--- fixes: - | Since microversion 1.34, it has been possible to provide a ``mappings`` field when creating new allocations via the ``POST /allocations`` or ``PUT /allocations/{allocation_id}`` APIs. This field should be a a dictionary associating request group suffixes with a list of UUIDs identifying the resource providers that satisfied each group. Due to a typo, this was allowing an empty object (``{}``). This is now corrected.
