.SH "RELEASE NOTES FOR LIBGUESTFS 1.52"
.IX Header "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.
.PP
Libguestfs 1.52.0 was released on \fB5 January 2024\fR.
.SS "Language bindings"
.IX Subsection "Language bindings"
The Python bindings now use \f(CW\*(C`bytes\*(C'\fR (instead of \f(CW\*(C`str\*(C'\fR) for the event
callback message, since it may contain arbitrary 8 bit data (thanks
Yonatan Shtarkman).
.PP
Also in the Python bindings, fix a rare crash, and avoid memory leaks
in event callbacks (thanks Yonatan Shtarkman, Laszlo Ersek, Eric
Blake).
.PP
Support for OCaml 5, and OCaml ≥ 4.07 is now the minimum (thanks
Guillaume Munch-Maccagnoni, Jerry James, Josh Berdine, Jürgen Hötzel,
Vincent Laviron).
.PP
The OCaml bindings now release the runtime lock around calls to
\&\f(CW\*(C`guestfs_close\*(C'\fR, since that call might be long-running (for example
it might have to shut down the appliance and synch disks).
.SS Inspection
.IX Subsection "Inspection"
Support OpencloudOS (cunshunxia@tencent).
.SS API
.IX Subsection "API"
SELinux relabelling now runs in parallel, meaning it's a lot quicker
(Andrey Drobyshev).
.PP
Add support for lzma and zstd compression methods in tar APIs (like
\&\f(CW\*(C`guestfs_tar_in\*(C'\fR) (Zixun LI).
.PP
\&\f(CW\*(C`guestfs_pvs_full\*(C'\fR previously didn't always return the correct device
names.  This has now been fixed.
.PP
\&\f(CW\*(C`guestfs_btrfs_filesystem_balance\*(C'\fR fixed so it now works with more
modern btrfs tools (Jürgen Hötzel).
.SS Tools
.IX Subsection "Tools"
The \fBguestfish\fR\|(1) \fI\-\-key\fR option now recognizes LVM names like
\&\fI/dev/mapper/rhel_bootp\-\-73\-\-75\-\-123\-root\fR (Laszlo Ersek).
.PP
guestfish \fI\-\-key\fR option also supports a new \fI\-\-key\ all:...\fR
selector to try the same key on all devices.
.PP
In \fBguestmount\fR\|(1) avoid calling \f(CWfclose(NULL)\fR on error paths,
which might have caused a crash on some platforms.
.SS "Build changes"
.IX Subsection "Build changes"
The \f(CW\*(C`RELEASES\*(C'\fR file (which listed release dates) has been removed and
replaced with a simple \f(CW\*(C`RELEASE_DATE\*(C'\fR macro in \fI./configure\fR.  This
should simplify builds.
.PP
Optionally \fBpasst\fR\|(1) may be used for networking (Laszlo Ersek).
.PP
\&\fBdhcpcd\fR\|(8) is now used in preference to dh-client on Red Hat
platforms.
.PP
Old Ruby \f(CW\*(C`MiniTest\*(C'\fR and \f(CW\*(C`Test::Unit\*(C'\fR dependencies replaced with new
\&\f(CW\*(C`Minitest\*(C'\fR.
.PP
Fix compatibility issues with libxml2 2.12.
.SS Internals
.IX Subsection "Internals"
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.
.PP
Fix a segmentation fault when \f(CW\*(C`TERM\*(C'\fR environment variable was set to
\&\f(CW\*(C`dumb\*(C'\fR (Daisuke HATAYAMA).
.PP
Avoid a warning on modern Fedora which does not have \fI/selinux\fR
(Andrey Drobyshev).
.PP
Fix build on OpenSUSE LEAP 15 or other distros with a \fBfile\fR\|(1)
command which did not understand the \fI\-S\fR option (thanks Olaf
Hering).
