GraphDB 11.2.0 Release Notes

27/11/2025

GraphDB 11.2 introduces significant new features and critical bug fixes, improving on the LLM and AI capabilities of GraphDB. Key updates include vector search in Elasticsearch GraphDB Connector and OpenSearch GraphDB Connector, enhancements to the similarity search method in Talk to Your Graph, support for Google Vertex and AWS Bedrock in Talk to Your Graph, a new native Python client with full support for the RDF4J API, and improved conformance to SPARQL 1.1. To improve stability and performance, this release also fixes several major bugs affecting GraphQL, MCP support, and cluster replication.

Additionally, GraphDB 11.2 includes numerous bug fixes and smaller improvements, enhancing overall product stability and user experience. The versions of several external components and connectors have also been updated — check the Migrating GraphDB configurations page for more details.

The development of the features in this release was partially funded by the EnrichMyData (GA nu: 101070284) Horizon Europe research project.

Vector search in Elasticsearch and OpenSearch
GraphDB 11.2 introduces support for vector search in Elasticsearch GraphDB Connector and OpenSearch GraphDB Connector, which enables semantic similarity to ensure better recall than full-text search. This allows AI agents to find entities similar to text in a GraphRAG environment using vector indexes that are automatically updated with the data. This improves the existing Semantic similarity searches, solving its major limitation - the lack of automatic updates.
The vector search uses embeddings created by an embedding model client configured in the connector. The new Graphwise Transformer tool provides a way to deploy any Hugging Face Sentence Transformer model that you can use to create these embeddings. In addition to that, when using Elasticsearch you can create the embeddings in Elasticsearch using Elasticsearch ML features.
Talk to Your Graph Semantic Similarity improvements
The vector search capabilities in Elasticsearch and OpenSearch connectors introduced with GraphDB 11.2 are also available in Talk to Your Graph. The SimilaritySearchTool tool now supports both GraphDB’s native similarity indexes and the vector-based external connector (Elasticsearch and OpenSearch) with vector-based search over specified fields. Previously, similarity queries in Talk to Your Graph were limited to GraphDB’s built-in similarity indexes.
Managing access to Repositories with dynamic names using LDAP
GraphDB now supports * wildcards in repository role mappings. This allows administrators to grant read and write access to repositories that are dynamically created, removed and recreated by automated processes at runtime. The wildcard support circumvents the need to update the config for every new repository.
