Mandrake 9.1 is a major release because it provides very visible changes. We have worked much on improving the ergonomics and the look of Mandrake. So users are going to find a new installation procedure which is much more simple than the previous one. It is mostly automated and needs very little information from the user. Anyway, we wanted to keep intact the power of the previous installer so we included several 'expert buttons' everywhere, which lead to more sophisticated configuration areas.
