I wanted to give it a try and headed over to the GitHub repo to find out that the code hasn’t been touched in 3+ years
According to its Github, the code was last updated 5 months ago.
the compiled tarball doesn’t exist anymore
The tarball seems to be alive and well (see the “Releases” section), but the last release is dated June 2020.
While I share your sentiment regarding the seeming lack of updates (see this post) and would love to hear something from the maintainer, your post is full of flat-out misinformation of the worst sort–stuff that one could verify by just looking at the Github. Or maybe we’re somehow talking about different things.
I also want to bring up the possibility that a microkernel, by its miniscule nature (tarball is 2.04 MB), doesn’t need frequent updating and the recent updates are enough. If you want these updates, you’ll have to compile them yourself instead of relying on the tarball though.
