A lot of news in amMap v 2.2.0:
Objects can be listed in a drop-down or a list box, a separate group of settings, <object_list> was added to control this drop down. Check World capitals example to see how it works.
Legend can be displayed on top of a map. A separate section of settings, <legend> was added to control the legend.
Instead of lines you can have smoothed curves. The <line> must have at least 3 points to produce a curve.
Balloon can have rounded corners (<corner_radius> setting was added).
The areas and movies can be linked together so that when user rolls-over or clicks on the object some other objects changes the color too.
The default world map is much better calibrated now. The World capitals example uses real longitudes/latitudes for all the cities on the map.
Map of Italy replaced with a much better one.
Also, amMap web site was redesigned, more examples were added!
