-* Noteworthy changes in release ?.? (????-??-??) [?]
+* Noteworthy changes in release 8.4 (2010-01-13) [stable]
+
+** Bug fixes
+
+  nproc --all is now guaranteed to be as large as the count
+  of available processors, which may not have been the case
+  on GNU/Linux systems with neither /proc nor /sys available.
+  [bug introduced in coreutils-8.1]
+
+** Build-related
+
+  Work around a build failure when using buggy <sys/capability.h>.
+  Alternatively, configure with --disable-libcap.
+
+  Compilation would fail on systems using glibc-2.7..2.9 due to changes in
+  gnulib's wchar.h that tickled a bug in at least those versions of glibc's
+  own <wchar.h> header.  Now, gnulib works around the bug in those older
+  glibc <wchar.h> headers.
+
+  Building would fail with a link error (cp/copy.o) when XATTR headers
+  were installed without the corresponding library.  Now, configure
+  detects that and disables xattr support, as one would expect.
+
+
+* Noteworthy changes in release 8.3 (2010-01-07) [stable]
+
+** Bug fixes
+
+  cp -p, install -p, mv, and touch -c could trigger a spurious error
+  message when using new glibc coupled with an old kernel.
+  [bug introduced in coreutils-6.12].
+
+  ls -l --color no longer prints "argetm" in front of dangling
+  symlinks when the 'LINK target' directive was given to dircolors.
+  [bug introduced in fileutils-4.0]
+
+  pr's page header was improperly formatted for long file names.
+  [bug introduced in coreutils-7.2]
+
+  rm -r --one-file-system works once again.
+  The rewrite to make rm use fts introduced a regression whereby
+  a commmand of the above form would fail for all subdirectories.
+  [bug introduced in coreutils-8.0]
+
+  stat -f recognizes more file system types: k-afs, fuseblk, gfs/gfs2, ocfs2,
+  and rpc_pipefs. Also Minix V3 is displayed correctly as minix3, not minux3.
+  [bug introduced in coreutils-8.1]
+
+  tail -f (inotify-enabled) once again works with remote files.
+  The use of inotify with remote files meant that any changes to those
+  files that was not done from the local system would go unnoticed.
+  [bug introduced in coreutils-7.5]
+
+  tail -F (inotify-enabled) would abort when a tailed file is repeatedly
+  renamed-aside and then recreated.
+  [bug introduced in coreutils-7.5]
+
+  tail -F (inotify-enabled) could fail to follow renamed files.
+  E.g., given a "tail -F a b" process, running "mv a b" would
+  make tail stop tracking additions to "b".
+  [bug introduced in coreutils-7.5]
+
+  touch -a and touch -m could trigger bugs in some file systems, such
+  as xfs or ntfs-3g, and fail to update timestamps.
+  [bug introduced in coreutils-8.1]
+
+  wc now prints counts atomically so that concurrent
+  processes will not intersperse their output.
+  [the issue dates back to the initial implementation]
+
+
+* Noteworthy changes in release 8.2 (2009-12-11) [stable]
+
+** Bug fixes
+
+  id's use of mgetgroups no longer writes beyond the end of a malloc'd buffer
+  [bug introduced in coreutils-8.1]
+
+  id no longer crashes on systems without supplementary group support.
+  [bug introduced in coreutils-8.1]
+
+  rm once again handles zero-length arguments properly.
+  The rewrite to make rm use fts introduced a regression whereby
+  a command like "rm a '' b" would fail to remove "a" and "b", due to
+  the presence of the empty string argument.
+  [bug introduced in coreutils-8.0]
+
+  sort is now immune to the signal handling of its parent.
+  Specifically sort now doesn't exit with an error message
+  if it uses helper processes for compression and its parent
+  ignores CHLD signals. [bug introduced in coreutils-6.9]
+
+  tail without -f no longer access uninitialized memory
+  [bug introduced in coreutils-7.6]
+
+  timeout is now immune to the signal handling of its parent.
+  Specifically timeout now doesn't exit with an error message
+  if its parent ignores CHLD signals. [bug introduced in coreutils-7.6]
+
+  a user running "make distcheck" in the coreutils source directory,
+  with TMPDIR unset or set to the name of a world-writable directory,
+  and with a malicious user on the same system
+  was vulnerable to arbitrary code execution
+  [bug introduced in coreutils-5.0]

  Even then, chcon may still be useful.
  [bug introduced in coreutils-8.0]

