- A new score extension for NodeResourcesFit plugin that merges the functionality of `NodeResourcesLeastAllocated`, `NodeResourcesMostAllocated`, `RequestedToCapacityRatio` plugins, which are marked as deprecated as of v1beta2. In v1beta1, the three plugins can still be used in v1beta1 but not at the same time with the score extension of `NodeResourcesFit`.

  Changed `kubectl create secret --help` description. There will be a short introduction to the three secret types and clearer guidance on how to use the command. ([#117930](https://github.com/kubernetes/kubernetes/pull/117930), [@LronDC](https://github.com/LronDC))

  // value automatically if one of them is empty and the other is non-empty.
  // When namespace is specified in dataSourceRef,
  // dataSource isn't set to the same value and must be empty.
  // There are three important differences between dataSource and dataSourceRef:
  // * While dataSource only allows two specific types of objects, dataSourceRef
  //   allows any non-core object, as well as PersistentVolumeClaim objects.

- Kubeadm: the deprecated kube-dns is no longer supported as an option. If "ClusterConfiguration.dns.type" is set to "kube-dns" kubeadm will now throw an error. ([#99646](https://github.com/kubernetes/kubernetes/pull/99646), [@rajansandeep](https://github.com/rajansandeep)) [SIG Cluster Lifecycle]

### SIG AWS

In v1.13 we worked on tighter integrations of Kubernetes API objects with AWS services. These include three out-of-tree alpha feature releases:

1) Alpha for AWS ALB (Application Load Balancer) integration to Kubernetes Ingress resources.
2) Alpha for CSI specification 0.3 integration to AWS EBS (Elastic Block Store)

- kubeadm: Added better handling of errors during unmount when calling `kubeadm reset`. When failing to unmount directories under `/var/run/kubelet`, kubeadm will now throw an error instead of showing a warning and continuing to clean up said directory. In such situations, it is better for you to inspect the problem and resolve it manually. Then, you can call `kubeadm reset` again to complete the cleanup.

`Initializers` admission plugin is enabled.([#51436](https://github.com/kubernetes/kubernetes/pull/51436))

* [Action required] The validation rule for metadata.initializers.pending[x].name is tightened. The initializer name must contain at least three segments, separated by dots. You can create objects with pending initializers and not rely on the API server to add pending initializers according to `initializerConfiguration`. If you do so, update the initializer name in the existing objects and...

  * Added support for printing in all supported `--output` formats to `kubectl create ...` and `kubectl apply ...` ([#38112](https://github.com/kubernetes/kubernetes/pull/38112), [@juanvallejo](https://github.com/juanvallejo))
  * Add three more columns to `kubectl get deploy -o wide` output. ([#39240](https://github.com/kubernetes/kubernetes/pull/39240), [@xingzhou](https://github.com/xingzhou))

- Kubeadm: added `show-join-command` as a new separate phase at the end of `kubeadm init`. You can skip printing the join information by using `kubeadm init --skip-phases=show-join-command`. Executing only this phase on demand will throw an error because the phase needs dependencies such as bootstrap tokens to be pre-populated.
