I just pushed an update in time for Week 1 here at MFN-1. It's actually pretty huge as I've been watching the tests - punting now will effectively aim to drop the ball inside the 10 yard line (if you're close enough). The coverage team also has the ability to down the ball. I saw several fair catches as well as downing the ball in testing.
The one aspect that I may still look at is the regular punting situations; I'd love to hear feedback on what the punt returns looked like both in situations where the ball is dropped inside the 10, as well as situations that are too far out to do that.
