Which is the correct MV Unitheme layout?

I think since the last CS-Cart/Unitheme update a new layout appeared.
Should I use the new “UniTheme 2 (…) - ult10” or the old "UniTheme 2 (…) - mv8 for CS-Cart Multi-Vendor (4.18)?
I’m not sure if the new layout is also made for MV or just for the normal CS-Cart version.
Best regards
