I have realized that #Phandroid so far used the wrong upstream-branch.
I have used this finding to change the way releases are handled.
There are now 2 release channels:
1. Manually tested standard releases (Phandroid, using the stable production-branch of #Phanpy)
2. fully automatic dev-Releases (Phandroid Dev, main-branch)
If you do nothing, the setup will continue to provide you with stable releases, just less frequently.
Optionally you can install Dev (side-by-side, dedicated settings).
