Release notes for guestfs tools 1.48

These are the release notes for guestfs tools stable release 1.48. This describes the major changes since 1.46.

Guestfs tools 1.48.0 was released on 14 March 2022.

virt-builder

New templates: "alma-8.5", "centosstream-8", "debian-11", "fedora-34", "fedora-34" (armv7l), "fedora-35" "fedora-35" (aarch64) (Lars Kaiser, Stef Walter).

New fedora-34 (armv7l) template is built to use UEFI.

virt-customize

The yescrypt password hashing method is now supported (Björn Esser).

virt-inspector

Recognise "kalilinux", "kylin" and "msdos" operating systems / Linux distros (Laszlo Ersek).

Inspection of LUKS encrypted filesystems placed directly on logical volumes is now supported, but you will need libguestfs ≥ 1.48 (Laszlo Ersek).

virt-sysprep

Add a new default operation called "net-nmconn" which removes NetworkManager connection profiles (Laszlo Ersek).

virt-win-reg

"virt-win-reg --version" now prints both the version of guestfs tools and the libguestfs library that it is linked with.

Common changes

All OCaml tools now suppress line wrapping when output is redirected to a file (to make it easier to parse logs with external programs). There is a new --wrap option which can be used to re-enable line wrapping to files if needed (Laszlo Ersek).

Build changes

Multiple fixes to make it easier to build against either the system installed libguestfs or a locally built libguestfs (Laszlo Ersek).

Fix multiple OCaml warnings. Remove some deprecated OCaml features. We now require OCaml ≥ 4.04.

Multiple fixes to valgrind support for glibc 2.35, OCaml 4.13 and libvirt 7.7. "make check-valgrind" should now work.

Internals

New OCaml "On_exit" module (from libguestfs-common) is used instead of custom on-exit and signal handling.
