contextual_help is Deprecated

Can the plugin be updated so that those with WP_DEBUG set to true do not see this error?

Deprecated: contextual_help is deprecated since version 3.3.0! Use get_current_screen()->add_help_tab(), get_current_screen()->remove_help_tab() instead.

I think it’s related to this line:
add_filter( ‘contextual_help’, array( __CLASS__, ‘show_contextual_help’ ), 10, 3 );
