"There's still no bumpmap or texture functionality in this release, but I've tried to fix some of the issues people have brought up. The main improvements are performance, tool quality, new materials, bugfixed rendering, and some additional controls for navigation.

The new materials will only be visible if your graphics processor supports shaders."
