+* **Added Trace Library and Tracepoints**
+
+ A native implementation of ``common trace format(CTF)`` based trace library
+ has been added to provide the ability to add tracepoints in
+ application/library to get runtime trace/debug information for control and
+ fast APIs with minimum impact on fast path performance.
+ Typical trace overhead is ~20 cycles and instrumentation overhead is 1 cycle.
+ Added tracepoints in ``EAL``, ``ethdev``, ``cryptodev``, ``eventdev`` and
+ ``mempool`` libraries for important functions.
+
+* **Added new API for rte_ring.**
+
+ * New synchronization modes for rte_ring.
+
+ Introduced new optional MT synchronization modes for rte_ring:
+ Relaxed Tail Sync (RTS) mode and Head/Tail Sync (HTS) mode.
+ With these mode selected, rte_ring shows significant improvements for
+ average enqueue/dequeue times on overcommitted systems.
+
+ * Added peek style API for rte_ring.
+
+ For rings with producer/consumer in RTE_RING_SYNC_ST, RTE_RING_SYNC_MT_HTS
+ mode, provide an ability to split enqueue/dequeue operation into two phases
+ (enqueue/dequeue start; enqueue/dequeue finish). That allows user to inspect
+ objects in the ring without removing them from it (aka MT safe peek).
+
+* **Added flow aging support.**
+
+ Added flow aging support to detect and report aged-out flows, including:
+
+ * Added new action: ``RTE_FLOW_ACTION_TYPE_AGE`` to set the timeout
+ and the application flow context for each flow.
+ * Added new event: ``RTE_ETH_EVENT_FLOW_AGED`` for the driver to report
+ that there are new aged-out flows.
+ * Added new query: ``rte_flow_get_aged_flows`` to get the aged-out flows
+ contexts from the port.
+
+* **Updated Amazon ena driver.**
+
+ Updated ena PMD with new features and improvements, including:
+
+ * Added support for large LLQ (Low-latency queue) headers.
+ * Added Tx drops as new extended driver statistic.
+ * Added support for accelerated LLQ mode.
+ * Handling of the 0 length descriptors on the Rx path.
+
+* **Updated Intel i40e driver.**
+
+ Updated i40e PMD with new features and improvements, including:
+
+ * Enable MAC address as FDIR input set for ipv4-other, ipv4-udp and ipv4-tcp.
+ * Added support for RSS using L3/L4 source/destination only.
+ * Added support for setting hash function in rte flow.
+
+* **Updated the Intel iavf driver.**
+
+ Update the Intel iavf driver with new features and improvements, including:
+
+ * Added generic filter support.
+ * Added advanced iavf with FDIR capability.
+ * Added advanced RSS configuration for VFs.
+
+* **Updated the Intel ice driver.**
+
+ Updated the Intel ice driver with new features and improvements, including:
+
+ * Added support for DCF (Device Config Function) feature.
+ * Added switch filter support for intel DCF.
+
+* **Updated Marvell OCTEON TX2 ethdev driver.**
+
+ Updated Marvell OCTEON TX2 ethdev driver with traffic manager support with
+ below features.
+
+ * Hierarchial Scheduling with DWRR and SP.
+ * Single rate - Two color, Two rate - Three color shaping.
