==> " We’re working with Unity to update Unity 5.x to 0.7 so that Unity 5.x users don’t have any additional work."

I would like to know which Unity version will support 0.7? Is it already on the road for coming beta versions?
"Extended Mode" is replaced with the new "Direct Driver Mode" which seems to be much faster, how...
