@hiento09 Approved to unblock. Can I check my understanding:

• This covers only Nightly builds
• We have a separate pipeline for Beta release candidates (e.g. rc1, rc2)
• We have a separate pipeline for Stable releases

@hiento09 Approved to unblock. Can I check my understanding:

• This covers all versions (e.g. Stable, Beta release candidates, and Nightly builds) and not just nightly?

Ah, I add noti for nightly only, beta and stable version we use announcement discord channel I think.
