* Noteworthy changes in release ?.? (????-??-??) [?]
+** New features
+
+ df now accepts the --output[=FIELD_LIST] option to define the list of columns
+ to include in the output, or all available columns if the FIELD_LIST is
+ omitted. Note this enables df to output both block and inode fields together.
+
+** Bug fixes
+
+ cp --no-preserve=mode now no longer exits non-zero.
+ [bug introduced in coreutils-8.20]
+
+ cut with a range like "N-" no longer allocates N/8 bytes. That buffer
+ would never be used, and allocation failure could cause cut to fail.
+ [bug introduced in coreutils-8.10]
+
+ cut no longer accepts the invalid range 0-, which made it print empty lines.
+ Instead, cut now fails and emits an appropriate diagnostic.
+ [This bug was present in "the beginning".]
+
+ cut now handles overlapping to-EOL ranges properly. Before, it would
+ interpret "-b2-,3-" like "-b3-". Now it's treated like "-b2-".
+ [This bug was present in "the beginning".]
+
+ cut no longer prints extraneous delimiters when a to-EOL range subsumes
+ another range. Before, "echo 123|cut --output-delim=: -b2-,3" would print
+ "2:3". Now it prints "23". [bug introduced in 5.3.0]
+
+ factor no longer loops infinitely on 32 bit powerpc systems.
+ [bug introduced in coreutils-8.20]
+
+ install -m M SOURCE DEST no longer has a race condition where DEST's
+ permissions are temporarily derived from SOURCE instead of from M.
+
+ pr -n no longer crashes when passed values >= 32. Also line numbers are
+ consistently padded with spaces, rather than with zeros for certain widths.
+ [bug introduced in TEXTUTILS-1_22i]
+
+ seq -w ensures that for numbers input in scientific notation,
+ the output numbers are properly aligned and of the correct width.
+ [This bug was present in "the beginning".]
+
+** Changes in behavior
+
+ df --total now prints '-' into the target column (mount point) of the
+ summary line, accommodating to the --output option where the target
+ field can be in any column. If there is no source column, then df
+ prints 'total' into the target column.
+
+ df now properly outputs file system information with bind mounts present on
+ the system by skipping duplicate entries (identified by the device number).
+
+ df now skips the early-boot pseudo file system type "rootfs" unless either
+ the -a option or "-t rootfs" is specified.
+
+ nl no longer supports the --page-increment option which was deprecated
+ since coreutils-7.5. Use --line-increment instead.
+
+** Improvements
+
+ stat and tail now know about CEPH. stat -f --format=%T now reports the file
+ system type, and tail -f uses polling for files on CEPH file systems.
+
+
+** Build-related
+
+ Perl is now more of a prerequisite. It has long been required in order
+ to run (not skip) a significant percentage of the tests. Now, it is
+ also required in order to generate proper man pages, via help2man. The
+ generated man/*.1 man pages are no longer distributed. Building without
+ perl, you would create stub man pages. Thus, while perl is not an
+ official prerequisite (build and "make check" will still succeed), any
+ resulting man pages would be inferior. In addition, this fixes a bug
+ in distributed (not from clone) Makefile.in that could cause parallel
+ build failure when building from modified sources, as is common practice
+ for a patched distribution package.
+
+ The check in the root-only tests to test whether our dummy user,
+ $NON_ROOT_USERNAME, is able to run binaries from the build directory
+ failed. As a result, these tests have been skipped unnecessarily.
+ [bug introduced in coreutils-8.20]
+
+
+* Noteworthy changes in release 8.20 (2012-10-23) [stable]
+
+** New features
+
+ dd now accepts 'status=none' to suppress all informational output.
+
+ md5sum now accepts the --tag option to print BSD-style output with GNU
+ file name escaping. This also affects sha1sum, sha224sum, sha256sum,
+ sha384sum and sha512sum.
+
+** Bug fixes
+
+ cp could read from freed memory and could even make corrupt copies.
+ This could happen with a very fragmented and sparse input file,
+ on GNU/Linux file systems supporting fiemap extent scanning.
+ This bug also affects mv when it resorts to copying, and install.
+ [bug introduced in coreutils-8.11]
+
+ cp --no-preserve=mode now no longer preserves the original file's
+ permissions but correctly sets mode specified by 0666 & ~umask
+
+ du no longer emits a "disk-corrupted"-style diagnostic when it detects
+ a directory cycle that is due to a bind-mounted directory. Instead,
+ it detects this precise type of cycle, diagnoses it as such and
+ eventually exits nonzero.
+
+ factor (when using gmp) would mistakenly declare some composite numbers
+ to be prime, e.g., 465658903, 2242724851, 6635692801 and many more.
+ The fix makes factor somewhat slower (~25%) for ranges of consecutive
+ numbers, and up to 8 times slower for some worst-case individual numbers.
+ [bug introduced in coreutils-7.0, with GNU MP support]
+
+ ls now correctly colors dangling symlinks when listing their containing
+ directories, with orphaned symlink coloring disabled in LS_COLORS.
