+Changes in version 0.4.1.7 - 2019-12-??
+  This release backports several bugfixes to improve stability and
+  correctness.  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.
