## Changelog since v1.3.0-beta.2

### Action Required

* [kubelet] Allow opting out of automatic cloud provider detection in kubelet. By default kubelet will auto-detect cloud providers ([#28258](https://github.com/kubernetes/kubernetes/pull/28258), [@vishh](https://github.com/vishh))

- kubelet: Users can now enable the alpha NodeLease feature gate to have the Kubelet create and periodically renew a Lease in the kube-node-lease namespace. The lease duration defaults to 40s, and can be configured via the kubelet.config.k8s.io/v1beta1.KubeletConfiguration's NodeLeaseDurationSeconds field. ([#66257](https://github.com/kubernetes/kubernetes/pull/66257),...

* action required: Deprecate the kubelet's cadvisor port. The default will change to 0 (disabled) in 1.12, and the cadvisor port will be removed entirely in 1.13. ([#59827](https://github.com/kubernetes/kubernetes/pull/59827), [@dashpole](https://github.com/dashpole))

* [alpha] Rotation of the server TLS certificate on the kubelet. See [TLS bootstrapping - approval controller](https://kubernetes.io/docs/admin/kubelet-tls-bootstrapping/#approval-controller).

* [alpha] Rotation of the client TLS certificate on the kubelet. See [TLS bootstrapping - kubelet configuration](https://kubernetes.io/docs/admin/kubelet-tls-bootstrapping/#kubelet-configuration).

### Other notable changes

* fix kubelet fail to delete orphaned pod directory when the kubelet's pods directory (default is "/var/lib/kubelet/pods") symbolically links to another disk device's directory ([#79094](https://github.com/kubernetes/kubernetes/pull/79094), [@gaorong](https://github.com/gaorong))

- Revised the Kubelet API Authorization with new subresources, that allow finer-grained authorization checks and access control for kubelet endpoints.
  Provided you enable the `KubeletFineGrainedAuthz` feature gate, you can access kubelet's `/healthz` endpoint by granting the caller `nodes/helathz` permission in RBAC.
