You'll notice
A telemetry failure can no longer block releasing the OAuth token refresh lock
What
When Claude Code releases its internal lock on refreshing an OAuth authentication token, it emits telemetry events for 'releasing' and, on error, 'release_error'. Both of these telemetry calls are now individually wrapped in their own error handling, so a failure in sending the telemetry itself can no longer prevent the lock from actually being released or the error from being logged.
Why
This is a reliability fix: previously, a telemetry hiccup during token refresh could interfere with releasing the lock or recording the error, which could affect authentication flows. Now the telemetry is best-effort and can't get in the way.
