+ their behavior will be kept until 17.02 and will be removed in 17.05.
+
+* ethdev: the legacy filter API, including
+ ``rte_eth_dev_filter_supported()``, ``rte_eth_dev_filter_ctrl()`` as well
+ as filter types MACVLAN, ETHERTYPE, FLEXIBLE, SYN, NTUPLE, TUNNEL, FDIR,
+ HASH and L2_TUNNEL, is superseded by the generic flow API (rte_flow) in
+ PMDs that implement the latter.
+ Target release for removal of the legacy API will be defined once most
+ PMDs have switched to rte_flow.
+
+* vhost: API/ABI changes are planned for 17.05, for making DPDK vhost library
+ generic enough so that applications can build different vhost-user drivers
+ (instead of vhost-user net only) on top of that.
+ Specifically, ``virtio_net_device_ops`` will be renamed to ``vhost_device_ops``.
+ Correspondingly, some API's parameter need be changed. Few more functions also
+ need be reworked to let it be device aware. For example, different virtio device
+ has different feature set, meaning functions like ``rte_vhost_feature_disable``
+ need be changed. Last, file rte_virtio_net.h will be renamed to rte_vhost.h.
+
+* ABI changes are planned for 17.05 in the ``rte_cryptodev_ops`` structure.
+ A pointer to a rte_cryptodev_config structure will be added to the
+ function prototype ``cryptodev_configure_t``, as a new parameter.
