Revit 2019 export to Artlanis

I have recently upgraded to Revit 2019 but unfortunately the 2019 plug in is not available on the Artlantis website. As i have upgraded my model files to the new version and Revit does not allow for saving backwards to older versions i can’t export to Artlantis. Just wondering when the Revit 2019 plug in will be available.
