Comment (by Bruce Dubbs):
* Noteworthy changes in release 9.10 (2026-02-04) [stable]
* Bug fixes
cp, install, and mv no longer enter an infinite loop copying sparse
files
with SEEK_HOLE. E.g., this was seen on ext4 when copying sparse files
with
extents that are being actively updated, and copy offload is not being
used.
[bug introduced in coreutils-9.9]
'date' no longer fails with format directives that return an empty
string.
[bug introduced in coreutils-9.9]
'dd seek=N of=FILE' no longer continues copying, overwriting FILE if it
exists, if ftruncate fails.
[bug introduced in coreutils-9.1]
du and ls no longer modify strings returned by getenv.
POSIX says this is not portable.
[bug introduced in fileutils-4.1.6]
'fmt' now correctly diagnoses read errors.
Previously fmt generated a generic error for any read error.
[bug introduced in coreutils-9.0]
md5sum --text correctly translates CRLF line endings with the MSYS2
runtime.
This also applies to the sha*sum and b2sum utilities.
[This bug was present in "the beginning".]
'numfmt' no longer drops custom suffixes from numbers it cannot fully
parse.
[bug introduced with numfmt in coreutils-8.21]
'tail -f --pid' can no longer exit upon receiving a non terminating
signal.
On older Linux systems it may have failed with "Interrupted system
call".
[bug introduced in coreutils-7.5]
'timeout' will now propagate all terminating signals to the monitored
command.
Previously 'timeout' could have exited and left the monitored command
running.
[bug introduced with timeout in coreutils-7.0]
wc now documents its --debug option, currently used to
indicate the line count acceleration being used.
[bug introduced in coreutils-9.0]
When built with `clang -fno-inline`, memory allocation issues are again
handled in a defined manner. Previously programs may have crashed etc.
after a failure to allocate memory.
[bug introduced in coreutils-9.0]
* New Features
configure accepts a new --enable-single-binary=hardlinks mode to build
the
selected programs as hard links to a multi-call binary called
"coreutils".
This augments the existing "symlinks" and "shebangs" modes already
supported by the --enable-single-binary option.
'stat' and 'tail' now know about the "guest-memfd" file system type.
stat -f -c%T now reports the file system type,
and tail -f uses polling for this file system.
'tail' now accepts the --debug option, which is currently used to
detail the --follow implementation being used.
'du' now supports the short option -A corresponding to the existing long
option --apparent-size, for compatibility with FreeBSD.
* Changes in behavior
All commands now markup option names in --help and man pages,
with bold attributes, and hyperlinks into the online manual on gnu.org.
The links can be configured with the --enable-manual-url configure
option,
and the bold highlighting with --disable-bold-man-page-references.
At runtime all markup can be disabled with the TERM=dumb env var value.
'fmt' -w,--width no longer includes '\n' in the width of a line.
I.e., the specified width is interpreted to be an _inclusive_ maximum.
'ls --hyperlink' now uses more standard format hyperlinks.
'ESC\' (ST) is now used as a delimiter, instead of '\a' (BEL).
'ptx' -t is no longer a no-op, and now sets the default width to 100
columns.
'timeout' now honors ignored signals and will not propagate them. E.g.,
timeout(1) in a shell backgrounded job, will not terminate upon
receiving
SIGINT or SIGQUIT, as these are ignored by default in shell background
jobs.
'timeout -v -s 0' now prints the signal number 0 instead of EXIT.
The multi-call binary now only processes --help or --version options
if it is installed with a name ending with "coreutils". This allows
for more consistent handling of these options with unsupported commands.
* Improvements
The multi-call binary built with configure --enable-single-binary
is reduced in size by 3.2% through the more efficient reuse of the cksum
utility by the md5sum and sha*sum utilities.
'cksum' now validates its options more consistently.
E.g., `cksum --text --tag` now fails like `cksum --tag --text` already
did.
'cksum', 'du', and 'wc' now exit promptly upon receiving a write
error, which is significant when processing many input files.
csplit, ls, and sort, now handle a more complete set of terminating
signals.
'du' now processes directories with 10,000 or more entries up to 9 times
faster on the Lustre file system.
'paste' now supports multi-byte --delimiters characters.
'pinky' will now exit immediately upon receiving a write error, which is
significant when reading large plan or project files.
'readlink' and 'realpath' will now exit promptly upon receiving a write
error,
which is significant when canonicalizing multiple file names longer than
PATH_MAX.
'timeout' on Linux will always terminate the child in the case where the
timeout process itself dies, like when it receives a KILL signal for
example.
* Build-related
Programs now port to C23 platforms that strictly check types when
qualifier-generic functions like strchr are used.
'chcon' and 'runcon' stub binaries will be built on systems without
libselinux, when configured using --with-selinux.
'kill' and 'uptime' are no longer built by default. These programs can
be
built with the --enable-install-program=kill,uptime configure option.
