Release v4.2.0

[jeremystretch]

Breaking Changes

• Support for the Django admin UI has been completely removed. (The Django admin UI was disabled by default in NetBox v4.0.)
• NetBox has adopted collation-based natural ordering for many models. This may alter the order in which some objects are listed by default.
• Automatic redirects from pre-v4.1 UI views for virtual disks have been removed.
• The site and provider_network foreign key fields on circuits.CircuitTermination have been replaced by the termination generic foreign key.
• The site foreign key field on ipam.Prefix has been replaced by the scope generic foreign key.
• The site foreign key field on virtualization.Cluster has been replaced by the scope generic foreign key.
• The circuit foreign key field on circuits.CircuitGroupAssignment has been replaced by the member generic foreign key.
• Obsolete nested REST API serializers have been removed. These were deprecated in NetBox v4.1 under #17143.

New Features

Assign Multiple MAC Addresses per Interface (#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.

Quick Add UI Widget (#5858)

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.

VLAN Translation (#7336)

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.

Virtual Circuits (#13086)

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.

Q-in-Q Encapsulation (#13428)

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.
