Welcome to vSphere-land!

Configuration Maximum changes from vSphere 6.0 to vSphere 6.5

vSphere 6.5 is now available and with every release VMware makes changes to the configuration maximums for vSphere. Since VMware never highlights what has changed between releases in their official Configuration Maximum 6.5 documentation, I thought I would compare the document with the 6.0 version and list the changes between the versions here.
