This update introduces the M8 milestone, adding the A2A (Agent-to-Agent) protocol server and a sandboxed execution environment. The new A2AServer enables unified interface support (REST, MCP, and A2A) through the AgentRegistry, while the local runSandboxed utility provides a memory-capped, time-limited environment for executing untrusted code via Node.js worker threads. This milestone includes comprehensive testing across protocol endpoints and sandbox safety constraints.
