- - Privoxy can (re)compress buffered content before delivering
- it to the client. Disabled by default as most users wouldn't
- benefit from it.
- - 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.
- - 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.
- - Allow to bind to multiple separate addresses.
- Patch set submitted by Petr Pisar in #3354485.
- - 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.
- - 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.
- - When compiled without FEATURE_FAST_REDIRECTS, do not silently
- ignore +fast-redirect{} directives
- - 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
- - 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.
- - 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.
- - 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.
- - In case of SOCKS5 failures, dump the socks response in the log message.
- - Simplify the signal setup in main().
- - Streamline socks5_connect() slightly.
- - 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.
- - In chat(), do not bother to generate a client request in case of
- direct CONNECT requests. It will not be used anyway.
- - Reduce server_last_modified()'s stack size.
- - Shorten get_http_time() by using strftime().
- - Constify the known_http_methods pointers in unknown_method().
- - Constify the time_formats pointers in parse_header_time().
- - Constify the formerly_valid_actions pointers in action_used_to_be_valid().
- - 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.
- - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
- - In block_url(), ditch the obsolete workaround for ancient Netscape versions
- that supposedly couldn't properly deal with status code 403.
- - Remove a useless NULL pointer check in load_trustfile().
- - Remove two useless NULL pointer checks in load_one_re_filterfile().
- - 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.
- - Fix various typos. Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
- - Add a dok-tidy GNUMakefile target to clean up the messy HTML
- generated by the other dok targets.
- - GNUisms in the GNUMakefile have been removed.
- - Change the HTTP version in static responses to 1.1
- - Synced config.sub and config.guess with upstream
- 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
- - 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.
- - Terminate HTML lines in static error messages with \n instead of \r\n.
- - Simplify cgi_error_unknown() a bit.
- - In LogPutString(), don't bother looking at pszText when not
- actually logging anything.
- - Change ssplit()'s fourth parameter from int to size_t.
- Fixes a clang complaint.
- - 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.
- - In rfc2553_connect_to(), start setting cgi->error_message on error.
- - Change the expected status code returned for http://p.p/die depending
- on whether or not FEATURE_GRACEFUL_TERMINATION is available.
- - 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.
- - Add a proper CGI message for cgi_die().
- - Don't enforce a logical line length limit in read_config_line().
- - Slightly refactor server_last_modified() to remove useless gmtime*() calls.
- - In get_content_type(), also recognize '.jpeg' as JPEG extension.
- - Add '.png' to the list of recognized file extensions in get_content_type().
- - 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.
- - 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.
- - 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.
- - The socket timeout is used for SOCKS negotiations as well which
- previously couldn't timeout.
- - 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.
- - Treat all Content-Type header values containing the pattern
- 'script' as a sign of text. Reported by pribog in #3134970.
+ - Added experimental https inspection support which allows to filter
+ https traffic. To enable it, install MbedTLS and configure with
+ --with-mbedtls, or install OpenSSL or LibreSSL and configure
+ with --with-openssl.
+ Afterwards configure the directives in section 7 of the
+ config file and enable the +https-inspection action.
+ Initial MbedTLS-based code contributed by Vaclav Svec,
+ initial OpenSSL support contributed by Maxim Antonov.
+ With help from Nedzad Hrnjica and Ho+ Ho+ Ho+.
+ Integration and improvements sponsored by Robert Klemme.
+ - pcrs: Request JIT compilation if it's supported and
+ the filter isn't dynamic. This can speed up filtering.
+ - Added support for Brotli decompression.
+ Sponsored by: Robert Klemme
+ - Added FEATURE_EXTENDED_STATISTICS to gather statistics for
+ block reasons and filter executions. To enable it, configure
+ with --enable-extended-statistics and visit
+ http://config.privoxy.org/show-status.
+ Sponsored by: Robert Klemme
+ - Use the IP_FREEBIND socket option, if defined. This allows
+ Privoxy to bind to not-yet assigned IP addresses which is
+ useful in failover environments.
+ Patch by Sam Varshavchik.
+ - Allow to use extended host patterns and vanilla host patterns
+ at the same time by prefixing extended host patterns with
+ "PCRE-HOST-PATTERN:". To enable this, configure with
+ --enable-pcre-host-patterns.
+ Sponsored by: Robert Klemme
+ - Added "Cross-origin resource sharing" (CORS) support.
+ This allows to access Privoxy's CGI interface via JavaScript from
+ another domain (white-listed with the new cors-allowed-origin directive).
+ Based on a patch by Nedzad Hrnjica.
+ Sponsored by: Robert Klemme.
