• Improved AI for economy and military matters
• Economy system rebalanced, with support for proper free-market adaption
• New system for how gun boat diplomacy and bankruptcies work
• Socialists can now back political reforms and Liberals can do social reforms (though each less than the other)
• Pop promotion and assimilation have received a major overhaul
• Artillery is now a more useful unit, and mobilization does not punish sparsely populated countries as much
• Many bug fixes, game balance tweaks and interface improvements
