Version 3.4 of the Yahoo! AJAX Maps comes with great additions that make it very tempting to upgrade, which is not required if you don't want to take advantage of the added functionality. The new features include polyline overlays, an option to export GeoRSS from a map, traffic overlays (which is already possible in the Flash version), and more.

Interested? Have a look at the documentation or the Local blog.
