For reasons that are not entirely clear, JSS was not working with the images I published for abcl-1.1.0, even though building from the source on the tag worked fine.
I have re-published and re-signed the release to common-lisp.net.
Still sort of waiting for Quicklisp 2012-12 to drop before mailing an official announcement. Maybe we should just wait for abcl-1.1.1 at this point.
mea culpa, Mark
