Anyone experiencing build problems or crashes with 0.4.1.6, + including all relays relying on AccountingMax, should upgrade. + + o Major features (directory authorities, backport from 0.4.2.2-alpha): + - Directory authorities now reject relays running all currently + deprecated release series. The currently supported release series + are: 0.2.9, 0.3.5, 0.4.0, 0.4.1, and 0.4.2. Closes ticket 31549. + + o Major bugfixes (embedded Tor, backport from 0.4.2.2-alpha): + - Avoid a possible crash when restarting Tor in embedded mode and + enabling a different set of publish/subscribe messages. Fixes bug + 31898; bugfix on 0.4.1.1-alpha. + + o Major bugfixes (relay, backport from 0.4.2.3-alpha): + - Relays now respect their AccountingMax bandwidth again. When + relays entered "soft" hibernation (which typically starts when + we've hit 90% of our AccountingMax), we had stopped checking + whether we should enter hard hibernation. Soft hibernation refuses + new connections and new circuits, but the existing circuits can + continue, meaning that relays could have exceeded their configured + AccountingMax. Fixes bug 32108; bugfix on 0.4.0.1-alpha. + + o Major bugfixes (torrc parsing, backport from 0.4.2.2-alpha): + - Stop ignoring torrc options after an %include directive, when the + included directory ends with a file that does not contain any + config options (but does contain comments or whitespace). Fixes + bug 31408; bugfix on 0.3.1.1-alpha. + + o Major bugfixes (v3 onion services, backport from 0.4.2.3-alpha): + - Onion services now always use the exact number of intro points + configured with the HiddenServiceNumIntroductionPoints option (or + fewer if nodes are excluded). Before, a service could sometimes + pick more intro points than configured. Fixes bug 31548; bugfix + on 0.3.2.1-alpha. + + o Minor features (continuous integration, backport from 0.4.2.2-alpha): + - When building on Appveyor and Travis, pass the "-k" flag to make, + so that we are informed of all compilation failures, not just the + first one or two. Closes ticket 31372. + + o Minor features (geoip, backport from 0.4.2.4-rc): + - Update geoip and geoip6 to the November 6 2019 Maxmind GeoLite2 + Country database. Closes ticket 32440. + + o Minor bugfixes (Appveyor CI, backport from 0.4.2.2-alpha): + - Avoid spurious errors when Appveyor CI fails before the install step. + Fixes bug 31884; bugfix on 0.3.4.2-alpha. + + o Minor bugfixes (client, onion service v3, backport from 0.4.2.4-rc): + - Fix a BUG() assertion that occurs within a very small race window + between when a client intro circuit opens and when its descriptor + gets cleaned up from the cache. The circuit is now closed early, + which will trigger a re-fetch of the descriptor and continue the + connection. Fixes bug 28970; bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (connections, backport from 0.4.2.3-rc): + - Avoid trying to read data from closed connections, which can cause + needless loops in Libevent and infinite loops in Shadow. Fixes bug + 30344; bugfix on 0.1.1.1-alpha. + + o Minor bugfixes (error handling, backport from 0.4.2.1-alpha): + - On abort, try harder to flush the output buffers of log messages. + On some platforms (macOS), log messages could be discarded when + the process terminates. Fixes bug 31571; bugfix on 0.3.5.1-alpha. + - Report the tor version whenever an assertion fails. Previously, we + only reported the Tor version on some crashes, and some non-fatal + assertions. Fixes bug 31571; bugfix on 0.3.5.1-alpha. + - When tor aborts due to an error, close log file descriptors before + aborting. Closing the logs makes some OSes flush log file buffers, + rather than deleting buffered log lines. Fixes bug 31594; bugfix + on 0.2.5.2-alpha. + + o Minor bugfixes (logging, backport from 0.4.2.2-alpha): + - Add a missing check for HAVE_PTHREAD_H, because the backtrace code + uses mutexes. Fixes bug 31614; bugfix on 0.2.5.2-alpha. + - Disable backtrace signal handlers when shutting down tor. Fixes + bug 31614; bugfix on 0.2.5.2-alpha. + - Rate-limit