During EclipseCon we released JBoss Developer Studio 3
JBoss Developer Studio provides a single-install of a full Eclipse based development environment which includes Eclipse 3.5, productized subset of JBoss Tools 3.1, TestNG, SpringIDE and an (optional) bundled JBoss Enterprise Application Platform 5.
JBoss Developer Studio is for those who would like to just install and IDE and get work done without the hassle of configuring Eclipse and related runtimes.
If you are into JBoss SOA, Portal or the Enterprise Webserver platforms JBoss Developer Studio 3 supports these too and the JBoss Developer Studio Portfolio Edition product gives you access to these.
Information about installation and migration from previous JBoss Developer Studio versions are available from JBoss Developer Studio 3 page.
Have fun!
