* Fixes a regression proxying responses from aggregated API servers which could cause watch requests to hang until the first event was received ([#75887](https://github.com/kubernetes/kubernetes/pull/75887), [@liggitt](https://github.com/liggitt))

- Improved how the API server responds to **list** requests where the response format negotiates to Protobuf. List responses in Protobuf are marshalled one element at the time, drastically reducing memory needed to serve large collections. Streaming list responses can be disabled via the `StreamingCollectionEncodingToProtobuf` feature gate. ([#129407](https://github.com/kubernetes/kubernetes/pull/129407),...

  - `response.patch` and `response.patchType` are not permitted from validating admission webhooks
  - `apiVersion: "admission.k8s.io/v1"` is required
  - `kind: "AdmissionReview"` is required
  - `response.uid: "<value of request.uid>"` is required

- Kube-apiserver: redirect responses are no longer returned from backends by default. Set `--aggregator-reject-forwarding-redirect=false` to continue forwarding redirect responses. ([#112193](https://github.com/kubernetes/kubernetes/pull/112193), [@jindijamie](https://github.com/jindijamie)) [SIG API Machinery and Testing]

- kubeadm: added "disable success" and "disable denial" as parameters of the "cache" plugin in the Corefile managed by kubeadm. This is to prevent conflicting responses during CoreDNS cache updates.

* Resolves an issue serving aggregated APIs backed by services that respond to requests to `/` with non-2xx HTTP responses ([#79895](https://github.com/kubernetes/kubernetes/pull/79895), [@deads2k](https://github.com/deads2k))

- Fixed a bug that was blocking extensible error handling when serializing API responses error out. Previously, serialization failures always resulted in the status code of the original response being returned. Now, the following behavior occurs: ([#67041](https://github.com/kubernetes/kubernetes/pull/67041), [@tristanburgess](https://github.com/tristanburgess))
