    Bug Fix(es):

    * The redhat-release-virtualization-host package no longer requires vdsm-hooks. In this release, the     installation of vdsm-hooks is not mandatory for the Red Hat Virtualization Host. (BZ#1976095)

    * Previously, rhsmcertd was not enabled by default on the Red Hat Virtualization Host. As a result, the     systems did not regularly report to RHSM while the subscription-manager reported no obvious issues and     repositories were properly enabled.
    In this release, rhsmcertd is enabled by default in RHVH, and as a result, RHSM now receives reports     regularly. (BZ#1958145)

    * In this release, the Red Hat Virtualization Host has been rebased on top of the RHEL 8.4.0 Batch #1     update. For more information, see the RHEL release notes. (BZ#1957242)

    * Red Hat Virtualization Host now includes an updated scap-security-guide-rhv which allows you to apply a     PCI DSS security profile to the system during installation, (BZ#1883793)
