Release Notes: This is the second bugfix release for the Kolab 2.3 series. Most fixes are in the Free/Busy stack and the automatic resource handling. 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 to allow smooth upgrades. The ActiveSync configuration introduced in Kolab 2.3.1 has slightly been reworked and Z-push 1.5.3 makes synchronization with mobile devices more reliable.
Release Notes: The highlights of this release are a new file cloud storage feature and CalDAV/CardDAV support for a great variety of devices, platforms, and clients. There are also improvements and automations for multi-domain hosted environments. Shared folders can now not only be created with the kolab commandline utility, but also in the Web administration interface.
Release Notes: The most notable new features are CalDAV and CardDAV support. There is also integration with file storage in the Web client. It serves files through WebDAV.
Release Notes: Compared to the old 2.3.4 stable release, this version features a new modern Web client that integrates Roundcube instead of Horde. It integrates a lot better into existing user directory setups. Security as well as scalability has been greatly improved. It is now possible to scale all functional components of Kolab separately. There is a new unified command line utility for administrative tasks.
Release Notes: This release mainly fixes reported bugs and stabilizes the Debian packages further. Users of earlier 3.x releases can simply upgrade to the new packages, since Kolab is now on a rolling release. Great progress has been made packaging Kolab for OpenSUSE 12.2.
Release Notes: The highlights of this release are working Debian packages, object types editing in the Web admin, and many bugfixes.
