I guess most importantly tanks have had their move increased by one point. Likewise have most aircrafts also got their operational range increased.
Else I have done a lot of balancing of the unit strenghts, and to tell you the truth, I cannot remember all the minor changes. Though I can reveal to you Voltar, that the Wehrmacht divisions has got slightly better attack strenght and the Stuka bombers are now cheaper to build.
Right now I make a lot of changes to the scenario, so be prepared for more updates, especially on the rules.txt.
