-> introduces IPv6 support,
- improved keep-alive support and a bunch of minor improvements:</P

-></P
-><UL
-><LI
-><P
-> Added IPv6 support. Thanks to Petr Pisar who not only provided
- the initial patch but also helped a lot with the integration.
- </P
-></LI
-><LI
-><P
-> Added client-side keep-alive support. This should also allow
- NTLM authentication through Privoxy, but this hasn't been
- confirmed yet.
- </P
-></LI
-><LI
-><P
-> The connection sharing code is only used if the connection-sharing
- option is enabled.
- </P
-></LI
-><LI
-><P
-> The max-client-connections option has been added to restrict
- the number of client connections below a value enforced by
- the operating system.
- </P
-></LI
-><LI
-><P
-> Fixed a regression reintroduced in 3.0.12 that could cause
- crashes on mingw32 if header date randomization was enabled.
- </P
-></LI
-><LI
-><P
-> 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.
- </P
-></LI
-><LI
-><P
-> 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.
- </P
-></LI
-><LI
-><P
-> Error messages in case of connection timeouts use the right
- HTTP status code.
- </P
-></LI
-><LI
-><P
-> 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.
- </P
-></LI
-><LI
-><P
-> The error messages in case of server-connection timeouts or
- prematurely closed server connections are now template-based.
- </P
-></LI
-><LI
-><P
-> If zlib support isn't compiled in, Privoxy no longer tries to
- filter compressed content unless explicitly asked to do so.
- </P
-></LI
-><LI
-><P
-> In case of connections that are denied based on ACL directives,
- the memory used for the client IP is no longer leaked.
- </P
-></LI
-><LI
-><P
-> Fixed another small memory leak if the client request times out
- while waiting for client headers other than the request line.
- </P
-></LI
-><LI
-><P
-> 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.
- </P
-></LI
-><LI
-><P
-> A TODO list has been added to the source tarballs 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

+ Release</a></h1>
+
+ <p><span class="APPLICATION">Privoxy 3.0.19</span> is a stable release.
+ The changes since 3.0.18 stable are:</p>
+
+ <ul>
+ <li>
+ <p>Bug fixes:</p>
+
+ <ul>
+ <li>
+ <p>Prevent a segmentation fault when de-chunking buffered
+ content. It could be triggered by malicious web servers if
+ Privoxy was configured to filter the content and running on a
+ platform where SIZE_T_MAX isn't larger than UINT_MAX, which
+ probably includes most 32-bit systems. On those platforms, all
+ Privoxy versions before 3.0.19 appear to be affected. To be on
+ the safe side, this bug should be presumed to allow code
+ execution as proving that it doesn't seems unrealistic.</p>
+ </li>
+
+ <li>
+ <p>Do not expect a response from the SOCKS4/4A server until it
+ got something to respond to. This regression was introduced in
+ 3.0.18 and prevented the SOCKS4/4A negotiation from working.
+ Reported by qqqqqw in #3459781.</p>
+ </li>
+ </ul>
+ </li>
+
+ <li>
+ <p>General improvements:</p>
+
+ <ul>
+ <li>
+ <p>Fix an off-by-one in an error message about connect
+ failures.</p>
+ </li>
+
+ <li>
+ <p>Use a GNUMakefile variable for the webserver root directory
+ and update the path. Sourceforge changed it which broke various
+ web-related targets.</p>
+ </li>
+
+ <li>
+ <p>Update the CODE_STATUS description.</p>
+ </li>
+ </ul>
+ </li>
+ </ul>
+
+ <p>The following changes were made between 3.0.17 and 3.0.18:</p>
+
+ <ul>
+ <li>
+ <p>Bug fixes:</p>
+
+ <ul>
+ <li>
+ <p>If a generated redirect URL contains characters RFC 3986
+ doesn't permit, they are (re)encoded. Not doing this makes
+ Privoxy versions from 3.0.5 to 3.0.17 susceptible to HTTP
+ response splitting (CWE-113) attacks if the
+ +fast-redirects{check-decoded-url} action is used.</p>
+ </li>
+
+ <li>
+ <p>Fix a logic bug that could cause Privoxy to reuse a server
+ socket after it got tainted by a server-header-tagger-induced
+ block that was triggered before the whole server response had
+ been read. If keep-alive was enabled and the request following
+ the blocked one was to the same host and using the same
+ forwarding settings, Privoxy would send it on the tainted server
+ socket. While the server would simply treat it as a pipelined
+ request, Privoxy would later on fail to properly parse the
+ server's response as it would try to parse the unread data from
+ the first response as server headers for the second one.
