=head1 RELEASE NOTES FOR LIBGUESTFS 1.52

These are the release notes for libguestfs stable release 1.52.  This describes the major changes since 1.50.

Libguestfs 1.52.0 was released on B<5 January 2024>.

=head2 Прив’язки до мов програмування

The Python bindings now use C<bytes> (instead of C<str>) for the event callback message, since it may contain arbitrary 8 bit data (thanks Yonatan Shtarkman).

Also in the Python bindings, fix a rare crash, and avoid memory leaks in event callbacks (thanks Yonatan Shtarkman, Laszlo Ersek, Eric Blake).

Support for OCaml 5, and OCaml E<ge> 4.07 is now the minimum (thanks Guillaume Munch-Maccagnoni, Jerry James, Josh Berdine, Jürgen Hötzel, Vincent Laviron).

The OCaml bindings now release the runtime lock around calls to C<guestfs_close>, since that call might be long-running (for example it might have to shut down the appliance and synch disks).

=head2 Перевірка

Support OpencloudOS (cunshunxia@tencent).

=head2 API

SELinux relabelling now runs in parallel, meaning it's a lot quicker (Andrey Drobyshev).

Add support for lzma and zstd compression methods in tar APIs (like C<guestfs_tar_in>) (Zixun LI).

C<guestfs_pvs_full> previously didn't always return the correct device names.  This has now been fixed.

C<guestfs_btrfs_filesystem_balance> fixed so it now works with more modern btrfs tools (Jürgen Hötzel).

=head2 Інструменти

The L<guestfish(1)> I<--key> option now recognizes LVM names like F</dev/mapper/rhel_bootp--73--75--123-root> (Laszlo Ersek).

guestfish I<--key> option also supports a new S<I<--key all:...>> selector to try the same key on all devices.

In L<guestmount(1)> avoid calling C<fclose(NULL)> on error paths, which might have caused a crash on some platforms.

=head2 Зміни у збиранні

The C<RELEASES> file (which listed release dates) has been removed and replaced with a simple C<RELEASE_DATE> macro in F<./configure>.  This should simplify builds.

Optionally L<passt(1)> may be used for networking (Laszlo Ersek).

L<dhcpcd(8)> is now used in preference to dh-client on Red Hat platforms.

Old Ruby C<MiniTest> and C<Test::Unit> dependencies replaced with new C<Minitest>.

Fix compatibility issues with libxml2 2.12.

=head2 Внутрішня частина роботи програми

On x86-64 we now use the more modern q35 machine type when running the appliance.  This should perform slightly better and has more development attention from the qemu community.  The change should be invisible to libguestfs users.

Fix a segmentation fault when C<TERM> environment variable was set to C<dumb> (Daisuke HATAYAMA).

Avoid a warning on modern Fedora which does not have F</selinux> (Andrey Drobyshev).

Fix build on OpenSUSE LEAP 15 or other distros with a L<file(1)> command which did not understand the I<-S> option (thanks Olaf Hering).
