I send out the all clear.

Done. I've renamed 2.3 -> 2.4 and 2.2.1 -> 2.3.

I'll create the first RC for 2.3 a week from now i.e. 12/9.

thanks,
Arun

it like we treat 1.x.  That means getting serious about what we should put into a patch release
vs. what we postpone to a minor release.

release and less likely the patch release becomes destabilized from the sheer amount of code
churn.  Maybe this won't be necessary if everyone understands that the patch release isn't
the only way to get a change out in timely manner.

it's really just a patch release then there shouldn't be features in it and tons of code churn,
but I think many were treating it as the next vehicle to deliver changes in general.  If we
think 2.2.1 is just as good or better than 2.2.0 then let's wrap it up and move to a more
disciplined approach for subsequent patch releases and more frequent minor releases.
