After tonights dinstall run, we will freeze 3.1r7 for sourcefull uploads, unless someone has a very good reason for another package inclusion for oldstable.
Adventureous admins (who have also a backup of their systems) might want to try to add olstable-proposed-updates to their /etc/apt/sources.list and try to upgrade. Please report any problems to the debian-release@lists.debian.org mailing list.
