The Help/About LibreOffice dialog shows the incorrect copyright date string. It currently reads: "Copyright (C) 2000-2017 LibreOffice contributors." It should read "Copyright (C) 2000-2018 LibreOffice contributors." To reproduce: In any LibreOffice application, click Help and then About LibreOffice. Severity: Minor/Low.
Thanks for reporting the issue. This is similar to bug 105789. As in bug 105789, it can't be backported to 6.0 branch because the 'Hard English string & UI freeze' was reached before the end of 2017. Anyway, Copyright in the work expires 70 years after the death of the author. Closing as RESOLVED WONTFIX
