Minor Changes

• #3190 fbf5ca0ad Thanks @​davidkpiano! - 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:

  import { waitFor } from 'xstate/lib/waitFor';
  // ...
  const loginService = interpret(loginMachine).start();
  const loggedInState = await waitFor(loginService, state =>
  state.hasTag('loggedIn')
  );
  loggedInState.hasTag('loggedIn'); // true

• #3200 56c0a36 Thanks @​Andarist! - Subscribing to a stopped interpreter will now always immediately emit its state and call a completion callback.

Patch Changes

• #3166 be4c5c74d Thanks @​Andarist! - Fixed an issue with state.tags not having correct values when resolving micro transitions (taken in response to raised events). This was creating issues when checking tags in guards.

• #3171 14f8b4785 Thanks @​Andarist! - Fixed an issue with onDone on parallel states not being "called" correctly when a parallel state had a history state defined directly on it.

• #2939 360e85462 Thanks @​Andarist! - Fixed issues with not disposing some cached internal values when stopping interpreters, which could have led to issues when starting such an interpreter again.

• #3153 b36ef9dda Thanks @​Andarist! - Made type displays (like in the IDE tooltips etc) more readable by using a type interface for the internal ResolveTypegenMeta type.
