        - Shared memory areas are no longer restricted to 64K. We now
          detect the maximal size of a shared memory area at runtime.
        - cleanup of the internal uptime API.
 +      - para_server prefaults the mmapped audio file to avoid
 +        delays on slow media.
++      - A new test for the test-suite that exercises the
++        communication between  para_server and para_audiod.
