 ### Breaking Changes
 * To avoid dependency on `dart:io`
   - `AppConfiguration.httpClient` is now of type [`Client`](https://pub.dev/documentation/http/latest/http/Client-class.html) and
-  - `AppConfiguration.baseFilePath` is now of type `String`
+  - `AppConfiguration.baseFilePath` is now of type `String`.
+
+  Assuming you are configuring these today, migration is easy:
+  ```dart
+  import 'dart:io';
+  import 'package:realm_dart/realm.dart';
+
+  final client = HttpClient();
+  final dir = Directory.current;
+  final config = AppConfiguration(
+    'your-app-id',
+    httpClient: client,
+    baseFilePath: dir,
+  );
+  ```
+  becomes:
+  ```dart
+  import 'dart:io';
+  import 'package:realm_dart/realm.dart';
+  import 'package:http/io_client.dart';
+
+  final client = HttpClient();
+  final dir = Directory.current;
+  final config = AppConfiguration(
+    'your-app-id',
+    httpClient: IOClient(client),
+    baseFilePath: dir.path,
+  );
+  ```
   (Issue [#1374](https://github.com/realm/realm-dart/issues/1374))
 
 ### Enhancements
 * Report the originating error that caused a client reset to occur. (Core 14.9.0)
 * Allow the realm package, and code generated by realm_generator to be included when building 
   for web without breaking compilation. (Issue [#1374](https://github.com/realm/realm-dart/issues/1374),
-  PR [#1713](https://github.com/realm/realm-dart/pull/1713))
+  PR [#1713](https://github.com/realm/realm-dart/pull/1713)). This does **not** imply that realm works on web!
 
 ### Fixed
 * `Realm.writeAsync` did not handle async callbacks (`Future<T> Function()`) correctly. (Issue [#1667](https://github.com/realm/realm-dart/issues/1667))
