There really isn't a set procedure yet.

Sometimes after, sometimes before.

You can ask.

Here's how the last 3 "long-term" releases came about:
  .16 - turned out that my employeer was using it for an enterprise
        kernel release, so it made my "day job" a lot easier to keep it
	going for a longer-than-normal period of time.  People liked
	this, so it kept going.
  .27 - Same as before.
  .32 - Now things got interesting.  Some kernel developers who "worked"
        for different distros got together and talked about picking a
	release that their distros could sync up on and become a
	long-term released kernel.  That ended up being the .32 kernel
	and we planned it ahead of time.  This resulted in all of the
	major distros relying on this kernel for their releases.

And that's it.  Pretty simple, but effective.

You can always ask me ahead of time what is going on with this type of
thing, that's the best way.  I am easy to get ahold of if you have
questions like this.

For .32, I did announce this ahead of time, perhaps you missed that.

Hope this helps,
