This update is a bugfix release for Kolab 16, available for Red Hat Enterprise Linux 7, CentOS 7, Debian 8, Debian 9, Ubuntu 16.04 and Ubuntu 18.04, and for Plesk Premium Email version 17 on Red Hat Enterprise Linux 7, CentOS 7, Debian 8, Debian 9, Ubuntu 16.04 and Ubuntu 18.04.

The following issues are fixed and changed:
