- Announcing Privoxy v.3.0.11
------------------------------------------------------------------
-
-3.0.11 is a stable release which includes many enhancements but no major
-new features. The most prominent new feature is "keep-alive" support for
-outgoing connections.
+ Announcing Privoxy v.3.0.20 beta
+--------------------------------------------------------------------
-See http://www.privoxy.org/3.0.11/user-manual/whatsnew.html for details.
+This is a beta release that introduces some new features and fixes a number of bugs, some of which are reasonably significant. One new feature (tolerate-pipelining) is enabled by default. See below for details.

ChangeLog for Privoxy
--------------------------------------------------------------------
-
-*** 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 printing the thread id on its
- own (as opposed to putting it inside the string "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.
+*** Version 3.0.20 Beta ***
+
+- Bug fixes:
+ - Client sockets are now properly shutdown and drained before being
+ closed. This fixes page truncation issues with clients that aggressively
+ pipeline data on platforms that otherwise discard already written data.
+ The issue mainly affected Opera users and was initially reported
+ by Kevin in #3464439, szotsaki provided additional information to track
+ down the cause.
+ - Fix latency calculation for shared connections (disabled by default).
+ It was broken since their introduction in 2009. The calculated latency
+ for most connections would be 0 in which case the timeout detection
+ failed to account for the real latency.
+ - Reject URLs with invalid port. Previously they were parsed incorrectly and
+ characters between the port number and the first slash were silently
+ dropped as shown by curl test 187.
+ - The default-server-timeout and socket-timeout directives accept 0 as
+ valid value.
+ - Fix a race condition on Windows that could cause Privoxy to become
+ unresponsive after toggling it on or off through the taskbar icon.
+ Reported by Tim H. in #3525694.
+ - Fix the compilation on Windows when configured without IPv6 support.
+ - Fix an assertion that could cause debug builds to abort() in case of
+ socks5 connection failures with "debug 2" enabled.
+ - Fix an assertion that could cause debug builds to abort() if a filter
+ contained nul bytes in the replacement text.
+
+- General improvements:
+ - Significantly improved keep-alive support for both client and server
+ connections.
+ - New debug log level 65536 which logs all actions that were applied to
+ the request.
+ - New directive client-header-order to forward client headers in a
+ different order than the one in which they arrived.
+ - New directive tolerate-pipelining to allow client-side pipelining.
+ If enabled (3.0.20 beta enables it by default), Privoxy will keep
+ pipelined client requests around to deal with them once the current
+ request has been served.
+ - New --config-test option to let Privoxy exit after checking whether or not
+ the configuration seems valid. The limitations noted in TODO #22 and #23
+ still apply. Based on a patch by Ramkumar Chinchani.
+ - New limit-cookie-lifetime{} action to let cookies expire before the end
+ of the session. Suggested by Rick Sykes in #1049575.
+ - Increase the hard-coded maximum number of actions and filter files from
+ 10 to 30 (each). It doesn't significantly affect Privoxy's memory usage
+ and recompiling wasn't an option for all Privoxy users that reached the
+ limit.
+ - Add support for chunk-encoded client request bodies. Previously
+ chunk-encoded request bodies weren't guaranteed to be forwarded correctly,
+ so this can also be considered a bug fix although chunk-encoded request
+ bodies aren't commonly used in the real world.
+ - Add support for Tor's optimistic-data SOCKS extension, which can reduce the
+ latency for requests on newly created connections. Currently only the
+ headers are sent optimistically and only if the client request has already
+ been read completely which rules out requests with large bodies.
+ - After preventing the client from pipelining, don't signal keep-alive
+ intentions. When looking at the response headers alone, it previously
+ wasn't obvious from the client's perspective that no additional responses
+ should be expected.
+ - Stop considering client sockets tainted after receving a request with body.
+ It hasn't been necessary for a while now and unnecessarily causes test
+ failures when using curl's test suite.
+ - Allow HTTP/1.0 clients to signal interest in keep-alive through the
+ Proxy-Connection header. While such client are rare in the real world, it
+ doesn't hurt and couple of curl tests rely on it.
+ - Only remove duplicated Content-Type headers when filters are enabled.
+ If they are not it doesn't cause ill effects and the user might not want it.
+ Downgrade the removal message to LOG_LEVEL_HEADER to clarify that it's not
+ an error in Privoxy and is unlikely to cause any problems in general.
+ Anonymously reported in #3599335.
+ - Set the socket option SO_LINGER for the client socket.
+ - Move several variable declarations to the beginning of their code block.
+ It's required when compiling with gcc 2.95 which is still used on some
+ platforms. Initial patch submitted by Simon South in #3564815.
+ - Optionally try to sanity-check strptime() results before trusting them.
+ Broken strptime() implementations have caused problems in the past and
+ the most recent offender seems to be FreeBSD's libc (standards/173421).
+ - When filtering is enabled, let Range headers pass if the range starts at
+ the beginning. This should work around (or at least reduce ) the video
+ playback issues with various Apple clients as reported by Duc in #3426305.
+ - Do not confuse a client hanging up with a connection time out. If a client
+ closes its side of the connection without sending a request line, do not
+ send the CLIENT_CONNECTION_TIMEOUT_RESPONSE, but report the condition
+ properly.
+ - Allow closing curly braces as part of action values as long as they are
+ escaped.
+ - On Windows, the logfile is now written before showing the GUI error
+ message which blocks until the user acknowledges it.
+ Reported by Adriaan in #3593603.
+ - Remove an unreasonable parameter limit in the CGI interface. The new
+ parameter limit depends on the memory available and is currently unlikely
+ to be reachable, due to other limits in both Privoxy and common clients.
+ Reported by Andrew on ijbswa-users@.
+ - Decrease the chances of parse failures after requests with unsupported
+ methods were sent to the CGI interface.
+
+*** Version 3.0.19 Stable ***
+
+- Bug fixes:
+ - Prevent a segmentation fault when de-chunking buffered content.
+ It could be triggered by malicious web servers if Privoxy was
+ configured to filter the content and running on a platform
+ where SIZE_T_MAX isn't larger than UINT_MAX, which probably
+ includes most 32-bit systems. On those platforms, all Privoxy
+ versions before 3.0.19 appear to be affected.
+ To be on the safe side, this bug should be presumed to allow
+ code execution as proving that it doesn't seems unrealistic.
+ - Do not expect a response from the SOCKS4/4A server until it
+ got something to respond to. This regression was introduced
+ in 3.0.18 and prevented the SOCKS4/4A negotiation from working.
+ Reported by qqqqqw in #3459781.
+
+- General improvements:
+ - Fix an off-by-one in an error message about connect failures.
+ - Use a GNUMakefile variable for the webserver root directory and
+ update the path. Sourceforge changed it which broke various
+ web-related targets.
+ - Update the CODE_STATUS description.
