Ticket 18 was what added all of the new types for 2.2: http://svn.mpi-forum.org/trac2/mpi-forum-web/ticket/18

See also ticket 171, which was a patch for a botched size in external32: http://svn.mpi-forum.org/trac2/mpi-forum-web/ticket/171

You'll need to make sure that whatever you add will work OK with the new RMA text as well.
