04.30.2025: Span Querying & Data Extraction for Phoenix Client 📊

Available in Phoenix 8.30+

The Phoenix client now includes the SpanQuery DSL, enabling more advanced and flexible span querying for distributed tracing and telemetry data. This allows users to perform complex queries on span data, improving trace analysis and debugging.

In addition, the get_spans_dataframe method has been migrated, offering an easy-to-use way to extract span-related information as a Pandas DataFrame. This simplifies data processing and visualization, making it easier to analyze trace data within Python-based environments.
