--- upgrade: - Flavors are being moved to the API database for CellsV2. In this release, the online data migrations will move any flavors you have in your main database to the API database, retaining all attributes. Until this is complete, new attempts to create flavors will return an HTTP 409 to avoid creating flavors in one place that may conflict with flavors you already have and are yet to be migrated. - Note that flavors can no longer be soft-deleted as the API database does not replicate the legacy soft-delete functionality from the main database. As such, deleted flavors are not migrated and the behavior users will experience will be the same as if a purge of deleted records was performed.
