All reports of newer-debconf-templates for the archive. The extended description of this tag is:
debconf-updatepo has not been run since the last change to your debconf templates.
You should run debconf-updatepo whenever debconf templates files are changed so that translators can be warned that their files are outdated.
This can be ensured by running debconf-updatepo in the 'clean' target of debian/rules. PO files will then always be up-to-date when building the source package.
This tag has not been emitted in any package tested by Lintian.
