Changelog since v1.19.0-alpha.2

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

Kubeadm does not set the deprecated '--cgroup-driver' flag in /var/lib/kubelet/kubeadm-flags.env, it will be set in the kubelet config.yaml. If you have this flag in /var/lib/kubelet/kubeadm-flags.env or /etc/default/kubelet (/etc/sysconfig/kubelet for RPMs) please remove it and set the value using KubeletConfiguration (#90513, @SataQiu) [SIG Cluster Lifecycle]
Kubeadm respects resolvConf value set by user even if systemd-resolved service is active. kubeadm no longer sets the flag in '--resolv-conf' in /var/lib/kubelet/kubeadm-flags.env. If you have this flag in /var/lib/kubelet/kubeadm-flags.env or /etc/default/kubelet (/etc/sysconfig/kubelet for RPMs) please remove it and set the value using KubeletConfiguration (#90394, @SataQiu) [SIG Cluster Lifecycle]
