* Fix cp so that `cp -r DIR1/ DIR2' works properly once again.
* New ls option --quoting-style=clocale acts like --quoting-style=locale,
  except that it quotes "like this" by default instead of `like this'.
[4.0w]
* When `cp -pR' fails to copy a file, it now preserves permissions, owner,
   and group of the containing directory.
[4.0v]
* df, du, and ls now round disk usage up and disk free space down
* df, du, ls: --block-size=N now works for values of N that are e.g.,
    not a multiple of the file's block size
[4.0u]
* give proper diagnostic for mv usage error
* fix compile problem with lib/strnlen.c
[4.0t]
* `cp -d -u' no longer fails with certain existing destination symlinks
* rmdir and mkdir accept -v as synonym for --verbose
[4.0s]
* rm no longer segfaults on certain very deep hierarchies
* IMPORTANT SECURITY FIX: a running `rm -r' may no longer be subverted to
  remove unintended directories
* cp can now remove unwritable files in interactive mode; contrary to how mv
   works, cp's --interactive (-i) option does *not* cancel the effect of a
   preceding --force (-f) option.
* all programs fail when printing --help or --version output to a full device
* install no longer performs chmod if chown fails (see ChangeLog for example)
[4.0r]
* `du dir/subdir1 dir/subdir2' no longer fails
* chown accepts new option: --from=CURRENT_OWNER:CURRENT_GROUP
* cp accepts new option: --strip-trailing-slashes
* install --directory (-d) may now be used to set special bits
    e.g., `install -m a=rwx,o+t -d DIR' now honors the `o+t' part
* cp, mv, ln, install: document that while the --backup option takes an
  optional argument, the -b option accepts none
* `ls -e' fails with a more useful diagnostic
* df produces better output for loop file system mount points
[4.0q]
* install -D bug is fixed
* chown now works properly when the specified login name contains a period
  This is at the expense of always looking up the entire USER.GROUP string
  as a login name first, and only then (upon failure) interpreting the `.'
  as a separator and looking up `USER'.  To avoid the extra getpwnam call,
  always use the POSIX-mandated `:' character as the separator.
* `du some-other-dir' no longer fails if it can't open the current directory
* `mv DIR EXISTING-FILE' no longer removes EXISTING-FILE.  Now it gets an error
  as POSIX says it must.
* touch no longer hangs on fifos
[4.0p]
* various tools: quote multibyte characters correctly in diagnostics
* mv: portability fix for alpha
* dd: portability fix
* unified lib/: now that directory and most of the configuration framework
  is common between fileutils, textutils, and sh-utils
[4.0o]
* Include lib/nanosleep.h.
[4.0n]
* cp, install, ln, and mv: when making backup files in verbose mode, these
  commands now print the backup file name on the same line as the rest of the
  information, e.g., `a -> b (backup: b.~13~)' rather than on a separate line
  as all but ln used to do.  ln didn't output the backup file name at all.
[4.0m]
* mv accepts new option: --strip-trailing-slashes (soon, many other
  programs will, too)
* df no longer hangs when there is an inaccessible mount point unrelated to PATH
* rmdir --verbose no longer prints extra, bogus diagnosic upon failure
* fix df bug that made it print bogus values in the `Use%' column.
* touch -d once again parses dates with `hh:mm ZONE' time zone info.
[4.0l]
* ls -l honors a trailing slash on a symlink argument, per POSIX.
* shred no longer appears to infloop when asked to remove files in
  unwritable directories
* `ls -ul' and `ls -uc' sort by name once again, as they should
[4.0k]
* mv may now be used to move a file onto a symlink to itself when that
  symlink is on a separate partition.  With fileutils-4.0j, it would
  fail with a diagnostic saying they were the same file.
* touch would fail with the misleading diagnostic `no such file' when asked
  to create a file in an unwritable directory.  Now it says something like
  `permission denied' or `read-only file system'.
