There are many improvements and new features in Privoxy 3.0.4 - :
Mulitiple filter files can now be specifed in config. This allows for - locally defined filters that can be maintained separately from the filters as - supplied by the developers. -
- There are a number of new actions: -
redirect -
In addition, fast-redirects - has been significantly improved with enhanced syntax. -
And hide-referrer - has a new option, conditional block. -
MS-Windows versions can now be - installed and - started as a Windows service. -
config has two new options: - enable-remote-http-toggle, - and forwarded-connect-retries. -
And there is improved handling of the user-manual - option, for placing documentation and help files on the local system. -
Actions files problems and suggestions are now being directed to: http://sourceforge.net/tracker/?group_id=11118&atid=460288. - Please use this to report such configuration related problems as missed - ads, sites that don't function properly due to one action or another, - innocent images being blocked, etc. -
In addition, there are various bug fixes and significant enhancements, including - error pages should no longer be cached if the problem is fixed, better DNS - error handling, and various logging improvements. -
A quick list of things to be aware of before upgrading from earlier - versions of Privoxy:
- Some installers may remove earlier versions completely, including - configuration files. Save any important configuration files! -
- On the other hand, some installers may not overwrite any existing configuration - files, thinking you will want to do that. You may want to manually check - your saved files against the newer versions to see if the improvements have - merit, or whether there are new options that you may want to consider. - There are a number of new features, but most won't be available unless - these features are incorporated into your configuration somehow. -
See the full documentation on - fast-redirects - which has changed syntax, and may require adjustments to local configs. -
The jarfile, cookie logger, is off by default now. -
- What constitutes a "default" configuration has changed, - and you may want to review which actions are "on" by - default. This is primarily a matter of emphasis, but some features - you may have been used to, may now be "off" by default. -
- Some installers may not automatically start - Privoxy after installation. -
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 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.

+Updated the location of the development version of default.action.master.
+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.

+Add the new 'PCRE-HOST-PATTERN:' prefix. Sponsored by: Robert Klemme
+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.
