Am I crazy or didn't I see that the vSphere APIs for Data Protection were going to be included in the free edition of the vSphere 6 Hypervisor? I thought I saw that in the announcement, but can't find any documentation now that I'm looking for it.
This document, VMware vSphere Storage APIs for Third Party Integration
now says "The vSphere Storage APIs - Data Protection is included with all vSphere editions and kits." Not sure if the vSphere Hypervisor is counted as an "edition."
