changes that cause older versions of Linkerd to not work: we will update the

Note that Linkerd will almost never change the supported Kubernetes version in
a minor release, which is why the table above only lists major versions. One
known exception: Linkerd 2.11.0 supported Kubernetes 1.16, but 2.11.1 and
later required Kubernetes 1.17 as shown in the table above.
