      . The event loop is now based on GLib's main loop library instead of
      . For Android platforms, the server now sends buffer fence fds to its
        clients instead of potentially stalling the compositor thread waiting
        for them to be signalled.
      . New client debug interface to translate from surface to screen
    - ABI summary: Servers need rebuilding, but clients do not;
      . Mirclient ABI unchanged at 8
      . Mircommon ABI bumped to 3
      . Mirplatform ABI bumped to 4
      . Mirserver ABI bumped to 27
    - Bug fixes:
      . Add a debug interface to translate from surface to screen coordinates
        (LP: #1346633)
      . Ensure a buffer requested by a surface is not delivered
        after the surface is deleted (LP: #1376324)

      . Server aborts when an exception is thrown from the main thread
        (LP: #1378740)
      . Fix race causing lost alarm notifications (LP: #1381925)
      . Avoid lifecycle notifications racing with connection release
        (LP: #1386646)
      . Improve error checking and reporting for the client library
       (LP: #1390388)
      . Mir demo-shell now detects power button using proper Linux scan codes
       (LP: #1303817)
      . A prompt session with an invalid application pid should be an error
        (LP: #1377968)
      . When XDG_RUNTIME_DIR is defined but pointing to a non-existing
        directory use "/tmp" (LP: #1304873)

        there are windowed surfaces behind (LP: #1378706)
