Upgrade Notes
If you installed RKE2 from RPMs (default on RHEL-based distributions), you will need to either re-run the installer, or edit /etc/yum.repos.d/rancher-rke2.repo to point at the latest/1.20 or stable/1.20 channel (depending on how quickly you would like to receive new releases) in order to update RKE2 via yum.
