Upgrading Roundcube Version Lion Server

[PaSav]

How can i upgrade the roundcube version that comes with Lion Server. It is basic version 0.6 but with some Apple Tweeks i guess.
It is also handy to know with roundcube 0.8 around the corner.

I don't know how the Apple Tweeks would respond to an upgrade but you should be able to follow the standard upgrade instructions. http://trac.roundcube.net/wiki/Howto_Upgrade
