Add a word about the new GraphQLConfiguration class
@@ -6,6 +6,7 @@ Client mode:
* The support for the _withField()_, _withSubObject()_ (...) methods has been removed
* The ___IntrospectionQuery_ class is no mode generated: the ___schema_ and ___type_ queries has been added to the GraphQL schema's query, as defined in the GraphQL spec. A default query is added if no query was defined in the GraphQL schema.
* The client code should now use the _GraphQLRequest_ that is now generated along with the GraphQL java classes.
+ * A _GraphQLConfiguration_ class has been added. The generated query/mutation/subscription classes create an instance of this class, so there is no impact on existing code. But this class must be used to configure the _GraphQLRequest_.
* Please check the behavior of your full queries: the mutation keyword is now mandatory for mutations, as specified in the GraphQL specification. The query keyword remains optional.
* Please the [client mode doc](https://graphql-maven-plugin-project.graphql-java-generator.com/client.html) for more information.
