What changed

  • Hooks can fail closed. Command and HTTP hooks accept onFailure: "block": a hook that can't start, times out, or exits with an unexpected code blocks the action instead of letting it through.
  • Terminal status. Terminals that implement the Program Status Protocol (OSC 7501) can show whether Claude Code is working, waiting on you, or done.
  • Gateway upstream controls. The Claude apps gateway gains timeouts.upstream_ttfb_ms for cloud upstreams and an optional models list per upstream, where only listed models are sent, including on failover.
  • Gateway observability. The inference audit event now carries upstream_request_id, and successful inference responses include a request-id header so telemetry request_id matches the audit log.
  • MCP reliability fixes. Remote MCP servers in headless and SDK sessions now back off up to 30s on repeated drops, and repeated pagination cursors no longer cause up to 20 requests for the same page at every connect.
  • Headless output. claude -p now prints each turn's response when the turn ends, and prints a stderr line saying what a run is waiting for when it stays open.

Questions

Does a failing hook now stop the action?
