These days it's more a case of "when it's not broken by everything else we're doing". I load state of the build releases from time to time and they're generally getting better, but almost always with some annoying breakage in a specific area.
When our new projects calm down a bit (e.g. go RC) we should get a chance to clean up the problems and release something. I'm not sure what new features might suddenly appear (fewer than those inherited from Karma I would think) but there should be something.
