I don't have a copy of the release notes handy but the biggest improvement is to summon which now has a customizable feature to let you set the distance from obstacles as well as how far away the range is for the fob or app to be detected. The best improvement imo is the ability to not have to hold the fob or app button down in order to initiate. It does give you a warning when you enable this. Also, after you download you have to re-enable summon.
