+* **Added free Tx mbuf on demand API.**
+
+ Added a new function ``rte_eth_tx_done_cleanup()`` which allows an application
+ to request the driver to release mbufs from their Tx ring that are no longer
+ in use, independent of whether or not the ``tx_rs_thresh`` has been crossed.
+
+* **Added descriptor status ethdev API.**
+
+ Added a new API to get the status of a descriptor.
+
+ For Rx, it is almost similar to the ``rx_descriptor_done`` API, except
+ it differentiates descriptors which are hold by the driver and not
+ returned to the hardware. For Tx, it is a new API.
+
+* **Increased number of next hops for LPM IPv6 to 2^21.**
+
+ The next_hop field is extended from 8 bits to 21 bits for IPv6.
