I used to contribute to the authors Patreon, and used to contribute PRs. But I stopped a while back as the author has abandoned the project. The last commit in git was five years ago. (Look at the subreddit if you don't think this has been abandoned)

That's one of the reasons I really dislike year-less blog posts. The most recent blog entry just reads "(Mar 28)". The first assumption would be the current year.
