Since the new annotations are used in these tutorials, you must use NetBeans Platform 6.7 if you want to create projects via these tutorials. (Using the 'old' way is not much different, though. Replace the annotations by appropriate META-INF/services and/or layer entries.)
There could be mistakes still, at this point. Typos or otherwise. Feel free to tell me so. Feedback of any kind is welcome, as always.
