After upgrading Harvester from 1.5.0 to 1.5.1 to 1.6.0, I've also upgraded Rancher from 2.11.x to eventually 2.12.1 as well as the Harvester-Addon in Rancher. But one thing that bugs me and I haven't been able to resolve is that the nested-k3s-vcluster is still at k3s-1.28; how do I upgrade that one to a current version (1.33)?
