+- Bug fixes:
+ - Improve the handling of chunk-encoded responses by buffering the data
+ even if filters are disabled and properly keeping track of where the
+ various chunks are supposed to start and end. Previously Privoxy would
+ merely check the last bytes received to see if they looked like the
+ last-chunk. This failed to work if the last-chunk wasn't received in one
+ read and could also result in actual data being misdetected
+ as last-chunk.
+ Should fix: SF support request #1739.
+ Reported by: withoutname.
+ - remove_chunked_transfer_coding(): Refuse to de-chunk invalid data
+ Previously the data could get corrupted even further.
+ Now we simply pass the unmodified data to the client.
+ - gif_deanimate(): Tolerate multiple image extensions in a row.
+ This allows to deanimate all the gifs on:
+ https://commons.wikimedia.org/wiki/Category:Animated_smilies
+ Fixes SF bug #795 reported by Celejar.
+ - OpenSSL generate_host_certificate(): Use X509_get_subject_name()
+ instead of X509_get_issuer_name() to get the issuer for generated
+ website certificates so there are no warnings in the browser when using
+ an intermediate CA certificate instead of a self-signed root certificate.
+ Problem reported and patch submitted by Chakib Benziane.
+ - can_filter_request_body(): Fix a log message that contained a spurious u.
+ - handle_established_connection(): Check for pending TLS data from the client
+ before checking if data is available on the connection.
+ The TLS library may have already consumed all the data from the client
+ response in which case poll() and select() will not detect that data is
+ available to be read.
+ Sponsored by: Robert Klemme.
+ - ssl_send_certificate_error(): Don't crash if there's no certificate
+ information available. This is only relevant when Privoxy is built with
+ wolfSSL 5.0.0 or later (code not yet published). Earlier wolfSSL versions
+ or the other TLS backends don't seem to trigger the crash.
+ - socks5_connect(): Add support for target hosts specified as IPv4 address
+ Previously the IP address was sent as domain.
- 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.
+ - Add a client-body-tagger action which creates tags based on
+ the content of the request body.
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.
- Sponsored by: Robert Klemme
- - 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.
+ - When client-body filters are enabled, buffer the whole request
+ before opening a connection to the server.
+ Makes it less likely that the server connection times out
+ and we don't open a connection if the buffering fails anyway.
+ Sponsored by: Robert Klemme.
+ - Add periods to a couple of log messages.
+ - accept_connection(): Add missing space to a log message.
+ - Initialize ca-related defaults with strdup_or_die() so errors
+ aren't silently ignored.
+ - make_path: Use malloc_or_die() in cases where allocation errors
+ were already fatal anyway.
+ - handle_established_connection(): Improve an error message slightly.
+ - receive_client_request(): Reject https URLs without CONNECT request.
+ - Include all requests in the statistics if mutexes are available.
+ Previously in case of reused connections only the last request got
+ counted. The statistics still aren't perfect but it's an improvement.
+ - Add read_socks_reply() and start using it in socks5_connect()
+ to apply the socket timeout more consistently.
+ - socks5_connect(): Deal with domain names in the socks reply
+ - Add a filter for bundeswehr.de that hides the cookie and
+ privacy info banner.

- Privoxy-Log-Parser:
- - Added a --keep-date option to keep the date in highlighted messages.
- - Highlight new log messages.
- - Make gather_loglevel_clf_stats() more tolerant. While at it,
- count all CLF messages as requests, even if the request is invalid.
- - Only show HTTP version distribution if at least one version has been detected.
- - Only show crunch statistics if crunches were detected.
- - Warn if the request counts differ.
- - Generate statistics if the log only contains LOG_LEVEL_CLF messages
- so it can be used with vanilla webserver logs.
- Previously Privoxy-specific "Request:" messages were required.
- - Align the client-HTTP-version distribution like other distributions
- - Bump version to 0.9.1
- - Include status code distribution in the stats.
- - Let the statistics include the size of the content Privoxy
- transferred excluding HTTP headers.
- - Get with the program and expect all requests to be logged with LOG_LEVEL_REQUEST.
- It's no longer necessary to count both LOG_LEVEL_REQUEST and
- LOG_LEVEL_CRUNCH messages to get the total number of requests.
- - Leverage the LOG_LEVEL_CLF message to gather statistics that where
- previously taken from LOG_LEVEL_HEADER lines. This results in less
- confusing results if https inspection is enabled in which case there
- are two LOG_LEVEL_HEADER lines with request lines.
- Sponsored by: Robert Klemme
- - Properly highlight the filter results message. Previously a brace got lost.
- - Prefer the number of CLF lines to get the total number of requests
- as it works with older Privoxy versions as well.
-
-- Privoxy-Regression-Test:
- - Turn curl's globbing mode off so we can allow more characters in URLs.
- - Allow '[' and ']' in URLs.
- - Include the action file when complaining about missing Sticky Actions.
- - Fix a sentence in the documentation.
- - Bump version to 0.7.1
-
-- url-pattern-translator:
- - Detect a couple of pattern prefixes case-insensitively.
- Sponsored by: Robert Klemme

- It should now be safe to "convert" a file multiple times.
- Sponsored by: Robert Klemme
- - Add the new 'PCRE-HOST-PATTERN:' prefix.
- Sponsored by: Robert Klemme
-
+ - Bump version to 0.9.5.
+ - Highlight more log messages.
+ - Highlight the Crunch reason only once. Previously the "crunch reason"
+ could also be highlighted when the URL contained a matching string.
+ The real crunch reason only occurs once per line, so there's no need
+ to continue looking for it after it has been found once.
+ While at it, add a comment with an example log line.
+
+- uagen:
+ - Bump version to 1.2.4.
+ - Update BROWSER_VERSION and BROWSER_REVISION to 102.0
+ to match the User-Agent of the current Firefox ESR.
+ - Explicitly document that changing the 'Gecko token' is suspicious.
+ - Consistently use a lower-case 'c' as copyright symbol.
+ - Bump copyright.
+ - Add 'aarch64' as Linux architecture.
+ - Add OpenBSD architecture 'arm64'.
+ - Stop using sparc64 as FreeBSD architecture.
+ It hasn't been supported for a while now.
+
+- Build system:
+ - Makefile: Add a 'dok' target that depends on the 'error' target
+ to show the "You are not using GNU make or did nor run configure"
+ message.
+ - configure: Fix --with-msan option.
+ Also (probably) reported by Andrew Savchenko.
+
+- macOS build system:
+ - Enable HTTPS inspection when building the macOS binary
+ (using OpenSSL as TLS library).
+
+- Documentation:
+ - Add OpenSSL to the list of libraries that may be licensed under the
+ Apache 2.0 license in which case the linked Privoxy binary has to be
+ distributed under the GPLv3 or later.
+ - config: Fix the documented ca-directory default value.
+ Reported by avoidr.
+ - Rebuild developer-manual and tidy with 'HTML Tidy for FreeBSD version 5.8.0'.
+ - Update developer manual with new macOS packaging instructions.
+ - Note that the FreeBSD installation instructions work for
+ ElectroBSD as well.
+ - Note that FreeBSD/ElectroBSD users can try to install Privoxy
+ as binary package using 'pkg'.
