FSLabs took to the forums to announce an update for their FSLabs A32X family aircraft. The latest version v2.0.2.440 makes the aircraft fully compatible with the latest hotfix for Prepar3D v4.5. There are no other changes in this update. The developer does mention explicitly that this update does not make the aircraft compatible with Prepar3D v5.
The update is available on the download page.
