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

* Security

  * qemu: Enable client TLS certificate validation by default for ``chardev``,
    ``migration``, and ``backup`` servers.

  The default value if qemu.conf options ``chardev_tls_x509_verify``,
  ``migrate_tls_x509_verify``, or  ``backup_tls_x509_verify`` are not specified
  explicitly in the config file and also the ``default_tls_x509_verify`` config
  option is missing are now '1'. This ensures that only legitimate clients
  access servers, which don't have any additional form of authentication.

* New features

  * qemu: Implement OpenSSH authorized key file management APIs

    New APIs (``virDomainAuthorizedSSHKeysGet()`` and
    ``virDomainAuthorizedSSHKeysSet()``) and virsh commands
    (``get-user-sshkeys`` and ``set-user-sshkeys``) are added to manage
    authorized_keys SSH file for user.

  * hyperv: implement new APIs

    The ``virDomainGetMaxMemory()``, ``virDomainSetMaxMemory()``,
    ``virDomainGetSchedulerType()``, ``virDomainGetSchedulerParameters()``,
    ``virDomainGetSchedulerParametersFlags()``, ``virDomainGetVcpus()``,
    ``virDomainGetVcpusFlags()``, ``virDomainGetMaxVcpus()``,
    ``virDomainSetVcpus()``, and ``virDomainSetVcpusFlags()`` APIs have been
    implemented in the Hyper-V driver.

* Improvements

  * virsh: Support network disks in ``virsh attach-disk``

    The ``virsh attach-disk`` helper command which simplifies attaching of disks
    without the need for the user to formulate the disk XML manually now
    supports network-backed images. Users can specify the protocol and host
    specification with new command line arguments. Please refer to the man
    page of virsh for further information.

* Bug fixes

  * remote: fixed performance regression in SSH tunnelling

    The ``virt-ssh-helper`` binary introduced in 6.8.0 had very
    poor scalability which impacted libvirt tunnelled migration
    and storage volume upload/download in particular. It has been
    updated and now has performance on par with netcat.

* Removed features

  * hyperv: removed support for the Hyper-V V1 WMI API

    This drops support for Windows Server 2008R2 and 2012.
    The earliest supported version is now Windows 2012R2.

Enjoy.
