2017~2024 infotainment system update question

:
Mazda CX-5 GT 2017
Took my 2017 in for service today to a dealer work order says

"update 59.00.446, 59.00.545A"

1. None of my custom settings on infotainment system/car seem to have changed. Is this normal?

2. Anybody know if there are any surprises in this update I should be aware of?

Thanks
 
The -A at the end surely indicates a minor revision. So yea, probably more like a patch than an update.
Probably bug fix.
 
So how long can you get a new CX-5 updated and how long did you have to leave your car at the dealer?

They listed it a "Under Warranty" and the price was right $0. Im guessing as long as its under 3 year warranty? Had schedule 2 maintenance, state inspection sticker and tires rotated. Dealership had me out of there in 1.5 hours.

Scheduling the appointment was a bit of a trick. All of them were from 8 days to 4 a weeks out. In the old days they used to do first come first serve. Showing my age.
