This release of Cells Enteprise (only) fixes two annoying bugs with external directories (manual roles lost after sync) and license statistics (sometimes hanging the UX in Address Book).
This should be necessary only for clients having very large number of users ( > 10 000, generally imported from LDAP/AD directory).
Use the in-app tool for automatically upgrading the binary, then restart your service. Do not forget the `setcap` command if you are listening to port 80 or 443 before restarting!
