## Summary by CodeRabbit

* **New Features**
* Enhanced observability: support for multiple trace exporters and
automatic sensitive-data redaction for improved monitoring and privacy.
* **Behavior Changes**
* Query serialization now encodes arrays and objects as JSON strings in
query parameters, changing how complex values are transmitted.
* **Documentation**
* Updated examples and guidance to reflect the new observability
configuration patterns.
