ChangeLog for Privoxy
--------------------------------------------------------------------
-*** Since 3.0.7 ***
+*** 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 3.0.10 ***
+
+- Ordinary configuration file changes no longer cause program
+ termination on OS/2 if the name of the logfile hasn't been
+ changed as well. This regression probably crept in with the
+ logging improvements in 3.0.7. Reported by Maynard.
+- The img-reorder filter is less likely to mess up JavaScript code in
+ img tags. Problem and solution reported by Glenn Washburn in #2014552.
+- The source tar ball now includes Privoxy-Log-Parser,
+ a syntax-highlighter for Privoxy logs. For fancy screenshots see:
+ http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
+ Documentation is available through perldoc(1).
+
+*** Version 3.0.9 Beta ***
+
+- Added SOCKS5 support (with address resolution done by
+ the SOCKS5 server). Patch provided by Eric M. Hopper.
+- The "blocked" CGI pages include a block reason that was
+ provided as argument to the last-applying block action.
+- If enable-edit-actions is disabled (the default since 3.0.7 beta)
+ the show-status page hides the edit buttons and explains why.
+ Previously the user would get the "this feature has been disabled"
+ message after using the edit button.
+- Forbidden CONNECT requests are treated like blocks by default.
+ The now-pointless treat-forbidden-connects-like-blocks action
+ has been removed.
+- Not enabling limit-connect now allows CONNECT requests to all ports.
+ In previous versions it would only allow CONNECT requests to port 443.
+ Use +limit-connect{443} if you think you need the old default behaviour.
+- The CGI editor gets turned off after three edit requests with invalid
+ file modification timestamps. This makes life harder for attackers
+ who can leverage browser bugs to send fake Referers and intend to
+ brute-force edit URLs.
+- Action settings for multiple patterns in the same section are
+ shared in memory. As a result these sections take up less space
+ (and are loaded slightly faster). Problem reported by Franz Schwartau.
+- Linear white space in HTTP headers will be normalized to single
+ spaces before parsing the header's content, headers split across
+ multiple lines get merged first. This should prevent problems like:
+ * letting the session-cookies-only action slip
+ some Cookies through unmodified,
+ * only suppressing the first line of a header,
+ thus creating an invalid one, and
+ * to incorrectly block headers with valid timestamps
+ that weren't properly recognized.
+ Headers that could trigger these problems are unlikely to appear
+ in "normal" web traffic, but could be intentionally generated to
+ fool some of Privoxy's header parsers.
+- Host information is gathered outside the main thread so it's less
+ likely to delay other incoming connections if the host is misconfigured.
+- New config option "hostname" to use a hostname other than
+ the one returned by the operating system. Useful to speed-up responses
+ for CGI requests on misconfigured systems. Requested by Max Khon.
+- The CGI editor supports the "disable all filters of this type"
+ directives "-client-header-filter", "-server-header-filter",
+ "-client-header-tagger" and "-server-header-tagger".
+- Fixed false-positives with the link-by-url filter and URLs that
+ contain the pattern "/jump/".
+- The less-download-windows filter no longer messes
+ "Content-Type: application/x-shockwave-flash" headers up.
+- In the show-url-info page's "Final results" section active and
+ inactive actions are listed separately. Patch provided by Lee.
+- The GNUmakefile supports the DESTDIR variable. Patch for
+ the install target submitted by Radoslaw Zielinski.
+- Embedding the content of configuration files in the show-status
+ page is significantly faster now. For a largish action file (1 MB)
+ a speedup of about 2450 times has been measured. This is mostly
+ interesting if you are using large action files or regularly use
+ Privoxy-Regression-Test while running Privoxy through Valgrind,
+ for stock configuration files it doesn't really matter.
+- If zlib support is unavailable and there are content
+ filters active but the prevent-compression action is disabled,
+ the show-url-info page includes a warning that compression
+ might prevent filtering.
+- The show-url-info page provides an OpenSearch Description that
+ allows to access the page through browser search plugins.
+- Custom client-header filters that rewrite the request line
+ incorrectly no longer cause Privoxy to crash. Reported by din_a4.
+- The obsolete kill-popups action has been removed as the
+ PCRS-based popup filters can do the same and are slightly
+ less unreliable.
+- The inspect-jpegs action has been removed.
+- The send-wafer and send-vanilla-wafer actions have been removed.
+ They weren't particular useful and their behaviour could be emulated
+ with add-header anyway.
+- Privoxy-Regression-Test has been significantly improved.
+- Most sections in the default.action file contain tests for
+ Privoxy-Regression-Test to verify that they are working as intended.
+- Parts of Privoxy have been refactored to increase maintainability.
+- Building with zlib (if available) is done by default.
+
+*** Version 3.0.8 ***
- Fixed a small memory leak when listen-address only specifies the port.
- The source tar balls now include Privoxy-Regression-Test which
don't exist.
- Treat the non-standard Request-Range headers like standard range
headers and suppress them if content filtering is enabled.
-- Fix build on OS/2 and other platforms that are neither
- Windows nor Unix based.
- Prevent the log messages for CONNECT requests to unacceptable
ports from printing the limit-connect argument as [null] if
limit-connect hasn't been explicitly enabled.
Earlier Privoxy versions would buffer and then forward the content
unmodified which caused some browsers to simply show empty pages.
- Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
-- The code to add X-Forwarded-For headers has been removed.
+- The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
+ action isn't being used has been removed.
- Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
Reported by Lee.
- Minor code clean-ups, filter and action file updates.
