- Pods owned by a Job now uses the labels `batch.kubernetes.io/job-name` and `batch.kubernetes.io/controller-uid`.
  The legacy labels `job-name` and `controller-uid` are still added for compatibility. ([#114930](https://github.com/kubernetes/kubernetes/pull/114930), [@kannon92](https://github.com/kannon92))

- Kubelet.exe on Windows now checks that the process running as administrator and the executing user account is listed in the built-in administrators group.  This is the equivalent to checking the process is running as uid 0.

* The options passed to a flexvolume plugin's mount command now contains the pod name (`kubernetes.io/pod.name`), namespace (`kubernetes.io/pod.namespace`), uid (`kubernetes.io/pod.uid`), and service account name (`kubernetes.io/serviceAccount.name`). ([#39488](https://github.com/kubernetes/kubernetes/pull/39488), [@liggitt](https://github.com/liggitt))

- Fixed an issue where the API server did not send impersonated UID to authentication webhooks. ([#116681](https://github.com/kubernetes/kubernetes/pull/116681), [@stlaz](https://github.com/stlaz)) [SIG API Machinery and Auth]

- Client-go impersonation config can specify a UID to pass impersonated uid information through in requests. ([#104483](https://github.com/kubernetes/kubernetes/pull/104483), [@margocrawf](https://github.com/margocrawf))

- Kube API server accepts `Impersonate-Uid` header to impersonate a user with a specific UID, in the same way that you can currently use `Impersonate-User`, `Impersonate-Group` and `Impersonate-Extra`. ([#99961](https://github.com/kubernetes/kubernetes/pull/99961), [@margocrawf](https://github.com/margocrawf))

- Fixed a bug where unwanted fields were being returned from a `create --dry-run`: uid and, if generateName was used, name. ([#107088](https://github.com/kubernetes/kubernetes/pull/107088), [@joejulian](https://github.com/joejulian))

- Fixes a regression in the pod binding subresource to honor the `metadata.uid` precondition.

  - `alpha` support (guarded by the `ServiceAccountTokenPodNodeInfo` feature gate) for including the node name (and uid, if the node exists) as additional claims in service account tokens it issues which are bound to pods, and `authentication.kubernetes.io/node-name` and `authentication.kubernetes.io/node-uid` extra user info when the token is used to authenticate.
