=item CVE-2022-2211

L<https://bugzilla.redhat.com/show_bug.cgi?id=2100862>

A buffer overflow was found in the I<--key> option of several guestfs
tools.  For more information on this low severity bug see the bug
report above (Laszlo Ersek).

=head2 New virt-drivers tool

This new tool can examine a disk image to determine:

=over 4

=item *

Whether it uses BIOS or UEFI for booting

=item *

What bootloader it uses (Linux only)

=item *

What kernels may be chosen at boot time (Linux only)

=item *

What device drivers (kernel modules) are installed

=back

This is useful for determining how (or if) a guest can boot on a
virtualization hypervisor.

=head2 virt-customize

I<--selinux-relabel> is now the default for SELinux guests.  You no
longer need to specify this flag.  In the rare case where you don't
want to relabel a guest after customizing it, you can use
I<--no-selinux-relabel>.  Note this is not needed for non-SELinux
guests, it will do the right thing automatically (Laszlo Ersek).

New I<--inject-qemu-ga> and I<--inject-virtio-win> operations which
respectively inject QEMU Guest Agent and virtio-win drivers into
Windows guests.

Rocky Linux guests are now supported (thanks Harry Benson).

=head2 virt-inspector

Virt-inspector now outputs the new E<lt>build_idE<gt> element
containing the guest build ID, if using libguestfs E<ge> 1.50.

=head2 virt-sysprep

New C<lvm-system-devices> operation for removing LVM2's
F<system.devices> file.  This avoids certain problems when cloning a
VM (Laszlo Ersek).

Virt-sysprep supports guests using LUKS logical volumes on top of LVM
(Laszlo Ersek).

=head2 Common changes

All the tools supporting the I<--key> option can now use Clevis/Tang
to decrypt full disk encryption using this network-based scheme
(Laszlo Ersek).

=head2 Build changes

B<Note> that libguestfs now requires minimum OCaml 4.04.  It will not
compile on RHEL 6.

B<Note> that libosinfo is a new required dependency.

OCaml 4.14 is now supported.

C<./configure --disable-ocaml> and C<./configure --disable-perl> now
disable the OCaml- and Perl-based tools respectively (thanks Simon
Walter).

Experimental support for compiling on macOS.

When running C<make check-valgrind>, Valgrind logs are no longer
written to separate files under F<tmp/>.  Instead the output is
written to the normal F<I<test-name>.log> file.
