+* Icinga Web 2 version 2.0.0 requires permissions for accessing modules. Those permissions are automatically generated
+for each installed module in the format `module/<moduleName>`. Administrators have to grant the module permissions to
+users and/or user groups in the roles configuration for permitting access to specific modules.
+In addition, restrictions provided by modules are now configurable for each installed module too. Before,
+a module had to be enabled before having the possibility to configure restrictions.
