has been deprecated as part of the deprecation of Heapster. Instead, you may use the [metrics server](https://github.com/kubernetes-incubator/metrics-server). It's a simplified heapster that is able to gather and serve current metrics values. It provides the Metrics API that is used by `kubectl top`, and horizontal pod autoscaler. Note that it doesn't include some features of Heapster, such as short term metrics for graphs in kube-dashboard and dedicated push sinks, which proved hard to maintain and...

PodSecurityPolicy was initially [deprecated in v1.21](/blog/2021/04/06/podsecuritypolicy-deprecation-past-present-and-future/), and with the release of v1.25, it has been removed. The updates required to improve its usability would have introduced breaking changes, so it became necessary to remove it in favor of a more friendly replacement. That replacement is [Pod Security Admission](/docs/concepts/security/pod-security-admission/), which graduates to Stable with this release....

* Fixes bug in DaemonSetController causing it to stop processing some DaemonSets for 5 minutes after node removal. ([#76060](https://github.com/kubernetes/kubernetes/pull/76060), [@krzysztof-jastrzebski](https://github.com/krzysztof-jastrzebski))
* Check if container memory stats are available before accessing it ([#77656](https://github.com/kubernetes/kubernetes/pull/77656), [@yastij](https://github.com/yastij))

- The feature gate was mentioned as `csiMigrationRBD` where it should have been `CSIMigrationRBD` to be in parity with other migration plugins. This release correct the same and keep it as `CSIMigrationRBD`.
  

  - true/strict - perform validation and error the request on any invalid fields in the ojbect. It will attempt to perform server-side validation if it is enabled on the apiserver, otherwise it will fall back to client-side validation.

  // manually, the requested family is available in the cluster,
  // and ipFamilyPolicy allows it, it will be used; otherwise creation of
  // the service will fail. This field is conditionally mutable: it allows
  // for adding or removing a secondary IP family, but it does not allow
  // changing the primary IP family of the Service. Valid values are "IPv4"

  patches up a race condition between when a pod is killed and when the external load
  balancer notices that it has been killed. ([#97238](https://github.com/kubernetes/kubernetes/pull/97238), [@andrewsykim](https://github.com/andrewsykim))

    - make kube::util::find-binary return an error when it doesn't find
      anything so that hack scripts fail fast instead of with "binary not
      found errors".
    - this required deleting some genfeddoc stuff. the binary no longer
      exists in k/k repo since we removed federation/, and I don't see it
      in https://github.com/kubernetes-sigs/kubefed/ either. I'm assuming
      that it's gone for good now.
