Citrix Provisioning

Cumulative Update 4 (CU4)

Release date: May 08, 2026

What’s new

Support for the New Microsoft SecureBoot CA Certificates

As documented by Microsoft at Windows Secure Boot certificate expiration and CA updates - Microsoft Support, the current certificates used for validating binaries when using Secure Boot are expiring in 2026 and have been replaced by new CA certificates which will be used in the future to validate that binaries are properly signed. This release of Citrix Provisioning includes support for secure boot when these new certificates are being used. See Windows Secure Boot certificate expiration and CA updates for details on how you can prepare for supporting secure boot once this has happened.

It is vital that you start the process of upgrading the hypervisor and existing VMs as well as upgrading to a version of Citrix Provisioning that supports the new certificates now to avoid outages starting in June 2026.

For more information, see Windows Secure Boot certificate expiration and CA updates.