+ - Add SOCKS5 username/password support.
+ Based on a patch by Sam, improved by Ivan Romanov.
+ Closes Patch#141 and solves TODO#105.
+ - Bump the maximum number of action and filter files
+ to 100 each.
+ Sponsored by: Robert Klemme
+ - Fixed handling of filters with "split-large-forms 1"
+ when using the CGI editor.
+ Reported by withoutname in #921.
+ - Better detect a mismatch of connection details when
+ figuring out whether or not a connection can be reused.
+ - Don't send a "Connection failure" message instead of the
+ "DNS failure" message.
+ Sponsored by: Robert Klemme
+ - Let LOG_LEVEL_REQUEST log all requests. Previously unencrypted
+ requests were only logged with LOG_LEVEL_REQUEST when they weren't
+ crunched (in which case they were logged with LOG_LEVEL_CRUNCH).
+ This was documented behaviour, but logging all requests seems more useful.
+ - Fixed locking around localtime() and gmtime().
+ - Removed OS/2 support. We haven't provided OS/2 packages in years,
+ it complicated the code and it depended on a fallback snprintf()
+ implementation which is GPLv2 only.
+ - Remove the fallback snprintf() implementation
+ Now that OS/2 support is gone we no longer need it.
+ - Fixed a bunch of format specifiers log messages.
+ - Added a missing apostrophe in the 'More Privoxy' menu.
+ - Explicitly prevent use of FEATURE_CONNECTION_SHARING
+ without FEATURE_CONNECTION_KEEP_ALIVE. It makes no sense
+ and does not compile anyway.
+ Sponsored by: Robert Klemme
+ - Fix build without FEATURE_CONNECTION_KEEP_ALIVE.

+ to LOG_LEVEL_INFO as it isn't an error.

+ - decompress_iob(): Downgrade the no-content message to LOG_LEVEL_RE_FILTER
+ While at it, fix a typo in a comment.
+ Sponsored by: Robert Klemme
+ - Fixed a couple of cppcheck warnings.
+ - Rename LOG_LEVEL_GPC to LOG_LEVEL_REQUEST.
+ Only the shadow knows what "GPC" is supposed to stand for.
+ - Remove SourceForge references in copyright headers.
+ - Upgrade a bunch of links to the homepage to https://.
+ - Add 'no-brotli-accepted' filter which prevents the
+ use of Brotli compression.
+ - Changed license for pcrs to GPLv2+ after getting the
+ permission from Andreas. This allows to redistribute
+ Privoxy under the GPLv3 which is required when linking
+ to future mbedTLS versions which are expected to be
+ licensed under the Apache 2.0 license only.
+ - Updated a bunch of tests that have to expect status code 403
+ now after r1.168/070e904afa5.
+ - Lowercase the host name in the request line.
+ - Only set SOURCE_DATE_EPOCH if it's not already set so
+ distributions can overwrite it through the environment.
+
+- Documentation changes:
+ - Explain that Privoxy has to be distributed under the
+ GPLv3 (or later) when linked with an MbedTLS version
+ that is licensed under the Apache 2.0 license.
+ - Import the GNU GPLv3 and include it the user manual.
+ - Clarify FEATURE_FORCE_LOAD's description. It allows to bypass
+ blocking not filtering and only does it if blocks aren't enforced.
+ Reported by: Robert Klemme
+ - FAQ: Remove Zwiebelfreunde e.V. from the list of fiduciary sponsors
+ As of 2021 they no longer handle donations for foreign organisations
+ due to lack of resources.
+ - FAQ: Remove an obsolete comment with a link to the long-gone PDF manual.
+ - FAQ: Add a link to the TODO list.
+ - FAQ: Change the sponsor amounts to USD slightly rounding the
+ converted amounts up to get simple numbers.
+ Receiving USD is apparently easier for SPI and SPI is
+ preferred by sponsors as they can send invoices.
+ - Advertise the client-tags CGI page in the user manual.
+ - Stop advertising the show-version CGI page which no longer exists.
+ - Add yet another reason why +prevent-compression may cause problems.
+ - Don't claim that contributors need ssh. It's only needed for committers.
+ - Replace obsolete CVS instructions with Git instructions.
+ - Remove an obsolete comment
+
+- Config file changes:
+ - Change the suggested default-server-timeout to 5 to match the
+ suggested keep-alive-timeout. Otherwise using the defaults would
+ result in Privoxy reducing the default-server-timeout and logging
+ an error message.
+ Sponsored by: Robert Klemme
+ - Update the 'debug 1' description.
+ - Add a missing 'client-specific-tag' directive.