+ [bug introduced in coreutils-8.14]
+
+ rm -i -d now prompts the user then removes an empty directory, rather
+ than ignoring the -d option and failing with an 'Is a directory' error.
+ [bug introduced in coreutils-8.19, with the addition of --dir (-d)]
+
+ rm -r S/ (where S is a symlink-to-directory) no longer gives the invalid
+ "Too many levels of symbolic links" diagnostic.
+ [bug introduced in coreutils-8.6]
+
+ seq now handles arbitrarily long non-negative whole numbers when the
+ increment is 1 and when no format-changing option is specified.
+ Before, this would infloop:
+ b=100000000000000000000; seq $b $b
+ [the bug dates back to the initial implementation]
+
+** Changes in behavior
+
+ nproc now diagnoses with an error, non option command line parameters.
+
+** Improvements
+
+ factor's core has been rewritten for speed and increased range.
+ It can now factor numbers up to 2^128, even without GMP support.
+ Its speed is from a few times better (for small numbers) to over
+ 10,000 times better (just below 2^64). The new code also runs a
+ deterministic primality test for each prime factor, not just a
+ probabilistic test.
+
+ seq is now up to 70 times faster than it was in coreutils-8.19 and prior,
+ but only with non-negative whole numbers, an increment of 1, and no
+ format-changing options.
+
+ stat and tail know about ZFS, VZFS and VMHGFS. stat -f --format=%T now
+ reports the file system type, and tail -f now uses inotify for files on
+ ZFS and VZFS file systems, rather than the default (for unknown file
+ system types) of issuing a warning and reverting to polling. tail -f
+ still uses polling for files on VMHGFS file systems.
+
+** Build-related
+
+ root-only tests now check for permissions of our dummy user,
+ $NON_ROOT_USERNAME, before trying to run binaries from the build directory.
+ Before, we would get hard-to-diagnose reports of failing root-only tests.
+ Now, those tests are skipped with a useful diagnostic when the root tests
+ are run without following the instructions in README.
+
+ We now build most directories using non-recursive make rules. I.e.,
+ rather than running make in man/, lib/, src/, tests/, instead, the top
+ level Makefile.am includes a $dir/local.mk that describes how to build
+ the targets in the corresponding directory. Two directories remain
+ unconverted: po/, gnulib-tests/. One nice side-effect is that the more
+ accurate dependencies have eliminated a nagging occasional failure that
+ was seen when running parallel "make syntax-check".
+
+
+* Noteworthy changes in release 8.19 (2012-08-20) [stable]
+
+** Bug fixes
+
+ df now fails when the list of mounted file systems (/etc/mtab) cannot
+ be read, yet the file system type information is needed to process
+ certain options like -a, -l, -t and -x.
+ [This bug was present in "the beginning".]
+
+ sort -u could fail to output one or more result lines.
+ For example, this command would fail to print "1":
+ (yes 7 | head -11; echo 1) | sort --p=1 -S32b -u
+ [bug introduced in coreutils-8.6]
+
+ sort -u could read freed memory.
+ For example, this evokes a read from freed memory:
+ perl -le 'print "a\n"."0"x900'|valgrind sort --p=1 -S32b -u>/dev/null
+ [bug introduced in coreutils-8.6]
+
+** New features
+
+ rm now accepts the --dir (-d) option which makes it remove empty directories.
+ Since removing empty directories is relatively safe, this option can be
+ used as a part of the alias rm='rm --dir'. This improves compatibility
+ with Mac OS X and BSD systems which also honor the -d option.
+
+
+* Noteworthy changes in release 8.18 (2012-08-12) [stable]
+
** Bug fixes
cksum now prints checksums atomically so that concurrent
date: invalid date '\260'
[This bug was present in "the beginning".]
+ df no longer outputs control characters present in the mount point name.
+ Such characters are replaced with '?', so for example, scripts consuming
+ lines output by df, can work reliably.
+ [This bug was present in "the beginning".]
+
+ df --total now exits with an appropriate diagnostic and error code, when
+ file system --type options do not lead to a processed file system.
+ [This bug dates back to when --total was added in coreutils-7.0]
+
head --lines=-N (-n-N) now resets the read pointer of a seekable input file.
This means that "head -n-3" no longer consumes all of its input, and lines
not output by head may be processed by other programs. For example, this
or unwritable output. Sort now diagnoses certain errors at start-up,
rather than after potentially expensive processing.
+ sort now allocates no more than 75% of physical memory by default,
+ to better share system resources, and thus operate more efficiently.
+ [The default max memory usage changed from 50% to 100% in coreutils-8.16]
+
* Noteworthy changes in release 8.17 (2012-05-10) [stable]
join --header now skips the ordering check for the first line
even if the other file is empty. [bug introduced in coreutils-8.5]
+ join -v2 now ensures the default output format prints the match field
+ at the start of the line when it is different to the match field for
+ the first file. [bug present in "the beginning".]
+
rm -f no longer fails for EINVAL or EILSEQ on file systems that
reject file names invalid for that file system.
