+- Fixed: DSBarInfo::DrawGem() crashed if chain or gem was NULL.
+- Fixed: Sound sequences are not thinkers, therefore they must be explicitly
+  marked as roots for the GC.
 - Reduced the range that area sounds require to interpolate between 2D and
   3D panning.
 - The listener's velocity is now set at 0 for the sound engine. The player
