The Permissions property was relocated to Role components (new in
In order to migrate Users from

This one-to-one mapping of created roles to users is shown above, where user JohnW has (by default), only one role assigned: also named JohnW. (Note additional roles could be assigned, but are not here.) Effectively, nothing changed here: the permissions map that used to be in user JohnW’s permissions property is now in the “same named” Role component.

As shown above, you can see this in the popup Edit window for each Role (in the Role Manager view on the RoleService). The role now has the permissions map.
In summary, to make better use of roles, you should consider this a workaround effect of migration. For example, you could create more duty specific roles and/or rename or delete roles, later reassigning to users in various combinations. When adding or editing users, this can simplify how permissions are assigned.
The Role Manager lets you do all these things, except the assignment of one or more roles to users. That you do from editing (or adding new) users in the User Manager, or from User property sheets.
