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.
67 * Added raw encap/decap actions.
68 * Added VXLAN encap/decap actions.
69 * Added option to set port mask for insertion/deletion:
71 where N represents the hexadecimal bitmask of ports used.
77 .. This section should contain removed items in this release. Sample format:

84 =======================================================
90 .. This section should contain API changes. Sample format:
92 * sample: Add a short 1-2 sentence description of the API change
93 which was announced in the previous releases and made in this release.
94 Start with a scope label like "ethdev:".
95 Use fixed width quotes for ``function_names`` or ``struct_names``.

100 =======================================================
102 * eal: The ``rte_logs`` struct and global symbol was made private
103 and is no longer part of the API.
105 * eal: Made the ``rte_dev_event`` structure private to the EAL as no public API
108 * mem: Removed the unioned field ``phys_addr`` from
109 the structures ``rte_memseg`` and ``rte_memzone``.
110 The field ``iova`` is remaining from the old unions.
112 * mempool: Removed the unioned fields ``phys_addr`` and ``physaddr`` from
113 the structures ``rte_mempool_memhdr`` and ``rte_mempool_objhdr``.
114 The field ``iova`` is remaining from the old unions.
115 The flag name ``MEMPOOL_F_NO_PHYS_CONTIG`` is removed,
116 while the aliased flag ``MEMPOOL_F_NO_IOVA_CONTIG`` is kept.
118 * mbuf: Removed the functions ``rte_mbuf_data_dma_addr*``
119 and the macros ``rte_pktmbuf_mtophys*``.
120 The same functionality is still available with the functions and macros
121 having ``iova`` in their names instead of ``dma_addr`` or ``mtophys``.
123 * mbuf: Removed the unioned field ``buf_physaddr`` from ``rte_mbuf``.
124 The field ``buf_iova`` is remaining from the old union.
126 * mbuf: Removed the unioned field ``refcnt_atomic`` from
127 the structures ``rte_mbuf`` and ``rte_mbuf_ext_shared_info``.
128 The field ``refcnt`` is remaining from the old unions.
130 * pci: Removed the ``rte_kernel_driver`` enum defined in rte_dev.h and
131 replaced with a private enum in the PCI subsystem.
133 * pci: Removed the PCI resources map API from the public API
134 (``pci_map_resource`` and ``pci_unmap_resource``) and moved it to the
135 PCI bus driver along with the PCI resources lists and associated structures
136 (``pci_map``, ``pci_msix_table``, ``mapped_pci_resource`` and
137 ``mapped_pci_res_list``).
139 * ethdev: Removed the ``kdrv`` field in the ethdev ``rte_eth_dev_data``
140 structure as it gave no useful abstracted information to the applications.
142 * ethdev: ``rte_eth_rx_descriptor_done()`` API has been deprecated.
144 * Renamed internal ethdev APIs:
146 * ``_rte_eth_dev_callback_process()`` -> ``rte_eth_dev_callback_process()``
147 * ``_rte_eth_dev_reset`` -> ``rte_eth_dev_internal_reset()``
149 * rawdev: Added a structure size parameter to the functions
150 ``rte_rawdev_queue_setup()``, ``rte_rawdev_queue_conf_get()``,
151 ``rte_rawdev_info_get()`` and ``rte_rawdev_configure()``,
152 allowing limited driver type-checking and ABI compatibility.
154 * rawdev: Changed the return type of the function ``rte_dev_info_get()``
155 and the function ``rte_rawdev_queue_conf_get()``
156 from ``void`` to ``int`` allowing the return of error codes from drivers.
158 * bpf: ``RTE_BPF_XTYPE_NUM`` has been dropped from ``rte_bpf_xtype``.
164 .. This section should contain ABI changes. Sample format:
166 * sample: Add a short 1-2 sentence description of the ABI change
167 which was announced in the previous releases and made in this release.
168 Start with a scope label like "ethdev:".
169 Use fixed width quotes for ``function_names`` or ``struct_names``.

173 Also, make sure to start the actual text at the margin.
174 =======================================================
178 * Following device operation function pointers moved
179 from ``struct eth_dev_ops`` to ``struct rte_eth_dev``:
181 * ``eth_rx_queue_count_t rx_queue_count;``
182 * ``eth_rx_descriptor_done_t rx_descriptor_done;``
183 * ``eth_rx_descriptor_status_t rx_descriptor_status;``
184 * ``eth_tx_descriptor_status_t tx_descriptor_status;``
186 * ``struct eth_dev_ops`` is no more accessible by applications,
187 which was already internal data structure.
189 * ``ethdev`` internal functions are marked with ``__rte_internal`` tag.
195 .. This section should contain new known issues in this release. Sample format:
197 * **Add title in present tense with full stop.**
199 Add a short 1-2 sentence description of the known issue
200 in the present tense. Add information on any known workarounds.
202 This section is a comment. Do not overwrite or remove it.
203 Also, make sure to start the actual text at the margin.
204 =======================================================
210 .. This section should contain a list of platforms that were tested
215 * <vendor> platform with <vendor> <type of devices> combinations
220 * Other relevant details...
