Minor Changes

• #4936 c58b36dc3 Thanks @davidkpiano! - Inspecting an actor system via actor.system.inspect(ev => …) now accepts a function or observer, and returns a subscription:

  const actor = createActor(someMachine);
  
  const sub = actor.system.inspect((inspectionEvent) => {
    console.log(inspectionEvent);
  });
  
  // Inspection events will be logged
  actor.start();
  actor.send({ type: 'anEvent' });
  
  // ...
  
  sub.unsubscribe();
  
  // Will no longer log inspection events
  actor.send({ type: 'someEvent' });

• #4942 9caaa1f70 Thanks @boneskull! - DoneActorEvent and ErrorActorEvent now contain property actorId, which refers to the ID of the actor the event refers to.

• #4935 2ac08b700 Thanks @davidkpiano! - All actor logic creators now support emitting events:

  Promise actors

  const logic = fromPromise(async ({ emit }) => {
    // ...
    emit({
      type: 'emitted',
      msg: 'hello'
    });
    // ...
  });

  Transition actors

  const logic = fromTransition((state, event, { emit }) => {
    // ...
    emit({
      type: 'emitted',
      msg: 'hello'
    });
    // ...
    return state;
  }, {});

  Observable actors

  const logic = fromObservable(({ emit }) => {
    // ...
  
    emit({
      type: 'emitted',
      msg: 'hello'
    });
  
    // ...
  });

  Callback actors

  const logic = fromCallback(({ emit }) => {
    // ...
    emit({
      type: 'emitted',
      msg: 'hello'
    });
    // ...
  });
