Privoxy 3.0.16 is a stable release. - The changes since 3.0.15 beta are:
Added the config file option handle-as-empty-doc-returns-ok to - work around Firefox bug #492459, which causes Firefox to hang - if JavaScripts are blocked in certain situations. The option is - enabled in the default config file. -
Added the config option default-server-timeout to control the - assumed default server timeout. Since Privoxy no longer returns - an error message for connection resets on reused client connections, - assuming larger server timeout values appears to actually work - pretty well as long as connections aren't shared. -
Added optional support for FreeBSD's accf_http(9). Use the - configure option --enable-accept-filter to enable it. -
Added fancier Privoxy icons for win32. Contributed by Jeff H. -
In daemon mode, fd 0, 1 and 2 are bound to /dev/null. -
Resolve localhost using whatever address family the operating - system feels like. Previous betas would try to use IPv4 as this - is what most users expect, but this didn't work reliable on - GNU/Linux systems. -
In the action lists on CGI pages, actions and their parameters are - no longer separated with a space. The action file parser doesn't - actually allow this and will throw an invalid syntax error if actions - and parameters in the action files are separated. Not adding the - spaces means copy and pasting CGI output into the action files works. -
The default keep-alive timeout has been reduced to 5 seconds to work - around hangs in clients that treat the proxy like any other host and - stop allowing any new connections if the "maximum number of - connections per host" is reached. -
Several webbug URLs that look like they are leading to images are now - blocked as image instead of empty documents. Doing the latter causes - WebKit-based clients to show a "missing image" icon which may mess up - the layout. -
Accepts quoted expiration dates even though RFC 2109 10.1.2 - doesn't seem to allow them. Reported anonymously. -
Don't try to forget connections if connection sharing is disabled. - This wasn't a real problem but caused an unnecessary log message. -
The still undocumented --enable-extended-host-patterns configure - option has a better description. -
Fixed an error message that would claim a write to the server - failed when actually writing to the client failed. -
Log the crunch reason before trying to write to the client. - The log is easier to read that way. -
Several log messages about client connections also mention - the socket number. -
handle-as-empty-document no longer depends on the image blocking - code being enabled. -
Privoxy-Log-Parser is roughly 40% faster in highlighting mode. -
uagen, a Firefox User-Agent generator for Privoxy and Mozilla - browsers has been imported and is available in the tarballs - tools directory. -
The scripts in the tools directory treat unknown parameters - as fatal errors. -
If you missed the previous two beta versions, you may also be - interested in the additional changes since 3.0.12, the - last stable release:
Added IPv6 support. Thanks to Petr Pisar who not only provided - the initial patch but also helped a lot with the integration. -
Added client-side keep-alive support. -
The connection sharing code is only used if the connection-sharing - option is enabled. -
The latency is taken into account when evaluating whether or not to - reuse a connection. This should significantly reduce the number of - connections problems several users reported. -
The max-client-connections option has been added to restrict - the number of client connections below a value enforced by - the operating system. -
If the server doesn't specify how long the connection stays alive, - Privoxy errs on the safe side of caution and assumes it's only a second. -
Setting keep-alive-timeout to 0 disables keep-alive support. Previously - Privoxy would claim to allow persistence but not reuse the connection. -
Pipelined requests are less likely to be mistaken for the request - body of the previous request. Note that Privoxy still has no real - pipeline support and will either serialize pipelined requests or - drop them in which case the client has to resent them. -
Fixed a crash on some Windows versions when header randomization - is enabled and the date couldn't be parsed. -
Privoxy's keep-alive timeout for the current connection is reduced - to the one specified in the client's Keep-Alive header. -
For HTTP/1.1 requests, Privoxy implies keep-alive support by not - setting any Connection header instead of using 'Connection: keep-alive'. -
If the socket isn't reusable, Privoxy doesn't temporarily waste - a socket slot to remember the connection. -
If keep-alive support is disabled but compiled in, the client's - Keep-Alive header is removed. -
Fixed a bug on mingw32 where downloading large files failed if - keep-alive support was enabled. -
Fixed a bug that (at least theoretically) could cause log - timestamps to be occasionally off by about a second. -
The configure script respects the $PATH variable when searching - for groups and id. -
