Tip: Upgrade to Claude Code v2.1.79 to Fix claude -p Subprocess Hang in Python CI/CD
Releasebot·medium signal
Claude Code v2.1.79 resolves a critical bug where claude -p hung indefinitely when spawned as a Python subprocess without explicit stdin (e.g. subprocess.run). Ctrl+C was also non-functional in -p mode. Builders using headless Claude Code in CI/CD pipelines or orchestration scripts should upgrade immediately. The same release fixes SessionEnd hooks not firing when using interactive /resume — important for hook-based session tracking.
