- The CustomResourcePublishOpenAPI feature is now beta and enabled by default. CustomResourceDefinitions with [structural schemas](https://github.com/kubernetes/enhancements/blob/master/keps/sig-api-machinery/20190425-structural-openapi.md) now publish schemas in the OpenAPI document served at `/openapi/v2`. CustomResourceDefinitions with non-structural schemas have a `NonStructuralSchema` condition added with details about what needs to be corrected in the validation schema. ([#77825](https://...

  `Why not?' said the March Hare.

  Alice was silent.

- OpenAPI V2 will no longer publish aggregated apiserver OpenAPI for group-versions not matching the APIService specified group version ([#123624](https://github.com/kubernetes/kubernetes/pull/123624), [@Jefftree](https://github.com/Jefftree)) [SIG API Machinery and Testing]

- **Node**
  - [alpha] Publish node performance dashboard at http://node-perf-dash.k8s.io/#/builds ([docs](https://github.com/kubernetes/contrib/blob/master/node-perf-dash/README.md)) ([kubernetes/features#83](https://github.com/kubernetes/enhancements/issues/83))

- The pod phase lifecycle guarantees that terminal Pods, those whose states are Unready or Succeeded, can not regress and will have all container stopped. Hence, terminal Pods will never be reachable and should not publish their IP addresses on the Endpoints or EndpointSlices, independently of the Service TolerateUnready option.

- Kubelets configured to rotate client certificates now publish a `certificate_manager_server_ttl_seconds` gauge metric indicating the remaining seconds until certificate expiration.

- Changed kubectl `--subresource` flag to beta ([#116595](https://github.com/kubernetes/kubernetes/pull/116595), [@MadhavJivrajani](https://github.com/MadhavJivrajani))
- Changed metrics for aggregated discovery to publish new time series (alpha). ([#115630](https://github.com/kubernetes/kubernetes/pull/115630), [@Jefftree](https://github.com/Jefftree)) [SIG API Machinery and Testing]

- This change adds a new alpha feature Node Declared Features, which includes:
  - A new `Node.Status.DeclaredFeatures` field for Kubelet to publish node-specific features.
  - A library in `component-helpers` for feature registration and inference.
  - A scheduler plugin (`NodeDeclaredFeatures`) scheduler plugin to match pods with nodes that provide their required features.

- OpenAPI V2 will no longer publish aggregated API server OpenAPI for group versions that do not match the APIService specified group version. ([#123570](https://github.com/kubernetes/kubernetes/pull/123570), [@Jefftree](https://github.com/Jefftree))
