 for users of the community-owned package repositories hosted at `pkgs.k8s.io`.

+This step is only needed upon upgrading a cluster to another **minor** release.
+If you're upgrading to another patch release within the same minor release (e.g.
+v{{< skew currentVersion >}}.5 to v{{< skew currentVersion >}}.7), you don't
+need to follow this guide. However, if you're still using the legacy package
+repositories, you'll need to migrate to the new community-owned package
+repositories before upgrading (see the next section for more details on how to
+do this).
