-> Header filtering can be done with dedicated header filters now. As a result

- that were introduced with <SPAN

+> 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.
+ </P

+><P
+> Passing invalid users or groups with the --user option
+ didn't lead to program exit. Regression introduced in 3.0.7.
+ </P
+></LI
+><LI
+><P
+> 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.
+ </P
+></LI

+><P
+> The standard.action file has been removed. Its content
+ is now part of the default.action file.
+ </P

+> In some situations the logged content length was slightly too low.

+><LI
+><P
+> 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".
+ </P
+></LI
+><LI
+><P
+> The crunch reason has been moved to the beginning of the
+ crunch message. For HTTP URLs, the protocol is logged as well.
+ </P

+><LI
+><P
+> Log messages are shortened by not printing the thread id
+ on its own (as opposed to putting it inside "Privoxy()".
+ </P
+></LI
+><LI
+><P
+> The config option socket-timeout has been added to control
+ the time Privoxy waits for data to arrive on a socket.
+ </P
+></LI
+><LI
+><P
+> 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.
+ </P

+> Responses from shoutcast servers are accepted again.
+ Problem reported and fix suggested by Stefan.

+><P
+> 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).
+ </P
+></LI
+><LI
+><P
+> 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.
+ </P
+></LI
+><LI
+><P
+> 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.
+ </P
+></LI
+><LI
+><P
+> The mingw32 version's task bar icon is crossed out and
+ the color changed to gray if Privoxy is toggled off.

->
- Some installers may remove earlier versions completely, including
- configuration files. Save any important configuration files!
+> The recommended way to upgrade <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> is to backup your old
+ configuration files, install the new ones, verify that <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>
+ is working correctly and finally merge back your changes using
+ <SPAN
+CLASS="APPLICATION"
+>diff</SPAN
+> and maybe <SPAN
+CLASS="APPLICATION"
+>patch</SPAN
+>.

- On the other hand, other installers may not overwrite any existing configuration
- files, thinking you will want to do that. You may want to manually check
- your saved files against the newer versions to see if the improvements have
- merit, or whether there are new options that you may want to consider.
- There are a number of new features, but most won't be available unless
- these features are incorporated into your configuration somehow.
+> There are a number of new features in each <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> release and
+ most of them have to be explicitly enabled in the configuration
+ files. Old configuration files obviously don't do that and due
+ to syntax changes using old configuration files with a new
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> isn't always possible anyway.

-> The default setting has filtering turned <SPAN

- subsequently means that compression is <SPAN
-CLASS="emphasis"
-><I
-CLASS="EMPHASIS"
->on</I
-></SPAN
->. Remember
- that filtering does not work on compressed pages, so if you use, or want to
- use, filtering, you will need to force compression off. Example:
