XFree86 upgrade

[gustavo halperin <ggusti@gmail.com>]

Hello  List

There are any reason because of what the last 
Debian-package-XFree-version is
the 4.3.x and not the 4.4.x or the new one 4.5.0 ?
And is risky to upgrade to 4.5 and which are the correct way to do it 
in Debian ?

 Thank you very much
