Util-linux 2.32 Release Notes
=============================

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).
