VMware vSphere 6.5 Update 1 has been released on July 27, 2017 with several bug fix, some improvements, but also some interesting changing in maximum numbers (for vCenter in linked-mode) and an interesting news for the Foundation edition that now can manage up to 4 nodes (and not only 3 nodes like in the past).
Seems a minor improvement, but demostrare how VMware takes care of its customers. In discussions with customers with smaller environments, VMware has received feedback that 3 host environments were too small in many cases, and just another hosts could be enough (of course still for SMB enviroments). This is why with vSphere 6.5 Update 1 VMware is now increasing the number of hosts that vCenter Server Foundation will support from 3 host to 4.
