On behalf of the developers of ABCL (Armed Bear Common Lisp) I'm glad to
be able to announce the 0.20.0 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
Java Specification Request (JSR) 223: Java scripting API.

This release is the first to include a funded feature: funds were provided
to implement the CLOS METACLASS feature and tests. Next to that,
this release contains a large number of fixes and improvements, such
as the ability to use JARs and URLs as pathnames and the a new ASDF
version (ASDF2). You can find the full release notes at:
