An updated package, coreutils-8.8-1 release has been uploaded and will
soon reach a mirror near you, leaving coreutils 8.5-2 as previous.

NEWS:
=====
This is a new upstream release, with upstream details listed below.  It
also includes a change to 'df -l' to better recognize local drives.

If you encounter a regression, please report it here rather than
upstream.  See also the upstream documentation in /usr/share/doc/coreutils/.

Help in porting the stdbuf utility to cygwin would be appreciated.

DESCRIPTION:
============
GNU coreutils provides a collection of commonly used utilities essential
to a standard POSIX environment.  It comprises the former textutils,
sh-utils, and fileutils packages.  The following executables are included:

[ arch base64 basename cat chcon chgrp chmod chown chroot cksum comm cp
csplit cut date dd df dir dircolors dirname du echo env expand expr
factor false fmt fold gkill groups head hostid hostname id install join
link ln logname ls md5sum mkdir mkfifo mknod mktemp mv nice nl nohup
nproc od paste pathchk pinky pr printenv printf ptx pwd readlink rm
rmdir runcon seq sha1sum sha224sum sha256sum sha384sum sha512sum shred
shuf sleep sort split stat stty su sum sync tac tail tee test timeout
touch tr true truncate tsort tty uname unexpand uniq unlink users vdir
wc who whoami yes

UPDATE:
=======

* Noteworthy changes in release 8.8 (2010-12-22) [stable]

** Bug fixes

  cp -u no longer does unnecessary copying merely because the source
  has finer-grained time stamps than the destination.

  od now prints floating-point numbers without losing information, and
  it no longer omits spaces between floating-point columns in some cases.

  sort -u with at least two threads could attempt to read through a
  corrupted pointer. [bug introduced in coreutils-8.6]

  sort with at least two threads and with blocked output would busy-loop
  (spinlock) all threads, often using 100% of available CPU cycles to
  do no work.  I.e., "sort < big-file | less" could waste a lot of power.
  [bug introduced in coreutils-8.6]

  sort with at least two threads no longer segfaults due to use of pointers
  into the stack of an expired thread. [bug introduced in coreutils-8.6]

  sort --compress no longer mishandles subprocesses' exit statuses,
  no longer hangs indefinitely due to a bug in waiting for subprocesses,
  and no longer generates many more than NMERGE subprocesses.

  sort -m -o f f ... f no longer dumps core when file descriptors are limited.

** Changes in behavior

  sort will not create more than 8 threads by default due to diminishing
  performance gains.  Also the --parallel option is no longer restricted
  to the number of available processors.

** New features

  split accepts the --number option to generate a specific number of files.


* Noteworthy changes in release 8.7 (2010-11-13) [stable]

** Bug fixes

  cp, install, mv, and touch no longer crash when setting file times
  on Solaris 10 Update 9 [Solaris PatchID 144488 and newer expose a
  latent bug introduced in coreutils 8.1, and possibly a second latent
  bug going at least as far back as coreutils 5.97]

  csplit no longer corrupts heap when writing more than 999 files,
  nor does it leak memory for every chunk of input processed
  [the bugs were present in the initial implementation]

  tail -F once again notices changes in a currently unavailable
  remote directory [bug introduced in coreutils-7.5]

** Changes in behavior

  cp --attributes-only now completely overrides --reflink.
  Previously a reflink was needlessly attempted.

  stat's %X, %Y, and %Z directives once again print only the integer
  part of seconds since the epoch.  This reverts a change from
  coreutils-8.6, that was deemed unnecessarily disruptive.
  To obtain a nanosecond-precision time stamp for %X use %.X;
  if you want (say) just 3 fractional digits, use %.3X.
  Likewise for %Y and %Z.

  stat's new %W format directive would print floating point seconds.
  However, with the above change to %X, %Y and %Z, we've made %W work
  the same way as the others.


