Thanks Julia and everyone for handling this situation while I was out. More
comments inline.

Yep :( So, I think the lesson to learn is to create our stable/XXX branch
at the
same time as the other projects. We kind of knew that already, but did not
anticipate such a huge breakage so quickly. I suggest we don't try it in
Queens :)
Now, with that in place we still have two options:
1. A conservative one - make the branching the hard feature freeze, similar
to
other projects. We may start with a soft freeze at around M3, and just move
into
Queens when stable/queens is created. As that point, what is out - is out.
2. Alternative - continue making selected feature backports until the final
freeze roughly one week before the final release. This kind of contradicts
calling a branch "stable" though.
I don't have a strong opinion, but I'm slightly more in favor of the
conservation option #1 to avoid confusing people and complicating the
process.
Thoughts?
Personally, I think option 2 still makes sense, and it aligns us closely with
the process in the other projects, the difference between us and them is that
their branch is cut using a release candidate instead of a real release. The
act of backporting things into the stable branch and then re-releasing is the
same though.
Another alternative I wonder if we should consider is cutting our branch
earlier in the cycle, when we make our first intermediary release, and then
finding out if we can sync the branches at each release time instead of
backporting everything. E.g. git checkout stable/X, git reset –hard
origin/master or git rebase master, git push. Doing this will allow us to
retain the git history and same commit ids from master to stable/X until master
stops developing stable/X and moves on to stable/X+1. I think another advantage
of this is it also allows people to find and use our latest intermediary
releases easier. But I don’t know how nicely this would work with all the
tooling etc the release team has in place.

++ I've approved a few patches already, and will continue approving them
today.

Right, I think we will request it on Wednesday, to allow a bit more time to
test
our newly populated not-so-stable stable/pike :)
