langgraph-sdk 0.4.3 adds decrypt replacement result and fixes cron end_time handling
GitHub (langchain-ai/langgraph)·low signal
LangGraph shipped langgraph-sdk 0.4.3 on August 19, 2026, adding a decrypt replacement result path and pulling in changes from langgraph 1.2.11 along with checkpoint 4.2.0. It also resolves issues with cron end_time management, which matters for anyone running scheduled LangGraph deployments. This is maintenance-tier, notable mainly because the core langgraph package has not moved since 1.2.11 on August 11.
