Based on Debian “Wheezy”, Knoppix 7.2 packs quite a few new features including newer desktop packages from Debian/testing and Debian/unstable Jessie. The latest version uses Linux 3.9 kernel and xorg 7.7 and comes loaded with LibreOffice 4.0, GIMP 2.8, Chromium 27 (and Firefox/Iceweasel 21), Wine 1.5, Virtualbox version 4.2.10 and uses LXDE by default.
Users who still want to go for KDE or GNOME, version 4.8.4 and 3.4.2 of the respective desktops are available from the Knoppix DVD. Version 7.2 also comes with support for UEFI booting and comes with ADRIANE – a talking menu system, which is supposed to make computer tasks and internet access easier for beginners.
The release announcement on Knopper.net states that a public release of the version 7.1 was planned but didn’t happen as new things came in and there were lot many updates pending including two kernel versions with improved hardware support and EFI edition of the syslinux bootloader.
