-Re: Next releases

I'm glad to see we are converging. I'll update the Roadmap wiki with details about major/minor/patch releases.
Here is a straight-forward approach for now: I'll just roll contents of branch-2.2 as a 2.3-rc0 candidate right-away. This way we don't have to get embroiled in details of individual patches (there are too many). Next up, I'll roll 2.4 in December.

Before this there wasn't such a big contention of what went into patch vs. minor releases and often the lines were blurred between the two. However now we have significant customers and products starting to use 2.x as a base, which means we need to start treating 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.

Then there should be fewer surprises for everyone what ended up in a patch 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.
> As for 2.2.1, again I think it's expectations for what that release means. If 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.
