+      <para>
+        The source-side DND apis in GTK 4 have been changed to use a separate object, #GtkDragSource.

+      <para>
+        Instead of calling gtk_drag_source_set() and connecting to #GtkWidget signals, you create
+        a #GtkDragSource object, attach it to the widget with gtk_drag_source_attach(), and connect
+        to #GtkDragSource signals. The signals themselves are fairly similar.

+        Instead of calling gtk_drag_begin() on a widget, use a #GtkDragSource object and call
+        gtk_drag_source_drag_begin().
