+* **Enabled freeing of ring.**
+
+  New function rte_ring_free() allows the user to free a ring
+  if it was created with rte_ring_create().
+
+* **Extended Statistics**
+
+  Define extended statistics naming scheme to store metadata in the name
+  string name of each statistic, refer to the Extended Statistics section
+  of the programmers guide. Implemented the extended stats API for these
+  PMDs:
+
+  * igb
+  * igbvf
+  * i40e
+  * i40evf
+  * fm10k
+  * virtio
+
+* **Added API in ethdev to retrieve RX/TX queue information.**
+
+  *  Add the ability for the upper layer to query RX/TX queue information.
+  *  Add into rte_eth_dev_info new fields to represent information about
+     RX/TX descriptors min/max/align numbers per queue for the device.
+

 * **Added RSS dynamic configuration to bonding.**

+* **i40e: Fixed maximum of 64 queues per port.**
+
+  Fixed the issue in i40e of cannot supporting more than 64 queues per port,
+  though hardware actually supports that. The real number of queues may vary,
+  as long as the total number of queues used in PF, VFs, VMDq and FD does not
+  exceeds the hardware maximum.

+  Fixed issue in hash library where, using multiple cores with
+  hardware transactional memory support, thread scaling did not work,
