+ See the :doc:`../vdpadevs/mlx5` guide for more details on this driver.
+
+* **Added support for virtio-PMD notification data.**
+
+ Added support for virtio-PMD notification data so that the driver
+ passes extra data (besides identifying the virtqueue) in its device
+ notifications, expanding the notifications to include the avail index and
+ avail wrap counter (When split ring is used, the avail wrap counter is not
+ included in the notification data).
+
+* **Updated testpmd application.**
+
+ Added support for ESP and L2TPv3 over IP rte_flow patterns to the testpmd
+ application.
+
+* **Added algorithms to cryptodev API.**
+
+ Added new algorithms to the cryptodev API:
+
+ * ECDSA (Elliptic Curve Digital Signature Algorithm) is added to
+ asymmetric crypto library specifications.
+ * ECPM (Elliptic Curve Point Multiplication) is added to
+ asymmetric crypto library specifications.
+
+* **Added synchronous Crypto burst API.**
+
+ A new API has been introduced in the crypto library to handle synchronous cryptographic
+ operations allowing it to achieve performance gains for cryptodevs which use
+ CPU based acceleration, such as Intel AES-NI. An implementation for aesni_gcm
+ cryptodev is provided. The IPsec example application and ipsec library itself
+ were changed to allow utilization of this new feature.
+
+* **Added handling of mixed algorithms in encrypted digest requests in QAT PMD.**
+
+ Added handling of mixed algorithms in encrypted digest hash-cipher
+ (generation) and cipher-hash (verification) requests (e.g. SNOW3G + ZUC or
+ ZUC + AES CTR) in QAT PMD possible when running on GEN3 QAT hardware.
+ Such algorithm combinations are not supported on GEN1/GEN2 hardware
+ and executing the request returns ``RTE_CRYPTO_OP_STATUS_INVALID_SESSION``.
+
+* **Queue-pairs are now thread-safe on Intel QuickAssist Technology (QAT) PMD.**
+
+ Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within
+ a single queue-pair all enqueues to the TX queue must be done from one thread
+ and all dequeues from the RX queue must be done from one thread, but enqueues
+ and dequeues may be done in different threads.).
+
+* **Updated the ZUC PMD.**
+
+ * Transitioned underlying library from libSSO ZUC to intel-ipsec-mb
+ library (minimum version required 0.53).
+ * Removed dynamic library limitation, so PMD can be built as a shared
+ object now.
+
+* **Updated the KASUMI PMD.**
+
+ * Transitioned underlying library from libSSO KASUMI to intel-ipsec-mb
+ library (minimum version required 0.53).
+
+* **Updated the SNOW3G PMD.**
+
+ * Transitioned underlying library from libSSO SNOW3G to intel-ipsec-mb
+ library (minimum version required 0.53).
+
+* **Changed armv8 crypto PMD external dependency.**
+
+ Changed armv8 crypto PMD external dependency. The
+ armv8 crypto PMD now depends on the Arm crypto library, and Marvell's
+ armv8 crypto library is not used anymore. The library name has been changed
+ from armv8_crypto to AArch64crypto.
+
+* **Added inline IPsec support to Marvell OCTEON TX2 PMD.**
+
+ Added inline IPsec support to Marvell OCTEON TX2 PMD. With this feature,
+ applications will be able to offload entire IPsec offload to the hardware.
+ For the configured sessions, hardware will do the lookup and perform
+ decryption and IPsec transformation. For the outbound path, applications
+ can submit a plain packet to the PMD, and it will be sent out on the wire
+ after doing encryption and IPsec transformation of the packet.
+
+* **Added Marvell OCTEON TX2 End Point rawdev PMD.**
+
+ Added a new OCTEON TX2 rawdev PMD for End Point mode of operation.
+ See the :doc:`../rawdevs/octeontx2_ep` for more details on this new PMD.
+
+* **Added event mode to l3fwd sample application.**
+
+ Added event device support for the ``l3fwd`` sample application. It demonstrates
+ usage of poll and event mode IO mechanism under a single application.
+
+* **Added cycle-count mode to the compression performance tool.**
+
+ Enhanced the compression performance tool by adding a cycle-count mode
+ which can be used to help measure and tune hardware and software PMDs.
+
+* **Added OpenWrt howto guide.**
+
+ Added document which describes how to enable DPDK on OpenWrt in both virtual and
+ physical machines.
