Diagrams
The diagrams were subjected to a big overhaul in Collibra Platform 5.1/2025.04 and their functionality and design have been improved extensively. However, most of the Diagram related APIs are non-public. Therefore, these changes do not have much impact on the v1 public API.
The biggest change is in the format that is being used for the configuration of the diagram views. The JSON syntax used in 5.1/2025.04 is updated from the syntax used in 4.5x, 4.6.x or 5.0.
The configuration of a diagram view remains in a JSON format though and has no immediate impact on the method in the public API.