our the logging message about the obsolete .exit + notation. Previously, there was no limit on this warning, which + could potentially be triggered many times by a hostile website. + Fixes bug 31466; bugfix on 0.2.2.1-alpha. + + o Minor bugfixes (logging, protocol violations, backport from 0.4.2.2-alpha): + - Do not log a nonfatal assertion failure when receiving a VERSIONS + cell on a connection using the obsolete v1 link protocol. Log a + protocol_warn instead. Fixes bug 31107; bugfix on 0.2.4.4-alpha. + + o Minor bugfixes (mainloop, periodic events, in-process API, backport from 0.4.2.3-alpha): + - Reset the periodic events' "enabled" flag when Tor is shut down + cleanly. Previously, this flag was left on, which caused periodic + events not to be re-enabled when Tor was relaunched in-process + with tor_api.h after a shutdown. Fixes bug 32058; bugfix + on 0.3.3.1-alpha. + + o Minor bugfixes (multithreading, backport from 0.4.2.2-alpha): + - Avoid some undefined behaviour when freeing mutexes. Fixes bug + 31736; bugfix on 0.0.7. + + o Minor bugfixes (process management, backport from 0.4.2.3-alpha): + - Remove overly strict assertions that triggered when a pluggable + transport failed to launch. Fixes bug 31091; bugfix + on 0.4.0.1-alpha. + - Remove an assertion in the Unix process backend. This assertion + would trigger when we failed to find the executable for a child + process. Fixes bug 31810; bugfix on 0.4.0.1-alpha. + + o Minor bugfixes (relay, backport from 0.4.2.2-alpha): + - Avoid crashing when starting with a corrupt keys directory where + the old ntor key and the new ntor key are identical. Fixes bug + 30916; bugfix on 0.2.4.8-alpha. + + o Minor bugfixes (testing, backport from 0.4.2.3-alpha): + - When testing port rebinding, don't busy-wait for tor to log. + Instead, actually sleep for a short time before polling again. + Also improve the formatting of control commands and log messages. + Fixes bug 31837; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (tests, SunOS, backport from 0.4.2.2-alpha): + - Avoid a map_anon_nofork test failure due to a signed/unsigned + integer comparison. Fixes bug 31897; bugfix on 0.4.1.1-alpha. + + o Minor bugfixes (tls, logging, backport from 0.4.2.3-alpha): + - Log bugs about the TLS read buffer's length only once, rather than + filling the logs with similar warnings. Fixes bug 31939; bugfix + on 0.3.0.4-rc. + + o Documentation (backport from 0.4.2.2-alpha): + - Explain why we can't destroy the backtrace buffer mutex. Explain + why we don't need to destroy the log mutex. Closes ticket 31736. + + o Testing (continuous integration, backport from 0.4.2.3-alpha): + - Disable all but one Travis CI macOS build, to mitigate slow + scheduling of Travis macOS jobs. Closes ticket 32177. + - Run the chutney IPv6 networks as part of Travis CI. Closes + ticket 30860. + - Simplify the Travis CI build matrix, and optimise for build time. + Closes ticket 31859. + - Use Windows Server 2019 instead of Windows Server 2016 in our + Appveyor builds. Closes ticket 32086. + + o Testing (continuous integration, backport from 0.4.2.4-rc): + - In Travis, use Xcode 11.2 on macOS 10.14. Closes ticket 32241. + - Use Ubuntu Bionic images for our Travis CI builds, so we can get a + recent version of coccinelle. But leave chutney on Ubuntu Trusty, + until we can fix some Bionic permissions issues (see ticket + 32240). Related to ticket 31919. + - Install the mingw OpenSSL package in Appveyor. This makes sure + that the OpenSSL headers and libraries match in Tor's Appveyor + builds. (This bug was triggered by an Appveyor image update.) + Fixes bug 32449; bugfix on 0.3.5.6-rc. + + o Testing (continuous integration, backport from 0.4.2.5): + - Require C99 standards-conforming code in Travis CI, but allow GNU gcc + extensions. Also activates clang's -Wtypedef-redefinition warnings. + Build some jobs with -std=gnu99, and some jobs without. + Closes ticket 32500. + Changes in version 0.4.1.6 - 2019-09-19 This release backports several bugfixes to improve stability and correctness.
