+Input library method is_cli_request()
+=====================================
+
+Calls to the ``CI_Input::is_cli_request()`` method are necessary at many places
+in the CodeIgniter internals and this is often before the :doc:`Input Library
+<../libraries/input>` is loaded. Because of that, it is being replaced by a common
+function named :php:func:`is_cli()` and this method is now just an alias.

+The new function is both available at all times for you to use and shorter to type.