+  chcon, chgrp, chmod, chown and du now diagnose an ostensible directory cycle
+  and arrange to exit nonzero.  Before, they would silently ignore the
+  offending directory and all "contents."
+
+  env -u A=B now fails, rather than silently adding A to the
+  environment.  Likewise, printenv A=B silently ignores the invalid
+  name.  [the bugs date back to the initial implementation]
+
+  ls --color now handles files with capabilities correctly.  Previously
+  files with capabilities were often not colored, and also sometimes, files
+  without capabilites were colored in error. [bug introduced in coreutils-7.0]
+
+  md5sum now prints checksums atomically so that concurrent
+  processes will not intersperse their output.
+  This also affected sum, sha1sum, sha224sum, sha384sum and sha512sum.
+  [the bug dates back to the initial implementation]
+
+  mktemp no longer leaves a temporary file behind if it was unable to
+  output the name of the file to stdout.
+  [the bug dates back to the initial implementation]
+
+  nice -n -1 PROGRAM now runs PROGRAM even when its internal setpriority
+  call fails with errno == EACCES.
+  [the bug dates back to the initial implementation]
+
+  nice, nohup, and su now refuse to execute the subsidiary program if
+  they detect write failure in printing an otherwise non-fatal warning
+  message to stderr.
+
  stat -f recognizes more file system types: afs, cifs, anon-inode FS,
  btrfs, cgroupfs, cramfs-wend, debugfs, futexfs, hfs, inotifyfs, minux3,
  nilfs, securityfs, selinux, xenfs

+  tail -f (inotify-enabled) now avoids a race condition.
+  Before, any data appended in the tiny interval between the initial
+  read-to-EOF and the inotify watch initialization would be ignored
+  initially (until more data was appended), or forever, if the file
+  were first renamed or unlinked or never modified.
+  [The race was introduced in coreutils-7.5]
+
+  tail -F (inotify-enabled) now consistently tails a file that has been
+  replaced via renaming.  That operation provokes either of two sequences
+  of inotify events.  The less common sequence is now handled as well.
+  [The bug came with the implementation change in coreutils-7.5]
+
+  timeout now doesn't exit unless the command it is monitoring does,
+  for any specified signal. [bug introduced in coreutils-7.0].
+
+** Changes in behavior
+
+  chroot, env, nice, and su fail with status 125, rather than 1, on
+  internal error such as failure to parse command line arguments; this
+  is for consistency with stdbuf and timeout, and avoids ambiguity
+  with the invoked command failing with status 1.  Likewise, nohup
+  fails with status 125 instead of 127.
+
+  du (due to a change in gnulib's fts) can now traverse NFSv4 automounted
+  directories in which the stat'd device number of the mount point differs
+  during a traversal.  Before, it would fail, because such a mismatch would
+  usually represent a serious error or a subversion attempt.
+
+  echo and printf now interpret \e as the Escape character (0x1B).
+
+  rm -f /read-only-fs/nonexistent now succeeds and prints no diagnostic
+  on systems with an unlinkat syscall that sets errno to EROFS in that case.
+  Before, it would fail with a "Read-only file system" diagnostic.
+  Also, "rm /read-only-fs/nonexistent" now reports "file not found" rather
+  than the less precise "Read-only file system" error.
+
+** New programs
+
+  nproc: Print the number of processing units available to a process.
+
 ** New features

+  env and printenv now accept the option --null (-0), as a means to
+  avoid ambiguity with newlines embedded in the environment.
+
  md5sum --check now also accepts openssl-style checksums.
  So do sha1sum, sha224sum, sha384sum and sha512sum.

+  mktemp now accepts the option --suffix to provide a known suffix
+  after the substitution in the template.  Additionally, uses such as
+  "mktemp fileXXXXXX.txt" are able to infer an appropriate --suffix.
+
+  touch now accepts the option --no-dereference (-h), as a means to
+  change symlink timestamps on platforms with enough support.
+

