I don’t agree. I think that was just his answer to “out of beta” (who knows) . I think beta can have blockers, also, typically big regressions found in canary or experimental, or maybe a critical fix it’s worth waiting for.
The person who does releases should answer that, but an opinion (hope it’s still valid) on that issue is:
Personally, I think it’s best for canary to have hand-curated documentation on the changes. Takes time.
There’s also some need to keep track of the state of things and not push a release at an unstable spot.
That’s where milestones could help the release-maker. Automated test success is not the total story…
Nightlies might have to make do with GitHub’s list of source changes, unless automation can do better.
