The most prominent new feature is support for "keep-alive" -connection. There are many small improvements. + Announcing Privoxy 3.0.29 stable +-------------------------------------------------------------------- -See http://www.privoxy.org/3.0.11/user-manual/whatsnew.html for details. +Privoxy 3.0.29 stable fixes a couple of memory leaks and introduces +https inspection which allows to filter encrypted requests and +responses. -------------------------------------------------------------------- -ChangeLog for Privoxy +ChangeLog for Privoxy 3.0.29 -------------------------------------------------------------------- -*** Version 3.0.11 *** - -- On most platforms, outgoing connections can be kept alive and - reused if the server supports it. Whether or not this improves - things depends on the connection. -- When dropping privileges, membership in supplementary groups - is given up as well. Not doing that can lead to Privoxy running - with more rights than necessary and violates the principle of - least privilege. Users of the --user option are advised to update. - Thanks to Matthias Drochner for reporting the problem, - providing the initial patch and testing the final version. -- Passing invalid users or groups with the --user option - didn't lead to program exit. Regression introduced in 3.0.7. -- The match all section has been moved from default.action - to a new file called match-all.action. As a result the - default.action no longer needs to be touched by the user - and can be safely overwritten by updates. -- The standard.action file has been removed. Its content - is now part of the default.action file. -- In some situations the logged content length was slightly too low. -- Crunched requests are logged with their own log level. - If you used "debug 1" in the past, you'll probably want - to additionally enable "debug 1024", otherwise only passed - requests will be logged. If you only care about crunched - requests, simply replace "debug 1" with "debug 1024". -- The crunch reason has been moved to the beginning of the - crunch message. For HTTP URLs, the protocol is logged as well. -- Log messages are shortened by not printing the thread id - on its own (as opposed to putting it inside "Privoxy()". -- The config option socket-timeout has been added to control - the time Privoxy waits for data to arrive on a socket. -- 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. -- Requests with invalid HTTP versions are rejected. -- The template symbol @date@ can be used to include a date(1)-like - time string. Initial patch submitted by Endre Szabo. -- Responses from shoutcast servers are accepted again. - Problem reported and fix suggested by Stefan. -- 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). -- 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. -- The mingw32 version's task bar icon is crossed out and - the color changed to gray if Privoxy is toggled off. +- Security/Reliability: + - Fixed memory leaks when a response is buffered and the buffer + limit is reached or Privoxy is running out of memory. + Commits bbd53f1010b and 4490d451f9b.

OVE-20201118-0008. + +- General improvements: + - Added experimental https inspection support which allows to filter + https traffic. To enable it, install MbedTLS and configure with + --with-mbedtls, or install OpenSSL or LibreSSL and configure + with --with-openssl. + Afterwards configure the directives in section 7 of the + config file and enable the +https-inspection action. + Initial MbedTLS-based code contributed by Vaclav Svec, + initial OpenSSL support contributed by Maxim Antonov. + With help from Nedzad Hrnjica and Ho+ Ho+ Ho+. + Integration and improvements sponsored by Robert Klemme. + - pcrs: Request JIT compilation if it's supported and + the filter isn't dynamic. This can speed up filtering. + - Added support for Brotli decompression. + Sponsored by: Robert Klemme + - Added FEATURE_EXTENDED_STATISTICS to gather statistics for + block reasons and filter executions. To enable it, configure + with --enable-extended-statistics and visit + http://config.privoxy.org/show-status. + Sponsored by: Robert Klemme + - Use the IP_FREEBIND socket option, if defined. This allows + Privoxy to bind to not-yet assigned IP addresses which is + useful in failover environments. + Patch by Sam Varshavchik. + - Allow to use extended host patterns and vanilla host patterns + at the same time by