+and with a @var{template} including a run of @var{n} instances of @samp{X},
+there are @samp{62**@var{n}} potential file names.
+
+Older scripts used to create temporary files by simply joining the
+name of the program with the process id (@samp{$$}) as a suffix.
+However, that naming scheme is easily predictable, and suffers from a
+race condition where the attacker can create an appropriately named
+symbolic link, such that when the script then opens a handle to what
+it thought was an unused file, it is instead modifying an existing
+file.  Using the same scheme to create a directory is slightly safer,
+since the @command{mkdir} will fail if the target already exists, but
+it is still inferior because it allows for denial of service attacks.
+Therefore, modern scripts should use the @command{mktemp} command to
+guarantee that the generated name will be unpredictable, and that
+knowledge of the temporary file name implies that the file was created
+by the current script and cannot be modified by other users.
+
+When creating a file, the resulting file has read and write
+permissions for the current user, but no permissions for the group or
+others; these permissions are reduced if the current umask is more
+restrictive.
+
+Here are some examples (although note that if you repeat them, you
+will most likely get different file names):
+
+@itemize @bullet
+
+@item
+Create a temporary file in the current directory.
+@example
+$ mktemp file.XXXX
+file.H47c
+@end example
+
+@item
+Create a temporary file with a known suffix.
+@example
+$ mktemp --suffix=.txt file-XXXX
+file-H08W.txt
+$ mktemp file-XXXX-XXXX.txt
+file-XXXX-eI9L.txt
+@end example
+
+@item
+Create a secure fifo relative to the user's choice of @env{TMPDIR},
+but falling back to the current directory rather than @file{/tmp}.
+Note that @command{mktemp} does not create fifos, but can create a
+secure directory in which the fifo can live.  Exit the shell if the
+directory or fifo could not be created.
+@example
+$ dir=$(mktemp -p "$@{TMPDIR:-.@}" -d dir-XXXX) || exit 1
+$ fifo=$dir/fifo
+$ mkfifo "$fifo" || @{ rmdir "$dir"; exit 1; @}
+@end example
+
+@item
+Create and use a temporary file if possible, but ignore failure.  The
+file will reside in the directory named by @env{TMPDIR}, if specified,
+or else in @file{/tmp}.
+@example
+$ file=$(mktemp -q) && @{
+>   # Safe to use $file only within this block.  Use quotes,
+>   # since $TMPDIR, and thus $file, may contain whitespace.
+>   echo ... > "$file"
+>   rm "$file"
+> @}
+@end example
+
+@item
+Act as a semi-random character generator (it is not fully random,
+since it is impacted by the contents of the current directory).  To
+avoid security holes, do not use the resulting names to create a file.
+@example
+$ mktemp -u XXX
+Gb9
+$ mktemp -u XXX
+nzC
+@end example
+
+@end itemize
+
+The program accepts the following options.  Also see @ref{Common options}.
+
+@table @samp
+
+@item -d
+@itemx --directory
+@opindex -d
+@opindex --directory
+Create a directory rather than a file.  The directory will have read,
+write, and search permissions for the current user, but no permissions
+for the group or others; these permissions are reduced if the current
+umask is more restrictive.
+
+@item -q
+@itemx --quiet
+@opindex -q
+@opindex --quiet
+Suppress diagnostics about failure to create a file or directory.  The
+exit status will still reflect whether a file was created.
+
+@item -u
+@itemx --dry-run
+@opindex -u
+@opindex --dry-run
+Generate a temporary name that does not name an existing file, without
+changing the file system contents.  Using the output of this command
+to create a new file is inherently unsafe, as there is a window of
+time between generating the name and using it where another process
+can create an object by the same name.
+
+@item -p @var{dir}
+@itemx --tmpdir[=@var{dir}]
+@opindex -p
+@opindex --tmpdir
+Treat @var{template} relative to the directory @var{dir}.  If
+@var{dir} is not specified (only possible with the long option
+@option{--tmpdir}) or is the empty string, use the value of
+@env{TMPDIR} if available, otherwise use @samp{/tmp}.  If this is
+specified, @var{template} must not be absolute.  However,
+@var{template} can still contain slashes, although intermediate
+directories must already exist.
+
+@item --suffix=@var{suffix}
+@opindex --suffix
+Append @var{suffix} to the @var{template}.  @var{suffix} must not
+contain slash.  If @option{--suffix} is specified, @var{template} must
+end in @samp{X}; if it is not specified, then an appropriate
+@option{--suffix} is inferred by finding the last @samp{X} in
+@var{template}.  This option exists for use with the default
+@var{template} and for the creation of a @var{suffix} that starts with
+@samp{X}.
+
+@item -t
+@opindex -t
+Treat @var{template} as a single file relative to the value of
+@env{TMPDIR} if available, or to the directory specified by
+@option{-p}, otherwise to @samp{/tmp}.  @var{template} must not
+contain slashes.  This option is deprecated; the use of @option{-p}
+without @option{-t} offers better defaults (by favoring the command
+line over @env{TMPDIR}) and more flexibility (by allowing intermediate
+directories).
