@@ -24,41 +24,6 @@ x - When we've been idle a long time, we stop fetching server
     until we've fetched correct ones.
 x - If the client's clock is too far in the past, it will drop (or
     just not try to get) descriptors, so it'll never build circuits.

-    o Note that we'd like a better speed-bump too.
-  o Bug 336: CIRC events should have digests when appropriate.
-  o Improve behavior when telling nicknames and digests to controllers.
-    We should give digest, and nickname, with indication of whether name is
-    canonical.
-    o edmanm likes $DIGEST~nickname for unNamed routers, and
-      $DIGEST=nickname for Named routers. So do I.
-    o Make the code accept it where we currently ask for the nickname of
-      another server. Semantics should be strict to start ($D=N means, "give
-      me the Named server with digest D named N"; $D~N means "give me a
-      server with digest D named N".  Nothing else matches.)
-    o Add ability to selectively send 'long' nicknames on v1 connections.
-    o Add a feature to actually turn on the switch.
-    o Implement response for ORCONN.

-    o Verify that everything actually does the right thing.

 N - Clients stop dumping old descriptors if the network-statuses

-    without demanding that exit node.
-    o And recognize when extending to the enclave node is failing,
