### Kubernetes Node system swap support

Every system administrator or Kubernetes user has been in the same boat regarding setting up and using Kubernetes: disable swap space. With the release of Kubernetes 1.22, *alpha* support is available to run nodes with swap memory. This change lets administrators opt in to configuring swap on Linux nodes, treating a portion of block storage as additional virtual memory.

multiple runtime options to support a variety of workload types.  Examples include native linux containers, and “sandboxed” containers that isolate the container from the host kernel.

The CustomCFSQuotaPeriod alpha feature enables node administrators to change the default period used to enforce CFS quota on a node.  This can improve performance for some workloads that experience latency while using CFS quota with the default measurement period.  Finally, the SIG continues to focus on improving...

- Adds feature gate `NodeLogQuery` which provides cluster administrators with a streaming view of logs using kubectl without them having to implement a client side reader or logging into the node. ([#96120](https://github.com/kubernetes/kubernetes/pull/96120), [@LorbusChris](https://github.com/LorbusChris))

- kube-apiserver: the `NodeRestriction` admission plugin now prevents kubelets from modifying `Node` labels prefixed with `node-restriction.kubernetes.io/`. The `node-restriction.kubernetes.io/` label prefix is reserved for cluster administrators to use for labeling `Node` objects to target workloads to nodes in a way that kubelets cannot modify or spoof.

    * platforms would be satisfied by manually-created PersistentVolume objects.
    * Administrators can choose to disable this behavior by deleting the automatically
    * installed StorageClass API object. Alternatively, administrators may choose to
    * keep the automatically installed StorageClass and only disable the defaulting

* Kubernetes server components using `kubeconfig` files no longer default to `http://localhost:8080`.  Administrators must specify a server value in their kubeconfig files. ([#30808](https://github.com/kubernetes/kubernetes/pull/30808), [@smarterclayton](https://github.com/smarterclayton))

### kube-proxy
* In 1.7, the kube-proxy component has been converted to use a configuration file. The old flags still work in 1.7, but they are being deprecated and will be removed in a future release. Cluster administrators are advised to switch to using the configuration file, but no action is strictly necessary in 1.7.
