 ### Tableau Dashboard Extensions API version 1.4
 *May 2020*
 
+
 * Tableau Dashboard Extensions API library: `tableau.extensions.1.4.0.js` <br>(download or clone the Extensions API repository on [GitHub](https://github.com/tableau/extensions-api){:target="_blank"}). <br/>
 
+About this release:
+
 * To support the logical and physical tables introduced in Tableau 2020.2, the Tableau Dashboard Extensions API (version 1.4) provides new APIs and data structures. Use these new methods to get the underlying data from data sources and worksheets. The new methods replace `getUnderlyingDataAsync`. Starting in Tableau 2020.2, a data source could have multiple logical tables, and logical tables can contain one or more physical tables. If you have an existing extension that uses one of the deprecated methods to get underlying data, the method call could fail if the data source contains more than one logical table. You should update your extensions to use these new methods. The new methods are backward compatible with previous versions of Tableau.

-* `DataValue` now has a `nativeValue` member. This member represents the raw native value as a JavaScript type, which is one of string, number, boolean, or Date object. Note that special values are returned as null. The `nativeValue` helps simplify error checking as all values will either be their native type value or null. The `nativeValue` exists for *ALL* `DataValue` objects, including those returned from parameters, filters, selections, and underlying or summary data.

+Bugs fixed in this release:
+
+* Previously, when a user was viewing a dashboard on Tableau Server or Tableau Online and an extension API call was denied because the user did not have permission for that functionality, the dashboard would be refreshed and extension reloaded. This caused the user to potentially lose state. Now the permission will be properly denied, but the dashboard and extension will not reload.
+
+* Range filters now work correctly when the minimum or maximum values are equal to zero (0). Previously, calls to the `applyRangeFilterAsync()` method would ignore the `RangeFilterOptions` if the `min` or `max` properties were equal to zero (0).
+
+* The `isVisible` attribute for dashboard zones is now set properly to true or false when the extension is initialized.
+
+* The `setZoneVisibilityAsync()` method now supports ES6 map objects for the `zoneVisibilityMap` parameter.

 * Fixed in the Extensions API library 1.2, the type of `DataValue.value` is now the raw native value as a JavaScript type, rather than always defaulting to **String**. A `DataValue.value` can be one of the following JavaScript types: **String**, **Number**, **Boolean**, or **Date**.
  A `DataValue` is returned as a property of a `DataTable` in methods, such as `getSummaryDataAsync()` or `getUnderlyingDataAsync()`.  Note that special values, regardless of type, are always returned as **String** values surrounded by percent signs, such as `%null%`, or `%no-access%`. <br/>**Important!** If your code depended on the type of `DataValue.value` always being a **String**, that code will now break with this fix.
