It's explained in the read.me text file that come along with civv03.zip

Here are some instances of the modification:

 - To support specialist other than entertainer, city must have population
   at least 5.

 - Under Despotism government, having too many cities may cause unhappy
   citizens to become very unhappy citizens (recognizable by their red shirts).
   To convert them back to normal citizens, they must first be converted into
   normal unhappy citizens (black shirts). This also happens in other types
   of government, but in lesser degree.

 - Imposing martial law (Monarchy/Communism) is limited into three military
   units per city.

 - Renaming city after the city is founded, is made possible.

 - Transport units no longer increase unhappiness under Republic/Democracy.

 - Barracks have their own maintenance costs.
   0/1/2 under level below prince.
   1/2/3 under prince and king level.
   2/3/4 under emperor level.

 - Passing cities by railroad no longer costs 1/3 movement point.

 - Strategy improvement. i.e enemy is now able to move its palace when
   its capitol city is under attack.
