fixes:
  - |
    Adds the ``router`` service plugin to the ``port_forwarding`` service
    plugin required list. For more info see

other:
  - |
    Neutron now supports having service plugins require other plugin(s) as
    dependencies. For example, the ``port_forwarding`` service plugin
    requires the ``router`` service plugin to achieve full functionality. A
    new list, ``required_service_plugins``, was added to each service
    plugin so the required dependencies of each service plugin can be
    initialized.  If one service plugin requires another, but the requirement
    is not set in the config file, neutron will now initialize it to the
    plugin directory.
upgrade:
  - |
    During the dependency resolution procedure, the code that loads service
    plugins was refactored to not raise an exception if one plugin is
    configured multiple times, with the last one taking effect. This is a
    change from the previous behavior.
