* New alpha feature limits the number of processes running in a pod. Cluster administrators will be able to place limits by using the new kubelet command line parameter --pod-max-pids. Note that since this is a alpha feature they will need to enable the "SupportPodPidsLimit" feature. By default, we do not set any maximum limit, If an administrator wants to enable this, they should enable SupportPodPidsLimit=true in the --feature-gates= parameter to kubelet and...

- Kubelet.exe on Windows now checks that the process running as administrator and the executing user account is listed in the built-in administrators group.  This is the equivalent to checking the process is running as uid 0.

### 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.

    /** The key of the configuration. e.g. [a-zA-Z0-9_]+ */
    String USER_CODE_PATTERN = "user.code.pattern";

    /** The key of the configuration. e.g. Administrator */
    String MAIL_FROM_NAME = "mail.from.name";

    /** The key of the configuration. e.g. root@localhost */
    String MAIL_FROM_ADDRESS = "mail.from.address";

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...

- 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.
