+        <description>
+          With QEMU 4.2.0 we can probe for the default CPU model used by QEMU
+          for a particular machine type and store it in the domain XML. This
+          way the chosen CPU model is more visible to users and libvirt will
+          make sure the guest will see the exact same CPU after migration.

+        </summary>
+        <description>
+          QEMU introduced a new way of specifying disks on the command line
+          which enables fine-grained control over the block stack. Libvirt has
+          adapted to this.

+          More patches were merged that replace our internal functions with

+          with GLib functions.

+        <description>
+          Libvirt used Perl scripts to check for coding style, generate some
+          code and things like that. To bring the number of languages used
+          down, these scripts were rewritten into Python.

+        <description>
+          Some distributions still use <code>--with-loader-nvram</code> or
+          <code>nvram</code> variable in qemu.conf. This is now discouraged in
+          favour of FW descriptors. However, instead of silently ignoring user's
+          config, libvirt warns if outdated config is detected.

+        <description>
+          The pconfig feature was enabled in QEMU by accident in 3.1.0. All
+          other newer versions do not support it and it was removed from the
+          Icelake-Server CPU model in QEMU.

+        <description>
+          After sending device hot unplug request to QEMU, libvirt waits up to
+          5 seconds for qemu to confirm the device removal. On some
+          architectures (like PPC64) this can take longer time and libvirt now
+          reflects that.

+        <description>
+          The QEMU driver starts a domain in a namepsace with private
+          <code>/dev</code> and creates only those nodes there which the domain
+          is configured to have. However, it may have happened that if a node
+          changed its minor number this change wasn't propagated to the
+          namespace.

+        <description>
+          If a graphics device was added to XML that had no video device,
+          libvirt automatically added a video device which was always of type
+          'cirrus' on x86_64, even if the underlying qemu didn't support
+          cirrus. Libvirt now bases the decision on qemu's capabilities.
