 =head1 BUGS AND LIMITATIONS
 
-There is no detection for changed images, the thumbnails of deleted images are
-not removed.
+Thumbnails of changed images are not yet recreated.
 
 When used with B<-x>, the completer tar archive is kept in memory, leading to
 enormous memory usage and possibly out-of-memory errors.
