The 7.10.0 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.

* New features

  * Added virt-pki-query-dn binary

    This binary helps users figure out the format of Distinguished Name
    from a certificate file the way that libvirt expects it in
    tls_allowed_dn_list option of libvirtd.conf configuration file

* Improvements

  * qemu: Report guest interface information in ``virDomainGetGuestInfo``

    Libvirt is now able to report interface information from the guest's
    perspective (using guest agent).

  * qemu: detect guest side errors during device removal

    Libvirt is now able to detect guest side errors during device removal by
    using the DEVICE_UNPLUG_GUEST_ERROR event, available in QEMU 6.2.0.

  * Minimum SSF setting

    The libvirtd.conf option tcp_min_ssf can be used to override the minimum
    permitted security strength factor for non-TLS remote connections.
    The current hardcoded minimum is 56 (single-DES) and will be raised to 112
    in the future. Setting a minimum lower than 112 is not supported.

  * qemu: Report stats also for block copy destination and backup job scratch
    images

    The statistics are available via the bulk domain stats API.

* Bug fixes

  * qemu: Don't format 'ramfb' attribute when disabled

    Fix a regression caused by the conversion to JSON -device arguments where
    'ramfb' would be put on the commandline of 'vfio-pci' which doesn't have it,
    thus breaking VMs with a mediated host device.

  * qemu: Fix block copy and backup to encrypted storage

    An oversight in last release lead to a spurious error being reported when
    encrypted storage was requested for disk images which are not directly
    backing the disk, which is now fixed.

Enjoy.
