drupal 'stable' sites upgraded to 5.7

After a succesfull test period on the 'experimental' sites, we have now upgraded the 'stable' sites to drupal5.7. to incorporate imporant security updates, sites were down for only a few seconds. After that, we also performed security upgrades for modules nodewords (meta tags) and archive and a minor update on admin_menu (the pulldown menu for administrators). All should be well, let us know if something inadvertently stopped working on your site.
