Extensions 1.3.0

• The Extensions API library version 1.3 (tableau.extensions.1.3.0.js) is backward compatible with previous releases of the library.

• Now available: Extensions API type definitions and new TypeScript samples. The latest release provides the TypeScript type definitions so that you can author your extension using TypeScript. See Use TypeScript with the Extensions API and TypeScript Sample Extensions{:target="_blank"} on GitHub.

• New all-values-selected property for categorical filters (filter.isAllSelected). You can use this new property to determine when all values of categorical filters are selected. The isAllSelected property is a Boolean and returns True or False. Prior to this release, there was no way to tell if all values of categorical filters were selected. The filter.appliedValues method returns empty array when (All) is selected, so there is no way to use that method to determine if all values are selected or if no values are selected. The isAllSelected property is available starting with Tableau 2019.2 and the Extensions API library version 1.3 (tableau.extensions.1.3.0.js).
