This update fixes the following bugs among others:
* Previously, pre-flight installer validation for OpenShift Container
Platform on OpenStack was performed on the flavor metadata. This could
prevent installations to flavors detected as `baremetal`, which might have
the required capacity to complete the installation. This is usually caused
by OpenStack administrators not setting the appropriate metadata on their
bare metal flavors. Validations are now skipped on flavors detected as
`baremetal`, to prevent incorrect failures from being reported.
(BZ#1889416)
* Previously, there was a broken link on the OperatorHub install page of
the web console, which was intended to reference the cluster monitoring
documentation. This has been fixed. (BZ#1904600)
