Rejoice, people - unit production automation is finally here!
You can set a unit to auto-produce in city menu or country menu. Whenever you have available units, this unit will be built (provided you have enough money). City lists in the country menu and cities menu ('star' in the top toolbar) now show available units or auto-produced unit. Clicking on the unit icon will cancel the auto-production.
In other news, Marines now have the default att: 6 / def: 4. Master Of Stealth increases attack to 7. This makes Marines better in attack, but almost useless in defence - so use them carefully.
Also, numbers have been fixed for USA cities, taking into account metropolitan population. 5 new cities have been added, plus one in Brazil.
