langgraph 0.2.36

Summary of Changes

• Added support for remote LangGraph deployments with new RemoteGraph class to interact with hosted graphs via LangGraph API (#2078, #2085)
• Introduced PregelProtocol, defining a standard interface for interacting with graphs (#2078)
• Enhanced task handling by adding a result field to PregelTask to support returning task results (#2078)
• Fixed several bugs in internal Pregel engine, improving interrupt handling and state management

Detailed Changes

langgraph.pregel.protocol.PregelProtocol

• Added new protocol class that defines the standard interface for interacting with graphs
• Includes methods for state management, graph visualization, subgraph traversal, and execution
• Provides both synchronous and asynchronous versions of methods for flexibility

langgraph.pregel.remote.RemoteGraph

• Added new class for interacting with remote LangGraph deployments
• Implements the PregelProtocol interface
• Supports all operations available on local graphs: invoking, streaming, state inspection, visualization
• Provides configuration options for connecting to LangGraph API with authentication

langgraph.types.PregelTask

• Added result field to store task execution results
• Enables tasks to return structured data that can be accessed in state snapshots
• Improves the ability to track and analyze task outcomes

langgraph.pregel.Pregel

• Improved copy() method to handle None values correctly
• Fixed interrupt handling in the internal Pregel engine
• Enhanced state snapshot creation to include output information
• Improved error handling during state updates
