- new : external authentication in another users table. Previous users table

is divided between users (common properties with any web application) and
  user_infos (phpwebgallery specific informations). External table and
  fields can be configured.

- modification : profile.php is not reachable through administration anymore
  (not useful).

- modification : in profile.php, current password is mandatory only if user
  tries to change his password. Username can't be changed.

- deletion : of obsolete functions get_user_restrictions,
  update_user_restrictions, get_user_all_restrictions, is_user_allowed,
  update_user

- modification : $user['forbidden_categories'] equals at least "-1" so that
  category_id NOT IN ($user['forbidden_categories']) can always be used.

- modification : user_forbidden table becomes user_cache so that not only
  restriction informations can be stored in this table.
