According to the change log, these are the main features:

• Added preliminary User/Groups management support. (You can create users and groups, relate them and login using those credentials, but there's no privileges scheme yet.)
• The server and the client can reside in diferent computers. At login time you can choose a different WSDL location.
• Added toolbars and in general, the elements were rearranged.
• Inline edition for object nodes names.
• Multiple bugfixes.
• Built on top of the NetBeans Platform that is included in NetBeans IDE 6.9 (Build 201006101454).
• This version comes with three databases as described in the README file of the server package: kuwaibadb_empty.backup is a db with the classmetadata, but no objects created or containment hierarchy defined, kuwaibadb_container_hierarchy.backup is a db with a basic containment hierarchy defined and kuwaibadb_test_data.backup is the same as the previous one but with demo data inside. Use this if you want to get started with the system.

The default login/password is admin/kuwaiba but you can change it anytime using the user management section (Ctrl+U).
