Class Jetpack_Geo_Location is deprecated since version 14.3 with no alternative

I have a PHP application which authenticates users against WordPress by using

define('WP_USE_THEMES', false);
require_once 'wp-load.php';

Ever since I upgraded from Jetpack 14.2.1 to 14.3 I have been getting this error notice:

E_USER_DEPRECATED in /home/mysite/public_html/wp-includes/functions.php at line 6114
