* Strategic Merge Patch

    * Reference docs now display the patch type and patch merge key used by `kubectl apply` to merge and identify unique elements in arrays.

## Changelog since v1.21.10

## Changes by Kind

### API Change

- Switch scheduler to generate the merge patch on pod status instead of the full pod ([#103133](https://github.com/kubernetes/kubernetes/pull/103133), [@marwanad](https://github.com/marwanad)) [SIG Scheduling]

    - A new option cloudConfigType has been added to the cloud-config file. Supported values are: `file`, `secret` and `merge` (`merge` is the default value).
    - To allow Azure cloud provider to read secrets, the [RBAC rules](https://github.com/kubernetes/kubernetes/pull/78242) should be configured.

#### CLI

- resource.k8s.io/ResourceClaim (alpha API): The strategic merge patch strategy for the `status.reservedFor` array was changed so that a strategic-merge-patch can now add individual entries. This change may break clients using strategic merge patch to update status, which rely on the previous behavior (replacing the entire array).

### Source Code

- Fixes a regression in v1beta1 PodDisruptionBudget handling of `strategic merge patch`-type API requests for the `selector` field. Prior to 1.21, these requests would merge `matchLabels` content and replace `matchExpressions` content. In 1.21, patch requests touching the `selector` field started replacing the entire selector. This is consistent with server-side apply and...

  joining `etcd` members is now enabled by default. ([#120228](https://github.com/kubernetes/kubernetes/pull/120228), [@pacoxu](https://github.com/pacoxu))

  kind.

#### Behavioral Changes

 - For all kinds in the API group version, a spec.selector default value is no longer
 available, because it's incompatible with `kubectl
 apply` and strategic merge patch. You must explicitly set the spec.selector value
 in your manifest. An object with a spec.selector value that does not match the labels in
 its spec.template is invalid.
