What feature would you use to view the differences between two versions of a microflow?

The correct choice is the Diff viewer. This feature is specifically designed to highlight the differences between two versions of a microflow, which allows developers to identify what has changed between the versions effectively. The Diff viewer presents a side-by-side comparison of the two microflow versions, showing additions, deletions, and modifications in a clear manner. This is particularly useful for version control and understanding the evolution of your application logic.

While there are other options like version comparison or change log, they do not provide the same focused visual representation of differences within a microflow. A change log typically summarizes changes across versions but does not offer a detailed, graphical comparison. Similarly, the history tracker may record actions taken but lacks the functionality dedicated to comparing versions directly in a visual format. The Diff viewer is thus the essential tool when needing to understand specific alterations made in the flow logic of a microflow.
