### New Features
#### Assign Multiple MAC Addresses per Interface ([#4867](https://github.com/netbox-community/netbox/issues/4867))
MAC addresses are now managed as independent objects, rather than attributes on device and VM interfaces. NetBox now supports the assignment of multiple MAC addresses per interface, and allows a primary MAC address to be designated for each.
A new UI widget has been introduced to enable conveniently creating new related objects while creating or editing an object. For instance, it is now possible to create and assign a new device role when creating or editing a device from within the device form.
User can now define policies which track the translation of VLAN IDs on IEEE 802.1Q-encapsulated interfaces. Translation policies can be reused across multiple interfaces.
New models have been introduced to support the documentation of virtual circuits as an extension to the physical circuit modeling already supported. This enables users to accurately reflect point-to-point or multipoint virtual circuits atop infrastructure comprising physical circuits and cables.
NetBox now supports the designation of customer VLANs (CVLANs) and service VLANs (SVLANs) to support IEEE 802.1ad/Q-in-Q encapsulation. Each interface can now have it mode designated "Q-in-Q" and be assigned an SVLAN.
