Minor Changes

• #4832 148d8fcef Thanks @cevr! - fromPromise now passes a signal into its creator function.

  const logic = fromPromise(({ signal }) =>
    fetch('https://api.example.com', { signal })
  );

  This will be called whenever the state transitions before the promise is resolved. This is useful for cancelling the promise if the state changes.

Patch Changes

• #4876 3f6a73b56 Thanks @davidkpiano! - XState will now warn when calling built-in actions like assign, sendTo, raise, emit, etc. directly inside of a custom action. See https://stately.ai/docs/actions#built-in-actions for more details.

  const machine = createMachine({
    entry: () => {
      // Will warn:
      // "Custom actions should not call \`assign()\` directly, as it is not imperative. See https://stately.ai/docs/actions#built-in-actions for more details."
      assign({
        // ...
      });
    }
  });
