     - We no longer look for identity and onion keys in "identity.key" and
       "onion.key" -- these were replaced by secret_id_key and
       secret_onion_key in 0.0.8pre1.
+    - We no longer require unrecognized directory entries to be preceded by
+      "opt".
 
   o Security bugfixes:
     - Stop sending the HttpProxyAuthenticator string to directory

+    - Start uploading short and long descriptors; authorities should support
+      URLs to retrieve long descriptors, and should discard short descriptors
+      for now.  Later, once tools use the "long descriptor" URLs, authorities

 Topics to think about during 0.1.2.x development:
   * Figure out incentives.
