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.
