Welcome to the second Fine-Grained News edition of 2025!

Just Shipped!​

• We shipped 3 minor versions of OpenFGA which include:

  • Fixes for CVE-2025-25196 and CVE-2024-56323

  • Several performance improvements that are enabled with the enable-check-optimizations experimental flag.

  • Dynamic TLS certificate reloading for HTTP and gRPC servers. Thanks Rokibul Hasan for your contribution!

  • A name filter to ListStores. The name parameter instructs the API to only include results that match that name. Thanks Karl Persson for your contribution!

  • Optimized database dialect handling by setting it during initialization instead of per-call, fixing SQL syntax errors in MySQL. Thanks Siddhant Khare for your contribution!

  • Support for Go 1.24. We follow Go's version support policy and will only support the latest two major versions of Go. Now that Go 1.24 is out, we have dropped support for Go < 1.23.

• Two minor versions of the Java SDK, with support for server-side BatchCheck. Thanks Piotr Olaszewski for your contribution!

• A minor release of the Go SDK, with support for the StartTime parameter in the ReadChanges method and support for specifying contextual tuples and context parameters in assertions.

• A minor release of the FGA CLI, with support for the start-time parameter for the changes command and importing assertions during fga store import. Thanks Sujitha A V for your contribution!

Using OpenFGA for GenAI and Retrieval Augmented Generation (RAG)​

• Building a Secure RAG with Python, LangChain, and OpenFGA
• GenAI, LangChain.js, and FGA
• Building a Permissions System For Your RAG Application

OpenFGA to CNCF Incubation​

The CNCF Technical Oversight Committee triaged OpenFGA's application to be accepted as an "Incubation" project, decided we had provided the appropriate information and references, and moved the project to the next step. We now need to wait for a TOC member to pick the project and do their due diligence.

Thanks to Canonical, Grafana, Docker, Read.AI, Agicap, Sourcegraph, Zuplo, and Stacklok for agreeing to be interviewed by the CNCF as reference adopters!

OpenFGA will be present in two high-profile events in London:

• Sam Bellen will participate in the Gartner IAM EMEA event demoing OpenFGA interoperability with the AuthZen standard.

• Poovamraj Thanganadar Thiagarajan from Okta will be presenting at KubeCon Europe, together with Jo Guerreiro from Grafana Labs about From Chaos To Control: Migrating Access Control To OpenFGA in a Multi-Tenant World.

• Andres Aguiar from Okta was invited to present on the Maintainer's Summit at KubeCon Europe about our experiences collaborating with the CNCF TAG-Security team: A Project Maintainers Guide To TAG Security.
