 ==== Bug fixes
 
-* Previously, during node reboots, especially during update operations, the node that interacts with the rebooting machine entered a `Ready=Unknown` state for a short amount of time. This situation caused the Control Plane Machine Set Operator to enter an `UnavailableReplicas` condition and then an `Available=false` state. The `Available=false` state triggered alerts that demanded urgent action, but in this case, intervention was only required for a short period of time until the node rebooted. With this release, a grace period for node unreadiness is provided so 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*]).
