[X2go-user] Debian repository - lastest stable release?

Hi x2go folks,

where can I find the latest stable x2go release in the 2xgo Debian repository?

http://www.x2go.org/index.php?id=7 claims the "most recenty release" Uthörn to be described as pool-lenny but also "maemo" as distributions "diablo" that should be added to apt's sources.list.

Looking at the repository itself we have diablo (no idea), heuler (somewhere refered to as prerelease), lenny, etch (both Debian releases) and ubuntu (a Debian based distribution)...

http://x2go.obviously-nice.de/deb/dists/

I'm really confused about releases, repositories and the naming scheme at all.

Thanks.

Michael
