Privoxy 3.0.26 stable is a bug-fix release - for the previously released 3.0.25 beta which introduced client-specific - tags and included a couple of minor improvements.
Bug fixes: -
Fixed crashes with "listen-addr :8118" (SF Bug #902). - The regression was introduced in 3.0.25 beta and reported - by Marvin Renich in Debian bug #834941. -
General improvements: -
Log when privoxy is toggled on or off via cgi interface. -
Highlight the "Info: Now toggled " on/off log message - in the Windows log viewer. -
Highlight the loading actions/filter file log message - in the Windows log viewer. -
Mention client-specific tags on the toggle page as a - potentionally more appropriate alternative. -
Documentation improvements: -
Update download section on the homepage. - The downloads are available from the website now. -
Add sponsor FAQ. -
Remove obsolete reference to mailing lists hosted at SourceForge. -
Update the "Before the Release" section of the developer manual. -
Infrastructure improvements: -
Add perl script to generate an RSS feed for the packages - Submitted by "Unknown". -
Build system improvements: -
strptime.h: fix a compiler warning about ambiguous else. -
configure.in: Check for Docbook goo on the BSDs as well. -
GNUMakefile.in: Let the dok-user target remove temporary files. -
Changes between Privoxy 3.0.25 beta - and the previous release:
Bug fixes: -
Always use the current toggle state for new requests. - Previously new requests on reused connections inherited - the toggle state from the previous request even though - the toggle state could have changed. - Reported by Robert Klemme. -
Fixed two buffer-overflows in the (deprecated) static - pcre code. These bugs are not considered security issues - as the input is trusted. - Found with afl-fuzz and ASAN. -
General improvements: -
Added support for client-specific tags which allow Privoxy - admins to pre-define tags that are set for all requests from - clients that previously opted in through the CGI interface. - They are useful in multi-user setups where admins may - want to allow users to disable certain actions and filters - for themselves without affecting others. - In single-user setups they are useful to allow more fine-grained - toggling. For example to disable request blocking while still - crunching cookies, or to disable experimental filters only. - This is an experimental feature, the syntax and behaviour may - change in future versions. - Sponsored by Robert Klemme. -
Dynamic filters and taggers now support a $listen-address variable - which contains the address the request came in on. - For external filters the variable is called $PRIVOXY_LISTEN_ADDRESS. - Original patch contributed by pursievro. -
Add client-header-tagger 'listen-address'. -
Include the listen-address in the log message when logging new requests. - Patch contributed by pursievro. -
Turn invalid max-client-connections values into fatal errors. -
The show-status page now shows whether or not dates before 1970 - and after 2038 are expected to be handled properly. - This is mainly useful for Privoxy-Regression-Test but could - also come handy when dealing with time-related support requests. -
On Mac OS X the thread id in log messages are more likely to - be unique now. -
When complaining about missing filters, the filter type is logged - as well. -
A couple of harmless coverity warnings were silenced - (CID #161202, CID #161203, CID #161211). -
Action file improvements: -
Filtering is disabled for Range requests to let download resumption - and Windows updates work with the default configuration. -
Unblock ".ardmediathek.de/". - Reported by ThTomate in #932. -
Documentation improvements: -
Add FAQ entry for crashes caused by memory limits. -
Remove obsolete FAQ entry about a bug in PHP 4.2.3. -
Mention the new mailing lists were appropriate. - As the archives have not been migrated, continue to - mention the archives at SF in the contacting section - for now. -
Note that the templates should be adjusted if Privoxy is - running as intercepting proxy without getting all requests. -
A bunch of links were converted to https://. -
Rephrase onion service paragraph to make it more obvious - that Tor is involved and that the whole website (and not - just the homepage) is available as onion service. -
Streamline the "More information" section on the homepage further - by additionally ditching the link to the 'See also' section - of the user manual. The section contains mostly links that are - directly reachable from the homepage already and the rest is - not significant enough to get a link from the homepage. -
Change the add-header{} example to set the DNT header - and use a complete section to make copy and pasting - more convenient. - Add a comment to make it obvious that adding the - header is not recommended for obvious reasons. - Using the DNT header as example was suggested by - Leo Wzukw. -
Streamline the support-and-service template - Instead of linking to the various support trackers - (whose URLs hopefully change soon), link to the - contact section of the user manual to increase the - chances that users actually read it. -
Add a FAQ entry for tainted sockets. -
More sections in the documentation have stable URLs now. -
FAQ: Explain why 'ping config.privoxy.org' is not expected - to reach a local Privoxy installation. -
Note that donations done through Zwiebelfreunde e.V. currently - can't be checked automatically. -
Updated section regarding starting Privoxy under OS X. -
Use dedicated start instructions for FreeBSD and ElectroBSD. -
Removed release instructions for AIX. They haven't been working - for years and unsurprisingly nobody seems to care. -
Removed obsolete reference to the solaris-dist target. -
