- Client-go: fixes potential data races retrying requests using a custom io.Reader body; with this fix, only requests with no body or with string / []byte / runtime.Object bodies can be retried ([#113933](https://github.com/kubernetes/kubernetes/pull/113933),...

- Fixed a bug that an init container with containerRestartPolicy with `Always` cannot update its state from terminated to non-terminated for the pod with restartPolicy with `Never` or `OnFailure`. ([#123710](https://github.com/kubernetes/kubernetes/pull/123710), [@gjkim42](https://github.com/gjkim42)) [SIG Apps]

and PVC objects can be deleted properly.

* Use of subPath module with hostPath volumes can cause issues during reconstruction ([#61446](https://github.com/kubernetes/kubernetes/issues/61446)) and with containerized kubelets ([#61456](https://github.com/kubernetes/kubernetes/issues/61456)). The workaround for this issue is to specify the complete path in the hostPath volume. Use of subPathmounts nested within atomic writer volumes (configmap, secret, downwardAPI, projected) does not work...

### Failing Test

- Fixed generic ephemeal volumes with OwnerReferencesPermissionEnforcement admission plugin enabled. ([#101186](https://github.com/kubernetes/kubernetes/pull/101186), [@jsafrane](https://github.com/jsafrane)) [SIG Auth and Storage]

#### **Hardware Accelerators**

* Update cluster-proportional-autoscaler, metadata-proxy, and fluentd-gcp addons with fixes for CVE-2016-4448, CVE-2016-8859, CVE-2016-9841, CVE-2016-9843, and CVE-2017-9526. ([#47545](https://github.com/kubernetes/kubernetes/pull/47545), [@ixdy](https://github.com/ixdy))

- With this new stable feature, Kubernetes supports the scaling of containerized applications with Azure VMSS, including the ability to integrate it with cluster-autoscaler to automatically adjust the size of the Kubernetes clusters based on the same conditions.

### SIG-cli

- Fixes a problem with 63-second or 1-second connection delays with some VXLAN-based
  network plugins which was first widely noticed in 1.16 (though some users saw it
  earlier than that, possibly only with specific network plugins). If you were previously
  using ethtool to disable checksum offload on your primary network interface, you should

* APIServices with kube-like versions (e.g. `v1`, `v2beta1`, etc.) will be sorted appropriately within each group.  ([#64004](https://github.com/kubernetes/kubernetes/pull/64004), [@mbohlool](https://github.com/mbohlool))
