Just a reminder, we should update the authors list before the final release. We don't do it now because we want to have an updated translators list which we will get from transifex when needed.
I can write a small script that dumps the users-per language team from the tx installation. We also shouldn't forget the bump the xfce version in libxfce4util.
Uh did is automated now, tx submits a new list in xfce-utils every sunday at 0:00.
