   The following changes are planned:
 
-  - removal of ``get_capabilities`` mempool ops and related flags.
   - substitute ``register_memory_area`` with ``populate`` ops.
   - addition of new op to allocate contiguous
     block of objects if underlying driver supports it.

+* **Removed mempool capability flags and related functions.**
+
+  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.

   to allow to customize required memory size calculation.
   A new callback ``populate`` has been added to ``rte_mempool_ops``
   to allow to customize objects population.
+  Callback ``get_capabilities`` has been removed from ``rte_mempool_ops``
+  since its features are covered by ``calc_mem_size`` and ``populate``
+  callbacks.
