Dell Command Update 5.6.0 on OptiPlex 3080's

In the Dell Command Update download page for version 5.6.0, the OptiPlex 3080 is not listed under compatible systems, but the model number prior and after that one are.

I am wondering if anybody has information about this, and whether or not it was a typo? I have successfully updated several 3080's to version 5.6 from 5.5, so it seems odd that this model is not listed in DELL's website.

Thank you.
