 Deprecation Notices
 -------------------
 
+* linux: Linux kernel version 3.2 (which is the current minimum required
+  version for the DPDK) is not maintained anymore. Therefore the planned
+  minimum required kernel version for DPDK 19.02 will be the next oldest
+  Long Term Stable (LTS) version which is 3.16, but compatibility for
+  recent distribution kernels will be kept.
+
+* 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: both declaring and identifying devices will be streamlined in v18.11.
   New functions will appear to query a specific port from buses, classes of
   device and device drivers. Device declaration will be made coherent with the

-* 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.
+* dpaa2: removal of ``rte_dpaa2_memsegs`` structure which has been replaced
+  by a pa-va search library. This structure was earlier being used for holding
+  memory segments used by dpaa2 driver for faster pa->va translation. This
+  structure would be made internal (or removed if all dependencies are cleared)
+  in future releases.
 
 * mbuf: the macro ``RTE_MBUF_INDIRECT()`` will be removed in v18.08 or later and

   Target release for removal of the legacy API will be defined once most
   PMDs have switched to rte_flow.
 
-* pdump: As we changed to use generic IPC, some changes in APIs and structure
-  are expected in subsequent release.
+* ethdev: Maximum and minimum MTU values vary between hardware devices. In
+  hardware agnostic DPDK applications access to such information would allow
+  a more accurate way of validating and setting supported MTU values on a per
+  device basis rather than using a defined default for all devices. To
+  resolve this, the following members will be added to ``rte_eth_dev_info``.
+  Note: these can be added to fit a hole in the existing structure for amd64
+  but not for 32-bit, as such ABI change will occur as size of the structure
+  will increase.
+
+  - Member ``uint16_t min_mtu`` the minimum MTU allowed.
+  - Member ``uint16_t max_mtu`` the maximum MTU allowed.
+
+* security: New field ``uint64_t opaque_data`` is planned to be added into
+  ``rte_security_session`` structure. That would allow upper layer to easily
+  associate/de-associate some user defined data with the security session.
+
+* cryptodev: several API and ABI changes are planned for rte_cryptodev
+  in v19.02:
+
+  - The size and layout of ``rte_cryptodev_sym_session`` will change
+    to fix existing issues.
+  - The size and layout of ``rte_cryptodev_qp_conf`` and syntax of
+    ``rte_cryptodev_queue_pair_setup`` will change to to allow to use
+    two different mempools for crypto and device private sessions.
 
-  - ``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.
+* crypto/aesni_mb: the minimum supported intel-ipsec-mb library version will be
