* API fields that previously serialized null arrays as `null` and empty arrays as `[]` no longer distinguish between those values and always output `[]` when serializing to JSON. ([#43422](https://github.com/kubernetes/kubernetes/pull/43422), [@liggitt](https://github.com/liggitt))

- 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

- 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).
   ([#122276](https://github.com/kubernetes/kubernetes/pull/122276), [@pohly](https://github.com/pohly))

- Return error when the scoring plugin returns score out of range `[0, 100]`. ([#81015](https://github.com/kubernetes/kubernetes/pull/81015), [@draveness](https://github.com/draveness))
- Use a named array instead of a score array in normalizing-score phase. ([#80901](https://github.com/kubernetes/kubernetes/pull/80901), [@draveness](https://github.com/draveness))

- Dynamic Resource Allocation (DRA): in the `pod.spec.recourceClaims` array, the `source` indirection is no longer necessary. Instead of e.g. `source: resourceClaimTemplateName: my-template`, one can write `resourceClaimTemplateName: my-template`.

- Fix: delete non existing Azure disk issue ([#107406](https://github.com/kubernetes/kubernetes/pull/107406), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider]
- 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

Services which can use IPv4, IPv6, or both, and you can change this setting for existing Services. Details are available in updated [IPv4/IPv6 dual-stack docs](https://docs.k8s.io/concepts/services-networking/dual-stack/), which cover the nuanced array of options.

We expect this implementation to progress from alpha to beta and GA in coming releases, so we’re eager to have you comment about your dual-stack experiences in [#k8s-dual-stack](https://kubernetes.slack.com/messages/k8s-dual-stack)...

- Added support for specifying `controlplane` or `cluster` egress selectors in JWT authenticators via the `issuer.egressSelectorType` field in the `AuthenticationConfiguration.jwt` array. If unset, the previous behavior of using no egress selector is preserved. This functionality requires the `StructuredAuthenticationConfigurationEgressSelector` beta feature gate (enabled by default).
