+- Added `IgxSimpleComboComponent`
+    - The `igx-simple-combo` which is a modification of the `igx-combo` component that allows single selection and has the appropriate UI and behavior for that. It inherits most of the `igx-combo`'s API.
+    - Allows the selection of single items in a filterable list.
+    - Supports custom values, keyboard navigation, validation, customized positioning of the item list via overlay settings.
+    - Example:
+    ```html
+    <igx-simple-combo [(ngModel)]="item" [allowCustomValues]="true" [placeholder]="'Search'" [data]="items">
+        <label igxLabel>Items</label>
+        <igx-hint>Please select an item from the dropdown list.</igx-hint>
+    </igx-simple-combo>

 - `IgxToastComponent`
-    - **Deprecated** - The `position` input property has been deprecated. Use `positionSettings` input instead.
