Diffing is crucial for effective change management in agile development, allowing developers to reason about previous and upcoming changes, as well as debugging issues. Humanitec has improved its diffing features with new design, layout, and informational value enhancements, providing a categorised overview of updates and displaying changes as a delta in JSON or YAML format. The new diff allows for easier tracking of changes from any point in time, while also enabling developers to create a diff of two previous deployments to understand the evolution of their application. Additionally, Humanitec's diffing features include the ability to generate a diff between any two deployments in a specific environment, making it easier to compare and understand changes made to an application.
