 - **TextBox**, **MaskedTextBox**, **TextArea** - `Label` parameter is removed. In 3.2.0 release we will release standalone Floating Label component. In the meantime, you can use the following [KB that shows how to add the label]({%slug inputs-kb-floating-label %}).
 - **TileLayout** - introduced optional `Id` attribute for the `TileLayoutItem`. The `OnResize` event handler will receive argument of type `TileLayoutResizeEventArgs`. The `OnReorder` event handler will receive argument of type `TileLayoutReorderEventArgs`. Both event arguments will point to the tile item (`args.Id`) and define if the component should re-render after the event (`args.ShouldRender`).
