langgraph-checkpoint 2.0.14

Summary of Changes

• Performance improvements and bug fixes for AsyncBatchedBaseStore to better handle async operations queuing, detect orphaned tasks, and improve error handling (PR #3445)

Detailed Changes

langgraph.store.base.batch.AsyncBatchedBaseStore

• Replaced dictionary-based operation queue with a proper asyncio.Queue for more reliable operation batching
• Added assertions to detect when operations are queued after the processing task has terminated
• Completely redesigned the async operation runner to:
  • Properly batch operations scheduled in the same event loop tick
  • Eliminate polling via asyncio.sleep(0) in favor of queue-based waiting
  • Improve error handling and resource cleanup
  • Fix potential race conditions in the original implementation
