-*** 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 3.0.21 stable ***
+
+- Bug fixes:
+ - On POSIX-like platforms, network sockets with file descriptor
+ values above FD_SETSIZE are properly rejected. Previously they
+ could cause memory corruption in configurations that allowed
+ the limit to be reached.
+ - Proxy authentication headers are removed unless the new directive
+ enable-proxy-authentication-forwarding is used. Forwarding the
+ headers potentially allows malicious sites to trick the user
+ into providing them with login information.
+ Reported by Chris John Riley.
+ - Compiles on OS/2 again now that unistd.h is only included
+ on platforms that have it.
+
+- General improvements:
+ - The show-status page shows the FEATURE_STRPTIME_SANITY_CHECKS status.
+ - A couple of assert()s that could theoretically dereference
+ NULL pointers in debug builds have been relocated.
+ - Added an LSB info block to the generic start script.
+ Based on a patch from Natxo Asenjo.
+ - The max-client-connections default has been changed to 128
+ which should be more than enough for most setups.
+
+- Action file improvements:
+ - Block rover.ebay./ar.*\&adtype= instead of "/.*\&adtype=" which
+ caused too man false positives.
+ Reported by u302320 in #360284, additional feedback from Adam Piggott.
+ - Unblock '.advrider.com/' and '/.*ADVrider'.
+ Anonymously reported in #3603636.
+ - Stop blocking '/js/slider\.js'.
+ Reported by Adam Piggott in #3606635 and _lvm in #2791160.
+
+- Filter file improvements:
+ - Added an iframes filter.
+
+- Documentation improvements:
+ - The whole GPLv2 text is included in the user manual now,
+ so Privoxy can serve it itself and the user can read it
+ without having to wade through GPLv3 ads first.
+ - Properly numbered and underlined a couple of section titles
+ in the config that where previously overlooked due to a flaw
+ in the conversion script. Reported by Ralf Jungblut.
+ - Improved the support instruction to hopefully make it harder to
+ unintentionally provide insufficient information when requesting
+ support. Previously it wasn't obvious that the information we need
+ in bug reports is usually also required in support requests.
+ - Removed documentation about packages that haven't been provided
+ in years.
+
+- Privoxy-Regression-Test:
+ - Only log the test number when not running in verbose mode
+ The position of the test is rarely relevant and it previously
+ wasn't exactly obvious which one of the numbers was useful to
+ repeat the test with --test-number.
+
+- GNUmakefile improvements:
+ - Factor generate-config-file out of config-file to make testing
+ more convenient.
+ - The clean target now also takes care of patch leftovers.
+
+*** 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 receiving 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.
+
+- Action file improvements:
+ - Remove the comment that indicated that updated default.action versions
+ are released on their own.
+ - Block 'optimize.indieclick.com/' and 'optimized-by.rubiconproject.com/'
+ - Unblock 'adjamblog.wordpress.com/' and 'adjamblog.files.wordpress.com/'.
+ Reported by Ryan Farmer in #3496116.
+ - Unblock '/.*Bugtracker'. Reported by pwhk in #3522341.
+ - Add test URLs for '.freebsd.org' and '.watson.org'.
+ - Unblock '.urbandictionary.com/popular'.
+ - Block '.adnxs.com/'.

+ - Block 'gm-link.com/' which is used for email tracking.
+ Reported by David Bo in #1812733.
+ - Verify that requests to "bwp." are blocked. URL taken from #1736879
+ submitted by Francois Marier.
+ - Block '/.*bannerid='. Reported by Adam Piggott in #2975779.
+ - Block 'cltomedia.info/delivery/' and '.adexprt.com/'.
+ Anonymously reported in #2965254.
+ - Block 'de17a.com/'. Reported by David Bo in #3061472.
+ - Block 'oskar.tradera.com/'. Reported by David Bo in #3060596.
+ - Block '/scripts/webtrends\.js'. Reported by johnd16 in #3002729.
+ - Block requests for 'pool.*.adhese.com/'. Reported by johnd16 in #3002716.
+ - Update path pattern for Coremetrics and add tests.
+ Pattern and URLs submitted by Adam Piggott #3168443.
+ - Enable +fast-redirects{check-decoded-url} for 'tr.anp.se/'.
+ Reported by David Bo in #3268832.

