This is primarily a bugfix release.


  • Documented all nodes and plugs.
  • Improved Reference workflow
    • Boxes exported for referencing contain new default values for all promoted plugs to match their current values on the Box.
    • When reloading a reference, only values the user has changed from their defaults will be kept. Other values will be updated from the new reference.
    • Box metadata is included when exporting for referencing. This means that colours and descriptions set via the UIEditor will be transferred onto any Reference nodes which load the exported reference (#1171).
