===============================================================================

  * list of changes since 0.10.0

    o Autoloads subtitle files when they have the same name than the video
      being played and are in the same directory.

    o GObject introspection support.

    o Added a new clutter_gst_init_with_arg() symbol, changed *get_playbin()
      to a more generic *get_pipeline()
