Nope. the new docs are for angel rounds. Horowitz makes the point that VC's should act like angels when in an angel round (when in rome).
I anticipate that both docs (YC + Andreessen/Horowitz are very similar. They keep it simple so that shit doesnt get complicated if you make it to an A round.
What's great is that lots of top notch folks have pledged to use them = a standard is upon us.
