+Changes in version 0.4.2.2-alpha - 2019-10-0?
+ This release fixes several bugs from the previous alpha release.
+
+ o Major bugfixes (embedded Tor):
+ - 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 (torrc):
+ - 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 Minor features (authority):
+ - 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 Minor features (auto-formatting scripts):
+ - When annotating C macros, never generate a line that our check-spaces
+ script would reject. Closes ticket 31759.
+ - When annotating C macros, try to remove cases of double-negation.
+ Closes ticket 31779.
+
+ o Minor features (continuous integration):
+ - When building on Appveyor, pass the "-k" flag to make, so that
+ we are informed of all compilation failures, not just the first
+ one or two. Closes part of ticket 31372.
+ - When building on Travis, pass the "-k" flag to make, so that
+ we are informed of all compilation failures, not just the first
+ one or two. Closes part of ticket 31372.
+
+ o Minor features (geoip):
+ - Update geoip and geoip6 to the October 1 2019 Maxmind GeoLite2
+ Country database. Closes ticket 31931.
+
+ o Minor features (maintenance scripts):
+ - Add a coccinelle script to detect bugs caused by incrementing or
+ decrementing a variable inside a call to log_debug(). Since
+ log_debug() is a macro whose arguments are conditionally evaluated, it
+ is usually an error to do this. One such bug was 30628, in which SENDME
+ cells were miscounted by a decrement operator inside a log_debug()
+ call. Closes ticket 30743.
+
+ o Minor features (onion services v3):
+ - Assist users who try to setup v2 client authorization in v3 onion
+ services by pointing them to the right documentation. Closes ticket
+ 28966.
+
+ o Minor bugfixes (Appveyor CI):
+ - Avoid spurious errors when Appveyor CI fails before the install step.
+ Fixes bug 31884; bugfix on 0.3.4.2-alpha.
+
+ o Minor bugfixes (best practices tracker):
+ - When listing overbroad exceptions, do not also list problems,
+ and do not list insufficiently broad exceptions. Fixes bug 31338;
+ bugfix on 0.4.2.1-alpha.
+
+ o Minor bugfixes (controller protocol):
+ - Fix the MAPADDRESS controller command to accept one or more
+ arguments. Previously, it required two or more arguments, and ignored
+ the first. Fixes bug 31772; bugfix on 0.4.1.1-alpha.
+
+ o Minor bugfixes (logging):
+ - 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.
+ - When initialising log domain masks, only set known log domains.
+ Fixes bug 31854; bugfix on 0.2.1.1-alpha.
+
+ o Minor bugfixes (logging, protocol violations):
+ - 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 (modules):
+ - Explain what the optional Directory Authority module is, and what
+ happens when it is disabled. Fixes bug 31825; bugfix on 0.3.4.1-alpha.
+
+ o Minor bugfixes (multithreading):
+ - Avoid some undefined behaviour when freeing mutexes.
+ Fixes bug 31736; bugfix on 0.0.7.
+
+ o Minor bugfixes (relay):
+ - 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 (tests, SunOS):
+ - 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 Code simplification and refactoring (onion services):
+ - Interface for function `decrypt_desc_layer` cleaned up. Closes ticket 31589.
+
+ o Code simplification and refactoring:
+ - Refactor connection_control_process_inbuf() to reduce the size of a
+ practracker exception. Closes ticket 31840.
+ - Refactor the microdescs_parse_from_string() function into smaller
+ pieces, for better comprehensibility. Closes ticket 31675.
+ - Use SEVERITY_MASK_IDX() to find the LOG_* mask indexes in the unit
+ tests and fuzzers, rather than using hard-coded values.
+ Closes ticket 31334.
+
+ o Documentation:
+ - Document the signal-safe logging behaviour in the tor man page. Also
+ add some comments to the relevant functions. Closes ticket 31839.
+ - Explain why we can't destroy the backtrace buffer mutex. Explain why
+ we don't need to destroy the log mutex.
+ Closes ticket 31736.
+ - The Tor source code repository now includes a (somewhat dated)
+ description of Tor's modular architecture, in doc/HACKING/design.
+ This is based on the old "tor-guts.git" repository, which we are
+ adopting and superseding. Closes ticket 31849.
