   ```
 
+- Starting from language version 3.9 the `flutter` constraint upper bound is now
+  respected in your root package. For example:
+
+```yaml
+name: my_app
+environment:
+  sdk: ^3.9.0
+  flutter: 3.33.0
+```
+
+Will fail `dart pub get` if invoked with any Flutter different from 3.33.0.
+
+The upper bound of the flutter constraint is still ignored in packages you use
+as dependencies.
+See https://github.com/flutter/flutter/issues/95472 for details.
