HeatmapRenderer no longer in beta

New constructor option and method to declare color ramp.

var heatmapRenderer = new HeatmapRenderer({
  blurRadius: 10,
  minPixelIntensity: 1,
  colorStops: [
        {ratio: 0, color:"rgba(0, 255, 0, 0)"},
        {ratio:0.3, color:"rgb(0, 255, 0)"},
        {ratio:0.4, color:"rgb(150, 255, 0)"},
        {ratio:0.5, color:"rgb(255, 255, 0)"},
        {ratio:0.85, color:"rgb(255, 95, 0)"},
        {ratio:1, color:"rgb(255, 0, 0)"}
    ]
});

featureLayer.setRenderer(heatmapRenderer);

New basemaps

Support for two new basemap options in the API: Terrain and Dark Gray. The latter is a completely new base map on ArcGIS Online.

DataAdapterFeatureLayer and LocationProvider classes (beta)

This new layer type allows developers to easily visualize data based upon standard levels of geography such as county, zip code, and census tract or blockgroup by leveraging LocationProvider based classes.  This enhancement will easily allow third-party business systems to geo-enable their data easily. For more information, see the DataAdapterFeatureLayer and the LocationProvider classes in the API Reference.
