+* **Updated the QAT PMD.**
+
+ The QAT PMD was updated with additional support for:
+
+ * DES algorithm.
+ * Scatter-gather list (SGL) support.
+
+* **Updated the AESNI MB PMD.**
+
+ * The Intel(R) Multi Buffer Crypto for IPsec library used in
+ AESNI MB PMD has been moved to a new repository, in GitHub.
+ * Support for single operations (cipher only and authentication only).
+
+* **Updated the AES-NI GCM PMD.**
+
+ The AES-NI GCM PMD was migrated from MB library to ISA-L library.
+ The migration entailed the following additional support for:
+
+ * GMAC algorithm.
+ * 256-bit cipher key.
+ * Session-less mode.
+ * Out-of place processing
+ * Scatter-gatter support for chained mbufs (only out-of place and destination
+ mbuf must be contiguous)
+
+* **Added Elastic Flow Distributor library (rte_efd).**
+
+ This new library uses perfect hashing to determine a target/value for a
+ given incoming flow key.
+
+ It does not store the key itself for lookup operations, and therefore,
+ lookup performance is not dependent on the key size. Also, the target/value
+ can be any arbitrary value (8 bits by default). Finally, the storage requirement
+ is much smaller than a hash-based flow table and therefore, it can better fit for
+ CPU cache, being able to scale to millions of flow keys.
+
+ See the :ref:`Elastic Flow Distributor Library <Efd_Library>` documentation in
+ the Programmers Guide document, for more information.