* Noteworthy changes in release 8.6 (2010-10-15) [stable]

** Bug fixes

  du no longer multiply counts a file that is a directory or whose
  link count is 1, even if the file is reached multiple times by
  following symlinks or via multiple arguments.

  du -H and -L now consistently count pointed-to files instead of
  symbolic links, and correctly diagnose dangling symlinks.

  du --ignore=D now ignores directory D even when that directory is
  found to be part of a directory cycle.  Before, du would issue a
  "NOTIFY YOUR SYSTEM MANAGER" diagnostic and fail.

  split now diagnoses read errors rather than silently exiting.
  [bug introduced in coreutils-4.5.8]

  tac would perform a double-free when given an input line longer than 16KiB.
  [bug introduced in coreutils-8.3]

  tail -F once again notices changes in a currently unavailable directory,
  and works around a Linux kernel bug where inotify runs out of resources.
  [bugs introduced in coreutils-7.5]

  tr now consistently handles case conversion character classes.
  In some locales, valid conversion specifications caused tr to abort,
  while in all locales, some invalid specifications were undiagnosed.
  [bugs introduced in coreutils 6.9.90 and 6.9.92]

** New features

  cp now accepts the --attributes-only option to not copy file data,
  which is useful for efficiently modifying files.

  du recognizes -d N as equivalent to --max-depth=N, for compatibility
  with FreeBSD.

  sort now accepts the --debug option, to highlight the part of the
  line significant in the sort, and warn about questionable options.

  sort now supports -d, -f, -i, -R, and -V in any combination.

  stat now accepts the %m format directive to output the mount point
  for a file.  It also accepts the %w and %W format directives for
  outputting the birth time of a file, if one is available.

** Changes in behavior

  df now consistently prints the device name for a bind mounted file,
  rather than its aliased target.

  du now uses less than half as much memory when operating on trees
  with many hard-linked files.  With --count-links (-l), or when
  operating on trees with no hard-linked files, there is no change.

  ls -l now uses the traditional three field time style rather than
  the wider two field numeric ISO style, in locales where a style has
  not been specified.  The new approach has nicer behavior in some
  locales, including English, which was judged to outweigh the disadvantage
  of generating less-predictable and often worse output in poorly-configured
  locales where there is an onus to specify appropriate non-default styles.
  [The old behavior was introduced in coreutils-6.0 and had been removed
   for English only using a different method since coreutils-8.1]

  rm's -d now evokes an error;  before, it was silently ignored.

  sort -g now uses long doubles for greater range and precision.

  sort -h no longer rejects numbers with leading or trailing ".", and
  no longer accepts numbers with multiple ".".  It now considers all
  zeros to be equal.

  sort now uses the number of available processors to parallelize
  the sorting operation.  The number of sorts run concurrently can be
  limited with the --parallel option or with external process
  control like taskset for example.

  stat now provides translated output when no format is specified.

  stat no longer accepts the --context (-Z) option.  Initially it was
  merely accepted and ignored, for compatibility.  Starting two years
  ago, with coreutils-7.0, its use evoked a warning.  Printing the
  SELinux context of a file can be done with the %C format directive,
  and the default output when no format is specified now automatically
  includes %C when context information is available.

  stat no longer accepts the %C directive when the --file-system
  option is in effect, since security context is a file attribute
  rather than a file system attribute.

  stat now outputs the full sub-second resolution for the atime,
  mtime, and ctime values since the Epoch, when using the %X, %Y, and
  %Z directives of the --format option.  This matches the fact that
  %x, %y, and %z were already doing so for the human-readable variant.

  touch's --file option is no longer recognized.  Use --reference=F (-r)
  instead.  --file has not been documented for 15 years, and its use has
  elicited a warning since coreutils-7.1.

  truncate now supports setting file sizes relative to a reference file.
  Also errors are no longer suppressed for unsupported file types, and
  relative sizes are restricted to supported file types.
