    * Note that if you created you config files with `octodns-dump` the records
      are likely already there and match what was configured at the time of the
      dump.
    * Other providers will add root NS support over time once they have had the
      chance to investigate the functionality and implement management if
      possible with whatever accomidations are required.
-   * Once you are using this release and an provider version that supports root
-     NS management you will get errors if you do not have root NS records
-     included by your source(s).
    * Watch your providers README.md and CHANGELOG.md for support and more
      information.
