FQL v4 will be decommissioned on June 30, 2025. Ensure that you complete your migration from FQL v4 to FQL v10 by that date. Fauna accounts created after August 21, 2024 must use FQL v10. These accounts will not be able to run FQL v4 queries or access the v4 Dashboard. For more details, see the v4 EOL announcement and migration guide. Contact support@fauna.com with any questions. |
Deprecations
This reference topic applies to FQL v4. Go to this page for the latest FQL v10 reference topics. |
As Fauna evolves, new features are added and, the focus of this section, older features are deprecated and slated for eventual removal.
Removing functionality that you depend on can affect your applications and their queries. Wherever possible, we evolve Fauna in a way that preserves compatibility with existing queries. Whenever that is not possible, we communicate the deprecation well in advance of the removal (at least 6-12 months after deprecation).