Compressed content with extra fields couldn't be decompressed - and would get passed to the client unfiltered. This problem - has only be detected through statical analysis with clang as - nobody seems to be using extra fields anyway. -
If the server resets the Connection after sending only the headers - Privoxy forwards what it got to the client. Previously Privoxy - would deliver an error message instead. -
Error messages in case of connection timeouts use the right - HTTP status code. -
If spawning a child to handle a request fails, the client - gets an error message and Privoxy continues to listen for - new requests right away. -
The error messages in case of server-connection timeouts or - prematurely closed server connections are now template-based. -
If zlib support isn't compiled in, Privoxy no longer tries to - filter compressed content unless explicitly asked to do so. -
In case of connections that are denied based on ACL directives, - the memory used for the client IP is no longer leaked. -
Fixed another small memory leak if the client request times out - while waiting for client headers other than the request line. -
The client socket is kept open until the server socket has - been marked as unused. This should increase the chances that - the still-open connection will be reused for the client's next - request to the same destination. Note that this only matters - if connection-sharing is enabled. -
A TODO list has been added to the source tarballs to give potential - volunteers a better idea of what the current goals are. Donations - are still welcome too: http://www.privoxy.org/faq/general.html#DONATE -
In case of missing server data, no error message is send to the - client if the request arrived on a reused connection. The client - is then supposed to silently retry the request without bothering - the user. This should significantly reduce the frequency of the - "No server or forwarder data received" error message many users - reported. -
More reliable detection of prematurely closed client sockets - with keep-alive enabled. -
FEATURE_CONNECTION_KEEP_ALIVE is decoupled from - FEATURE_CONNECTION_SHARING and now available on - all platforms. -
Improved handling of POST requests on reused connections. - Should fix problems with stalled connections after submitting - form data with some browser configurations. -
Fixed various latency calculation issues. -
Allows the client to pass NTLM authentication requests to a - forwarding proxy. This was already assumed and hinted to work - in 3.0.13 beta but actually didn't. Now it's confirmed to work - with IE, Firefox and Chrome. - Thanks to Francois Botha and Wan-Teh Chang -
Fixed a calculation problem if receiving the server headers - takes more than two reads, that could cause Privoxy to terminate - the connection prematurely. Reported by Oliver. -
Compiles again on platforms such as OpenBSD and systems - using earlier glibc version that don't support AI_ADDRCONFIG. - Anonymously submitted in #2872591. -
A bunch of MS VC project files and Suse and Redhat RPM spec - files have been removed as they were no longer maintained for - quite some time. -
Overly long action lines are properly rejected with a proper - error message. Previously they would be either rejected as - invalid or cause a core dump through abort(). -
Already timed-out connections are no longer temporarily remembered. - They weren't reused anyway, but wasted a socket slot. -
len refers to the number of bytes actually read which might - differ from the ones received. Adjust log messages accordingly. -
The optional JavaScript on the CGI page uses encodeURIComponent() - instead of escape() which doesn't encode all characters that matter. - Anonymously reported in #2832722. -
Fix gcc45 warnings in decompress_iob(). -
Various log message improvements. -
Privoxy-Regression-Test supports redirect tests. -
Privoxy-Log-Parser can gather some connection statistics. -
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. -
- standard.action has been merged into - the default.action file. -
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 3.0.31 fixes two security issues that were discovered while preparing + the 3.0.30 release. The issues also affect earlier Privoxy releases.
+Changes in Privoxy 3.0.31 stable:
+Security/Reliability:
+Prevent an assertion from getting triggered by a crafted CGI request. Commit 5bba5b89193fa. + OVE-20210130-0001. Reported by: Joshua Rogers (Opera)
+Fixed a memory leak when decompression fails "unexpectedly". Commit f431d61740cc0. + OVE-20210128-0001.
+Bug fixes:
+Fixed detection of insufficient data for decompression. Previously Privoxy could try to decompress a + partly uninitialized buffer.
+Changes in Privoxy 3.0.30 stable:
+Bug fixes:
+Check the actual URL for redirects when https inspecting requests. Previously Privoxy would only check + the path which resulted in rewrite results being rejected as invalid URLs. Reported by withoutname in + #1736.
+Let the hide-referrer code tolerate Referer headers with https:// URLs. Previously they would always be + treated like a changed host.
+Use the https headers if the show-request handler is reached through https://. Previously Privoxy would + use the http headers which may be empty on a reused connection.
