yum update --enablerepo=xcp-ng-testing,xcp-ng-candidates
reboot # not mandatory but recommended for testing
The usual update rules apply: pool coordinator first, etc.
What to test
As usual, normal use and anything else you want to test.
Additionally, a cold boot (shutdown and start) of the UEFI VMs would also help testing the edk2 fix.

We would like to thank users who shared feedback since our last call for testing: @acebmxer, @jr-m4, @bufanda, @flakpyro, @Andrew, @MajorP93, @JeffBerntsen, @manilx, @XCP-ng-JustGreat, @john205, @Greg_E.
We are aware of the frequency of these updates and strive to batch packages as much as possible. However, recent unplanned security updates require immediate attention. While drafting this message, we received another security update that we will release shortly.
