47       - ethdev (lib, PMDs)
48       - cryptodev (lib, PMDs)
49       - eventdev (lib, PMDs)

61  has been added, so that the accelerator devices could be seen in DPDK and could
62  be further registered such as a compress, crypto, DMA and ethernet devices.
63
64* **Introduced argument parsing library.**
65
66  The argparse library was added to ease writing user-friendly applications,
67  replacing ``getopt()`` usage.

105  If use with an expression is desired applications can adapt by supplying
106  ``typeof(e)`` as an argument.
107
108* eal: Improved ``RTE_BUILD_BUG_ON`` by using C11 ``static_assert``.
109  Non-constant expressions are now rejected instead of being silently ignored.
