230 =======================================================
232 * eal: The experimental TLS API added in ``rte_thread.h`` has been renamed
233 from ``rte_thread_tls_*`` to ``rte_thread_*`` to avoid naming redundancy
234 and confusion with the transport layer security term.
236 * pci: The value ``PCI_ANY_ID`` is marked as deprecated
237 and can be replaced with ``RTE_PCI_ANY_ID``.
239 * cryptodev: The experimental raw data path API for dequeue
240 ``rte_cryptodev_raw_dequeue_burst`` got a new parameter
241 ``max_nb_to_dequeue`` to provide flexible control on dequeue.
247 .. This section should contain ABI changes. Sample format:

256 Also, make sure to start the actual text at the margin.
257 =======================================================
259 * No ABI change that would break compatibility with 20.11.
261 * The experimental function ``rte_telemetry_legacy_register`` has been
262 removed from the public API and is now an internal-only function. This
263 function was already marked as internal in the API documentation for it,
264 and was not for use by external applications.

272 * **Add title in present tense with full stop.**
274 Add a short 1-2 sentence description of the known issue
275 in the present tense. Add information on any known workarounds.
