Less than a month after its introduction, the edition field on both Cluster and Backup schemas, along with its enum values, has been deprecated. This rapid deprecation requires developers who adopted this field to update their code to no longer rely on it. Instead, for backups of Express clusters, the new expressConfig property has been added to the Backup schema. This expressConfig property is output-only (readOnly), meaning it reflects the configuration of the source cluster but cannot be set or modified directly. This immutability is considered a breaking change if you were anticipating setting this new property, as indicated by the API's breaking reasons.
