Removed Items
-------------
Also, make sure to start the actual text at the margin.
=======================================================
+* Removed support for Intel DLB V1 hardware. This is not a broad market device,
+ and existing customers already obtain the source code directly from Intel.
+
API Changes
-----------
Also, make sure to start the actual text at the margin.
=======================================================
+* eal: The experimental TLS API added in ``rte_thread.h`` has been renamed
+ from ``rte_thread_tls_*`` to ``rte_thread_*`` to avoid naming redundancy
+ and confusion with the transport layer security term.
+
+* pci: The value ``PCI_ANY_ID`` is marked as deprecated
+ and can be replaced with ``RTE_PCI_ANY_ID``.
+
+* ethdev: Added a ``rte_flow`` pointer parameter to the function
+ ``rte_flow_dev_dump()`` allowing dump for single flow.
+
+* cryptodev: The experimental raw data path API for dequeue
+ ``rte_cryptodev_raw_dequeue_burst`` got a new parameter
+ ``max_nb_to_dequeue`` to provide flexible control on dequeue.
+
+* 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.
+
ABI Changes
-----------
* No ABI change that would break compatibility with 20.11.
+* The experimental function ``rte_telemetry_legacy_register`` has been
+ removed from the public API and is now an internal-only function. This
+ function was already marked as internal in the API documentation for it,
+ and was not for use by external applications.
+
