v12.0.0

[12.0.0] - 2026-09-04

This release supports NetBox 4.7.x only. Deployments on NetBox 4.5 or 4.6 should stay on the 11.x line.

Changed

• Compatibility window moved to NetBox 4.7.x (min_version = "4.7.0", max_version = "4.7.99"). NetBox 4.7.0 refused to load the plugin because of the previous 4.6.99 ceiling (issue #116).
• List views declare their actions as ObjectAction classes from netbox.object_actions. NetBox 4.7 dropped the shim that translated the legacy dict form, so the bump alone would have raised AttributeError on every attachment and assignment list page.
• Django requirement raised to >=6.1, matching NetBox 4.7.
• Migration 0012 now records related_name="+" on NetBoxAttachment.owner, matching the change NetBox 4.7 made to OwnerMixin. No schema change; existing installs are unaffected.
• Removed a redundant objects manager on NetBoxAttachmentAssignment (NetBoxModel already provides the same RestrictedQuerySet manager) and a stray __init__.py in the templates directory. No behavior change.

Removed

• The ObjectTypeField serializer shim. NetBox 4.7's ContentTypeField resolves against the field's declared queryset, so the cast to ObjectType is no longer needed.

Fixed

• Custom fields are now exposed by the REST API serializers for both NetBoxAttachment and NetBoxAttachmentAssignment. They were omitted from the serializers' fields list, which DRF drops silently (the field is declared on a NetBox base class, exempting it from the "declared fields must be listed" assertion) — so custom fields were editable in the UI but invisible and unwritable through the API.
