LangGraph 1.2.12 improves subgraph detection and adds interrupt response schema

sdkaigaengineerpython-agentic
feature patch

LangGraph version 1.2.12 introduces a new `response_schema` parameter to the `interrupt()` method, providing developers with more explicit control over interrupt handling in agent workflows. This release also includes a significant fix that enhances subgraph detection by analyzing bytecode instead of source code, improving accuracy and stability. Additionally, it addresses an issue with undeclared V3 stream projection types and updates several dependencies. These changes benefit engineers building and maintaining sophisticated agentic systems with LangGraph.
