The ray differential widening for the texture cache blurred out caustics both from procedural textures and image textures. The widening helps reduce texture cache memory, but is also fundamentally biased. The solution now is to tie this to the Filter Glossy setting that must already be lowered from the default to make caustics work. When left at the default the texture cache will be most efficient, when set to small value or zero there will be little or no widening. So this setting now becomes a more general bias control for shading after a rough glossy or diffuse bounce, and the tooltip was updated.
