💖 guestfs-release-notes — libguestfs Release Notes 💖

okay so you're looking at the guestfs-rel...-notes-1.54(1) page, bestie — that's the manual page for guestfs-release-notes, and it's literally just the libguestfs release notes. pull up a chair, we're going through the whole thing 🫶

🌸 RELEASE NOTES FOR LIBGUESTFS 1.54 🌸

These are the release notes for libguestfs stable release 1.54, and they describe the major changes since 1.52. no cap.

Libguestfs 1.54.0 was released on 8 October 2024. mark your calendars 💅

🔍 Inspection

  • Detection of Circle Linux has been added (Bella Zhang). slay.
  • Support for LoongArch has been added (liuxiang). iconic.
  • Detection of Kylin has been added (grass-lu).
  • Detection of openEuler has been added (Wang Guoquan).
  • PARTUUID and PARTLABEL are now resolved in guest /etc/fstab. finally 😭

🧚 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. efficient queen behavior.
  • Support for the following inactive or infrequently used device types has been removed: Gluster, Sheepdog, TFTP. they're gone, bestie 💀
  • The GOST R34.11-94 message digest algorithm has been added to the checksum APIs (Alexey Shabalin).
  • nbd+unix:// URIs (that's NBD over a Unix domain socket, iykyk) are now allowed 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 🫶)
  • The cipher suboption has been added to cryptsetup_open (Jonatan Pålsson).
  • Because of a bug, the part_get_gpt_attributes API could truncate the return value from 64 to 32 bits. This has been fixed. not the 32-bit truncation 💀

🛠️ Build changes

  • btrfs compatibility with kernel changes in Linux 6.7 is fixed.
  • Some compatibility code for versions of util-linux (sfdisk) prior to 2014 has been removed. ancient. bye 👋
  • CFLAGS are now passed through when building the Perl bindings. In particular this means that -g should be passed through correctly, enabling debugging symbols. debug girlies rise 🙌
  • Build on macOS is fixed (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.
  • Generation of the virt-customize --chown parameter is fixed (Yongkui Guo).
  • In the appliance, boot time is reduced when dhcp isn't needed (Olaf Hering). faster boot = main character energy ⚡
  • 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. we love a workaround 💅

🐛 Bugs fixed
