+        <description>
+          When a domain is starting up libvirt changes DAC and
+          SELinux labels so that domain can access it. However,
+          it never remembered the original labels and therefore
+          the file was returned back to <code>root:root</code>.
+          With this release, the original labels are remembered
+          and restored properly.

+          This works similarly to the existing support for passing arbitary

+          support guarantees.

+          nss: Report newer addresses first
+        </summary>
+        <description>
+          In some cases, a guest might be assigned a new IP address by DHCP
+          before the previous lease has expired, in which case the NSS plugin
+          will correctly report both addresses; many applications, however,
+          ignore all addresses but the first, and may thus end up trying to
+          connect using a stale address. To prevent that from happening, the
+          NSS plugin will now always report the newest address first.

+        </summary>
+        <description>
+          When the limit on the number of FDs is very high, closing all
+          unwanted FDs after calling <code>fork()</code> can take a lot of
+          time and delay the start of the child process. libvirt will now
+          use an optimized algorithm that minimizes such delays.

+        <description>
+          virtlogd implements its own rollover mechanism, but until now
+          logrotate could end up acting on the logs before virtlogd had a
+          chance to do so itself.
