    - Just because your DirPort is open doesn't mean people should be

      able to remotely teach you about hidden service descriptors. Now

      only accept rendezvous posts if you've got HSAuthoritativeDir set.

    - When eventdns is enabled, allow multithreaded builds on NetBSD and

      OpenBSD.  (We had previously disabled threads on these platforms

      because they didn't have working thread-safe resolver functions)



  o Major bugfixes, other:

    - Avoiding crashing on race condition in dns.c:
