OptiX on Pascal cards

Hi there,
can I ask you when you release OptiX version with support for new Pascal cards (1080, 1070)?
I assume, that OptiX 3.9 release is closed, so first version with Pascal cards support will be OptiX 4.0. However OptiX 4.0 doesn’t have support for Fermi cards now, so is it planned Fermi cards support with final release or support for these cards is definitively closed?
Thanks for any response

Hi Smejkal, we’ve just released OptiX 3.9.1. which includes Pascal support. OptiX 4.0 will support Pascal as well, but will drop Fermi.
