This 1st release candidate (and the actual release) ship 3 Desktop Environments, KDE SC, in 32-bit version. This flavour does not fit on a CD anymore, so it made no sense to go for lite and full versions.
The released images represent a snapshot of Debian Sid from 2011-12-21, enriched with a few useful packages and scripts, an installer and our own, patched version of kernel 3.1-5 and xserver 1.11.2.902-1.
