Do you know what backward compatibility is?

Backward compatibility is a property of a system or product to maintain correct operation with older versions of data, interfaces, or components. For example, if a new version of a software product can work with files created in previous versions or supports old APIs, then it is backward compatible.

For a product, this is important so that users can update without losing data and functionality, and integrations with other systems do not break. In analytics, this is considered when planning changes and releasing new versions to minimize risks and ensure a smooth transition.
