### API Change

- Protobuf serialization of metav1.MicroTime timestamps (used in `Lease` and `Event` API objects) has been corrected to truncate to microsecond precision, to match the documented behavior and JSON/YAML serialization. Any existing persisted data is truncated to microsecond when read from etcd.

- kubeadm: added the feature gate `NodeLocalCRISocket`. When the feature gate is enabled, kubeadm will generate the `/var/lib/kubelet/instance-config.yaml` file to customize the `containerRuntimeEndpoint` field in the kubelet configuration for each node and will not write the same CRI socket on the Node object as an annotation.
