 Use the :command:`cmake_minimum_required` command to record the latest
 version of CMake for which a project has been updated.
-The ``VERSION <min>...<policy_max>`` syntax enables the ``NEW`` behaviors

+This uses the ``<min>...<max>`` syntax to enable the ``NEW`` behaviors
+of policies introduced in CMake 3.31 and earlier while only requiring a
+minimum version of CMake 3.10.  The project is expected to work with
+both the ``OLD`` and ``NEW`` behaviors of policies introduced between
