0.80.0

UI

• NodeGraph now only drag-selects nodes that are wholly contained in the drag area, not merely intersecting it.
• Added a Backdrop node (#153).

RenderMan

• Added support for “help” shader annotation in RenderManShaderUI (#536). This provides help for the shader as a whole and is mapped into the MetaData as the node description, appearing in the NodeEditor as a tooltip.

API

• Added optional continuous update to string PlugValueWidgets, controlled by the continuousUpdate parameters to the constructor. This transfers the text from the ui to the plug on every keypress.

Core

• Fixed serialisation of dynamic BoxPlugs.

Documentation

• Improvements too numerous to mention.
