==== Bug fixes

* Previously, during node reboots, especially during update operations, the node that interacted with the rebooting machine entered a `Ready=Unknown` state. This caused the Control Plane Machine Set Operator to enter an `UnavailableReplicas` condition and an `Available=false` state, which triggered alerts that demanded urgent action. However, manual intervention was not necessary because the condition was resolved when the node rebooted. With this release, a grace period for node unreadiness is provided. If a node enters an unready state, the Control Plane Machine Set Operator does not instantly enter an `UnavailableReplicas` condition or an `Available=false` state. (link:https://issues.redhat.com/browse/OCPBUGS-48325[*OCPBUGS-48325*]).
