- A `create` or `update` API request with duplicate items in a keyed list no longer wipes out managedFields. Examples include env var entries with the same name, or port entries with the same containerPort in a pod spec.

- CustomResourceDefinition schemas that use `x-kubernetes-list-map-keys` to specify properties that uniquely identify list items must make those properties required or have a default value, to ensure those properties are present for all list items. See https://kubernetes.io/docs/reference/using-api/api-concepts/#merge-strategy for details. ([#88076](https://github.com/kubernetes/kubernetes/pull/88076), [@eloyekunle](https://github.com/eloyekunle))...

- CRDs can have fields named `type` with value `array` and nested array with `items` fields without validation to fall over this. ([#85223](https://github.com/kubernetes/kubernetes/pull/85223), [@sttts](https://github.com/sttts))

* `kubectl get` will by default fetch large lists of resources in chunks of up to 500 items rather than requesting all resources up front from the server. This reduces the perceived latency of managing large clusters since the server returns the first set of results to the client much more quickly.  A new flag `--chunk-size=SIZE` may be used to alter the number of items or disable this feature when `0` is passed.  This is a beta feature. ([#53768](https://github.com/kubernet...

    * remainingItemCount is the number of subsequent items in the list which are not included in this list response. If the list request contained label or field selectors, then the number of remaining items is unknown and the field will be left unset and omitted during serialization. If the list is complete (either because it is not chunking or because this is the last chunk), then there are no more remaining items and this field will be left unset and omitted during serialization....

### SIG CLI

* **[beta]** Added support for mount options in persistent volumes.
* **[alpha]** All in one volume proposal - a new volume driver capable of projecting secrets, configmaps, and downward API items into the same directory.

## Deprecations
* Remove extensions/v1beta1 Jobs resource, and job/v1beta1 generator. ([#38614](https://github.com/kubernetes/kubernetes/pull/38614), [@soltysh](https://github.com/soltysh))

- Fixes a bug where `MutatingAdmissionPolicy` would fail to apply to objects with duplicate list items (like env vars). ([#135560](https://github.com/kubernetes/kubernetes/pull/135560), [@lalitc375](https://github.com/lalitc375) [SIG API Machinery]

- The new flag `--chunk-size=SIZE` has been added to `kubectl describe`. This flag may be used to alter the number of items or disable this feature when `0` is passed. ([#101171](https://github.com/kubernetes/kubernetes/pull/101171),...
