# v1.8.9

[image credential providers](https://kubernetes.io/docs/tasks/kubelet-credential-provider/kubelet-credential-provider/)
has now graduated to Beta.
This allows the kubelet to dynamically retrieve credentials for a container image registry
using exec plugins, rather than storing credentials on the node's filesystem.

### Contextual Logging in Alpha

- The JWT authenticator configuration set via the `--authentication-config` flag is now dynamically reloaded as the file changes on disk. ([#123525](https://github.com/kubernetes/kubernetes/pull/123525), [@enj](https://github.com/enj))

- Added a new `ServiceCIDR` type that allows to dynamically configure the cluster range used to allocate `Service ClusterIPs` addresses. ([#116516](https://github.com/kubernetes/kubernetes/pull/116516), [@aojea](https://github.com/aojea))
