ChangeLog for Privoxy
--------------------------------------------------------------------
+*** Version 3.0.33 stable ***
+- Security/Reliability:
+ - cgi_error_no_template(): Encode the template name to prevent
+ XSS (cross-site scripting) when Privoxy is configured to servce
+ the user-manual itself.
+ Commit 0e668e9409c. OVE-20211102-0001. CVE-2021-44543.
+ Reported by: Artem Ivanov
+ - get_url_spec_param(): Free memory of compiled pattern spec
+ before bailing.
+ Reported by Joshua Rogers (Opera) who also provided the fix.
+ Commit 652b4b7cb0. OVE-20211201-0003. CVE-2021-44540.
+ - process_encrypted_request_headers(): Free header memory when
+ failing to get the request destination.
+ Reported by Joshua Rogers (Opera) who also provided the fix.
+ Commit 0509c58045. OVE-20211201-0002. CVE-2021-44541.
+ - send_http_request(): Prevent memory leaks when handling errors
+ Reported by Joshua Rogers (Opera) who also provided the fix.
+ Commit c48d1d6d08. OVE-20211201-0001. CVE-2021-44542.
+
+- Bug fixes:
+ - handle_established_connection(): Skip the poll()/select() calls
+ if TLS data is pending on the server socket. The TLS library may
+ have already consumed all the data from the server response in
+ which case poll() and select() will not detect that data is
+ available to be read.
+ Fixes SF bug #926 reported by Wen Yue.
+ - continue_https_chat(): Update csp->server_connection.request_sent
+ after sending the request to make sure the latency is calculated
+ correctly. Previously https connections were not reused after
+ timeout seconds after the first request made on the connection.
+ - free_pattern_spec(): Don't try to free an invalid pointer
+ when unloading an action file with a TAG pattern while
+ Privoxy has been compiled without FEATURE_PCRE_HOST_PATTERNS.
+ Closes: SF patch request #147. Patch by Maxim Antonov.
+ - Adjust build_request_line() to create a CONNECT request line when
+ https-inspecting and forwarding to a HTTP proxy.
+ Fixes SF bug #925 reported by Wen Yue.
+ - load_config(): Add a space that was missing in a log message.
+ - read_http_request_body(): Fix two error messages that used an
+ incorrect variable.
+ - If the the response is chunk-encoded, ignore the Content-Length
+ header sent by the server.
+ Allows to load https://redmine.lighttpd.net/ with filtering enabled.
+
+- General improvements:
+ - 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.
+ Reported by: Wen Yue
+ - OpenSSL generate_host_certificate(): Fix two error messsages.
+ - Improve description of handle_established_connection()
+ - OpenSSL ssl_store_cert(): Translate EVP_PKEY_EC to a string.
+ - OpenSSL ssl_store_cert(): Remove pointless variable initialization.
+ - OpenSSL ssl_store_cert(): Initialize pointer with NULL instead of 0.
+
+- Action file improvements:
+ - Disable fast-redirects for .microsoftonline.com/.
+ - Disable fast-redirects for idp.springer.com/.
+ - Disable fast-redirects for .zeit.de/zustimmung.
+ - Unblock adv-archiv.dfn-cert.de/.
+ - Block requests to eu-tlp01.kameleoon.eu/.
+ - Block requests to fpa-events.arstechnica.com/.
+ - Unblock nlnet.nl/.
+ - Unblock adguard.com/.
+
+- Privoxy-Log-Parser:
+ - Highlight 'Socket timeout 3 reached: http://127.0.0.1:20000/no-filter/chunked-content/36'.
+ - Improve documentation for inactivity-detection mode.
+ - Detect date changes when looking for inactivity.
+ - Add a --passed-request-statistics-threshold option
+ that can be set to get statistics for requests that
+ were passed.
+ - Add a "inactivity detection" mode which can be useful
+ for debugging purposes.
+ - Bump version to 0.9.4.
+ - Only run print_intro() and print_outro() when syntax highlighting.
+ - Rephrase a sentence in the documentation.
+ - Highlight 'Client socket 7 is no longer usable. The server socket has been closed.'.
+ - Clarify --statistics output by explicitly mentioning that
+ the status codes sent by the server may differ from the ones
+ in "debug 512" messages.
+ - Fix typo in the --statistics output.
+ - Remove an unused variable.
+ - Highlight 'The peer notified us that the connection on socket 11 is going to be closed'.
+
+- Privoxy-Regression-Test:
+ - Remove duplicated word in a comment.
+
+- regression-tests.action:
+ - Add fetch test for http://p.p/wpad.dat.
+ - Bump for-privoxy-version to 3.0.33 which introduced the wpad.dat support.
+ - Add more tests for the '/send-banner' code.
+ - Add test for OVE-20210203-0001.
+ - Add a test for CVE-2021-20217.
+
+- uagen:
+ - Bump generated Firefox version to 91 (ESR).
