+        * MKVToolNix GUI: new merge tool feature: dragging & dropping
+        files onto line edit controls that expect file names (e.g. the
+        »chapter file« control) will set that line edit's test to the
+        dropped file name. Implements #1344.
+
         * mkvmerge: bug fix: track statistics tags can be kept with the
         option »--engage keep_track_statistics_tags«. This allows
         outputting them in verbose identification mode for easier
