* - unready but creation and last readiness change timestamps are apart more than 10s (pods that have formerly been ready and so metrics are in at least some cases (pod becoming unready because of overload) very useful).
* The `kubectl patch` command no longer exits with exit code 1 when a redundant patch results in a no-op ([#66725](https://github.com/kubernetes/kubernetes/pull/66725), [@juanvallejo](https://github.com/juanvallejo))

### Kubernetes Node system swap support

- Introduction of the pod overhead feature to the scheduler. This functionality is alpha-level as of

      which can be identified by the [node problem detector](http://kubernetes.io/docs/admin/node-problem/)
    * Leaked File descriptors ([#275](https://github.com/docker/containerd/issues/275))
    * Additional memory overhead per container ([#21737](https://github.com/docker/docker/issues/21737))
  * Docker 1.10.3 contains [backports provided by RedHat](https://github.com/docker/docker/compare/v1.10.3...runcom:docker-1.10.3-stable) for known issues

Kubernetes now allows users to define the cluster Service CIDR via an API object: ServiceCIDR.

        - File descriptor leak on init/control.
          ([#275](https://github.com/containerd/containerd/issues/275))

        - Additional memory overhead per container.
          ([#21737](https://github.com/kubernetes/kubernetes/pull/21737))

        - Processes may be leaked when Docker is repeatedly terminated in a short
          time frame.

- Allowed the kubelet to pass Windows GMSA credentials down to Docker ([#73726](https://github.com/kubernetes/kubernetes/pull/73726), [@wk8](https://github.com/wk8))
- Added kube-proxy support for overlay networking and DSR in Windows and new flags for `network-name`, `source-vip`, and `enable-dsr`. ([#70896](https://github.com/kubernetes/kubernetes/pull/70896), [@ksubrmnn](https://github.com/ksubrmnn))

- Added warnings for overlap paths in ConfigMap, Secret, DownwardAPI, Projected. Added warning for cases when ProjectedVolume with sources is provided. ([#121968](https://github.com/kubernetes/kubernetes/pull/121968), [@Peac36](https://github.com/Peac36))

- ResourceQuota of an entity now inclusively calculate Pod overhead ([#99600](https://github.com/kubernetes/kubernetes/pull/99600), [@gjkim42](https://github.com/gjkim42))

- Fix handing special characters in the volume path on Windows ([#99138](https://github.com/kubernetes/kubernetes/pull/99138), [@yujuhong](https://github.com/yujuhong)) [SIG Storage]

### Bug or Regression

- Count pod overhead against an entity's ResourceQuota ([#99600](https://github.com/kubernetes/kubernetes/pull/99600), [@gjkim42](https://github.com/gjkim42)) [SIG API Machinery and Node]
