First release in a while! (I'm almost done with the alpha of my new drone scripting language/project so I can work a bit more on Andropilot)

I'm only posting this beta to the github download site (see link in the Andropilot Users Group description). Once I hear some positive test results (please post!) I'll promote this beta to the google play store...
