Thank you for updating the package to upstream v2.3 and uploading it! I have released further changes upstream and updated the package to the new version, 2.3.1. So I hope that's good to upload as well.
Will do. However, (basic)tests seem to be failing on arm64.
It seems to be related to cfitsio issues with int being interpreted differently.
Could you please take in a look so the new release migrates to testing?
