Chaos presented the new iteration for Corona 10.
We already saw some of the news on sneak peaks, and a lot of the features look similar to what we saw on vray recently.
Faster 3dsmax materials creation (they claim its 22x faster), sunlight color affect clouds, improved caustics, improved bokeh, improvements on motion blur, Decals with multiple maps affecting different channels, lists for cameras and lights, no problem now with the camera flying through volumes, and a long list of other features and improvements that you can read on their blog.
