 ### New Features
+- Added `IgxPivotGrid` component(Preview)
+    - The igxPivotGrid is a data presentation control for displaying data in a pivot table. It enables users to perform complex analysis on the supplied data. Main purpose is to transform and display a flat array of data into a complex grouped structure with aggregated values based on the main 3 dimensions: rows, columns and values, which the user may specify depending on his/her business needs. The whole pivot grid configuration is set through `IPivotConfiguration` interface.
+
+    ```html
+    <igx-pivot-grid [data]="origData" [pivotConfiguration]="pivotConfigHierarchy">
+    </igx-pivot-grid>
+    ```
