         Please always test if the bug is still reproducible in the latest development version. We are constantly improving JabRef and some bugs may already be fixed. If you already use a development version, ensure that you use the latest one.
         You can download the latest development build at: https://builds.jabref.org/main/ . **Please make a backup of your library before you try out this version.**
