 Deprecation Notices
 -------------------
 
-* The following fields have been deprecated in rte_eth_stats:
-  ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss,
-  tx_pause_xon, rx_pause_xon, tx_pause_xoff, rx_pause_xoff
+* igb_uio: iomem mapping and sysfs files created for iomem and ioport in
+  igb_uio will be removed, because we are able to detect these from what Linux
+  has exposed, like the way we have done with uio-pci-generic. This change
+  targets release 17.05.
 
-* The scheduler statistics structure will change to allow keeping track of
-  RED actions.
+* ``eth_driver`` is planned to be removed in 17.02. This currently serves as
+  a placeholder for PMDs to register themselves. Changes for ``rte_bus`` will
+  provide a way to handle device initialization currently being done in
+  ``eth_driver``.
 
-* librte_pipeline: The prototype for the pipeline input port, output port
-  and table action handlers will be updated:
-  the pipeline parameter will be added, the packets mask parameter will be
-  either removed (for input port action handler) or made input-only.
+* ethdev: an API change is planned for 17.02 for the function
+  ``_rte_eth_dev_callback_process``. In 17.02 the function will return an ``int``
+  instead of ``void`` and a fourth parameter ``void *ret_param`` will be added.
+
+* ABI changes are planned for 17.05 in the ``rte_mbuf`` structure: some fields
+  may be reordered to facilitate the writing of ``data_off``, ``refcnt``, and
+  ``nb_segs`` in one operation, because some platforms have an overhead if the
+  store address is not naturally aligned. Other mbuf fields, such as the
+  ``port`` field, may be moved or removed as part of this mbuf work. A
+  ``timestamp`` will also be added.
+
+* The mbuf flags PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT are deprecated and
+  are respectively replaced by PKT_RX_VLAN_STRIPPED and
+  PKT_RX_QINQ_STRIPPED, that are better described. The old flags and
+  their behavior will be kept until 17.02 and will be removed in 17.05.
+
+* mempool: The functions ``rte_mempool_count`` and ``rte_mempool_free_count``
+  will be removed in 17.05.
+  They are replaced by ``rte_mempool_avail_count`` and
+  ``rte_mempool_in_use_count`` respectively.
+
+* mempool: The functions for single/multi producer/consumer are deprecated
+  and will be removed in 17.05.
+  It is replaced by ``rte_mempool_generic_get/put`` functions.
+
+* ethdev: the legacy filter API, including
+  ``rte_eth_dev_filter_supported()``, ``rte_eth_dev_filter_ctrl()`` as well
+  as filter types MACVLAN, ETHERTYPE, FLEXIBLE, SYN, NTUPLE, TUNNEL, FDIR,
+  HASH and L2_TUNNEL, is superseded by the generic flow API (rte_flow) in
+  PMDs that implement the latter.
+  Target release for removal of the legacy API will be defined once most
+  PMDs have switched to rte_flow.
+
+* distributor: library API will be changed to incorporate a burst-oriented
+  API. This will include a change to ``rte_distributor_create``
+  to specify which type of instance to create (single or burst), and
+  additional calls for ``rte_distributor_poll_pkt_burst`` and
+  ``rte_distributor_return_pkt_burst``, among others.
