That very question has been the cause of a number of sleepless nights.
Expect a commercial 1.0 release in September/October. This will include a few new features and allow time for some rigurous testing.
I'll be forking the project in a few weeks and will start working on major new features for 1.1. For those looking forward to those features, expect to see new beta versions appear not long after the commercial release of 1.0.
