- 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.

    *   Bug fixes in validation test suites.
*   [beta] [cri-containerd](https://github.com/kubernetes-incubator/cri-containerd): CRI implementation for containerd is now v1.0.0-beta.0, [[@Random-Liu](https://github.com/Random-Liu)]
    *   This release supports Kubernetes 1.9+ and containerd v1.0.0+.
    *   Pass all Kubernetes 1.9 e2e test, node e2e test and CRI validation tests.

  * Enhance CNI plugin compatibility, supports flannel, calico, weave and so on.
  * Pass all CRI validation conformance tests and node end-to-end conformance tests.
  * Add experimental Unikernel support.

- E2e.test and e2e_node.test: tests which depend on alpha or beta feature gates now have `Feature:Alpha` or `Feature:Beta` as Ginkgo labels. The inline text is `[Alpha]` or `[Beta]`, as before. ([#124350](https://github.com/kubernetes/kubernetes/pull/124350), [@pohly](ht...

### Feature

- Kubernetes is now built with Golang 1.16.9 (#105672, @cpanato) [SIG Cloud Provider, Instrumentation, Release and Testing]

### Failing Test

- Backport: e2e.test now uses the secure port to retrieve metrics data to ensure compatibility with 1.21 and 1.22 (for upgrade tests) (#104328, @pohly) [SIG API Machinery, Instrumentation, Storage and Testing]

### Bug or Regression

- Aggregate errors when putting vmss

- The `NetworkPolicyLegacy` test suite (deprecated in `v1.21`) has now officially been removed in favor of the new table driven e2e tests. ([#118915](https://github.com/kubernetes/kubernetes/pull/118915), [@astoycos](https://github.com/astoycos))

### Windows support improved

- [Performance dashboards](http://perf-dash.k8s.io/#/?jobname=soak-tests-capz-windows-2019) added support for Windows
- [Unit tests](https://github.com/kubernetes/kubernetes/issues/51540) added support for Windows
- [Conformance tests](https://github.com/kubernetes/kubernetes/pull/108592) added support for Windows
