The crewAI team released version 1.15.7, introducing bug fixes for tool calling and a security patch alongside new observability features.
Key changes include resolving registry skills through the runtime's CrewAI+ client and fixing tool calling on the Responses API path. The update also routes responses-only models to prevent 404 errors and recovers from GPT-5.6 tools with reasoning_effort 400. Additionally, it bumps bedrock-agentcore to patch CVE-2026-16796 and emits skill usage events at runtime for observability.
This release improves stability for specific API interactions and enhances monitoring capabilities through new event emissions.
