I am working on my preliminary release. And I found that Auditing gets turned on automatically when you build the release version.
Things of note:
You have to manually populate the metaEntityClass, metaEntityProperty, metaEntityPropertyView (not sure what this one is for) tables with your entities.
If anyone has implemented Auditing I would like to hear what they are doing with it.
I am planning on tracking the changes and having changes, not made by a certain user role, require approval before it is committed to the database.
