Thanks everybody who helped with this release by sending patches,
reviewing, testing, or providing feedback. Your work is greatly
appreciated.

* New features

  * qemu: Introduce support for ``igb`` network interface model

    ``igb`` is a successor to the ``e1000e`` network device using PCIe interface.
    It was introduced in QEMU 8.0

  * qemu: Improve handling of maximum physical address configuration

* Improvements

  * qemu: Change default machine type for ARM and RISC-V

    ARM and RISC-V architectures now use the ``virt`` machine type by default.
    The previous defaults were nearly unusable and had to be overridden in most
    cases.

  * Improve translatable strings format substitutions

    All translatable error messages with substitution strings were converted to
    use positional modifiers to allow translators to shuffle around words in
    the translation. The translations in Weblate were also updated to match.

  * qemu: Improve validation of ``watchdog`` devices

    Certain invalid configurations of ``watchdog`` device are now properly
    detected:

     - hotplug of always-present platform watchdogs is forbidden
     - ``iTCO`` watchdog can be configured only once
     - ``ib700`` watchdog is allowed only on ``i440fx`` machines

  * Improved output of ``virt-host-validate`` on ARM

    Our validation tool now parses the ``IORT`` data on ARM to properly detect
    presence of SMMU and other features.

* Bug fixes

  * qemu: Fix inactive internal snapshots of VM with UEFI firmware

    Recent changes to UEFI firmware handling resulted into breaking support
    for inactive internal snapshots of VMs with UEFI which historically worked.
    (Although the intention was to disallow them together with active ones, but
    the check did not work properly.)

    Preserve existing functionality by allowing such snapshots explicitly.

  * qemu: Properly configure locked memory limit for VMs with ``<disk type='nvme'``

    The NVMe driver in qemu requires some memory to be locked. This was not
    taken into account in the code which calculates the memory limits based
    on devices present in the configuration

  * Fix native build on win32

    Various improvements to the build system now allow users to build the client
    library of libvirt on win32 natively.

  * qemu: Properly detect tray of hotplugged CD-ROM devices

    Media in a CD-ROM device which was hotplugged could not be changed as the
    presence of the tray was not detected properly on hotplug.

Enjoy.
