Like the previous bug, this caused Privoxy - to wait for the end of the content until the server closed the connection. - Fixes #3022042 and #3025553, reported by a user with no visible name. - Most likely also fixes a bunch of other AJAX-related problem reports - that got closed in the past due to insufficient information and lack - of feedback. -- Fixed an ACL bug that made it impossible to build a blacklist. - Usually the ACL directives are used in a whitelist, which worked - as expected, but blacklisting is still useful for public proxies - where one only needs to deny known abusers access. -- Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the - network. This should make debugging various parsing issues a lot easier. -- The IPv6 code is enabled by default on Windows versions that support it. - Patch submitted by oCameLo in #2942729. -- In mingw32 versions, the user.filter file is reachable through the - GUI, just like default.filter is. Feature request 3040263. -- Added the configure option --enable-large-file-support to set a few - defines that are required by platforms like GNU/Linux to support files - larger then 2GB. Mainly interesting for users without proper logfile - management. -- Logging with "debug 16" no longer stops at the first nul byte which is - pretty useless. Non-printable characters are replaced with their hex value - so the result can't span multiple lines making parsing them harder then - necessary. -- Privoxy logs when reading an action, filter or trust file. -- Fixed incorrect regression test markup which caused a test in - 3.0.16 to fail while Privoxy itself was working correctly. - While Privoxy accepts hide-referer, too, the action name is actually - hide-referrer which is also the name used one the final results page, - where the test expected the alias. - -- CGI interface improvements: - - In finish_http_response(), continue to add the 'Connection: close' - header if the client connection will not be kept alive. - Anonymously pointed out in #2987454. - - Apostrophes in block messages no longer cause parse errors - when the blocked page is viewed with JavaScript enabled. - Reported by dg1727 in #3062296. - - Fix a bunch of anchors that used underscores instead of dashes. - - Allow to keep the client connection alive after crunching the previous request. - Already opened server connections can be kept alive, too. - - In cgi_show_url_info(), don't forget to prefix URLs that only contain - http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott. - - Show the 404 CGI page if cgi_send_user_manual() is called while - local user manual delivery is disabled. + +- 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.
