### Container Images

All container images are available as manifest lists and support the described
architectures. It is also possible to pull a specific architecture directly by
adding the "-$ARCH" suffix  to the container image name.

- Fixed missing validation of uniqueness of list items in lists with `x-kubernetes-list-type: map` or `x-kubernetes-list-type: set` in CustomResources. ([#84920](https://github.com/kubernetes/kubernetes/pull/84920), [@sttts](https://github.com/sttts)) [SIG API Machinery]

* [Alpha] The Kubernetes API server now supports the ability to break large LIST calls into multiple smaller chunks. A client can specify a limit to the number of results to return. If more results exist, a token is returned that allows the client to continue the previous list call repeatedly until all results are retrieved.  The resulting list is identical to a list call that does not perform chunking, thanks to capabilities provided by etcd3.  This allows the server to...

* Added a `kubeadm config images list` command that lists required container images for a kubeadm install. ([#63450](https://github.com/kubernetes/kubernetes/pull/63450), [@chuckha](https://github.com/chuckha))

- Updates `kubectl kustomize` and `kubectl apply -k` to Kustomize v4.5.4 ([#108994](https://github.com/kubernetes/kubernetes/pull/108994), [@KnVerey](https://github.com/KnVerey))
- When invoked with `-list-images`, the `e2e.test` binary now also lists the images that might be needed for storage tests. ([#108458](https://github.com/kubernetes/kubernetes/pull/108458), [@pohly](https://github.com/pohly))

### Bug or Regression

- Fix list cost estimation in Priority and Fairness for list requests with metadata.name specified. ([#112557](https://github.com/kubernetes/kubernetes/pull/112557), [@marseel](https://github.com/marseel)) [SIG API Machinery]

### Bug or Regression

- Kube-apiserver: gzip compression switched from level 4 to level 1 to improve large list call latencies in exchange for higher network bandwidth usage (10-50% higher). This increases the headroom before very large unpaged list calls exceed request timeout limits.
