      =========================================================
 
+* **Added Trace Library and Tracepoints**
+
+  A native implementation of ``common trace format(CTF)`` based trace library
+  has been added to provide the ability to add tracepoints in
+  application/library to get runtime trace/debug information for control and
+  fast APIs with minimum impact on fast path performance.
+  Typical trace overhead is ~20 cycles and instrumentation overhead is 1 cycle.
+  Added tracepoints in ``EAL``, ``ethdev``, ``cryptodev``, ``eventdev`` and
+  ``mempool`` libraries for important functions.
+
 * **Added new API for rte_ring.**
 
   * New synchronization modes for rte_ring.
