New function have been added to help control permissions more precisely. This function can change user's role. Therefore now you can use rules to give or reject permissions. For example if you want to take away someone's permissions you can add user to role "forbidden".
- cc - keep informed by email + read-only rights
- contributor - keep informed by email + read-write rights
- reader - read-only rights, without notifications
- forbidden - no access
Note: After you change users role it is stored in database.
