Here is what I notice so far:
Android Pay works with knock code.
Can toggle silent with volume and vibrate.
Quicker to unlock.
Dialer added video calling option
Battery life seems worse but not by much.
Doze didn't do much(left off the charger overnight for 8hours and went 97% to 87%).
Added most shared to contacts at the top of the share to options.
When making a choice to use an app, the box is not checked that says "use as default app," so now you can just hit ok and it will use the highlighted app. Small change but awesome!
Brightness slider defaults to current brightness when toggled off of auto instead where you set it. Can now toggle 0,50 and 90% though.
Couple things changed in settings like a Google tab, and ram monitoring.
