Check out the impressive list of New and Noteworthy items.
I recommend “bleeding-edge” developers adopt this build as soon as possible to allow for feedback on some of the new stuff that was dropped (e.g., p2, api tools). The Platform team deserves a lot of credit for getting this out the door considering, updating, building, launching, self-hosting, exporting etc… all had to be reworked for the new provisioning story.
Cheers!
