-> There are many improvements and new features since <SPAN
+> <SPAN
CLASS="APPLICATION"
->Privoxy 3.0.6</SPAN
->, the last stable release:</P
+>Privoxy 3.0.16</SPAN
+> is a stable release.
+ The changes since 3.0.15 beta are:</P
><P

><UL
><LI
><P
-> Header filtering can be done with dedicated header filters now. As a result
- the actions <SPAN
-CLASS="QUOTE"
->"filter-client-headers"</SPAN
-> and <SPAN
-CLASS="QUOTE"
->"filter-server-headers"</SPAN
->
- that were introduced with <SPAN
-CLASS="APPLICATION"
->Privoxy 3.0.5</SPAN
-> to apply
- the content filters to the headers as, well have been removed again.
+> Fixed last-chunk-detection for responses where the content was small
+ enough to be read with the body, causing Privoxy to wait for the
+ end of the content until the server closed the connection.
+ Reported by "Karsten" in #3028326.
</P
></LI
-></UL
+><LI
+><P
+> Responses with status code 204 weren't properly detected as body-less
+ like RFC2616 mandates. Like the previous bug, this caused Privoxy
+ to wait for the end of the content until the server closed the connection.
+ Fixes #3022042 and #3025553, reported by a user with no visible name.
+ Most likely also fixes a bunch of other AJAX-related problem reports
+ that got closed in the past due to insufficient information and lack
+ of feedback.
+ </P
+></LI
+><LI
+><P
+> Fixed an ACL bug that made it impossible to build a blacklist.
+ Usually the ACL directives are used in a whitelist, which worked
+ as expected, but blacklisting is still useful for public proxies
+ where one only needs to deny known abusers access.
+ </P
+></LI
+><LI
+><P
+> Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
+ network. This should make debugging various parsing issues a lot easier.
+ </P
+></LI
+><LI
+><P
+> The IPv6 code is enabled by default on Windows versions that support it.
+ Patch submitted by oCameLo in #2942729.
+ </P
+></LI
+><LI
+><P
+> In mingw32 versions, the user.filter file is reachable through the
+ GUI, just like default.filter is. Feature request 3040263.
+ </P
+></LI
+><LI
+><P
+> Added the configure option --enable-large-file-support to set a few
+ defines that are required by platforms like GNU/Linux to support files
+ larger then 2GB. Mainly interesting for users without proper logfile
+ management.
+ </P
+></LI
+><LI
+><P
+> Logging with "debug 16" no longer stops at the first nul byte which is
+ pretty useless. Non-printable characters are replaced with their hex value
+ so the result can't span multiple lines making parsing them harder then
+ necessary.
+ </P
+></LI
+><LI
+><P
+> Privoxy logs when reading an action, filter or trust file.
+ </P
+></LI
+><LI
+><P
+> Fixed incorrect regression test markup which caused a test in
+ 3.0.16 to fail while Privoxy itself was working correctly.
+ While Privoxy accepts hide-referer, too, the action name is actually
+ hide-referrer which is also the name used one the final results page,
+ where the test expected the alias.

-><I

- that filtering does not work on compressed pages, so if you use, or want to
