-       `v1.0.0 <https://github.com/saltstack-formulas/nginx-formula/releases/tag/v1.0.0>`_,
-       this formula provided two methods for managing NGINX;
-       the old method under ``nginx`` and the new method under ``nginx.ng``.
-       The old method has now been removed and ``nginx.ng`` has been promoted to
-       be ``nginx`` in its place.
-
-       If you are not in a position to migrate, please pin your repo to the final
-       release tag before
-       `v1.0.0 <https://github.com/saltstack-formulas/nginx-formula/releases/tag/v1.0.0>`_,
-       i.e.
-       `v0.56.1 <https://github.com/saltstack-formulas/nginx-formula/releases/tag/v0.56.1>`_.
-
-       To migrate from ``nginx.ng``, simply modify your pillar to promote the
-       entire section under ``nginx:ng`` so that it is under ``nginx`` instead.
-       So with the editor of your choice, highlight the entire section and then
-       unindent one level.  Finish by removing the ``ng:`` line.
-
-       To migrate from the old ``nginx``, first convert to ``nginx.ng`` under
-       `v0.56.1 <https://github.com/saltstack-formulas/nginx-formula/releases/tag/v0.56.1>`_
-       and then follow the steps laid out in the paragraph directly above.
