=========================================================
+* **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.
+
* **Updated Mellanox mlx5 driver.**
Updated Mellanox mlx5 driver with new features and improvements, including:
* Added support for matching on IPv4 Time To Live and IPv6 Hop Limit.
+ * Added support for creating Relaxed Ordering Memory Regions.
+ * Added support for jumbo frame size (9K MTU) in Multi-Packet RQ mode.
+ * Optimized the memory consumption of flow.
+
+* **Updated the AESNI MB crypto PMD.**
+
+ * Added support for intel-ipsec-mb version 0.54.
+ * Updated the AESNI MB PMD with AES-256 DOCSIS algorithm.
+ * Added support for synchronous Crypto burst API.
-* **Added event mode to ipsec-secgw application.**
+* **Updated the AESNI GCM crypto PMD.**
- Updated ipsec-secgw application to add event based packet processing. The worker
- thread(s) would receive events and submit them back to the event device after
- the processing. This way, multicore scaling and HW assisted scheduling is achieved
- by making use of the event device capabilities. The event mode currently supports
- only inline IPsec protocol offload.
+ * Added support for intel-ipsec-mb version 0.54.
+
+* **Added a new driver for Intel Foxville I225 devices.**
+
+ Added the new ``igc`` net driver for Intel Foxville I225 devices. See the
+ :doc:`../nics/igc` NIC guide for more details on this new driver.
+
+* **Updated Broadcom bnxt driver.**
+
+ Updated Broadcom bnxt driver with new features and improvements, including:
+
+ * Added support for host based flow table management
+ * Added flow counters to extended stats
+ * Added PCI function stats to extended stats
+
+* **Added handling of mixed crypto algorithms in QAT PMD for GEN2.**
+
+ Enabled handling of mixed algorithms in encrypted digest hash-cipher
+ (generation) and cipher-hash (verification) requests in QAT PMD
+ when running on GEN2 QAT hardware with particular firmware versions
+ (GEN3 support was added in DPDK 20.02).
+
+* **Added plain SHA-1,224,256,384,512 support to QAT PMD.**
+
+ Added support for plain SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512 hashes
+ to QAT PMD.
+
+* **Added QAT intermediate buffer too small handling in QAT compression PMD.**
+
+ Added a special way of buffer handling when internal QAT intermediate buffer
+ is too small for Huffman dynamic compression operation. Instead of falling
+ back to fixed compression, the operation is now split into multiple smaller
+ dynamic compression requests (possible to execute on QAT) and their results
+ are then combined and copied into the output buffer. This is not possible if
+ any checksum calculation was requested - in such case the code falls back to
+ fixed compression as before.
+
+* **Updated the turbo_sw bbdev PMD.**
+
+ Supported large size code blocks which does not fit in one mbuf segment.
+
+* **Added Intel FPGA_5GNR_FEC bbdev PMD.**
+
+ Added a new ``fpga_5gnr_fec`` bbdev driver for the Intel\ |reg| FPGA PAC
+ (Programmable Acceleration Card) N3000. See the
+ :doc:`../bbdevs/fpga_5gnr_fec` BBDEV guide for more details on this new driver.
+
+* **Updated ipsec-secgw sample application with following features.**
+
+ * Updated ipsec-secgw application to add event based packet processing.
+ The worker thread(s) would receive events and submit them back to the
+ event device after the processing. This way, multicore scaling and HW
+ assisted scheduling is achieved by making use of the event device
+ capabilities. The event mode currently supports only inline IPsec
+ protocol offload.
+
+ * Updated ipsec-secgw application to support key sizes for AES-192-CBC,
+ AES-192-GCM, AES-256-GCM algorithms.
+
+ * Added IPsec inbound load-distribution support for ipsec-secgw application
+ using NIC load distribution feature(Flow Director).
+
+* **Added rte_graph library.**
+
+ Graph architecture abstracts the data processing functions as a ``node`` and
+ ``links`` them together to create a complex ``graph`` to enable reusable/modular
+ data processing functions. The graph library provides API to enable graph
+ framework operations such as create, lookup, dump and destroy on graph and node
+ operations such as clone, edge update, and edge shrink, etc.
+ The API also allows to create the stats cluster to monitor per graph and per node stats.
+
+* **Added rte_node library which consists of a set of packet processing nodes.**
+
+ The rte_node library that consists of nodes used by rte_graph library. Each
+ node performs a specific packet processing function based on application
+ configuration. The following nodes are added:
+
+ * Null node: Skeleton node that defines the general structure of a node.
+ * Ethernet device node: Consists of ethernet Rx/Tx nodes as well as ethernet
+ control APIs.
+ * IPv4 lookup node: Consists of ipv4 extract and lpm lookup node. Routes can
+ be configured by the application through ``rte_node_ip4_route_add`` function.
+ * IPv4 rewrite node: Consists of ipv4 and ethernet header rewrite functionality
+ that can be configured through ``rte_node_ip4_rewrite_add`` function.
+ * Packet drop node: Frees the packets received to their respective mempool.
+
+* **Added new l3fwd-graph sample application.**
+
+ Added an example application ``l3fwd-graph``. It demonstrates the usage of graph
+ library and node library for packet processing. In addition to the library usage
+ demonstration, this application can use for performance comparison with existing
+ ``l3fwd`` (The static code without any nodes) with the modular ``l3fwd-graph``
+ approach.

=========================================================
+* mempool: The API of ``rte_mempool_populate_iova()`` and
+ ``rte_mempool_populate_virt()`` changed to return 0 instead of -EINVAL
+ when there is not enough room to store one object.
