+* **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.
+
+* **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.
+
+* **Added powerpc support in pci probing for vfio-pci devices.**
+
+  sPAPR IOMMU based pci probing enabled for vfio-pci devices.
