+=== New features and enhancements
+
+* This release of the {descheduler-operator} adds a new Technology Preview descheduler profile called `DevKubeVirtRelieveAndMigrate`. This profile is only available for use with {VirtProductName}.
+// +
+// For more information, see xref:../../../virt/managing_vms/advanced_vm_management/virt-enabling-descheduler-evictions.adoc#virt-enabling-descheduler-evictions[Enabling descheduler evictions on virtual machines].

+[id="descheduler-operator-5.1.2-bug-fixes"]
+=== Bug fixes
+
+* Previously, when the `LifecycleAndUtilization` profile was enabled, pods from protected namespaces ([x-]`openshift-*`, `kube-system`, `hypershift`) could be evicted. Pods in these namespaces should never be evicted. With this release, these protected namespaces are now properly excluded from eviction when the `LifecycleAndUtilization` profile is enabled.
