GraphRAG 1.3

The GraphRAG Workflow Change Log provides an overview of changes made to the workflows specifying the affected workflows, change type and whether the change is breaking or not. In the last column Migration notes you will find further relevant details.

Change	Affected workflows	Type	Breaking change?	Migration notes
Hidden labels and concept scheme details of concepts were added	Configuration Fetch Concept Details	Bug fix	No	`skos:hiddenLabel` and `skos:inScheme` are now enabled by default as `conceptProperties` in the Configuration workflow
The Fetch Concept Details workflow is now usable as a standalone webhook	Fetch Concept Details Step - Graph Modeling Concept Enricher - Sync	Improvement	No	-
Various configuration variables and workflows were renamed for clarity	Configuration Error - Async, Error - Sync Main Parallel - Main, Parallel - Steps Batching Parallel Post Final Answer - Main Step - Final Answer - Sync Step - GraphDB MCP - Async Step - Input guardrails - Main Step - Vector Search - Async Utils - Calculate LLM usage Vector search tool	Bug fix	No	Typos in configuration variables were fixed (e.g. `parallelStepMaxTiemout` -> `parallelStepMaxTimeout`, `vectorStoreCustomMappins` -> `vectorStoreCustomMappings`)
Explainability messages with MCP and vector search `executionId`s were added for testing and evaluation purposes	Parallel - Main, Step - GraphDB MCP - Async Step - Vector Search - Async	Improvement	No	-
Custom concept properties to be added to the LLM context can now be defined	Configuration Fetch Concept Details	Improvement	No	A new configuration variable `conceptPropertyLlmContext` was introduced in the Configuration workflow to be able to add any custom concept properties to the LLM context
The authentication method in all Graph Modeling requests is now OAuth2 replacing Basic Auth	Fetch Concept Details Step - Graph Modeling Concept Enricher - Sync Step - Graph Modeling Expansion - Async Credential Graph Modeling	Improvement	Yes	The Graph Modeling user's credential were replaced with Oauth2 credentials which require setting up a GraphRAG client in the Keycloak instance used by Graph Modeling (refer to the Custom Keycloak Client section for more details on how to set up the GraphRAG client in Keycloak)Custom Keycloak Client
The n8n API key data table was converted to a credential	Error - Async Error - Sync Utils - Calculate LLM usage	Improvement	Yes
Improved structured output parsing reliability across workflows by adding fallback JSON handling for models that struggle with schema enforcement (for example, gpt-5.6-terra)	Configuration, LLM call Step - Final Answer - Sync	Improvement	No
The MCP protocol for connecting to the GraphDB MCP server was changed from SSE to HTTP Streamable	Step - GraphDB MCP - Async	Improvement	Yes	The GraphDB instance used for GraphRAG no longer requires the flag `graphdb.mcp.transport.mode=sse`. The `graphDBMcpUrl` is by default "`http://graphdb-host:port/mcp`" In the Configuration workflow.
