langgraph 0.3.13

Summary of Changes

• Improved graph visualization with parallel traversal of subgraphs and support for RemoteGraph instances (#3879)
• Enhanced interrupt handling with better support for multiple concurrent interrupts and more robust error management (#3886)

Detailed Changes

langgraph.graph.graph.CompiledGraph

• Significantly improved the async graph visualization by implementing parallel traversal of subgraphs using asyncio.gather() (#3879)
• Added support for RemoteGraph visualization in both sync and async methods (#3879)
• Refactored code to extract common graph drawing logic into a new _draw_graph() method to reduce duplication (#3879)

langgraph.pregel.loop.PregelLoop

• Fixed interrupt emission to prevent duplicate events in the loop execution (#3886)
• Improved handling of sequence vs single interrupts to ensure proper propagation (#3886)

langgraph.pregel.runner.PregelRunner

• Enhanced handling of multiple concurrent interrupts by collecting and combining them into a single interrupt (#3886)
• Optimized the storage of interrupts in checkpoints (#3886)

langgraph.pregel.debug

• Fixed the debug visualization to properly handle interrupts that can be either single values or sequences (#3886)

langgraph.pregel.io

• Made task ID validation more robust by catching any exception during UUID parsing instead of just ValueError (#3886)
