I just read it on Websphere-World: IBM Rational just released version 7 of their development tooling! This features full support for Websphere 6.1 (yes the version numbers are different again), is based on Eclipse 3.2 and Java 5. A lot of improvements in performance and new features are promised. You can read something about the new stuff in IBM Rational Software Architect 7 here. Something about Rational Application Developer is said here, and Functional Tester 7 is explained here. Most of the articles are very basic though, I guess I'll have to try out the tools myself to see what really changed.
IBM released a lot of new products and RAD 6 didn't support them. This new release of the tools should bring support back on track, and should make the tools feel nice and shiny again... At least until Sun releases Java 6... ;)
