Looks like they took away the setting to only check for updates 1/wk. the notifications for reboots show an estimate of 1/day - that is pretty crazy for a "stable" release, IMO. I've just disabled notifications for system updates altogether. Now I have a feeling that anytime I reboot my phone, I'll just be waiting a significantly longer period of time for any updates to finish installing and apps to refactor or whatever they do.

The release is stable, as a security and privacy focused OS as soon as patches and updates are available and are implemented into the OS we push them to you to maintain protection.
Unlike stock or other OSes we don't leave people auffering issues where we can resolve them first. Take the recent package installer regression in QPR1 where we issued the following:
Android 14 QPR1 has some regressions for the package installer interface. They were aware of these issues for months and they're already fixed in the QPR2 Beta. It's unfortunate their release process is too slow to incorporate fixes, largely defeating the purpose of beta testing.
GrapheneOS will have another OS update later today with fixes for these issues. Stock Pixel OS users will hopefully only need to wait for the January monthly release to resolve the package installer interface crashes. They need to fix many things about their release processes.
