All reports of debian-watch-file-specifies-old-upstream-version for the archive. The extended description of this tag is:
The watch file specifies an upstream version number which matches the upstream portion of an old debian/changelog entry, and the current debian/changelog entry specifies a newer upstream version. The version number in the watch file is very likely to be incorrect and probably should be replaced with the current expected upstream version. Otherwise, DEHS and similar projects will think the package is out of date even when it may not be.
This tag has not been emitted in any package tested by Lintian.
