   Updated the failsafe driver including the following changes:
 
-  * Support for Rx queues start and stop.
-  * Support for Rx queues deferred start.
+  * 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 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.**

   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.
