Zustand 4.x and React 19

[moklick]

Hey!

Thanks for this superb library @dai-shi 🙏

Currently we are facing an issue with React19. React Flow still uses Zustand4 because we would like to support React17 a little longer. Now it's not possible for us to support React19, because the latest Zustand4 release uses an old use-sync-external-store version. Would it be possible to do another Zustand4 release with the latest use-sync-external-store as a dependency? That way we could support React 19 with Zustand4.

It is okay to add ^ for "use-sync-external-store": "1.2.2"?

Thanks for your quick answer! I think that should do it. When user re-install, the latest use-sync-external-store version 1.4.0 should be used and that one supports React 19.

wow! that was super fast :) I can confirm that Zustand 4.5.6 now works with React 19.
