+features:
+  - Support added for configuring metadata about networks
+    for a cloud in a list of dicts, rather than in the
+    external_network and internal_network entries. The dicts
+    support a name and a routes_externally field, as well as
+    any other arbitrary metadata needed by consuming
+    applications.
+deprecations:
+  - external_network and internal_network are deprecated and
+    should be replaced with the list of network dicts.
