- As in Kubernetes `v1.26` and `v1.27`, resource claims do not get prepared by `kubelet` when no container uses them. This was changed accidentally in [v1.28.0-alpha.1](https://github.com/kubernetes/kubernetes/releases/tag/v1.28.0-alpha.1). ([#118786](https://github.com/kubernetes/kubernetes/pull/118786), [@pohly](https...

- Dynamic resource allocation: will now avoid creating a new gRPC connection for every call of prepare/unprepare resource(s). ([#118619](https://github.com/kubernetes/kubernetes/pull/118619), [@TommyStarK](https://github.com/TommyStarK))

- Kubeadm: removed the EXPERIMENTAL tag from the phase "kubeadm join control-plane-prepare download-certs". ([#124374](https://github.com/kubernetes/kubernetes/pull/124374), [@neolit123](https://github.com/neolit123))

- Improve func `ToSelectableFields`' performance for event. ([#102461](https://github.com/kubernetes/kubernetes/pull/102461), [@goodluckbot](https://github.com/goodluckbot))
- Increased `CSINodeIDMaxLength` from 128 bytes to 192 bytes. Prepare to increase the length limit to 256 bytes in 1.23 release. ([#101256](https://github.com/kubernetes/kubernetes/pull/101256), [@Jiawei0227](https://github.com/Jiawei0227))

- In `kubeadm`, command `kubeadm join phase control-plane-prepare certs` now supports to run with `dry-run` mode on it's own. ([#113005](https://github.com/kubernetes/kubernetes/pull/113005), [@chendave](https://github.com/chendave))

in kubectl, as well as finishing [kubectl diff which is based on server-side dry-run feature](https://kubernetes.io/docs/concepts/overview/working-with-objects/object-management/#how-to-create-objects). We’ve continued separating kubectl code to prepare for extraction out of main repository. Finally, thanks to the awesome support and feedback from community we’ve managed to promote the new [plugin mechanism to Beta](https://kubernetes.io/docs/tasks/extend-kubectl/kubectl-plugins/).
