### kubeadm

- Kubeadm:  'kubeadm alpha kubelet config download' has been removed, please use 'kubeadm upgrade node phase kubelet-config' instead ([#87944](https://github.com/kubernetes/kubernetes/pull/87944), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

- Kubeadm: remove 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)) [SIG Cluster Lifecycle]

(N-3). This aligns with the recent change made by SIG Architecture that extends the support skew between the control plane and kubelets. Tolerate this new kubelet skew for the commands `init`, `join` and `upgrade`. Note that if the `kubeadm` user applies a control plane version that is older than the `kubeadm` version (N-1 maximum) then the skew between the kubelet and control plane would become a maximum of N-2.

### Feature

- Add flag --lease-max-object-size and metric etcd_lease_object_counts for kube-apiserver to config and observe max objects attached to a single etcd lease. ([#97480](https://github.com/kubernetes/kubernetes/pull/97480), [@lingsamuel](https://github.com/lingsamuel)) [SIG API Machinery, Instrumentation and Scalability]

Kubernetes' default backend storage, etcd, has a new release 3.5.0 and the community embraced it. The new release comes with improvements to the Security, performance, monitoring and developer experience. There are numerous bug fixes to lease objects causing memory leaks, and compact operation causing deadlocks and more. A couple of new features are also introduced like the migration to structured logging and build in log rotation. The release comes with a detailed future roadmap to implement a solution...
