- Fixes a kube-apiserver log volume regression bug in default 1.27 configurations (introduced in 1.26, activated by the AggregatedDiscoveryEndpoint feature enablement in 1.27) ([#122074](https://github.com/kubernetes/kubernetes/pull/122074), [@ritazh](https://github.com/ritazh)) [SIG API Machinery]

*   The admission webhook configurations API, part of the admissionregistration API, is now at v1beta1. Delete any existing webhook configurations before you upgrade, and update your configuration files to use the latest API. For this and the previous change, see also [the documentation](https://kubernetes.io/docs/admin/extensible-admission-controllers/#exter...

- New Metrics Added for Encryption Configuration Controller
  
  This release adds new metrics to the Encryption Configuration Controller to help monitor the automatic reloading of encryption configuration. The new metrics include:
  
  - `apiserver_encryption_config_controller_automatic_reload_failures_total`: Total number of failed automatic reloads of encryption configuration.

- `audit.k8s.io/v1beta1` and `audit.k8s.io/v1alpha1` audit policy configuration and audit events are deprecated in favor of `audit.k8s.io/v1`, available since v1.13. kube-apiserver invocations that specify alpha or beta policy configurations with `--audit-policy-file`, or explicitly request alpha or beta audit events with `--audit-log-version` / `--audit-webhook-version` must update to use `audit.k8s.io/v1`...

  - support for the `v1alpha3` configuration file format is deprecated and will be removed in 1.14. Use `kubeadm config migrate` to migrate `v1alpha3` configuration files to `v1beta1`, which provides improvements in image repository management, addons configuration, and other areas. The documentation for `v1beta1` can be found here: https://godoc.org/k8s.io/kubernetes/cmd/kubeadm/app/apis/kubeadm/v1beta1...

kube-scheduler policy config via SCHEDULER_POLICY_CONFIG. This allows us to specify a customized scheduler policy configuration. ([#57425](https://github.com/kubernetes/kubernetes/pull/57425), [@yguo0905](https://github.com/yguo0905))

* Returns an error for non overcommitable resources if they don't have limit field set in container spec to prevent users from creating invalid configurations. ([#57170](https://github.com/kubernetes/kubernetes/pull/57170), [@jiayingz](https://github.com/jiayingz))...

* kubeadm now uses an upgraded API version for the configuration file, `kubeadm.k8s.io/v1alpha2`. kubeadm in v1.11 will still be able to read `v1alpha1` configuration, and will automatically convert the configuration to `v1alpha2`, both internally and when storing the configuration in the ConfigMap in the cluster.
