Carousel 4.5.2 Release Notes
=========================================================

      * Bug 635 | Loss of BG audio over extended period of time.
-The audio handler would sometimes quit and would never recover (when running from the "line-in" source).  The DisplayEngine now checks to see if the audio handler is still around, and will start it back up if it goes missing.

      * Bug 921 | Instrumentation doesn't work unless you turn on "TraceComponents"
-Before, you could only see what the service was up to if it was already set up for debugging.  Now, the service can be monitored at all times.

      * Bug 926 | Default installed database structure is out of date
-After a fresh install of 4.5.1, the database structure needed to be updated.  This release includes an up-to-date version of the database.

      * Bug 927 | Carousel Service mistakenly sets 'Saved' bulletins to 'Stale'
-The new database procedures was turning all bulletins to Stale if they were out of date.  Now, we only set Active or Queued bulletins to Stale (if they are out of date, of course).

      * Bug 936 | Database update screen can unauthenticate users
-There was a rare condition that occured when the current database structure was out of date. Users would be immediately logged-out when they tried to access Carousel and they did not have access to the database tools screen.

      * Bug 956 | Video bulletins allow an audio file to be attached
-When an audio file was attached to a video bulletin, the audio file and the video's audio track would run on top of each other.

      * Bug 991 | Spelling error on About screen
-"Tightrope" is now spelled correctly.  Yikes.

      * Bug 1007 | Fallback code in DE for unsupported hardware plus support for GMA950
-Display Engine now runs in standard mode with the Intel GMA950 graphics chipsets, and will fall back to crossfade-only when run either on unsupported hardware or in unsupported resolutions.
