- 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))

- CRDs: For structural schemas, non-nullable null map fields will now be dropped and defaulted if a default is available. null items in the list will continue being preserved, and fail validation if not nullable. ([#95423](https://github.com/kubernetes/kubernetes/pull/95423), [@apelisse](https://github.com/apelisse)) [SIG API Machinery]

- Fixed a bug in the API server where empty collections of ValidatingAdmissionPolicies did not have an `items` field. ([#124568](https://github.com/kubernetes/kubernetes/pull/124568), [@xyz-li](https://github.com/xyz-li)) [SIG API Machinery]

- Fixed a rare race condition handling requests that timeout. ([#107452](https://github.com/kubernetes/kubernetes/pull/107452), [@liggitt](https://github.com/liggitt))
- Fixed a regression in 1.23 that incorrectly pruned data from array items of a custom resource that set `x-kubernetes-preserve-unknown-fields: true`. ([#107688](https://github.com/kubernetes/kubernetes/pull/107688), [@liggitt](https://github.com/liggitt))

The initial capacity does not bound its size:
maps grow to accommodate the number of items
stored in them, with the exception of <code>nil</code> maps.
A <code>nil</code> map is equivalent to an empty map except that no elements
may be added.
