+
+Scaffolder Field Extensions are here! This means you'll now have to change how the `ScaffolderPage` is wired up in your `app/src/App.tsx` to pass in the custom fields to the Scaffolder.
+
+You'll need to move this:
+
+```tsx
+<Route path="/create" element={<ScaffolderPage />} />
+```
+
+To this:
+
+```tsx
+import {
+  ScaffolderCustomFields,
+  RepoUrlPickerFieldExtension,
+  OwnerPickerFieldExtension,
+} from '@backstage/plugin-scaffolder';
+
+<Route path="/create" element={<ScaffolderPage />}>
+  <ScaffolderCustomFields>
+    <RepoUrlPickerFieldExtension />
+    <OwnerPickerFieldExtension />
+  </ScaffolderCustomFields>
+</Route>;
+```
+
+Failure to do this will result in no component being rendered for the custom field's like `OwnerPicker` and `RepoUrlPicker`.
+
+More documentation on how to write your own `FieldExtensions` to follow.
