This release includes improvements to logging stability and performance.

### Bug Fixes 🐛

- **Fixed OpenTelemetry fetch instrumentation issue** - Resolved an issue with
  OpenTelemetry outgoing fetch instrumentation that could cause unexpected
  behavior in distributed tracing. This fix ensures proper trace context
  propagation for outgoing HTTP requests.

- **Improved log ordering** - Fixed an issue where logs could appear out of
  order in certain scenarios. Logs now maintain their correct chronological
  sequence for better debugging and monitoring.
