-    Fix bug 1693168. v2.1 API which does not return the ``server_groups`` and
-    ``server_group_members`` quotas in GET and PUT ``os-quota-class-sets`` API
-    response. v2 API used to return those keys in the API response.
-    Microversion 2.50 restored that behavior. In microversion 2.50, the
-    ``server_groups`` and ``server_group_members`` keys are exposed in
-    GET and PUT ``os-quota-class-sets`` APIs Response body.
-    Fix bug 1701211. Network related quotas are filtered out of
-    ``os-quota-class-sets`` APIs and not available from microversion
-    2.50 onwards.
-    Filtered quotas are:
+    In the 2.50 microversion, the following fields are added to the
+    ``GET /os-quota-class-sets`` and ``PUT /os-quota-class-sets/{id}`` API
+    response:
 
-    - 'fixed_ips'
-    - 'floating ips'
-    - 'security_groups'
-    - 'security_group_rules'
-    - 'networks'
+    - ``server_groups``
+    - ``server_group_members``

+    - ``floating_ips``
+    - ``security_groups``
+    - ``security_group_rules``
