 * metrics: The function ``rte_metrics_init`` will have a non-void return
   in order to notify errors instead of calling ``rte_exit``.
+
+* power: ``rte_power_set_env`` function will no longer return 0 on attempt
+  to set new power environment if power environment was already initialized.
+  In this case the function will return -1 unless the environment is unset first
+  (using ``rte_power_unset_env``). Other function usage scenarios will not change.
