+Step 2: Remove usage of CAPTCHA helper extra parameters (deprecation)
+=====================================================================
+
+The :doc:`CAPTCHA Helper <../helpers/captcha_helper>` function
+:php:func:`create_captcha()` allows passing of its ``img_path``, ``img_url``
+and ``font_path`` options as the 2nd, 3rd and 4th parameters respectively.
+
+This kind of usage is now deprecated and you should just pass the options
+in question as part of the first parameter array.
+
+.. note:: The functionality in question is still available, but you're
+ strongly encouraged to remove its usage sooner rather than later.
