syncroton: 2.2.0??

[webmaster zigann.de]

Hi,

System: CentOS release 6.4 (Final) with Kolab 3.0, updated syncroton 
2.1-rc1.

With the original version, email where displayed as encrypted, but the 
calendar worked fine. So i updated to 2.1-rc1. Now email work fine. If i 
sync the calendar with my Samsung Galaxy S4 active (Android 4.2.2.), all 
entrys in calendar are displayed many times. The mobile phone take the 
whole bandwith and don't stop to syncronize until the battery is empty 
and the system breaks down.
I read something about "fread () in loop". May this could be the 
problem?  I substituted the two files mentioned in diff (Abstract.php 
and Decoder.php), but there is no effect. If i substitute the whole 
directory   /usr/share/kolab-syncroton/lib/, i can't authenticate 
against http://xxxxxxxxxxxxx.de/Microsoft-Server-ActiveSync anymore. 
Suppose, there is something to do im mysql?
So my question: is the error fixed in 2.2.0 and when it is, how can i 
update to 2.2.0 manually from git?

Sincerely

Torsten
