Yesterday marked the
official release of
Clojure 1.0. After several years of heavy development, the 1.0 branch will enable people to consume a stable version of Clojure and move to bugfix-only incremental versions while preserving API stability. Clojure was produced over the course of a self-funded sabbatical by it's author, Rich Hickey, and aims to provide a modern Lisp running on the JVM with excellent support for concurrency and Java interoperability.
