- Add node_authorizer_actions_duration_seconds metric that can be used to estimate load to node authorizer. ([#92466](https://github.com/kubernetes/kubernetes/pull/92466), [@mborsz](https://github.com/mborsz)) [SIG API Machinery, Auth and Instrumentation]

- LimitRange and Endpoints resources can be created via an update API call if the object does not already exist. When this occurs, an authorization check is now made to ensure the user making the API call is authorized to create the object. In previous releases, only an update authorization check was performed.

  - kube-apiserver v1.25.0 - v1.25.3
  - kube-apiserver v1.24.0 - v1.24.7
