- Added TLS support and automatic certificate reloading for the gRPC Query server (currently disabled due to missing flag)
- Introduced multiple backend enhancements: configurable UDP socket buffer, Kafka producer batch flag, default batch/queued retry processors, trace anonymizer prototype, native OTEL Elasticsearch exporter, and switched hotrod to gRPC
- Fixed numerous bugs and minor issues including ES OTEL client URL validation, Elasticsearch version handling, collector shutdown order, Zipkin panic on shutdown, and pinned UI to version 1.10.0