[4.0j]
* mkdir may now be used to set special bits  e.g., `mkdir -m o+t dir' works
* touch can now change the time(s) of a file you own even if you don't have
  read or write access to it
* rm no longer dumps core after warning about directory cycles
* mv now refuses to move a file onto a symlink to itself when that symlink
  is on a separate partition.  Before, it would remove the file and leave
  only the symlink.
* `install -d -g foo 1/2' now sets the `group' of the final component as well
  as that of the leading one.
* df, du, and ls no longer divide by zero when an invalid block size is
  specified through an environment variable
* under certain conditions, chgrp would fail to affect files referenced
  through symlinks.  Now it does.
* ln now makes hard links to symlinks on systems that support it.
* touch: no longer infloop on dangling symlinks
* cp, install, ln, mv: deprecate the --version-control option.  Use --backup's
  new optional argument instead.  The old option still works, but now evokes a
  warning.
* cp, install, ln, mv: the --backup option now accepts an optional argument
* cp, install, ln, mv: accept new option: --target-directory=DIR
* chgrp: accept new option, --dereference.  --no-dereference is now the default.
* New ls option --quoting-style=locale acts like --quoting-style=c, except
  with locale-specific quoting symbols (` and ' by default) instead of ".
* `df DIR' is less likely to hang due to bad NFS mounts
* As per POSIX.2, `df -P' now uses ceiling rather than rounding, and its
  header now says `1024-blocks ... Capacity' instead of `1k-blocks ... Use%'.
[4.0i]
* `cp -f FILE FILE' and `mv -f FILE FILE' no longer remove FILE
* touch works once again (DST-wise) when certain `--date DATE-TIME'
  values are specified.
* shred's -u option (short form of --remove) is now accepted
[4.0h]
* cp --one-file-system (-x) no longer crosses filesystem boundaries.
* touch can once again operate on directories
[4.0g]
* New large-file support for AIX and HP-UX, and for cross-compiles.
* shred's default options are now suitable for devices, not files, since
  shred is more reliable on devices.  shred now does not remove by default;
  the old -p or --preserve option was inverted and renamed to -u or --remove.
* shred -u now attempts to truncate devices before removing them.
* shred -v no longer outputs carriage-returns; shred -vv has no extra effect;
  shred -v now outputs to stderr.
* shred now tries to find the size of a non-regular file by seeking to its end.
* dd now opens the output file for *read* access only if `seek=' is used.
[4.0f]
* `ls --color' no longer segfaults
* dd works once again
[4.0e]
* shred --devices option renamed to -D so that -d, -i and -r can be
  compatible with rm.
* shred -s/--size=N option added to specify the size of the object to be
  shredded.
* `shred -' now shreds stdout rather than stdin.  This is incompatible with -v.
* shred now does not need to read from its output file, so opens it O_WRONLY
* `ls -l' uses `+' to designate each file that has a custom ACL
* eliminate race condition that could make touch truncate a nonempty file
* No longer use *_unlocked I/O macros on systems (like solaris5.5.1) where
  they're not declared, so selected executables (e.g., rm) that are linked
  with shared libraries will once again run on solaris5.6 systems.
[4.0d (aka 4.1-b3)]
* ls recognizes solaris 2 `doors'
* new program: shred
* ln: Allow creation of a hard link to a dangling symlink
* cp, mv, install: --verbose now prints a message for each backup-related
  renaming
* portability fixes for copy.c's code to detect move-directory-into-self
* upgrade to automake-1.3b
* upgrade to autoconf-2.13, and...
* remove some of the kludges in m4/*.m4 that permitted
[4.1-b2]
* concurrent `mkdir -p' processes no longer fail when creating the
  same hierarchy
* argmatch.c has been fixed so that the unambiguous usage `ls --color=n'
  no longer evokes an error.
