     high performance
   * Added multi-queue support to allow one af_xdp vdev with multiple netdev
     queues
+  * Enabled need_wakeup feature which can provide efficient support for case
+    that application and driver executing on the same core.
+
+* **Enabled infinite Rx in the PCAP PMD.**
+
+  Added an infinite Rx feature which allows packets in the Rx PCAP of a PCAP
+  device to be received repeatedly at a high rate. This can be useful for quick
+  performance testing of DPDK apps.
+
+* **Added a FPGA_LTE_FEC bbdev PMD.**
+
+  Added the new ``fpga_lte_fec`` bbdev driver for the Intel® FPGA PAC
+  (Programmable  Acceleration Card) N3000.  See the
+  :doc:`../bbdevs/fpga_lte_fec` BBDEV guide for more details on this new driver.
+
+* **Added Intel QuickData Technology PMD**
+
+  The PMD for Intel\ |reg|  QuickData Technology, part of
+  Intel\ |reg|  I/O Acceleration Technology `(Intel I/OAT)
+  <https://www.intel.com/content/www/us/en/wireless-network/accel-technology.html>`_,
+  allows data copies to be done by hardware instead
+  of via software, reducing cycles spent copying large blocks of data in
+  applications.
+
+* **Introduced NTB PMD.**
+
+  Added a PMD for Intel NTB (Non-transparent Bridge). This PMD implemented
+  handshake between two separate hosts and can share local memory for peer
+  host to directly access.
 
 * **Updated telemetry library for global metrics support.**

    =========================================================
 
+* The ``rte_mem_config`` structure has been made private. The new accessor
+  ``rte_mcfg_*`` functions were introduced to provide replacement for direct
+  access to the shared mem config.
+
 * The network structures, definitions and functions have
   been prefixed by ``rte_`` to resolve conflicts with libc headers.
 
+* malloc: The function ``rte_malloc_set_limit`` was never implemented
+  is deprecated and will be removed in a future release.
+
+* eventdev: No longer marked as experimental.
+
+  The eventdev functions are no longer marked as experimental, and have
+  become part of the normal DPDK API and ABI. Any future ABI changes will be
+  announced at least one release before the ABI change is made. There are no
+  ABI breaking changes planned.

    =========================================================
 
+* eventdev: Event based Rx adapter callback
+
+  The mbuf pointer array in the event eth Rx adapter callback
+  has been replaced with an event array. Using
+  an event array allows the application to change attributes
+  of the events enqueued by the SW adapter.
+
+  The callback can drop packets and populate
+  a callback argument with the number of dropped packets.
+  Add a Rx adapter stats field to keep track of the total
+  number of dropped packets.
+
+* cryptodev: New member in ``rte_cryptodev_config`` to allow applications to
+  disable features supported by the crypto device. Only the following features
+  would be allowed to be disabled this way,
+
+  - ``RTE_CRYPTODEV_FF_SYMMETRIC_CRYPTO``
+  - ``RTE_CRYPTODEV_FF_ASYMMETRIC_CRYPTO``
+  - ``RTE_CRYPTODEV_FF_SECURITY``
+
+  Disabling unused features would facilitate efficient usage of HW/SW offload.
