patch
LangGraph version 1.2.7 addresses critical issues related to delta channel overwrites and ensures valid UUID generation for exit-mode delta task IDs. These fixes improve the stability and reliability of state management within the graph execution, particularly for complex scenarios involving JSON roundtrips and API interactions. The release also includes dependency updates for libraries like redis and langsmith, affecting users of those components.
