Caution

This is a beta release of NetBox intended for testing and evaluation. Do not use this software in production. Also be aware that no upgrade path is provided to future releases.

New Features

Virtual Machine Types (#5795)

A new VirtualMachineType model has been introduced to enable categorization of virtual machines by instance type, analogous to how DeviceType categorizes physical hardware. VM types can be defined once and reused across many virtual machines.

Cable Bundles (#20151)

A new CableBundle model allows individual cables to be grouped together to represent physical cable runs that are managed as a unit; e.g. a bundle of 48 CAT6 cables between two patch panels. (Please note that this feature is not suitable for modeling individual fiber strands within a single cable.)

Rack Groups (#20961)

A flat RackGroup model has been reintroduced to provide a lightweight secondary axis of rack organization (e.g. by row or aisle) that is independent of the location hierarchy. Racks carry an optional foreign key to a RackGroup, and RackGroup can also serve as a scope for VLANGroup assignments.

ETag Support for REST API (#21356)

The REST API now returns an ETag header on responses for individual objects, derived from the object's last-updated timestamp. Clients can supply an If-Match header on PUT/PATCH requests to guard against conflicting concurrent updates; if the object has been modified since the ETag was issued, the server returns a 412 (Precondition Failed) response.

Cursor-based Pagination for REST API (#21363)

A new start query parameter has been introduced as an efficient alternative to the existing offset parameter for paginating large result sets. Rather than scanning the table up to a relative offset, the start parameter filters for objects with a primary key equal to or greater than the given value, enabling constant-time pagination regardless of result set size.
