   The ioat rawdev driver has been updated and enhanced. Changes include:
 
+  * Added support for Intel\ |reg| Data Streaming Accelerator hardware.
+    For more information, see https://01.org/blogs/2019/introducing-intel-data-streaming-accelerator
+  * Added support for the fill operation via the API ``rte_ioat_enqueue_fill()``,
+    where the hardware fills an area of memory with a repeating pattern.
   * Added a per-device configuration flag to disable management
     of user-provided completion handles.
+  * Renamed the ``rte_ioat_do_copies()`` API to ``rte_ioat_perform_ops()``,
+    and renamed the ``rte_ioat_completed_copies()`` API to ``rte_ioat_completed_ops()``
+    to better reflect the APIs' purposes, and remove the implication that
+    they are limited to copy operations only.
+    [Note: The old API is still provided but marked as deprecated in the code]
+  * Added a new API ``rte_ioat_fence()`` to add a fence between operations.
+    This API replaces the ``fence`` flag parameter in the ``rte_ioat_enqueue_copies()`` function,
+    and is clearer as there is no ambiguity as to whether the flag should be
+    set on the last operation before the fence or the first operation after it.
 
 * **Updated the pipeline library for alignment with the P4 language.**
