### Immutable Secrets and ConfigMaps

Immutable Secrets and ConfigMaps graduates to GA. This feature allows users to specify that the contents of a particular Secret or ConfigMap is immutable for its object lifetime. For such instances, Kubelet will not watch/poll for changes and therefore reducing apiserver load.

- Promote Immutable Secrets/ConfigMaps feature to Beta and enable the feature by default.
  This allows to set `Immutable` field in Secrets or ConfigMap object to mark their contents as immutable. ([#89594](https://github.com/kubernetes/kubernetes/pull/89594), [@wojtek-t](https://github.com/wojtek-t)) [SIG Apps and Testing]
