Dispersion in Cycles

Are there any plans to add dispersion to Cycles anytime soon? I miss the Brazil where it was fast and passable. Speaking of which, does it (Brazil) work with Rhino 7? I assume it is no longer to purchase additional licenses…

Not anytime soon.

But in the mean time there are other render engines out there that probably have what you are looking for: Bella, Maverick, etc.
