give 0.2.3.5-alpha a blurb

Changes in version 0.2.3.5-alpha - 2011-09-28

  Tor 0.2.3.5-alpha fixes two bugs that make it possible to enumerate

  bridge relays; fixes an assertion error that many users started hitting

  today; and adds the ability to refill token buckets more often than

  once per second, allowing significant performance improvements.

  o Security fixes:

    - Bridge relays now do their directory fetches inside Tor TLS

      connections, like all the other clients do, rather than connecting

      directly to the DirPort like public relays do. Removes another

      avenue for enumerating bridges. Fixes part of bug 4115; bugfix

      on 0.2.0.35.

      avenue for enumerating bridges. Fixes bug 4115; bugfix on 0.2.0.35.

    - Bridges relays now build circuits for themselves in a more similar

      way to how clients build them. Removes another avenue for

      enumerating bridges. Fixes bug 4124; bugfix on 0.2.0.3-alpha,

      when bridges were introduced.

  o Major bugfixes:

    - Fix a crash bug that could occur when the same microdescriptor was

      referenced by two node_t objects at once. Fix for bug 4118; bugfix

      on Tor 0.2.3.1-alpha.

    - Fix an "Assertion md->held_by_node == 1 failed" error that could

      occur when the same microdescriptor was referenced by two node_t

      objects at once. Fix for bug 4118; bugfix on Tor 0.2.3.1-alpha.

  o Major features (networking):

    - Add a new TokenBucketRefillInterval option to refill token buckets
