Storing information about changes of properties
-----------------------------------------------

                 Key: HHH-6605
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6605
             Project: Hibernate Core
          Issue Type: New Feature
          Components: envers
    Affects Versions: 4.x
            Reporter: Michał Skowronek


Users would be able to construct more meaningful audit queries if Envers had an option to store and query information about modifications of individual properties, e.g.:

getAuditReader().createQuery().forRevisionsOfEntity(clazz, false, false)
		.add(AuditEntity.id().eq(id)).add(AuditEntity.property(propertyName).hasChanged());

With such a query, user will get only those revisions of (clazz, id), that modified property with propertyName.
Currently, to achieve that, user have to retrieve and compare manually two revisions, which increases complexity and decreases performance.
