Yes, looks like major enhancements to the V7 radiosity solution - but also even more controls for fine-tuning that (like in the user render type quality adjust "edit" - photon mapping, etc.).
 
A good explanation of photon mapping parameters and such is in Jeremy Birn's "Digital Lighting & Rendering 2nd Edition" book. 

Notice the new Collada 3D model import? I tried it with DAZ Studio (instead of my usual .obj import" and it worked fine. I have V7i.
