• babashka: native, fast starting Clojure interpreter for scripting.
  • Support self-contained binaries as uberjars!
  • Add java.security.KeyFactory, java.security.spec.PKCS8EncodedKeySpec, java.net.URISyntaxException
  • Fix babashka.process/exec wrt babashka.process/*defaults*

  • SCI: optimize swap!, deref and reset! for normal atoms (rather than user-created IAtoms)
• sci.configs: A collection of ready to be used SCI configs.
  • A configuration for hoplon and javelin was added. You can play around with hoplon in a SCI-enabled environment here
• clj-kondo: static analyzer and linter for Clojure code that sparks joy.

  • #344: macros can't be used via aliases
  • Add squint.edn support, see docs
  • Add watch subcommand to watch :paths from squint.edn
  • Make generated let variable names in JS more deterministic, which helps hot reloading in React
  • Added a vite + react example project.
  • Resolve symbolic namespaces (:require [foo.bar]) from :paths
  • Add bit-and and bit-or
  • Include lib/squint.core.umd.js which defines a global squint.core object (easy to use in browsers, see docs)

• deps.clj: A faithful port of the clojure CLI bash script to Clojure
  • Get home directory via environment variable rather than system property by @DerGuteMoritz, thanks!
• babashka.nrepl: The nREPL server from babashka as a library, so it can be used from other SCI-based CLIs
