To help me get to grips with the new enhancements, I've documented them in a format that lets me easily compare one Tree against another.
It also lets me print them out and scribble notes on them, and it gives me something to search for things like PRR, dodge, etc etc etc.
The wiki is still the best source of detail on these, but I like a schematic view of the trees. One advantage of having the enhancements in a single document is that if you do search for keywords then it's only new enhancements that will come up.
I've tried to keep the terminology consistent to make searching easy, but inevitably there will be a typo or three that I've not found yet.

I'll revise it with any corrections, please feel free to post any in this thread and I'll periodically update the document.
Having spent some time with this version and previous versions of it, it still doesn't give you the same feel as actually putting a build together to see where some of the constraints come in.
