+Changes in version 0.3.1.4-alpha - 2017-06-29
+  Tor 0.3.1.4-alpha fixes a path selection bug that would allow a client
+  to use a guard that was in the same network family as a chosen exit
+  relay. This is a security regression; all clients running earlier
+  versions of 0.3.0.x or 0.3.1.x should upgrade to 0.3.0.9
+  or 0.3.1.4-alpha.
+
+  This release also fixes several other bugs introduced in 0.3.0.x
+  and 0.3.1.x, including others that can affect bandwidth usage
+  and correctness.
+
+  o New dependencies:
+    - To build with zstd and lzma support, Tor now requires the
+      pkg-config tool at build time. (This requirement was new in
+      0.3.1.1-alpha, but was not noted at the time. Noting it here to
+      close ticket 22623.)
+
+  o Major bugfixes (path selection, security):
+    - When choosing which guard to use for a circuit, avoid the exit's
+      family along with the exit itself. Previously, the new guard
+      selection logic avoided the exit, but did not consider its family.
+      Fixes bug 22753; bugfix on 0.3.0.1-alpha. Tracked as TROVE-2016-
+      006 and CVE-2017-0377.
+
+  o Major bugfixes (compression, zstd):
+    - Correctly detect a full buffer when decompressing a large zstd-
+      compressed input. Previously, we would sometimes treat a full
+      buffer as an error. Fixes bug 22628; bugfix on 0.3.1.1-alpha.
+
+  o Major bugfixes (directory protocol):
+    - Ensure that we send "304 Not modified" as HTTP status code when a
+      client is attempting to fetch a consensus or consensus diff, and
+      the best one we can send them is one they already have. Fixes bug
+      22702; bugfix on 0.3.1.1-alpha.
+
+  o Major bugfixes (entry guards):
+    - When starting with an old consensus, do not add new entry guards
+      unless the consensus is "reasonably live" (under 1 day old). Fixes
+      one root cause of bug 22400; bugfix on 0.3.0.1-alpha.
+
+  o Minor features (bug mitigation, diagnostics, logging):
+    - Avoid an assertion failure, and log a better error message, when
+      unable to remove a file from the consensus cache on Windows.
+      Attempts to mitigate and diagnose bug 22752.
+
+  o Minor features (geoip):
+    - Update geoip and geoip6 to the June 8 2017 Maxmind GeoLite2
+      Country database.
+
+  o Minor bugfixes (compression):
+    - When compressing or decompressing a buffer, check for a failure to
+      create a compression object. Fixes bug 22626; bugfix
+      on 0.3.1.1-alpha.
+    - When decompressing a buffer, check for extra data after the end of
+      the compressed data. Fixes bug 22629; bugfix on 0.3.1.1-alpha.
+    - When decompressing an object received over an anonymous directory
+      connection, if we have already decompressed it using an acceptable
+      compression method, do not reject it for looking like an
+      unacceptable compression method. Fixes part of bug 22670; bugfix
+      on 0.3.1.1-alpha.
+    - When serving directory votes compressed with zlib, do not claim to
+      have compressed them with zstd. Fixes bug 22669; bugfix
+      on 0.3.1.1-alpha.
+    - When spooling compressed data to an output buffer, don't try to
+      spool more data when there is no more data to spool and we are not
+      trying to flush the input. Previously, we would sometimes launch
+      compression requests with nothing to do, which interferes with our
+      22672 checks. Fixes bug 22719; bugfix on 0.2.0.16-alpha.
+
+  o Minor bugfixes (defensive programming):
+    - Detect and break out of infinite loops in our compression code. We
+      don't think that any such loops exist now, but it's best to be
+      safe. Closes ticket 22672.
+    - Fix a memset() off the end of an array when packing cells. This
+      bug should be harmless in practice, since the corrupted bytes are
+      still in the same structure, and are always padding bytes,
+      ignored, or immediately overwritten, depending on compiler
+      behavior. Nevertheless, because the memset()'s purpose is to make
+      sure that any other cell-handling bugs can't expose bytes to the
+      network, we need to fix it. Fixes bug 22737; bugfix on
+      0.2.4.11-alpha. Fixes CID 1401591.
+
+  o Minor bugfixes (linux seccomp2 sandbox):
+    - Permit the fchmod system call, to avoid crashing on startup when
+      starting with the seccomp2 sandbox and an unexpected set of
+      permissions on the data directory or its contents. Fixes bug
+      22516; bugfix on 0.2.5.4-alpha.
+    - Fix a crash in the LZMA module, when the sandbox was enabled, and
+      liblzma would allocate more than 16 MB of memory. We solve this by
+      bumping the mprotect() limit in the sandbox module from 16 MB to
+      20 MB. Fixes bug 22751; bugfix on 0.3.1.1-alpha.
+
+  o Minor bugfixes (logging):
+    - When decompressing, do not warn if we fail to decompress using a
+      compression method that we merely guessed. Fixes part of bug
+      22670; bugfix on 0.1.1.14-alpha.
+    - When decompressing, treat mismatch between content-encoding and
+      actual compression type as a protocol warning. Fixes part of bug
+      22670; bugfix on 0.1.1.9-alpha.
+    - Downgrade "assigned_to_cpuworker failed" message to info-level
+      severity. In every case that can reach it, either a better warning
+      has already been logged, or no warning is warranted. Fixes bug
+      22356; bugfix on 0.2.6.3-alpha.
+    - Demote a warn that was caused by libevent delays to info if
+      netflow padding is less than 4.5 seconds late, or to notice
+      if it is more (4.5 seconds is the amount of time that a netflow
+      record might be emitted after, if we chose the maximum timeout).
+      Fixes bug 22212; bugfix on 0.3.1.1-alpha.
+
+  o Minor bugfixes (process behavior):
+    - When exiting because of an error, always exit with a nonzero exit
+      status. Previously, we would fail to report an error in our exit
+      status in cases related to __OwningControllerProcess failure,
+      lockfile contention, and Ed25519 key initialization. Fixes bug
+      22720; bugfix on versions 0.2.1.6-alpha, 0.2.2.28-beta, and
+      0.2.7.2-alpha respectively. Reported by "f55jwk4f"; patch
+      from "huyvq".
+
+  o Documentation:
+    - Add a manpage description for the key-pinning-journal file. Closes
+      ticket 22347.
+    - Correctly note that bandwidth accounting values are stored in the
+      state file, and the bw_accounting file is now obsolete. Closes
+      ticket 16082.
+    - Document more of the files in the Tor data directory, including
+      cached-extrainfo, secret_onion_key{,_ntor}.old, hidserv-stats,
+      approved-routers, sr-random, and diff-cache. Found while fixing
+      ticket 22347.
