Version 9 is an early beta or even alpha and there will be changes. But in it's present form it is clearly a Major update, starting with new, much improved interface, support for audio for dailies work and deliverables. Resolve will have an option for single render, multiple deliverables. In other words, you'll be able to set up a single render with something, like prores, h264, dnxhd, all in one render. Very cool. Audio syncing in auto mode, based on TC or manually. Bringing images with sound imports them as separate video and sound files. And finally for die hard colorists- Log grading! Metadata settings are not burried anymore, but are next to the timeline and live. Metadata settings are per shot and even per version. Yes, you can have different metadata settings for different versions of the grade. iObviously, there is much more, but that's what I can remember.
