Before doing anything with version 2 at this point, I would wait until the dust settles on the transition of @researchxxl’s version. The transition from the previous version has not been handled in a manner that inspires trust. For the full story, you can read https://forum.syncthing.net/t/does-anyone-know-why-syncthing-fork-is-no-longer-available-on-github/ but prepare to be confused.
I’m sticking with the older build until the dust settles but you should know that there is some drama right now before installing a program with full device permission using build from another developer.
