The last update was at August 19th 2007, with a lot of additions to the last build. The project is still active, although news flow slowly into the main website.
In the words of the team:
"Sorry... Yes, we really should update more. While major development has progressed on and off this past year (as with most open-source projects, when RealLife[tm] permits), we *have* continued working. We tend to focus the time we can spend on Nuvie on actual code work (and sometimes idle chat), neglecting the website until there is quite a bit to report."
