external horde

[Alar Sing]

Hello,

I readed on kolab wiki 
http://wiki.kolab.org/index.php/Kolab2_Installation_-_Horde that I can 
use horde on external apache server. There was installation script 
http://kolab.org/cgi-bin/viewcvs-kolab.cgi/*checkout*/server/horde/external-horde.sh
  this installs horde3.2-rc1 is this the newst version of horde that is 
supported with kolab 2.2?
Or there is now patching involved with horde3.2 stable versions?
