Hi Vakho, does this update need changes in atlas/athena? @corentin has an update waiting which will require changes in the offline software to incorporate (!866 (merged)). Can I bundle this update with that one into a single new tag?

Hi Attila, This update does not require any changes in Athena. Please feel free to bundle it with other updates, as needed. Thanks.
