Is there a safe way of upgrading to Xfce4.8 on stable?

[AG <computing.account@googlemail.com>]

Hey list

On stable, I am currently running Xfce4.6.  I notice that in the sid 
repos, Xfce4.8 is available.  Is there a safe way of upgrading to 4.8 in 
a manner that will not break my system, or is it really only a matter of 
waiting for Xfce4.8 to make its way through the repos to stable?

Thanks.
