### SIG Multi-cluster (formerly known as SIG Federation)

  * For StatefulSet (previously PetSet), this change means creation of
    replacement pods is blocked until old pods are definitely not running
    (indicated either by the kubelet returning from partitioned state,
    deletion of the Node object, deletion of the instance in the cloud provider,

These extension points can now be abstracted away due to their irrelevance for most users.

### CSI Migration updates

CSI Migration enables the replacement of existing in-tree storage plugins such as `kubernetes.io/gce-pd` or `kubernetes.io/aws-ebs` with a corresponding CSI driver.
If CSI Migration is working properly, Kubernetes end users shouldn’t notice a difference.

- Promoted Job Pod Replacement Policy to general availability. The `JobPodReplacementPolicy` feature gate was locked to `true` and will be removed in a future Kubernetes release. ([#132173](https://github.com/kubernetes/kubernetes/pull/132173), [@dejanzele](https://github.com/dejanzele))...

- Fixed CEL estimated cost of `replace()` to handle a zero length replacement string correctly.
  Previously this would cause the estimated cost to be higher than it should be. ([#120097](https://github.com/kubernetes/kubernetes/pull/120097), [@jpbetz](https://github.com/jpbetz)) [SIG API Machinery]

### Registry
* Use daemonset in docker registry add on ([#35582](https://github.com/kubernetes/kubernetes/pull/35582), [@surajssd](https://github.com/surajssd))
* contribute deis/registry-proxy as a replacement for kube-registry-proxy ([#35797](https://github.com/kubernetes/kubernetes/pull/35797), [@bacongobbler](https://github.com/bacongobbler))
