CrewAI 1.10.2 Alpha Fixes Critical Production Blockers: LockException Under Multi-Process Concurrency, Parallel MCP Tool Aggregation Race
CrewAI released 1.10.2a1 targeting the three failure modes that block production multi-agent deployments: LockException under multi-process concurrency, parallel tool result aggregation races, and ContextVars failing to propagate across threads in MCP tool execution. The release also patches a GitPython security CVE and adds Brave Search tool extensions. With 44.6K GitHub stars and 12M+ monthly PyPI downloads, these fixes are high-impact for teams running CrewAI orchestration in parallel — the concurrency bugs specifically prevented stable production deployments despite successful single-threaded demos.
