What's new in Version 3.9

CSV Layer

New CSVLayer class to easily display data from CSV files on a map. See the CSV Layer sample for an example of how to use this new layer. If CSV files are not on the same domain as your website, a CORS enabled server or a proxy is required.

Query Enhancements

New capabilities when querying against a layer in a hosted feature service in ArcGIS Online:

Continuous Color

Renderers' colorInfo property and setColorInfo method now support more than two colors as well as a stops property that allows developers to associate a specific color with a data value. The legend widget also now supports renderers with colorInfo. Two samples have been updated to use this new functionality:

In addition to continuous color ramps, the esri/Color module was added at this release. It is a convenient wrapper around dojo/_base/Color and has all options supported by dojo/_base/Color.

Additional Changes and Enhancements

  • Edit tools: new textSymbolEditorHolder option to specify container for text symbol editing components.
  • All layers have a loadError property indicating if an error occurred while trying to retrieve layer metadata.
  • LocateButton.graphicsLayer option to specify the graphics layer where the associated graphic should be added.
  • Map has a new before-unload event.
  • All classes' on() method supports listening to multiple events with a single call. The first argument to on() should be a string with event names separated by commas. The second argument is still the function to run when an event happens.
  • dojoConfig.useDeferredInstrumentation is now true by default. This prints unhandled errors that occur somewhere in the lifecycle of an asynchronous task to the browser console instead of hiding them.
