We have just put a first developer preview of the new RHQ 4 UI online.
This preview is NOT intended FOR PRODUCTION or serious testing, but should rather be seen as an insight on what we are working on.
To learn more about the preview, visit the release notes page from where you can also download it.
As always feedback is very welcome (this includes patches and other code submissions) -- check the contributions page.
If you want to use RHQ for more more serious work, please use RHQ 3.
