+    - **Breaking Change** - Hierarchical grid children no longer use the same `IgxTransactionService` instance and transaction handling should be modified to address each grid's transactions separately.
     - **Behavioral Change** - Pinning columns is no longer automatically prevented when the pinning area would exceed the size of the grid.
     - `igxGridState` directive added to make it easy for developers to save and restore the grid state. The directive exposes the `getState` and `setState` methods to save/restore the state and an `options` input property to exclude features.

     - `tickLabelsOrientation` input was added. Allows you to change the rotation of all tick labels from horizontal to vertical(toptobottom, bottomtotop).
     - `igxSliderTickLabel` directive has been introduced. Allows you to set a custom template for all tick labels.
     - `isContinuous` - input has been deleted. The option is not supported anymore.
+    - `onValueChanged` - new output has been exposed. This event is emitted at the end of every slide interaction.

 - `IgxSelect`: 
     - adding `IgxSelectHeaderDirective` and `IgxSelectFooterDirective`. These can be used to provide a custom header, respectively footer templates for the `igxSelect` drop-down list. If there are no templates marked with these directives - no default templates will be used so the drop-down list will not have header nor footer.
 
+- `IgxDropDown`:
+    - `clearSelection` method is added, which can be used to deselect the selected dropdown item
+
+- `IgxCircularProgressBar`:
+    - added `IgxProgressBarGradientDirective` to allow providing custom circular progress SVG gradients. Providing a custom gradient via a template is as easy as writing:
+    ```html
+    <igx-circular-bar [value]="77">
+        <ng-template igxProgressBarGradient let-id>
+            <svg:linearGradient [id]="id" gradientTransform="rotate(90)">

+    </igx-circular-bar>
+    ```
+    - changed the `igx-progress-circular-theme` to accept a list of 2 colors for the `$progress-circle-color` argument, making it easier to modify the default gradient:
