+* stack: Lock-free ``rte_stack`` no longer silently ignores push and pop when
+ it's not supported on the current platform. Instead ``rte_stack_create()``
+ fails and ``rte_errno`` is set to ``ENOTSUP``.
+
+* raw/ioat: The experimental function ``rte_ioat_completed_ops()`` now
+ supports two additional parameters, ``status`` and ``num_unsuccessful``,
+ to allow the reporting of errors from hardware when performing copy
+ operations.
