+* **Added write combining store APIs.**
+
+  Added ``rte_write32_wc`` and ``rte_write32_wc_relaxed`` APIs
+  that enable write combining stores (depending on architecture).
+  The functions are provided as a generic stubs and
+  x86 specific implementation.
+
+* **Updated CRC modules of the net library.**
+
+  * Added runtime selection of the optimal architecture-specific CRC path.
+  * Added optimized implementations of CRC32-Ethernet and CRC16-CCITT
+    using the AVX512 and VPCLMULQDQ instruction sets.
+
+* **Added the FEC API, for a generic FEC query and config.**
+
+  Added the FEC API which provides functions for query FEC capabilities and
+  current FEC mode from device. Also, API for configuring FEC mode is also provided.
+
+* **Updated Broadcom bnxt driver.**
+
+  Updated the Broadcom bnxt driver with new features and improvements, including:

+
+* **Added hns3 FEC PMD, for supporting query and config FEC mode.**
+
+  Added the FEC PMD which provides functions for query FEC capabilities and
+  current FEC mode from device. Also, PMD for configuring FEC mode is also provided.
+
+* **Updated Solarflare network PMD.**
+
+  Updated the Solarflare ``sfc_efx`` driver with changes including:
+
+  * Added SR-IOV PF support
+
+* **Updated Virtio driver.**
+
+  * Added support for Vhost-vDPA backend to Virtio-user PMD.
+  * Changed default link speed to unknown.
+  * Added support for 200G link speed.
+
+* **Updated Intel i40e driver.**
+
+  Updated the Intel i40e driver to use write combining stores.
+
+* **Updated Intel ixgbe driver.**
+
+  Updated the Intel ixgbe driver to use write combining stores.
+
+* **Updated Intel ice driver.**
+
+  Updated the Intel ice driver to use write combining stores.
+
+* **Updated Intel qat driver.**
+
+  Updated the Intel qat driver to use write combining stores.
+
+* **Added Ice Lake (Gen4) support for Intel NTB.**
+
+  Added NTB device support (4th generation) for Intel Ice Lake platform.
+
+* **Added UDP/IPv4 GRO support for VxLAN and non-VxLAN packets.**
+
+  For VxLAN packets, added inner UDP/IPv4 support.
+  For non-VxLAN packets, added UDP/IPv4 support.

+  * Added header modify actions.
+  * Added flag action.
+  * Added raw encap/decap actions.
+  * Added VXLAN encap/decap actions.
+  * Added ICMP and ICMP6 matching items.
+  * Added option to set port mask for insertion/deletion:
+    ``--portmask=N``
+    where N represents the hexadecimal bitmask of ports used.
+
+* **Added Marvell OCTEON TX2 regex PMD.**
+
+  Added a new PMD driver for hardware regex offload block for OCTEON TX2 SoC.
+
+  See the :doc:`../regexdevs/octeontx2` for more details.
+
+* **Updated ioat rawdev driver**
+
+  The ioat rawdev driver has been updated and enhanced. Changes include:
+
+  * Added support for Intel\ |reg| Data Streaming Accelerator hardware.
+    For more information, see https://01.org/blogs/2019/introducing-intel-data-streaming-accelerator
+  * Added support for the fill operation via the API ``rte_ioat_enqueue_fill()``,
+    where the hardware fills an area of memory with a repeating pattern.
+  * Added a per-device configuration flag to disable management
+    of user-provided completion handles.
+  * Renamed the ``rte_ioat_do_copies()`` API to ``rte_ioat_perform_ops()``,
+    and renamed the ``rte_ioat_completed_copies()`` API to ``rte_ioat_completed_ops()``
+    to better reflect the APIs' purposes, and remove the implication that
+    they are limited to copy operations only.
+    [Note: The old API is still provided but marked as deprecated in the code]
+  * Added a new API ``rte_ioat_fence()`` to add a fence between operations.
+    This API replaces the ``fence`` flag parameter in the ``rte_ioat_enqueue_copies()`` function,
+    and is clearer as there is no ambiguity as to whether the flag should be
+    set on the last operation before the fence or the first operation after it.
+
+* **Updated the pipeline library for alignment with the P4 language.**
+
+  Added new Software Switch (SWX) pipeline type that provides more
+  flexibility through API and feature alignment with the P4 language.
+
+  * The packet headers, meta-data, actions, tables and pipelines are
+    dynamically defined instead of selected from pre-defined set.
+  * The actions and the pipeline are defined with instructions.
+  * Extern objects and functions can be plugged into the pipeline.
+  * Transaction-oriented table updates.
+
+* **Add new AVX512 specific classify algorithms for ACL library.**
+
+  * Added new ``RTE_ACL_CLASSIFY_AVX512X16`` vector implementation,
+    which can process up to 16 flows in parallel. Requires AVX512 support.
