While it is mainly a port a few new features are added like an updated interface with artist drawn toolbar (thank you Mason from Germany) and a few other modern tweaks.
ok. that's what i figured. if/when the OS4.x version ships, i'd love to see some benchmarks comparing rendering time of the included sample projects (like the shuttle) on v5.0 and v6.0 to see just how much performance improvement folks could expect. just a suggestion.

thanks for posting the video.
