The first release candidate of Mixminion 0.0.5 is now available.

This release candidate adds features to Mixminion 0.0.4; everyone
running a server should upgrade.

   Source: http://mixminion.net/dist/Mixminion-0.0.5rc1.tar.gz
Signature: http://mixminion.net/dist/Mixminion-0.0.5rc1.tar.gz.asc
   README: http://mixminion.net/dist/README-0.0.5rc1

The most significant changes are:

   - Support for email headers.  'Subject', 'In-Reply-To', and 'References'
     are fully supported.  'From' support is limited, as documented in
     'E2E-spec.txt'.

   - Limited support for K-of-N message fragmentation and reassembly.  Right
     now, clients can send large fragmented messages for servers to
     reassemble them.  Not yet supported are independent paths, fragmented
     reply messages, and client-side fragment reassembly.

   - UI improvements
      - Path generation can now create random-length paths
      - Support for removing old messages from client queues.
      - 'Mixminion shell' command to wrap other commands on platforms with
        iffy terminals or shells.  Poor substitute for a real GUI.

   - Improved portability
      - All client and server functionality works properly on Cygwin.
      - Everything should work on win32 too.  (But it won't be supported till
        I can get Py2Exe working.)
      - The build system should work on more unixes.

   - Improved configurability
      - Support for suppressing directory permission messages.

   - Improved performance
      - Server RAM usage should be way down, except while reassembling large
        messages.

   - Improved testability
      - Server descriptors now describe the server's platform and
        configuration. 

   - Bugfixes too numerous to mention.  Server pools in general should be
     significantly more robust.
