 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.

+Since edge releases are not semantically versioned, it is possible for the supported Kubernetes versions to change at any given edge release.
