Claude Code v2.1.203–v2.1.204: background session fixes and hook streaming repair
Anthropic
Two Claude Code releases shipped July 7–8: v2.1.203 fixed macOS background session stalls (15–20 s false low-memory trigger), Windows PATH inheritance in background agents, and added login-expiry warnings with a manual-permission pause badge. v2.1.204 fixed hook events not streaming during headless SessionStart hooks, which caused remote workers to be idle-reaped mid-hook.
Why it matters
The hook-streaming fix and session-recovery patch close silent failure modes that affect CI/CD and remote-worker deployments where background agent health is unattended.
Importance: 2/5
