Media mapping, projection mapping, real-time rendering, probably compatibility with various projectors, tools for distortion correction and alignment. Since it's version 3.7.4, there might be some updates from previous versions. The CE part might indicate it's a version optimized for a certain audience—maybe Creative Edition? Or Community Edition?
