v0.2.2

0.2.2 — 2026-09-11

• The diagram editor toolbar has a Fullscreen button that puts the draw.io iframe into
  native browser fullscreen. Esc returns to the normal layout.

v0.2.1

0.2.1 — 2026-09-10

• Diagram previews are now browser-cacheable: every <img> links the SVG endpoint with
  ?v=<content_hash> and the endpoint answers such requests with
  Cache-Control: private, max-age=31536000, immutable, so a list of 150 diagrams costs 150
  requests once instead of on every page load. Unversioned URLs keep revalidating via ETag.
• The SVG endpoint checks If-None-Match before loading the SVG blob, so a 304 no longer reads
  the diagram out of Postgres.
• List and tab querysets compute svg_size with OCTET_LENGTH instead of LENGTH, which avoids
  decompressing every stored SVG just to test whether a preview exists.

v0.2.0

0.2.0 — 2026-09-04

• Breaking: requires NetBox 4.7.x (min_version 4.7.0, max_version 4.7.99). NetBox 4.6.x
  installs stay on 0.1.x.
• Verified against NetBox 4.7.0 (Django 6.1, django-tables2 3.0): no code or migration changes.
  List-view / API query-count baselines re-recorded (NetBox 4.7 issues fewer queries per request).

v0.1.1

• Fix save being silently dropped when a draw.io spinner was already active (two saves in quick succession, autosave during a manual save): the export request no longer sets spinKey, so draw.io's spinner guard can't swallow it (#4).
• The status line now shows Saving… as soon as a save is requested, so a stalled export is visible.

Full Changelog: v0.1.0...v0.1.1

v0.1.0

First public release. Requires NetBox 4.6.4 – 4.6.99, Python ≥ 3.12, < 3.15.

pip install netbox-drawio

On PyPI: https://pypi.org/project/netbox-drawio/

Features

• Embedded draw.io editor using the draw.io embed protocol — diagram XML travels only between
  the browser and NetBox; the editor host never receives it.
• Diagrams tab on object detail pages with SVG preview cards, per-card edit / unlink
  actions, and Add Diagram / Link Existing buttons.
• Many-to-many assignment: one diagram links to any number of objects of any enabled type.
• SVG previews served from a hardened endpoint (CSP, sandbox, nosniff; rendered via <img>
  so embedded scripts can never execute).
• .drawio source download.
• REST API for diagrams and assignments; the diagram list response omits the source_xml /
  svg_cache blobs.
• Global search, change logging (content blobs excluded; a content_hash records every content
  change), tags, custom fields, journaling, and object permissions.
• Configurable editor URL and query params, autosave, model scoping (applied_scope,
  scope_filter, excluded_apps, excluded_models), tab placement, and a byte cap on
  diagram XML and SVG.
