FQL v4 will be decommissioned on June 30, 2025. Ensure that you complete your migration from FQL v4 to FQL v10 by that date.

For more details, see the v4 EOL announcement and migration guide. Contact support@fauna.com with any questions.


v10 is the current version of FQL, which is designed to simplify and improve the developer experience. The v10 release also includes:

  • New FQL v10 client drivers.

  • An upgraded Fauna Dashboard experience.

  • Fauna Schema Language (FSL), a data definition language you can use to manage your database schema as code.

v4 is still supported, but Fauna will only release new features and functionality to v10.
