Debian Squeeze. This marks a new era of not-so-obsolete software for the distribution's stable tree. The list includes GNOME 2.30, KDE 4.4.5, X.Org 7.5, OpenOffice.org 3.2.1 and Linux 2.6.32. Along with the current GNU/Linux release there is a "preview" of GNU/kFreeBSD which brings the FreeBSD kernel to the Debian userland stack. This preview release has great potential for the people looking to utilize BSD technology in the Debian environment. The new stable release also reaffirms the quality and stability of other distributions based off this tree such as Ubuntu 10.04 LTS.
Thank you, Debian!
