BTW Irrlicht is great so thank you to the author for making it. CobberCube looks good too. But that is one reason someone might not update a project a lot -- they are making other stuff, for example one along the same lines that could make money. But Irrlicht works great still and still has a forum etc. so I would not complain if there weren't more updates.

Actually I wouldn't really want another update at this point, because I already have a code base built on the existing thing that does what I want and adapting to new/changed stuff would distract from developing features specific to my system.
