Hi Tom,
We’re a little bit behind. I think @Nate_Koenig is going to update the roadmap soon.
In the meantime, I can tell you we’re doing a feature freeze tomorrow unless something slips, and we plan to release beta 2 within a few weeks. I think the current best guess is July 7th.
Also, you can always try our latest builds here:
