On behalf of the developers of ABCL (Armed Bear Common Lisp) I'm glad to be able to announce the 0.24.0 release. ABCL is a Common Lisp implementation implemented in Java and running on the JVM, featuring both an interpreter and a compiler. The compiler targets the JVM directly meaning that its output is runnable JVM bytecode. The fact that ABCL is written in Java allows for relatively easy embedding in larger applications. For integration with existing applications ABCL implements JSR 223: Java scripting API. This release features - among lots of other things - improved embedding support through elimination of System.exit() calls and fixes a regression causing FASLs to be limited in the number of functions they can contain.
