My unlocked Note 8 got the Nov 1 security update this morning. (Arizona)
Apparently, it is similar, if not the same, as the Verizon update detailed at the link below. I can confirm I have the yellow "live focus" notification and the new back button at the top of the camera screen.

(I don't see any recent post about the unlocked update)
