Is this for all iOS 15 devices or just the ones not getting iOS 16?

I suspect this will be like iOS 14.8, and you'll be able to choose if you want to install 16.0 or 15.7.

The firmware codenames or "build trains" are:
14.5: AzulE
14.6: AzulF
14.7: AzulG
14.8: AzulSecuritySky
15.5: SkyF
15.6: SkyG
15.7: SkySecuritySydney
16.0: Sydney

So it seems like a similar pattern, 14.8 was "iOS 14 with security updates backported from iOS 15", and 15.7 is "iOS 15 with security updates backported from iOS 16".

If anyone's wondering how to see the macOS 12.6 RC, install the Profile for Ventura, but then select Other Updates and it'll come up there. I was also offered a new Safari Seed, not the Tech Preview.

Once completed, remove the profile by reverting back to Default settings under Software updates. If there's a new build when it's officially released, you'd still get that, otherwise you'd be on it anyway...
Thank you. I’m installing it right now
