The other answers aren't quite right, but combining them put me on the right track.
/etc/update-manager/release-upgrades controls what updates you'll be notified about. /usr/lib/update-manager/release-upgrade-motd generates the "update available" message. The problem is that release-upgrade-motd caches the message, which means that once it's been generated, changing /etc/update-manager/release-upgrades doesn't get rid of the message.
So the answer is:
Tell Update Manager what releases you want to be notified about.
sudo rm /var/lib/update-notifier/release-upgrade-availableto get rid of the cached message.
Note: For version 13.04 (and later), the path has changed. So point 2. to get rid of the cached message is now:
sudo rm /var/lib/ubuntu-release-upgrader/release-upgrade-available
