Re: 0.4 and GitHub, all of our changes to add 0.4 support are in a branch that we’re working on with Oculus.
The timing of the 0.4 Beta SDK release was very close to our locking down for the 4.4 release, and since 0.4 is a beta, we wanted to ensure stability by not slotting in a beta SDK at the last minute.
That said, 0.4 has plenty of awesome changes, so we want to figure out a way to get that to folks, likely via GitHub at first. Hopefully we’ll have more news on that shortly.
