+
+The `waitFor(...)` helper function, which asynchronously _waits_ for an actor's emitted value to satisfy a `predicate` before a `timeout`, is now available.
+
+Example usage:
+
+```js
+import { waitFor } from 'xstate/lib/waitFor';
+
+// ...
+const loginService = interpret(loginMachine).start();
+
+const loggedInState = await waitFor(loginService, (state) =>
+  state.hasTag('loggedIn')
+);
+
+loggedInState.hasTag('loggedIn'); // true
+```
