When opening the "About Falkon" menu, you see these lines: QupZilla-Version: 3.0.0 QtWebEngine-Version 5.10.0 Falkon 3.0.0-1.1 openSUSE Tumbleweed 20180320
There is no such string, it is (notice no slashes and no uppercase v): Application version 3.0.99 QtWebEngine version 5.10.1 Do you perhaps have it translated? In that case it could be still showing QupZilla as translations were imported from QupZilla.
Yes, I am using the German translation.
In that case the issue must be in German translation.
Any reason why it's "Application version" and not "Falkon version" now?
Falkon 3.0.1 now shows "Anwendungsversion: 3.0.1" in the about dialog (Application Version), so this is fixed.
