When we switched to using v3 directories, we threw away the part of 

the "do we have enough directory info?" calculation that checked
how many relays we believed to still be running based on our own
experience. So if we went offline, we never gave up trying to make
new circuits; worse, when we came back online we didn't recognize
that we should give all the relays another chance. Bugfix on
0.2.0.9-alpha; fixes bugs 648 and 675.

Changes in version 0.2.1.1-alpha - 2008-??-??

  o Major bugfixes:

    - When we switched to using v3 directories, we threw away the part of

      the "do we have enough directory info?" calculation that checked

      how many relays we believed to still be running based on our own

      experience. So if we went offline, we never gave up trying to make

      new circuits; worse, when we came back online we didn't recognize

      that we should give all the relays another chance. Bugfix on

      0.2.0.9-alpha; fixes bugs 648 and 675.



  o Minor bugfixes:

    - Stop giving double-close warn when we reject an address for client DNS.

    - On Windows, correctly detect errors when listing the contents of a

src/or/routerlist.c
