Versions 2.2 of both the ArcGIS API for Flex and ArcGIS Viewer for Flex are now available.
We’ve added a few things and fixed a few things. The key aspects of the 2.2 release are:
- Support for ArcGIS.com Web Maps in both API and Viewer.
- New Legend Component in the API and Legend Widget in the Viewer.
- Undo/Redo capabilities while editing.
- User experience enhancements to six Flex Viewer widgets: Draw, Data Extract, Query, Search, Static Image, and Time Slider.
To begin using the API, download the new Flex API Library and recompile your applications.
The 2.2 version is fully backward compatible with your 2.1 and 2.0 applications.
To begin using the new viewer, download the compiled Flex Viewer or, if you are a Flex developer,
get the source code.
The 2.2 viewer is backward compatible with our 2.1 widgets.
