- 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))

### Apps

* **[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))

- 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),...

- Fixes a regression in 1.23 that incorrectly pruned data from array items of a custom resource that set `x-kubernetes-preserve-unknown-fields: true` ([#107689](https://github.com/kubernetes/kubernetes/pull/107689), [@liggitt](https://github.com/liggitt)) [SIG API Machinery]

## Dependencies

* Fix incorrectly propagated ResourceVersion in ListRequests returning 0 items. ([#64150](https://github.com/kubernetes/kubernetes/pull/64150), [@wojtek-t](https://github.com/wojtek-t))

- The Kubernetes API server now correctly detects and closes existing TLS connections when its client...

- Bookmark events are now sent immediately after all items in the watchCache store have been processed, improving consistency in client behavior. ([#127012](https://github.com/kubernetes/kubernetes/pull/127012), [@Chaunceyctx](https://github.com/Chaunceyctx))