+ Regression introduced in 3.0.17.</p>
+ </li>
+
+ <li>
+ <p>When implying keep-alive in client_connection(), remember that
+ the client didn't. Fixes a regression introduced in 3.0.13 that
+ would cause Privoxy to wait for additional client requests after
+ receiving a HTTP/1.1 request with "Connection: close" set and
+ connection sharing enabled. With clients which terminates the
+ client connection after detecting that the whole body has been
+ received it doesn't really matter, but with clients that don't
+ the connection would be kept open until it timed out.</p>
+ </li>
+
+ <li>
+ <p>Fix a subtle race condition between
+ prepare_csp_for_next_request() and sweep(). A thread preparing
+ itself for the next client request could briefly appear to be
+ inactive. If all other threads were already using more recent
+ files, the thread could get its files swept away under its feet.
+ So far this has only been reproduced while stress testing in
+ valgrind while touching action files in a loop. It's unlikely to
+ have caused any actual problems in the real world.</p>
+ </li>
+
+ <li>
+ <p>Disable filters if SDCH compression is used unless filtering
+ is forced. If SDCH was combined with a supported compression
+ algorithm, Privoxy previously could try to decompress it and
+ ditch the Content-Encoding header even though the SDCH
+ compression wasn't dealt with. Reported by zebul666 in
+ #3225863.</p>
+ </li>
+
+ <li>
+ <p>Make a copy of the --user value and only mess with that when
+ splitting user and group. On some operating systems modifying the
+ value directly is reflected in the output of ps and friends and
+ can be misleading. Reported by zepard in #3292710.</p>
+ </li>
+
+ <li>
+ <p>If forwarded-connect-retries is set, only retry if Privoxy is
+ actually forwarding the request. Previously direct connections
+ would be retried as well.</p>
+ </li>
+
+ <li>
+ <p>Fixed a small memory leak when retrying connections with IPv6
+ support enabled.</p>
+ </li>
+
+ <li>
+ <p>Remove an incorrect assertion in
+ compile_dynamic_pcrs_job_list() It could be triggered by a pcrs
+ job with an invalid pcre pattern (for example one that contains a
+ lone quantifier).</p>
+ </li>
+
+ <li>
+ <p>If the --user argument user[.group] contains a dot, always
+ bail out if no group has been specified. Previously the intended,
+ but undocumented (and apparently untested), behaviour was to try
+ interpreting the whole argument as user name, but the detection
+ was flawed and checked for '0' instead of '\0', thus merely
+ preventing group names beginning with a zero.</p>
+ </li>
+
+ <li>
+ <p>In html_code_map[], use a numeric character reference instead
+ of ' which wasn't standardized before XHTML 1.0.</p>
+ </li>
+
+ <li>
+ <p>Fix an invalid free when compiled with
+ FEATURE_GRACEFUL_TERMINATION and shut down through
+ http://config.privoxy.org/die</p>
+ </li>
+
+ <li>
+ <p>In get_actions(), fix the "temporary" backwards compatibility
+ hack to accept block actions without reason. It also covered
+ other actions that should be rejected as invalid. Reported by
+ Billy Crook.</p>
+ </li>
+ </ul>
+ </li>
+
+ <li>
+ <p>General improvements:</p>
+
+ <ul>
+ <li>
+ <p>Privoxy can (re)compress buffered content before delivering it
+ to the client. Disabled by default as most users wouldn't benefit
+ from it.</p>
+ </li>
