+* **Added support for procinfo and pdump on eth vdev.**
+
+  For ethernet virtual devices (like tap, pcap, etc), with this feature, we can get
+  stats/xstats on shared memory from secondary process, and also pdump packets on

+* service cores: no longer marked as experimental.
+
+  The service cores functions are no longer marked as experimental, and have
+  become part of the normal DPDK API and ABI. Any future ABI changes will be
+  announced at least one release before the ABI change is made. There are no
+  ABI breaking changes planned.
+
+* eal: ``rte_lcore_has_role()`` return value changed.
+
+  This function now returns true or false, respectively,
+  rather than 0 or <0 for success or failure.
+  It makes use of the function more intuitive.
+
+* mempool: capability flags and related functions have been removed.
+
+  Flags ``MEMPOOL_F_CAPA_PHYS_CONTIG`` and
+  ``MEMPOOL_F_CAPA_BLK_ALIGNED_OBJECTS`` were used by octeontx mempool
+  driver to customize generic mempool library behaviour.
+  Now the new driver callbacks ``calc_mem_size`` and ``populate`` may be
+  used to achieve it without specific knowledge in the generic code.
+
+* mempool: xmem functions have been deprecated:
+
+  - ``rte_mempool_xmem_create``
+  - ``rte_mempool_xmem_size``
+  - ``rte_mempool_xmem_usage``
+  - ``rte_mempool_populate_iova_tab``
