       -  Changed default value of the ``$xss_clean`` parameter to NULL for all methods that utilize it, the default value is now determined by the ``$config['global_xss_filtering']`` setting.
       -  Added method ``post_get()`` and changed ``get_post()`` to search in GET data first. Both methods' names now properly match their GET/POST data search priorities.
       -  Changed method ``_fetch_from_array()`` to parse array notation in field name.
+      -  Changed method ``_fetch_from_array()`` to allow retrieving multiple fields at once by passing $index as an array.
       -  Added an option for ``_clean_input_keys()`` to return FALSE instead of terminating the whole script.
       -  Deprecated the ``is_cli_request()`` method, it is now an alias for the new :func:`is_cli()` common function.
       -  Added an ``$xss_clean`` parameter to method ``user_agent()`` and removed the ``$user_agent`` property.