+
+ <li>
+ <p>The +fast-redirects{check-decoded-url} action checks URL
+ segments separately. If there are other parameters behind the
+ redirect URL, this makes it unnecessary to cut them off by
+ additionally using a +redirect{} pcrs command. Initial patch
+ submitted by Jamie Zawinski in #3429848.</p>
+ </li>
+
+ <li>
+ <p>When loading action sections, verify that the referenced
+ filters exist. Currently missing filters only result in an error
+ message, but eventually the severity will be upgraded to
+ fatal.</p>
+ </li>
+
+ <li>
+ <p>Allow to bind to multiple separate addresses. Patch set
+ submitted by Petr Pisar in #3354485.</p>
+ </li>
+
+ <li>
+ <p>Set socket_error to errno if connecting fails in
+ rfc2553_connect_to(). Previously rejected direct connections
+ could be incorrectly reported as DNS issues if Privoxy was
+ compiled with IPv6 support.</p>
+ </li>
+
+ <li>
+ <p>Adjust url_code_map[] so spaces are replaced with %20 instead
+ of '+' While '+' can be used by client's submitting form data,
+ this is not actually what Privoxy is using the lookups for. This
+ is more of a cosmetic issue and doesn't fix any known
+ problems.</p>
+ </li>
+
+ <li>
+ <p>When compiled without FEATURE_FAST_REDIRECTS, do not silently
+ ignore +fast-redirect{} directives</p>
+ </li>
+
+ <li>
+ <p>Added a workaround for GNU libc's strptime() reporting
+ negative year values when the parsed year is only specified with
+ two digits. On affected systems cookies with such a date would
+ not be turned into session cookies by the +session-cookies-only
+ action. Reported by Vaeinoe in #3403560</p>
+ </li>
+
+ <li>
+ <p>Fixed bind failures with certain GNU libc versions if no
+ non-loopback IP address has been configured on the system. This
+ is mainly an issue if the system is using DHCP and Privoxy is
+ started before the network is completely configured. Reported by
+ Raphael Marichez in #3349356. Additional insight from Petr
+ Pisar.</p>
+ </li>
+
+ <li>
+ <p>Privoxy log messages now use the ISO 8601 date format
+ %Y-%m-%d. It's only slightly longer than the old format, but
+ contains the full date including the year and allows sorting by
+ date (when grepping in multiple log files) without hassle.</p>
+ </li>
+
+ <li>
+ <p>In get_last_url(), do not bother trying to decode URLs that do
+ not contain at least one '%' sign. It reduces the log noise and a
+ number of unnecessary memory allocations.</p>
+ </li>
+
+ <li>
+ <p>In case of SOCKS5 failures, dump the socks response in the log
+ message.</p>
+ </li>
+
+ <li>
+ <p>Simplify the signal setup in main().</p>
+ </li>
+
+ <li>
+ <p>Streamline socks5_connect() slightly.</p>
+ </li>
+
+ <li>
+ <p>In socks5_connect(), require a complete socks response from
+ the server. Previously Privoxy didn't care how much data the
+ server response contained as long as the first two bytes
+ contained the expected values. While at it, shrink the buffer
+ size so Privoxy can't read more than a whole socks response.</p>
+ </li>
+
+ <li>
+ <p>In chat(), do not bother to generate a client request in case
+ of direct CONNECT requests. It will not be used anyway.</p>
+ </li>
+
+ <li>
+ <p>Reduce server_last_modified()'s stack size.</p>
+ </li>
+
+ <li>
+ <p>Shorten get_http_time() by using strftime().</p>
+ </li>
+
+ <li>
+ <p>Constify the known_http_methods pointers in
