+* ethdev: a new Tx and Rx offload API was introduced on 17.11.
+  In the new API, offloads are divided into per-port and per-queue offloads.
+  Offloads are disabled by default and enabled per application request.
+  The old offloads API is target to be deprecated on 18.05. This includes:
+
+  - removal of ``ETH_TXQ_FLAGS_NO*`` flags.
+  - removal of ``txq_flags`` field from ``rte_eth_txconf`` struct.
+  - removal of the offloads bit-field from ``rte_eth_rxmode`` struct.

   Target release for removal of the legacy API will be defined once most
   PMDs have switched to rte_flow.
 
+* i40e: The default flexible payload configuration which extracts the first 16
+  bytes of the payload for RSS will be deprecated starting from 18.02. If
+  required the previous behavior can be configured using existing flow
+  director APIs. There is no ABI/API break. This change will just remove a
+  global configuration setting and require explicit configuration.

 * librte_meter: The API will change to accommodate configuration profiles.
   Most of the API functions will have an additional opaque parameter.
+
+* ring: The alignment constraints on the ring structure will be relaxed
+  to one cache line instead of two, and an empty cache line padding will
+  be added between the producer and consumer structures. The size of the
+  structure and the offset of the fields will remain the same on
+  platforms with 64B cache line, but will change on other platforms.
