+properties are now used for the device link step.
+
+In CMake 3.17 and below, link options are not used by the device link step.
+
+The ``OLD`` behavior for this policy is to ignore the link options.
+
+The ``NEW`` behavior of this policy is to use the link options during the
+device link step.
+
+This policy was introduced in CMake version 3.17.  Use the
+:command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
+Unlike many policies, CMake version |release| does *not* warn
+when this policy is not set and simply uses ``OLD`` behavior.
