The rule is, no new features.  Bug and security fixes from now on.

It isn't always clear whether or not something is a new "feature".  In the case of such ambiguity, the decision is up to the sole discretion of the release manager.

If you seriously want to check in this thing (*sigh*), I'll take a look at it.  But you'll have to point me at either a patch that applies cleanly to trunk, or a repository somewhere online with the patch already applied to trunk.

Something like a code refactor is probably okay during betas, but during RCs I would really prefer we keep checkins strictly to a minimum.
