features:
- |
Adds functionality with neutron integration to support dual-stack
(IPv4 and IPv6 environment configurations). This enables ironic to
look up the attached port(s) and supply DHCP options in alignment
with the protocol version allocated on the port.
upgrade:
- |
The ``[pxe]ip_version`` setting may no longer be required depending on
neutron integration.
- |
Operators that used the ``[DEFAULT]my_ip`` setting with an IPv6 address
may wish to explore migrating to the ``[DEFAULT]my_ipv6`` setting. Setting
both values enables the appropriate IP addresses based on protocol version
for PXE/iPXE.
