<title>What's New in this Release</title>
<para>
- <application>Privoxy 3.0.13</application> introduces IPv6 support,
- improved keep-alive support and a bunch of minor improvements:
+ <application>Privoxy 3.0.16</application> is a stable release.
+ The changes since 3.0.15 beta are:
+</para>
+
+<para>
+ <itemizedlist>
+ <listitem>
+ <para>
+ Added the config file option handle-as-empty-doc-returns-ok to
+ work around Firefox bug #492459, which causes Firefox to hang
+ if JavaScripts are blocked in certain situations. The option is
+ enabled in the default config file.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Added the config file option default-server-timeout to control the
+ assumed default server timeout. Since Privoxy no longer returns
+ an error message for connection resets on reused client connections,
+ assuming larger server timeout values appears to actually work
+ pretty well as long as connections aren't shared.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Added optional support for FreeBSD's accf_http(9). Use the
+ configure option --enable-accept-filter to enable it.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Added fancier Privoxy icons for win32. Contributed by Jeff H.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Resolve localhost using whatever address family the operating
+ system feels like. Previous betas would try to use IPv4 as this
+ is what most users expect, but this didn't work reliable on
+ GNU/Linux systems.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ In the action lists on CGI pages, actions and their parameters are
+ no longer separated with a space. The action file parser doesn't
+ actually allow this and will throw an invalid syntax error if actions
+ and parameters in the action files are separated. Not adding the
+ spaces means copy and pasting CGI output into the action files works.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ The default keep-alive timeout has been reduced to 5 seconds to work
+ around hangs in clients that treat the proxy like any other host and
+ stop allowing any new connections if the "maximum number of
+ connections per host" is reached.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Several webbug URLs that look like they are leading to images are now
+ blocked as image instead of empty documents. Doing the latter causes
+ WebKit-based clients to show a "missing image" icon which may mess up
+ the layout.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ The no-such-domain template if used if for DNS resolution
+ problems with FEATURE_IPV6_SUPPORT enabled. Previously the
+ connect-failed template was used. Reported by 'zebul666'.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Accepts quoted expiration dates even though RFC 2109 10.1.2
+ doesn't seem to allow them. Reported anonymously.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Don't try to forget connections if connection sharing is disabled.
+ This wasn't a real problem but caused an unnecessary log message.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ The still undocumented --enable-extended-host-patterns configure
+ option has a better description.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Fixed an error message that would claim a write to the server
+ failed when actually writing to the client failed.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Log the crunch reason before trying to write to the client.
+ The log is easier to read that way.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Several log messages about client connections also mention
+ the socket number.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ handle-as-empty-document no longer depends on the image blocking
+ code being enabled.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ uagen, a Firefox User-Agent generator for Privoxy and Mozilla
+ browsers has been imported and is available in the tarballs
+ tools directory.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ The scripts in the tools directory treat unknown parameters
+ as fatal errors.
+ </para>
+ </listitem>
+ </itemizedlist>
+</para>

+<para>
+ If you missed the previous two beta versions, you may also be
+ interested in the additional changes since 3.0.12, the
+ last stable release:
</para>
<para>
</listitem>
<listitem>
<para>
- Added client-side keep-alive support. This should also allow
- NTLM authentication through Privoxy, but this hasn't been
- confirmed yet.
+ Added client-side keep-alive support.

</listitem>
<listitem>
option is enabled.
</para>
</listitem>
+ <listitem>
+ <para>
+ The latency is taken into account when evaluating whether or not to
+ reuse a connection. This should significantly reduce the number of
+ connections problems several users reported.
+ </para>
+ </listitem>
<listitem>
<para>
The max-client-connections option has been added to restrict
</listitem>
<listitem>
<para>
- Fixed a regression reintroduced in 3.0.12 that could cause
- crashes on mingw32 if header date randomization was enabled.
+ If the server doesn't specify how long the connection stays alive,
+ Privoxy errs on the safe side of caution and assumes it's only a second.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Setting keep-alive-timeout to 0 disables keep-alive support. Previously
+ Privoxy would claim to allow persistence but not reuse the connection.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Pipelined requests are less likely to be mistaken for the request
+ body of the previous request. Note that Privoxy still has no real
+ pipeline support and will either serialize pipelined requests or
+ drop them in which case the client has to resent them.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Fixed a crash on some Windows versions when header randomization
+ is enabled and the date couldn't be parsed.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Privoxy's keep-alive timeout for the current connection is reduced
+ to the one specified in the client's Keep-Alive header.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ For HTTP/1.1 requests, Privoxy implies keep-alive support by not
+ setting any Connection header instead of using 'Connection: keep-alive'.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ If the socket isn't reusable, Privoxy doesn't temporarily waste
+ a socket slot to remember the connection.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ If keep-alive support is disabled but compiled in, the client's
+ Keep-Alive header is removed.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Fixed a bug on mingw32 where downloading large files failed if
+ keep-alive support was enabled.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Fixed a bug that (at least theoretically) could cause log
+ timestamps to be occasionally off by about a second.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ The configure script respects the $PATH variable when searching
+ for groups and id.

</para>
</listitem>
+ <listitem>
+ <para>
+ In case of missing server data, no error message is send to the
+ client if the request arrived on a reused connection. The client
+ is then supposed to silently retry the request without bothering
+ the user. This should significantly reduce the frequency of the
+ "No server or forwarder data received" error message many users
+ reported.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ More reliable detection of prematurely closed client sockets
+ with keep-alive enabled.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
+ FEATURE_CONNECTION_SHARING and now available on
+ all platforms.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Improved handling of POST requests on reused connections.
+ Should fix problems with stalled connections after submitting
+ form data with some browser configurations.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Fixed various latency calculation issues.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Allows the client to pass NTLM authentication requests to a
+ forwarding proxy. This was already assumed and hinted to work
+ in 3.0.13 beta but actually didn't. Now it's confirmed to work
+ with IE, Firefox and Chrome.
+ Thanks to Francois Botha and Wan-Teh Chang
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Fixed a calculation problem if receiving the server headers
+ takes more than two reads, that could cause Privoxy to terminate
+ the connection prematurely. Reported by Oliver.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Compiles again on platforms such as OpenBSD and systems
+ using earlier glibc version that don't support AI_ADDRCONFIG.
+ Anonymously submitted in #2872591.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ A bunch of MS VC project files and Suse and Redhat RPM spec
+ files have been removed as they were no longer maintained for
+ quite some time.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Overly long action lines are properly rejected with a proper
+ error message. Previously they would be either rejected as
+ invalid or cause a core dump through abort().
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Already timed-out connections are no longer temporarily remembered.
+ They weren't reused anyway, but wasted a socket slot.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ len refers to the number of bytes actually read which might
+ differ from the ones received. Adjust log messages accordingly.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ The optional JavaScript on the CGI page uses encodeURIComponent()
+ instead of escape() which doesn't encode all characters that matter.
+ Anonymously reported in #2832722.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Fix gcc45 warnings in decompress_iob().
