There is a new gpg key used to sign the Release file, you here it is:

The repository url changed too, so here is the new lines to be added to /etc/apt/sources.list:
deb http://debian.corsac.net/ unstable/
deb-src http://debian.corsac.net/ unstable/
There, you will found ppc, i386 and am64 packages for Xfce 4.4rc1 (4.3.99.1). As always, those packages should be fine (I currently use them) and are to-be-uploaded ones. But they may be completely broken for some days, when we work on them, so don't rely on them for stable work.
Be sure to report any bug found (upgrade problems or new bugs) to Debian Xfce Maintainers or pass to our irc channel (#debian-xfce@irc.freenode.net).
