 ### `k8sattr.labelsAnnotationsSingular.allow`
 
-The `k8sattr.labelsAnnotationsSingular.allow` feature gate, when enabled, changes the default resource attribute key format from `k8s.<workload>.labels.<label-key>` to `k8s.<workload>.label.<label-key>` and `k8s.<workload>.annotations.<annotation-key>` to `k8s.<workload>.annotation.<annotation-key>`.
+The `k8sattr.labelsAnnotationsSingular.allow` feature gate is currently at beta stage and enabled by default. When enabled, it changes the default resource attribute key format from `k8s.<workload>.labels.<label-key>` to `k8s.<workload>.label.<label-key>` and `k8s.<workload>.annotations.<annotation-key>` to `k8s.<workload>.annotation.<annotation-key>`.
