### CSIDriver policy for FSGroup graduates to Beta

The FSGroup's CSIDriver Policy is now beta in 1.20. This allows CSIDrivers to explicitly indicate if they want Kubernetes to manage permissions and ownership for their volumes via `fsgroup`. 

### Security Improvements for CSI Drivers (Alpha)

  - `timeout` default changed from `30s` to `10s` for v1
  - `sideEffects` default value is removed, and the field made required, and only `None` and `NoneOnDryRun` are permitted for v1
  - `admissionReviewVersions` default value is removed and the field made required for v1 (supported versions for AdmissionReview are `v1` and `v1beta1`)

- Allow kubectl to manage resources by filename patterns without the shell expanding it first ([#102265](https://github.com/kubernetes/kubernetes/pull/102265), [@danielrodriguez](https://github.com/danielrodriguez))

### Server-side Apply graduates to GA

supports node proxying, which allows clients of kube-apiserver to access endpoints of a Kubelet to establish connections to Pods, retrieve container logs, and more. While Kubernetes already validates the proxying address for Nodes, a bug in kube-apiserver made it possible to bypass this validation. Bypassing this validation could allow authenticated requests destined for Nodes to be redirected to the API Server through its private network.

The merged fix enforces validation against the proxying...

- Fixes a regression in the pod binding subresource to honor the `metadata.uid` precondition.
  This allows kube-scheduler to ensure it is assigns node names to the same instances of pods it made scheduling decisions for. ([#116776](https://github.com/kubernetes/kubernetes/pull/116776), [@alculquicondor](https://github.com/alculquicondor)) [SIG API Machinery and Testing]

* DaemonSets [can now be updated by a rolling update](https://kubernetes.io/docs/tasks/manage-daemon/update-daemon-set).

## Action Required

### Certificates API

* Fix a scalability issue where high rates of event writes degraded etcd performance. ([#64539](https://github.com/kubernetes/kubernetes/pull/64539), [@ccding](https://github.com/ccding))
* Properly manage security groups for loadbalancer services on OpenStack. ([#65373](https://github.com/kubernetes/kubernetes/pull/65373), [@multi-io](https://github.com/multi-io))

upgrading, and deleting clusters.

For the 1.8 release, SIG Cluster Lifecycle continued to focus on expanding the
capabilities of kubeadm, which is both a user-facing tool to manage clusters
and a building block for higher-level provisioning systems. Starting
with the 1.8 release, kubeadm supports a new upgrade command and includes alpha
support for self hosting the cluster control plane.
