- It is now possible to upload certificates required to join a new control-plane to kubeadm-certs secret using the flag `--experimental-upload-certs` on `init` or upload-certs phase. ([#73907](https://github.com/kubernetes/kubernetes/pull/73907), [@yagonobre](https://github.com/yagonobre))

  in kube-apisever and kube-controller-manager pods. Instead, it shifted to supporting the
  mounting of /etc/pki/ca-trust and /etc/pki/tls/certs. The locations /etc/ca-certificate,
  /usr/share/ca-certificates, /usr/local/share/ca-certificates, and /etc/ssl/certs continued
  to be supported. ([#124361](https://github.com/kubernetes/kubernetes/pull/124361), [@neolit123](https://github.com/neolit123))

* On cluster provision or upgrade, kubeadm now generates certs and secures all connections to the etcd static-pod with mTLS. This includes the etcd serving cert, the etcd peer cert, and the apiserver etcd client cert. Flags and hostMounts are added to the etcd and apiserver static-pods to load these certs. For connections to etcd, https is now used in favor of http. ([#57415](https://github.com/kubernetes/kubernetes/pull/57415),...
