A short introduction on how to work with different versions of documentation for a Maven plugin.
Unversioned Title
The current version is typically represented by an unversioned title.
The generated pages will have a "(Current Version)" marker in their title.
Previous versions can be easily added to the same space using the Version doctype. This will import metadata from the maven plugin artifact with the version number as part of each page title (for instance "POM (1.2.0)").
Next Version
To add a new version the current tree of versioned information should be copied and the "(Current Version)" should be replaced by this version's version number.
Then delete the tree and import the metadata of the new version by using the Version doctype. This time use check the Unversioned Title checkbox (as has been the case when the space has been created).
