k3s seems to be still using 1.5 series containerd. Is there something preventing versionup to 1.6? I noticed there’s 1.6.6 tag in the fork repo, but there doesn’t seem to be k3s release using this one. Also, is there some documentation regarding the differences between official containerd and the fork?

The most recent round of release notes have been incorrect. K3s 1.24 is linked against containerd 1.5 for reasons, but bundles 1.6
