The new patch addresses a variety of issues and will further enhance the expansions offerings.
#Civil Wars can no longer go on forever. The side that can hold the capital for six years wins, forcing the rebels to act quickly.
#New interface look, depending on your culture.
#Technology that matters; increased effects of research, and each new level always grants a bonus.
#Rebalanced character loyalty and popularity system. Charisma affects popularity, and ruler popularity affects character loyalty. Watch out for unpopular rulers and heirs...
#More interface improvements, with better tool tips and more messages with logical "Go to" buttons.
#More intrigue at the court; monarchs can have bastards, and the heir apparent has never been more at risk...
