NAME
       guestfs-release-notes - libguestfs Release Notes

RELEASE NOTES FOR LIBGUESTFS 1.54
       These are the release notes for libguestfs stable release 1.54.  This
       describes the major changes since 1.52.

       Libguestfs 1.54.0 was released on 8 October 2024.

   Inspection
       Add detection of Circle Linux (Bella Zhang).

       Add support for LoongArch (liuxiang).

       Add detection of Kylin (grass-lu).

       Add detection of openEuler (Wang Guoquan).

       "PARTUUID" and "PARTLABEL" are now resolved in guest /etc/fstab.

   API
       New APIs "findfs_partuuid" and "findfs_partlabel".  These can be used
       to efficiently look up a filesystem by its GPT partition UUID or label.

       Support for the following inactive or infrequently used device types
       has been removed: Gluster, Sheepdog, TFTP.

       Add GOST R34.11-94 message digest algorithm to checksum APIs (Alexey
       Shabalin).

       Allow "nbd+unix://" URIs (NBD over Unix domain socket) in guestfish and
       other places.

       Various "part_*" (partition) APIs related to GPT have been
       reimplemented to use util-linux sfdisk instead of sgdisk.  Util-linux
       is more widely available, so this reduces dependencies in the common
       case.  One optional API remains that still uses sgdisk.  (Thanks
       Yongkui Guo).

       Add "cipher" suboption to "cryptsetup_open" (Jonatan Palsson).

       Because of a bug, the "part_get_gpt_attributes" API could truncate the
       return value from 64 to 32 bits.  This has been fixed.

   Build changes
       Fix btrfs compatibility with kernel changes in Linux 6.7.

       Removed some compatibility code for versions of util-linux (sfdisk)
       prior to 2014.

       Pass CFLAGS through when building the Perl bindings.  In particular
       this means that -g should be passed through correctly, enabling
       debugging symbols.

       Fix build on macOS (Antonio Caggiano).

   Internals
       Libguestfs will now no longer recommend using
       "LIBGUESTFS_BACKEND=direct".  This was shown previously when libvirt
       failed to start the appliance.  However it is felt that this now does
       more harm than good.

       Fix generation of virt-customize --chown parameter (Yongkui Guo).

       In the appliance, reduce boot time when dhcp isn't needed (Olaf
       Hering).

       A deadlock in the appliance caused by a regression in Linux 6.11 has
       been worked around.  The deadlock was also fixed in Linux 6.12.

   Bugs fixed
