There have been a ton of releases since then. It looked like a pretty interesting project at the time. It made me want to look for a project to use it for but I never got around to it.
I'd be interested to hear from people who have been using it and how keeping up with the releases has been (compatibility / breaking changes in API, ease of migration, issues, etc).
I use Go so all I have to do is `go get -u` and `go mod tidy` and then it's upgraded. It works great.
I guess for some reason I was hoping for source code that was only one file.
