I took my normal Saturday route today and noticed a more frequent nag with beeping noise in the section of road that is missing clear lane markers. Prior versions didn't do this. It seems they might have increased the nag multiplier when AP is less confident of lane lines.
I also got to test NOA and I really like how the new feature to move out of the fast lane works. That said, on another occasion it prompted me to pass a slow car and I gave it the go ahead and it went and then abruptly canceled the lane change for no reason that I could see. If the lane change is deemed safe it needs to commit, the darting out and back into the lane makes you look like an idiot and can be dangerous if other cars are closing the gap.
