suppress them if content filtering is enabled. +- Prevent the log messages for CONNECT requests to unacceptable + ports from printing the limit-connect argument as [null] if + limit-connect hasn't been explicitly enabled. +- Don't disable the mingw32 log window if the logfile directive + isn't used. While it was an intentional change in 3.0.7 at least + one user perceived it as a regression and the same effect can + be achieved by disabling all debug directives. +- Fixed two minor problems related to the win32 build process: a css + file was not being in the installer and the trustfile comment in the + config.txt referenced a nonexisting file +- Minor documentation fixes. + +*** Version 3.0.7 Beta *** + +- Added zlib support to filter content with gzip and deflate + encoding. (Patch provided by Wil Mahan) +- Dedicated filters and actions are used for header filtering. + "filter-client-headers" and "filter-client-headers" are no longer + supported, use server-header-filter{} and client-header-filter{} + instead. +- Tags can be used to change actions based on HTTP headers. +- New server-header filter: less-download-windows. +- New client-header taggers: css-requests, image-requests, + client-ip-address, http-method, allow-post, complete-url, + user-agent and privoxy-control. +- New server-header taggers: content-type and privoxy-control. +- The forward-override{} action allows to change the forwarding + settings through the action files, for example based on client + headers like the User-Agent, or the request origin. +- Socks errors are no longer handled by the CGI page for + DNS resolution failures. +- CGI pages use favicons to signal whether they are error + or control pages. This is useful if you rely heavily on + browser tabs. +- The show-url-info CGI page shows the forwarding settings. +- "Crunch!" log messages (used when Privoxy answers requests + by itself) now also contain the reason. +- Allow to rewrite the request destination behind the client's back. +- Fix socks requests on big-endian platforms. Patch provided by Song Weijia. +- Fixes possible deadlocks and crashes on OpenBSD. + Patch provided by Ralf Horstmann. +- The CGI action editor allows to edit actionfiles with previously + forbidden characters like dots. +- New trust entries are saved with a comment that contains the + trusted referring URL (Suggested by Daniel Griscom). +- Filter descriptions are HTML encoded automatically. +- New config option "split-large-forms" to work + around a browser bug that caused IE6 and IE7 to ignore + the Submit button on the edit-actions-for-url CGI page. +- New config option "allow-cgi-request-crunching" to allow + requests for Privoxy's CGI pages to be blocked, redirected + or (un)trusted like ordinary requests. +- Empty filter files no longer interrupt the filtering process + prematurely and are correctly listed on the show-status CGI page. +- New config option "accept-intercepted-requests" to combine + Privoxy with any packet filter to build an intercepting proxy + for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set). +- fast-redirects{} catch redirects to https URLs as well. +- redirect{s@foo@bar@} can be used to redirect to a rewritten + version of the original URL. +- Trap unsupported gopher proxy requests. +- Fixed a bug in the User Manual delivery on Windows + (mingw32 only). Images now show up correctly and HTML + pages are no longer padded with garbage data. +- Fixed several minor memory leaks, most of them discovered with Valgrind. +- Only unlink the pidfile if it's actually used. +- Retries after connection problems with forced requests + aren't blocked again. +- On Unix SIGABRT causes a core dump as expected and is no + longer treated as normal shutdown signal. +- The "access denied" CGI page is more descriptive and + allows retries to circumvent the referrer check. +- Updated PCRS to handle unexpected PCRE errors properly. + Fixed crashes that could occur if Privoxy was build + with external PCRE versions newer than Privoxy's internal + one. (Reported by Chung-chieh Shan) +- Fixed crashes with null bytes in PCRS replacement strings + (Patch provided by Felix Gröbert). +- Fixed crashes with header time randomization on mingw32. +- The CGI style sheet is no longer delivered if the referring + page isn't a Privoxy CGI page. This prevents a JavaScript-based + Privoxy detection "attack". Note that detecting Privoxy is + still possible through other ways and Privoxy was never intended + to be invisible anyway. +- Added support for AmigaOS 4, fixed build for AmigaOS 3.x. +- The show-url-info CGI page displays a warning if Privoxy + is currently toggled off. +- The show-status CGI page suppresses the edit button + for action files if Privoxy has no write access. +- Most CGI error pages react properly to HEAD requests. +- Requests with RFC 3253 HTTP methods (used by Subversion) + are accepted. (Patch provided by Petr Kadlec) +- New config option "templdir" to change the location + of the CGI templates to make sure customized templates + aren't "updated". +- Better handling of "HTTP/1.1 100 Continue" responses. +- The background of the PNG pattern is transparent. +- Fixed XML syntax errors caused by