- - 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.

- - 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.

- - 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.

- - 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.

- - 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.

- - 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.

- - Update the 'debug 1' description.
- - Add a missing 'client-specific-tag' directive.
- - Comment out trusted-cgi-referer pointing to example.org.
+ - Allow to edit the add-header action through the CGI editor by
+ generalizing the code that got added with the suppress-tag action.
+ Closes SF patch request #146. Patch by Maxim Antonov.
+ - Add a CGI handler for /wpad.dat that returns a
+ Proxy Auto-Configuration (PAC) file.
+ Among other things, it can be used to instruct clients
+ through DHCP to use Privoxy as proxy.
+ For example with the dnsmasq option:
+ dhcp-option=252,http://config.privoxy.org/wpad.dat
+ Initial patch by Richard Schneidt.
+ - Don't log the applied actions in process_encrypted_request()
+ Log them in continue_https_chat() instead to mirror chat().
+ Prevents the applied actions from getting logged twice
+ for the first request on an https-inspected connection.
+ - OpenSSL generate_host_certificate(): Use config.privoxy.org as Common Name
+ Org and Org Unit if the real host name is too long to get accepted by OpenSSL.
+ Clients should only care about the Subject Alternative Name
+ anyway and we can continue to use the real host name for it.
+ Reported by Miles Wen on privoxy-users@.
+ - Establish the TLS connection with the client earlier and decide
+ how to route the request afterwards. This allows to change the
+ forwarding settings based on information from the https-inspected
+ request, for example the path.
+ - listen_loop(): When shutting down gracefully, close listening ports
+ before waiting for the threads to exit. Allows to start a second
+ Privoxy with the same config file while the first Privoxy is still
+ running.
+ - serve(): Close the client socket as well if the server socket
+ for an inspected connection has been closed. Privoxy currently
+ can't establish a new server connection when the client socket
+ is reused and would drop the connection in continue_https_chat()
+ anyway.
+ - Don't disable redirect checkers in redirect_url().
+ Disable them in handle_established_connection() instead.
+ Doing it in redirect_url() prevented the +redirect{} and
+ +fast-redirects{} actions from being logged with LOG_LEVEL_ACTIONS.
+ - handle_established_connection(): Slightly improve a comment.
+ - handle_established_connection(): Fix a comment.
+ - socks5_connect(): Fix indentation.
+ - handle_established_connection(): Improve an error message.
+ - create_pattern_spec(): Fix ifdef indentation.
+ - Fix comment typos.
+ - process_encrypted_request(): Improve a log message.
+ The function only processes request headers and there
+ may still be unread request body data left to process.
+ - chat(): Log the applied actions before deciding how to forward the request.
+ - parse_time_header(): Silence a coverity complaint when building without assertions.
+ - receive_encrypted_request_headers(): Improve a log message.
+ - mbedTLS get_ciphersuites_from_string(): Use strlcpy() instead of strncpy().
+ Previously the terminating NUL wasn't copied which resulted
+ in a compiler warning. This didn't cause actual problems as
+ the target buffer was initialized by zalloc_or_die() so the
+ last byte of the target buffer was NUL already.
+ Actually copying the terminating NUL seems clearer, though.
+ - Remove compiler warnings. "log_error(LOG_LEVEL_FATAL, ..."
+ doesn't return but apparently the compiler doesn't know that.
+ Get rid of several "this statement may fall through
+ [-Wimplicit-fallthrough=]" warnings.
+ - Store the PEM certificate in a dynamically allocated buffer
+ when https-inspecting. Should prevent errors like:
+ 2021-03-16 22:36:19.148 7f47bbfff700 Error: X509 PEM cert len 16694 is larger than buffer len 16383
+ As a bonus it should slightly reduce the memory usage as most
+ certificates are smaller than the previously used fixed buffer.