+ unknown_method().</p>
+ </li>
+
+ <li>
+ <p>Constify the time_formats pointers in parse_header_time().</p>
+ </li>
+
+ <li>
+ <p>Constify the formerly_valid_actions pointers in
+ action_used_to_be_valid().</p>
+ </li>
+
+ <li>
+ <p>Introduce a GNUMakefile MAN_PAGE variable that defaults to
+ privoxy.1. The Debian package uses section 8 for the man page and
+ this should simplify the patch.</p>
+ </li>
+
+ <li>
+ <p>Deduplicate the INADDR_NONE definition for Solaris by moving
+ it to jbsockets.h</p>
+ </li>
+
+ <li>
+ <p>In block_url(), ditch the obsolete workaround for ancient
+ Netscape versions that supposedly couldn't properly deal with
+ status code 403.</p>
+ </li>
+
+ <li>
+ <p>Remove a useless NULL pointer check in load_trustfile().</p>
+ </li>
+
+ <li>
+ <p>Remove two useless NULL pointer checks in
+ load_one_re_filterfile().</p>
+ </li>
+
+ <li>
+ <p>Change url_code_map[] from an array of pointers to an array of
+ arrays It removes an unnecessary layer of indirection and on
+ 64bit system reduces the size of the binary a bit.</p>
+ </li>
+
+ <li>
+ <p>Fix various typos. Fixes taken from Debian's 29_typos.dpatch
+ by Roland Rosenfeld.</p>
+ </li>
+
+ <li>
+ <p>Add a dok-tidy GNUMakefile target to clean up the messy HTML
+ generated by the other dok targets.</p>
+ </li>
+
+ <li>
+ <p>GNUisms in the GNUMakefile have been removed.</p>
+ </li>
+
+ <li>
+ <p>Change the HTTP version in static responses to 1.1</p>
+ </li>
+
+ <li>
+ <p>Synced config.sub and config.guess with upstream
+ 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.</p>
+ </li>
+
+ <li>
+ <p>Add a dedicated function to parse the values of toggles.
+ Reduces duplicated code in load_config() and provides better
+ error handling. Invalid or missing toggle values are now a fatal
+ error instead of being silently ignored.</p>
+ </li>
+
+ <li>
+ <p>Terminate HTML lines in static error messages with \n instead
+ of \r\n.</p>
+ </li>
+
+ <li>
+ <p>Simplify cgi_error_unknown() a bit.</p>
+ </li>
+
+ <li>
+ <p>In LogPutString(), don't bother looking at pszText when not
+ actually logging anything.</p>
+ </li>
+
+ <li>
+ <p>Change ssplit()'s fourth parameter from int to size_t. Fixes a
+ clang complaint.</p>
+ </li>
+
+ <li>
+ <p>Add a warning that the statistics currently can't be trusted.
+ Mention Privoxy-Log-Parser's --statistics option as an
+ alternative for the time being.</p>
+ </li>
+
+ <li>
+ <p>In rfc2553_connect_to(), start setting cgi->error_message
+ on error.</p>
+ </li>
+
+ <li>
+ <p>Change the expected status code returned for http://p.p/die
+ depending on whether or not FEATURE_GRACEFUL_TERMINATION is
+ available.</p>
+ </li>
+
+ <li>
+ <p>In cgi_die(), mark the client connection for closing. If the
+ client will fetch the style sheet through another connection it
+ gets the main thread out of the accept() state and should thus
+ trigger the actual shutdown.</p>
+ </li>
+
+ <li>
+ <p>Add a proper CGI message for cgi_die().</p>
+ </li>
+
+ <li>
+ <p>Don't enforce a logical line length limit in
+ read_config_line().</p>
+ </li>
+
+ <li>
+ <p>Slightly refactor server_last_modified() to remove useless
+ gmtime*() calls.</p>
+ </li>
+
+ <li>
+ <p>In get_content_type(), also recognize '.jpeg' as JPEG
+ extension.</p>
+ </li>
+
+ <li>
+ <p>Add '.png' to the list of recognized file extensions in
