Actually, thinking about this thread(and other one which needs something
similar), i think the best way is not to confuse the 'history/update' with
the actual 'data'; i mean, that history/updates are just for tracking the
revisions, the individual attributes of the entity should be present in the
parent table; and only this parent table should be referred for any 'top' or
'recent' data, as it in its entirety contains the 'present' state of things.

If at all you have to show the revisions/updates/history of the data, then
with the pk from the parent table, query the history table and show the
records.
