You can get NetBeans 6.0.1 from netbeans.org. It's a minor bugfix release with no new features. So what has changed? There are some bugfixes available (see the list here) and also Glassfish v2 UR1 is now officially supported. So no big deal but don't forget the more significant 6.1 release is in the works - beta is coming in a month or so.
