This latest Maya release is emphasizing reliability and efficiency instead of flashy new features, a wise choice for a high-end application. The workflow for polygon modeling has been streamlined and is supposedly more efficient, and a few tweaks have been made to the way polygon tools work. The performance of many of the tools has supposedly been increased, and rendering is now faster as well. DirectX HLSL shaders are now supported, which is good news for PS3 or Xbox 360 developers, and Maya's character animation has also gotten a bit better. Like I said, none of these are groundbreaking changes, but Autodesk seems to be doing a good job of streamlining a mature product.
