My browser has been essentially non-functional in any practical way since I got the car, so I don't bother ever to use it. I did notice that my maps would not follow my position this AM, but hopefully when I go back to it later it will have corrected itself.
The release notes say that you have Spotify (updated?), the maps were updated with miles to searched destinations (old?), you have a Joe mode (updated?), new button positions (updated?), and maybe something else.
