In this scenario, changes are required in version 3 of a topic for a reissue of a publication. Version 3 is the latest version of the topic, and it is in the Released state. When you need to update the latest version of a released object, create a new version.
Note:
You technically can create a branch from the latest version for maintenance updates. But when it’s time to create the next version, you have to remember to do create it from the previous full version and not from the branch (you can’t create a version 3 from branch 2.1.1). And any changes that you made to the branch will not be included in the new version and will have to be added manually. So this is not recommended.
You can create a new version of an object that is in Draft state. You might want to do this if you are still working on one release but starting work on the next release. But, for any changes that apply to both versions, you will have to make those changes manually in both versions. To minimize maintenance, we recommend waiting until the first version is as stable as possible before you create the new version.
