- `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.

/reference/access-authn-authz/rbac/#aggregated-clusterroles), introduced in 1.9, graduated to stable status with no changes in 1.11, and [client-go credential plugins](https://kubernetes.io/docs/reference/access-authn-authz/authentication/#client-go-credential-plugins)  graduated to beta status, while also adding support for obtaining TLS credentials from an external plugin.

Kubernetes 1.11 also makes it easier to see what's happening, as audit events can now be annotated with information...

### 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/).

- Promoted pod resource `limit/request` metrics to stable. ([#115454](https://github.com/kubernetes/kubernetes/pull/115454), [@dgrisonnet](https://github.com/dgrisonnet))
- Removed AWS kubelet credential provider. Please use the external kubelet credential provider binary named `ecr-credential-provider` instead. ([#116329](https://github.com/kubernetes/kubernetes/pull/116329), [@dims](https://github.com/dims)) [SIG Node, Storage and Testing]

- 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. ([#118596](https://github.com/kubernetes/kubernetes/pull/118596), [@SataQiu](https://github.com/SataQiu)) [SIG Node]

#### Credential provider

### Auth

* 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.

- Kubelet external Credential Provider feature is moved to GA. Credential Provider Plugin and Credential Provider Config APIs updated from `v1beta1` to `v1` with no API changes. ([#111616](https://github.com/kubernetes/kubernetes/pull/111616), [@ndixita](https://github.com/ndixita))
