A new major revision of Live Maps was released today, with a number of new features and enhancements.  At the top of the list is Firefox (v 1.5 or later) support for 3D mapping.  In addition, memory management and cache performance has been improved for the IE version.  3D support is now also included for the Space Navigator, a 3D controller made by 3dConnexion, a Logitech company.
