As always in the patch there are bug fixes and no new features:

The following problems, among others, were resolved:

- The calculation is not possible on some very old systems; DIALux can no longer be installed there.

- The results overview of the road calculation was sometimes not correct when "Calculate wet roadway surface" was activated.

- Some values could not be entered in the false color scale.

- Work areas were sometimes inserted at the wrong height.

- UGR results were sometimes not displayed in the documentation.

- Drag&drop of materials no longer worked as desired

- The maintenance factor was not updated when changing the cleaning interval.

- Crashes (some older projects, when saving after importing furniture).

- Translation errors
