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

* Removed features

  * qemu: Remove support for QEMU < 2.11

    In accordance with our platform support policy, the oldest supported QEMU
    version is now bumped from 1.5 to 2.11.

* New features

  * qemu: Add support for hotplugging ``<transient/>`` disks

    The disk hotplug code in the qemu driver now can handle hotplug of disks
    with automatically added overlay.

  * qemu: Add support for sharing base image of ``<transient/>`` disks

    Users can use ``<transient shareBacking='yes'/>`` to tell the qemu driver to
    never open the base image in write mode thus multiple VMs can share the
    same image. Note that the disk will be hotplugged during startup.

* Improvements

  * Add win-dmp crashdump format

    New ``win-dmp`` format for ``virDomainCoreDumpWithFormat`` API and/or virsh
    ``dump --format`` was introduced.

* Bug fixes

  * Allow 0 offset in XML schema for ``<slice type='storage' offset='0' size='321'/>``

    Having a 0 offset so that the size of the image can be limited is a
    valid configuration so it was allowed in the XML schema.

Enjoy.
