Tested this with Wolverine GUI install, and using Swedish. The "Release Notes" button at the bottom of the screen isn't translated, but the topic of the dialog, presented when clicking that button, is. Since the strings are identical on both places, I think this indicates that the button caption isn't marked for translation. This should probably be corrected.
Thanks. The button has now been marked for translation. However, this only appears to be working for some languages. Investigating further.
Button is working now. For some languages such as Hungarian, the release notes button has not been translated yet.
