+* mbuf: The control mbuf API has been removed in v18.05. The impacted
+ functions and macros are:
+
+ - ``rte_ctrlmbuf_init()``
+ - ``rte_ctrlmbuf_alloc()``
+ - ``rte_ctrlmbuf_free()``
+ - ``rte_ctrlmbuf_data()``
+ - ``rte_ctrlmbuf_len()``
+ - ``rte_is_ctrlmbuf()``
+ - ``CTRL_MBUF_FLAG``
+
+ The packet mbuf API should be used as a replacement.
+
+* meter: updated to accommodate configuration profiles.
+
+ The meter API is changed to support meter configuration profiles. The
+ configuration profile represents the set of configuration parameters
+ for a given meter object, such as the rates and sizes for the token
+ buckets. These configuration parameters were previously the part of meter
+ object internal data strcuture. The separation of the configuration
+ parameters from meter object data structure results in reducing its
+ memory footprint which helps in better cache utilization when large number
+ of meter objects are used.
