* Third Party Resource tests in the e2e suite were incorrectly marked as part of the conformance bucket.  They are alpha and are not required for conformance. ([#52823](https://github.com/kubernetes/kubernetes/pull/52823), [@smarterclayton](https://github.com/smarterclayton))

- The e2e suite can be instructed not to wait for pods in kube-system to be ready or for all nodes to be ready by passing `--allowed-not-ready-nodes=-1` when invoking the e2e.test program. This allows callers to run subsets of the e2e suite in scenarios other than perfectly healthy clusters. ([#98781](https://github.com/kubernetes/kubernetes/pull/98781), [@smarterclayton](...

providers today. This involved auditing the cloud provider APIs for anything that should be deprecated as well as adding changes where necessary. In addition, SIG Cloud Provider has begun exploratory work around having a “cloud provider” e2e test suite which can be used to test common cloud provider functionalities with resources such as nodes and load balancers.

We are also continuing our long running effort to extract all the existing cloud providers that live in k8s.io/kubernetes...

- Introduced end-to-end tests to verify component invariant metrics across the entire test suite. ([#133394](https://github.com/kubernetes/kubernetes/pull/133394), [@BenTheElder](https://github.com/BenTheElder))
- Introduced new kubelet metrics for the Ensure Secret Pulled Images KEP, including:

- Adding `--restart-kubelet` flag on E2E Node test suite ([#97028](https://github.com/kubernetes/kubernetes/pull/97028), [@knabben](https://github.com/knabben)) [SIG Node and Testing]
- Adds feature gate `KubeletInUserNamespace` which enables support for running kubelet in a user namespace.

* Respect graceful pod termination of up to 10 minutes
* Handle zone stock-outs and failures
* Improve monitoring and error reporting

#### Container Runtime Interface (CRI)

* [alpha] Add a CRI validation test suite and CRI command-line tools. ([#292](https://github.com/kubernetes/enhancements/issues/292), [@feiskyer](https://github.com/feiskyer))

- Total test spec is now available by `ProgressReporter`, it will be reported before test suite got executed. ([#114417](https://github.com/kubernetes/kubernetes/pull/114417), [@chendave](https://github.com/chendave))

- The `GetAllocatableResources` podresources API endpoint is now GA. ([#118973](https://github.com/kubernetes/kubernetes/pull/118973), [@ffromani](https://github.com/ffromani))
- 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))

capability to beta, allowing users to use the familiar `kubeadm init` and `kubeadm join` commands to [configure and deploy an HA control plane](https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/high-availability/). An entire new test suite has been created specifically for ensuring these features will stay stable over time.

Certificate management has become more robust in 1.15, with kubeadm now seamlessly rotating all your certificates (on upgrades) before they expire. Check...

* ClusterRole aggregation is now GA ([ref](https://github.com/kubernetes/enhancements/issues/502))
* CRI validation test suite is now GA ([ref](https://github.com/kubernetes/enhancements/issues/292))
