> 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.
