Well, sort of. You (as owner) have to upgrade your own game to 1.84. Otherwise, it will still process in 1.78. That's fine, unless you/your players want to upgrade. The turn after you order the upgrade is still 1.78 (that's what it was when it was mailed out); the turn it mails out next is 1.84. Hope that's not too confusing (or inaccurate).
