- kube-apiserver: `--service-account-max-token-expiration` can now be used in combination with an external token signer `--service-account-signing-endpoint`, as long as the `--service-account-max-token-expiration` is not longer than the external token signer's max expiration. ([#129816](https://github.com/kubernetes/kubernetes/pull/129816), [@sambdavidson](https://github.com/sambdavidson)) [SIG...

  * All communication is now over TLS
  * Authorization plugins can be installed by kubeadm, including the new default of RBAC
  * The bootstrap token system now allows token management and expiration
* The [`kubefed` federation bootstrap tool](https://kubernetes.io/docs/tutorials/federation/set-up-cluster-federation-kubefed/) has also graduated to beta.

`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 not referenced from pods. This...

  is now available as alpha (off by default). When enabled, the `legacy-service-account-token-cleaner`
  controller loop removes service account token secrets that 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

unprivileged pods, using the proxy to perform privileged storage operations on the node.

Another feature moving to GA in v1.22 is CSI Service Account Token support. This feature allows CSI drivers to use pods' [bound service account tokens](https://kubernetes.io/docs/reference/access-authn-authz/service-accounts-admin/#bound-service-account-token-volume) instead of a more privileged identity. It also provides control over to re-publishing these volumes, so that short-lived tokens can be refreshed....
