   On supported NICs, we can now setup haipin queue which will offload packets
   from the wire, backto the wire.
 
+* **Added flow tag in rte_flow.**
+
+  SET_TAG action and TAG item have been added to support transient flow tag.
+
+* **Extended metadata support in rte_flow.**
+
+  Flow metadata is extended to both Rx and Tx.
+
+  * Tx metadata can also be set by SET_META action of rte_flow.
+  * Rx metadata is delivered to host via a dynamic field of ``rte_mbuf`` with
+    PKT_RX_DYNF_METADATA.

 * **Updated the enic driver.**
 
   * Added support for Geneve with options offload.

 * ethdev: changed ``rte_eth_dev_owner_delete`` return value from ``void`` to

+  The function ``rte_eth_dev_count_avail`` is a drop-in replacement.
