-  o Minor features (relay):
-    - If a circuit timed out for at least 3 minutes check if we have a new
-      external IP address the next time we run our routine checks. If our
-      IP address has changed, then publish a new descriptor with the new
-      IP address. Resolves ticket 2454.
+  o Major features (relay performance):
+    - Faster server-side lookups of rendezvous and introduction point
+      circuits by using hashtables instead of linear searches over all
+      the circuits. These functions previously accounted between 3 and
+      7% of CPU usage on some busy relays.

-  o Minor bugfixes (build):

-  o Minor bugfixes (misc):
     - Resolve some memory leaks found by coverity in the unit tests,
       on exit in tor-gencert, and on a failure to compute digests
       for our own keys when generating a v3 networkstatus vote.
       These leaks should never have affected anyone in practice.
