Version 4.16.0 and Patch Updates Add Conditional Workflows, Sandbox Configuration, and Migration Guides
HANGZHOU, China, Sept. 8, 2026 /PRNewswire/ — FastGPT, an open-source AI orchestration platform, has rolled out multiple updated versions including v4.8.10, v4.9.2, and v4.16.0, with targeted improvements for workflow design and self-hosted deployment.
Core workflow updates include automatic edge and center alignment for dragged nodes, a user selection node that enables conditional branching via Confirm/Cancel prompts (limited to workflow use, incompatible with plugins or tool calls, with Debug mode unsupported), local editing history with undo/redo shortcuts, and workflow version renaming. Additional changes include migrated application call nodes, plugin usage description configuration, and HTTP node support for text/plain mode and timeout settings.
Deployment adjustments include revised image tags for core and commercial services, updated environment variables for sandbox proxy and resource limits (with E2B-related variables deprecated), and mandatory migration scripts for existing Agent Sandbox data. The platform also adds knowledge base chunking optimizations with custom delimiters and larger chunk sizes, SSO migration support, and community-contributed database migration tutorials.
Notable limitations include that some features depend on specific deployment environments; cross-origin sandbox deployment is strongly recommended to avoid security risks, though no origin isolation check is enforced. Known community-reported issues, such as loop node termination failures and code sandbox startup errors on certain Synology DSM kernels, are not covered in this update.
FastGPT is hosted on GitHub, with full release notes and documentation available at its official repository. Self-hosted users should review official upgrade guides prior to deploying updates.
