The major change to this version is the addition of a scene cutter. Select a vertical cutting plane by pressing the crossed swords button and selecting two points on the scene. The portion in front of a left-to-right selection is hidden from vertically below the line - the portion closest to the camera is thus removed. To recover the full scene, press the crossed swords button again and right click on the scene. This functionality should solve some of the requests I received, let me know if it is working for you.
