--- features: - | Added microversion v2.40 which introduces pagination support for usage with the help of new optional parameters 'limit' and 'marker'. If 'limit' isn't provided, it will default to the configurable max limit which is currently 1000. :: /os-simple-tenant-usage?limit={limit}&marker={instance_uuid} /os-simple-tenant-usage/{tenant}?limit={limit}&marker={instance_uuid} Older microversions will not accept these new paging query parameters, but they will start to silently limit by the max limit to encourage the adoption of this new microversion, and circumvent the existing possibility DoS-like usage requests on systems with thousands of instances.
