About Software Updates and Upgrades

XenCenter issues notifications about available Citrix Hypervisor and XenCenter updates and upgrades on the Updates tab in the Notifications view.

XenCenter is configured by default to automatically check for new Citrix Hypervisor and XenCenter updates and upgrades at regular intervals, and you will be notified when a new update or product version is available. It is recommended that you install all published updates. You can check for available updates manually at any time and verify that you are running the latest version of both Citrix Hypervisor and XenCenter. To do this, select Notifications > Updates and then click Refresh.
