A good chunk of functionality is implemented. I've been daily driving niri for at least two months now. I feel like it's a good point to make the first tag.
Make no mistake, this is an alpha tag. There are known bugs and missing features. Don't be surprised if there's a breaking config change in the future. But, depending on your needs and preferences, it may already be good enough for daily use.
Please check the README for building and installation instructions. Also, if you're on Fedora, I've got a COPR.
For people following along, I recommend sticking to the main branch rather than freezing on this release.
