Jovibarba?

What happened to genus Jovibarba? It became subgenus of Sempervivum?
And why there are no variations of Sempervivum heuffelii listed in the site? I know at least 2 :  Sempervivum heuffelii var. heuffelii and Sempervivum heuffelii var. patens, but probably my information is quite old.
Please enlighten me on this topic or share links where I can read about it.

Thank you for the links! I only can not agree with the other statement. I've seen both plants in the wild and they look completely different (almost difficult to believe that they are actually classified as one species)
var. heuffelii is with green leaves, on both sides with glandular trichomes
var. patens is with glaucous leaves, and trichomes only on the leaf margin
Also they are geographically separated, so I'm sure they deserve to be treaten as varieties.