+ infected" page.
+ - Unblock '/.*download' to resolve actionsfile feedback #3498129.
+ Submitted by Steven Kolins (soundcloud.com not working).
+ - Unblock '.wlxrs.com/' which is required by hotmail.com.
+ Fixes #3413827 submitted by David Bo.
+ - Add two unblock patterns for popup radio and TV players.
+ Submitted by Adam Piggott in #3596089.
+
+- Filter file improvements & bug fixes:
+ - Add a referer tagger.
+ - Reduce the likelihood that the google filter messes up HTML-generating
+ JavaScript. Reported by Zeno Kugy in #3520260.
+
+- Documentation improvements:
+ - Revised all OS X sections due to new packaging module (OSXPackageBuilder).
+ - Update the list of supported operating systems to clarify that all Windows
+ versions after 95 are expected to work and note that the platform-specific
+ code for AmigaOS and QNX currently isn't maintained.
+ - Update 'Signals' section, the only explicitly handled signals are SIGINT,
+ SIGTERM and SIGHUP.
+ - Add Haiku to the list of operating systems on which Privoxy is known to
+ run.
+ - Add DragonFly to the list of BSDs on which Privoxy is known to run.
+ - Removed references to redhat-specific documentation set since it no longer
+ exists.
+ - Removed references to building PDFs since we no longer do so.
+ - Multiple listen-address directives are supported since 3.0.18, correct the
+ documentation to say so.
+ - Remove bogus section about long and short being preferable to int.
+ - Corrected some Internet JunkBuster references to Privoxy.
+ - Removed references to www.junkbusters.com since it is no longer
+ maintained. Reported by Angelina Matson.
+ - Various grammar and spelling corrections
+ - Add a client-header-tagger{} example for disabling filtering for range
+ requests.
+ - Correct a URL in the "Privoxy with Tor" FAQ.
+ - Spell 'refresh-tags' correctly. Reported by Don in #3571927.
+ - Sort manpage options alphabetically.
+ - Remove an incorrect sentence in the toggle section. The toggle state
+ doesn't affect whether or not the Windows version uses the tray icon.
+ Reported by Zeno Kugy in #3596395.
+ - Add new contributors since 3.0.19.
+
+- Log message improvements:
+ - When stopping to watch a client socket due to pipelining, additionally log
+ the socket number.
+ - Log the client socket and its condition before closing it. This makes it
+ more obvious that the socket actually gets closed and should help when
+ diagnosing problems like #3464439.
+ - In case of SOCKS5 failures, do not explicitly log the server's response.
+ It hasn't helped so far and the response can already be logged by enabling
+ "debug 32768" anyway. This reverts v1.81 and the follow-up bug fix v1.84.
+ - Relocate the connection-accepted message from listen_loop() to serve().
+ This way it's printed by the thread that is actually serving the
+ connection which is nice when grepping for thread ids in log files.
+
+- Code cleanups:
+ - Remove compatibility layer for versions prior to 3.0 since it has been
+ obsolete for more than 10 years now.
+ - Remove the ijb_isupper() and ijb_tolower() macros from parsers.c since
+ they aren't used in this file.
+ - Removed the 'Functions declared include:' comment sections since they tend
+ to be incomplete, incorrect and out of date and the benefit seems
+ questionable.
+ - Various comment grammar and comprehensibility improvements.
+ - Remove a pointless fflush() call in chat(). Flushing all streams pretty
+ much all the time for no obvious reason is ridiculous.
+ - Relocate ijb_isupper()'s definition to project.h and get the ijb_tolower()
+ definition from there, too.
+ - Relocate ijb_isdigit()'s definition to project.h.
+ - Rename ijb_foo macros to privoxy_foo.
+ - Add malloc_or_die() which will allow to simplify code paths where malloc()
+ failures don't need to be handled gracefully.
+ - Add strdup_or_die() which will allow to simplify code paths where strdup()
+ failures don't need to be handled gracefully.
+ - Replace strdup() calls with strdup_or_die() calls where it's safe and
+ simplifies the code.
+ - Fix white-space around parentheses.
+ - Add missing white-space behind if's and the following parentheses.
+ - Unwrap a memcpy() call in resolve_hostname_to_ip().
+ - Declare pcrs_get_delimiter()'s delimiters[] static const.
