# Lambda Runtime Extension

## 1.13.0 - 16<sup>th</sup> September

### Updates

#### Shutdown reason logging

The extension now logs the explicit shutdown reason it receives from the AWS Lambda runtime. This gives you deeper visibility and makes it easier to troubleshoot when a function terminates or times out unexpectedly.

### Resolved Issues

#### Fixed a race condition during shutdown

Resolved a potential race condition in the extension's shutdown sequence, so the extension now terminates gracefully and flushes all outstanding logs and telemetry before exiting.
