Domino can show you a rich comparison of the differences between two revisions of a file in your Domino project. To view this comparison, open the file from the Files page and click Compare Revisions.
Domino will open the file comparison tool and display two menus above its contents. The left menu, labeled Base, sets the starting version of the file for your comparison. The other menu, labeled Target, lets you select another version of the file to compare to the base version.
When you are viewing the Files page for your project, you can select between all revisions for the project. When you are viewing an individual file, the revisions dropdown is limited to only those revisions where a change was made to that file.
