Back to the OP's title and request. The way I read this it is a early release of a Public Beta of MF3.0 for 100 testers. Beta testing (my XP days for M$) that I'm aware of requires at least a month or more and trouble reports are then processed and problems fixed for a final Release Candidate. Since the request was made on 11/10/14 and the MF 3.0 App was posted on 11/17/14 that leaves 7 days 5 of which are Apple processing for the App store. I doubt if any changes (show stoppers) for your efforts are included as eluded to. So what was released is a PUBLIC BETA and should be treated as such. No respected company would put out a product without the documentation for the product, none exists as of this post further reinforcing the fact that this is a PUBLIC BETA treat it as such. As it turns out debug code is in this version (now being indicated as a Dropbox problem) which can certainly slow response times.
Update there is now a manual, congrats Mackie.
