- The `gcp` and `azure` auth plugins have been removed from client-go and kubectl. See https://github.com/Azure/kubelogin and https://cloud.google.com/blog/products/containers-kubernetes/kubectl-auth-changes-in-gke ([#110013](https://github.com/kubernetes/kubernetes/pull/110013), [@enj](https://github.com/enj))

* Flex drivers by default do not produce metrics. Flex plugins can enable metrics collection by setting  the capability 'supportsMetrics' to true. Make sure the file system can support fs stat to produce metrics in this case. ([#67508](https://github.com/kubernetes/kubernetes/pull/67508), [@brahmaroutu](https://github.com/brahmaroutu))

- Pods that are considered for preemption and haven't started don't produce an error log. ([#87900](https://github.com/kubernetes/kubernetes/pull/87900), [@alculquicondor](https://github.com/alculquicondor)) [SIG Scheduling]

- In the course of admitting a single request, the ValidatingAdmissionPolicy plugin will perform no more than one authorization check per unique authorizer expression. All evaluations of identical authorizer expressions will produce the same decision.

- The `gcp` and `azure` auth plugins have been removed from `client-go` and `kubectl`. See [kubelogin](https://github.com/Azure/kubelogin) and [Kubectl Auth Changes in GKE](https://cloud.google.com/blog/products/containers-kubernetes/kubectl-auth-changes-in-gke) for details about the cloud-specific replacements.

### SIG Instrumentation

[SIG Instrumentation][] is responsible for metrics production and
collection.

For the 1.8 release, SIG Instrumentation focused on stabilizing the APIs
and components that are required to support the new version of the Horizontal Pod

* ACTION REQUIRED: Removes defaulting of CSI file system type to ext4. All the production drivers listed under https://kubernetes-csi.github.io/docs/drivers.html were inspected and should not be impacted after this change. If you are using a driver not in that list, please test the drivers on an updated test cluster first. ([#65499]...
