* **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
* **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.
