 ** Changes in behavior

+  df avoids long UUID-including file system names in the default listing.

   tail -f now uses polling (not inotify) when any of its file arguments
   resides on a file system of unknown type.  In addition, for each such
   argument, tail -f prints a warning with the FS type magic number and a
   request to report it to the bug-reporting address.
