As the summary says, please stabilize the latest version as new stable. It has been in the tree for 5 months, and I consider it quite stable. I had to remove two of the tests (mail and delete), since they don't seem to work in a sandbox environment. I've no idea why, so if anyone is keen in fixing it, do it. Besides that FEATURES=test emerge =quilt-0.46 should give you more then enough.
