* 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))

    *   Extends the device plugin checkpoint data to record registered resources so that we can finish resource removing devices even upon kubelet restarts.
    *   Passes sourcesReady from kubelet to the device plugin to avoid removing inactive pods during the grace period of kubelet restart.

- Fix kubelet to not leak goroutines/intofiy watchers on an inactive connection if it's closed ([#67285](https://github.com/kubernetes/kubernetes/pull/67285), [@yujuhong](https://github.com/yujuhong))

  - 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. It will be available as a beta feature in Kubernetes 1.15.

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

  - The `--deserialization-cache-size` flag is deprecated, and will be removed in a future release. The flag is inactive since the etcd2 storage backend was removed. ([#69842](https://github.com/kubernetes/kubernetes/pull/69842), [@liggitt](https://github.com/liggitt))

    * [StorageOS](http://www.storageos.com) can be used as a storage provider for Kubernetes.  With StorageOS, capacity from local or attached storage is pooled across the cluster, providing converged infrastructure for cloud-native applications.
* CRI has been moved to package `pkg/kubelet/apis/cri/v1alpha1/runtime`. ([#47113](https://github.com/kubernetes/kubernetes/pull/47113), [@feiskyer](https://github.com/feiskyer))

### 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))