+ get_content_type().</p>
+ </li>
+
+ <li>
+ <p>In block_url(), consistently use the block reason "Request
+ blocked by Privoxy" In two places the reason was "Request for
+ blocked URL" which hides the fact that the request got blocked by
+ Privoxy and isn't necessarily correct as the block may be due to
+ tags.</p>
+ </li>
+
+ <li>
+ <p>In listen_loop(), reload the configuration files after
+ accepting a new connection instead of before. Previously the
+ first connection that arrived after a configuration change would
+ still be handled with the old configuration.</p>
+ </li>
+
+ <li>
+ <p>In chat()'s receive-data loop, skip a client socket check if
+ the socket will be written to right away anyway. This can
+ increase the transfer speed for unfiltered content on fast
+ network connections.</p>
+ </li>
+
+ <li>
+ <p>The socket timeout is used for SOCKS negotiations as well
+ which previously couldn't timeout.</p>
+ </li>
+
+ <li>
+ <p>Don't keep the client connection alive if any configuration
+ file changed since the time the connection came in. This is
+ closer to Privoxy's behaviour before keep-alive support for
+ client connection has been added and also less confusing in
+ general.</p>
+ </li>
+
+ <li>
+ <p>Treat all Content-Type header values containing the pattern
+ 'script' as a sign of text. Reported by pribog in #3134970.</p>
+ </li>
+ </ul>
+ </li>
+
+ <li>
+ <p>Action file improvements:</p>
+
+ <ul>
+ <li>
+ <p>Moved the site-specific block pattern section below the one
+ for the generic patterns so for requests that are matched in
+ both, the block reason for the domain is shown which is usually
+ more useful than showing the one for the generic pattern.</p>
+ </li>
+
+ <li>
+ <p>Remove -prevent-compression from the fragile alias. It's no
+ longer used anywhere by default and isn't known to break stuff
+ anyway.</p>
+ </li>
+
+ <li>
+ <p>Add a (disabled) section to block various Facebook tracking
+ URLs. Reported by Dan Stahlke in #3421764.</p>
+ </li>
+
+ <li>
+ <p>Add a (disabled) section to rewrite and redirect
+ click-tracking URLs used on news.google.com. Reported by Dan
+ Stahlke in #3421755.</p>
+ </li>
+
+ <li>
+ <p>Unblock linuxcounter.net/. Reported by Dan Stahlke in
+ #3422612.</p>
+ </li>
+
+ <li>
+ <p>Block 'www91.intel.com/' which is used by Omniture. Reported
+ by Adam Piggott in #3167370.</p>
+ </li>
+
+ <li>
+ <p>Disable the handle-as-empty-doc-returns-ok option and mark it
+ as deprecated. Reminded by tceverling in #2790091.</p>
+ </li>
+
+ <li>
+ <p>Add ".ivwbox.de/" to the "Cross-site user tracking" section.
+ Reported by Nettozahler in #3172525.</p>
+ </li>
+
+ <li>
+ <p>Unblock and fast-redirect ".awin1.com/.*=http://". Reported by
+ Adam Piggott in #3170921.</p>
+ </li>
+
+ <li>
+ <p>Block "b.collective-media.net/".</p>
+ </li>
+
+ <li>
+ <p>Widen the Debian popcon exception to "qa.debian.org/popcon".
+ Seen in Debian's 05_default_action.dpatch by Roland
+ Rosenfeld.</p>
+ </li>
+
+ <li>
+ <p>Block ".gemius.pl/" which only seems to be used for user
+ tracking. Reported by johnd16 in #3002731. Additional input from
+ Lee and movax.</p>
+ </li>
+
+ <li>
+ <p>Disable banners-by-size filters for '.thinkgeek.com/'. The
+ filter only seems to catch pictures of the inventory.</p>
+ </li>
+
+ <li>
+ <p>Block requests for 'go.idmnet.bbelements.com/please/showit/'.
