As noted in this press release, LithTech, Inc. has announced that they have shipped version 3.1 of their LithTech Development System to their engine licensees. There don't seem to be too many whizbang graphical enhancements in this version, but the press release mentions that it contains full Maya support, 3D Studio Max 4 skin support, support for DirectX 8 sound and more. Thanks Digital Silence for the tip. Update: More details on this version can be found in Jason Hall's .plan update.
