[Kroupware] Updating Kolab

[Carsten Schurig]

Hi,

I've just seen that there's a ZfOS version of Kolab is available more 
recent than the one I've installed. I'm using kolab-20040217-2.0.0 
currently (more or less; I had to update imap) and the most recent 
version on ZfOS.org is kolab-20040503-2.1.0.

As there's no README provided, I have some questions:

- What are the most prominent changes?
- How do I update my installtion?

Thanks,
	Carsten
