+---
+
+The `SpawnedActorRef` TypeScript interface has been deprecated in favor of a unified `ActorRef` interface, which contains the following:
+
+```ts
+interface ActorRef<TEvent extends EventObject, TEmitted = any>
+  extends Subscribable<TEmitted> {
+  send: (event: TEvent) => void;
+  id: string;
+  subscribe(observer: Observer<T>): Subscription;
+  subscribe(
+    next: (value: T) => void,
+    error?: (error: any) => void,
+    complete?: () => void
+  ): Subscription;
+  getSnapshot: () => TEmitted | undefined;
+}
+```
+
+For simpler actor-ref-like objects, the `BaseActorRef<TEvent>` interface has been introduced.
+
+```ts
+interface BaseActorRef<TEvent extends EventObject> {
+  send: (event: TEvent) => void;
+}
+```
