I thought that the latest version is 6.7 but somehow my supervisor keep telling me version 7 some is out there.
Can someone give me the confirmation?
Welcome to the Community,
VMware is the name of the Company, not of a specific product.
Anyway, from the version numbers you mentioned, I assume you are asking for vSphere (vCenter Server, and ESXi) for which the latest available version is 6.7.
There are however other products available which are version 7.x.
