Debian GNU/Linux 4.0 "Etch" is the 9th and most recent stable release of Debian GNU/Linux. It is supported until one year after the next release, which is planned for September 2008. Etch can be ran with either KDE, GNOME, or Xfce as the default GUI. It can also be ran with no GUI whatsoever, and can be used as a server. Major features that were added to Etch are the ability to install on the amd64 architecture, transition to X.Org and udev, as well as a graphical installer.
