You need to set HOMEBREW_NO_UPGRADE_AUTO_UPDATES_CASKS to 1, as alluded to by a hint when it (first?) occurs. This means if you have hints off (via HOMEBREW_NO_ENV_HINTS) then I suspect you can start getting this behavior without warning which is a bummer.

I read this as "This means if you close your eyes you don’t see things, which is a bummer."

When you instruct the system not to tell you things, the system not telling you those things is a bummer?
If I could get more of the tech I interact with to stop doing things I didn't ask it to, it would reduce a lot of stress and wasted time.
Ah, I suppose I did word that poorly—I more mean that a significant breaking change (Casks that previously were documented as being excluded from auto-updating suddenly being auto-updated) which can occur silently is a rough end-user experience, even if the user explicitly opted into hiding hints.

Yes this is intended. We skip those that seem to have already auto-updated underneath. Our code for this is not yet rock solid so please file issues for those you notice are not doing the right thing here.
I noticed that homebrew updated _all_ my casks when running 'brew upgrade' (even those with "auto_updates: true" in their Cask JSON API).
Is this intended, new default behavior? This did not use to happen...
