I've released version 0.8 of FunctionalJ. This version is, hopefully, an improvement to the API as well as the welcome addition of a JDK-1.5 version that uses generic types and other nice 1.5 features.
I wanted to thank Geert for JHighlight, which I used for syntax colouring of the code examples in the documentation. Cool stuff! 
There is a news item on TheServerSide.
Cheers,
Frederic
