Added support for transactional operations over a session, using the edit cache, that can be saved or discarded when the session completes. See GraphQL Extensions.
Added support for generically querying data model extensions (DMEs) in the schema. Currently, DMEs are only available for selected customers. The schema extensions can be used (although not recommended) to query the core data model too. See GraphQL Extensions.
Using the value argument but without the filter argument in an update mutation now returns a warning (as part of extensions) because it may lead to unintentional updates of multiple records. This will become an error in the future.
