- NEW Framework examples and guides now cover LangGraph and Agent Framework explicitly, with CrewAI and LlamaIndex surfaced more clearly.
- NEW Live golden-path verification now covers proxy, MCP, unified sessions, LangGraph, Agent Framework, CrewAI, and LlamaIndex.
- NEW Session evidence can now be copied as a readable summary or exported as JSON from the dashboard.
- NEW Trust and security-review docs now describe the current pilot-ready posture more honestly.
v0.6.0 — March 9, 2026
