one minor point that players may not be aware of, that did not make it into the change list (I think):
In campaign games, when buying your support troops, you now have the option of spending accumulated build/repair points to buy support troops. An increment of 1000 build points expended buys 750 support troop points for this battle (i.e. there is a premium on the exchange rate

.
It obviously does not apply in battle No. 1 of a campaign as you will have accumulated none.
The button is where "MAX POINTS" appears in normal battle generator battles, i.e. at the bottom of the central block, with "VIEW MAP" etc.
Could be useful if you have a battered core in say a special battle with no repair (to buy support troops to take the heat

, but remember that repair points used now, will not be available to fix units later..
Cheers
