Execution Nodes are now automatically color-coded by Assignment labels. Colors are applied automatically even if no color has been set for an Assignment label, allowing you to track assignments at a glance in both flow view and Swimlane view.
If a color has been set for an Assignment label, that color takes priority. When an Assignment label is created, an unused color is automatically assigned to it, and when it is deleted, that color becomes available for reuse the next time one is created.
