I've put a release candidate for 1.0alpha here:
http://www.bluetail.com/~luke/misc/lisp/slime-1.0alpha.tar.gz
Also slime.ps and slime.pdf (now prettier!) in the same directory.
If you have a moment then please give it a once-over. If nobody finds any serious problems in the next hour or so then we can release it.
I also tagged CVS with SLIME-1-0-ALPHA.
