For a long time they did weekly releases, which explains the “hundreds” of releases. It looks like they have made enough progress to move to periodic point releases. (I should probably take another look at it.)
I’m not qualified to judge the language as a whole, at least until I use it for something, but it does have some interesting features. I used to follow their progress, but it’s clear that the pace of development is very slow, like many other niche langs.
