<p>
A field declared with a type but no explicit field name is called an <i>embedded field</i>.
An embedded field must be specified as
a type name <code>T</code> or as a pointer to a non-interface type name <code>*T</code>,
and <code>T</code> itself may not be
a pointer type or type parameter. The unqualified type name acts as the field name.

### CLI Improvements
- The kubectl's api-resource command now has a `--sort-by` flag to sort resources by name or kind. ([#81971](https://github.com/kubernetes/kubernetes/pull/81971), [@laddng](https://github.com/laddng))
- A new `--prefix` flag added into kubectl logs which prepends each log line with information about it's source (pod name and container name) ([#76471](https://github.com/kubernetes/kubernetes/pull/76471), [@m1kola](https://github.com/m1kola))

- Multiple Kubernetes clusters can now share the same resource group
    - When upgrading from previous releases, issues will arise with public IPs if multiple clusters share the same resource group. To solve these problems, make the following changes to the cluster:
Recreate the relevant LoadBalancer services, or add a new tag 'kubernetes-cluster-name: <cluster-name>' manually for existing public IPs.

### Failing Test

- Kubelet: the HostPort implementation in dockershim was not taking into consideration the HostIP field, causing that the same HostPort can not be used with different IP addresses.

- The `NamespaceDefaultLabelName` is promoted to GA in this release. All Namespace API objects have a `kubernetes.io/metadata.name` label matching their `metadata.name` field to allow selecting any `namespace` by its name using a label selector. ([#101342](https://github.com/kubernetes/kubernetes/pull/101342), [@rosenhouse](https://github.com/rosenhouse))

    * Notes on LB name:
    * to ensure backword and forward compat:
    * - SingleStack -v4 (pre v1.16) => BackendPool name == clusterName
    * - SingleStack -v6 => BackendPool name == clusterName (all cluster bootstrap uses this name)
    * DualStack:
    * => IPv4 BackendPool name == clusterName
    * => IPv6 BackendPool name == <clusterName>-IPv6
    * This result into:

- Specifying PluginConfig for the same plugin more than once fails scheduler startup.
  
  Specifying extenders and configuring .ignoredResources for the NodeResourcesFit plugin fails ([#88870](https://github.com/kubernetes/kubernetes/pull/88870), [@alculquicondor](https://github.com/alculquicondor)) [SIG Scheduling]

- Kubeadm: fixed a bug where the node registration information for a given node was not fetched correctly during "kubeadm upgrade node" and the node name can end up being incorrect in cases where the node name is not the same as the host name. ([#134363](https://github.com/kubernetes/kubernetes/pull/134363), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

* Ensure orphan public IPs on Azure deleted when service recreated with the same name. ([#70463](https://github.com/kubernetes/kubernetes/pull/70463), [@feiskyer](https://github.com/feiskyer))

- Kubeadm: fixed a bug where the node registration information for a given node was not fetched correctly during "kubeadm upgrade node" and the node name can end up being incorrect in cases where the node name is not the same as the host name.
