    There is no replacement.

    There is a non-public API in the ObjectStore that provides access to
    the ObjectDiff:

    ObjectDiff diff = dataContext.getObjectStore().getChangesByObjectId
    ().get(oid);
    Object oldValue = diff.getSnapshotValue("property");

    You can use it by creating your own utility class in the
    org.objectstyle.cayenne.access package. But use it at your own risk,
    as non-public methods are not guaranteed to be preserved (or even
    deprecated properly).