+ - Bump version to 1.2.3.
+ - Bump copyright.
+
+- Build system:
+ - configure: Bump SOURCE_DATE_EPOCH.
+ - GNUmakefile.in: Fix typo.
+ - configure: Add another warning in case --disable-pthread
+ is used while POSIX threads are available.
+ Various features don't even compile when not using threads.
+ - Add configure option to enable MemorySanitizer.
+ - Add configure option to enable UndefinedBehaviorSanitizer.
+ - Add configure option to enable AddressSanitizer.
+ - Bump copyright.
+ - Add a configure option to disable pcre JIT compilation.
+ While JIT compilation makes filtering faster it can
+ cause false-positive valgrind complaints.
+ As reported by Gwyn Ciesla in SF bug 924 it also can
+ cause problems when the SELinux policy does not grant
+ Privoxy "execmem" privileges.
+ - configure: Remove obsolete RPM_BASE check.
+
+- Windows build system:
+ - Update the build script to use mbed tls version 2.6.11.
+ - Update build script to use the final 8.45 pcre library.
+ - Put all the '--enable-xxx' options in the configure call together.
+
+- macOS build system:
+ - The OSXPackageBuilder repository has been updated and
+ can be used to create macOS packages again.
+
+- Documentation:
+ - contacting: Remove obsolete reference to announce.sgml.
+ - contacting: Request that the browser cache is cleared before
+ producing a log file for submission.
+ - Sponsor FAQ: Note that Privoxy users may follow sponsor links
+ without Referer header set.
+ - newfeatures: Clarify that https inspection also allows to
+ filter https responses.
+ - developer-manual: Mention that announce.txt should be updated
+ when doing a release.
+ - config: Explicitly mention that the CGI pages disclosing the
+ ca-password can be blocked and upgrade the disclosure paragraphs
+ to a warning.
+ - Put all the requested debug options in the config file.
+ Section 11.1 of the Privoxy user manual lists all the debug
+ options that should be enabled when reporting problems or requesting support.
+ Make it easier for users to do the right thing by having all those
+ options present in the config.
+ - Update TODO list item #184 to note that WolfSSL support will
+ (hopefully) appear after the 3.0.34 release.
+ - Update max-client-connections's description.
+ On modern systems other than Windows Privoxy should
+ use poll() in which case the FD_SETSIZE value isn't
+ releveant.
+ - Add a warning that the socket-timeout does not apply
+ to operations done by TLS libraries.
+ - Make documentation slightly less "offensive" for some people
+ by avoiding the word "hell".
+
+*** Version 3.0.32 stable ***
+
+- Security/Reliability:
+ - ssplit(): Remove an assertion that could be triggered with a
+ crafted CGI request.
+ Commit 2256d7b4d67. OVE-20210203-0001. CVE-2021-20272.
+ Reported by: Joshua Rogers (Opera)
+ - cgi_send_banner(): Overrule invalid image types. Prevents a
+ crash with a crafted CGI request if Privoxy is toggled off.
+ Commit e711c505c48. OVE-20210206-0001. CVE-2021-20273.
+ Reported by: Joshua Rogers (Opera)
+ - socks5_connect(): Don't try to send credentials when none are
+ configured. Fixes a crash due to a NULL-pointer dereference
+ when the socks server misbehaves.
+ Commit 85817cc55b9. OVE-20210207-0001. CVE-2021-20274.
+ Reported by: Joshua Rogers (Opera)
+ - chunked_body_is_complete(): Prevent an invalid read of size two.
+ Commit a912ba7bc9c. OVE-20210205-0001. CVE-2021-20275.
+ Reported by: Joshua Rogers (Opera)
+ - Obsolete pcre: Prevent invalid memory accesses with an invalid
+ pattern passed to pcre_compile(). Note that the obsolete pcre code
+ is scheduled to be removed before the 3.0.33 release. There has been
+ a warning since 2008 already.
+ Commit 28512e5b624. OVE-20210222-0001. CVE-2021-20276.
+ Reported by: Joshua Rogers (Opera)
+
+- Bug fixes:
+ - Properly parse the client-tag-lifetime directive. Previously it was
+ not accepted as an obsolete hash value was being used.
+ Reported by: Joshua Rogers (Opera)
+ - decompress_iob(): Prevent reading of uninitialized data.
+ Reported by: Joshua Rogers (Opera).
+ - decompress_iob(): Don't advance cur past eod when looking
+ for the end of the file name and comment.
+ - decompress_iob(): Cast value to unsigned char before shifting.
+ Prevents a left-shift of a negative value which is undefined behaviour.
+ Reported by: Joshua Rogers (Opera)
+ - gif_deanimate(): Confirm that that we have enough data before doing
+ any work. Fixes a crash when fuzzing with an empty document.
+ Reported by: Joshua Rogers (Opera).
+ - buf_copy(): Fail if there's no data to write or nothing to do.
