* New features

  * qemu: basic support for use of "VFIO variant" drivers

    A VFIO variant driver is a device-specific driver that can
    be used in place of the generic vfio-pci driver, and provides
    extra functionality to support things like live migration of
    guests with vfio-assigned devices. It can currently be used by:

    1) setting ``managed='no'`` in the XML configuration for the device
    2) pre-binding the variant driver using the ``--driver`` option of
       ``virsh nodedev-detach``.

* Bug fixes

  * qemu: Various fixes to firmware selection

    The changes made to firmware selection in libvirt 9.2.0 have unfortunately
    introduced a number of regressions. All known issues in this area have now
    been resolved.

Enjoy.
