This update is for everyone who plays a country in Lead Mode. The world stops picking fights with you for no reason and building buildings is now easier.
No more surprise wars
On Easy and Normal, countries no longer declare war on you out of nowhere. They need a reason first:
the wars you start
your conquests near their borders
your nukes landing close to them
Behave, and their worries fade over time. A country on the other side of the map that never shared a border with you has no reason to attack you anymore. The country panel now tells you when a country is wary of you, and when it sees you as a threat, so a war never comes as a surprise. This was something a reviewer noticed and now it's been balanced.
On Hard, nothing changes: you are just another country.
Faster building

Brush: pick a building, switch to Brush and drag across the map. Every region you cross gets it.
Build to level: choose Level 1, 2, 3 or Max, and each site keeps upgrading by itself as soon as the next upgrade can start and you can pay for it.
Waiting work: with the brush, regions you cannot afford yet wait in a queue and are built when the money comes in. You can cancel the waiting work at any time.
Your buildings: the Build list now shows every building type you own, and Level up all upgrades them in one click, biggest regions first.
Max level: development technology raises the highest building level past 3. The Max button shows how far you can go.

Also new
Military and development technology now show a bar with how close each is to its next level.
The world population counter now shows trillions instead of "1000 billion"
