I must say I really like 4.8. The grassType material feature is just awesome.
I’m still missing HeightField GI, or am I mistaken? Would love to use that in combination with my HDRI skylight, since I’m working on a night mission. Any moonlight bounce I can use is welcome 
Also, is it me or did the translucent shader get a big improvement? I’m now able to use it in conjunction with screen space reflections. Maybe that was already a thing in 4.7 though, but it didn’t work there for me.
