0.2.47

langgraph 0.2.47

Summary of Changes

• Added a new interrupt() function that supports resumable interrupts, allowing for more flexible control flow in graphs
• Enhanced the Command class with a new resume parameter to resume execution after an interrupt
• Added support for handling writes that are not associated with a specific task through the NULL_TASK_ID constant
• Improved task scheduling by supporting pushing tasks during execution
• Enhanced state update mechanism by separating PUSH writes from channel writes

Detailed Changes

langgraph.types.interrupt

• Added a new utility function to handle interrupts with resumability
• Allows nodes to be interrupted and later resumed with specific values
• Creates interrupts with proper namespace tracking for accurate resumption

langgraph.types.Command

• Refactored from a regular class with slots to a dataclass for better maintainability
• Added a new resume parameter to control resumption after an interrupt
• Enhanced with better string representation methods

langgraph.constants.RESUME

• Added new constant to identify values used to resume a node after an interrupt

langgraph.constants.NULL_TASK_ID

• Added new constant to use for writes that are not associated with a task
• Enables better handling of "global" writes that should be applied independently of task execution

langgraph.graph.state.GraphCommand

• Updated to a dataclass with improved representation methods
• Maintains compatibility with the enhanced Command class

langgraph.errors.NodeInterrupt

• Updated constructor to use keyword arguments for better clarity
