* kubectl built for darwin from darwin now enables cgo to use the system-native C libraries for DNS resolution. Cross-compiled kubectl (e.g. from an official kubernetes release) still uses the go-native netgo DNS implementation.  ([#64219](https://github.com/kubernetes/kubernetes/pull/64219), [@ixdy](https://github.com/ixdy))

  - Add support for journald.
  - The ability to monitor any system daemon logs. Previously only kernel
    logs were supported.
  - The ability to be deployed and run as a native daemon.
* **[alpha]** Critical Pods: When feature gate "ExperimentalCriticalPodAnnotation" is
  set to true, the system will guarantee scheduling and admission of pods with

consistency and security, Kubernetes performs pruning, or the automatic removal of unknown fields in objects sent to a Kubernetes API. An "unknown" field is one that is not specified in the OpenAPI validation schema. This behavior is already in place for native resources and ensures only data structures specified by the CRD developer are persisted to etcd.

Pruning is activated by setting `spec.preserveUnknownFields: false` in the Cu...

### Windows

* kubelet and kube-proxy can now be run as native Windows services. ([#60144](https://github.com/kubernetes/kubernetes/pull/60144), [@alinbalutoiu](https://github.com/alinbalutoiu))

Two alpha features were also added in this release.

The RuntimeClass alpha feature enables a node to surface multiple runtime options to support a variety of workload types.  Examples include native linux containers, and “sandboxed” containers that isolate the container from the host kernel.
