Release Notes

GraphDB release notes provide information about the features and improvements in each release, as well as various bug fixes. GraphDB’s versioning scheme is based on semantic versioning. The full version is composed of three components:

major.minor.patch

e.g., 9.11.2 where the major version is 9, the minor version is 11 and the patch version is 2.

Occasional versions may include a modifier after a hyphen, e.g., 10.0.0-RC1 to signal additional information, e.g., a test release (TR1, TR2 and so on), a release candidate (RC1, RC2 and so on), a milestone release (M1, M2 and so on), or other relevant information.

Note

Releases with the same major and minor versions do not contain any new features. Releases with different patch versions contain fixes for bugs discovered since the previous minor. New or significantly changed features are released with a higher major or minor version.

GraphDB 10 includes the following components with their version numbers:

  • RDF4J

  • GraphDB Connectors

  • GraphDB Workbench

Their versions use the same semantic versioning scheme as the whole product, and their values are provided only as a reference.

2.3.0

GraphDB 10.3 introduces several exciting new features. One notable addition is the integration of ChatGPT, a popular Large Language Model, which greatly assists users in comprehending SPARQL queries and results, while also providing a new mechanism to enrich their RDF data. The upgrade of Ontop to version 5 significantly reduces the time and effort required to construct a knowledge graph from existing data sources by bringing new features and support for popular data management platforms like Dremio, Databricks and Snowflake. Furthermore, upgraded versions of the Elasticsearch and Solr connectors, along with a new dedicated OpenSearch connector, offer users better flexibility for indexing and searching their data. Additionally, GraphDB 10.3 includes numerous other improvements and bug fixes, further enhancing the overall user experience and stability of the system.

Important

Seamless integration with Large Language Models

GraphDB 10.3 features an innovative integration with ChatGPT, one of the most popular Large Language Models. This groundbreaking feature aims to revolutionize the way users interact with RDF and unlock its full potential for both newcomers and experienced users.

With the integration of ChatGPT, a powerful tool, users will now be able to delve into the world of RDF with greater ease and gain a deeper understanding of its capabilities. Whether you’re just starting out or have advanced knowledge, this integration empowers you to leverage ChatGPT’s capabilities and seamlessly integrate them with your RDF data to extract valuable insights.

One of the most significant aspects of this integration is the ability to explain queries and/or results with the assistance of ChatGPT. This feature ensures that users not only obtain accurate and relevant answers but also gain a comprehensive understanding of the underlying query logic and the significance of the obtained results. Such explanations foster a more informed decision-making process and empower users to extract maximum value from their RDF datasets.

Furthermore, GraphDB now provides the ability to pose generic questions to ChatGPT directly from SPARQL. By doing so, users can enrich their graphs and extract additional information from their data. This novel approach brings a new level of interactivity and intelligence to your RDF queries, opening up endless possibilities for knowledge discovery.

Integration with data management platforms

We understand that data projects often begin with existing information sources that employ non-semantic data models or are too large to be replicated. This can pose challenges for users and limit their confidence in building a robust knowledge graph from these sources.

To address this, we have made substantial advancements in integrating GraphDB with various external data sources, enabling seamless connectivity and simplifying knowledge graph construction. In particular, the upgrade to Ontop 5 brings expanded integrations with well-known platforms such as Dremio, Databricks, and Snowflake. These integrations have been carefully designed to streamline the process of incorporating data from these platforms into your knowledge graph.

By harnessing the power of GraphDB’s upgraded Ontop integration, users can now enjoy reduced time and effort when building their knowledge graphs. This means you can focus more on extracting insights and deriving value from your data, rather than struggling with complex data integration challenges.

Connectors for the world

We also understand that many of you rely heavily on external managed services such as Elasticsearch and Solr. In response to the growing demand and the need to upgrade to the latest major versions, we have upgraded the Elasticsearch and Solr connectors in GraphDB to the latest client versions. This ensures seamless compatibility and empowers you to leverage the advanced features and improvements offered by the latest major releases.

In addition, we have recognized the rising popularity of OpenSearch as an alternative to Elasticsearch. Since the two platforms have diverged substantially, we have taken a proactive approach to provide a dedicated implementation for OpenSearch. This dedicated connector implementation will enable you to seamlessly integrate OpenSearch into your GraphDB workflow, giving you greater flexibility and options for indexing and searching your data and all of the features of the Elasticsearch connector.

Stay up-to-date with the latest versions of third-party libraries

As a general strategy to offer a secure and reliable product, we strive to provide up-to-date versions of third-party libraries. This includes both features and bug fixes provided by the libraries and also addresses newly identified public vulnerabilities.

The RDF4J library in GraphDB was upgraded to 4.3.3 and brings a number of SHACL improvements and general bug fixes.
