The client - is then supposed to silently retry the request without bothering - the user. This should significantly reduce the frequency of the - "No server or forwarder data received" error message many users - reported. -- More reliable detection of prematurely closed client sockets - with keep-alive enabled. -- FEATURE_CONNECTION_KEEP_ALIVE is decoupled from - FEATURE_CONNECTION_SHARING and now available on - all platforms. -- Improved handling of POST requests on reused connections. - Should fix problems with stalled connections after submitting - form data with some browser configurations. -- Fixed various latency calculation issues. -- Allows the client to pass NTLM authentication requests to a - forwarding proxy. This was already assumed and hinted to work - in 3.0.13 beta but actually didn't. Now it's confirmed to work - with IE, Firefox and Chrome. - Thanks to Francois Botha and Wan-Teh Chang -- Fixed a calculation problem if receiving the server headers - takes more than two reads, that could cause Privoxy to terminate - the connection prematurely. Reported by Oliver. -- Compiles again on platforms such as OpenBSD and systems - using earlier glibc version that don't support AI_ADDRCONFIG. - Anonymously submitted in #2872591. -- A bunch of MS VC project files and Suse and Redhat RPM spec - files have been removed as they were no longer maintained for - quite some time. -- Overly long action lines are properly rejected with a proper - error message. Previously they would be either rejected as - invalid or cause a core dump through abort(). -- Already timed-out connections are no longer temporarily remembered. - They weren't reused anyway, but wasted a socket slot. -- len refers to the number of bytes actually read which might - differ from the ones received. Adjust log messages accordingly. -- The optional JavaScript on the CGI page uses encodeURIComponent() - instead of escape() which doesn't encode all characters that matter. - Anonymously reported in #2832722. -- Fix gcc45 warnings in decompress_iob(). -- Various log message improvements. -- Privoxy-Regression-Test supports redirect tests. -- Privoxy-Log-Parser can gather some connection statistics. - -*** Version 3.0.14 beta *** - -- The latency is taken into account when evaluating whether or not to - reuse a connection. This should significantly reduce the number of - connections problems several users reported. -- If the server doesn't specify how long the connection stays alive, - Privoxy errs on the safe side of caution and assumes it's only a second. -- The error pages for connection timeouts or missing server data use a - Last-Modified date in the past. Retry attempts are detected and Privoxy - removes the If-Modified-Since header to prevent the server from responding - with status code 304 in which case the client would reuse the error message. -- Setting keep-alive-timeout to 0 disables keep-alive support. Previously - Privoxy would claim to allow persistence but not reuse the connection. -- Pipelined requests are less likely to be mistaken for the request - body of the previous request. Note that Privoxy still has no real - pipeline support and will either serialize pipelined requests or - drop them in which case the client has to resent them. -- Fixed a crash on some Windows versions when header randomization - is enabled and the date couldn't be parsed. -- Privoxy's keep-alive timeout for the current connection is reduced - to the one specified in the client's Keep-Alive header. -- For HTTP/1.1 requests, Privoxy implies keep-alive support by not - setting any Connection header instead of using 'Connection: keep-alive'. -- If the socket isn't reusable, Privoxy doesn't temporarily waste - a socket slot to remember the connection. -- If keep-alive support is disabled but compiled in, the client's - Keep-Alive header is removed. -- Fixed a bug on mingw32 where downloading large files failed if - keep-alive support was enabled. -- Fixed a bug that (at least theoretically) could cause log - timestamps to be occasionally off by about a second. -- No Proxy-Connection header if added if there already is one. -- The configure script respects the $PATH variable when searching - for groups and id. - -*** Version 3.0.13 beta *** - -- Added IPv6 support. Thanks to Petr Pisar who not only provided - the initial patch but also helped a lot with the integration. -- Added client-side keep-alive support. -- The connection sharing code is only used if the connection-sharing - option is enabled. -- The max-client-connections option has been added to restrict - the number of client connections below a value enforced by - the operating system. -- Fixed a regression reintroduced in 3.0.12 that could cause - crashes on mingw32 if header date randomization was enabled. -- Compressed content with extra fields couldn't be decompressed - and would get passed to the client unfiltered. This problem - has only be detected through statical analysis with clang as - nobody seems to be using extra fields anyway. -- If the server resets the Connection after sending only the headers - Privoxy forwards what it got to the client. Previously Privoxy - would deliver an error message instead. -- Error messages in case of connection timeouts use the right - HTTP status code. -- If spawning a child to handle a request fails, the client - gets an error message and Privoxy continues to listen for - new requests right away. -- The error messages in case of server-connection timeouts or - prematurely closed server connections are now template-based. -- If zlib support isn't compiled in, Privoxy no longer tries to - filter compressed content unless explicitly asked to do so. -- In case of connections that are denied based on ACL directives, - the memory used for the client IP is no longer leaked. -- Fixed another small memory leak if the client request times out - while waiting for client headers other than the request line. -- The client socket is kept open until the server socket has - been marked as unused. This should increase the chances that - the still-open connection will be reused for the client's next - request to the same destination. Note that this only matters - if connection-sharing is enabled. -- A TODO list has been added to the source tarballs to give potential - volunteers a better idea of what the current goals are. +*** Version 3.0.23 stable *** + +- Bug fixes: + - Fixed a DoS issue in case of client requests with incorrect + chunk-encoded body. When compiled with assertions enabled + (the default) they could previously cause Privoxy to abort(). + Reported by Matthew Daley. + - Fixed multiple segmentation faults and memory leaks in the + pcrs code. This fix also increases the chances that an invalid + pcrs command is rejected as such. Previously some invalid commands + would be loaded without error. Note that Privoxy's pcrs sources + (action and filter files) are considered trustworthy input and + should not be writable by untrusted third-parties. + - Fixed an 'invalid read' bug which could at least theoretically + cause Privoxy to crash. So far, no crashes have been observed. + - Compiles with --disable-force again. Reported by Kay Raven. + - Client requests with body that can't be delivered no longer + cause pipelined requests behind them to be rejected as invalid. + Reported by Basil Hussain. + +- General improvements: + - If a pcrs command is rejected as invalid, Privoxy now logs + the cause of the problem as text. Previously the pcrs error + code was logged. + - The tests are less likely to cause false positives. + +- Action file improvements: + - '.sify.com/' is no longer blocked. Apparently it is not actually + a pure tracking site (anymore?). Reported by Andrew on ijbswa-users@. + - Unblock banners on .amnesty.de/ which aren't ads. + +- Documentation improvements: + - The 'Would you like to donate?' section now also contains + a "Paypal" address. + - The list of supported operating systems has been updated. + - The existence of the SF support and feature trackers has been + deemphasized because they have been broken for months. + Most of the time the mailing lists still work. + - The claim that default.action updates are sometimes released + on their own has been removed. It hasn't happened in years. + - Explicitly mention that Tor's port may deviate from the default + when using a bundle.
