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

* Security

  * ``CVE-2023-3750``: Fix race condition in storage driver leading to a crash

   In libvirt-8.3 a bug was introduced which in rare cases could cause
   ``libvirtd`` or ``virtstoraged`` to crash if multiple clients attempted to
   look up a storage volume by key, path or target path, while other clients
   attempted to access something from the same storage pool.

* Improvements

  * apparmor: All profiles and abstractions now support local overrides

    This has long been the case for the ``virt-aa-helper`` profile, but has
    now been extended to all other profiles and abstractions. The mechanism
    used is the standard AppArmor 3.x one, where the contents of ``foo`` and
    ``abstractions/foo`` can be overridden by creating ``local/foo`` and
    ``abstractions/foo.d`` respectively.

  * qemu: Support ``removable`` attribute for scsi disk

    Now the scsi disk device (``/disk at device='disk'`` and
    ``/disk/target at bus='scsi'``) supports the ``removable`` attribute at
    ``/disk/target at removable```.

  * qemu: Add NUMA node automatically for memory hotplug

    Users no longer need to specify guest NUMA node in the domain XML when
    enabling memory hotplug, libvirt automatically adds one when it is missing.

  * qemu: Consider ``BeeGFS`` as a shared filesystem

    Allow migration with non-shared storage for VMs accessing storage via
    ``BeeGFS``.

* Bug fixes

  * qemu: Adapt to new way of specifying PC speaker

    PC speaker is now usable again with newer QEMU since the change of how it
    is specified on the command line.

  * qemu_tpm: Try harder to create emulator state

    Libvirt no longer considers empty directory valid SWTPM state and setup is
    now run properly in such case.

Enjoy.
