The Debian project has updated the stable distribution Debian GNU/Linux 3.1 (codename sarge). This update mainly adds security updates to the stable release, along with a few corrections to serious problems. Those who frequently update from security.debian.org won't have to update many packages and most updates from security.debian.org are included in this update.
Please note that this update does not constitute a new version of Debian GNU/Linux 3.1 but only updates some of the packages included. There is no need to throw away 3.1 CDs. Instead you only need to update against ftp.debian.org or a mirror after an installation, in order to incorporate those changes. New CD and DVD images are being built right now and will be available soon at the regular locations.
