prelude: >
    A new agent_mode(``dvr_no_external``) for DVR routers has been added
    to allow the server to configure Floating IPs associated with DVR at
    the centralized node.
features:
  - |
    A new DVR agent type ``dvr_no_external`` has been introduced with this
    release. This agent type allows the Floating IPs (DNAT/North-South routing)
    to be centralized while the East/West routing is still distributed.
issues:
  - |
    There can be a mixture of ``dvr`` agents and ``dvr_no_external`` agents.
    But please avoid any VM with Floating IP migration between a ``dvr`` agent
    and a ``dvr_no_external`` agent. All VM ports with Floating IPs should be
    migrated to same agent_mode.
    This would be one of the restrictions.
upgrade:
  - |
    A new DVR agent mode of ``dvr_no_external`` was added. Changing between
    this mode and ``dvr`` is a disruptive operation to the dataplane.
