+=head3 Backwards compatibility note
+
+The render method used to just return the Template::Exception object, rather
+than just throwing it. This is now deprecated and instead the render method
+will throw an exception for new applications.
+
+This behaviour can be activated (and is activated in the default skeleton
+configuration) by using C<< render_die => 1 >>. If you rely on the legacy
+behaviour then a warning will be issued.
+
+To silence this warning, set C<< render_die => 0 >>, but it is recommended
+you adjust your code so that it works with C<< render_die => 1 >>.
+
+In a future release, C<< render_die => 1 >> will become the default if
+unspecified.
