+- Removed the additional `Navigator` in `StreamChat` widget.
+    It was added to make the app have the `StreamChat` widget as ancestor in every route.
+    Now the recommended way to add `StreamChat` to your app is using the `builder` property of your `MaterialApp` widget.
+    Otherwise you can use it in the usual way, but you need to add a `StreamChat` widget to every route of your app.
+    Read [this issue](https://github.com/GetStream/stream-chat-flutter/issues/47) for more information.
