-  o Major bugfixes (controller):
-    - Make wildcarded addresses (that is, ones beginning with *.) work when
-      provided via the controller's MapAddress command.  Previously, they
-      were accepted, but we never actually noticed that they were wildcards.

-  o Minor bugfixes:
-    - Downgrade "set buildtimeout to low value" messages to INFO
-      severity; they were never an actual problem, there was never

-  o Security fixes:
-    - Tear down the circuit if we get an unexpected SENDME cell. Clients
-      could use this trick to make their circuits receive cells faster
-      than our flow control would have allowed, or to gum up the network,
-      or possibly to do targeted memory denial-of-service attacks on
-      entry nodes. Fixes bug 6252. Bugfix on the 54th commit on Tor --
-      from July 2002, before the release of Tor 0.0.0.  We had committed
-      this patch previously, but we had to revert it because of bug 6271.
-      Now that 6271 is fixed, this appears to work.

-  o Minor bugfixes:

-    - Remove the maximum length of microdescriptor we are willing to

-    - Move log message when unable to find a microdesc in a

-  o Major bugfixes:
-    - Detect 'ORPort 0' as meaning, uniformly, that we're not running

-      presence of any ORPort line as meaning that we should act like a
-      server, even though our new listener code would correctly not
-      open any ORPorts for ORPort 0. Similar bugs in other Port
