RELEASE NOTES FOR GUESTFS TOOLS 1.54
These are the release notes for guestfs tools stable release 1.54. This describes the major changes since 1.52.

Guestfs tools 1.54.0 was released on 21st May 2025.

  New repository location
The upstream git repository is now: https://github.com/libguestfs/guestfs-tools

  virt-customize
New --inject-blnsvr which can be used to inject the Windows memory balloon server into guests.

--inject-virtio-win no longer supports the "osinfo" method (use libosinfo for virtio-win driver information), as it is no longer maintained and had got quite out of date. The default method using virtio-win directory names is more reliable and preferred in all instances (Cole Robinson).

  virt-drivers
Handle large output of the rpm(1) command when listing drivers in some SUSE guests.

  virt-make-fs
Use the file(1) -S option to disable seccomp protection when we also use the file(1) -z option, as the two options are incompatible and cause crashes on some Linux distros.

  virt-resize
Correct the calculation of the target disk. In some cases with the --resize option it was not calculated correctly and partition creation on the target would fail with a confusing error.

We now use stderr consistently for debug messages.

  Common changes
Add support for LoongArch (liuxiang from Loongson).

Fix OCaml bytecode builds (Jerry James, Ilya Leoshkevich).

Allow "nbd+unix://" URIs in -a parameters to several tools.

Add a git-publish profile (Kashyap Chamarthy).

  Build changes
json-c is now required. This replaces Jansson which was previously used for parsing JSON input files.

OCaml ≥ 4.08 is now required.

OCaml oUnit is no longer used.

We now assume that "__attribute__((cleanup))" always works. This requires gcc or Clang.

Add support for GCC 14 and 15.

Some deprecated autoconf macros are no longer used.

Fix some issues when building on macOS (Mohamed Akram).

  Internals
The tests were modified to use a set of common functions and remove use of the weird $TEST_FUNCTIONS macro, similar to how we do it in nbdkit.

Some internal OCaml List and String functions that we used have been replaced by ones from the OCaml stdlib, reducing code maintenance.

Fix compatibility with GNU gettext 0.25.
