Another popular early project was Jonathon Fowler's "JFDuke3D", which, in December 2003, received backing from the original author of Build, programmer Ken Silverman. Fowler, in cooperation with Silverman, released a new version of "JFDuke3D" using Polymost, an OpenGL-enhanced renderer for Build which allows hardware acceleration and 3D model support along with 32-bit color high resolution textures. Another project based on "JFDuke3D" called "xDuke", unrelated to the "xDuke" project based on "Duke3d_w32", runs on the Xbox. Silverman has since helped Fowler with a large portion of other engine work, including updating the network code, and helping to maintain various other aspects of the engine. Development appears to have stopped; as of January 2015, there have been no new versions since October 9, 2005.
