John Foderaro announced a new version of the open source Franz code for handling the "deflation" compression scheme (used by zip files and gzip), deflate. (Note that for your convenience and ease of understanding, the deflate module contains a single source file: inflate.cl.) This is a bug-fix release.
Marco Antoniotti let the world know that defsystem 3.3i (see the "Latest File Releases" section) is out. I think this is mostly a bug-fix release for LispWorks users, but frankly the defsystem family tree makes my head hurt and since I don't use defsystem I figured I'd leave it up to you to figure out.
Oh, and now I see that 3.3i.1 (!) is out and available at the same location.
David E. Young announced the "snapshot release" of LISA, a lisp-based production-rule system for creating intelligent software agents.
