* kube-apiserver --advertise-address is now set using downward API for self-hosted Kubernetes with kubeadm. ([#56084](https://github.com/kubernetes/kubernetes/pull/56084), [@andrewsykim](https://github.com/andrewsykim))

*   kubectl `top node` now sorts by name and `top pod` sorts by namespace. Fixed a bug where results were inconsistently sorted. ([#53560](https://github.com/kubernetes/kubernetes/pull/53560),[ @dixudx](https://github.com/dixudx))

  restrictions that already apply to CustomResourceDefinition.
  If rule evaluation uses more compute than the limit, the API server aborts the evaluation and the
  admission check that was being performed is aborted; the `failurePolicy` for the ValidatingAdmissionPolicy
  determines the outcome. ([#115747](https://github.com/kubernetes/kubernetes/pull/115747), [@cici37](https://github.com/cici37))

- One new field "InternalTrafficPolicy" in Service is added.
  It specifies if the cluster internal traffic should be routed to all endpoints or node-local endpoints only.
  "Cluster" routes internal traffic to a Service to all endpoints.
  "Local" routes traffic to node-local endpoints only, and traffic is dropped if no node-local endpoints are ready.

### Cluster Lifecycle

## What’s New (Major Themes)

* Self hosted is no longer supported in the standard workflow. The feature flags have been removed and your self hosted cluster is no longer able to upgrade via kubeadm. ([#69878](https://github.com/kubernetes/kubernetes/pull/69878), [@Klaven](https://github.com/Klaven))

- If the user specifies an invalid timeout in the request URL, the request will be aborted with an HTTP 400.

- **Network**
  - [stable] Services can reference another service by DNS name, rather than being hosted in pods ([kubernetes/features#33](https://github.com/kubernetes/enhancements/issues/33))
