Hi Hans,

the kolab package itself is largely unchanged because it is only used as 
a meta-package to pull in various dependencies - we've only introduced 
two new ones for Kolab 3.1, being chwala and iRony.

chwala and iRony (with WebDAV) both depend on a more recent version of 
libkolabxml, and libkolab than ships with Kolab 3.0, but not for the 
obvious reason (files) - a very mysterious chain of dependencies makes 
chwala and iRony depend on the latest roundcubemail, and the latest 
roundcubemail-plugins-kolab, versions of which cannot just be mixed and 
mangled (probably the cost of moving forward as fast).

That said, IMAP is still IMAP (replace /etc/imapd.annotations.conf with 
the new version for CardDAV / CalDAV compatibility), 
iRony/chwala/roundcube/syncroton from Kolab 3.1 can run on a different 
server (than MTA/LDAP, components that might have updates but do not 
require updates, and there's no further schema changes) and as such one 
could "stage" an upgrade...

That said, the upgrade path is far from described in detail. I'm working 
on both the actual documentation as well as the upgrade path / 
changelog[1].

This, and [2], might help you see why I can't really say all that much 
about a timeline.

Kind regards,

Jeroen van Meeuwen
