Not sure how many people would notice, but a big change occurred in the "estimated miles remaining at end of journey" reading. As of the last update (.42) I noticed a large improvement. I live at 9,000 ft. elevation just inside of the Rockies near the flatlands. Yesterday (my first trip up the hill after the update) I noticed it predicted my car would lose 53 miles of range on the 16-mile drive home. It's estimate was off by only ONE mile. Previously this was NOT the case. Now I'm preparing to go back down the hill and I put it in my navigation screen and it predicts I'll arrive at my destination with 23 MORE miles than is currently on the range indicator(!). This means that the nav software now takes in to account elevation changes. It's a 3,700 ft. climb to my house from town. It used to predict I'd lose only the 17 miles in the climb and, of course, there would be lots less on the clock when I got home. Not the case anymore. Cudos to the team for working this out.
Also, I lose all media services when I go on to those mountains (no cell service). It feels like they turned up the buffering because my media keeps playing much longer when I lose cell service than pre-update. All thumbs up on this update so-far, including activation of that previously un-used display section that let's us see music AND navigation when we're using both.
