    Microversion 2.55 adds a ``description`` field to the flavor resource in
    the following APIs:

    * ``GET /flavors``
    * ``GET /flavors/detail``
    * ``GET /flavors/{flavor_id}``
    * ``POST /flavors``
    * ``PUT /flavors/{flavor_id}``

    The embedded flavor description will not be included in server
    representations.

    A new policy rule ``os_compute_api:os-flavor-manage:update`` is added
    to control access to the ``PUT /flavors/{flavor_id}`` API.