+ Reported by kacperdominik in #3372959.</p>
+ </li>
+
+ <li>
+ <p>Unblock adainitiative.org/.</p>
+ </li>
+
+ <li>
+ <p>Add a fast-redirects exception for
+ '.googleusercontent.com/.*=cache'.</p>
+ </li>
+
+ <li>
+ <p>Add a fast-redirects exception for
+ webcache.googleusercontent.com/.</p>

+ http://adassier.files.wordpress.com/.</p>
+ </li>
+ </ul>
+ </li>
+
+ <li>
+ <p>Filter file improvements:</p>
+
+ <ul>
+ <li>
+ <p>Let the yahoo filter hide '.ads'.</p>
+ </li>
+
+ <li>
+ <p>Let the msn filter hide overlay ads for Facebook 'likes' in
+ search results and elements with the id 's_notf_div'. They only
+ seem to be used to advertise site 'enhancements'.</p>
+ </li>
+
+ <li>
+ <p>Let the js-events filter additionally disarm setInterval().
+ Suggested by dg1727 in #3423775.</p>
+ </li>
+ </ul>
+ </li>
+
+ <li>
+ <p>Documentation improvements:</p>
+
+ <ul>
+ <li>
+ <p>Clarify the effect of compiling Privoxy with zlib support.
+ Suggested by dg1727 in #3423782.</p>
+ </li>
+
+ <li>
+ <p>Point out that the SourceForge messaging system works like a
+ black hole and should thus not be used to contact individual
+ developers.</p>
+ </li>
+
+ <li>
+ <p>Mention some of the problems one can experience when not
+ explicitly configuring an IP addresses as listen address.</p>
+ </li>
+
+ <li>
+ <p>Explicitly mention that hostnames can be used instead of IP
+ addresses for the listen-address, that only the first address
+ returned will be used and what happens if the address is invalid.
+ Requested by Calestyo in #3302213.</p>
+ </li>
+ </ul>
+ </li>
+
+ <li>
+ <p>Log message improvements:</p>
+
+ <ul>
+ <li>
+ <p>If only the server connection is kept alive, do not pretend to
+ wait for a new client request.</p>
+ </li>
+
+ <li>
+ <p>Remove a superfluous log message in forget_connection().</p>
+ </li>
+
+ <li>
+ <p>In chat(), properly report missing server responses as such
+ instead of calling them empty.</p>
+ </li>
+
+ <li>
+ <p>In forwarded_connect(), fix a log message nobody should ever
+ see.</p>
+ </li>
+
+ <li>
+ <p>Fix a log message in socks5_connect(), a failed write
+ operation was logged as failed read operation.</p>
+ </li>
+
+ <li>
+ <p>Let load_one_actions_file() properly complain about a missing
+ '{' at the beginning of the file. Simply stating that a line is
+ invalid isn't particularly helpful.</p>
+ </li>
+
+ <li>
+ <p>Do not claim to listen on a socket until Privoxy actually
+ does. Patch submitted by Petr Pisar #3354485</p>
+ </li>
+
+ <li>
+ <p>Prevent a duplicated LOG_LEVEL_CLF message when sending out
+ the "no-server-data" response.</p>
+ </li>
+
+ <li>
+ <p>Also log the client socket when dropping a connection.</p>
+ </li>
+
+ <li>
+ <p>Include the destination host in the 'Request ... marked for
+ blocking. limit-connect{...} doesn't allow CONNECT ...' message
+ Patch submitted by Saperski in #3296250.</p>
+ </li>
+
+ <li>
+ <p>Prevent a duplicated log message if none of the resolved IP
+ addresses were reachable.</p>
+ </li>
+
+ <li>
+ <p>In connect_to(), do not pretend to retry if
+ forwarded-connect-retries is zero or unset.</p>
+ </li>
+
+ <li>
+ <p>When a specified user or group can't be found, put the name in
+ single-quotes when logging it.</p>
+ </li>
+
+ <li>
+ <p>In rfc2553_connect_to(), explain getnameinfo() errors
+ better.</p>
+ </li>
+
+ <li>
+ <p>Remove a useless log message in chat().</p>
+ </li>
+
+ <li>
+ <p>When retrying to connect, also log the maximum number of
+ connection attempts.</p>
+ </li>
+
+ <li>
+ <p>Rephrase a log message in compile_dynamic_pcrs_job_list().
