As a side effect, - the "no thread-safe PRNG" warning could be removed as well. + 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. - 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. + 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. - 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). + Added optional support for FreeBSD's accf_http(9). Use the + configure option --enable-accept-filter to enable it. + + + + + Added fancier Privoxy icons for win32. Contributed by Jeff H. + + + + + In daemon mode, fd 0, 1 and 2 are bound to /dev/null. + + + + + 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 reliably on + GNU/Linux systems. + + + + + 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. + + + + + 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. + + + + + 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. + + + + + The no-such-domain template is used for DNS resolution + problems with FEATURE_IPV6_SUPPORT enabled. Previously the + connect-failed template was used. Reported by 'zebul666'. + + + + + Accepts quoted expiration dates even though RFC 2109 10.1.2 + doesn't seem to allow them.

Thanks to Petr Pisar who not only provided + the initial patch but also helped a lot with the integration. + + + + + Added client-side keep-alive support. + + + + + The connection sharing code is only used if the connection-sharing + option is enabled. + + + + + 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. + + + + + The max-client-connections option has been added to restrict + the number of client connections below a value enforced by + the operating system. + + + + + 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. + + + + + Setting keep-alive-timeout to 0 disables keep-alive support. Previously + Privoxy would claim to allow persistence but not reuse the connection. + + + + + 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. + + + + + Fixed a crash on some Windows versions when header randomization + is enabled and the date couldn't be parsed. + + + + + Privoxy's keep-alive timeout for the current connection is reduced + to the one specified in the client's Keep-Alive header. + + + + + For HTTP/1.1 requests, Privoxy implies keep-alive support by not + setting any Connection header instead of using 'Connection: keep-alive'. + + + + + If the socket isn't reusable, Privoxy doesn't temporarily waste + a socket slot to remember the connection. + + + + + If keep-alive support is disabled but compiled in, the client's + Keep-Alive header is removed. + + + + + Fixed a bug on mingw32 where downloading large files failed if + keep-alive support was enabled. + + + + + Fixed a bug that (at least theoretically) could cause log + timestamps to be occasionally off by about a second. + + + + + The configure script respects the $PATH variable when searching + for groups and id. + + + + + Compressed content with extra fields couldn't be decompressed + and would get passed to the client unfiltered. This problem + has only be detected through statical analysis with clang as + nobody seems to be using extra fields anyway. + + + + + If the server resets the Connection after sending only the headers + Privoxy forwards what it got to the client. Previously Privoxy + would deliver an error message instead. + + + + + Error messages in case of connection timeouts use the right + HTTP status code. + + + + + If spawning a child to handle a request fails, the client + gets an error message and Privoxy continues to listen for + new requests right away. + + + + + The error messages in case of server-connection timeouts or + prematurely closed server connections are now template-based. + + + + + If zlib support isn't compiled in, Privoxy no longer tries to + filter compressed content unless explicitly asked to do so. + + + + + In case of connections that are denied based on ACL directives, + the memory used for the client IP is no longer leaked. + + + + + Fixed another small memory leak if the client request times out + while waiting for client headers other than the request line. + + + + + The client socket is kept open until the server socket has + been marked as unused. This should increase the chances that + the still-open connection will be reused for the client's next + request to the same destination. Note that this only matters + if connection-sharing is enabled. + + + + + A TODO list has been added to the source tarball to give potential + volunteers a better idea of what the current goals are. Donations + are still welcome too: http://www.privoxy.org/faq/general.html#DONATE + + + + + 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. + + + + + More reliable detection of prematurely closed client sockets + with keep-alive enabled. + + + + + FEATURE_CONNECTION_KEEP_ALIVE is decoupled from + FEATURE_CONNECTION_SHARING and now available on + all platforms. + + + + + Improved handling of POST requests on reused connections. + Should fix problems with stalled connections after submitting + form data with some browser configurations. + + + + + Fixed various latency calculation issues. + + + + + Allows the client to pass NTLM authentication requests to a + forwarding proxy.
