guestfs tools release Notes

## NAME

guestfs-tools-release-notes - guestfs tools release Notes

## 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.
