   o Major features:
     - Tor now tracks how long it takes to build client-side circuits
       over time, and adapts its timeout to local network performance.

       to EDGE and find out if the build-time data in the .tor/state gets
       reset without loss of Tor usability. You should also see a notice
       log message telling you that Tor has reset its timeout.
-    - Authorities can now vote on arbitary integer values as part of the
-      consensus process. This is designed to help set network parameters.
-      Implements proposal 167.
+    - Directory authorities can now vote on arbitary integer values as
+      part of the consensus process. This is designed to help set
+      network-wide parameters. Implements proposal 167.
     - Tor now reads the "circwindow" parameter out of the consensus,
       and uses that value for its circuit package window rather than the
       default of 1000 cells. Begins the implementation of proposal 168.
 
+  o Major bugfixes:
+    - Fix a remotely triggerable memory leak when a consensus document
+      contains more than one signature from the same voter. Bugfix on
+      0.2.0.3-alpha.
+
   o Minor bugfixes:
     - Fix an extremely rare infinite recursion bug that could occur if
       we tried to log a message after shutting down the log subsystem.
       Found by Matt Edman. Bugfix on 0.2.0.16-alpha.
     - Fix parsing for memory or time units given without a space between
-      the number and the unit.  Bugfix on 0.2.2.1-alpha; fixes bug 1076.
+      the number and the unit. Bugfix on 0.2.2.1-alpha; fixes bug 1076.
     - A networkstatus vote must contain exactly one signature. Spec
       conformance issue. Bugfix on 0.2.0.3-alpha.
+    - Fix an obscure bug where hidden services on 64-bit big-endian
+      systems might mis-read the timestamp in v3 introduce cells, and
+      refuse to connect back to the client. Discovered by "rotor".
+      Bugfix on 0.2.1.6-alpha.
+    - We were triggering a CLOCK_SKEW controller status event whenever
+      we connect via the v2 connection protocol to any relay that has
+      a wrong clock. Instead, we should only inform the controller when
+      it's a trusted authority that claims our clock is wrong. Bugfix
+      on 0.2.0.20-rc; starts to fix bug 1074. Reported by SwissTorExit.
+    - We were telling the controller about CHECKING_REACHABILITY and
+      REACHABILITY_FAILED status events whenever we launch a testing
+      circuit or notice that one has failed. Instead, only tell the
+      controller when we want to inform the user of overall success or
+      overall failure. Bugfix on 0.1.2.6-alpha. Fixes bug 1075. Reported
+      by SwissTorExit.
+    - Don't warn when we're using a circuit that ends with a node
+      excluded in ExcludeExitNodes, but the circuit is not used to access
+      the outside world. This should help fix bug 1090. Bugfix on
+      0.2.1.6-alpha.
+    - Teach connection_ap_can_use_exit to respect the Exclude*Nodes config
+      options. Should fix bug 1090. Bugfix on 0.0.2-pre16.
+    - Work around a small memory leak in some versions of OpenSSL that
+      stopped the memory used by the hostname TLS extension from being
+      freed.
+
+  o Minor features:
+    - Add a "getinfo status/accepted-server-descriptor" controller
+      command, which is the recommended way for controllers to learn
+      whether our server descriptor has been successfully received by at
+      least on directory authority. Un-recommend good-server-descriptor
+      getinfo and status events until we have a better design for them.
