+  chmod no longer fails in an environment (e.g., a chroot) with openat
+  support but with insufficient /proc support.
+
+  "cp --parents F/G D" no longer creates a directory D/F when F is not
+  a directory (and F/G is therefore invalid).
+
+  "cp --preserve=mode" would create directories that briefly had
+  too-generous permissions in some cases.  For example, when copying a
+  directory with permissions 777 the destination directory might
+  temporarily be setgid on some file systems, which would allow other
+  users to create subfiles with the same group as the directory.  Fix
+  similar problems with 'install' and 'mv'.
+
+  cut no longer dumps core for usage like "cut -f2- f1 f2" with two or
+  more file arguments.  This was due to a double-free bug, introduced
+  in coreutils-5.3.0.
+
+  dd bs= operands now silently override any later ibs= and obs=
+  operands, as POSIX and tradition require.
+
+  "ls -FRL" always follows symbolic links on Linux.  Introduced in
+  coreutils-6.0.
+
+  A cross-partition "mv /etc/passwd ~" (by non-root) now prints
+  a reasonable diagnostic.  Before, it would print this:
+  "mv: cannot remove `/etc/passwd': Not a directory".
+
+  pwd and "readlink -e ." no longer fail unnecessarily when a parent
+  directory is unreadable.
+
+  "rm -rf /etc/passwd" (run by non-root) now prints a diagnostic.
+  Before it would print nothing.
+
+  "rm --interactive=never F" no longer prompts for an unwritable F
+
+** New features
+
+  sort's new --compress-program=PROG option specifies a compression
+  program to use when writing and reading temporary files.
+  This can help save both time and disk space when sorting large inputs.
+
+** New features
+
+  sort accepts the new option -C, which acts like -c except no diagnostic
+  is printed.  Its --check option now accepts an optional argument, and
+  --check=quiet and --check=silent are now aliases for -C, while
+  --check=diagnose-first is an alias for -c or plain --check.
+
+
+* Noteworthy changes in release 6.7 (2006-12-08) [stable]
+
+** Bug fixes
+
+  When cp -p copied a file with special mode bits set, the same bits
+  were set on the copy even when ownership could not be preserved.
+  This could result in files that were setuid to the wrong user.
+  To fix this, special mode bits are now set in the copy only if its
+  ownership is successfully preserved.  Similar problems were fixed
+  with mv when copying across file system boundaries.  This problem
+  affects all versions of coreutils through 6.6.
+
+  cp --preserve=ownership would create output files that temporarily
+  had too-generous permissions in some cases.  For example, when
+  copying a file with group A and mode 644 into a group-B sticky
+  directory, the output file was briefly readable by group B.
+  Fix similar problems with cp options like -p that imply
+  --preserve=ownership, with install -d when combined with either -o
+  or -g, and with mv when copying across file system boundaries.
+  This bug affects coreutils 6.0 through 6.6.
+
+  du --one-file-system (-x) would skip subdirectories of any directory
+  listed as second or subsequent command line argument.  This bug affects
+  coreutils-6.4, 6.5 and 6.6.
+
+
+* Noteworthy changes in release 6.6 (2006-11-22) [stable]
+
+** Bug fixes
+
+  ls would segfault (dereference a NULL pointer) for a file with a
+  nameless group or owner.  This bug was introduced in coreutils-6.5.
+
+  A bug in the latest official m4/gettext.m4 (from gettext-0.15)
+  made configure fail to detect gettext support, due to the unusual
+  way in which coreutils uses AM_GNU_GETTEXT.
+
+** Improved robustness
+
+  Now, du (and the other fts clients: chmod, chgrp, chown) honor a
+  trailing slash in the name of a symlink-to-directory even on
+  Solaris 9, by working around its buggy fstatat implementation.
+
+
+* Major changes in release 6.5 (2006-11-19) [stable]
+
+** Bug fixes
+
+  du (and the other fts clients: chmod, chgrp, chown) would exit early
+  when encountering an inaccessible directory on a system with native
+  openat support (i.e., linux-2.6.16 or newer along with glibc-2.4
+  or newer).  This bug was introduced with the switch to gnulib's
+  openat-based variant of fts, for coreutils-6.0.

+** New features
+
+  rm accepts a new option: --one-file-system
+
+
+* Major changes in release 6.4 (2006-10-22) [stable]
+
+** Bug fixes
+
+  chgrp and chown would malfunction when invoked with both -R and -H and
+  with one or more of the following: --preserve-root, --verbose, --changes,
+  --from=o:g (chown only).  This bug was introduced with the switch to
+  gnulib's openat-based variant of fts, for coreutils-6.0.
+
+  cp --backup dir1 dir2, would rename an existing dir2/dir1 to dir2/dir1~.
+  This bug was introduced in coreutils-6.0.
+
+  With --force (-f), rm no longer fails for ENOTDIR.
+  For example, "rm -f existing-non-directory/anything" now exits

