- Kubectl: `kubectl get` will omit managed fields by default now. Users could set `--show-managed-fields` to true to show managedFields when the output format is either `json` or `yaml`.

- 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.

        arbitrary code execution. It is recommended to use JSON serialization
        instead of YAML, or, a better alternative, serialize to H5.

	1. In Namespaces that previously had the "DefaultDeny" annotation,
	   you can create equivalent v1 semantics by creating a
	   NetworkPolicy that matches all pods but does not allow any
	   traffic:

	   ```yaml
           kind: NetworkPolicy
           apiVersion: networking.k8s.io/v1
           metadata:
             name: default-deny
           spec:
             podSelector:
	   ```