prefixing extended host patterns with + "PCRE-HOST-PATTERN:". To enable this, configure with + --enable-pcre-host-patterns. + Sponsored by: Robert Klemme + - Added "Cross-origin resource sharing" (CORS) support. + This allows to access Privoxy's CGI interface via JavaScript from + another domain (white-listed with the new cors-allowed-origin directive). + Based on a patch by Nedzad Hrnjica. + Sponsored by: Robert Klemme. + - Add SOCKS5 username/password support. + Based on a patch by Sam, improved by Ivan Romanov. + Closes Patch#141 and solves TODO#105. + - Bump the maximum number of action and filter files + to 100 each. + Sponsored by: Robert Klemme + - Fixed handling of filters with "split-large-forms 1" + when using the CGI editor. + Reported by withoutname in #921. + - Better detect a mismatch of connection details when + figuring out whether or not a connection can be reused. + - Don't send a "Connection failure" message instead of the + "DNS failure" message. + Sponsored by: Robert Klemme + - Let LOG_LEVEL_REQUEST log all requests. Previously unencrypted + requests were only logged with LOG_LEVEL_REQUEST when they weren't + crunched (in which case they were logged with LOG_LEVEL_CRUNCH). + This was documented behaviour, but logging all requests seems more useful. + - Fixed locking around localtime() and gmtime(). + - Removed OS/2 support. We haven't provided OS/2 packages in years, + it complicated the code and it depended on a fallback snprintf() + implementation which is GPLv2 only. + - Remove the fallback snprintf() implementation + Now that OS/2 support is gone we no longer need it. + - Fixed a bunch of format specifiers log messages. + - Added a missing apostrophe in the 'More Privoxy' menu. + - Explicitly prevent use of FEATURE_CONNECTION_SHARING + without FEATURE_CONNECTION_KEEP_ALIVE. It makes no sense + and does not compile anyway. + Sponsored by: Robert Klemme + - Fix build without FEATURE_CONNECTION_KEEP_ALIVE. + Sponsored by: Robert Klemme + - Downgrade the 'Graceful termination requested' message + to LOG_LEVEL_INFO as it isn't an error. + Sponsored by: Robert Klemme + - decompress_iob(): Downgrade the no-content message to LOG_LEVEL_RE_FILTER + While at it, fix a typo in a comment. + Sponsored by: Robert Klemme + - Fixed a couple of cppcheck warnings. + - Rename LOG_LEVEL_GPC to LOG_LEVEL_REQUEST. + Only the shadow knows what "GPC" is supposed to stand for. + - Remove SourceForge references in copyright headers. + - Upgrade a bunch of links to the homepage to https://. + - Add 'no-brotli-accepted' filter which prevents the + use of Brotli compression. + - Changed license for pcrs to GPLv2+ after getting the + permission from Andreas. This allows to redistribute + Privoxy under the GPLv3 which is required when linking + to future mbedTLS versions which are expected to be + licensed under the Apache 2.0 license only. + - Updated a bunch of tests that have to expect status code 403 + now after r1.168/070e904afa5. + - Lowercase the host name in the request line. + - Only set SOURCE_DATE_EPOCH if it's not already set so + distributions can overwrite it through the environment. + +- Documentation changes: + - Explain that Privoxy has to be distributed under the + GPLv3 (or later) when linked with an MbedTLS version + that is licensed under the Apache 2.0 license. + - Import the GNU GPLv3 and include it the user manual. + - Clarify FEATURE_FORCE_LOAD's description. It allows to bypass + blocking not filtering and only does it if blocks aren't enforced. + Reported by: Robert Klemme + - FAQ: Remove Zwiebelfreunde e.V. from the list of fiduciary sponsors + As of 2021 they no longer handle donations for foreign organisations + due to lack of resources. + - FAQ: Remove an obsolete comment with a link to the long-gone PDF manual. + - FAQ: Add a link to the TODO list. + - FAQ: Change the sponsor amounts to USD slightly rounding the + converted amounts up to get simple numbers. + Receiving USD is apparently easier for SPI and SPI is + preferred by sponsors as they can send invoices. + - Advertise the client-tags CGI page in the user manual. + - Stop advertising the show-version CGI page which no longer exists. + - Add yet another reason why +prevent-compression may cause problems. + - Don't claim that contributors need ssh. It's only needed for committers. + - Replace obsolete CVS instructions with Git instructions. + - Remove an obsolete comment + +- Config file changes: + - Change the suggested default-server-timeout to 5 to match the + suggested keep-alive-timeout. Otherwise using the defaults would + result in Privoxy reducing the default-server-timeout and logging + an error message. + Sponsored by: Robert Klemme + - Update the 'debug 1' description. + - Add a missing 'client-specific-tag' directive. + - Comment out trusted-cgi-referer pointing to example.org. + +- Action file improvements: + - Block requests to /(.