The orange circle next to save games,is part of the upgrade.Before you couldn't delete saves from within the game,now you can.The upgrade isn't a patch either bud,it added features which weren't initially part of the engine.Better more effective MGs,graphical tweaks,save deletions,a few customer requested features etc etc.With the upgrade the new features might not seem a lot but they do make a hell of a difference to gameplay.
There's a 2.01 patch to add to the upgrade,so don't forget about that.Have fun bud
P.S. v2.10 will be Market Garden,it's not available patch wise,upgrade wise or module wise.It'll come as Market Garden.
