deprecated notice when debugging

When using this plugin in debug mode I get the following notice:

Notice: has_cap was called with an argument that is deprecated since version 2.0! Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead. in /home/bitnami/wordpress/wp-includes/functions.php on line 3844

I have traced this to lines 7-8 of the admin/options.php script, which should read:

add_options_page('Cross Post', 'Cross Post Options', 'edit_pages',
            'cross_post_options', 'cross_post_options_page');

Maybe you could consider including this in the next update of this plugin?
