have a couple more screenshots of the IS-6 and M53/M55 armor comparison between 9.13 and 9.14.
-Driver's hatch is now 110 mm instead of 90 mm and its view port is now smaller.
-On top of turret, 2 viewports are gone and the remaining one got shrunk.
-Engine Bay "crater" is now tighter
-Spare tracks are giving an extra 20 mm or armor on the back side of the hull and tracks are now firmly close to the hull body (this is what happens when you take stairs instead of elevator).
A Nerf, armor was kept the same but effective armor has lost some value, also, the recoil spade (or "garden bench" as I like to call) is now being held by necromantic spells (this is normal in arty models).
