Actually, ShipIt released itself. Read about it.
One will note that it's tagged, uploaded, has no omissions in its MANIFEST, ChangeLog, etc. ShipIt wouldn't let me release it without double-checking a few dozen things.
I'm not sure I'd recommend using this yet for your projects, as I'm not even using it yet for anything besides ShipIt, but I will be soon. Like, probably later today.... I've got a whole bunch of patches in my inbox in addition to a bunch of projects with committed but unreleased changes.
Patches welcome, if you find yourself using it! But mostly I made it for me, to get my other stuff out quicker.
