+* **Packaging changes**
+
+  * All helper programs are now detected from ``$PATH`` during runtime
+
+    All of the code was now converted to dynamically look up helper programs
+    in ``$PATH`` rather than doing the lookup at build time and then compiling
+    in the result.
+
+    Programs ``mount``, ``umount``, ``mkfs``, ``modprobe``, ``rmmod``,
+    ``numad``, ``dmidecode``, ``ip``, ``tc``, ``mdevctl``, ``mm-ctl``,
+    ``iscsiadm``, ``ovs-vsctl``, ``pkttyagent``, ``bhyveload``, ``bhyvectl``,
+    ``bhyve``, ``ifconfig``, ``vzlist``, ``vzctl``, ``vzmigrate``, and the
+    tools from the lvm suite (``vgchange``, ``lvcreate``, etc..) are now not
+    needed during build and will still work properly if placed in ``$PATH``.
+
+    This also ensures that libvirt works correctly on distros that are
+    transitioning ``/sbin`` into ``/bin`` and upgraded installations have
+    a different layout from fresh installations.

+  * qemu: Treat the ``queues`` configuration of ``virtio-net`` as guest ABI
+
+    The queue count itself isn't a device frontend property but libvirt uses

+    property, thus ``queues`` must not change during migration. The ABI stability
