Thanks to athaba, netcap, and tvierling.

Changes in version 0.2.0.30 - 2008-07-15
  This new stable release switches to a more efficient directory
  distribution design, adds features to make connections to the Tor
  network harder to block, allows Tor to act as a DNS proxy, adds separate
  rate limiting for relayed traffic to make it easier for clients to
  become relays, fix a variety of potential anonymity problems, and
  includes the usual huge pile of other features and bug fixes.
