Tor 0.2.0.30 is released

Tor 0.2.0.30 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, fixes a variety
of potential anonymity problems, and includes the usual huge pile of
other features and bug fixes.

Changes in version 0.2.0.30 - 2008-07-15
  o New v3 directory design:
    - Tor now uses a new way to learn about and distribute information
      about the network: the directory authorities vote on a common
      network status document rather than each publishing their own
      opinion. Now clients and caches download only one networkstatus
      document to bootstrap, rather than downloading one for each
      authority. Clients only download router descriptors listed in
      the consensus. Implements proposal 101; see doc/spec/dir-spec.txt
      for details.
    - Set up moria1, tor26, and dizum as v3 directory authorities
      in addition to being v2 authorities. Also add three new ones:
      ides (run by Mike Perry), gabelmoo (run by Karsten Loesing), and
      dannenberg (run by CCC).
    - Switch to multi-level keys for directory authorities: now their
      long-term identity key can be kept offline, and they periodically
      generate a new signing key. Clients fetch the "key certificates"
      to keep up to date on the right keys. Add a standalone tool
      "tor-gencert" to generate key certificates. Implements proposal 103.
    - Add a new V3AuthUseLegacyKey config option to make it easier for
      v3 authorities to change their identity keys if another bug like
