Fine-Grained News - October 2025

Welcome to OpenFGA's Fine-Grained News, October edition!

🎉 OpenFGA to CNCF Incubation!

The CNCF completed the Due Diligence process to approve moving OpenFGA to the CNCF Incubation stage, and it's now open for comments. Support emojis are appreciated! 🚀 ❤️!

Thanks to Grafana, Docker, Read.AI, Agicap, and Zuplo for taking the time to talk to the CNCF about their experience!

Moving to the Incubation maturity level is great news for the OpenFGA community and we are super excited about it!

🚀 What We've Shipped

OpenFGA v1.10.0 Performance Improvements

Starting with OpenFGA v1.10.0, we've included a query planner that selects resolution strategies based on runtime statistics, behind the enable-check-optimization flag. The planner can pick different strategies per-relation, and we've seen significant improvements in performance for some models/relations. In-depth engineering blog post coming soon!

Write Endpoint Enhancements

In case you missed it, we also included in v1.10.0 two new (optional) parameters to the /write endpoint that allow specifying the expected behavior when duplicated tuples are written or non-existing tuples are deleted. The Go, Java, and .NET SDK already support them, and we'll be completing support for Python, and Javascript in the next few weeks.

SDK & Tooling Updates

• Go SDK 0.7.3 adds support for specifying custom headers per request, and for specifying conflict resolution options for Write operations. Also, v0.7.2 brings fixes to retry handling and other improvements, including allowing filtering stores by name and contextual tuples in Expand requests. Thanks to Oscar Evertsson and Cale Switzer for their contributions!

• .NET SDK 0.8.0 adds support for specifying custom headers per request, and for specifying conflict resolution options for Write operations. It builds on .NET SDK 0.7.0 that added support for .NET Standard 2.0, .NET 8 and .NET 9.

• Java SDK 0.9.2 adds support for specifying conflict resolution options for Write operations. It builds on Java SDK 0.9.1 which fixes issues when overriding request headers. Thanks to Oscar Evertsson and Vakart for their contributions!

• Python SDK 0.9.7 adds support for specifying custom headers per request, and v0.9.6 also includes some enhancements.

• CLI 0.7.5 simplifies retrieving all tuples and ignores duplicate writes when importing tuples from a file.

🌟 Community Spotlight

Read.AI, one of the earliest OpenFGA adopters, was recognized by OpenAI for processing 1 trillion tokens. They use OpenAI for RAG use cases powered by OpenFGA :).

Congrats to Luke Woloszyn, Andrew Powers, and Sam Matthews for such a great achievement!
