We need to be able to specify a log message when making changes (any changes) to a topic.
We also need to be able to view the list of revisions on each topic (not the diffs) just the messages, the user that made the change, and the date/time. (ideally in the future clicking on each item would display the diff of those changes some how)
Envers supports this functionality: http://docs.jboss.org/hibernate/envers/3.6/reference/en-US/html_single/#revisionlog
This would be useful for QE to match the log with the versions quoted in Bugzille bugs, and becomes necessary for situations where multiple authors/teams/products use the same topic or topic cluster.
This has now been implemented.
