Following is a list of new enhancements and bug fixes in the ArcGIS JavaScript Extension for the Google Maps API, Version 1.4:

Enhancements

• Added support for routing with ArcGIS Server network analysis services. New classes include RouteTask, RouteParameters, DataLayer, NAOutputLine, NAUTurn, Units, RouteResults, RouteResult, and DirectionsFeatureSet. The routing is demonstrated in several new examples in the online SDK.
• Added JSONRequest function to retrieve JSON data from a Web service

Bugs fixed

• Fixed a bug in DynamicMapServiceLayer that caused incorrect positioning of the map image when the map was panned immediately after zooming in
• Fixed a minor bug in the usage of a proxy page for same-origin requests. esri.arcgis.gmaps.Config.proxyUrl is no longer required to have a value when posting a request to the same Web server.
