An additional change I seem to notice is that the Google search bar is no longer getting replaced by “At a glance”. It stays in place beyond midnight (rather than turning into a pumpkin 
) Further discussion here.
If you disable the Google app, then in place of the search bar you get the “At a glance” widget straight away (requires reboot).
I have posted this info here, because it’s about a change brought with the sw update.