+ - Various optimisations to remove dead code and merge inefficient code
+ structures for improved clarity, performance or code compactness.
+ - Various data type corrections.
+ - Change visibility of several code segments when compiling without
+ FEATURE_CONNECTION_KEEP_ALIVE enabled for clarity.
+ - In pcrs_get_delimiter(), do not use delimiters outside the ASCII range.
+ Fixes a clang complaint.
+ - Fix an error message in get_last_url() nobody is supposed to see.
+ Reported by Matthew Fischer in #3507301.
+ - Fix a typo in the no-zlib-support complaint. Patch submitted by Matthew
+ Fischer in #3507304.
+ - Shorten ssplit()'s prototype by removing the last two arguments. We always
+ want to skip empty fields and ignore leading delimiters, so having
+ parameters for this only complicates the API.
+ - Use an enum for the type of the action value.
+ - Rename action_name's member takes_value to value_type as it isn't used as
+ boolean.
+ - Turn family mismatches in match_sockaddr() into fatal errors.
+ - Let enlist_unique_header() verify that the caller didn't pass a header
+ containing either \r or \n.
+ - Change the hashes used in load_config() to unsigned int. That's what
+ hash_string() actually returns and using a potentially larger type
+ is at best useless.
+ - Use privoxy_tolower() instead of vanilla tolower() with manual casting of
+ the argument.
+ - Catch ssplit() failures in parse_cgi_parameters().
+
+- Privoxy-Regression-Test:
+ - Add an 'Overwrite condition' directive to skip any matching tests before
+ it. As it has a global scope, using it is more convenient than clowning
+ around with the Ignore directive.
+ - Log to STDOUT instead of STDERR.
+ - Include the Privoxy version in the output.
+ - Various grammar and spelling corrections in documentation and code.
+ - Additional tests for range requests with filtering enabled.
+ - Tests with mostly invalid range request.
+ - Add a couple of hide-if-modified-since{} tests with different date formats.
+ - Cleaned up the format of the regression-tests.action file to match the
+ format of default.action.
+ - Remove the "Copyright" line from print_version(). When using --help, every
+ line of screen space matters and thus shouldn't be wasted on things the
+ user doesn't care about.
+
+- Privoxy-Log-Parser:
+ - Improve the --statistics performance by skipping sanity checks for input
+ that shouldn't affect the results anyway. Add a --strict-checks option
+ that enables some of the checks again, just in case anybody cares.
+ - The distribution of client requests per connection is included in
+ the --statistic output.
+ - The --accept-unknown-messages option has been removed and the behavior
+ is now the default.
+ - Accept and (mostly) highlight new log messages introduced with
+ Privoxy 3.0.20.
+
+- uagen:
+ - Bump generated Firefox version to 17.
+
+- GNUmakefile improvements:
+ - The dok-tidy target no longer taints documents with a tidy-mark
+ - Change RA_MODE from 0664 to 0644. Suggested by Markus Dittrich in
+ #3505445.
+ - Remove tidy's clean flag as it changes the scope of attributes.
+ Link-specific colors end up being applied to all text. Reported by Adam
+ Piggott in #3569551.
+ - Leave it up to the user whether or not smart tags are inserted.
+ - Let w3m itself do the line wrapping for the config file. It works better
+ than fmt as it can honour pre tags causing less unintentional line breaks.
+ - Ditch a pointless '-r' passed to rm to delete files.
+ - The config-file target now requires less manual intervention and updates
+ the original config.
+ - Change WDUMP to generate ASCII. Add WDUMP_UTF8 to allow UTF-8 in the
+ AUTHORS file so the names are right.
+ - Stop pretending that lynx and links are supported for the documentation.
+
+- configure improvements:
+ - On Haiku, do not pass -lpthread to the compiler. Haiku's pthreads
+ implementation is contained in its system library, libroot, so no
+ additional library needs to be searched.
+ Patch submitted by Simon South in #3564815.
+ - Additional Haiku-specific improvements. Disable checks intended for
+ multi-user systems as Haiku is presently single-user. Group Haiku-specific
+ settings in their own section, following the pattern for Solaris, OS/2 and
+ AmigaOS. Add additional library-related settings to remove the need for
+ providing configure with custom LDFLAGS.
+ Submitted by Simon South in #3574538.