+------------------------

+If you use /usr/bin/make on an OSF/1 4.0d system, it will fail due

+
+Since the @var{owner} and @var{group} arguments to @command{chown} and
+@command{chgrp} may be specified as names or numeric IDs, there is an
+apparent ambiguity.
+What if a user or group @emph{name} is a string of digits?
+@footnote{Using a number as a user name is common in some environments.}
+Should the command interpret it as a user name or as an ID?
+@acronym{POSIX} requires that @command{chown} and @command{chgrp}
+first attempt to resolve the specified string as a name, and
+only once that fails, then try to interpret it as an ID.
+This is troublesome when you want to specify a numeric ID, say 42,
+and it must work even in a pathological situation where
+@samp{42} is a user name that maps to some other user ID, say 1000.
+Simply invoking @code{chown 42 F}, will set @file{F}s owner ID to
+1000---not what you intended.
+
+GNU @command{chown} and @command{chgrp} provide a way to work around this,
+that at the same time may result in a significant performance improvement
+by eliminating a database look-up.
+Simply precede each numeric user ID and/or group ID with a @samp{+},
+in order to force its interpretation as an integer:
+
+@example
+chown +42 F
+chgrp +$numeric_group_id another-file
+chown +0:+0 /
+@end example
+
+GNU @command{chown} and @command{chgrp}
+skip the name look-up process for each @samp{+}-prefixed string,
+because a string containing @samp{+} is never a valid user or group name.

+2007-02-23  Jim Meyering  <jim@meyering.net>
+
+	* randperm.c (randperm_new): Comment: say that this function
+	returns a pointer to malloc'd storage.
+
+2007-02-18  Jim Meyering  <jim@meyering.net>
+
+	* xfts.c: Include <stdlib.h> rather than exit.h, now that stdlib.h
+	is guaranteed to provide a valid definition of EXIT_FAILURE.
+
+2007-01-19  Jim Meyering  <jim@meyering.net>
+
+	* .cvsignore, .gitignore: Add sys, as well as more
+	bootstrap-inserted file names.
+
+2007-01-14  Jim Meyering  <jim@meyering.net>
+
+	* fchdir-stub.c: Remove file.  No longer needed.
+
+2006-12-03  Jim Meyering  <jim@meyering.net>
+
+	* Makefile.am (libcoreutils_a_SOURCES): Remove xmemcoll.c and
+	xmemcoll.h.  Now, they're handled by the gnulib xmemcoll module.
+
+2006-11-22  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* randread.c (__attribute__): Don't define if __attribute__ is
+	already defined.  Otherwise, the code won't conform to C99, since
+	the macro arg is spelled differently by some include file, and the
+	compilation fails with pedantic GCC.
+
+2006-11-22  Jim Meyering  <jim@meyering.net>
+
+	* .cvsignore, .gitignore: Add fstat.c.
+
+2006-11-14  Jim Meyering  <jim@meyering.net>
+
+	* readlink-stub.c, lstat-stub.c: Remove now-unused files.
+
+2006-10-14  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Port sha512sum to hosts where uintmax_t is only 32 bits, e.g.,
+	HP/Tandom NonStop OSS circa 2005 has 32-bit uintmax_t, 64-bit intmax_t.
+	* u64.h: New file.
+	* sha512.c (SWAP, sha512_init_ctx, sha384_init_ctx, sha512_read_ctx):
+	(sha384_read_ctx, sha512_conclude_ctx, sha512_process_bytes):
+	(sha512_round_constants, F2, F1, sha512_process_block):
+	(S0, S1, SS0, SS1, M, R):
+	Rewrite to use u64.h instead of assuming uint64_t.
+	* sha512.h: Include u64.h rather than stdint.h.
+	(rol64): Remove; moved to u64.h and renamed to u64rol.
+
+2006-10-12  Jim Meyering  <jim@meyering.net>
+
+	* Makefile.am (libcoreutils_a_LIBADD): Append $(LIBOBJS),
+	to accommodate the latest version of gnulib-tool.
+	(libcoreutils_a_DEPENDENCIES): Likewise.
+	From Bruno Haible.
+
+2006-10-06  Jim Meyering  <jim@meyering.net>
+
+	Avoid a compiler warning: const'ify and remove a cast.
+	* randread.c (struct randread_source) [handler]: Make parameter "const".
+	[handler_arg]: Add "const" attribute.
+	(randread_error): Make parameter "const".
+	(simple_new, randread_set_handler, randread_set_handler_arg): Likewise.
+	(randread_new): Remove now-unnecessary cast.
+	* randread.h: Adjust prototypes.
+
 2006-09-29  Paul Eggert  <eggert@cs.ucla.edu>
 
 	* .cvsignore: Add openat-proc.c.

+2007-01-19  Jim Meyering  <jim@meyering.net>
+
+	* .cvsignore, .gitignore: Add more bootstrap-inserted file names.
+
+2006-12-12  Jim Meyering  <jim@meyering.net>
+
+	* jm-macros.m4: Remove AC_FUNC_SETVBUF_REVERSED, now that it's a no-op.
+
+2006-10-14  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* sha512.m4 (gl_SHA512): Add u64.h to AC_LIBSOURCES.
+
+2006-10-12  Jim Meyering  <jim@meyering.net>
+
+	* jm-macros.m4 (coreutils_MACROS): Rename from gl_MACROS, now that
+	most of the gnulib macros have migrated into gnulib.
+	Don't call gl_INIT here (now it's called from configure.ac, directly).
+
+2006-10-07  Jim Meyering  <jim@meyering.net>
+
+	* jm-macros.m4 (gl_MACROS): Remove use of AC_CONFIG_LIBOBJ_DIR(lib).
+	It is no longer needed, and was causing dependencies to appear
+	in lib/lib/.deps, which provoked a "make distcheck" failure.
+
 2006-09-29  Jim Meyering  <jim@meyering.net>
 
 	* readdir.m4: Remove file once again.
