Roger Corman has announced that Corman Lisp 2.01 has been released. It can be obtained from the Corman Lisp website. I'd point to the actual message posted to the mailing list but the mailing list archives are down. The release notes explain what is new.
Also on the mailing list, Edi Weitz posts timings comparing v2.01 to v2.00 and shows great improvements in speed for his CL-PPCRE library using the new version of Corman Lisp.
