Update: kolab-webadmin 3.2.12 (Updated)

We’re pleased to announce a further update for the kolab-webadmin packages, version 3.2.12.

This update is a bugfix release for Kolab 16, available for CentOS 7, Debian 8, Debian 9, Red Hat Enterprise Linux 7 and Ubuntu 16.04.

This regression was fast eliminated, and a new package created and released. If you update at this time, there is no such issue present.

We ask you to please accept our apologies for the inconvenience this has caused.
