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 watch file debian/watch, reading FTP directory ftp://ftp.netfilter.org/pub/ulogd/ failed: 500 Connection timed out
testing migration
This package will soon be part of the auto-openssl 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.
