+* ethdev: The experimental flow API for shared action has been generalized
+ as a flow action handle used in rules through an indirect action.
+ The functions ``rte_flow_shared_action_*`` manipulating the action object
+ are replaced with ``rte_flow_action_handle_*``.
+ The action ``RTE_FLOW_ACTION_TYPE_SHARED`` is deprecated and can be
+ replaced with ``RTE_FLOW_ACTION_TYPE_INDIRECT``.
+
+* ethdev: The experimental function ``rte_mtr_policer_actions_update()``,
+ the enum ``rte_mtr_policer_action``, and the struct members
+ ``policer_action_recolor_supported`` and ``policer_action_drop_supported``
+ have been removed.
+
+* vhost: The vhost library currently populates received mbufs from a virtio
+ driver with Tx offload flags while not filling Rx offload flags.
+ While this behavior is arguable, it is kept untouched.
+ A new flag ``RTE_VHOST_USER_NET_COMPLIANT_OL_FLAGS`` has been added to ask
+ for a behavior compliant with the mbuf offload API.
+
+* 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.
