Manage Member Permissions/Masks?

[The Honor Empire]

I can't seem to find this in the 4.x version. In 3.4.x I have around 20 permission masks that allow specific users access to certain forums. Has that feature been removed from 4.x? Or did I miss a checkbox during the upgrade process?

On my testsite I can see all users are only assigned to their default group. If the permission mask feature has been removed in 4.x, is it possible to have the upgrade auto-create the secondary groups (based on the permission masks from 3.4.x) and assign them to the members as well as have the associated forum permissions (read/write/view/upload/download/etc) assigned to those new secondary groups?

Thanks
