Anonymous CVS access is also available for the very features. I'm always running stumpwm from CVS, which means it should be pretty stable. Here is what you need to type:
cvs -d:pserver:anoncvs@cvs.savannah.nongnu.org:/cvsroot/stumpwm login (just press return for the password) cvs -z3 -d:pserver:anoncvs@cvs.savannah.nongnu.org:/cvsroot/stumpwm co stumpwm
