+We're excited to release MassGen v0.1.64 β Gemini CLI Backend! π MassGen now supports Google's Gemini CLI as a backend with session persistence, MCP tools, and Docker support. Plus: WebSocket streaming for OpenAI Response API, execution trace analyzer subagent, and Copilot Docker mode.
+
+**Key Improvement:**
+
+π **Gemini CLI Backend** - Google's Gemini CLI as a native MassGen backend:
+- Subprocess-based integration with Gemini 2.5 and 3.x model families
+- Session persistence via CLI session IDs for multi-turn conversations
+- MCP tools wired through `.gemini/settings.json` configuration
+- Docker support for containerized execution
+
+**Plus:**
+- β‘ **WebSocket streaming** β persistent `wss://` transport for OpenAI Response API with auto-reconnection and real-time event streaming
+- π **Execution trace analyzer** β new subagent type for mechanistic analysis of agent execution traces with 7-dimension evaluation framework
+- π³ **Copilot Docker mode** β containerized tool execution for Copilot backend with sudo and network configuration
+- π§ **Response API fix** β prevent duplicate item errors in recursive tool loops
+
+**Getting Started:**
+
+```bash
+pip install massgen==0.1.64
+# Try the Gemini CLI backend
+uv run massgen --config @examples/providers/gemini/gemini_cli_local "Explain quantum computing"
+```
