WHAT'S CHANGED SINCE 1.12.0

 - Citizen Management Agent (CMA) allows you to automate workers
   and specialists in cities.
 - Sound support has been added.
 - The new "isotrident" tileset has been made the default. The
   "hires" and "engels" tilesets have been taken out of the
   distribution but can be downloaded from the web page.
 - New city dialog in the gtk client.
 - Windows version of the client. It has improved connection
   dialog and supports loading and saving from the client.
 - GTK 2.0 version of the client.
 - The client will try to suggest names for your cities that 
   correspond with what they mean.
 - Improved players dialog shows sortable and colored information,
   including the players' flags.
 - Server no longer takes the --server command line option,
   instead you can use the --info option to set the metaserver
   announcement text to whatever you like. The -a option when given
   to the client skips the connection dialog entirely.
 - A "wall" server command added which gives message to all players.
 - A new flexible timeout set through "timeoutinc" server option.
 - Leftover research bulbs will carry over to next advance.

   have their firepower reduced to 1 against fighter units.
 - You can build city walls even though you have Great Wall wonder.
 - The Communism government's food cost in default ruleset has
   been changed to 1, while it has been changed to 2 for the Civ2
   ruleset.

   partially invisible just like subs. Also, stealth bombers have
   increased their attack strength from 14 to 18.

 - Improved modpack abilities: The caravan ability has been split.
   New ways to calculate technology costs. Better documentation.
   Rulesets can specify starting techs. You can have more than one
   bonus tech. Split settler abilities. Buildings ruleset syntax

   "separatepoles" allow continents connected to the poles

   "notradesize" and "fulltradesize" regulate the trade generated 
   by smaller cities.
 - You can turn on angry citizens with "angrycitizens" option.
