JUST A REMINDER: 13.1 is the first Ventura update past the 30 day hold for OTA major upgrades for MDM managed macOS devices
If you have devices on 12.3-12.6 still and you DO NOT have a minor deferral in addition to a major deferral - on these buggy versions of macOS (12.6.1+ fixes the bug), 13.1 OTA will be seen as a -minor- update, not major and as such will NOT be deferred by only having a major deferral in place.
1/n
TL;DR: -Only- got a major deferral in place? All your 12.3-12.6 Macs will be offering 13.1 to all of your users TODAY.
If you find yourself in this situation and you do not want this?
Roll out a minor deferral -now-. This minor -will- affect trying to get to 12.6.1 / 12.6.2 but:
12.6.1 came out 50 days ago
Put out a minor less than 50 days and you will still see 12.6.1 on those devices right away, while still holding back 13.1 on the buggy versions since it just came out today.
