- new : maintenance screen in administration. There you can update

categories informations (number of images, date of the last added
  element), update images informations (path, average rate), purge obsolete
  sessions, purge history.

- new : ability to have random representative for categories. This
  configuration parameter is set to false by default.

- new : ability to set an element as representative of a category without
  belonging to the category. Thus, administrator can choose representative
  even for empty categories.

- improvement : semantically superior design for category edition screen by
  regrouping fields in fieldsets. The improved screen contains action
  buttons as in category list screen.

- new : ability to move a virtual category (ie change its parent category).

- bug fixed : the sync_users function checks all user children tables
  (access, cache, group association).
