Yes I think they’re meaning they’re still adding lots of new features possibly, but it is a bit confusing as I think of Alpha as raw and not production ready. Beta can be ready for testing with brand new features, and stable is usually production ready and all features already passed beta testing. I get it is for home use but still. Maybe they’re covering themselves legally, but then you can just say “use at your own risk”. It’s possible too they don’t have separate branches at all, and just add/update/fix the “alpha” version.
