* **Improvements**
+ * Adapt to qemu's use of protocol drivers in QCOW2 'backing file format' field
+
+ QEMU allows creating images where the 'backing file format' is actually a
+ protocol name such as 'file'/'host_device'/'nbd'/etc.. Adapt libvirt to
+ properly handle such images and don't assume automatic format probing is
+ necessary, which is in many cases forbidden due to security implications.
+
* **Bug fixes**
+ * qemu: Fix setup of images on hotplug of disk
+
+ Internal image metadata was not setup correctly which could cause some disk
+ hotplug configurations (namely those including backing images) to fail.
+
+ * qemu: Fix qemu crash when reverting an internal snapshot
+
+ Libvirt attempted to start qemu with wrong arguments when attempting to
+ revert to an internal snapshot causing qemu to crash.
+
+ * qemu: Fix hotplug of empty cdrom
+
+ Empty cdrom drive couldn't be hotplugged as libvirt wanted to setup the
+ storage backing it unconditionally.
