Yeah it's just renamed, it's Color Attribute now and Face Corner and other totally different names. Remember, the hassle of going through that headache is not worth it, it is much better to download the Blender version Kent is using in the video and you go smooth sailing with it.
Yes YYoda,
Color Attribute it now is!
When you come to add the node in the shader, Shift+A > Attribute > Dirty Verts.
If you rename to Dirty Verts of course.
