+* **Added MCS lock.**
+
+  MCS lock provides scalability by spinning on a CPU/thread local variable
+  which avoids expensive cache bouncings.
+  It provides fairness by maintaining a list of acquirers and passing
+  the lock to each CPU/thread in the order they acquired the lock.

+* **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

+* **Updated TURBO_SW bbdev PMD.**
+
+  Updated the ``turbo_sw`` bbdev driver with changes including:
+
+  * Added option to build the driver with or without dependency of external
+    SDK libraries.
+  * Added support for 5GNR encode/decode operations.
+
+* **Updated the QuickAssist Technology (QAT) symmetric crypto PMD.**
