* [alpha] Integration with [containerd] (https://github.com/containerd/containerd) , which supports basic pod lifecycle and image management. ([docs](https://github.com/kubernetes-incubator/cri-containerd/blob/master/README.md) and [release notes](https://github.com/kubernetes-incubator/cri-containerd/releases/tag/v0.1.0)) ([kubernetes/features#286](h...

- Added new optional APIs in `ResouceSlice.Basic` and `ResourceClaim.Status.AllocatedDeviceStatus`. ([#130160](https://github.com/kubernetes/kubernetes/pull/130160), [@KobayashiD27](https://github.com/KobayashiD27)) [SIG API Machinery, Apps, Architecture, Node, Release, Scheduling and Testing]

- Certain `requestBody` parameters in the OpenAPI `v3` are now correctly marked as required. ([#120735](https://github.com/kubernetes/kubernetes/pull/120735), [@Jefftree](https://github.com/Jefftree))
- Changed `kubectl help` to display basic details for subcommands from plugins. ([#116752](https://github.com/kubernetes/kubernetes/pull/116752), [@xvzf](https://github.com/xvzf))

### Other (Cleanup or Flake)

- Added basic Denial Of Service prevention for the the node-local kubelet `podresource` API ([#116459](https://github.com/kubernetes/kubernetes/pull/116459), [@ffromani](https://github.com/ffromani)) [SIG Node and Testing]

  - the `--make-symlinks` flag, deprecated in v1.14, has been removed. ([#80017](https://github.com/kubernetes/kubernetes/pull/80017), [@Pothulapati](https://github.com/Pothulapati))

- kube-apiserver

- The conformance tests:
  - Services should serve multiport endpoints from pods
  - Services should serve a basic endpoint from pods
  were only validating the API objects, not performing any validation on the actual Services implementation.
