    3.11
	Improvements
	  Programs now quote file names more consistently in diagnostics.
	   For example; "cmp 'none of' /etc/passwd" now might output
	   "cmp: EOF on ‘none of’ which is empty" instead of outputting
	   "cmp: EOF on none of which is empty".  In diagnostic messages
	   that traditionally omit quotes and where backward compatibility
	   seems to be important, programs continue to omit quotes unless
	   a file name contains shell metacharacters, in which case programs
	   use shell quoting.  For example, although diff continues to output
	   "Only in a: b" as before for most file names, it now outputs
	   "Only in 'a: b': 'c: d'" instead of "Only in a: b: c: d" because the
	   file names 'a: b' and 'c: d' contain spaces.  For compatibility
	   with previous practice, diff -c and -u headers continue to quote for
	   C rather than for the shell.
	  diff now outputs more information when symbolic links differ, e.g.,
	   "Symbolic links ‘d/f’ -> ‘a’ and ‘e/f’ -> ‘b’ differ", not just
	   "Symbolic links d/f and e/f differ".  Special files too, e.g.,
	   "Character special files ‘d/f’ (1, 3) and ‘e/f’ (5, 0) differ", not
	   "File d/f is a character special file while file e/f is a character
	   special file".
	  diff's --ignore-case (-i) and --ignore-file-name-case options now
	   support multi-byte characters.  For example, they treat Greek
	   capital Δ like small δ when input uses UTF-8.
	  diff now supports multi-byte characters when treating white space.
	   In options like --expand-tabs (-t), --ignore-space-change (-b) and
	   --ignore-tab-expansion (-E), diff now recognizes non-ASCII space
	   characters and counts columns for non-ASCII characters.
	Bug fixes
	  cmp -bl no longer omits "M-" from bytes with the high bit set in
	   single-byte locales like en_US.iso8859-1.  This fix causes the
	   behavior to be locale independent, and to be the same as the
	   longstanding behavior in the C locale and in locales using UTF-8.
	   [bug introduced in 2.9]
	  cmp -i N and -n N no longer fail merely because N is enormous.
	   [bug present since "the beginning"]
	  cmp -s no longer mishandles /proc files, for which the Linux kernel
	   reports a zero size even when nonempty.  For example, the following
	   shell command now outputs nothing, as it should:
	     cp /proc/cmdline t; cmp -s /proc/cmdline t || echo files differ
	   [bug present since "the beginning"]
	  diff -E no longer mishandles some input lines containing '\a', '\b',
	   '\f', '\r', '\v', or '\0'.
	   [bug present since 2.8]
	  diff -ly no longer mishandles non-ASCII input.
	   [bug#64461 introduced in 2.9]
	  diff - A/B now works correctly when standard input is a directory,
	   by reading a file named B in that directory.
	   [bug present since "the beginning"]
	  diff no longer suffers from race conditions in some cases
	   when comparing files in a mutating file system.
	   [bug present since "the beginning"]
	Release
	  distribute gzip-compressed tarballs once again
