- Fixed a performance issue where pods weren't created/deleted in parallel for a StatefulSet with podManagementPolicy: Parallel. ([#119096](https://github.com/kubernetes/kubernetes/pull/119096), [@aleksandra-malinowska](https://github.com/aleksandra-malinowska)) [SIG Apps]

- For volumes that allow attaches across multiple nodes, attach and detach operations across different nodes are now executed in parallel. ([#88678](https://github.com/kubernetes/kubernetes/pull/88678), [@verult](https://github.com/verult)) [SIG Storage]

* StatefulSets now include an alpha scaling feature accessible by setting the `spec.podManagementPolicy` field to `Parallel`.  The controller will not wait for pods to be ready before adding the other pods, and will replace deleted pods as needed.  Since parallel scaling creates pods out of order, you cannot depend on predictable membership changes within your set. ([#44899](https://github.com/kubernetes/kubernetes/pull/44899), [@smart...

- Fixed a 1.28.0 regression where kube-controller-manager can crash when StatefulSet with Parallel policy and PVC labels is scaled up. ([#121184](https://github.com/kubernetes/kubernetes/pull/121184), [@aleksandra-malinowska](https://github.com/aleksandra-malinowska)) [SIG Apps]

  - Introduce a new label "node-role.kubernetes.io/control-plane" that will be applied in parallel to "node-role.kubernetes.io/master" until the removal of the "node-role.kubernetes.io/master" label.

- Add --permit-address-sharing flag to `kube-apiserver` to listen with `SO_REUSEADDR`. While allowing to listen on wildcard IPs like 0.0.0.0 and specific IPs in parallel, it avoids waiting for the kernel to release socket in `TIME_WAIT` state, and hence, considerably reducing `kube-apiserver` restart times under certain conditions.
