On behalf of the developers of ABCL (Armed Bear Common Lisp) I'm glad to be able to announce the 1.0.1 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 Java Specification Request (JSR) 223: Java scripting API. This release squashes bugs in the ABCL 1.0 release, most notably it features a working ABCL-CONTRIB symbol to the ANSI REQUIRE mechanism and it ships with ASDF 2.019.
