I don't think another version was released yet.  The UI sneak peek had some working functionality however.  Take a step back though.  XChat and the mixer still are not working for me and many others.  I'm ready and available to provide details and testing.  Seems like quite a bit of testing would need to be done if it's spanning across 3 platforms.  Adding mobile to the eco-system before the 3 main platforms are solid seems odd.  I've had multiple software Q&A jobs in my lifetime so I speak from some experience.
