More rigor around fixing regressions in any release branch.

[Fishrock123]

I think it is probably a good idea to not hold up releases at all if possible to fix API-breaking regressions in any (Major) branch where fixing it would be reasonable to do on a technical level.

This should include mondays and fridays but not weekends.

Perhaps we can state this somewhere?

That sounds like a great idea - imo it's ideal if the fix lands in the same minor in which it was introduced (LTS, or not, it should be treated with the same respect/quality/rigor).
