+* meson: The minimum supported version of meson for configuring and building
+  DPDK will be increased to v0.47.1 (from 0.41) from DPDK 19.05 onwards. For
+  those users with a version earlier than 0.47.1, an updated copy of meson
+  can be got using the ``pip``, or ``pip3``, tool for downloading python
+  packages.

 * kvargs: The function ``rte_kvargs_process`` will get a new parameter
   for returning key match count. It will ease handling of no-match case.

-* eal: function ``rte_bsf64`` in ``rte_bitmap.h`` has been renamed to
-  ``rte_bsf64_safe`` and moved to ``rte_common.h``. A new ``rte_bsf64`` function

-  set by existing ``rte_bsf32`` function.

-* mbuf: The opaque ``mbuf->hash.sched`` field will be updated to support generic
-  definition in line with the ethdev TM and MTR APIs. Currently, this field
-  is defined in librte_sched in a non-generic way. The new generic format
-  will contain: queue ID, traffic class, color. Field size will not change.
-
-* mbuf: the macro ``RTE_MBUF_INDIRECT()`` will be removed in v18.08 or later and
-  replaced with ``RTE_MBUF_CLONED()`` which is already added in v18.05. As
-  ``EXT_ATTACHED_MBUF`` is newly introduced in v18.05, ``RTE_MBUF_INDIRECT()``
-  can no longer be mutually exclusive with ``RTE_MBUF_DIRECT()`` if the new
-  experimental API ``rte_pktmbuf_attach_extbuf()`` is used. Removal of the macro
-  is to fix this semantic inconsistency.

-* pdump: As we changed to use generic IPC, some changes in APIs and structure
-  are expected in subsequent release.
+* kni: remove KNI ethtool support. To clarify, this is not to remove the KNI,
+  but only to remove ethtool support of it that is disabled by default and
+  can be enabled via ``CONFIG_RTE_KNI_KMOD_ETHTOOL`` config option.
+  Existing KNI ethtool implementation is only supported by ``igb`` & ``ixgbe``
+  drivers, by using a copy of kernel drivers in DPDK. This model cannot be
+  extended to all drivers in DPDK and it is too much effort to maintain
+  kernel modules in DPDK. As a result users won't be able to use ``ethtool``
+  via ``igb`` & ``ixgbe`` anymore.
+
+* cryptodev: New member in ``rte_cryptodev_config`` to allow applications to
+  disable features supported by the crypto device. Only the following features
+  would be allowed to be disabled this way,
+
+  - ``RTE_CRYPTODEV_FF_SYMMETRIC_CRYPTO``
+  - ``RTE_CRYPTODEV_FF_ASYMMETRIC_CRYPTO``
+  - ``RTE_CRYPTODEV_FF_SECURITY``
+
+  Disabling unused features would facilitate efficient usage of HW/SW offload.
+
+  - Member ``uint64_t ff_disable`` in ``rte_cryptodev_config``
+
+  The field would be added in v19.08.

 
 

-  - ``rte_pdump_set_socket_dir`` will be removed;
-  - The parameter, ``path``, of ``rte_pdump_init`` will be removed;
-  - The enum ``rte_pdump_socktype`` will be removed.
+* cryptodev: the ``uint8_t *data`` member of ``key`` structure in the xforms
+  structure (``rte_crypto_cipher_xform``, ``rte_crypto_auth_xform``, and
+  ``rte_crypto_aead_xform``) will be changed to ``const uint8_t *data``.
