Regular NW Face of Half Dome Free info wanted

Hey there -- my primary valley goal this is to free the NW face of half dome. With recent events, I'm a bit confused and was wondering if anyone can provide any insight. I can't seem to find much, please forgive me if this has already been answered.

1) My main question is how did the rockfall effect the free route.
2) I'm sure there is still some loose rock up there -- does anyone know the extent of this? Are we talking a few crumblies or loose death blocks?

Thanks!
Craig
