+This addition introduced the need for a way to describe subjects as combinations of multiple attributes of different types (interface, certificate common name, and/or username). 
 We have addressed this need by reworking the ACL configuration format, making it modular by isolating the `rules` from the `subjects`. 
 This allows the combination of subject attributes, while also avoiding the need to duplicate subject or rule configurations by adding the `policies` list.
