#2914840: Add support for 'classmap' and 'files' autoload types
Reverts support for persisted queries. After further analysis, it's been detected that persisted queries can return a DocumentNode, which makes impossible to load any fragment include (since they are simply strings).
We recommend trying https://www.drupal.org/project/graphql_apq which should take the parsed query with all fragments loaded and properly store it in the query map.
Fixed duplicates triples when update a node
Fixed an issue with the multi response separator.
