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::

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

57 =========================================================
59 * **New synchronization modes for rte_ring.**
61 Introduced new optional MT synchronization mode for rte_ring:
62 Relaxed Tail Sync (RTS). With this mode selected, rte_ring shows
63 significant improvements for average enqueue/dequeue times on
64 overcommitted systems.
66 * **Updated Mellanox mlx5 driver.**
68 Updated Mellanox mlx5 driver with new features and improvements, including:
70 * Added support for matching on IPv4 Time To Live and IPv6 Hop Limit.
72 * **Added handling of mixed crypto algorithms in QAT PMD for GEN2.**
74 Enabled handling of mixed algorithms in encrypted digest hash-cipher
75 (generation) and cipher-hash (verification) requests in QAT PMD
76 when running on GEN2 QAT hardware with particular firmware versions
77 (GEN3 support was added in DPDK 20.02).
79 * **Updated the turbo_sw bbdev PMD.**
81 Supported large size code blocks which does not fit in one mbuf segment.
83 * **Added event mode to ipsec-secgw application.**
85 Updated ipsec-secgw application to add event based packet processing. The worker
86 thread(s) would receive events and submit them back to the event device after
87 the processing. This way, multicore scaling and HW assisted scheduling is achieved
88 by making use of the event device capabilities. The event mode currently supports
89 only inline IPsec protocol offload.
