ConfigMap rendering [issue](https://github.com/kubernetes/kubernetes/issues/112081) was found in the 1.25.0 release. When ConfigMaps get updated within the API, they do not get rendered to the resulting pod's filesystem by the Kubelet. The feature has been [reverted to alpha](https://github.com/kubernetes/kubernetes/pull/112078) in the 1.25.1 release.
