Colour Up 2.0 in-wall body system

What's the difference between traditional (first generation) and color up 2.0 products?

Color up 2.0 products include all shower mixers need to be installed into the wall at the first stage of the job (shower wall mixer, shower wall mixer with diverter, shower wall mixer with spout)
The in-wall body of normal wall shower mixer comes with the cover can not be removed pre or post installation, see picture below.