+Make CGI_PREFIX protocol-relative when building with FEATURE_HTTPS_INSPECTION. This unbreaks (at least) + https://config.privoxy.org/client-tags whose buttons would previously use a http:// URL resulting in + browser warnings.
+Support using https-inspection and client-header-order at the same time. Previously Privoxy would crash. + Reported by: Kai Raven
+Properly reject rewrites from http to https as they currently aren't supported. Previously Privoxy would + wait for the client to establish an encrypted connection which obviously would not happen.
+When https inspection is enabled and Privoxy has been compiled with FEATURE_GRACEFUL_TERMINATION (not + recommended for production builds), the TLS backend resources are free'd later on and only if no active + connections are left. Prevents crashes when exiting "gracefully" at the wrong time.
+Let the uninstall target remove the config file even if DESTDIR is set and properly announce the + deletion of the configuration files.
+General improvements:
+Allow to rewrite the request destination for https-inspected requests behind the client's back. The + documentation already sort of claimed that it was supported by not especially mentioning that it didn't + work for https-inspected requests. Fixes SF bug #923 reported by withoutname.
+Add support for filtering client request bodies by using CLIENT-BODY-FILTER filters which can be enabled + with the client-body-filter action. Patch submitted by Maxim Antonov. Sponsored by: Robert Klemme
+Add the new action suppress-tag{} which can be used to prevent a tagger from adding a tag. Patch + submitted by Maxim Antonov. Sponsored by: Robert Klemme
+Gracefully handle existing website keys without matching certificates. This can happen if Privoxy was + previously running with an invalid TLS configuration that didn't allow it to create a certificate.
+Recycle debug bit 4 for Tagging-related messages.
+Improve the message shown when the client-tags CGI page is requested with no tags configured.
+Shorten the 'donate' and 'participate' links used by templates using redirects. Currently the redirects + lead to the FAQ entries but in the future we may want to relocate the content and using redirects makes + this more convenient.
+Log an error when a PCRE-HOST-PATTERN is used with FEATURE_PCRE_HOST_PATTERNS disabled. Don't treat this + a fatal error so the regression tests can be used with and without FEATURE_PCRE_HOST_PATTERNS.
+The code compiles with older C compilers again.
+The chdir() return code is checked to fix a compiler warning.
+The packages feed has been removed from the source tarball. It's usually out of date when the source + tarball is generated for the release.
+Fixed harmless compiler warnings from GCC9 with -D_FORTIFY_SOURCE=2.
+windows: Remove obsolete '$(DEST)/doc/images' target.
+windows: Install the images referenced in the user manual.
+Remove obsolete 'gnu_regex.@OBJEXT@' target.
+When installing from the GNUMAkefile, don't create an 'images' directory which is no longer used. The + images were relocated to the user-manual directory years ago.
+Add new FEATURES to the show-status page and resort list.
+Remove unused variable in the OpenSSL-specific code.
+Update bug tracker URL in cgi_error_unknown().
+Saved a couple of memory allocations when sorting client headers.
+Improved a couple of error messages.
+Saved memory allocations when using OpenSSL and checking if a key already exists.
+The configure script will bail out if OpenSSL and mbedTLS are enabled at the same time.
+Log a message right before exiting gracefully.
+A couple of structures have been rearranged to require slightly less memory.
+When https inspection is enabled and the certificate is invalid the error message is now sent with + status code 403 instead of 200.
+The Slackware rc script template has been renamed to slackware/rc.privoxy.in to silence complaints when + building Debian packages.
+When building with MbedTLS support, mbedtls_md5_ret() is used instead of mbedtls_md5() which is + deprecated and causes a warning on Debian GNU/Linux.
+Action file improvements:
+Block requests to eu-tlp03.kameleoon.com/.
+Unblock metrics.sr.ht/.
+Disable fast-redirects for .fsf.org/.
+Disable fast-redirects for .gravater.com/.
+Disable fast-redirects for .ksta.de/.
+Block requests to tag.crsspxl.com/.
+Block requests to analytics.slashdotmedia.com/.
+Block requests to ml314.com/.
+Block requests to .adroll.com/.
+Block requests to fastlane.rubiconproject.com/.
+Block requests to api.theadex.com/.
+Block requests to ih.adscale.de/.
+Block requests to .s400.meetrics.net/.
