  • BUGFIX: Eliminated session object leakage from methods GetAppFields, GetSheets and their asynchronous equivalents.
  • DEPRECATED: Deprecated IApp extension methods for master object management. Use engine endpoints for these operations.
  • DEPRECATED: Deprecated class Qlik.Sense.Client.GeoField and associated interface IGeoField. Use AppField and IAppField directly for this functionality.

  • DEPRECATED: Deprecated storytelling related functionality. Use GenericObject and AbstractStructure to interact with this client functionality.
  • DEPRECATED: Deprecated snapshot related functionality. Use GenericBookmark and AbstractStructure to interact with this client functionality.

v15.0.6

  • BUG FIX: The LocationExtension methods Hub, App, ActiveApp and corresponding async methods now close the websocket connection if an error occurs. Previously the SDK could leak connections if the websocket was successfully established but an error occurred after that. A typical example would be that a call to OpenApp timed out when calling LocationExtension.App

v15.0.5

  • BUG FIX: Removed fixed 5 second timeout on websocket opening. The RpcConnection.Timeout property now affects this operation. This behavior is identical to the timeout behavior used for the .NET Framework version of the SDK for release v14.1.0 and earlier.
  • BUG FIX: Fixed issue with websocket connections sometimes being left open when the websocket connection succeeds, but the method called to open the connection times out.

v15.0.4

  • SCHEMA: API endpoints generated based on engine version 12.674.1 (Qlik Sense June 2020)

  • DEPRECATED: Deprecated promoted layout properties in the Client namespace. Access values through the Properties and Layout properties instead.
  • REMOVED: Removed the class Qlik.Sense.Client.DataContainer as well as client object specific methods in the Sheet class. Deprecated since v13.16.0.
