In this scenario, changes are required in all versions of a topic. All versions are in Released state. For the latest version (version 3), you create a new version (version 4). For each of the two earlier versions, version 1 and version 2, you create a new branch, branch 1.1.1 and 2.1.1. Even if the changes required are the same, you must manually make the change in each branch and version.