+ Divide the error code and its meaning with a colon. Call the pcrs
+ job dynamic and not the filter. Filters may contain dynamic and
+ non-dynamic pcrs jobs at the same time. Only mention the name of
+ the filter or tagger, but don't claim it's a filter when it could
+ be a tagger.</p>
+ </li>
+
+ <li>
+ <p>In a fatal error message in load_one_actions_file(), cover
+ both URL and TAG patterns.</p>
+ </li>
+
+ <li>
+ <p>In pcrs_strerror(), properly report unknown positive error
+ code values as such. Previously they were handled like 0 (no
+ error).</p>
+ </li>
+
+ <li>
+ <p>In compile_dynamic_pcrs_job_list(), also log the actual error
+ code as pcrs_strerror() doesn't handle all errors reported by
+ pcre.</p>
+ </li>
+
+ <li>
+ <p>Don't bother trying to continue chatting if the client didn't
+ ask for it. Reduces log noise a bit.</p>
+ </li>
+
+ <li>
+ <p>Make two fatal error message in load_one_actions_file() more
+ descriptive.</p>
+ </li>
+
+ <li>
+ <p>In cgi_send_user_manual(), log when rejecting a file name due
+ to '/' or '..'.</p>
+ </li>
+
+ <li>
+ <p>In load_file(), log a message if opening a file failed. The
+ CGI error message alone isn't too helpful.</p>
+ </li>
+
+ <li>
+ <p>In connection_destination_matches(), improve two log messages
+ to help understand why the destinations don't match.</p>
+ </li>
+
+ <li>
+ <p>Rephrase a log message in serve(). Client request arrival
+ should be differentiated from closed client connections now.</p>
+ </li>
+
+ <li>
+ <p>In serve(), log if a client connection isn't reused due to a
+ configuration file change.</p>
+ </li>
+
+ <li>
+ <p>Let mark_server_socket_tainted() always mark the server socket
+ tainted, just don't talk about it in cases where it has no
+ effect. It doesn't change Privoxy's behaviour, but makes
+ understanding the log file easier.</p>
+ </li>
+ </ul>
+ </li>
+
+ <li>
+ <p>configure:</p>
+

+ <li>

+ <li>
+ <p>Do not check for the existence of strerror() and memmove()
+ twice</p>
+ </li>
+
+ <li>
+ <p>Remove a useless test for setpgrp(2). Privoxy doesn't need it
+ and it can cause problems when cross-compiling.</p>

+ to Upgraders</a></h2>
+
+ <p>A quick list of things to be aware of before upgrading from earlier
+ versions of <span class="APPLICATION">Privoxy</span>:</p>
+
+ <ul>
+ <li>
+ <p>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>.</p>
+
+ <p>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.</p>
+ </li>
+
+ <li>
+ <p>Note that some installers remove earlier versions completely,
+ including configuration files, therefore you should really save any
+ important configuration files!</p>
+ </li>
+
+ <li>
+ <p>On the other hand, other installers don't overwrite existing
+ configuration files, thinking you will want to do that
+ yourself.</p>
+ </li>
+
+ <li>
+ <p><tt class="FILENAME">standard.action</tt> has been merged into
+ the <tt class="FILENAME">default.action</tt> file.</p>
+ </li>
+
+ <li>
+ <p>In the default configuration only fatal errors are logged now.
+ You can change that in the <a href="config.html#DEBUG">debug
+ section</a> of the configuration file. You may also want to enable
+ more verbose logging until you verified that the new <span class=
+ "APPLICATION">Privoxy</span> version is working as expected.</p>
+ </li>
+
+ <li>
+ <p>Three other config file settings are now off by default:
+ <a href="config.html#ENABLE-REMOTE-TOGGLE">enable-remote-toggle</a>,
+ <a href=
+ "config.html#ENABLE-REMOTE-HTTP-TOGGLE">enable-remote-http-toggle</a>,
+ and <a href=
+ "config.html#ENABLE-EDIT-ACTIONS">enable-edit-actions</a>. If you
+ use or want these, you will need to explicitly enable them, and be
+ aware of the security issues involved.</p>
