* chmod -R no longer exits with error status when encountering symlinks.
All files would be processed correctly, but the exit status was incorrect.
* If 'cp -Z A B' checks B's status and some other process then removes B,
cp no longer creates B with a too-generous SELinux security context
before adjusting it to the correct value.
* 'cp --preserve=ownership A B' no longer ignores the umask when creating B.
Also, 'cp --preserve-xattr A B' is less likely to temporarily chmod u+w B.
* 'id xyz' now uses the name 'xyz' to determine groups, instead of xyz's uid.
* 'ls -v' and 'sort -V' no longer mishandle corner cases like "a..a" vs "a.+"
or lines containing NULs. Their behavior now matches the documentation
for file names like ".m4" that consist entirely of an extension,
and the documentation has been clarified for unusual cases.
* 'mv -T --backup=numbered A B/' no longer miscalculates the backup number
for B when A is a directory, possibly inflooping.
* cat now uses the copy_file_range syscall if available, when doing
simple copies between regular files. This may be more efficient, by avoiding
user space copies, and possibly employing copy offloading or reflinking.
* chown and chroot now warn about usages like "chown root.root f",
which have the nonstandard and long-obsolete "." separator that
causes problems on platforms where user names contain ".".
Applications should use ":" instead of ".".
* cksum no longer allows abbreviated algorithm names,
so that forward compatibility and robustness is improved.
* date +'%-N' now suppresses excess trailing digits, instead of always
padding them with zeros to 9 digits. It uses clock_getres and
clock_gettime to infer the clock resolution.
* dd conv=fsync now synchronizes output even after a write error,
and similarly for dd conv=fdatasync.
* dd now counts bytes instead of blocks if a block count ends in "B".
