+Changes in version 0.3.2.5-alpha - 2017-11-22
+  Tor 0.3.2.4-alpha is the fifth alpha release in the 0.3.2.x series. It
+  fixes several stability and reliability bugs, including a fix for
+  intermittent bootstrapping failures that some people have been seeing
+  since the 0.3.0.x series.
+
+  Please test this alpha out -- many of these fixes will soon be
+  backported to stable Tor versions if no additional bugs are found
+  in them.
+
+  o Minor features (directory authority):
+    - Make the "Exit" flag assignment only depend on whether the exit
+      policy allows connections to ports 80 and 443. Previously relays
+      would get the Exit flag if they allowed connections to one of
+      these ports and also port 6667. Resolves ticket 23637.
+
+  o Minor features (geoip):
+    - Update geoip and geoip6 to the November 6 2017 Maxmind GeoLite2
+      Country database.
+
+  o Minor features (linux seccomp2 sandbox):
+    - Update the sandbox rules so that they should now work correctly
+      with Glibc 2.26. Closes ticket 24315.
+
+  o Minor features (logging):
+    - Downgrade a pair of log messages that could occur when an exit's
+      resolver gave us an unusual (but not forbidden) response. Closes
+      ticket 24097.
+    - Improve the message we log when re-enabling circuit build timeouts
+      after having received a consensus. Closes ticket 20963.
+
+  o Minor bugfixes (bootstrapping):
+    - Fetch descriptors aggressively whenever we lack enough to build
+      circuits, regardless of how many descriptors we are missing.
+      Previously, we would delay launching the fetch when we had fewer
+      than 15 missing descriptors, even if some of those descriptors
+      were blocking circuits from building. Fixes bug 23985; bugfix on
+      0.1.1.11-alpha. The effects of this bug became worse in
+      0.3.0.3-alpha, when we began treating missing descriptors from our
+      primary guards as a reason to delay circuits.
+    - Don't try fetching microdescriptors from relays that have failed
+      to deliver them in the past. Fixes bug 23817; bugfix
+      on 0.3.0.1-alpha.
+
+  o Minor bugfixes (compilation):
+    - Fix a memory leak warning in one of the libevent-related
+      configuration tests that could occur when manually specifying
+      -fsanitize=address. Fixes bug 24279; bugfix on 0.3.0.2-alpha.
+      Found and patched by Alex Xu.
+    - When detecting OpenSSL on Windows from our configure script, make
+      sure to try linking with the ws2_32 library. Fixes bug 23783;
+      bugfix on 0.3.2.2-alpha.
+
+  o Minor bugfixes (control port, linux seccomp2 sandbox):
+    - Avoid a crash when attempting to use the seccomp2 sandbox together
+      with the OwningControllerProcess feature. Fixes bug 24198; bugfix
+      on 0.2.5.1-alpha.
+
+  o Minor bugfixes (control port, onion services):
+    - Report "FAILED" instead of "UPLOAD_FAILED" "FAILED" for the
+      HS_DESC event when a service is not able to upload a descriptor.
+      Fixes bug 24230; bugfix on 0.2.7.1-alpha.
+
+  o Minor bugfixes (directory cache):
+    - Recover better from empty or corrupt files in the consensus cache
+      directory. Fixes bug 24099; bugfix on 0.3.1.1-alpha.
+    - When a consensus diff calculation is only partially successful,
+      only record the successful parts as having succeeded. Partial
+      success can happen if (for example) one compression method fails
+      but the others succeed. Previously we misrecorded all the
+      calculations as having succeeded, which would later cause a
+      nonfatal assertion failure. Fixes bug 24086; bugfix
+      on 0.3.1.1-alpha.
+
+  o Minor bugfixes (logging):
+    - Only log once if we notice that KIST support is gone. Fixes bug
+      24158; bugfix on 0.3.2
+    - Suppress a log notice when relay descriptors arrive. We already
+      have a bootstrap progress for this so no need to log notice
+      everytime tor receives relay descriptors. Microdescriptors behave
+      the same. Fixes bug 23861; bugfix on 0.2.8.2-alpha.
+
+  o Minor bugfixes (network layer):
+    - When closing a connection via close_connection_immediately(), we
+      mark it as "not blocked on bandwidth", to prevent later calls from
+      trying to unblock it, and give it permission to read. This fixes a
+      backtrace warning that can happen on relays under various
+      circumstances. Fixes bug 24167; bugfix on 0.1.0.1-rc.
+
+  o Minor bugfixes (onion services):
+    - The introduction circuit was being timed out too quickly while
+      waiting for the rendezvous circuit to complete. Keep the intro
+      circuit around longer instead of timing out and reopening new ones
+      constantly. Fixes bug 23681; bugfix on 0.2.4.8-alpha.
+    - Fix the consensus parameter "hsdir-interval" to "hsdir_interval"
+      so it matches the dir-spec.txt. Fixes bug 24262; bugfix
+      on 0.3.1.1-alpha.
+    - Silence a warning about failed v3 onion descriptor uploads that
+      can happen naturally under certain edge-cases. Fixes part of bug
+      23662; bugfix on 0.3.2.1-alpha.
+
+  o Minor bugfixes (tests):
+    - Fix a memory leak in one of the bridge-distribution test cases.
+      Fixes bug 24345; bugfix on 0.3.2.3-alpha.
+    - Fix a bug in our fuzzing mock replacement for crypto_pk_checksig(),
+      to correctly handle cases where a caller gives it an RSA key of
+      under 160 bits. (This is not actually a bug in Tor itself, but
+      wrather in our fuzzing code.) Fixes bug 24247; bugfix on
+      0.3.0.3-alpha. Found by OSS-Fuzz as issue 4177.
+
+  o Documentation:
+    - Add notes in man page regarding OS support for the various
+      scheduler types. Attempt to use less jargon in the scheduler
+      section. Closes ticket 24254.
