9 .. **Read this first.**
11 The text in the sections below explains how to update the release notes.
13 Use proper spelling, capitalization and punctuation in all sections.
15 Variable and config names should be quoted as fixed width text:
18 Build the docs and view the output file to ensure the changes are correct::

27 .. This section should contain new features added in this release.
30 * **Add a title in the past tense with a full stop.**
32 Add a short 1-2 sentence description in the past tense.
33 The description should be enough to allow someone scanning
34 the release notes to understand the new feature.
36 If the feature adds a lot of sub-features you can use a bullet list
39 * Added feature foo to do something.
40 * Enhanced feature bar to do something else.
42 Refer to the previous release notes for examples.
44 Suggested order in release notes items:
45 * Core libs (EAL, mempool, ring, mbuf, buses)
46 * Device abstraction libs and PMDs
48 - cryptodev (lib, PMDs)
49 - eventdev (lib, PMDs)
52 * Apps, Examples, Tools (if significant)

56 =======================================================
58 * **Extended flow-perf application.**
60 * Started supporting user order instead of bit mask:
61 Now the user can create any structure of rte_flow
62 using flow performance application with any order,
63 moreover the app also now starts to support inner
64 items matching as well.
65 * Added header modify actions.
71 .. This section should contain removed items in this release. Sample format:
73 * Add a short 1-2 sentence description of the removed item

77 Also, make sure to start the actual text at the margin.
78 =======================================================
84 .. This section should contain API changes. Sample format:
86 * sample: Add a short 1-2 sentence description of the API change
87 which was announced in the previous releases and made in this release.
88 Start with a scope label like "ethdev:".
89 Use fixed width quotes for ``function_names`` or ``struct_names``.

94 =======================================================
96 * eal: The ``rte_logs`` struct and global symbol was made private
97 and is no longer part of the API.
99 * eal: Made the ``rte_dev_event`` structure private to the EAL as no public API
102 * mem: Removed the unioned field ``phys_addr`` from
103 the structures ``rte_memseg`` and ``rte_memzone``.
104 The field ``iova`` is remaining from the old unions.
106 * mempool: Removed the unioned fields ``phys_addr`` and ``physaddr`` from
107 the structures ``rte_mempool_memhdr`` and ``rte_mempool_objhdr``.
108 The field ``iova`` is remaining from the old unions.
109 The flag name ``MEMPOOL_F_NO_PHYS_CONTIG`` is removed,
110 while the aliased flag ``MEMPOOL_F_NO_IOVA_CONTIG`` is kept.
112 * mbuf: Removed the functions ``rte_mbuf_data_dma_addr*``
113 and the macros ``rte_pktmbuf_mtophys*``.
114 The same functionality is still available with the functions and macros
115 having ``iova`` in their names instead of ``dma_addr`` or ``mtophys``.
117 * mbuf: Removed the unioned field ``buf_physaddr`` from ``rte_mbuf``.
118 The field ``buf_iova`` is remaining from the old union.
120 * mbuf: Removed the unioned field ``refcnt_atomic`` from
121 the structures ``rte_mbuf`` and ``rte_mbuf_ext_shared_info``.
122 The field ``refcnt`` is remaining from the old unions.
124 * pci: Removed the ``rte_kernel_driver`` enum defined in rte_dev.h and
125 replaced with a private enum in the PCI subsystem.
127 * pci: Removed the PCI resources map API from the public API
128 (``pci_map_resource`` and ``pci_unmap_resource``) and moved it to the
129 PCI bus driver along with the PCI resources lists and associated structures
130 (``pci_map``, ``pci_msix_table``, ``mapped_pci_resource`` and
131 ``mapped_pci_res_list``).
133 * ethdev: Removed the ``kdrv`` field in the ethdev ``rte_eth_dev_data``
134 structure as it gave no useful abstracted information to the applications.
136 * ethdev: ``rte_eth_rx_descriptor_done()`` API has been deprecated.
138 * Renamed internal ethdev APIs:
140 * ``_rte_eth_dev_callback_process()`` -> ``rte_eth_dev_callback_process()``
141 * ``_rte_eth_dev_reset`` -> ``rte_eth_dev_internal_reset()``
143 * rawdev: Added a structure size parameter to the functions
144 ``rte_rawdev_queue_setup()``, ``rte_rawdev_queue_conf_get()``,
145 ``rte_rawdev_info_get()`` and ``rte_rawdev_configure()``,
146 allowing limited driver type-checking and ABI compatibility.
148 * rawdev: Changed the return type of the function ``rte_dev_info_get()``
149 and the function ``rte_rawdev_queue_conf_get()``
150 from ``void`` to ``int`` allowing the return of error codes from drivers.
152 * bpf: ``RTE_BPF_XTYPE_NUM`` has been dropped from ``rte_bpf_xtype``.
158 .. This section should contain ABI changes. Sample format:
160 * sample: Add a short 1-2 sentence description of the ABI change
161 which was announced in the previous releases and made in this release.
162 Start with a scope label like "ethdev:".
163 Use fixed width quotes for ``function_names`` or ``struct_names``.

167 Also, make sure to start the actual text at the margin.
168 =======================================================
172 * Following device operation function pointers moved
173 from ``struct eth_dev_ops`` to ``struct rte_eth_dev``:
175 * ``eth_rx_queue_count_t rx_queue_count;``
176 * ``eth_rx_descriptor_done_t rx_descriptor_done;``
177 * ``eth_rx_descriptor_status_t rx_descriptor_status;``
178 * ``eth_tx_descriptor_status_t tx_descriptor_status;``
180 * ``struct eth_dev_ops`` is no more accessible by applications,
181 which was already internal data structure.
183 * ``ethdev`` internal functions are marked with ``__rte_internal`` tag.
189 .. This section should contain new known issues in this release. Sample format:
191 * **Add title in present tense with full stop.**
193 Add a short 1-2 sentence description of the known issue
194 in the present tense. Add information on any known workarounds.
196 This section is a comment. Do not overwrite or remove it.
197 Also, make sure to start the actual text at the margin.
198 =======================================================
204 .. This section should contain a list of platforms that were tested
209 * <vendor> platform with <vendor> <type of devices> combinations
214 * Other relevant details...
216 This section is a comment. Do not overwrite or remove it.
217 Also, make sure to start the actual text at the margin.
