+Changes in version 0.4.1.2-alpha - 2019-06-05
+  Tor 0.4.1.2-alpha resolves numerous bugs--some of them from the previous
+  alpha, and some much older. It also contains minor testing improvements,
+  and an improvement to the security of our authenticated sendme
+  implementation.
+
+  o Major bugfixes (bridges):
+    - Consider our directory information to have changed when our list of
+      bridges changes. Previously, Tor would not re-compute the status of its
+      directory information when bridges changed, and therefore would not
+      realize that it was no longer able to build circuits. Fixes part of bug
+      29875.
+    - Do not count previously configured working bridges towards our total of
+      working bridges. Previously, when Tor's list of bridges changed, it
+      would think that the old bridges were still usable, and delay fetching
+      router descriptors for the new ones.  Fixes part of bug 29875; bugfix
+      on 0.3.0.1-alpha.
+
+  o Major bugfixes (Flow Control, SENDME):
+    - The decrement of the stream-level package window was done in a log_debug()
+      statement meaning that if the debug logs were not enabled, the decrement
+      would never happen and thus the window would be out of sync with the other
+      end point. Fixes bug 30628; bugfix on 0.4.1.1-alpha.
+
+  o Major bugfixes (Onion service reachability):
+    - Properly clean up the introduction point map and associated state when
+      circuits change purpose from onion service circuits to pathbias,
+      measurement, or other circuit types. This should fix some instances of
+      introduction point failure. Fixes bug 29034; bugfix on 0.3.2.1-alpha.
+
+  o Minor features (authenticated SENDME):
+    - Ensure that there is enough randomness on every circuit
+      to prevent an attacker from successfully predicting what SENDME cells
+      they will need to send: at a random interval, if we have not send
+      randomness already, leave some extra space at the end of a cell that
+      we can fill with random bytes.  Closes ticket 26846.
+
+  o Minor features (continuous integration):
+    - When running coverage builds on Travis, we now set TOR_TEST_RNG_SEED,
+      to avoid RNG-based coverage differences.
+      Part of ticket 28878.
+
+  o Minor features (maintenance):
+    - Add a new "make autostyle" target that developers can use to
+      apply all automatic Tor style and consistency conversions to the
+      codebase. Closes ticket 30539.
+
+  o Minor features (testing):
+    - The circuitpadding tests now use a reproducible RNG implementation,
+      so that if a test fails, we can learn why. Part of ticket 28878.
+    - Tor's tests now support an environment variable, TOR_TEST_RNG_SEED,
+      to set the RNG seed for tests that use a reproducible RNG.
+      Part of ticket 28878.
+    - When running tests in coverage mode, take additional care to make
+      our coverage deterministic, so that we can accurately track changes in
+      code coverage. Closes ticket 30519.
+
+  o Minor bugfixes (configuration, proxies):
+    - Fix a bug that prevented us from supporting SOCKS5 proxies that want
+      authentication along with configured (but unused!)
+      ClientTransportPlugins. Fixes bug 29670; bugfix on 0.2.6.1-alpha.
+
+  o Minor bugfixes (controller):
+    - POSTDESCRIPTOR requests should work again. Previously, they were
+      broken if a "purpose=" flag was specified.  Fixes bug 30580;
+      bugfix on 0.4.1.1-alpha.
+    - Repair the HSFETCH command so that it works again. Previously, it
+      expected a body when it shouldn't have. Fixes bug 30646; bugfix on
+      0.4.1.1-alpha.
+
+  o Minor bugfixes (developer tooling):
+    - Fix pre-push hook to refrain from rejecting fixup and squash commits
+      when pushing to non-upstream git remote. Fixes bug 30286; bugfix on
+      0.4.0.1-alpha.
+
+  o Minor bugfixes (directory authority):
+    - Move the "bandwidth-file-headers" line in directory authority votes
+      so that it conforms to dir-spec.txt. Fixes bug 30316; bugfix on
+      0.3.5.1-alpha.
+
+  o Minor bugfixes (NetBSD):
+    - Fix usage of minherit() on NetBSD and other platforms that define
+      MAP_INHERIT_{ZERO,NONE} instead of INHERIT_{ZERO,NONE}. Fixes bug
+      30614; bugfix on 0.4.0.2-alpha. Patch from Taylor Campbell.
+
+  o Minor bugfixes (out-of-memory handler):
+    - When purging the DNS cache because of an out-of-memory condition,
+      try purging just the older entries at first.  Previously, we would
+      purge the whole thing. Fixes bug 29617; bugfix on 0.3.5.1-alpha.
+
+  o Minor bugfixes (portability):
+    - Avoid crashing in our tor_vasprintf() implementation on systems that
+      define neither vasprintf() nor _vscprintf(). (This bug has been here
+      long enough that we question whether people are running Tor on such
+      systems, but we're applying the fix out of caution.) Fixes bug 30561;
+      bugfix on 0.2.8.2-alpha. Found and fixed by Tobias Stoeckmann.
+
+  o Minor bugfixes (shutdown, libevent, memory safety):
+    - Avoid use-after-free bugs when shutting down, by making sure that we
+      shut down libevent only after shutting down all of its users. We
+      believe these are harmless in practice, since they only occur on the
+      shutdown path, and do not involve any attacker-controlled data. Fixes
+      bug 30629; bugfix on 0.4.1.1-alpha.
+
+  o Minor bugfixes (static analysis):
+    - Fix several spurious Coverity warnings about the unit tests, to lower our
+      chances of missing any real warnings in the future. Fixes bug 30150;
+      bugfix on 0.3.5.1-alpha and various other Tor versions.
+
+  o Testing:
+    - Specify torrc paths (with empty files) when launching tor in
+      integration tests; refrain from reading user and system torrcs.
+      Resolves issue 29702.
+

 Changes in version 0.4.1.1-alpha - 2019-05-22
   This is the first alpha in the 0.4.1.x series. It introduces
   lightweight circuit padding to make some onion-service circuits harder
