Just ran into this while trying to do some patching:

    *******************************************
    * This script is deprecated and no longer *
    * installs stable releases.               *
    *                                         *
    * The latest edge release has been        *
    * installed. In the future, please use    *
    *   run.linkerd.io/install-edge           *
    * for this behavior.                      *
    *                                         *
    * For stable releases, please see         *
    *  https://linkerd.io/releases/           *
    *******************************************

Bit frustrating, wasn't expecting to have to rework my scripts right now.
