This is really a massive release with many cool new features
My personal favorite is add-libs
You can now write single file demos or minimal examples for issues. Really lowers the friction to share small runnable snippets with people
You can also actually use it to demo Java libraries as well without all the Java boilerplate. Just poke around in the REPL and paste code into a comment on HN or wherever and anyone can replicate your "setup" and get it running exactly the same. No need to clone a repo or anything
