This includes much improved GPU rendering performance, viewport interactivity, new shadow catcher, revamped sampling settings, subsurface scattering anisotropy, new GPU volume sampling, improved PMJ sampling pattern, and more. Some features have also been removed or changed, breaking backwards compatibility. Including the removal of the OpenCL backend, for which alternatives are under development. Release notes and code docs: https://wiki.blender.org/wiki/Reference/Release_Notes/3.0/Cycles https://wiki.blender.org/wiki/Source/Render/Cycles Credits: * Sergey Sharybin * Brecht Van Lommel * Patrick Mours (OptiX backend) * Christophe Hery (subsurface scattering anisotropy) * William Leeson (PMJ sampling pattern) * Alaska (various fixes and tweaks) * Thomas Dinges (various fixes) For the full commit history, see the cycles-x branch. This squashes together all the changes since intermediate changes would often fail building or tests. Ref T87839, T87837, T87836 Fixes T90734, T89353, T80267, T80267, T77185, T69800
