@jpopesculian Thanks a lot! Quickly checked arrow=56, there seem to be no changes to the array types.

It seems you did not enable the option that I can push to your branch. Could you update the changelog Changes.md?

## 0.2.4

- Add `arrow=56` support.

Thanks [@jpopesculian](https://github.com/jpopesculian) for the
