 ## Labels, annotations and taints used on API objects
 
+
+### apf.kubernetes.io/autoupdate-spec
+
+Type: Annotation
+
+Example: `apf.kubernetes.io/autoupdate-spec: "true"`
+
+Used on: [`FlowSchema` and `PriorityLevelConfiguration` Objects](/concepts/cluster-administration/flow-control/#defaults)
+
+If this annotation is set to true on a FlowSchema or PriorityLevelConfiguration, the `spec` for that object
+is managed by the kube-apiserver. If the API server does not recognize an APF object, and you annotate it
+for automatic update, the API server deletes the entire object. Otherwise, the API server does not manage the
+object spec.
+For more details, read  [Maintenance of the Mandatory and Suggested Configuration Objects](/docs/concepts/cluster-administration/flow-control/#maintenance-of-the-mandatory-and-suggested-configuration-objects).
