Is there a list of new functionality in 3.0?

I've written for a fairly long time with CI 2.1, I see a lot of fixes or modifications and updating to existing functions in 3.x but no new functionality.

Is that more or less the idea going forward or will we see new classes as well? If so is there a feature list that I can skim instead of reading the docs, I'm pretty familiar with all of the classes I currently use
