One side note, something extremely interesting (at least in my opinion). When you rendered an spherical image in previous version of vue and saved them as HDR image, if you opened them in HDR Shop, the maximum values you got when hovering over the sun (dangerous, ask the Icarus guy about it :) ), now, they are above 15 which is much closer to the values you get with a real HDR image of good quality. This is most certainly a side effect of the new implementation :)
