  // Set this value longer than the expected cleanup time for your process.
  // If this value is nil, the pod's terminationGracePeriodSeconds will be used. Otherwise, this
  // value overrides the value provided by the pod spec.
  // Value must be non-negative integer. The value zero indicates stop immediately via

* Add Post-bind extension point to the scheduling framework ([#77567](https://github.com/kubernetes/kubernetes/pull/77567), [@wgliang](https://github.com/wgliang))

* New Kubelet flag `--enforce-node-allocatable` with a default value of `pods` is added which will make kubelet create a top level cgroup for all pods to enforce Node Allocatable. Optionally, `system-reserved` & `kube-reserved` values can also be specified separated by comma to enforce node allocatable on cgroups specified via `--system-reserved-cgroup` & `--kube-reserved-cgroup` respectively. Note the default value of the latter flags are "". ([#41234](https://github.com/kubernetes/kub...

*   If multiple PodSecurityPolicy objects allow a submitted pod, priority is given to policies that do not require default values for any fields in the pod spec. If default values are required, the first policy ordered by name that allows the pod is used. ([#52849](https://github.com/kubernetes/kubernetes/pull/52849),[ @liggitt](https://github.com/liggitt))

  It may affect some metrics values related to the `NodeAffinity` Filter plugin. ([#114125](https://github.com/kubernetes/kubernetes/pull/114125), [@sanposhiho](https://github.com/sanposhiho))
- Scheduler now skips `InterPodAffinity` Filter plugin when `InterPodAffinity` Filter plugin has nothing to do with a Pod.

    * Add support for enumerations in *path operation* parameters. New documentation: [Path Parameters: Predefined values](https://fastapi.tiangolo.com/tutorial/path-params/#predefined-values).

* Default values differ between the Kubelet's componentconfig (config file) API and the Kubelet's command line. Be sure to review the default values when migrating to using a config file. For example, the authz mode is set to "AlwaysAllow" if you rely on the command line, but defaults to the more secure "Webhook" mode if you load...

- The "value" part in the `wait --for=jsonpath='{expression}'[=value]` is now
  optional. If the value is not provided i.e., the command looks like `wait --for=jsonpath='{expression}'`
  then the wait condition is interpreted as matched when the expression returns
