I have tagged and uploaded JBoss Profiler 2.0 Beta4. Get it from http://www.jboss.org/jbossprofiler/downloads/

Changes over 2.0 Beta3:
* Converted reports to HTML
* Converted documentation to Docbook and included it as PDF in distribution
* Bug-fixes
* Initial build environment (cmake) for native backend (JVMTI/HPROF)

If you want to work on

* Web front-end using JSF / RichFaces
* Native backend (did someone say C ?)
* Documentation / Screenshots

let us know.

Have fun!
