><P
-> There are many improvements and new features since <SPAN
+> <SPAN
CLASS="APPLICATION"
->Privoxy 3.0.8</SPAN
->, the last stable release:</P
+>Privoxy 3.0.26</SPAN
+> stable is a bug-fix release
+ for the previously released 3.0.25 beta which introduced client-specific
+ tags and included a couple of minor improvements.</P
><P
-> <P
></P
><UL
><LI
><P
-> Added SOCKS5 support (with address resolution done by
- the SOCKS5 server). Patch provided by Eric M. Hopper.
+> Bug fixes:
</P
+><P
+></P
+><UL
+><LI
+><P
+> Fixed crashes with "listen-addr :8118" (SF Bug #902).
+ The regression was introduced in 3.0.25 beta and reported
+ by Marvin Renich in Debian bug #834941.
+ </P
+></LI
+></UL
></LI
><LI
><P
-> The "blocked" CGI pages include a block reason that was
- provided as argument to the last-applying block action.
+> General improvements:
</P
+><P
+></P
+><UL
+><LI
+><P
+> Log when privoxy is toggled on or off via cgi interface.
+ </P
></LI
><LI
><P
-> 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.
- </P
+> Highlight the "Info: Now toggled " on/off log message
+ in the Windows log viewer.
+ </P
></LI
><LI
><P
-> Forbidden CONNECT requests are treated like blocks by default.
- The now-pointless treat-forbidden-connects-like-blocks action
- has been removed.
- </P
+> Highlight the loading actions/filter file log message
+ in the Windows log viewer.
+ </P
></LI
><LI
><P
-> 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.
- </P
+> Mention client-specific tags on the toggle page as a
+ potentionally more appropriate alternative.
+ </P
+></LI
+></UL
></LI
><LI
><P
-> 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.
+> Documentation improvements:
</P
+><P
+></P
+><UL
+><LI
+><P
+> Update download section on the homepage.
+ The downloads are available from the website now.
+ </P
></LI
><LI
><P
-> 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.
- </P
+> Add sponsor FAQ.
+ </P
></LI
><LI
><P
-> 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.
- </P
+> Remove obsolete reference to mailing lists hosted at SourceForge.
+ </P
></LI
><LI
><P
-> Host information is gathered outside the main thread so it's less
- likely to delay other incoming connections if the host is misconfigured.
- </P
+> Update the "Before the Release" section of the developer manual.
+ </P
+></LI
+></UL
></LI
><LI
><P
-> 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.
+> Infrastructure improvements:
</P
+><P
+></P
+><UL
+><LI
+><P
+> Add perl script to generate an RSS feed for the packages
+ Submitted by "Unknown".
+ </P
+></LI
+></UL
></LI
><LI
><P
-> 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".
+> Build system improvements:
</P
+><P
+></P
+><UL
+><LI
+><P
+> strptime.h: fix a compiler warning about ambiguous else.
+ </P
></LI
><LI
><P
-> Fixed false-positives with the link-by-url filter and URLs that
- contain the pattern "/jump/".
- </P
+> configure.in: Check for Docbook goo on the BSDs as well.
+ </P
></LI
><LI
><P
-> The less-download-windows filter no longer messes
- "Content-Type: application/x-shockwave-flash" headers up.
- </P
+> GNUMakefile.in: Let the dok-user target remove temporary files.
+ </P
+></LI
+></UL
></LI
+></UL
+><P
+> Changes between <SPAN
+CLASS="APPLICATION"
+>Privoxy 3.0.25 beta</SPAN
+>
+ and the previous release:</P
+><P
+></P
+><UL
><LI
><P
-> In the show-url-info page's "Final results" section active and
- inactive actions are listed separately. Patch provided by Lee.
+> Bug fixes:
</P
+><P
+></P
+><UL
+><LI
+><P
+> Always use the current toggle state for new requests.
+ Previously new requests on reused connections inherited
+ the toggle state from the previous request even though
+ the toggle state could have changed.
+ Reported by Robert Klemme.
+ </P
></LI
><LI
><P
-> The GNUmakefile supports the DESTDIR variable. Patch for
- the install target submitted by Radoslaw Zielinski.
- </P
+> Fixed two buffer-overflows in the (deprecated) static
+ pcre code. These bugs are not considered security issues
+ as the input is trusted.
+ Found with afl-fuzz and ASAN.
+ </P
+></LI
+></UL
></LI
><LI
><P
-> 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.
+> General improvements:
</P
+><P
+></P
+><UL
+><LI
+><P
+> Added support for client-specific tags which allow Privoxy
+ admins to pre-define tags that are set for all requests from
+ clients that previously opted in through the CGI interface.
+ They are useful in multi-user setups where admins may
+ want to allow users to disable certain actions and filters
+ for themselves without affecting others.
+ In single-user setups they are useful to allow more fine-grained
+ toggling. For example to disable request blocking while still
+ crunching cookies, or to disable experimental filters only.
+ This is an experimental feature, the syntax and behaviour may
+ change in future versions.
+ Sponsored by Robert Klemme.
+ </P
></LI
><LI
><P
-> 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.
- </P
+> Dynamic filters and taggers now support a $listen-address variable
+ which contains the address the request came in on.
+ For external filters the variable is called $PRIVOXY_LISTEN_ADDRESS.
+ Original patch contributed by pursievro.
+ </P
></LI
><LI
><P
-> The show-url-info page provides an OpenSearch Description that
- allows to access the page through browser search plugins.
- </P
+> Add client-header-tagger 'listen-address'.
+ </P
></LI
><LI
><P
-> The obsolete kill-popups action has been removed as the
- PCRS-based popup filters can do the same and are slightly
- less unreliable.
- </P
+> Include the listen-address in the log message when logging new requests.
+ Patch contributed by pursievro.
+ </P
></LI
><LI
><P
-> The inspect-jpegs action has been removed.
- </P
+> Turn invalid max-client-connections values into fatal errors.
+ </P
></LI
><LI
><P
-> 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.
- </P
+> The show-status page now shows whether or not dates before 1970
+ and after 2038 are expected to be handled properly.
+ This is mainly useful for Privoxy-Regression-Test but could
+ also come handy when dealing with time-related support requests.
+ </P
></LI
><LI
><P
-> Privoxy-Regression-Test has been significantly improved.
- </P
+> On Mac OS X the thread id in log messages are more likely to
+ be unique now.
+ </P
></LI
><LI
><P
-> Most sections in the default.action file contain tests for
- Privoxy-Regression-Test to verify that they are working as intended.
- </P
+> When complaining about missing filters, the filter type is logged
+ as well.
+ </P
></LI
><LI
><P
-> Parts of Privoxy have been refactored to increase maintainability.
- </P
+> A couple of harmless coverity warnings were silenced
+ (CID #161202, CID #161203, CID #161211).
+ </P
+></LI
+></UL
></LI
><LI
><P
-> Building with zlib (if available) is done by default.
+> Action file improvements:
</P
+><P
+></P
+><UL
+><LI
+><P
+> Filtering is disabled for Range requests to let download resumption
+ and Windows updates work with the default configuration.
+ </P
+></LI
+><LI
+><P
+> Unblock ".ardmediathek.de/".
+ Reported by ThTomate in #932.
+ </P
+></LI
+></UL
></LI
><LI
><P
-> 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.
