Which feature in AEM provides a comprehensive history of changes made in different versions of a page?

The feature in Adobe Experience Manager (AEM) that provides a comprehensive history of changes made in different versions of a page is the page comparison and diff view. This functionality allows users to visually compare different versions of a page side-by-side, highlighting the differences between them. It enables content authors and editors to see what specific changes have been made, such as text updates, image modifications, or layout alterations. This not only aids in understanding the evolution of the page over time, but it also helps in ensuring that any changes align with content strategies and quality standards.

While options like the History Viewer, Change Log, and Versioning Notification may offer some insights into changes, they do not provide the detailed, visual representation of changes that the page comparison and diff view does. This comprehensive view is particularly beneficial for teams working collaboratively on content, as it enhances communication and accuracy in content management.
