A question that’s often asked by existing customers relates to what exactly to the release numbers refer to? So here’s a quick and simple explanation on how Nutanix categorises their releases.
major . minor . patch . hot fix
So in the example of 18.104.22.168 you’ll observe the 5.9 is the main release (including additional updates/features), with 2 patches on that release with 4 additional hotfixes applied to that code level.
