There are three significant changes that I have seen so far:
Axis mobile divisions start split up, which means they now mostly take 3MPs on new road instead of 2MPs, so quite a hit for Axis.
One turn less of free rail conversion.
Soviets no longer have supply sources spread all over the map, so more chances to pocket units later into the game and less ports to take care of.
Lots of other changes, and no doubt many that with my limited experience of D21 that am not aware of.
Looks like a good improvement !
Am playing with the PO on +1.
Situation at the start of T3. Rail heads marked.
AGN. A few hexes from Riga, have got Courland cut off.
AGC. Heading for Minsk, there is no supply point in the city. A couple of large pockets on the border.
AGS. Pushing the rail line through the marshes towards Kiev, just hope the PO doesn't react and block it. Will start another rail line from the Romanian border and take that to Odessa. Have got L'Vov cut off, last turn there were heavy tank counter attacks near Brody but this turn they have settled down and will hoopefully surrender quietly.
One possible update - the German cavalry division is the old colour.
