+  Tor 0.2.3.8-alpha fixes some crash and assert bugs, including a
+  socketpair-related bug that has been bothering Windows users. It adds
+  support to serve microdescriptors to controllers, so Vidalia's network
+  map can resume listing relays (once Vidalia implements its side),
+  and adds better support for hardware AES acceleration. Finally, it
+  starts the process of adjusting the bandwidth cutoff for getting the
+  "Fast" flag from 20KB to (currently) 32KB -- preliminary results show
+  that tiny relays harm performance more than they help network capacity.

   o Major bugfixes:
     - Initialize Libevent with the EVENT_BASE_FLAG_NOLOCK flag enabled, so
       that it doesn't attempt to allocate a socketpair. This could cause

+    - Remove the artificially low cutoff of 20KB to guarantee the Fast
+      flag. In the past few years the average relay speed has picked
+      up, and while the "top 7/8 of the network get the Fast flag" and
+      "all relays with 20KB or more of capacity get the Fast flag" rules
+      used to have the same result, now the top 7/8 of the network has
+      a capacity more like 32KB. Bugfix on 0.2.1.14-rc. Fixes bug 4489.
