The new software for the rear seat entertainment (RSE) is to fix a problem where the RSE can stay in "Programming mode" after flash programming or clearing DTCs.Staying in this mode will flatten the battery over time.
Previously the RSE fuse had to be removed after programming or clearing codes to reset the RSE.
Sorry i couldn't tell you that it removes the region coding or something exciting like that,but your car will be more reliable now.
