+QEMU changes
+~~~~~~~~~~~~
+
+- The ``runqemu`` script no longer systematically adds two serial ports
+ (``--serial null`` and ``-serial mon:stdio``) to the QEMU emulated machine
+ if the user already adds such ports through the ``QB_OPT_APPEND`` setting.
+
+ If the user adds one port, only ``--serial null`` is added, and
+ ``-serial mon:stdio`` is no longer passed. If the user adds more than one
+ port, ``--serial null`` is no longer added either. This can break some
+ existing QEMU based configurations expecting such serial ports to be added
+ when ``runqemu`` is executed.
+
+ This change was made to avoid exceeding two serial ports, which interferes
+ with automated testing.
