Key Points

  • This release (1.14.4a1) includes multiple bug fixes to improve reliability, including handling crew chat description helpers when LLMs fail and resetting messages/iterations between executor invocations.
  • It fixes trained-agent behavior by forwarding custom trained-agents files through replay/testing in the CLI and honoring them during inference in the agent.
  • The update improves multimodal support by binding task-only agents to crews so that multimodal input files reach the LLM.
  • Guardrail and routing internals were adjusted for safer checkpointing and to prevent self-referential router behavior, including serializing guardrail callables as null and renaming force_final_answer.
  • It also bumps litellm for an SSTI fix and updates documentation with new sandbox tools and guides (E2B, Daytona, Vertex AI workload identity, and You.com MCP).
