Tiger II:
AOE distance from 1/2/3 to 0/1/4
AOE damage from 1/0.35/0.05 to 0.75/0.25/0.125
Scatter angle from 7.5 to 5.
What is AOE distance, AOE damage, Scatter angle ? what's those three value means? 1/2/3
damage is a multiplier to the cannon damage, distance is the distance from the impact point. There are near, mid and far reference points.
So for example for the Tiger as above it means that the Tiger does 75% damage (multiplier = 0,75) at 0 meters, 25% damage at 1 meter and 12,5% at 4 meters. So if you calculate the AoE damage 1 meter from the impact, it would be gun 160*0,25 = 40 damage (160 is the base damage of the gun).
All other points (for example 3 meters etc) are interpolated.
Maybe have a look at that:

Scatter is a parameter that determines by how far the tank will miss if it does not hit the intended spot. Higher means the shot will land further off.
Sturm Offizier:
Veterancy 4: -29% Received Accuracy
What is negative Received Accuracy?
Received accuracy (RA) is a modifier to modify the chance of being hit. So if a Gren would have a weapon accuracy of 50% (so every second shot hits), then this is modified by the RA of the targeted squad. If the targeted squad would have a RA of 2, then it would be hit with 50%*2 = 100% chance. Negatve RA means that the squad becomes better. For example if the base RA would be 1 and the vet bonus like above -29% RA, then the squad would have 0,71 RA left.
Cover for example gives you reduced RA as well. Less is of course better.
Cromwell:
Target size from 22 to 20
what is Target Size?
Basically RA for tanks.
The chance to hit is calculated as:
base accuracy*target size*RA
the base accuracy depends on the distance. Tanks have base accuracies of about 2-5%. So if we assume a tank with 2% base accuracy shots at the new Cromwell, the Cromwell would have a natural chance to be hit in 2%*20 = 40% of all shots.
"Unnatural" hits are if the game calculates a miss, but the target is still hit due to projectile collision with hit boxes.
Sniper:
Wind down increased from 4 to 4.5.
what is Wind down?
As far as I know it's one of the times that is needed after the Sniper has taken a shot. The chance above will decrease the ROF by half a second.
Command Panzer IV:
Aura damage reduction modifier from 0.8 to 0.9, as was previously intended.
What is Aura damage?
All allied tanks near the Command P4 in vertain range will receive lower damage. So the Command P4 has an "aura" around it where it buffs tanks. And these tanks will only receive 90% of the damage now that they're supposed to get, unlike 80% as previously.
