features:
- |
nvmet target driver: Added support to serve volumes on multiple addresses
using the ``target_secondary_ip_addresses`` configuration option. This
allows os-brick to iterate through them in search of one connection that
works, and once os-brick supports NVMe-oF multipathing it will be
automatically supported.
This requires that ``nvmeof_conn_info_version`` configuration option is set
to ``2`` as well.
deprecations:
- |
Configuration option ``iscsi_secondary_ip_addresses`` is deprecated in
favor of ``target_secondary_ip_addresses`` to follow the same naming
convention of ``target_ip_address``.
