I will continue reviewing today

some findings with our env, describe affected was super slow for us 🤷

and from profiling

The expensive part was the pre-plan affected/config evaluation path, which triggered repeated cloud auth/store/state work before planning.

The newer graph binary improves that path substantially: affected preflight went from 21m02s to 1m34s.

(note, @Andriy Knysh (Cloud Posse) has some optimizations that went into this recently as well)

• https://github.com/cloudposse/atmos/releases/tag/v1.220.0 • https://github.com/cloudposse/atmos/pull/2496 @shirkevich 1.220.0 has the improvements

@Andriy Knysh (Cloud Posse) are we set for a release now?

yes, we can release
