I have CiviCRM for Drupal 7. Just upgraded from 5.4.0 to 5.6.0 via drush. Everything seems OK, including database. Drupal module page shows 7.x-5.6.0. However, CiviCRM status page still thinks that I have 5.4.0 and suggests that I either apply patch to 5.4.1 or upgrade to 5.6.0. I deleted template_c files... How come?
