We've pushed our first Beta of JBoss Developer Studio 4 to our early access site.

You can download the full Eclipse based IDE from the early access site  for free, and if you want to have the no-fuzz-single-click-install  experience with JBoss Enterprise Application platform bundled you just  need to go and sign up for the early access program here.

This release incorporates the changes and improvements done in JBoss Tools 3.2 Beta1.

Have fun!
