   renamed the application from SW PMD specific ``eventdev_pipeline_sw_pmd``
   to PMD agnostic ``eventdev_pipeline``.
 
+* **Added Rawdev, a generic device support library.**
+
+  Rawdev library provides support for integrating any generic device type with
+  DPDK framework. Generic devices are those which do not have a pre-defined
+  type within DPDK, for example, ethernet, crypto, event etc.
+  A set of northbound APIs have been defined which encompass a generic set of
+  operations by allowing applications to interact with device using opaque
+  structures/buffers. Also, southbound APIs provide APIs for integrating device
+  either as as part of a physical bus (PCI, FSLMC etc) or through ``vdev``.
+
+  See the :doc:`../prog_guide/rawdev` programmer's guide for more details.
+
+* **Added new multi-process communication channel**
+
+  Added a generic channel in EAL for multi-process (primary/secondary) communication.
+  Consumers of this channel need to register an action with an action name to response
+  a message received; the actions will be identified by the action name and executed
+  in the context of a new dedicated thread for this channel. The list of new APIs:
+
+  * ``rte_mp_register`` and ``rte_mp_unregister`` are for action (un)registration.
+  * ``rte_mp_sendmsg`` is for sending a message without blocking for a response.
+  * ``rte_mp_request`` is for sending a request message and will block until
+    it gets a reply message which is sent from the peer by ``rte_mp_reply``.
+
+* **Added new DPDK build system using the tools "meson" and "ninja" [EXPERIMENTAL]**
+
+  Added in support for building DPDK using ``meson`` and ``ninja``, which gives
+  additional features, such as automatic build-time configuration, over the
+  current build system using ``make``. For instructions on how to do a DPDK build
+  using the new system, see the instructions in ``doc/build-sdk-meson.txt``.
+
+.. note::
+
+    This new build system support is incomplete at this point and is added
+    as experimental in this release. The existing build system using ``make``
+    is unaffected by these changes, and can continue to be used for this
+    and subsequent releases until such time as it's deprecation is announced.
