langgraph 0.3.6

Summary of Changes

• Improved type annotations for task decorator to better handle async functions (#3670)

• Added support for input schema detection in branch paths for StateGraph (#2516)

Detailed Changes

langgraph.func.task

• Improved type annotations to consistently prioritize async functions in Union types, making the API more predictable (#3670)

langgraph.graph.branch.Branch

• Moved from graph.py to its own dedicated module for better organization (#2516)
• Added input_schema field to support automatic schema inference (#2516)
• Added factory method from_path that handles path_map conversion and optionally infers input schema (#2516)
• Enhanced passthrough behavior to only merge inputs with state when no input schema is defined (#2516)

langgraph.graph.state.StateGraph

• Added add_conditional_edges implementation that includes schema inference (#2516)
• Updated branch handling to use inferred schema when available, improving type safety (#2516)
