   o Major bugfixes (rate limiting):
     - Servers decline directory requests much more aggressively when
       they're low on bandwidth. Otherwise they end up queueing more and
       more directory responses, which can't be good for latency.
+    - Fix a memory leak when sending a 503 response for a networkstatus
+      request.
     - But never refuse directory requests from local addresses.
     - Be willing to read or write on local connections (e.g. controller
       connections) even when the global rate limiting buckets are empty.

   o Major bugfixes (other):
-    - Fix a crash bug in the presence of DNS hijacking (reported by Andrew

     - Previously, we would cache up to 16 old networkstatus documents
       indefinitely, if they came from nontrusted authorities. Now we
       discard them if they are more than 10 days old.

       pointer loops.

     - If exits are rare enough that we're not marking exits as guards,
       ignore exit bandwidth when we're deciding the required bandwidth
       to become a guard.
