Changes to the Cyrus IMAP Server since 2.1.11

      * Master now has a daemon mode and pidfile support (-d and -p
        options)
      * Berkeley DB Configuration methods have changed. Hopefully they're

      * timsieved now handles usernames with dots (when unixhierarchysep is
        active)
      * tugowar has been removed from the distribution.
      * Squatter now has an option to skip unmodified mailboxes.
      * Properly hash username to remove a user's sieve scripts when their
        INBOX is removed.
      * Reset output buffer when prot_flush returns EOF.
      * Minor Makefile improvements with use of $(srcdir)
      * Remotepurge improvement for empty mailboxes
      * Fix for AFS overwriting the canonicalized username in ptloader
