Minor Changes

• 6596d0ba #1622 Thanks @davidkpiano! - Spawned/invoked actors and interpreters are now typed as extending ActorRef (e.g., SpawnedActorRef) rather than Actor or Interpreter. This unification of types should make it more straightforward to provide actor types:

  import {
  - Actor
  + ActorRef
  } from 'xstate';
  
  // ...
  
  interface SomeContext {
  - server?: Actor;
  + server?: ActorRef<ServerEvent>;
  }

  It's also easier to specify the type of a spawned/invoked machine with ActorRefFrom:

  import {
    createMachine,
  - Actor
  + ActorRefFrom
  } from 'xstate';
  
  const serverMachine = createMachine<ServerContext, ServerEvent>({
    // ...
  });
  
  interface SomeContext {
  - server?: Actor; // difficult to type
  + server?: ActorRefFrom<typeof serverMachine>;
  }

Patch Changes

• 75a91b07 #1692 Thanks @Andarist! - Fixed an issue with history state entering a wrong state if the most recent visit in its parent has been caused by a transient transition.
