Why does using vDisk Versions help manage the image release process?

vDisk versions manage different states of an existing OS image rather than automatically upgrading virtual desktops to an entirely new operating system version.

vDisk Versions, a feature of Citrix Provisioning Services (PVS), enables administrators to create and manage multiple read-only versions of a single master vDisk, along with an associated writable base. This provides centralized, automated management of the image release process and the critical ability to quickly revert to a previous stable version if an update introduces issues, minimizing downtime.

Compatibility with the Microsoft VHD specification describes the vDisk format, not the specific benefit of 'vDisk Versions' for managing the image release process.

While deploying drivers and patches is part of image management, 'vDisk Versions' specifically adds the benefit of managing different *states* and the ability to *rollback*, which is a key advantage missing from this description.
