If your project uses neutron.extensions.extra_dhcp_opt please read on. The extra_dhcp_opt is now available as a neutron-lib API definition [1] and consumption has begun [2]. Recommended action: - If you're a stadium project; you should be covered in [2]. - If not, please update your project's imports to use the neutron-lib API def rather than the neutron extension. The work in [2] can be used as reference. We can discuss when to land the changes in neutron [3] during our weekly meetings.
