Tor 0.1.1.20 is released

Tor 0.1.1.20, the first stable release of the 0.1.1.x branch, is
finally ready.

This release features some major security fixes, including entry guards
to protect the beginning of the circuit, exit enclaves to protect the
end, and better firewall support; a new directory protocol that improves
bandwidth use and keeps clients more up to date; two new directory
authorities; a new ascii-based controller protocol that lets people
easily write applications to interact with Tor; and many scalability
and performance improvements.

Changes in version 0.1.1.20 - 2006-05-23
  o Crash and assert fixes from 0.1.0.17:
    - Fix assert bug in close_logs() on exit: when we close and delete
      logs, remove them all from the global "logfiles" list.
    - Fix an assert error when we're out of space in the connection_list
      and we try to post a hidden service descriptor (reported by Peter
      Palfrader).
    - Fix a rare assert error when we've tried all intro points for
      a hidden service and we try fetching the service descriptor again:
      "Assertion conn->state != AP_CONN_STATE_RENDDESC_WAIT failed".
    - Setconf SocksListenAddress kills Tor if it fails to bind. Now back
      out and refuse the setconf if it would fail.
    - If you specify a relative torrc path and you set RunAsDaemon in
      your torrc, then it chdir()'s to the new directory. If you then
      HUP, it tries to load the new torrc location, fails, and exits.
      The fix: no longer allow a relative path to torrc when using -f.
    - Check for integer overflows in more places, when adding elements
