Deprication warning

I get the following warning when running admin with DEBUG flag on:

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 …\site\wp-includes\functions.php on line 3193

Changing the following:

public function adminMenu()
    {
        add_options_page(
            'Search Exclude',
            'Search Exclude',
            10,
            'search_exclude',
            array($this, 'options')
        );
    }

to:

public function adminMenu()
    {
        add_options_page(
            'Search Exclude',
            'Search Exclude',
            'manage_options',
            'search_exclude',
            array($this, 'options')
        );
    }

fixes the issue.
