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 Java Specification Request (JSR) 223: Java scripting API.
This release features - among lots of other things - CLOS thread safety fixes and concurrency improvements, support for Oracle's JRockit JVM, and a new (generic) class file writer. In addition, this is the first release to complete the Maxima test suite without failures, thanks to close cooperation between our projects. You can find the full release notes at:
