Tip

Plugin maintainers: Please see the dedicated plugin migration guide for a checklist of changes that may be needed to ensure compatibility with NetBox v4.0.

Breaking Changes

  • Support for Python 3.8 and 3.9 has been removed.
  • The format for GraphQL query filters has changed. Please see the GraphQL documentation for details and examples.
  • The deprecated device_role & device_role_id filters for devices have been removed. (Use role and role_id instead.)
  • The obsolete device_role field has been removed from the REST API serializer for devices. (Use role instead.)
  • The legacy reports functionality has been dropped. Reports will be automatically converted to custom scripts on upgrade.
  • The parent and parent_id filters for locations now return only immediate children of the specified location. (Use ancestor and ancestor_id to return all descendants.)
  • The object_type field on the CustomField model has been renamed to related_object_type.
  • The utilities.utils module has been removed and its resources reorganized into separate modules organized by function.
  • The obsolete NullableCharField class has been removed. (Use Django's stock CharField class with null=True instead.)

New Features

Complete UI Refresh (#12128)

The NetBox user interface has been completely refreshed and updated. This massive effort entailed:

  • Refactoring the base HTML templates
  • Moving from Boostrap 5.0 to Bootstrap 5.3
  • Adopting the Tabler UI theme
  • Replacing slim-select with Tom-Select
  • Displaying additional object attributes in dropdown form fields
  • Enabling opt-in HTMX-powered navigation (see #14736)
  • Widespread cleanup & standardization of UI components

Dynamic REST API Fields (#15087)

The REST API now supports specifying which fields to include in the response data. For example, the response to a request for

GET /api/dcim/sites/?fields=name,status,region,tenant

will include only the four specified fields in the representation of each site. Additionally, the underlying database queries effected by such requests have been optimized to omit fields which are not included in the response, resulting in a substantial performance improvement.

Strawberry GraphQL Engine (#9856)

The GraphQL engine has been changed from using Graphene-Django to Strawberry-Django. Changes include:

  • Queryset Optimizer - reduces the number of database queries when querying related tables
  • Updated GraphiQL Browser
  • The format for GraphQL query filters and lookups has changed. Please see the GraphQL documentation for details and examples.

Advanced Form Rendering Functionality (#14739)

New resources have been introduced to enable advanced form rendering without a need for custom HTML templates. These include:

  • FieldSet - Represents a grouping of form fields (replaces the use of lists/tuples)
  • InlineFields - Multiple fields rendered on a single row
  • TabbedGroups - Fieldsets rendered under navigable tabs within a form
  • ObjectAttribute - Renders a read-only representation of a particular object attribute (for reference)

Legacy Admin UI Disabled (#12325)

The legacy admin user interface is now disabled by default, and the few remaining views it provided have been relocated to the primary UI. NetBox deployments which still depend on the legacy admin functionality for plugins can enable it by setting the DJANGO_ADMIN_ENABLED configuration parameter to true.
