[Jiri Denemark]

The 8.6.0 release of both libvirt and libvirt-python is tagged and
signed tarballs and source RPMs are available at

    https://libvirt.org/sources/
    https://libvirt.org/sources/python/

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

* Improvements

  * conf: Improved firmware autoselection

    The firmware autoselection feature now behaves more intuitively, reports
    better error messages on failure and comes with high-level documentation.

Enjoy.
