This time we had a short cycle and only a few updated packages, but I really 
wanted to get the 2.3.4 release out the door. It fixes not only the annoying 
build error that affected many people but also includes another fix for the 
Range header DoS vulnerability in the Apache webserver.


- apache: Security update to 2.2.21 fixing CVE-2011-3192


- imapd: The build error in imapd was fixed.
- kolab-webadmin: The ActiveSync configuration is back again.
- kolab-z-push: New version with bugfixes for various Nokia phones.
- z-push: New upstream version with many bugfixes.


- none

For a complete list of changes please refer to


The upgrade form 2.3.3 is straight forward, there is nothing special you need 
to care about.

If you are upgrading from 2.2.4, please follow the instructions to upgrade  
from 2.2.4 to 2.3.0 as outlined in 


Binary packages for Debian GNU/Linux 6.0 (Squeeze/stable) and 5.0 
(Lenny/oldstable) on x86 platforms can be found next to the sources.
