Correct that ths is offtopic.
Please start a separate discussion on this. This thread needs to remain dedicated to the discussion of the MacOS wrapper in case @xor-gate decides to work on it further and has questions or information.
The release version of syncthing-macos bundles syncthing 1.30.0-1. There’s a v2 branch, which may be what you’re referring to, that bundles 2.0.11-1.
These are very good questions and I’m hoping @calmh might have an opinion. I appreciate that syncthing is a federation of volunteers developers and that there is no “mandate” on what syncthing-macos should do, but it’s a confusing thing that the “official” macOS bundle isn’t tracking the major update.
