Just for clarity what changed was the default shading methods on some of the Cycles native nodes. The ones affecting EZSkin were the GlossBSDF and SubsurfaceScatterBSSDF. The change to Gloss will remain because it makes the default the same on WIndows and Mac. The change to SSS was unintended fallout. The default will be returned to it's original (Burley) in the next SR.

Again this is only the default values when the shaders are added to a material. This change won't affect existing scenes or library materials.
