All captured cities will now initially have their income at 20%. It will will increase by 20% each turn you're holding the city. On foreign territory the initial income is 5%, increasing by 5% every turn. After you reach 100%, the increase will be 1%.
This is done to make the transition more realistic and to make players invest in protecting their cities. Once your city income reaches, for example, 120%, you probably wouldn't want it to reset back to 20% (which will happen if another player takes the city).
While it will now take 4 additional turn for your new city to reach its previous potential, it's now possible to go over 100%, and even cities on foreign territory will bring some income as well.
The initial income is now 50% for cities on your territory and 10% on foreign territory. The weekly increase is +25% on your territory until 100% and +2% afterwards, up to the total of 150%. Weekly increase on foreign territory is +5%, and the maximum is 50%.
This change should give enough incentive to hold to your cities, while also not crippling players who prefer rapid expansion.
Also in this release: "/pr Nickname" chat command, for talking to members in private channel. Works the same as choosing from the list, but this also allows you to talk to players in other games, for example. Clicking on player's name in the chat now also puts "/pr Nickname" into the message box.
