File path editor will be handy when moving your projects around to different computers. Node editor improvements look good. Nice... filter for attributes in the Attribute Spreadsheet, no scrolling back and forth forever trying to find that one attribute. Back, Left, Bottom ortho cameras from the panel menu. I know there's been some good scripts for this already, but having a built-in grease pencil looks nice. The bend deformer works in degrees now... that's a bit more intuitive. And they've actually given some attention to paint effects, that's pretty surprising. Skip existing rendered frames could be handy, I guess, but I doubt I'd ever use it. Ooohh... I don't know if this is what I think it is, but there's a new -perframe flag for batch rendering with mental ray. If mental ray does not render your animation correctly, use this flag to re-translate the frames from scratch. This feature is only available for batch rendering. John, does this make your script obsolete?
