- Refactored `test/e2e/framework` so that the core framework is smaller. Optional functionality like resource monitoring, log size monitoring, metrics gathering and debug information dumping must be imported by specific e2e test suites. Init packages are provided which can be imported to re-enable the functionality that traditionally was in the core framework. If you have code that no longer compiles because of this PR, you can use the script [from a commit message](https://git...

- 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))

* ResourceQuota ability to support default limited resources ([#36765](https://github.com/kubernetes/kubernetes/pull/36765), [@derekwaynecarr](https://github.com/derekwaynecarr))
* Fix kubemark default e2e test suite's name ([#41751](https://github.com/kubernetes/kubernetes/pull/41751), [@shyamjvs](https://github.com/shyamjvs))

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...

Kubernetes v1.10 also ships with the beta release of the [CRI validation test suite](https://github.com/kubernetes/enhancements/issues/292).

The Resource Management Working Group graduated three features to beta in the 1.10 release.  First, [CPU Manager](https://kubernetes.io/docs/tasks/administer-cluster/cpu-management-policies/),...

* 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))

* E2E tests no longer add command line flags directly to the command line, test suites that want that need to be updated if they don't use HandleFlags ([#75593](https://github.com/kubernetes/kubernetes/pull/75593), [@pohly](https://github.com/pohly))

    cuDNN R4
