     - **Breaking Changes** - The `igx-action-icon` has been renamed to `igx-navbar-action`. It should get renamed in your components via `ng update`;
 - `igxGrid`
     - Added `onScroll` event, which is emitted when the grid is scrolled vertically or horizontally.
+    - Each grid now expose a default handling for boolean column types. The column will display `check` or `close` icon, instead of true/false by default. 
 - `igxTreeGrid`
     - Removed `onDataPreLoad` event as it is specific for remote virtualization implementation, which is not supported for the `igxTreeGrid`. A more generic `onScroll` event is exposed and can be used instead.
 - `IgxTimePicker`
