+Step 3: Remove usage of $config['standardize_newlines']
+=======================================================
+
+The :doc:`Input Library <../libraries/input>` would optionally replace
+occurences of `\r\n`, `\r`, `\n` in input data with whatever the ``PHP_EOL``
+value is on your system - if you've set ``$config['standardize_newlines']``
+to ``TRUE`` in your *application/config/config.php*.
+
+This functionality is now deprecated and scheduled for removal in
+CodeIgniter 3.2.+.
