I have replaced Drupal 7 core files from version 7.10 to 7.12. Now I am running update.php and it displays 3 pending updates, e.g.:
7003 - Add missing custom menus to active menus list
How do I get more information what this means exactly? I checked the site with release notes for Drupal 7.12, but there is no such string (7003) in that list.
