3 - The ``NeutronExternalNetworkBridge`` parameter changed its default value
4 from ``br-ex`` to an empty string value. It means that by default Neutron
5 L3 agent will be able to serve multiple external networks. (It was always
6 the case for those who were using templates with the value of the parameter
7 overridden by an empty string value.)
9 - The ``NeutronExternalNetworkBridge`` parameter is deprecated and will be
10 removed in a next release.
