     - Set up moria1 and tor26 as the first v3 directory authorities. See
       doc/spec/dir-spec.txt for details on the new directory design.

+  o Major bugfixes (bridges):
+    - Fix a bug that made servers send a "404 Not found" in response to
+      attempts to fetch their server descriptor. This caused Tor servers
+      to take many minutes to establish reachability for their DirPort,
+      and it totally crippled bridges. Bugfix on 0.2.0.5-alpha.
     - Make "UpdateBridgesFromAuthority" torrc option work: when bridge
       users configure that and specify a bridge with an identity
       fingerprint, now they will lookup the bridge descriptor at the
       default bridge authority via a one-hop tunnel, but once circuits
       are established they will switch to a three-hop tunnel for later
-      connections to the bridge authority.

+  o Major bugfixes (hidden services):
+    - Hidden services were choosing introduction points uniquely by
+      hexdigest, but when constructing the hidden service descriptor
+      they merely wrote the (potentially ambiguous) nickname.
+    - Clients now use the v2 intro format for hidden service
+      connections: they specify their chosen rendezvous point by identity
+      digest rather than by (potentially ambiguous) nickname. Both
+      are bugfixes on 0.1.2.x, and they could speed up hidden service
+      connections dramatically. Thanks to Karsten Loesing.
 
   o Minor features (security):
-    - As a client, do not believe any server that tells us that any address
-      maps to an internal address space.

     - Make it possible to enable HashedControlPassword and
       CookieAuthentication at the same time.
 
   o Minor features (guard nodes):
-    - Tag every guard node in our state file with the version that we believe
-      added it, or with our own version if we add it.  This way, if a user
-      temporarily runs an old version of Tor and then switches back to a new
-      one, she doesn't automatically lose her guards.

   o Minor features (speed):
     - When implementing AES counter mode, update only the portions of the
       counter buffer that need to change, and don't keep separate

        and are obsoleted by TorFlow anyway.

     - Turn "descriptor store" into a full-fledged type.
     - Move all NT services code into a separate source file.
     - Unify all code that computes medians, percentile elements, etc.