+Block requests for pp.lp4.io/.
+Block requests for trc-events.taboola.com/.
+Filter file improvements:
+A allow-autocompletion filter has been added which changes autocomplete="off" to "on" on input fields to + allow autocompletion. Requested by Jamie Zawinski in #370. Filter based on a submission by Aaron + Linville.
+Added an imdb filter.
+Added a sourceforge filter that reduces the amount of ads for proprietary software.
+Added a github filter that removes the annoying "Sign-Up" banner and the Cookie disclaimer.
+Removed a duplicated pcrs command from the js-annoyances filter.
+The crude-parental filter now provides a short reason when blocking, inserts a link to Privoxy's + webinterface and adds a new line at the end of the generated page.
+Privoxy-Log-Parser:
+Highlight a few more messages.
+Add a handler for tagging messages.
+Properly deal with 'Certificate error' crunches Previously the error description was highlighted as + 'host'.
+Log truncated LOG_LEVEL_CLF messages more gracefully and note that the statistics will be imprecise.
+Fixed perldoc typo.
+Bump version to 0.9.2.
+Privoxy-Regression-Test:
+Use http://127.0.0.1:8118/ as default Privoxy address unless http_proxy is set through the + environment.
+Add a --privoxy-cgi-prefix option that specifies the prefix to use when building URLs that are supposed + to reach Privoxy's CGI interface. If it's not set, http://p.p/ is used, which is supposed to work with the + default Privoxy configuration. If Privoxy has been built with FEATURE_HTTPS_INSPECTION enabled, and if + https inspection is activated with the +https-inspection action, this option can be used with + "https://p.p/" provided the system running Privoxy-Regression-Test has been configured to trust the + certificate used by Privoxy. Note that there are currently two tests in the official + regression-tests.action file that are expected to fail when using "https://p.p/" as privoxy-cgi-prefix.
+Skip the connection-established response in get_status_code() when looking for the status code with a + CGI prefix that starts with https://. We care about the status code sent by the impersonated web + server.
+Use --proxy-header when using a CGI prefix with https:// and a "Host:" header.
+Allow '|' in tokens and values to allow tag patterns like + "TAG:^(application|text)/(x-)?javascript$".
+When get_cgi_page_or_else() fails, include the URL of the requested page in the log message.
+Added a --check-bad-ssl option that can be used to verify that Privoxy detects certificate problems when + accessing the test sites from badssl.com.
+Bumped version to 0.7.2
+uagen:
+Update example output.
+Recommend the use of the https-inspection action in the documentation.
+Upgrade a couple of URLs to https://.
+Add ElectroBSD to the list of operating systems.
+Bumped generated Firefox version to 78 (ESR).
+Bumped version to 1.2.2.
+User documentation:
+Remove reference to 'How to Report Bugs Effectively'. It was only rendered as text without URL in the + README anyway and there's no indication that users read it ...
+Let the dok-readme target fix the location embedded into the README file. This used to be done by CVS + but since the git migration it has to be done through other means.
+Remove 'experimental' warning for client-specific-tag-related directives. They seem to work reliably and + there is no obvious reason why we would change the syntax in the near future.
+Describe how to check if Privoxy has been built with FEATURE_HTTPS_INSPECTION.
+Add a link to the trusted-cas-file documentation that explains how the user can create the file + herself.
+Don't explicitly mention the license for the code coming from 'Anonymous Coders' and Junkbusters. It's + obviously licensed under the GNU GPL like the rest of Privoxy or we wouldn't be allowed to distribute + it.
+Update the +hide-user-agent example with uagen output.
+Slightly improve the wording of the ca-key-file documentation.
+Explicitly mention Windows 10 as supported so search engines and users looking for it can find it.
+Import a bunch of contributors from the ChangeLog.
+Remove obsolete doc/gpl.html.
+Upgrade a couple of links to https://.
+Don't prefer the SourceForge patch tracker over the privoxy-devel mailing list. While at it, link to the + SourceForge patch tracker.
+Mention http-inspection in the 'my browser warns me about unauthenticated content' FAQ entry.
+Simplify the 'Is there is a license or fee?' FAQ entry.
+Add another +redirect{} example.
+Explicitly mention that interested sponsors should include the link target in their first mail.
+Clarify that only Privoxy team members can object to new sponsors and link to the list of current team + members.
