langgraph-checkpoint-sqlite==3.1.2
This release updates the checkpointing logic to treat empty checkpoint IDs as the latest entry in delta history and enforces namespace label validation before store dispatch. It also improves delta channel replay ordering and optimizes ancestor traversal using parent pointers.
Verified State Diff
Impact & Verification Analysis
Developers building stateful agentic workflows using LangGraph with SQLite or Postgres backends.
These changes improve the reliability of state persistence and recovery, reducing the likelihood of corrupted or ambiguous state transitions in long-running agentic processes.
Full Fact Overview
Version 3.1.2 of langgraph-checkpoint-sqlite introduces critical refinements to state management and persistence. The update addresses ambiguity in delta history retrieval by defaulting empty checkpoint IDs to the latest state, ensuring more predictable recovery. Furthermore, it implements strict validation for namespace labels prior to store dispatch, reducing potential runtime errors in multi-tenant or complex graph architectures. The inclusion of parent-pointer-based ancestor walking and task-path-based replay ordering indicates a focus on stabilizing the underlying state machine's consistency during complex graph execution.
