- `kube-controller-manager`: The `LegacyServiceAccountTokenCleanUp` feature gate is now `beta` and enabled by default. When enabled, legacy auto-generated service account token secrets are auto-labeled with a `kubernetes.io/legacy-token-invalid-since` label if the credentials have not been used in the time specified by `--legacy-service-account-token-clean-up-period` (defaulting to one year), **and** are referenced from the `.secrets` list of a ServiceAccount object, **and**  are...

- Kubeadm: during "upgrade apply/diff/node", in case the `ClusterConfiguration.imageRepository` stored in the "kubeadm-config" `ConfigMap` contains the legacy "k8s.gcr.io" repository, modify it to the new default "registry.k8s.io". Reflect the change in the in-cluster `ConfigMap` only during "upgrade apply". ([#110343](https://github.com/kubernetes/kubernetes/pull/110343), [@neolit123](https://github.com/neolit123))...

- 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))

- `kube-controller-manager`: The `LegacyServiceAccountTokenCleanUp` feature gate
  is now available as alpha (off by default). When enabled, the `legacy-service-account-token-cleaner`
