It has some alterations on some graphics. New buttons in some places (when I say button is just some shortcuts in some areas to be more fast.) Like for instance, the air purifier option didn't have a virtual button to tap, you had to just tap the logo but know there is a specific button to tap). Another difference is when choosing driving modes, the battery percentage shows in the middle. One change that was awesome is regarding the maps. Before I had to manually go into the navigation menu in the infotainment to show on the drivers dash screen. Now it automatically shows whithout having to trigger it.
Overall the software is smoother.
The lagginess when you first star the car is still there, but it's very improved.
