There’s some history behind it. First the author didn’t want to have it open source, iirc due to some bad experiences with having their source code open? Don’t remember exactly. The repo you linked existed for bug reporting basically. Then later on this changed and the source code got released. I still don’t know if the author is interested in getting public contributions to the codebase.
Regardless, the author makes some very pleasant software, and is super responsive at fixing issues/implementing feature requests. Hats entirely off to them.



Under semantic versioning, you should really be ashamed of bumping the major number, since this means you went and broke backwards compatibility in some way.
