The long awaited final version of Kolab 3 has been made available. Compared to the old 2.3.4 stable release, this brand new version of Kolab features a new modern webclient 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. Also, there is a new unified command line utility for administrative tasks.
Kolab 3 dropped OpenPKG and can now be installed with native packages on Redhat Enterprise Linux, CentOS and Debian. OpenSUSE packages are also available, but still experimental and packages for Mageia are a work in progress. With native packages, Kolab is now seamlessly integrated into the rest of the system, can easily be upgraded and allows for a rolling release. This keeps updates fast, simple and makes sure everybody can benefit from latest fixes and new features without big complicated upgrade procedures. From Kolab 3.0 onwards, we are aiming for a six months release cycle, so you can expect Kolab 3.1 in Summer. Development is already in full swing.