+Note that sponsor URLs may not contain keyword spam.
+Garbage collect doc/webserver/images which isn't referenced anymore.
+Update the method to reach the proxy settings in Firefox.
+Update proxy_setup.jpg description to refer to Firefox.
+Regenerate proxy_setup.jpg with a more recent Firefox (78.0).
+Regenerate files-in-use.jpg without obsolete standard.action with modern colors and a slightly better + quality.
+Update URL to the actionsfile tracker.
+Update a support request URL.
+Rephrase the 'Can Privoxy run as service' FAQ entry and remove an obsolete paragraph.
+Let the 'Where can I get updated Actions Files?' entry link to the gitweb version of + default.action.master.
+Update a link to the default.action file.
+Update URLs for trackers and mailing lists.
+Replace CVS reference with git.
+Mention regression-tests.action in the config file.
+Explicitly mention in the config file that access to the CA key should be limited to Privoxy.
+List more client-specific-tag examples for inspiration.
+Add additional headers to the client-header-order example.
+Note that actions aren't updated after rewrites.
+Explicitly mention that upgrading from http to https with a client-header filter is not supported
+Note that protocol and host have to be added when rewriting the destination host for https-inspected + requests.
+Explicitly mention that the CA key is used to sign certificates.
+Put openssl command in 'command' tags.
+The man page has been moved from section 1 to man section 8.
+Developer manual:
+Flesh out the build instructions for Debian.
+Remove the packaging instructions for RPM-based systems. They don't work and we don't release RPM + packages anymore anyway.
+Remove the packaging instructions for Solaris. They don't work and we don't release Solaris packages + anymore anyway.
+Update the suggested subject for the announce mails.
+Update upload instructions. ftp://upload.sourceforge.net is no longer functional.
+Remove a couple of package-dependent upload instructions that don't actually work.
+Remove 'cd current' that no longer works.
+Add regression-tests.action to the list of files that should be installed.
+Stop claiming that there are text versions of the manuals. We stopped building them in 2008 + (9ed36a3c5e6f12).
+Note that the 'webserver' target creates the link needed for the user-manual.
+Suggest to use the master branch as reference when creating the ChangeLog so the steps work when the + current branch differs from master which is likely as the developer manual suggests to use a local branch + for development.
+Add the -s flag to the suggested 'git tag' command. We prefer signed tags.
+Mention that merges into 'master' should be avoided.
+Add git commands that should result in a merge-free history.
+Mention Privoxy-Regression-Test.
+Add a section id to reduce link churn.
+Recommend the dok-tidy target when building docs for the webserver.
+Add another plug for the privoxy-devel mailing list.
+Let the intro link the copyright section in the user manual instead of giving an incomplete summary of + the license status.
+Clarify that the webserver target uploads to the SourceForge webserver.
+Mark the documentation for the Mac OS X installers as out of date and change the SCM name back to + CVS.
+Fix the location of the installer modules for Mac OS X. They are not actually available through git + (yet).
+Don't speak of Privoxy version 3 in the past tense.
+Update the list of programs required for the release process.
+Update description of the webserver target which uses ssh, not scp.
+Remove obsolete reference to config.new.
+Tests:
+Add another hide-referrer{conditional-block} test.
+Add another hide-referrer{conditional-forge} test.
+Fix a hide-referrer{conditional-forge} test that expected an acceptable header to be forged.
+Fix a hide-referrer{conditional-block} test that expected an acceptable Referer to be removed.
+Explain why the "Set Header = Host: whatever.example.org" test is expected to fail when using a CGI + prefix that starts with "https://".
+Explain why a connection-sharing test is known to fail when using "https://p.p/" as CGI prefix.
+Add a link to Privoxy-Regression-Test to regression-tests.action in case it isn't packaged.
+Add regression tests for pcre host patterns.
+Fixed a regression test that is executed when FEATURE_GRACEFUL_TERMINATION is enabled.
+Privoxy infrastructure:
+Import a Privoxy logo for the website.
+Update Tor onion service to HiddenServiceVersion 3.
+Display the "model" photos in a single row and remove placeholder images.
+Regenerate homepage with updated sponsor list.
+Use the '/sponsor' redirect for the link to the sponsor page.
+Git commit messages are sent to the Privoxy-commits mailing list.