*/)?piwik\.php + - Block requests to .connectaserver.de/ + - Block requests to pixel.inforsea.com/ + - Block requests to t.vi-serve.com/ + - Block requests to .ioam.de/ + - Block requests to t.9gag.com/img.gif + - Block requests to .pixel.parsely.com/ as image + - Block requests to pixel.wp.com/ + - Disable fast-redirects for .librarything.com/ + - Disable fast-redirects for issue.freebsdfoundation.org/ + - Disable fast-redirects for .twitter.com/.*origin=http + - Unblock belco24.de/ + - Add fast-redirects exception for .wikipedia.org/ + - Add fast-redirects exception for oss-fuzz.com/ + - Disable fast-redirects for .consensu.org/delivery/pixel\.php + and block the requests as image instead + - Unblock .adbinstaller.com/ + Reported by lvm in #942. + - Unblock .adbshell.com + Reported by lvm in #942. + - Unblock .tagesschau.de/ + - Disable fast-redirects for collector.githubapp.com/ + and block requests to it as image instead + - Unblock 'ada*.' + - Add fast-redirects{} exception for sourcepoint.vice.com/ + - Unblock adaway.org/ + Reported by DRS David Soft in AF#945. + - Change two block reasons that previously were the same. + Sponsored by: Robert Klemme + - Added a +delay-response{} test. + - Updated the location of the development version + of default.action.master. + +- Privoxy-Log-Parser: + - Added a --keep-date option to keep the date in highlighted messages. + - Highlight new log messages. + - Make gather_loglevel_clf_stats() more tolerant. While at it, + count all CLF messages as requests, even if the request is invalid. + - Only show HTTP version distribution if at least one version has been detected. + - Only show crunch statistics if crunches were detected. + - Warn if the request counts differ. + - Generate statistics if the log only contains LOG_LEVEL_CLF messages + so it can be used with vanilla webserver logs. + Previously Privoxy-specific "Request:" messages were required. + - Align the client-HTTP-version distribution like other distributions + - Bump version to 0.9.1 + - Include status code distribution in the stats. + - Let the statistics include the size of the content Privoxy + transferred excluding HTTP headers. + - Get with the program and expect all requests to be logged with LOG_LEVEL_REQUEST. + It's no longer necessary to count both LOG_LEVEL_REQUEST and + LOG_LEVEL_CRUNCH messages to get the total number of requests. + - Leverage the LOG_LEVEL_CLF message to gather statistics that where + previously taken from LOG_LEVEL_HEADER lines. This results in less + confusing results if https inspection is enabled in which case there + are two LOG_LEVEL_HEADER lines with request lines. + Sponsored by: Robert Klemme + - Properly highlight the filter results message. Previously a brace got lost. + - Prefer the number of CLF lines to get the total number of requests + as it works with older Privoxy versions as well. + +- Privoxy-Regression-Test: + - Turn curl's globbing mode off so we can allow more characters in URLs. + - Allow '[' and ']' in URLs. + - Include the action file when complaining about missing Sticky Actions. + - Fix a sentence in the documentation. + - Bump version to 0.7.1 + +- url-pattern-translator: + - Detect a couple of pattern prefixes case-insensitively. + Sponsored by: Robert Klemme + - Skip CLIENT-TAG patterns. + Sponsored by: Robert Klemme + - Skip patterns that have already been converted. + It should now be safe to "convert" a file multiple times. + Sponsored by: Robert Klemme + - Add the new 'PCRE-HOST-PATTERN:' prefix. + Sponsored by: Robert Klemme + ----------------------------------------------------------------- About Privoxy: ----------------------------------------------------------------- -Privoxy is a web proxy with advanced filtering capabilities for -protecting privacy, modifying web page data, managing cookies, -controlling access, and removing ads, banners, pop-ups and other -obnoxious Internet junk.
