*   [beta] API chunking via the limit and continue request parameters is promoted to beta in this release. Client libraries using the Informer or ListWatch types will automatically opt in to chunking. ([#52949](https://github.com/kubernetes/kubernetes/pull/52949),[ @smarterclayton](https://github.com/smarterclayton))

- Fixed overriding default `KubeletConfig` fields in drop-in configs if not set. ([#121193](https://github.com/kubernetes/kubernetes/pull/121193), [@sohankunkerkar](https://github.com/sohankunkerkar))
- Graduated API List chunking (aka pagination) feature to `stable`. ([#119503](https://github.com/kubernetes/kubernetes/pull/119503), [@wojtek-t](https://github.com/wojtek-t))

- Added `WatchListClient` feature gate to `client-go`. When enabled, it allows the client to receive a stream of individual items instead of chunking from the server.

    * Added metrics aggregator_openapi_v2_regeneration_count, aggregator_openapi_v2_regeneration_gauge and apiextension_openapi_v2_regeneration_count metrics counting the triggering APIService and CRDs and the reason (add, update, delete).
* Fix an issue with toleration merging & whitelist checking in the PodTolerationRestriction admission controller. ([#81732](https://github.com/kubernetes/kubernetes/pull/81732), [@tallclair](https://github.com/tallclair))

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 use less memory and CPU when very large lists are returned. This feature is gated as APIListChunking and is not enabled by default. The 1.9 release will begin using this by de...

* Check for known manifests during preflight instead of only checking for non-empty manifests directory. This makes the preflight checks less heavy-handed by specifically checking for well-known files (kube-apiserver.yaml, kube-controller-manager.yaml, kube-scheduler.yaml, etcd.yaml) in /etc/kubernetes/manifests instead of simply checking for a non-empty directory.

- `ValidatingAdmissionPolicy` now provides a status field that contains results of type checking the validation expression.
  The type checking is fully informational, and the behavior of the policy is unchanged. ([#115668](https://github.com/kubernetes/kubernetes/pull/115668), [@jiahuif](https://github.com/jiahuif))

- Kubeadm: allow the "certs check-expiration" command to not require the existence of the cluster CA key (ca.key file) when checking the expiration of managed certificates in kubeconfig files.
