+* The xstats API and rte_eth_xstats struct will be changed to allow retrieval
+  of values without any string copies or parsing.
+  No backwards compatibility is planned, as it would require code duplication
+  in every PMD that supports xstats.
+
 * ABI changes are planned for adding four new flow types. This impacts
   RTE_ETH_FLOW_MAX. The release 2.2 does not contain these ABI changes,
   but release 2.3 will. [postponed]
