Thanks to Jens Larsen Intelligent Surface comes now with a danish translation with todays 5.0.4 release.
It also fixes a SubQuestion bug in single level hierarchies on Premium Versions.
A small update on OTRS6: All 5.x Version of Intelligent are incompatible with it as the DB structure and API were massively changed. Intelligent Surface 6.0 is scheduled to arrive in January 2018.
A Lite Version is also available at the download section.