banners-by-size and banners-by-url. +- Fixed crashes and possible action file corruptions + when lines containing hashes are written through the CGI editor. +- Supports dynamic filters which can contain variables. +- Supports tags to change the actions based on client or server headers. +- Incorrect actions are logged before program termination. +- The "actionsfile" syntax in the configuration file is consistent + with the rest of the configuration options and requires the + whole file name. This is an incompatible change, if you use + an old configuration file you might have to append ".action" + to your "actionsfile" directives. +- With the configuration file option "enforce-blocks" the + "go there anyway" mechanism can be disabled without recompiling + Privoxy. +- More precise error messages in case of incorrect acl syntax. +- Logs a warning if filtering is enabled but impossible due + to lack of zlib support or use of the prevent-compression action. +- Less noisy handling of Cookie:" and "Connection:" headers. +- Improved error messages in case of connection problems. +- Fix a command-line-parsing bug that was introduced before 3.0.5 + beta and caused Privoxy to treat the last argument as configuration + file if no configuration file was specified. +- Treat unknown command line options as fatal errors instead + of silently ignoring them. +- Use string functions with length checks more often. +- Don't log CONNECT requests twice. +- Allow to log the source address for ACL-related connection drops. +- Don't ignore applying filters if the server didn't + specify a Content-Type. Bug reported by Amuro Namie. +- Rejected CONNECT requests are logged with log level info + (enabled by default) and the reason for the block. +- New command line option "--pre-chroot-nslookup hostname" to + intialize the resolver library before chroot'ing. On some systems this + reduces the number of files that must be copied into the chroot tree. + (Patch provided by Stephen Gildea) +- Fix a long-standing memory corruption bug that could cause + Privoxy to overwrite a single byte in memory it didn't explicitly + allocate (but that probably was allocated anyway due to bucket size). +- Send template-based CGI pages as HTTP/1.1 unless the client + asked for HTTP/1.0. +- Let the first line in connection established responses + end in \r\n as required by RFC1945. Reported by Bert van Leeuwen. +- If no log file has been specified, disable logging instead of logging + to stderr. +- Don't block stderr when in daemon mode. +- Ignore missing zero-chunks when filtering chunk-encoded content. + Earlier Privoxy versions would buffer and then forward the content + unmodified which caused some browsers to simply show empty pages. +- Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB. +- The code to add X-Forwarded-For headers when the hide-forwarded-for-headers + action isn't being used has been removed. +- Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE. + Reported by Lee. +- Minor code clean-ups, filter and action file updates. + (Some of them reported by Davide Alberani, Markus Elfring, + Stefan Huehner and Adam Piggott) + +*** Version 3.0.6 *** + +- New content filters: no-ping, google, msn, yahoo and blogspot. +- New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html + and hide-tor-exit-notation. +- The special header "X-Filter: No" now disables header filtering as well. +- Improved the filters img-reorder, js-annoyances, webbugs, + banners-by-size, banners-by-link and ie-exploits to make them + less likely to break anything. +- Removed outdated URL patterns in default.action and added new ones. +- Added redirection from http://p.p/user-manual to http://p.p/user-manual/ +- Changed webinterface default values for hide-user-agent, hide-referrer + and set-image-blocker. + +*** Version 3.0.5 Beta *** + +- Windows version can be installed/started as a service. +- Windows icon stays blue when Privoxy is idle, green when busy. +- Integrated Fabian Keil's extensive patch. See: + http://www.fabiankeil.de/sourcecode/privoxy/. Includes the + following new or significantly improved actions (among many + other improvements): + + content-type-overwrite{} + crunch-client-header{string} + crunch-if-none-match + crunch-server-header{string} + fast-redirects{check-decoded-url} + filter-client-headers + filter-server-headers + force-text-mode + handle-as-empty-document + hide-accept-language{} + hide-content-disposition{} + hide-if-modified-since + hide-referrer{conditional-block} + overwrite-last-modified{} + redirect{URL} + treat-forbidden-connects-like-blocks + +- Standard-compliant clients are prevented from displaying cached + copies of Privoxy's error messages after the cause of the problem + has gone. +- Improved DNS error handling. - Multiple filter files can now be specified in config. - Added jpeg filtering to defend against MS jpeg vulnerability MS04-028 + with the new inspect-jpegs action. - Removed the "arbitrary" 1000 filter limit - addresses tracker #911950 - Thanks to Jindrich Makovicka for a race condition fix for the log file. The race condition remains for non-pthread implementations. - Reference patch #1175720. + Reference patch #1175720.