+ Prevents undefined behaviour "applying zero offset to null pointer".
+ Reported by: Joshua Rogers (Opera)
+ - log_error(): Treat LOG_LEVEL_FATAL as fatal even when --stfu is
+ being used while fuzzing.
+ Reported by: Joshua Rogers (Opera).
+ - Respect DESTDIR when considering whether or not to install
+ config files with ".new" extension.
+ - OpenSSL ssl_store_cert(): Fix two error messages.
+ - Fix a couple of format specifiers.
+ - Silence compiler warnings when compiling with NDEBUG.
+ - fuzz_server_header(): Fix compiler warning.
+ - fuzz_client_header(): Fix compiler warning.
+ - cgi_send_user_manual(): Also reject requests if the user-manual
+ directive specifies a https:// URL. Previously Privoxy would try and
+ fail to open a local file.
+
+- General improvements:
+ - Log the TLS version and the the cipher when debug 2 is enabled.
+ - ssl_send_certificate_error(): Respect HEAD requests by not sending a body.
+ - ssl_send_certificate_error(): End the body with a single new line.
+ - serve(): Increase the chances that the host is logged when closing
+ a server socket.
+ - handle_established_connection(): Add parentheses to clarify an expression
+ Suggested by: David Binderman
+ - continue_https_chat(): Explicitly unset CSP_FLAG_CLIENT_CONNECTION_KEEP_ALIVE
+ if process_encrypted_request() fails. This makes it more obvious that the
+ connection will not be reused. Previously serve() relied on
+ CSP_FLAG_SERVER_CONTENT_LENGTH_SET and CSP_FLAG_CHUNKED being unset.
+ Inspired by a patch from Joshua Rogers (Opera).
+ - decompress_iob(): Add periods to a couple of log messages
+ - Terminate the body of the HTTP snipplets with a single new line
+ instead of "\r\n".
+ - configure: Add --with-assertions option and only enable assertions
+ when it is used
+ - windows build: Use --with-brotli and --with-mbedtls by default and
+ enable dynamic error checking.
+ - gif_deanimate(): Confirm we've got an image before trying to write it
+ Saves a pointless buf_copy() call.
+ - OpenSSL ssl_store_cert(): Remove a superfluous space before the serial number.
+
+- Action file improvements:
+ - Disable fast-redirects for .golem.de/
+ - Unblock requests to adri*.
+ - Block requests for trc*.taboola.com/
+ - Disable fast-redirects for .linkedin.com/
+
+- Filter file improvements:
+ - Make the second pcrs job of the img-reorder filter greedy again.
+ The ungreedy version broke the img tags on:
+ https://bulk.fefe.de/scalability/.
+
+- Privoxy-Log-Parser:
+ - Highlight a few more messages.
+ - Clarify the --statistics output. The shown "Reused connections"
+ are server connections so name them appropriately.
+ - Bump version to 0.9.3.
+
+- Privoxy-Regression-Test:
+ - Add the --check-bad-ssl option to the --help output.
+ - Bump version to 0.7.3.
+
+- Documentation:
+ - Add pushing the created tag to the release steps in the developer manual.
+ - Clarify that 'debug 32768' should be used in addition to the other debug
+ directives when reporting problems.
+ - Add a 'Third-party licenses and copyrights' section to the user manual.
+
+*** Version 3.0.31 stable ***
+
+- Security/Reliability:
+ - Prevent an assertion from getting triggered by a crafted CGI request.
+ Commit 5bba5b89193fa. OVE-20210130-0001. CVE-2021-20217.
+ Reported by: Joshua Rogers (Opera)
+ - Fixed a memory leak when decompression fails "unexpectedly".
+ Commit f431d61740cc0. OVE-20210128-0001. CVE-2021-20216.
+
+- Bug fixes:
+ - Fixed detection of insufficient data for decompression.
+ Previously Privoxy could try to decompress a partly
+ uninitialized buffer.
+
+*** Version 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.

+
+- 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.
+
+- Action file improvements:
+ - Block requests to /(.*/)?piwik\.php
+ - Block requests to .connectaserver.de/
+ - Block requests to pixel.inforsea.com/
+ - Block requests to t.vi-serve.com/

+ - Unblock .adbshell.com
+ Reported by lvm in #942.
+ - Unblock .tagesschau.de/
+ - Disable fast-redirects for collector.githubapp.com/

+ - Unblock adaway.org/
+ Reported by DRS David Soft in AF#945.
+ - Change two block reasons that previously were the same.
+ Sponsored by: Robert Klemme
+ - Added a +delay-response{} test.
+ - 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.
+ - 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
+ - Skip CLIENT-TAG patterns.
+ Sponsored by: Robert Klemme
+ - Skip patterns that have already been converted.
+ It should now be safe to "convert" a file multiple times.
+ Sponsored by: Robert Klemme
+ - Add the new 'PCRE-HOST-PATTERN:' prefix.
