   * 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.

   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
