ArcGIS API 3.6 for Flex
The following functionality, enhancements, changes, and bug fixes are new at version 3.6 which was released in December 2013:
- NIM092242 - Can now specify hyperlinks for fields with URLs in the 'Show related records' pop-up.

- Added GeoEnrichment capabilities - Using GeoEnrichment, you can get information about the people, places, and businesses in a specific area or within a certain distance or drive time from a location. You can also use the GeoEnrichment service to obtain additional geographic context (for example, the ZIP Code of a location) and geographic boundaries (for example, the geometry for a drive-time service area). Read more at here and the API Reference for GeoEnrichmentTask and Infographic. See the GeoEnrichment samples.
- IdentityManager support for OAuth when accessing ArcGIS Online for Organizations. One new class, OAuthInfo, three new methods (findOAuthInfo(), registerOAuthInfos() and signOut() ) and four new IdentityManager events. (showOAuthLauncher, showOAuthWebView, signIn and signOut).

The following functionality, enhancements, changes, and bug fixes are new at version 3.1 which was released in December 2012:
- New AttributeTable component - an interactive editable data table for feature layers and tables. Aside from providing a tabular display of the layer's data, graphics can be selected, deselected, and zoomed to by interacting with the AttributeTable. If the layer is editable, the feature attributes will be editable and it will support domains and subtypes as defined by the Feature Service. New related classes: AttributeTableColumn, AttributeTableEvent and AttributeTableSkin. See the AttributeTable sample.

Changes to be aware of when migrating from 3.0 to 3.1
- The default AttributeInspector.singleToMultilineThreshold property has increased from 40 to 50 to better align with the default length (50) for strings fields created in ArcMap.
- Mobile: the default panEasingFactor has changed for mobile applications to give a better "feel" when panning or "throwing" the map.
- There is a known-limit when working with pop-up windows in mobile applications created with version 3.1. If doing so, please note that you will need to either:
- add both mx.swc and sparkskins.swc to your project, or
- update the PopUpRendererSkin class and remove references to the RelationshipInspector component.
- The ArcGISTiledMapServiceLayer.url defaults to .
- Property changes:
- The copyright property has moved to Layer, instead of being on some of the *Layer(s) which now inherits it from Layer.copyright instead. This affects ArcGISDynamicMapServiceLayer.copyright, ArcGISImageServiceLayer.copyright, ArcGISTiledMapServiceLayer.copyright and WMTSLayer.copyright.
- The ownershipBasedAccessControlForFeatures property on FeatureLayerDetails is now inherited from LayerDetails.ownershipBasedAccessControlForFeatures.
- The ownershipBasedAccessControlForFeatures property on FeatureTableDetails is now inherited from TableDetails.ownershipBasedAccessControlForFeatures.

- On mobile devices InfoWindow was flickering when panning.
- The SignInWindow is more mobile and tablet friendly. [NIM085020]
ArcGIS API 3.0 (final) for Flex
The following functionality, enhancements, changes, and bug fixes are new at version 3.0 which was released in June 2012:
- Connect to ArcGIS Online and Portal for ArcGIS by taking advantage of the ArcGIS Portal API.
- Requires Adobe Flex 4.6 SDK or higher, which in turn requires at least Flash Player 11.1.
- Since 2.5, 63 new classes, 138 properties on existing classes, and 57 methods on existing classes have been added to support new API functionality and support for ArcGIS 10.1 functionality, ArcGIS Online, and Portal for ArcGIS.
- Using panEasingFactor in mobile samples for better panning on mobile devices.
- The webmap package has been renamed to portal and includes new class for connecting to ArcGIS Online and Portal for ArcGIS.
- The arcgisSharingURL property in WebMapUtil has been renamed to portalURL.
- The default value for Map.openHandCursorVisible has changed from true to false.
- On the GeometryServicethe input parameter for the project() method is now projectParameters instead of geometries. This also allows for specifying datum transformations [requires ArcGIS Server 10.1].
- On the Locator the input parameter for the addressToLocation() method is now addressToLocationParameters instead of address, outfields. This also adds support for batch geocoding and searching within an extent [requires ArcGIS Server 10.1].
- The layerDefinitions property on ArcGISDynamicMapServiceLayer, FindParameters and IdentifyParameters can now take LayerDefinition in addition to a string. When using MXML, only LayerDefinition is allowed. When using ActionScript, both ways are allowed.
- The default value for the UniqueValueRenderer.fieldDelimiter (formerly UniqueValueRenderer.attributeDelimiter) has changed from "" (empty string) to "," (comma) and "" is no longer a valid value.
- The TextSymbol constructor now takes an alpha value as its 4th parameter. If you were using the TextSymbol constructor with more than three parameters, you need to adjust accordingly.

Numerous bug fixes were made for 3.0 final.
ArcGIS API 3.0 (prerelease) for Flex
The following functionality, enhancements, changes, and bug fixes are new at version 3.0 prerelease:
- Requires Adobe Flex 4.5 SDK or higher, which in turn requires at least Flash Player 10.2.
- Support for new ArcGIS for Server 10.1 capabilities
- Change renderers or layer order in map services (dynamic layers).
- Add layers on the fly in map services (dynamic workspaces).
- Generate data classifications on the server for layers in map services.

- KML layer supports refresh and httpquery.
- Better locale support for VETiledLayer (Bing Maps).
- The toJSON() and fromJSON() methods work with objects, not strings.
- The Domain class is now an interface and has been renamed to IDomain.
- The JSON class has been renamed JSONUtil, which is the same naming convention as for all the other classes in the utils package, and it also prevents collision with the JSON class added in Adobe Flash Player 11.
- The Renderer class implements the new IRenderer interface.
- The id property in LayerInfo has been renamed to layerId.
- The attribute, attribute2, attribute3, and attributeDelimiter properties that were deprecated at 2.5 have been removed at 3.0. Use field, field2, field3, and fieldDelimiter instead.

- Removed the following deprecated methods: FeatureSet.convertToJSON(), FeatureSet.convertFromJSON(), and NavigationToolzoomToFullExtent().
- Removed the following deprecated event: AttachmentInspector result event.
- Removed the unit property from the Map and Layer classes. This is now automatically inferred from the spatial reference.
- The default value for the visibleLayers property on ArcGISDynamicMapServiceLayer and ArcIMSMapServiceLayer have changed to null. Previously they defaulted to the visible layers as defined by the default visibility in LayerInfo.
- The ClassBreaksRenderer has a new property, isMaxInclusive, that defaults to true to align with ArcGIS for Server, which is always inclusive. Previously, the behavior was to not be inclusive.
If you're upgrading an application from version 2.5 to 3.x, be sure to read Migrating from 2.5 to 3.x.
For most functionality (for example, basic mapping and query), ArcGIS Server 9.3 or later is more than adequate. For editing, time-aware layers, closest facility, and service area, the ArcGIS API for Flex 2.0 (or later) and ArcGIS Server 10.0 (or later) are required. For PrintTask, dynamic layers, and dynamic workspaces, the ArcGIS API 3.0 for Flex (or later) and ArcGIS for Server 10.1 (or later) are required. See system requirements for more details.
