There was talk of modifying the pano to eliminate the possibility of rainwater coming through it. I'm not sure if that was the only reason for the redesign.
Also changed design of the flip up covers over the rack mounts which have a habit of breaking off pretty easily if they are flipped open.
I've noticed that when going through a touchless car wash, the rack mount covers tend to get flipped open by the waterjets. I wonder if this update is to address that too.