Updated the release instructions for FreeBSD. -
Removed unfinished release instructions for Amiga OS and HP-UX 11. -
Added a pointer to the Cygwin Time Machine for getting the last release of - Cygwin version 1.5 to use for building Privoxy on Windows. -
Various typos have been fixed. -
Infrastructure improvements: -
The website is no longer hosted at SourceForge and - can be reached through https now. -
The mailing lists at SourceForge have been deprecated, - you can subscribe to the new ones at: https://lists.privoxy.org/ -
Migrating the remaining services from SourceForge is - work in progress (TODO list item #53). -
Build system improvements: -
Add configure argument to optimistically redefine FD_SETSIZE - with the intent to change the maximum number of client - connections Privoxy can handle. Only works with some libcs. - Sponsored by Robert Klemme. -
Let the tarball-dist target skip files in ".git". -
Let the tarball-dist target work in cwds other than current. -
Make the 'clean' target faster when run from a git repository. -
Include tools in the generic distribution. -
Let the gen-dist target work in cwds other than current. -
Sort find output that is used for distribution tarballs - to get reproducible results. -
Don't add '-src' to the name of the tar ball generated by the - gen-dist target. The package isn't a source distribution but a - binary package. - While at it, use a variable for the name to reduce the chances - that the various references get out of sync and fix the gen-upload - target which was looking in the wrong directory. -
Add regression-tests.action to the files that are distributed. -
The gen-dist target which was broken since 2002 (r1.92) has been fixed. -
Remove genclspec.sh which has been obsolete since 2009. -
Remove obsolete reference to Redhat spec file. -
Remove the obsolete announce target which has been commented out years ago. -
Let rsync skip files if the checksums match. -
Privoxy-Regression-Test: -
Add a "Default level offset" directive which can be used to - change the default level by a given value. - This directive affects all tests located after it until the end - of the file or a another "Default level offset" directive is reached. - The purpose of this directive is to make it more convenient to skip - similar tests in a given file without having to remove or disable - the tests completely. -
Let test level 17 depend on FEATURE_64_BIT_TIME_T - instead of FEATURE_PTHREAD which has no direct connection - to the time_t size. -
Fix indentation in perldoc examples. -
Don't overlook directives in the first line of the action file. -
Bump version to 0.7. -
Fix detection of the Privoxy version now that https:// - is used for the website. -
A quick list of things to be aware of before upgrading from earlier - versions of Privoxy:
The recommended way to upgrade Privoxy is to backup your old - configuration files, install the new ones, verify that Privoxy - is working correctly and finally merge back your changes using - diff and maybe patch. -
There are a number of new features in each Privoxy 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 - Privoxy isn't always possible anyway. -
Note that some installers remove earlier versions completely, - including configuration files, therefore you should really save - any important configuration files! -
On the other hand, other installers don't overwrite existing configuration - files, thinking you will want to do that yourself. -
In the default configuration only fatal errors are logged now. - You can change that in the debug section - of the configuration file. You may also want to enable more verbose - logging until you verified that the new Privoxy version is working - as expected. -
Three other config file settings are now off by default: - enable-remote-toggle, - enable-remote-http-toggle, - and enable-edit-actions. - If you use or want these, you will need to explicitly enable them, and - be aware of the security issues involved. -
Privoxy 3.0.29 fixes a couple of memory leaks and introduces https inspection + which allows to filter encrypted requests and responses.
+Changes in Privoxy 3.0.29 stable:
+Security/Reliability:
+Fixed memory leaks when a response is buffered and the buffer limit is reached or Privoxy is running out + of memory. Commits bbd53f1010b and 4490d451f9b. OVE-20201118-0001. Sponsored by: Robert Klemme
+Fixed a memory leak in the show-status CGI handler when no action files are configured. Commit + c62254a686. OVE-20201118-0002. Sponsored by: Robert Klemme
+Fixed a memory leak in the show-status CGI handler when no filter files are configured. Commit + 1b1370f7a8a. OVE-20201118-0003. Sponsored by: Robert Klemme
+Fixes a memory leak when client tags are active. Commit 245e1cf32. OVE-20201118-0004. Sponsored by: + Robert Klemme
+Fixed a memory leak if multiple filters are executed and the last one is skipped due to a pcre error. + Commit 5cfb7bc8fe. OVE-20201118-0005.
+Prevent an unlikely dereference of a NULL-pointer that could result in a crash if + accept-intercepted-requests was enabled, Privoxy failed to get the request destination from the Host header + and a memory allocation failed. Commit 7530132349. CID 267165. OVE-20201118-0006.
+Fixed memory leaks in the client-tags CGI handler when client tags are configured and memory allocations + fail. Commit cf5640eb2a. CID 267168. OVE-20201118-0007.
+Fixed memory leaks in the show-status CGI handler when memory allocations fail. Commit 064eac5fd0 and + commit fdee85c0bf3. CID 305233. OVE-20201118-0008.
+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. 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.

+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.
