- Updated an audit annotation key used by the `…/serviceaccounts/<name>/token` resource handler.
  The annotation used to persist the issued credential identifier is now `authentication.kubernetes.io/issued-credential-id`. ([#123098](https://github.com/kubernetes/kubernetes/pull/123098), [@munnerz](https://github.com/munnerz)) [SIG Auth]

natively within Kubernetes, without exposing an HTTP endpoint or
using an extra executable.

### Kubelet Credential Provider Graduates to Beta

Originally released as Alpha in Kubernetes 1.20, the kubelet's support for
[image credential providers](https://kubernetes.io/docs/tasks/kubelet-credential-provider/kubelet-credential-provider/)
has now graduated to Beta.

### External credential providers

feature gate `DisableKubeletCloudCredentialProviders` which allows disabling the in-tree kubelet credential providers.
  
  The feature gate `DisableKubeletCloudCredentialProviders` is currently in Alpha, which means is currently disabled by default. Once this feature gate moves to beta, in-tree credential providers will be disabled by default, and users will need to migrate to use external credential providers.

- The AWS credential provider can now obtain ECR credentials even without the AWS cloud provider or being on an EC2 instance. Additionally, AWS credential provider caching has been improved to honor the ECR credential timeout.

  - `alpha` support (guarded by the `ServiceAccountTokenJTI` feature gate) for adding a `jti` (JWT ID) claim to service account tokens it issues, adding an `authentication.kubernetes.io/credential-id` audit annotation in audit logs when the tokens are issued, and `authentication.kubernetes.io/credential-id` entry in the extra user info when the token is used to authenticate.

### External credential provider for client-go

The client-go credential plugins can now be passed in the current cluster information via the `KUBERNETES_EXEC_INFO` environment variable. Learn more about this on [client-go credential plugins documentation](https://docs.k8s.io/reference/access-authn-authz/authentication/#client-go-credential-plugins/).

- Kubelet: The `--azure-container-registry-config` flag has been deprecated and will be removed in a future release, please use `--image-credential-provider-config` and `--image-credential-provider-bin-dir` to setup acr credential provider instead.
