- This release added support for `NodeExpandSecret` for CSI driver client which enables the CSI drivers to make use of this secret while performing node expansion operation based on the user request. Previously there was no secret  provided as part of the `nodeexpansion` call, thus CSI drivers did not make use of the same while expanding the volume at the node side. ([#105963](https://github.com/kubernetes/kubernetes/pull/105963), [@zhucan](https://github.com/zhucan))...

- When specifying an invalid value for a label, it was not always clear which label the value was specified for. Starting with this release, the label's key is included in such error messages, which makes debugging easier. ([#77144](https://github.com/kubernetes/kubernetes/pull/77144), [@kenegozi](https://github.com/kenegozi))

- Kubeadm: add the RootlessControlPlane kubeadm specific feature gate (Alpha in 1.22, disabled by default).
  It can be used to enable an experimental feature that makes the control plane component static Pod containers 

- The `RemoteRequestHeaderUID` feature moves to beta and is now enabled by default. This makes the kube-apiserver propagate UIDs in the `X-Remote-Uid` header in requests to the aggregated API servers. The header is not honored by default for incoming requests, but that can be enabled by setting the `--requestheader-uid-headers` flag explicitly....

- Added support for installing `arm64` node artifacts. ([#99242](https://github.com/kubernetes/kubernetes/pull/99242), [@liu-cong](https://github.com/liu-cong))

- Make decoding etcd's response respect the timeout context. ([#121815](https://github.com/kubernetes/kubernetes/pull/121815), [@HirazawaUi](https://github.com/HirazawaUi)) [SIG API Machinery]

- Introduce the alpha MutableSchedulingDirectivesForSuspendedJobs feature gate (disabled by default) which:
  1. allows to mutate Job's scheduling directives for suspended Jobs
  2. makes the Job controller to clear the status.startTime field for suspended Jobs ([#135104](https://github.com/kubernetes/kubernetes/pull/135104), [@mimowo](https://github.com/mimowo)) [SIG Apps and Testing]
