* Bug fixes
tail's --follow=name option no longer implies --retry on systems
with inotify support. [bug introduced in coreutils-7.5]
* Changes in behavior
cp's extent-based (FIEMAP) copying code is more reliable in the face
of varying and undocumented file system semantics:
- it no longer treats unwritten extents specially
- a FIEMAP-based extent copy always uses the FIEMAP_FLAG_SYNC flag.
Before, it would incur the performance penalty of that sync only
for 2.6.38 and older kernels. We thought all problems would be
resolved for 2.6.39.
- it now attempts a FIEMAP copy only on a file that appears sparse.
Sparse files are relatively unusual, and the copying code incurs
the performance penalty of the now-mandatory sync only for them.

* Bug fixes
cp -a --link would not create a hardlink to a symlink, instead
copying the symlink and then not preserving its timestamp.
[bug introduced in coreutils-8.0]
cp now avoids FIEMAP issues with BTRFS before Linux 2.6.38,
which could result in corrupt copies of sparse files.
[bug introduced in coreutils-8.10]
cut could segfault when invoked with a user-specified output
delimiter and an unbounded range like "-f1234567890-".
[bug introduced in coreutils-5.3.0]
du would infloop when given --files0-from=DIR
[bug introduced in coreutils-7.1]
sort no longer spawns 7 worker threads to sort 16 lines
[bug introduced in coreutils-8.6]
touch built on Solaris 9 would segfault when run on Solaris 10
[bug introduced in coreutils-8.8]
wc would dereference a NULL pointer upon an early out-of-memory error
[bug introduced in coreutils-7.1]
** New features
dd now accepts the 'nocache' flag to the iflag and oflag options,
which will discard any cache associated with the files, or
processed portion thereof.
dd now warns that 'iflag=fullblock' should be used,
in various cases where partial reads can cause issues.
** Changes in behavior
cp now avoids syncing files when possible, when doing a FIEMAP copy.
The sync is only needed on Linux kernels before 2.6.39.
[The sync was introduced in coreutils-8.10]

* Bug fixes
- du would abort with a failed assertion when two conditions are
met: part of the hierarchy being traversed is moved to a higher
level in the directory tree, and there is at least one more
command line directory argument following the one containing
the moved sub-tree. [bug introduced in coreutils-5.1.0]
- join --header now skips the ordering check for the first line
even if the other file is empty. [bug introduced in
coreutils-8.5]
- rm -f no longer fails for EINVAL or EILSEQ on file systems that
reject file names invalid for that file system.
- uniq -f NUM no longer tries to process fields after end of
line. [bug introduced in coreutils-7.0]
* New features
- cp now copies sparse files efficiently on file systems with
FIEMAP support (ext4, btrfs, xfs, ocfs2). Before, it had to
read 2^20 bytes when copying a 1MiB sparse file. Now, it
copies bytes only for the non-sparse sections of a file.
Similarly, to induce a hole in the output file, it had to
detect a long sequence of zero bytes. Now, it knows precisely
where each hole in an input file is, and can reproduce them
efficiently in the output file. mv also benefits when it
resorts to copying, e.g., between file systems.
- join now supports -o 'auto' which will automatically infer the
output format from the first line in each file, to ensure the
same number of fields are output for each line.
* Changes in behavior
- join no longer reports disorder when one of the files is empty.

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