When was the CSL Elite Wheel Base V1.1 released?

The "CSL Elite Wheel Base V1.1" was released mid 2019.
It was the successor of the original "CSL Elite Wheel Base" (V1) and therefore PC and (combined with the right steering wheels) Xbox compatible.

The "CSL Elite Wheel Base +" was very similar but Playstation compatible as well.

Looks of the CSL Elite Wheel Base V1.1:

The most obvious visual difference to the CSL Elite Wheel Base + (= CSL Elite Racing Wheel - officially licensed for PS4) is the Fanatec logo on the side panel of the Wheel Base which was not present on the Playstation compatible version.
To identify the product the full and precise product name can always be found on the product label on the bottom of the product.
