[Util-linux 2.32 Release Notes][1]:

> Release highlights
> ------------------
>
> The command cal(1) has been improved to provide better control on used calendar
> system. Now it is possible to switch between Gregorian and Julian exclusively,
> or use the current default (reform in September 1752). The new command line
> options --reform and --iso have been added. The command also follows terminal
> width to format output.
>
> The library libblkid has been extended to support LUKS2, Micron mpool, VDO and
> Atari partition table.
>
> The command rfkill(8) has been moved to /usr/sbin to be compatible with the
> original rfkill implementation.
>
> The command dmesg(1) provides better support for multi-line messages and the
> new command line option --force-prefix to print facility, level or timestamp
> information to each line of a multi-line message
>
> The command fallocate(1) --dig-holes is faster and more effect now.
>
> The command fdisk(8) provides access to Protective MBR accessible from main
> menu. The Sun label support has been improved.
>
> The command lscpu(1) provides more details about ARM CPUs now.
>
> The command lsmem(1) supports memory zone awareness now.
>
> The command lsns(8) provides netnsid and nsfs columns now.
>
> The command rtcwake(8) waits stdin to settle down before entering a system
> sleep.
>
> The new command line option --kill-child has been added to unshare(1).

[Util-linux 2.33 Release Notes][2]:

> Release highlights
> ------------------
>
> choom -- NEW COMMAND to adjust and display the current OOM-killer score.
>
> The library libsmartcols has been improved to differentiate between numbers,
> booleans and strings in JSON output. The old versions uses strings everywhere.
> It's recommended to re-test your applications if you parse JSON outputs from
> util-linux tools.
>
> The command fstrim(8) has been extended to trim all mounted filesystems from
> /etc/fstab (-A|--fstab). This semantic is the default for systemd
> fstrim.service now.  The original default for the service was to trim all
> (-a|--all) mounted filesystems (including for example removable media). Now it
> is also possible to test fstrim behavior by new command line option --dry-run.
>
> The command hwclock(8) provides a new command line option --delay to overwrite
> internally used delay when set clock time. The default is 0.5 (500ms) for
> rtc_cmos, for another RTC types the delay is 0. If RTC type is impossible to
> determine (from sysfs) then it defaults also to 0.5 to be backwardly
> compatible. The 500ms default is based on commonly used MC146818A-compatible
> (x86) hardware clock.
>
> The commands mount and umount, and libmount allow to mount and umount
> filesystem in another namespace. The namespace may be specified by --namespace
> <pid|path> command line option. The commands switch to the namespace when it
> reads /etc/fstab, writes /etc/mtab (or writes to /run/mount) and calls [u]mount
> system calls, otherwise it runs in the original namespace. It means that the
> target namespace does not have to contain any libraries or another requirements
> necessary to execute mount(8) or umount(8) commands.
>
> The command rename(1) provides a new command line option --interactive to ask
> before overwriting.
>
> The command setarch(8) does not require architecture when modify personality like
> ADDR_NO_RANDOMIZE. The architecture argument is optional now.
>
> The command su(1) provides a new command line option --whitelist-environment to
> protect specified variables when su(1) starts a new session.
>
> The command setpriv(1) provides a new command line option --reset-env to reset
> all environment. The another new command line option --pdeathsig allows to
> keep, clear or or set the parent death signal. Note that some LSMs, most notably
> SELinux and AppArmor, clear the signal when the process' credentials change.
>
> The commands fdisk(8) and sfdisk(8) print disk model name to simplify device
> identification.
>
> The command "column --table-empty-lines" allows to use empty lines in formatted
> output.
>
> The command wipefs has been improved to postpone BLKRRPART (re-read partition
> table) ioctl until all magic strings are wiped. This semantic allows to avoid
> conflicts between on partition magic strings and partition tables.
>
> The command script(1) has been extended to store more information about
> terminal size and type to the typescript header. The size of the output may be
> also restricted by a new command line option --output-limit.
>
> The libblkid provides BitLocker and basic APFS detection now.
>
> The command lsblk is possible to execute against /sys and /proc dumps if command
> line option --sysroot is specified. This allows to prepare regression tests for
> lsblk.  So, if you have a complicated or unusual setup (RAIDs, pools, etc) than
> you can use
>   https://raw.githubusercontent.com/karelzak/util-linux/master/tests/ts/lsblk/mk-input.sh
> to generate the dump and send the tarball to upstream developers. (Thanks!)
>
>
> The script ./configure has been improved and --with/without command line
> options should be more consistent now. It's recommended to re-test your build
> scripts.
