-*** Version 3.0.17 Stable ***
-
-- 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 or the
- request timed out. Reported by "Karsten" in #3028326.
-- 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
- or the request timed out. 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.
-- 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.
-- 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.
-- 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.
-- 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.
-- 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.
-- Privoxy logs when reading an action, filter or trust file.
-- 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.
-
-- CGI interface improvements:
- - 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.
- - Apostrophes in block messages no longer cause parse errors
- when the blocked page is viewed with JavaScript enabled.
- Reported by dg1727 in #3062296.
- - Fix a bunch of anchors that used underscores instead of dashes.
- - Allow to keep the client connection alive after crunching the previous request.
- Already opened server connections can be kept alive, too.
- - In cgi_show_url_info(), don't forget to prefix URLs that only contain
- http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott.
- - Show the 404 CGI page if cgi_send_user_manual() is called while
- local user manual delivery is disabled.

+- Security/Reliability:
+ - Fixed memory leaks when a response is buffered and the buffer
+ limit is reached or Privoxy is running out of memory.

+ was enabled, Privoxy failed to get the request destination
+ from the Host header and a memory allocation failed.

+
+- General improvements:
+ - 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.

+ - Downgrade the 'Graceful termination requested' message
+ to LOG_LEVEL_INFO as it isn't an error.
+ Sponsored by: Robert Klemme
+ - 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.
+ - Comment out trusted-cgi-referer pointing to example.org.
