I'm sorry it took so long, but good things take a while.

I am relieved the release is out because now that the problems with FreeBusy 
are solved, the 2.3 series offer the same functionality as 2.2.4  - plus much 
more of course.


The update to postfix 2.8 brings a lot of new features like postscreen and 
multi-instance support. However none of them is enabled by default and old 
configuration files continue to work. Have fun while exploring the new 
possibilities, we will make use of them in the next major release.


Most of the bugfixes affect Kolab_* packages such as Kolab_FreeBusy:

- apache-php: Security update fixing various CVEs
- Kolab_FreeBusy: Generating free/busy cache works again
- Kolab_Resource: Answers from resources no longer contain extra "\r\n\r\n"
- Kolab_Server: IMAP connection issues fixed
- Kolab_Storage: Webclient no longer hangs if freebusy triggering/retrieving
- kolab-webadmin: Listing of sub-folders and sub-calendars was fixed
- kolabd: Fixed an imap annotatoin so SyncML can sync contacts
- php: Security update fixing various CVEs
- postfix: Security update to 2.8.3. This also brings a lot of new features
- z-push: New version with many bug fixes, rebuilding with prefixes other than
  /kolab fixed.

For a complete list of changes please refer to


The upgrade form 2.3.1 is straight forward, there is nothing special you need
