With 17.2.6 we've added some new distributions to the build process:
- Fedora 17 and 28
- openSUSE 15
- Ubuntu 18.04
- Univention Corporate Server 4.3
Apart from the new distribution it is a maintenance and bugfix release. A director-crash after reloading with statistics collection enabled was fixed as well as predefined queries and a problem regarding file selection for restore.
