lets see... things I've noticed quickly through a skim as changes. (taken in from the units page...) Maybe like an unofficial patch changes which granted is stupid seeing as they're coming up but I'll just do it anyway...
Virtually all abilities now cost munitions such as the Command Squad's Light artillery barrage
Conscript Cost Reduced to 217 and 7 man squad. Throw molotov now costs 10 munitions
Guards PPS-43 now costs 65 munitions. SVT-40 package costs 75. Leader starts with SVT-40. Both types of grenades cost 25 munitions. Smoke grenades are free.
Ingenery now cost 152 manpower. New "Assault Gear" upgrade for 100 manpower and 75 munitions. Dual ROKS-3 also available.
Sniper Precision Artillery now costs 150 munitions
New "Shtrafnyie Troops". Role detailed as basic Infantry. Armed with PPSh-41s and mosin nagants. A 6 population (presumably 6 man because of the 20 manpower reinforcement cost) squad costing 168 manpower. "Discipline" ability.
Sniper Ace now costs 700 manpower. Suppression shot costs 50 munitions, Precision Artillery costs 150 munitions, and One Man Army costs 50 munitions.
Strelky get the Stand Your Ground! ability
ZiS Support Gun now costs 290 manpower
IS-3 costs 500 manpower
ISU-152 gets "BLANK" ability. (Presumably not filled in yet.)
KV-1s (might have already been like this) are 10 population
KV-2 is 750 manpower
SU-122 has cage armor upgrade for 75 munitions
SU-76 costs 320 manpower and 50 fuel
SU-85 now seems to be a 600 manpower call-in
Well these are the things I've caught. Probably a few mistakes
but whatever...
