+The `shallowEqual` comparator has been added for selector comparison:
+
+```tsx
+import { shallowEqual } from '@xstate/store';
+import { useSelector } from '@xstate/store/react';
+
+import { store } from './store';
+
+function MyComponent() {
+  const state = useSelector(
+    store,
+    (s) => {
+      return s.items.filter(/* ... */);
+    },
+    shallowEqual
+  );
+
+  // ...
+}
+```
