* Passes renamed to samples * Camera lens radius renamed to aperature size/blades/rotation * Glass and fresnel nodes input is now index of refraction * Glossy and velvet fresnel socket removed * Mix/add closure node renamed to mix/add shader node * Blend weight node added for shader mixing weights There is some version patching code for reading existing files, but it's not perfect, so shaders may work a bit different.
