@@ -17,6 +17,13 @@ The following updates do **not** trigger message bus notifications:
- Moving objects in the 3D Viewport.
- Changes performed by the animation system.
Changes done from ``msgbus`` callbacks are not included in related undo steps,
so users can easily skip their effects by using Undo followed by Redo.
Unlike properties ``update`` callbacks, message bus update callbacks are postponed
until all operators have finished executing.
Additionally, for each property the callback is only triggered once per update cycle,
even if the property was changed multiple times during that period.
