+**Note**: NativeScript 6 introduced two new tab navigation components, `<BottomNavigation>` and `<Tabs>`. These are meant to be new and better alternatives to the existing `<TabView>` component. Read [the announcement blog post here](https://www.nativescript.org/blog/tabs-and-bottomnavigation-nativescripts-two-new-components).
+
 `<TabView>` is a navigation component that shows content grouped into tabs and lets users switch between tabs.
