Under the hood
Claude Code now flushes any held-back telemetry before it shuts down
What
When a session is shutting down, if telemetry events are currently being held back under the new server-served flush policy, Claude Code now applies a "shutdown" hold, keeps client events open through the cleanup process, and performs an extra flush before finally closing.
Why
This makes sure telemetry that was deliberately delayed for batching isn't accidentally lost when the app or session exits.
