Author here. Babashka is a native Clojure interpreter for scripting, it starts in ~5-20ms instead of the usual JVM startup. This release adds JLine3 for building TUIs, a completely revamped console REPL, and a bunch of library compatibility improvements. The charm.clj counter example in the post is a single-file script you can run right away to get an idea of the new TUI capabilities. Have fun scripting!
This is not about maintaining compatibility with a Java version. As you can read in the post, Java 21 will be the minimum required Java version even. It's about the Google Closure Library on which many ClojureScript programs depend.
