+> [!NOTE]
+> **New in LangGraph v0.6**: [LangGraph Context](https://docs.langchain.com/oss/python/context#context-overview) replaces the traditional `config['configurable']` pattern. Runtime context is now passed to the `context` argument of `invoke/stream`, providing a cleaner and more intuitive way to configure your agents.

+- **Context-Driven Configuration**: Runtime context passed via `context` parameter instead of `config['configurable']`
+- **Simplified API**: Cleaner interface for passing runtime configuration to your agents
+- **Backward Compatibility**: Gradual migration path from the old configuration pattern
