The latest version of Steel Bank Common Lisp is out and available at the usual place. The new version has some bug fixes and minor enhancements (see the NEWS page for details) so it represents the ongoing refinement of the environment that the developers have been working on for some time. The package just keeps getting better and better.
As always, the system compiled and ran the tests without problems on my OS X 10.9.4 systems. As I say every month, if you're looking for an excellent Common Lisp package that is under continuous development, you should definitely try out SBCL. It's an outstanding package.