* now, specifying an improper argument for an option that accepts enumerated
  values evokes diagnostics like this:
    $ src/touch --time=x file
    src/touch: invalid argument `x' for `--time'
    Valid arguments are:
      - `atime', `access', `use'
      - `mtime', `modify'
    Try `src/touch --help' for more information.
[4.1-b1]
* ls --quoting-style=c prints correct octal escapes for certain nonprinting
  characters in file names.
* fix `ls -R .' formatting bug that broke mktexlsr
* moving a directory into itself is properly diagnosed in more cases
* moving a directory containing hard-linked files now works

Changes in release 4.0:
[4.0-b7]
* rm -rf '' no longer gets a failed assertion on the Hurd
[4.0-b6]
* rm simply fails as it should (rather than segfaulting) for
  `mkdir -m 0100 x; rm -rf x'
[4.0-b5]
* still *more* mktime.c portability tweaks
[4.0-b4]
* mktime.c portability tweak for headers with GNU libc 5.4.44.
[4.0-b3]
* mktime.c works around problems with Digital Unix 4.0A and 4.0D.
* mktime.c handles dates in the spring-forward gap the same way other
  implementations do

[4.0-pre1]
* fix serious bug whereby `touch a b; echo n|mv -i a b' would remove b.
[3.16z]
* portability tweaks
* avoid `root `cp -a' from Netapp snapshot' corruption
[3.16y]
* `install -D' now works
* distribute maintainer Makefiles in man/
[3.16x]
* man pages are now automatically generated from a combination of --help
  output and the contents of new (though mostly empty), man/*.x files.
[3.16w]
* touch now interprets `-t TIME-DATE' as POSIX specifies
* `ls EMPTY-DIR EMPTY-DIR' once again outputs the directory names
[3.16v]
* portability fixes
* `ls -R EMPTY-DIR' now outputs the name of the directory
[3.16u]
* mv now fails (as it should) upon attempt to move a directory into itself
* `cp -a --one-file-system' now copies any mount point directories it
  encounters on the selected file system.
[3.16t]
* cp (with --update) and ls compare time stamps with subsecond resolution when
  available (e.g., on systems with recent Linux kernels and on Solaris 2.6).
* install once again does the -m-specified chmod *after* running strip
  (this fixes another bug introduced in 3.16o)
[3.16s]
* df accept a new option --local (-l)
* touch works around a system-specific bug so it now affects existing,
  zero-length files on certain systems
* chown now works even on certain SVR3 systems where it used to fail
[3.16r]
* include gettext's m4 macros
* minor cp bug fixed
* non-portable cp tests removed
* --without-included-regex now means don't compile regex.c
* rx support removed
[3.16q]
* `df', `du', and `ls' now accept a new option --block-size=SIZE,
  where SIZE can be a positive integer block size, followed by an
  optional SI prefix (e.g. `k' for kilo, `M' for Mega), followed by an
  optional `B' (for ``byte'', indicating powers of 1024, which is the
  default) or `D' (for ``decimal byte'', indicating powers of 1000).
  SIZE can also be `human-readable' (for -h or --human-readable
  behavior) or `si' (for -H or --si behavior).
* These suffixes can also be used by `dd'; e.g. `dd bs=1MB' is equivalent
  to `dd bs=1048576'.
* The default block size for the `df' command is now obtained from the
  DF_BLOCK_SIZE environment variable or, if that is not set, from BLOCK_SIZE.
  Similarly for `du' and `ls'.
* The output columns of `df' have been adjusted slightly to accommodate
  larger filesystems.
* fix gettext-related link failures seen when configuring certain ways
[3.16p]
* fix install bug introduced in 3.16o
* build/test changes only
[3.16o]
* chown accepts new option, --dereference.  --no-dereference is now the default.
* install now shares core copying code with mv and cp
* mv (between distinct filesystems) now uses more of the core copying code
* fixed a bug or two in mv
* df once again displays negative numbers when that's what's returned
  by get_fs_usage
