  When an Indexed Job has a number of completions higher than 10^5 and parallelism higher than 10^4, and a big number of Indexes fail, Kubernetes might not be able to track the termination of the Job. Kubernetes now emits a warning, at Job creation, when the Job manifest exceeds both of these limits.

  - The `--experimental-encryption-provider-config` flag is deprecated in favor of `--encryption-provider-config`. The old flag is accepted with a warning but will be removed in 1.14. ([#71206](https://github.com/kubernetes/kubernetes/pull/71206),...

- e2e storage tests now run faster and are easier to read ([#72434](https://github.com/kubernetes/kubernetes/pull/72434), [@pohly](https://github.com/pohly))
- `e2e.test` now rejects unknown `--provider` values instead of merely warning about them. An empty provider name is not accepted anymore and was replaced by `skeleton` (a provider with no special behavior).

  Don't use these flags. Using deprecated flags causes the server to print a warning. Using a removed flag causes the server to abort the startup.

* The following deprecated flags were removed from `kubelet`:

  * `api-servers` - add apiserver addresses to the kubeconfig file instead.

  Don't use these flags. Using deprecated flags causes the kubelet to print a warning. Using a removed flag causes the kubelet to abort the startup.

For new clusters if you have not configured the cgroup driver explicitly you might get a failure in the `kubelet` on driver mismatch (kubeadm clusters should be using the `systemd` driver). Also remove the `IsDockerSystemdCheck` preflight check (warning) that checks if the Docker cgroup driver is set to `systemd`. Ideally such detection / coordination should be on the side of CRI implementers and the kubelet (tracked [here](https://github.com/kubernetes/kubernetes/issues/99808)). Please see the ...
