I just sent out Beta version 3 of StarCluster 3. It adds a number of new things, fixes some small problem areas in chargen, clarifies some things better, and includes the beginnings of the Developers Support for the Developer's Edition. I still have to word the license and add some more stuff in the Developer's Notes. Aside from that, fixing the Index is the biggest task left before proofing.
I'm still planning on releasing SC 3 at the end of September/Beginning of October. Barring some catastrophe, I should be able to make that deadline.
