   All utilities now quote user supplied arguments in error strings,
   which avoids confusing error messages in the presence of '\r' chars etc.
 
+  Utilities that traverse directories, like chmod, cp, and rm etc., will 
operate
+  more efficiently on XFS and in more cases on NFS, through "leaf 
optimization".
+
   md5sum now ensures a single line per file for status on standard output,
   by using a '\' at the start of the line, and replacing any newlines with 
'\n'.
   This also affects sha1sum, sha224sum, sha256sum, sha384sum and sha512sum.
