+- **Breaking Change**: Moved annotations to single location in
+  `dart:_js_annotations`. This makes it easier to avoid collisions with
+  `dart:js_interop`'s `@JS`, as you will now see a static error instead of it
+  resolving in favor of the package definition. However, since this may result
+  in breakages in previously working code, this is treated as a breaking change.
