The lock-free stack implementation is enabled for aarch64 platforms.
+* **Changed mempool allocation behaviour.**
+
+ Objects are no longer across pages by default.
+ It may consume more memory when using small memory pages.
+
* **Added support of dynamic fields and flags in mbuf.**
This new feature adds the ability to dynamically register some room
Added eBPF JIT support for arm64 architecture to improve the eBPF program
performance.
+* **Added RIB and FIB (Routing/Forwarding Information Base) libraries.**
+
+ RIB and FIB can replace the LPM (Longest Prefix Match) library
+ with better control plane (RIB) performance.
+ The data plane (FIB) can be extended with new algorithms.
+
* **Updated testpmd.**
* Added a console command to testpmd app, ``show port (port_id) ptypes`` which
gives ability to print port supported ptypes in different protocol layers.
+* **Added new example l2fwd-event application.**
+
+ Added an example application `l2fwd-event` that adds event device support to
+ traditional l2fwd example. It demonstrates usage of poll and event mode IO
+ mechanism under a single application.
+
+* **Added build support for Link Time Optimization.**
+
+ LTO is an optimization technique used by the compiler to perform whole
+ program analysis and optimization at link time. In order to do that
+ compilers store their internal representation of the source code that
+ the linker uses at the final stage of compilation process.
+
+ See :doc:`../prog_guide/lto` for more information:

Removed Items
-------------
* Quota and Watermark
* vhost-scsi
+* Removed arm64-dpaa2-* build config. arm64-dpaa-* can now build for both
+ dpaa and dpaa2 platforms.
+
API Changes
-----------
* mem: hid the internal ``malloc_heap`` structure and the
``rte_malloc_heap.h`` header.
+* vfio: removed ``rte_vfio_dma_map`` and ``rte_vfio_dma_unmap`` that have
+ been marked as deprecated in release 19.05.
+ ``rte_vfio_container_dma_map`` and ``rte_vfio_container_dma_unmap`` can
+ be used as substitutes.
+
* pci: removed the following functions deprecated since dpdk v17.11:
- ``eal_parse_pci_BDF`` replaced by ``rte_pci_addr_parse``
