   recent distribution kernels will be kept.
+* meson: The minimum supported version of meson for configuring and building
+  DPDK will be increased to v0.47.1 (from 0.41) from DPDK 19.05 onwards. For
+  those users with a version earlier than 0.47.1, an updated copy of meson
+  can be got using the ``pip``, or ``pip3``, tool for downloading python
+  packages.
 * kvargs: The function ``rte_kvargs_process`` will get a new parameter
   for returning key match count. It will ease handling of no-match case.
