What's New
FastGPT enforces AI Proxy and adds SSO, while DSPy introduces Jev integration and native LM engines
Breaking Changes
- `interpreter_factory` is now keyword-only in DSPy
- FastGPT removes `OPENAI_BASE_URL` and `CHAT_API_KEY` environment variables
New Features
- Jev integration with typed decision types (Noul, Choice, Score)
- ReAnchor optimizer for calibrating decisions against metrics
- Native LM engines (`lm15`) and custom HTTP providers
- Local CPython interpreter for trusted code execution
- LDAP and DingTalk SSO synchronization
Improvements
- CSRF defense mechanism via environment variable
- Optional Code Sandbox seccomp compatibility configuration
- Automatic system upgrade task management with status tracking
- Default team permissions configuration for new teams
- Deprecation warnings for legacy custom-LM integrations
Upgrade Notes
FastGPT requires upgrading to v4.16.2 first and running legacy scripts, then configuring mandatory AI Proxy variables and removing deprecated OpenAI keys. DSPy 3.4 requires passing `interpreter_factory` as a keyword argument and installing the `typesafe` extra for Jev integration.
