   * Match items: destination MAC address.
   * Action items: push/pop/rewrite vlan header.
 
+* **Added a devarg to use the latest supported vector path in i40e.**
+  A new devarg ``use-latest-supported-vec`` was introduced to allow users to
+  choose the latest vector path that the platform supported. For example, users
+  can use AVX2 vector path on BDW/HSW to get better performance.
+
 * **Added support for SR-IOV in netvsc PMD.**
 
   The ``netvsc`` poll mode driver now supports the Accelerated Networking
   SR-IOV option in Hyper-V and Azure. This is an alternative to the previous
   vdev_netvsc, tap, and failsafe drivers combination.
 
+* **Updated failsafe driver.**
+
+  Updated the failsafe driver including the following changes:
+
+  * Support for Rx and Tx queues start and stop.
+  * Support for Rx and Tx queues deferred start.
+  * Support for runtime Rx and Tx queues setup.
+  * Support multicast MAC address set.
+
+* **Added Event Ethernet Tx Adapter.**
+
+  Added event ethernet Tx adapter library that  provides configuration and
+  data path APIs for the ethernet transmit stage of an event driven packet
+  processing application. These APIs abstract the implementation of the
+  transmit stage and allow the application to use eventdev PMD support or
+  a common implementation.
+
+* **Added Distributed Software Eventdev PMD.**
+
+  Added the new Distributed Software Event Device (DSW), which is a
+  pure-software eventdev driver distributing the work of scheduling
+  among all eventdev ports and the lcores using them. DSW, compared to
+  the SW eventdev PMD, sacrifices load balancing performance to
+  gain better event scheduling throughput and scalability.
+
+* **Added ability to switch queue deferred start flag on testpmd app.**
+
+  Added a console command to testpmd app, giving ability to switch
+  ``rx_deferred_start`` or ``tx_deferred_start`` flag of the specified queue of
+  the specified port. The port must be stopped before the command call in order
+  to reconfigure queues.

    =========================================================
 
+* mbuf: The ``__rte_mbuf_raw_free()`` and ``__rte_pktmbuf_prefree_seg()``
+  functions were deprecated since 17.05 and are replaced by
+  ``rte_mbuf_raw_free()`` and ``rte_pktmbuf_prefree_seg()``.
+
 * A new device flag, RTE_ETH_DEV_NOLIVE_MAC_ADDR, changes the order of
   actions inside rte_eth_dev_start regarding MAC set. Some NICs do not
   support MAC changes once the port has started and with this new device
   flag the MAC can be properly configured in any case. This is particularly
   important for bonding.
 
+* The default behaviour of CRC strip offload changed. Without any specific Rx
+  offload flag, default behavior by PMD is now to strip CRC.
+  DEV_RX_OFFLOAD_CRC_STRIP offload flag has been removed.
+  To request keeping CRC, application should set ``DEV_RX_OFFLOAD_KEEP_CRC`` Rx
+  offload.
