New Kharkov '43 Campaign

[BigDuke66]

Bought K43 in the recent sale and it's a nice bonus to see how much in was again improved. The notes are impressive.
But I would like to know if these changes are only for the new Grand Campaign Variant 2 or if they, were applicable, are also being added to the smaller campaigns respectively smaller scenarios. Would be a pity if the improvements were confined to only the new scenario.
