### Windows

This release continues to enable more existing features on Windows, including container CPU resources, image filesystem stats, and flexvolumes. It also adds Windows service control manager support and experimental support for Hyper-V isolation of single-container pods.

### OpenStack

- Potentially breaking change - Updating the polling interval for Windows stats collection from 1 second to 10 seconds ([#116546](https://github.com/kubernetes/kubernetes/pull/116546), [@marosset](https://github.com/marosset)) [SIG Node and Windows]

- Added support for pod `hostNetwork` field selector ([#110477](https://github.com/kubernetes/kubernetes/pull/110477), [@halfcrazy](https://github.com/halfcrazy)) [SIG Apps and Node]
- Added swap to stats to Summary API and Prometheus endpoints (stats/summary and /metrics/resource). ([#118865](https://github.com/kubernetes/kubernetes/pull/118865), [@iholder101](https://github.com/iholder101))

- Kubelet now attempts to get an existing node if the request to create it fails with StatusForbidden. ([#126318](https://github.com/kubernetes/kubernetes/pull/126318), [@hoskeri](https://github.com/hoskeri)) [SIG Node]
- Kubelet: use the CRI stats provider if `PodAndContainerStatsFromCRI` feature is enabled ([#126488](https://github.com/kubernetes/kubernetes/pull/126488), [@haircommander](https://github.com/haircommander)) [SIG Node]

- Kubelet/stats: set INFO log level for stats not found in cadvisor memory cache error. ([#125656](https://github.com/kubernetes/kubernetes/pull/125656), [@gyuho](https://github.com/gyuho))

* Windows container configuration in CRI is now considered beta ([ref](https://github.com/kubernetes/enhancements/issues/547))
* CRI logging and stats are now considered beta ([ref](https://github.com/kubernetes/enhancements/issues/552))

  E0303 17:25:03.436781 63839 summary_sys_containers.go:47] Failed to get system container stats for "/docker": failed to get cgroup stats for "/docker": failed to get container info for "/docker": unknown container "/docker"

* Bumped Heapster version to 1.4.1: ([#50642](https://github.com/kubernetes/kubernetes/pull/50642), [@piosz](https://github.com/piosz))
    * handle gracefully problem when kubelet reports duplicated stats for the same container (see [#47853](https://github.com/kubernetes/kubernetes/pull/47853)) on Heapster side
    * fixed bugs and improved performance in Stackdriver Sink

## API Changes

*   Rename `SqueezeDims` attribute to `Axis` in C++ API for Squeeze op.
*   `Stream::BlockHostUntilDone` now returns Status rather than bool.
*   Minor refactor: move stats files from `stochastic` to `common` and remove
    `stochastic`.

## Known Bugs

*   Using XLA:GPU with CUDA 9 and CUDA 9.1 results in garbage results and/or
    `CUDA_ILLEGAL_ADDRESS` failures.
