Hangzhou – September 10, 2026 -- FastGPT, an open-source AI orchestration platform, has released multiple updated versions -- v4.8.10, v4.9.2 and v4.16.0 -- adding conditional workflow logic and revised self-hosted deployment requirements.
New user selection node enables Confirm/Cancel branching in workflows
The update introduces a user selection node allowing conditional branching via Confirm/Cancel prompts, though the feature is limited to workflow use and incompatible with plugins, tool calls, or Debug mode. Additional workflow changes include automatic edge and center alignment for dragged nodes, local editing history with undo/redo shortcuts, and workflow version renaming. Migrated application call nodes, plugin usage description configuration, and HTTP node support for text/plain mode and timeout settings round out the design updates.
Deployment overhaul deprecates E2B variables, mandates migration scripts
FastGPT revised image tags for its core and commercial services and updated environment variables governing sandbox proxy and resource limits, deprecating E2B-related variables in the process. Existing users running Agent Sandbox data must apply mandatory migration scripts to remain compatible with the new configuration. The platform also added knowledge base chunking optimizations with custom delimiters and larger chunk sizes, SSO migration support, and community-contributed database migration tutorials.
Cross-origin sandbox deployment recommended but not enforced
FastGPT flagged that some features depend on specific deployment environments and strongly recommended cross-origin sandbox deployment to limit security exposure, while noting no origin isolation check is enforced. Community-reported issues -- including loop node termination failures and code sandbox startup errors on certain Synology DSM kernels -- remain unresolved in this release cycle.
