implementation must:

<ul>
	<li>Represent integer constants with at least 256 bits.</li>

	<li>Represent floating-point constants, including the parts of
	    a complex constant, with a mantissa of at least 256 bits
	    and a signed binary exponent of at least 16 bits.</li>

	<li>Give an error if unable to represent an integer constant
	    precisely.</li>

* `kubectl cp` now supports completion.

added to score nodes by available storage capacity. It's in alpha and disabled by default. The `VolumeCapacityPriority` alpha feature was replaced with this, and the default behavior was changed. The `VolumeCapacityPriority` preferred a node with the least allocatable, but the `StorageCapacityScoring` preferred a node with the maximum allocatable. See [KEP-4049](https://github.com/kubernetes/enhancements/blob/master/keps/sig-storage/4049-storage-capacity-scoring-of-nodes-for-dynamic-provisioning/README.md)...

  
  VM Hardware version less than 15 is deprecated as of v1.21. Please consider upgrading the Node VM Hardware version to 15 or above. vSphere CSI Driver recommends Node VM's Hardware version set to at least vmx-15.
  

  Now, when unschedulable Pods are updated, the scheduling queue checks with QueueingHint(s) whether the update may make the pods schedulable, and requeues them to activeQ/backoffQ **only when** at least one QueueingHint(s) return Queue. 
  
  Action required for custom scheduler plugin developers:

updates to bypass a Validating Admission Webhook. You are only affected
by this vulnerability if you run a Validating Admission Webhook for Nodes
that denies admission based at least partially on the old state of the
Node object.

**Note**: This only impacts validating admission plugins that rely on old
values in certain fields, and does not impact calls from kubelet that go

- kubeadm: When certificates are present in joining a new control plane now ensures that they match at least the required SANs ([#73093](https://github.com/kubernetes/kubernetes/pull/73093), [@ereslibre](https://github.com/ereslibre))

`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...

- `kubectl exec` now allows using the resource name to select a matching pod and `--pod-running-timeout` flag to wait till at least one pod is running. ([#73664](https://github.com/kubernetes/kubernetes/pull/73664), [@prksu](https://github.com/prksu))
