-### New Features
-- `igxGrid`, `igxHierarchicalGrid`, `igxTreeGrid`
     - Added two public methods that spawn the add row UI for an arbitrary record in the current data view. One that accepts a rowID to use as the row the UI spawns under and the other accepting an index that has a distinct implementation for `IgxTreeGrid`. Please, refer to the official documentation for more information: [Grid Row Adding](https://www.infragistics.com/products/ignite-ui-angular/angular/components/grid/row-adding) and [Tree Grid Row Adding](https://www.infragistics.com/products/ignite-ui-angular/angular/components/treegrid/row-adding).
 
         _Note:_ That the new record is still added at the end of the data view, after the end-user submits it.

     - The column formatter callback signature now accepts the row data as an additional argument:
-    ```typescript formatter(value: any, rowData?: any)```
-    The `rowData` argument may be `undefined` in remote scenarios/applying the callback on filtering labels
-    so make sure to check its availability.

 - `IgxExcelExporterService`
     - Added support for freezing column headers in **Excel**. By default, the column headers would not be frozen but this behavior can be controlled by the `freezeHeaders` option of the IgxExcelExporterOptions object.
