RELEASE NOTES FOR LIBGUESTFS 1.48

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

       Libguestfs 1.48.0 was released on 14 March 2022.

   Some features removed
       The following little used, experimental or unsafe features have been removed:

       "Libguestfs live" was an experimental feature that allowed you (in theory) to connect to
       an existing instance of the libguestfs daemon in a running guest.  If you want to do this
       we recommend installing qemu-guest-agent in the guest instead and using the APIs provided
       by it.  The related "unix:" backend has been removed.  The guestfish(1) and guestmount(1)
       --live option now prints an error.

       The User-mode Linux ("uml") backend has been removed.  It was an alternate hypervisor that
       could be used instead of qemu.  It had many limitations including lack of network support,
       and lack of qemu native features like qcow2 or network-backed disks.  In addition it was
       slower than KVM and particular features like bulk upload/download were painfully slow.
       Also the UML feature of Linux that it was based on often does not work.

       The 9pfs APIs "guestfs_list_9p" and "guestfs_mount_9p" have been deprecated and now return
       errors.  This was related to an experimental feature for passing through host filesystems
       to the appliance.  You had to hand-hack the qemu command line for this to work and it did
       not fit the libguestfs model very well.

       "guestfs_add_drive" no longer supports hotplugging (adding a drive after launch), and
       "guestfs_remove_drive" has been deprecated and now returns an error.  Hotplugging was an
       unsuccessful feature which was complicated to implement and maintain, and was slow and
       insecure.  It also only worked with the non-default libvirt backend, and was never
       implemented in the default "direct" backend.

   Language bindings
       Fix allocation and deallocation of string lists in golang bindings (Laszlo Ersek).

       Multiple fixes to the OCaml bindings: Fix warnings, move minimum version to OCaml 4.04,
       replace various deprecated OCaml features with modern OCaml features.

       Running "make distclean" in the rust directory now completely cleans the cargo temporary
       files.

   Inspection
       Fix inspection of modern Pardus GNU/Linux (Laszlo Ersek).

       Add support for Kylin (Laszlo Ersek).

       Add support for Rocky Linux (Neil Hanlon).

       Inspection of guests which use LUKS encryption on top of LVM logical volumes should now
       work (Laszlo Ersek).

   API
       New APIs

       No new APIs were added in libguestfs 1.48.

       Other API changes

       "guestfs_list_9p" and "guestfs_mount_9p" are deprecated and now return errors.

       "guestfs_remove_drive" has been deprecated and now returns an error.

       In "guestfs_xfs_admin" the "lazycounter" parameter is deprecated because it is no longer
       supported in recent versions of XFS.

       Partition APIs now cope with the broken MBR partition tables created by dosfstools ≥ 4.2
       (Laszlo Ersek).

       In "guestfs_md_create" the "chunk" parameter should not be used with RAID 1.  Previously
       it was allowed but ignored, but now it will give an error (Laszlo Ersek).

   Build changes
       Multiple compiler warnings fixed and/or analyzed and suppressed (Laszlo Ersek).

       Fix detection of optional Yara library using pkg-config instead of checking for
       library/header file (Laszlo Ersek).

       Update valgrind suppressions for glibc 2.35, OCaml 4.13 and libvirt 7.7.  "make
       check-valgrind" works again.

       If using libvirt ≥ 3.8.0, we now use <interface> to create the appliance network interface
       instead of adding qemu command line parameters (Laszlo Ersek).

       The guestfs-release-notes(1) page was a broken link, but it has now been restored as a new
       page that links to the release notes from each stable release.

   Internals
       The libc API strerror_r(3) is difficult to use correctly because of differing signatures
       in glibc and other libc.  A wrapper "guestfs_int_strerror" has been created to hide the
       differences.
