August 2025: Delivered security-first access control with granular permissions and default policy enforcement, improved internal argument handling through a BoundArg refactor, and expanded multi-schema support and ORM testing in gel-python. Implemented a query refetch argument structure, added per-schema model generation workflows, and grew the test suite with comprehensive synchronization tests and a bug fix to ensure multi-valued properties clear after synchronization. These changes reduce security risk, enhance developer productivity, and provide a scalable foundation for multi-tenant deployments across Gel and Gel-Python.
