+The `createStoreWithProducer(…)` function now uses the new configuration API:
+
+```ts
+import { createStoreWithProducer } from '@xstate/store';
+// DEPRECATED API
+// const store = createStoreWithProducer(
+//   producer,
+//   {
+//     count: 0
+//   },
+//   {
+//     inc: (context, event) => {
+//       context.count++;
+//     }
+//   }
+// );
+
+const store = createStoreWithProducer(producer, {
+  context: {
+    count: 0
+  },
+  on: {
+    inc: (context, event) => {
+      context.count++;
+    }
+  }
+});
