Yesterday, 14 February 2009, the Debian Project announced the official release of Debian GNU/Linux version 5.0 (codenamed “Lenny"). This comes after almost 2 years (22 months) from the previous stable release, “Etch” that was launched on 8 April 2007.
“This release includes numerous updated software packages, such as the K Desktop Environment 3.5.10 (KDE), an updated version of the GNOME desktop environment 2.22.2, the Xfce 4.4.2 desktop environment, LXDE 0.3.2.1, the GNUstep desktop 7.3, X.Org 7.3, OpenOffice.org 2.4.1, GIMP 2.4.7, Iceweasel 3.0.6 (an unbranded version of Mozilla Firefox), Icedove 126.96.36.199 (an unbranded version of Mozilla Thunderbird), PostgreSQL 8.3.6, MySQL 5.0.51a, GNU Compiler Collection 4.3.2, Linux kernel version 2.6.26, Apache 2.2.9, Samba 3.2.5, Python 2.5.2 and 2.4.6, Perl 5.10.0, PHP 5.2.6, Asterisk 188.8.131.52, Emacs 22, Inkscape 0.46, Nagios 3.06, Xen Hypervisor 3.2.1 (dom0 as well as domU support), OpenJDK 6b11, and more than 23,000 other ready-to-use software packages (built from over 12,000 source packages).”

“Upgrades to Debian GNU/Linux 5.0 from the previous release, Debian GNU/Linux 4.0 (codenamed “Etch”) are automatically handled by the aptitude package management tool for most configurations, and to a certain degree also by the apt-get package management tool. As always, Debian GNU/Linux systems can be upgraded painlessly, in place, without any forced downtime, but it is strongly recommended to read the release notes for possible issues, and for detailed instructions on installing and upgrading. The release notes will be further improved and translated to additional languages in the weeks after the release.”
Also my little post “HowTo upgrade from Debian Etch to Lenny” might be a useful read before upgrading.
