+> <SPAN
CLASS="APPLICATION"
->Privoxy 3.0.6</SPAN
->, the last stable release:</P
+>Privoxy 3.0.16</SPAN
+> is a stable release.

><P

><UL
><LI
><P
-> Two new actions <A
-HREF="actions-file.html#SERVER-HEADER-TAGGER"
->server-header-tagger</A
->
- and <A
-HREF="actions-file.html#CLIENT-HEADER-TAGGER"
->client-header-tagger</A
->
- that can be used to create arbitrary <SPAN
-CLASS="QUOTE"
->"tags"</SPAN
->
- based on client and server headers.
- These <SPAN
-CLASS="QUOTE"
->"tags"</SPAN
-> can then subsequently be used
- to control the other actions used for the current request,
- greatly increasing <SPAN
-CLASS="APPLICATION"
->Privoxy</SPAN
->'s flexibility and selectivity. See <A
-HREF="actions-file.html#TAG-PATTERN"
->tag patterns</A
-> for more information on tags.
+> 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
><LI
><P
-> Header filtering is 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
- content filters to the headers have been removed.
- See the new actions <A
-HREF="actions-file.html#SERVER-HEADER-FILTER"
->server-header-filter</A
->
- and <A
-HREF="actions-file.html#CLIENT-HEADER-FILTER"
->client-header-filter</A
-> for details.
+> 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
-> There are four new options for the main <TT
-CLASS="FILENAME"
->config</TT
-> file:
+> 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

+><P
+> The IPv6 code is enabled by default on Windows versions that support it.
+ Patch submitted by oCameLo in #2942729.

+> 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.
</P

+ <P
></P
><UL
><LI
><P
-> <A
-HREF="config.html#ALLOW-CGI-REQUEST-CRUNCHING"
->allow-cgi-request-crunching</A
->
- which allows requests for Privoxy's internal CGI pages to be
- blocked, redirected or (un)trusted like ordinary requests.
- </P
+> In finish_http_response(), continue to add the 'Connection: close'
+ header if the client connection will not be kept alive.
+ Anonymously pointed out in #2987454.
+ </P
></LI
><LI
><P
-> <A
-HREF="config.html#SPLIT-LARGE-FORMS"
->split-large-forms</A
->
- that will work around a browser bug that caused IE6 and IE7 to
- ignore the Submit button on the Privoxy's edit-actions-for-url CGI
- page.
- </P
+> Apostrophes in block messages no longer cause parse errors
+ when the blocked page is viewed with JavaScript enabled.
+ Reported by dg1727 in #3062296.
+ </P
></LI
><LI
><P
-> <A
-HREF="config.html#ACCEPT-INTERCEPTED-REQUESTS"
->accept-intercepted-requests</A
->
- which allows to combine Privoxy with any packet filter to create an
- intercepting proxy for HTTP/1.1 requests (and for HTTP/1.0 requests
- with Host header set). This means clients can be forced to use
- <SPAN
-CLASS="APPLICATION"
->Privoxy</SPAN
-> even if their proxy settings are configured differently.
- </P
+> Fix a bunch of anchors that used underscores instead of dashes.
+ </P
></LI
><LI
><P
-> <A
-HREF="config.html#TEMPLDIR"
->templdir</A
->
- to designate an alternate location for <SPAN
-CLASS="APPLICATION"
->Privoxy</SPAN
->'s
- locally customized CGI templates so that
- these are not overwritten during upgrades.
- </P
+> Allow to keep the client connection alive after crunching the previous request.
+ Already opened server connections can be kept alive, too.
+ </P
></LI
-></UL

+ </P
></LI
><LI
><P
-> A new command line option <TT
-CLASS="LITERAL"
->--pre-chroot-nslookup hostname</TT
-> to
- initialize the resolver library before chroot'ing. On some systems this
- reduces the number of files that must be copied into the chroot tree.
- (Patch provided by Stephen Gildea)
+> Show the 404 CGI page if cgi_send_user_manual() is called while
+ local user manual delivery is disabled.

><P
-> The <A
-HREF="actions-file.html#FORWARD-OVERRIDE"

- allows changing of the forwarding settings through the actions files.
