16 Commits • 7 Features
Mar 1, 2026During March 2026, delivered cross-region and machine-type configuration across CLI and framework, enabling region-aware app filtering, region validation in FalServerlessHost, and CLI support for machine types. Improved authentication and access control with team-scoped FAL_KEY usage and clearer API key ownership feedback. Introduced a max-requests cap to improve resource governance and predictability. Refactored runtime concurrency with async context management in DistributedRunner for better reliability. Modernized the toolkit with async File methods and removed the experimental fal.toolkit.optimize module to stabilize tooling. Stabilized dependencies and CI: relaxed constraints for isolate, added uv exclude-newer, and updated CI to use development FAL_KEY in end-to-end and integration tests. CI/test timing tweaks and timeouts were adjusted to improve stability.

Oct 1, 2025October 2025 delivered a suite of platform enhancements that streamline deployments, improve observability, and strengthen reliability for Fal. Key features shipped include a new Fal CLI that streams logs with filtering options and supports recursive remote file removal, declarative app configuration via class variables, and a new SyncServerlessClient with a team-aware deployment workflow and API refactor. We also added per-request header support in the Fal client to enable tracing and metadata propagation. In addition, reliability and correctness were improved through fixes to app discovery (excluding the base fal.App), app name generation/host argument propagation, and tblib compatibility to ensure stable exception handling. These changes collectively reduce misconfigurations, accelerate team-led deployments, and enhance developer productivity and operational reliability.
