Claude Code 2.1.225 Fixes a Transient 401 That Silently Broke Headless Sessions Until Restart
Released August 8, 2026, version 2.1.225 fixes a bug where a transient 401 caused Claude Code to replace a long-lived `CLAUDE_CODE_OAUTH_TOKEN` with a stored login's short-lived token, breaking headless sessions until restart. It also fixes MCP OAuth servers on macOS intermittently failing with a burst of 401s after a keychain read timed out. Anyone running Claude Code in cron jobs, CI, or unattended pipelines should upgrade — these are exactly the failure modes that make an automated run die silently overnight.
