 ### Node
 
-Many of the changes within SIG-Node revolve around control. With the beta release of the `kubelet.config.k8s.io` API group, a significant subset of Kubelet configuration can now be [configured via a versioned config file](https://kubernetes.io/docs/tasks/administer-cluster/kubelet-config-file/). Kubernetes v1.10 adds alpha support for the ability to [configure whether containers in a pod should share a single process namespace](https://github.com/kubernetes/enhancements/issues/495), and the CRI has been upgraded to v1alpha2, which adds [support for Windows Container Configuration](https://github.com/kubernetes/enhancements/issues/547). Kubernetes v1.10 also ships with the beta release of the [CRI validation test suite](https://github.com/kubernetes/enhancements/issues/292).

 The Resource Management Working Group graduated three features to beta in the 1.10 release.  First, [CPU Manager](https://kubernetes.io/docs/tasks/administer-cluster/cpu-management-policies/), which allows users to request exclusive CPU cores.  This helps performance in a variety of use-cases, including network latency sensitive applications, as well as applications that benefit from CPU cache residency.  Next, [Huge Pages](https://kubernetes.io/docs/tasks/manage-hugepages/scheduling-hugepages/), which allows pods to consume either 2Mi or 1Gi Huge Pages.  This benefits applications that consume large amounts of memory.  Use of Huge Pages is a common tuning recommendation for databases and JVMs.  Finally, the [Device Plugin](https://kubernetes.io/docs/concepts/cluster-administration/device-plugins/) feature, which provides a framework for vendors to advertise their resources to the Kubelet without changing Kubernetes core code.  Targeted devices include GPUs, High-performance NICs, FPGAs, InfiniBand, and other similar computing resources that may require vendor specific initialization and setup.

 This release brings additional power to both local storage and Persistent Volumes. [Mount namespace propagation](https://github.com/kubernetes/enhancements/issues/432) allows a container to mount a volume as rslave so that host mounts can be seen inside the container, or as rshared so that mounts made inside a container can be seen by the host. (Note that this is [not supported on Windows](https://github.com/kubernetes/kubernetes/pull/60275).) [Local Ephemeral Storage Capacity Isolation](https://github.com/kubernetes/enhancements/issues/361) makes it possible to set requests and limits on ephemeral local storage resources. In addition, you can now create [Local Persistent Storage](https://github.com/kubernetes/enhancements/issues/121), which enables PersistentVolumes to be created with locally attached disks, and not just network volumes.
 
-On the Persistent Volumes side, this release [Prevents deletion of Persistent Volume Claims that are used by a pod](https://github.com/kubernetes/enhancements/issues/498) and [Persistent Volumes that are bound to a Persistent Volume Claim](https://github.com/kubernetes/enhancements/issues/499), making it impossible to delete storage that is in use by a pod.

 This release also includes [Topology Aware Volume Scheduling](https://github.com/kubernetes/enhancements/issues/490) for local persistent volumes, the stable release of [Detailed storage metrics of internal state](https://github.com/kubernetes/enhancements/issues/496), and beta support for [Out-of-tree CSI Volume Plugins](https://github.com/kubernetes/enhancements/issues/178).
