-For 0.0.2pre17:

-        o Make cells 512 bytes
-        o Reduce streamid footprint from 7 bytes to 2 bytes
-          X Check for collisions in streamid (now possible with
-            just 2 bytes), and back up & replace with padding if so

-          of a sha1 of the ongoing relay payload (move into stream header)
-        o Move length into the stream header too
-        o Make length 2 bytes
-        D increase DH key length
-        D increase RSA key length

-For 0.0.2pre14:

 Short-term:
+        - if you specify a non-dirserver as exitnode or entrynode, when it
+          makes the first few circuits it hasn't yet fetched the directory,
+          so it warns that it doesn't know the node.
+        - when you hup, rewrite the router.desc file (and maybe others)
+        - consider handling broken socks4 implementations
         - improve how it behaves when i remove a line from the approved-routers files
         - Make tls connections tls_close intentionally
         o Rename ACI to circID
