has_cap is deprecated since version 2.0.0

Hi and thanks for updating this awesome plugin.

Im still getting an error in my wp-admin, warning me that the plugin is using a deprecated function has_cap.

The error:
Notice: has_cap was called with an argument that is <strong>deprecated</strong> since version 2.0.0! Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead. in /srv/www/planday.com/current/web/wp/wp-includes/functions.php on line 3891

Would be lovely if you could fix that error and update the capabilities checks ??

Thanks!
