No, you didn't.
I discussed this with Lars and Tuukka yesterday before leaving for the
airport. We discussed whether we should branch now at RC1, wait until RC2 or
even longer. There are good arguments in both directions:
- if we don't branch now, we risk destabilising changes going in, changes
that should be kept back.
- what's more, if we don't branch now, there's nowhere to put important bug
fixes that just need a little more testing (i.e., the ones for 5.0.1)
- however, if we do branch now, we create work for the release team for
cherry-picking the important fixes or redirecting to the release branch.
So we discussed a judgement call: to us, it looked like we'll need a lot of
necessary fixes on top of RC1 -- some of which we already know, which is why
we're certain there will be an RC2. If we branch now, we create a lot of
additional work. The risk of a regressing change being accepted is worth the
gain in workflow.
We'll create the releases branch for the RC2 then.
