The package has a debian/watch file, but the last attempt
to use it for checking for newer upstream versions failed with
an error:
In debian/watch no matching files for watch line ftp://dicom.offis.de/pub/dicom/offis/software/dscope/dscope([\d]+)/dsgui(\d)(\d)(\d)\.zip
testing migration
This package will soon be part of the auto-dcmtk transition. You might want to ensure that your package is ready for it.
You can probably find supplementary information in the
debian-release
archives or in the corresponding
release.debian.org
bug.
