Internal change to not apply the shape keys to the Mesh vertex coordinates, but rather use it as part of the derivedmesh/displist evaluation. This only has one practical advantage right now, which is that you can now make a linked duplicate and pin it's shape key to a different shape than the first object. Further, this makes shape keys correctly fit into the modifier stack design, which will help implement some other features later. Also it means the mesh vertex coordinates are now really the orco's.
