+* **Added TAP Rx/Tx queues sharing with a secondary process.**
+
+  A secondary process can attach a TAP device created in the primary process,
+  probe the queues, and process Rx/Tx in a secondary process.
+
+* **Added classification and metering support to SoftNIC PMD.**
+
+  Added support for flow classification (rte_flow API), and metering and
+  policing (rte_mtr API) to the SoftNIC PMD.
+
+* **Added Crypto support to Softnic PMD.**
+
+  The Softnic is now capable of processing symmetric crypto workloads such
+  as cipher, cipher-authentication chaining, and aead encryption and
+  decryption. This is achieved by calling DPDK Cryptodev APIs.
+
+* **Added cryptodev port to port library.**
+
+  Cryptodev port is a shim layer in the port library that interacts with DPDK
+  Cryptodev PMDs including burst enqueuing and dequeuing crypto operations.
+
+* **Added symmetric cryptographic actions to the pipeline library.**
+
+  In the pipeline library an added symmetric crypto action parsing and action
+  handler are implemented. The action allows automatically preparing the crypto
+  operation with the rules specified such as algorithm, key, and IV, etc for
+  the cryptodev port to process.

   Added support for the third generation of Intel QuickAssist devices.

+* **Added extendable bucket feature to hash library (rte_hash).**
+
+  This new “extendable bucket” feature provides 100% insertion guarantee to
+  the capacity specified by the user by extending hash table with extra
+  buckets when needed to accommodate the unlikely event of intensive hash
+  collisions.  In addition, the internal hashing algorithm was changed to use
+  partial-key hashing to improve memory efficiency and lookup performance.
+
+* **Added lock free reader/writer concurrency to hash library (rte_hash).**
+
+  Lock free reader/writer concurrency prevents the readers from getting
+  blocked due to a pre-empted writer thread. This allows the hash library
+  to be used in scenarios where the writer thread runs on control plane.
+
+* **Added Traffic Pattern Aware Power Control Library**
+
+  Added an experimental library. This extend Power Library and provide
+  empty_poll APIs. This feature measure how many times empty_poll are
+  executed per core, use the number of empty polls as a hint for system
+  power management.
+
+  See the :doc:`../prog_guide/power_man` section of the DPDK Programmers
+  Guide document for more information.
+
+* **Added JSON power policy interface for containers.**
+
+  Extended the Power Library and vm_power_manager sample app to allow power
+  policies to be submitted via a FIFO using JSON formatted strings. Previously
+  limited to Virtual Machines, this feature extends power policy functionality
+  to containers and host applications that need to have their cores frequency
+  controlled based on the rules contained in the policy.
