ChangeLog for Privoxy
--------------------------------------------------------------------
+*** 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. Donations
+ are still welcome too: http://www.privoxy.org/faq/general.html#DONATE
+
+*** Version 3.0.12 ***
+
+- The socket-timeout option now also works on platforms whose
+ select() implementation modifies the timeout structure.
+ Previously the timeout was triggered even if the connection
+ didn't stall. Reported by cyberpatrol.
+- The Connection: keep-alive code properly deals with files
+ larger than 2GB. Previously the connection was closed too
+ early.
+- The content length for files above 2GB is logged correctly.
+- The user-manual directive on the show-status page links to
+ the documentation location specified with the directive,
+ not to the Privoxy website.
+- When running in daemon mode, Privoxy doesn't log anything
+ to the console unless there are errors before the logfile
+ has been opened.
+- The show-status page prints warnings about invalid directives
+ on the same line as the directives themselves.
+- Fixed several justified (but harmless) compiler warnings,
+ mostly on 64 bit platforms.
+- The mingw32 version explicitly requests the default charset
+ to prevent display problems with some fonts available on more
+ recent Windows versions. Patch by Burberry.
+- The mingw32 version uses the Privoxy icon in the alt-tab
+ windows. Patch by Burberry.
+- The timestamp and the thread id is omitted in the "Fatal error"
+ message box on mingw32.
+- Fixed two related mingw32-only buffer overflows. Triggering
+ them required control over the configuration file, therefore
+ this isn't seen as a security issue.
+- In verbose mode, or if the new option --show-skipped-tests
+ is used, Privoxy-Regression-Test logs skipped tests and the
+ skip reason.
+
*** Version 3.0.11 ***
- On most platforms, outgoing connections can be kept alive and
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()".
+- 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.
-- 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 changed if Privoxy
- is toggled of. XXX: Describe how.
- 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
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).

+- The mingw32 version's task bar icon is crossed out and
+ the color changed to gray if Privoxy is toggled off.
