once the builds leave the internal dev/qa process, they go to a group of about 12 people outside the company (we just added one last week) that are dedicating some pretty serious hours every week to help us with what we call “alpha” testing. the software they get is … uh… less than perfect 
after that, we were hoping to just have 2 tracks of builds… beta and stable. this would be a public beta. its pretty high up the todo list right now to get that going… unfortunately, it has a few things ahead of it: iOS, metadata editing, headless builds for mac/windows, roonspeakers, and linux builds.
for iOS, first we have to get it into the store before we can “alpha”. right now, everyone is provisioned by hand, and we cant do that beyond a handful of devices.
once we submit to apple (not for approval) we can go to a wider group outside the company. was hoping to get that done today, but the holiday is throwing off my plans.
